DECnet/OSI DNVOSI_E15063 DECnet/OSI V6.3 For OpenVMS VAX ECO Summary
TITLE: DECnet/OSI DNVOSI_E15063 DECnet/OSI V6.3 For OpenVMS VAX ECO Summary

New Kit Date     :  14-SEP-2001
Modification Date:  Not Applicable
Modification Type:  Updated Kit  Supersedes DNVOSI_E14063

NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname.pcsi-dcx_axpexe, then it can
       be expanded by typing RUN kitname.pcsi-dcx_axpexe.  The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

Problems Addressed in DNVOSI_E15063:

A.  Corrections for Base Components
--------------------------------------------------------------------------------

Corrections made to SYS$LIBRARY:CDI$SHR.EXE:
       - Domain name search path processing does not require
         DOMAIN:.
       - Include support for Common Directory Service Dynamic Cache. 
       - Deassign BG device for TCP/IP restart.
       - Add support for sticky cache entry.
       - Set default cache expiration timer to 0 (i.e., infinite).
         (Previously the default was either 7 or 30 days)
       - Convert old V1.0 and V2.2 cache files to V2.3 cache files
         to preserve cache with upgrades.
       - Allow sticky cache entry even when sys$fullname is not defined.
       - ASTs needed to be disabled longer to protect the node information
         data structures from being corrupted.
       - Modify cache write logic around sticky bit changes.
       - Prevent access violations for some string manipulations in
         CDI search path.
       - Prevent system crash on return to session control with an
         invalid node parameter.
       - Allow DOMAIN to return a compressed name from the fully qualified
         domain full name.
       - Properly re-open the TCP/IP BG device channel for the TCP/IP
         DOMAIN lookups.
       - Prevent memory leak when looking up a null node name.
--------------------------------------------------------------------------------


Corrections made to SYS$SYSTEM:CTF$DCP.EXE:
       - Modify trace to collect remote records in the trace file,
         alpha only.
       - Modify collector to keep more trace records.
       - Add spinlocks so that two undeclare threads are forced to run
         serially in SMP environments.
       - Prevent possible system crash with invalid tracepoint address.
       - Change FAB and RAB parameters to increase disk I/O.
--------------------------------------------------------------------------------

Corrections made to SYS$UPDATE:DECNET_MIGRATE.EXE:
       - Include COLLECT and SHOW PATH correction for the error
         "Unsupported primary directory service."
       - Correct MOP Client NCL Script load file name.
--------------------------------------------------------------------------------

Corrections made to SYS$STARTUP:DNS$CLERK_STARTUP.COM:
       - Allow the user to specify the location of the NCL script
         via logical name definitions.
       - Add DNS$ADVER_AST_LIMIT logical and increase clerk quotas.
         Translate each of the logicals from the system table if it exists,
         otherwise use the defaults. Increase default quota for direct I/O,
         file_limit, enqueue limit, queue limit, adver_buffer_limit, and
         adver_max_working_set.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:DECNET_REGISTER.EXE:
        - Use DECdns high confidence to register nodes correctly.
          This prevents the error:
          %DNS-E-UNKNOWNENTRY, Requested name does not exist.
          After the initial error, the node object was deleted, but
          the .DNA_BackTranslation was left so that subsequent attempts
          to register the node failed with "name already in use".
--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:DTSS$SERVICE.EXE
      - Correct PGFIPLHI crash on startup. Insure that any linkages which
        may be touched at an elevated IPL are in a page which is locked.

