OpenVMS VMS72_PTHREAD-V0200 Alpha V7.2 PTHREAD ECO Summary
TITLE: OpenVMS VMS72_PTHREAD-V0200 Alpha V7.2 PTHREAD ECO Summary
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for PTHREADS on OpenVMS Alpha V7.2. This kit addresses
the following problems:
Problems Addressed in VMS72_PTHREAD-V0200:
o A customer's application, when run with upcalls enabled, can die
with an ACCVIO. This is the result of a stack overflow while
running the application's exit handling routine.
o When a thread calls pthread_exit() the entire process is incorrectly
terminated by a %CMA-F-EXIT_THREAD error instead of simply
terminating the calling thread.
o Pagefault completions accumulate (as observed via the "pthread show
-u" command to SDA), with the corresponding waiting threads having
been, apparently, unblocked without consuming (i.e., freeing) the
completions. Also, sometimes threads are found waiting indefinitely
for completions (although this effect was never successfully
reproduced in-house), while other, mismatched completions remain
pending.
o Reduced performance and/or process threads hang.
Problems Addressed in VMS72_PTHREAD-V0100:
o ADA compiles were erroneously returning 'success' after
installation of the ALPPTHR02_071 remedial kit.
o ADA programs using certain TEXT_IO functions, when linked
without upcalls enabled, may hang with the manager thread
ready to run, but not running. Instead, the null thread is
running. The PTHREAD$RTL.EXE image may also produce an
UNALIGNRELO warning upon linking of the image.
INSTALLATION NOTES:
Install this kit with the POLYCENTER Software Installation utility by
logging into the SYSTEM account, and typing the following at the DCL
prompt:
PRODUCT INSTALL VMS72_PTHREAD /SOURCE=[location of Kit]
The kit location may be a tape drive, CD, or a disk directory that
contains the kit.
Additional help on installing PCSI kits can be found by typing HELP
PRODUCT INSTALL at the system prompt
No reboot is necessary after successful installation of this kit.
However, to make use of the new images on other nodes in the cluster you
must execute the following instructions after kit installation completes.
1. $ SET PROCESS/PRIV=OPER
2. $ MCR SYSMAN
3. SYSMAN> SET ENVIRONMENT/NODE=(NODE_1,NODE_2,NODE_N)***
4. SYSMAN> SET PROFILE/PRIV=(CMKRNL,SYSGBL)
5. SYSMAN> DO INSTALL REPLACE SYS$SHARE:PTHREAD$RTL
6. SYSMAN> EXIT
*** list any other nodes that boot from the system disk that the kit was
installed on. You do not need to include the node that was used to
install the kit.
