ECO KIT SUMMARY:
An ECO kit exists for DEC SNA Application Services V1.2 on Digital UNIX
V3.2 or later. This kit addresses the following problems:
Problems Addressed in the R3270123 Kit:
o Session is in the unbinding state after received an unbind
o SNALOG file would type out as a single column file
o PRINT/FLAG would cause queue to stall with NOCALLTRANS error
o An Invalid Stimulus bugcheck would be signalled
o Exception Requests were not handled correctly
o MEP VT Would Occasionally Exit With an Internal Error
o MEP VT Would Occasionally ACCVIO
Problems Addressed in the R3270122 Kit:
o MEP VT would occasionally hang. This was caused by SNA 3270
Application Services passing an uninitialized data structure element
to MEP VT which caused the session id to become corrupted.
o DECforms: Error 12 displayed when running certain applications.
When running certain DECforms applications, the user would see the
following message:
Forms Error: -12
Device I/O error.
The error was caused by a change in a 3270 Services header file
(R3270DEF.H) which was not included in the V1.1 shipment of the
DECforms kits. This change has now been built into the DECforms
kits included with V1.2 of the 3270 Services software. If you are
using the DECforms software, install the latest kits (both 3270
Services and DECforms) contained in this ECO. If you have developed
an application on V1.0 or V1.1 of the 3270 Services software, you
may need to recompile your application after installing V1.1.
o Concurrent calls to r3270_connect() returned "invalid enable id"
error.
If a r3270_connect() call with a connect mode of RD_C_WAIT was made
while another r3270_connect() call was outstanding, the
r3270_connect() would fail with a sub-error of SNA_S_INVENAID.
o Reported routine name corrupted in R3270_S_PARERR error message.
The routine name in the "error in parameter, routine xxx" error
message would be corrupted and reported as random characters.
Problems Addressed in the R3270_E01012 Kit:
o Incorrect routine value returns.
The r3270_xxx() calls would incorrectly set the return value
to an error code of the form SNA_S_xxx, when called in BLOCKED
mode, instead of the correct R3270_S_xxx value.
INSTALLATION NOTES:
The ECO kit is distributed as a tar file containing the kit which can be
installed using the SETLD command. The tar file should be unpacked to a
suitable directory and then the setld command issued specifying that directory
as the source of the kit. Note that this is not an update kit, and the current
version of the R3270 must be deleted before installing this ECO.
For example, if the tar file containing the kit has been copied to
/usr/tmp/r3270.tar:
# setld -d R3270BASE120
# mkdir /usr/tmp/r3270
# cd /usr/tmp/r3270
# tar -xf /usr/tmp/r3270.tar
# setld -l ./ R3270BASE121
If the kit is delivered on tap11 then the commands would be:
# setld -d R3270BASE120
# mkdir /usr/tmp/r3270
# cd /usr/tmp/r3270
# tar x
# setld -l ./ R3270BASE121
Once the kit is installed, you should follow the instructions in the
installation guide for rebuilding the kernel then reboot the system and
configure the kit with the exception that it is not necessary to rerun the
initial configuration utility.