--------------------------------------------------------------------------------

Corrections made to SYS$LIBRARY:DTSS$SHR.EXE
      - Modify user callable DTSS routine "mulftime" as this returned
        a value that is inaccurate starting with the lsb of the high
        order longword, with all lower order longwords being similarly
        inaccurate.
--------------------------------------------------------------------------------

Corrections made to SYS$STARTUP:DTSS$STARTUP.COM:
       - Allow the user to specify the location of the NCL script

         daylight savings time from the last Sunday in September
         to the last Sunday in October.
       - Change DTSS Brazilian time zone rule.
       - Change DTSS British time zone rule from 4th Sunday in
         October to 5th Sunday in October.
         NET$CONFIGURE.COM must be run to update these rules.
--------------------------------------------------------------------------------
Corrections made to SYS$LOADABLE_IMAGES:LES$LES_V30.EXE
       - Item list definitions had to be harmonized between VAX and Alpha
         to prevent system crashes on Alpha.
       - Prevent crash in LES$LPD_DONE when running SNA TE session over
         a QLLC link.
--------------------------------------------------------------------------------
Corrections made to SYS$LOADABLE_IMAGES:LES$NETMAN.EXE:
       - Include for compatibility with LES$NETMANLDR.
--------------------------------------------------------------------------------
Corrections made to SYS$LOADABLE_IMAGES:LES$NETMANLDR.EXE:
       - Correct NET$SHUTDOWN hang on FDDI circuits when executing the 
         "delete routing circ *" command.
       - All NCL SHOWS require NET$EXAMINE or NET$MANAGE or BYPASS,
         and NCL Actions require NET$MANAGE or BYPASS.
       - Corrections for routing and VAX P.S.I. event logging.
       - Allow duplicate attributes for LES-managed entities, i.e.
         routing and X.25.
       - Prevent crash on sanity check in Les_sync_suspend.
       - Correct the timestamp on a routing event.
--------------------------------------------------------------------------------
Corrections made to SYS$LIBRARY:LES$NETMANSHR.EXE:
       - Include support for compatibility with LES$NETMANLDR.
--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:NCL.EXE:

       - Modifed SetDefaultEntity, SetDefaultAccess and SetDefault routines
         to correct memory allocation and new defaults.
       - Correct default entity and global parsing vector when the initial
         connect attempt failed.
       - "With" cause corrected to allow parsing end user specification
         attributes using the UIC format.
       - Correct default entity and global parsing vector when the initial
         connect attempt failed.
--------------------------------------------------------------------------------
Corrections made to SYS$LIBRARY:NCLSHR:
       - Prevent NCL commands with embedded slashes, such as OSAK 
         commands, from returning an NCL success status even 
         if they fail.
       - Modify UIC format of an end user specification filter to
         return the %NCL-E-BADVALUE error when necessary.
       - Suppress "getlist" error on NCL SHOW displays
--------------------------------------------------------------------------------
Corrections made to SYS$SYSTEM:NCP.EXE:
       - Prevent possible access violation with proxies.
       - Correction for Show Known Nodes Characteristics.
--------------------------------------------------------------------------------
Corrections made to SYS$UPDATE:NET_ISHFILTER.EXE:
       - Include support for NET$ROUTING_ES.
--------------------------------------------------------------------------------
Corrections made to SYS$SYSTEM:NET$ACP.EXE:
        - Include support for CDI$SHR.EXE
--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$ALIAS.EXE:
       - Alias member with selection weight set to 0 should
         not receive any incoming alias connection.
       - Correct single member cluster alias selection weight.
       - Correction for incoming alias objects over 128.
       - Prevent alias hang on startup. If NET$ACP was very busy,
         the alias task could sometimes get suspended while
         holding the object lock in exclusive mode. The solution
         is to increase the priority of the alias task.
       - Correct alias selection weight of one.
       - Correct the format of the Phase V node address in Alias 
         forwarding packets to prevent logical links from being
         unexpectedly aborted.
       - Prevent possible system crash if the alias round robin
         queue was corrupted by disabling the AST delivery when
         the alias port was toggled.
       - Allow only the use of ALIAS DISABLE instead of ALIAS DELETE
         because the port should not be deleted once it has been
         allocated and accessed.
       - Correction for incoming selection weight on objects.
       - Prevent startup hang during the enable while waiting
         for the Object lock that was held in exclusive mode
         by another alias member.
       - Prevent Round Robin queue corruption.
--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:NET$CCR.EXE:
       - Modify "%CCR-F-UNRCMIPRSP, unrecognized CMIP error status" to
         "%CCR-F-ACCESSDENIED, NET$MANAGE, NET$DIAGNOSE or BYPASS required".
--------------------------------------------------------------------------------

