ECO NUMBER: VAXCMAR04_062 PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 UPDATE PRODUCT: OpenVMS VAX OPERATING SYSTEM 6.2 COVER LETTER 1 KIT NAME: VAXCMAR04_062 2 KITS SUPERSEDED BY THIS KIT: VAXCMAR03_062 3 KIT DESCRIPTION: 3.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS VAX V6.1, V6.2 3.2 In order to receive the full fixes listed in this kit the following remedial kits also need to be installed: None 3.3 Files patched or replaced for V6.2: o SYS$COMMON:[SYSLIB]CMA$OPEN_RTL.EXE image o SYS$COMMON:[SYSLIB]CMA$RTL.EXE image 3.4 Files patched or replaced for V6.1: o SYS$COMMON:[SYSLIB]CMA$OPEN_RTL.EXE image o SYS$COMMON:[SYSLIB]CMA$RTL.EXE image 4 PROBLEMS ADDRESSED IN VAXCMAR04_062 KIT o Paths to initiate time slicer for the pthread api and the exception returning api failed to enable the time slicer. -- COVER LETTER -- Page 2 15 January 1997 5 PROBLEMS ADDRESSED IN VAXCMAR03_062 KIT FOR OPENVMS V6.2 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. Hence products which only occasionally use threads do not have to pay the time-slice penalty when threads are never used. Note that once enabled, the time-slicer stays enabled for the process until the program which is using threads exits. 6 PROBLEMS ADDRESSED IN VAXCMAR02_062 KIT o When CMA$NOCACTUSSTACK is defined, cactus stack linking is disabled. This was done under a logical, as disabling cactus stack linking has the unpleasant side effect of disabling the ability to use DEBUG. There is a class of customers who require the cactus stack linking and can't be impacted by this change, but SWIFT customers require that we disable cactus stack linking. 7 PROBLEMS ADDRESSED IN VAXCMAR01_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. 8 PROBLEMS ADDRESSED IN VAXCMAR01_061 KIT o The customer visible symptom is that DECthreads hang in a call to cma_delay or any timed condition wait. 9 KIT INSTALLATION RATING: The following kit installation rating, based upon current CLD information, is provided to serve as a guide as to which customers should apply this remedial kit.
