OpenVMS ALPCMAR04_062 Alpha V6.2 CMA$RTL and CMA$OPEN_RTL 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. Copyright (c) Digital Equipment Corporation 1996, 1997. All rights reserved. PRODUCT: OpenVMS Alpha COMPONENT: DECthreads CMA$RTL.EXE CMA$OPEN_RTL.EXE CMA$ECO_DROP.COM (If desired, this command file may be used to remove the ECO and restore the original files and libraries if the previous versions were not purged during the installation.) SOURCE: Digital Equipment Corporation ECO INFORMATION: ECO Kit Name: ALPCMAR04_062 ECO Kits Superseded by This ECO Kit: ALPCMAR03_062 ALPCMAR02_062 ALPCMAR01_062 ECO Kit Approximate Size: 930 Blocks Kit Applies To: OpenVMS Alpha V6.2, V6.2-1H1, V6.2-1H2, V6.2-1H3 System/Cluster Reboot Necessary: No Installation Rating: 3 - To be installed on all systems running the listed versions of OpenVMS which are experiencing the problems described. ECO KIT SUMMARY: An ECO kit exists for CMA$OPEN_RTL and CMA$RTL on OpenVMS Alpha V6.2 through V6.2-1H3. This kit addresses the following problems: Problems Addressed in the ALPCMAR04_062 Kit: o Paths to initiate the time slicer for the pthread api and the exception returning api failed to enable the time slicer. Problems Addressed in the ALPCMAR03_062 Kit: o Prior to this change, the DECthreads time-slicer would be operational regardless of whether any threads had actually been created. This change delays enabling the time-slicer until the first thread create operation. Problems Addressed in the ALPCMAR02_062 Kit: o A non-Fatal exception that is raised is not caught in V6.2. This non-fatal exception was caught in V6.1. Problems Addressed in the ALPCMAR01_062 Kit: o When many threads are created and detached, it can be observed that calls to LIB$FREE_VM_PAGE are made during CMA$THREAD_CREATE that will sometimes mark pages as freed that were not owned/allocated by DECthreads. INSTALLATION NOTES: The system does not need to be rebooted after this kit is installed. However, if you have other nodes in your OpenVMS VMScluster, they should be rebooted or you should install this kit on each system in order to make use of the new image(s). REMOVAL INSTRUCTIONS: Remove this kit and restore the original files and libraries by logging into the SYSTEM account, and typing the following at the DCL prompt: @SYS$UPDATE:CMA$ECO_DROP