Corrections made to SYS$MANAGER:NET$CONFIGURE.COM: 
       - Correct defaults for the routing "end system hello time" 
         and the session "update interval" when NET$CONFIGURE is
         run twice without exiting.
       - Correct node rename.
       - Find PSI$050.PSI in SYS$COMMON, which is needed for VAX P.S.I.
         to configure.
       - Correct attributes for FDDI devices and the associated 
         routing circuits.
       - Session control "application add" will default to "false"
         for outgoing alias.
       - Correct search for Phase IV node name database in SYS$COMMON.
       - Correct the use of SYS$COMMON for DECnet Migration
         temporary files.
       - Require LOCAL in the Session Control Search Path
         on DECdns servers.
       - Correct the use of logical name definitions for script
         files.
       - NET$STARTUP_RENAME.COM could be created with an invalid
         node name.
       - Add a Flow Control Policy Option for NSP Transport.
       - Correct DCL command syntax error on NSP configuration
         section within option 4.
       - Correct circuits to be configured as FDDI.
       - Add spaces in fddi_yes = 1.
       - Modify text for the EWdevice to indicate that it can be a DExxx
         device. Also add EB device.
       - Modify error handling on temporary files.
       - Prevent  %RMS-W-RTB,  byte record too large for user's buffer.
       - Correct password generation.
       - Change NET$CONFIGURE option 1.
       - Remove obsolete decnet_loc_register calls.
       - Display a warning that the sysem must be rebooted if the
         DECnet address has been changed.
       - Make sure that all temporary files from an aborted session
         will be deleted.
--------------------------------------------------------------------------------
Corrections made to SYS$UPDATE:NET$CONVERT_DATABASE.EXE:
       - Remove erroneous log file message "found 0 nodes".
       - Prevent database conversion to an invalid command:
         "SET NODE 0 CSMA-CD STATION MNA-0 STATION BUFFERS 15"
         in NET$CSMACD_STARTUP.NCL.
       - Add support for the DEFPA device.
       - Convert the Phase IV routing maximum visit count of 255 to
         the Phase V limit of 63.
       - Properly convert FDDI device, DEFPA, from Phase IV. The
         communications port should have been FWA not FPA.
--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$DRIVER.EXE:
       - For DNA, map NET$_CONTIMEOUT to the SS$_LINKEXIT system service
         status/MSG$_EXIT mailbox message type instead of to the
         incorrect SS$_UNREACHABLE/MSG$_PATHLOST.
       - Prevent access violation on zero length probe.
       - Prevent crash in sys$network_services by reordering IRP
         completion.
       - Prevent remote shutdown from stopping local servers by mapping
         remoteshut to msg$_abort and the ss$status to LINKABORT.
       - Allow the channel to be re-used after the reception of
         a msg$_netshut or msg$_thirdparty mailbox message.
       - Modify mapping table for Phase IV compatibility:
           A) When session is disabled an attempt to connect:
                1) Mailbox Message MSG$_Reject    
                2) %System-F-Shut, remote node no longer
                   accepting connects
           B) When session is disabled with existing connections:
                1) Mailbox Message, Msg$_Thirdparty
                2) SS$_Thirdparty abort status
       - Correct incoming disconnect with DNA where a
         a UCB was not deallocated.
       - Correct disconnect path that could lead to hanging
         transport ports if the outgoing connect initiate was
         not getting properly disconnected.
       - Correct mailbox disconnect message by removing
         an invalid check for a corrupt QLB queue in IO$_ACCESS.
       - Include spinlocks to synchronize all I/O completion.
       - Always delete the session association when an incoming
         connection times out.  If many incoming connections failed,
         this could eventually lead to a resource exhaustion and
         a system crash.
       - SMP synchronization was added to the executeDeAccess
         to prevent a network device hang on a very heavily loaded
         system.
       - Prevent possible system crash on an incoming connect timeout
         where close association could have been called twice.
       - Correct PFGIPLHI crash in execute deaccess.
       - Prevent possible application RWAST or network device hangs with
         QIOUCB$V_closeassocdone.  Double close associations precipitated
         this modification.  Both QIO_EXECUTE and QIO_COMPLETION were
         modified to add a new bit to check if the association has already
         been closed and if the channel can be deallocated.
       - Modify disconnect data counted string to emulate Phase IV behavior
         of stepping on the first byte of user data to make it a counted
         string IF the user application did not supply this necessary count.
       - Correct ExecuteDeaccess code latency when the connection was not
         yet in the run state and it was aborted.  This will now allow the
         abort to happen if 1) the channel type indicates that there is some
         semblance of a connection and b) in all states except for those that
         indicate that the connection is already in the process of being torn d
         i.e., ACinProg, CAinProg or DCinProg.
       - Prevent NET device $ASSIGN before the driver has been initialized.
       - Prevent possible page fault at elevated IPL bugcheck in deaccess.
       - Acquire and release IOLOCK8 in a macro for the DAB queue.
--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:NET$EVENT_DISPATCHER.EXE:
   Image Identification:   "V6.3-ECO11"    22-JUN-1999 14:30:28.19
       - Prevent INVEXCEPTN crash in SYS$NETWORK_SERVICES.
       - Create new filters to block the following CSMA and FDDI events
         to correct the command RESET EVENT DISPATCHER OUTBOUND STREAM.
         The global filter will block the following events by default:
            ((node,csma,station), unrecognized multicast destination pdu)
            ((node,csma,station), unavailable station buffer)
            ((node,fddi,station,link), unrecognized multicast pdu destination)
         If you do not want these events blocked by default at creation
         time, create a new SYS$MANAGER:NET$EVENT_LOCAL.NCL by copying
         the NET$EVENT_LOCAL.TEMPLATE and include appropriate commands to
         pass one or more of these events.
--------------------------------------------------------------------------------

Corrections made to SYS$MANAGER:NET$EVENT_LOCAL.TEMPLATE:
       - If a NET$EVENT_LOCAL.NCL was previously created from the old
         NET$EVENT_LOCAL.TEMPLATE, then your site-specific
         NET$EVENT_LOCAL.NCL should be edited to remove the following
         duplicate block command:
         BLOCK EVENT DISPATCHER OUTBOUND STREAM local_stream
         GLOBAL FILTER ((NODE,MOP,CIRCUIT), Unrecognized Dump Client).
       - Since new filters now block the CSMA and FDDI events by default,
         the following pass commands have been added:
         !PASS EVENT DISPATCHER OUTBOUND STREAM * GLOBAL FILTER -
         !   ((NODE,CSMA-CD,STATION), Unrecognized Multicast Destination PDU)
         !PASS EVENT DISPATCHER OUTBOUND STREAM * GLOBAL FILTER -
         !   ((NODE,CSMA-CD,STATION), Unavailable Station Buffer)
         !PASS EVENT DISPATCHER OUTBOUND STREAM * GLOBAL FILTER -
         !   ((NODE,FDDI,STATION,LINK), Unrecognized Multicast PDU Destination)

         If you have previously created a NET$EVENT_LOCAL.NCL script by
         copying the old .TEMPLATE, regardless of whether you choose to use
         these commands or not, please update that site-specific
         NET$EVENT_LOCAL.NCL script.
--------------------------------------------------------------------------------
Corrections made to SYS$LOADABLE_IMAGES:NET$LOOP_APPLICATION.EXE:
   Image Identification:   "V6.3-ECO08"    28-JUL-1997 17:49:53.13
       - Prevent NET$MIRROR_SERVER from consuming CPU time.
       - Correct application loopback error "Agent is invalid"
         when connecting by destination tower.
--------------------------------------------------------------------------------

Corrections made to SYS$SYSTEM:NET$MOP.EXE:
       - Save unnecessary disk access on dump requests.
       - Add a new diagnostic error for Console Carrier Request
         "CCR$_DuplicateAddr, duplicate address error" to help
         resolve a configuration error.
       - Prevent SSRVEXCEPTN crashes in NET$MOP. One of these 
         crashes (Alpha only) occurred in response to NCL BOOT MOP 
         CLIENT and TSM TRIGGER SERVER.  Also fixed various other 
         SSRVEXCEPTN crashes (on both VAX and Alpha) that were caused 
         by MOP's use of $CMA thread routines in kernel mode.  Those 
         crashes were recognizable by kernel stack corruption, and they 
         could occur while TSM, MOP, or the NCP Emulator were in use.
       - Modify the CCR timer to allow SET HOST/MOP and TSM
         commands to complete more quickly when one or more of the
         remote consoles is unavailable.
--------------------------------------------------------------------------------
Corrections made to SYS$LOADABLE_IMAGES:NET$MOPS0.EXE:
       - VAX only correction for a kernel dispatch table
         to a nonpaged psect.
       - Included for compatibility with NET$MOP.
--------------------------------------------------------------------------------

Corrections made to SYS$LIBRARY:NET$NISCS_LAA.EXE:
       - Alpha only - Permit loads from devices using SCSI PACs
         (Port Allocation Classes).
       - Prevent KRNLSKNV crash during load with host based shadowed disk.
--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$OSDRIVER.EXE:
       - Correct incoming disconnect with VOTS when a
         a UCB could fail to be deallocated.
       - Prevent system crash when running a VOTS trace with a
         bad NCB descriptor.
--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$OSVCM.EXE:
       - Corrections for Passive TSEL (defined by NCL) that is deleted
         when the program subsequently declares TSEL and exits.
       - Correct lost "fillm" when a connection was not processed
         by the application before the timeout.
--------------------------------------------------------------------------------

Corrections made to SYS$LIBRARY:NET$PROCESS_EMAA.EXE:

       - Check the packet size against datalink buffer size for
         all packets.  Do not send probe packets if the datalink
         size is too small.  When flooding the circuits, segment 
         packets if necessary.
       - In the HDLC VCI interface, if the datalink reported an 
         unusable port with an unexpected reason code, report a physical

--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$SESSION_CONTROL.EXE:
       - Correct DNA CONTROLCOMPLETE while processing connect accept

       - Correct outgoing connect timer synchronization caused by threads
         starting and stopping this timer.
       - Reduce the amount of time required to report that an application
         does not exist.  This time was not being reported until after the
         incoming timer expired.  The connection will now be rejected as
         soon as Session determines that the application does not exist.
       - Correct the disconnect reason code used when an incoming connection
         request times out.  Use SCL$K_RC_TimedOut as the disconnect reason
         code when an incoming connection request times out without
         being either explicitly accepted or rejected by the user
         application.
       - Modify $IPC user data to be compatible with $QIO by adding
         receive disconnect user data to the RECEIVE_EVENT function.

         SCL_BASE_ACP incorrect status check on backtranslaction.
       - Change the disconnect status sent to the remote node when
         session control is disabled on an existing connection from
         "%SYSTEM-F-SHUT, remote node no longer accepting connects" to
         "%SYSTEM-F-THIRDPARTY, network logical link disconnected by a

       - Conditionalize out SCL spinlock checking because this check is
         now obsolete.

         A stale pointer in DNSResult[DNSREQ$A_Pointer] with
         ACP$CheckBackTransTask could cause a double deallocation.
       - Resolve SMP PGFIPLHI trying to access an EIB port that no
         longer existed.
       - Include proxy information for use by LOGINOUT with SYSGEN
         parameter, NET_CALLOUTS 255.

       - Correct "Incoming Connect Orphan Queue" VCRP disconnect
         deallocation.
       - Modify EXE$IPC to always return the caller to IPL 0 so that
         callers will never unknowingly inherit the ASTDEL IPL.
--------------------------------------------------------------------------------
Corrections made to SYS$MANAGER:NET$SHUTDOWN.COM:
       - Allow DECdns Clerk shutdown to be last.
       - Check for the existance of a NET$APPLICATION_SHUTDOWN logical which,
         if used, should point to a site-specific application shutdown
         procedure. If the logical is defined and the procedure exists,
         NET$SHUTDOWN will execute that procedure.  The NET$AUX_CONTROL
         logical will continue to use the previously defined indexed file.
       - Prevent NET$SHUTDOWN from aborting when a NET process logical
         was defined.
--------------------------------------------------------------------------------

Corrections made to SYS$LOADABLE_IMAGES:NET$TPCONS.EXE:
       - Change handling of Report Event VCRPs, for Alpha only.
       - Prevent hanging tcp links by rejecting the connection on the 
         listen port (tpcb) when this initiation fails.

         connect error conditions eventually cause the available
         sockets to become exhausted.
       - Prevent possible system crash on a disconnect indication.
       - Remove statetable bugchecks.
       - Include VCIB sanity checks in all locations which fork to a 
         completion routine since it is theoretically possible for an 
         I/O completion after port deletion in any of these routines.
       - Correct a  design problem  to allow for very long latency in
         TCP/IP Services  between the transmit request and the actual
         completion,  if  there are any problems in TCP/IP delivering
         the data message.
--------------------------------------------------------------------------------

         greater than 20.
       - Disconnect data from Phase IV nodes was incorrectly reported
         as a protocol error.   When io$m_synch was used, the mailbox
         read hung waiting to receive a disconnect with optional data.
       - The default retransmits was lowered from 12 to 8 for faster
         error detection and recovery.
       - NSP connect initiate will be resent every 5 seconds instead
         of 10 seconds.  This allows NSP to timeout before session by
         default even when the remote node is not reachable.
       - NSP was corrected to prevent logical links from hanging on
         a retransmission of an interrupt message.
       - Insure that I/O will complete even if the IO$_Multiple bit is set
         in the QIO function.
       - Allow NSP flow control to be more efficient and deliver the
         XON as soon as possible after a new receive request is received.
       - Prevent a remote TCID from attempting to be reused for a
         connection if the previous connection failed to be deaccessed.
       - Corrected the possible delivery of protocol errors with disconnect
         data.  If the user string (P2) is not a counted string this will
         now be included on behalf of the user.  Phase IV compatibility also
         writes over the first byte of the user data while making it counted.
       - Allow a connection to be disconnected immediately for a dysfunctional
         link rather then waiting for the timeouts to complete.

         leak (CONSTmpList memory leak) and, in one instance, to 
         a pool corruption.
       - Add "try hard" for "keep alive" acknowledgements to allow idle 
         link failover.

       - Prevent possible crash with deactivate port.
       - Prevent crash with maximum connections. 
       - Prevent possible crash when expedited data had just been
         transmitted and the message sequence number to be
         retransmitted did not match the expected message.
       - Correct Alias Transport Connection Table for connections
         using cluster alias because the TC ID range was not
         properly allocated.
       - Prevent a crash on connect initiate where the port had not
         yet been activated and the solicit VCRP was zero.
       - Prevent a crash when a port block was inserted into a queue
         in the RSP (Remote Service Provider) and an element in the
         queue found an invalid pointer.
       - Correct the checksum calculation for messages larger than
         4,399 bytes.
       - Prevent crash in OSITP disable port if this same port had
         already been disabled.
       - Remove forced bugcheck from BUILD_DATA routines.
       - Insure that I/O will complete even if the IO$_Multiple bit is set
         in the QIO function.
       - Prevent transport bugcheck when an X.25 connection was abnormally
         terminated and a protocol error was in the process of being logged.
       - Correct timing window to prevent a VCRP leak if user data could
         not be delivered to the application because it was disconnected.
       - Correct possible crash when the port is found and the associated
         remote TCID was not valid.
       - Modify state tables such that if the port is in a WFNC state and
         receives a DR or DC, just ignore the message rather then bugcheck.
       - Correct restraint mode window.
       - Correct default packet size when remote fails to set the size.
       - Prevent OSITP retransmission timeouts with zero credit.
       - Prevent OSITP premature port deallocation.
       - Change  the  action routine  on a TPDU error in a WFNC (wait for
         network  confirm) state  to ACT$P_TPDUERR rather then bugcheck.

                         DNS$ADVER_AST_LIMIT
                         DNS$ADVER_BUFFER_LIMIT
                         DNS$ADVER_EXTENT
                         DNS$ADVER_MAX_WORKING_SET
                         DNS$ADVER_PAGE_FILE
         These  logical  names  correspond  to  qualifiers  on  the  RUN
         statement which are described in the OpenVMS documentation.  If
         any of  these  logical  names  are  defined  at  the  time  the
         DNS$ADVER  process starts up, then the values defined for these
         logical names are used instead of the default quotas.

         Typically, these logical names are defined in the file:
                     SYS$MANAGER:SYLOGICALS.COM

         This is necessary because the logical names need to be  defined
         before the DNS$ADVER process starts up.

         One reason for using these logical  names  is  if  you  have  a
         system  is  configured with more than two ethernet controllers.
         Another reason is to define increased quota for  the  DNS$ADVER
         process  when  you  receive  a  message  on  the console during
         startup   that   the   DNS    cache    is    not    initialized
         (DNS$_NOCACHE,"Clerk cache not initialized").

         Selected default quotas for the  DNS$ADVER  process  have  also
         been  increased  for the ECO 72.  The selected quotas that have
         been increased include direct I/0, enqueue limit, queue  limit,
         buffer limit and maximum_working_set.

      o  Corrected the clerk treewalk algorithm to prevent the algorithm
         from  failing  to find the desired clearinghouse to satisfy the
         name lookup request.  Typically, the symptom  of  this  problem
         was  the  return  status  of  DNS$_NOCOMMUNICATIONS  on a "SHOW
         CLEARINGHOUSE ..." command when the clerk should have been able
         to connect the proper clearinghouse.

INSTALLATION NOTES:
          
Install this kit with the POLYCENTER Software Installation 
utility (PCSI) by logging into the SYSTEM account, and 
entering the following command at the DCL prompt:

$ PRODUCT INSTALL DNVOSIECO12/SOURCE=[location of the .PCSI file]

Note that you can use the DECwindows Motif interface to PCSI 
if you wish.

For the corrections to take effect, you must reboot the system.
If you are a member of a VMScluster, you must reboot the entire
cluster.  You can postpone rebooting if it is not convenient 
for you to do so now; however, the new driver(s) will not take 
effect until after a reboot. 

Installation Caution
 
After you install this ECO kit, an error in the POLYCENTER
Software Installation (PCSI) prevents installation of the
OSAK SPI Interface V3.0.

The OSAK PCSI installation requires DECnet/OSI V6.3,
which causes the installation process to remove 
DNVOSIECO15.  This situation leaves the system without a
SYS$NETWORK_SERVICES.EXE file. Therefore, the system
cannot be rebooted.
 
You must preserve the original installation order,
indicated below. This will be corrected in a future release.
 
Installation Order
 
Place each PCSI kit in a unique source directory
 
   1) DECNET_OSI V6.3 /Source=[KITS.DECNET] 
   2) OSAK V3.0-L /Source=[KITS.OSAK]
   3) FTAM V3.2-F /Source=[KITS.FTAM]
   4) DNVOSIECO15 V6.3 /Source=[KITS.ECO]
