Problem:

Hewlett-Packard has introduced some new twists on shared memory usage with the introduction of the HP-UX 11.11/i operating system.  Some of these HP enhancements required similar changes in Micro Focus Application Server runtime licensing, as well as the runtime licensing for Server Express Developer.  This article will cover these changes.

Resolution:

As more HP customers migrate their COBOL applications to HP-UX 11.11/i from older HP operating systems, which are no longer supported, Micro Focus SupportLine has recorded more cases of ASLMF memory failures.  Here are two that are particular to this environment and are easily resolved:

ASLM 1025 Due to misuse reboot is required

This error may not be solely caused by the change to HP-UX 11.11/i for shared memory windows but the problem persists in all Server Express 2.0.10, 2.0.11, 2.0.11 ServicePack1 and Server Express 2.2 and 2.2 ServicePack1 when running on this HP platform.

HP-UX 11.11/i customers need to apply the FixPack for Server Express 2.2 SP1 Fixpack 22.02_2 or later.  This FixPack contains the patch to ASLMF that recognizes the HP enhancement for shared memory and shared memory windows which requires that ASLMF check the setting for an HP internal parameter called IPC_GLOBAL.

Customers who require the previous Server Express versions for compatibility with third party vendor packages should request that their UNIX administrators ensure that the system configuration for shared memory windows not be applied.

At the time this article was created, Server Express 2.2 SP2, 4.0 and 4.0 SP1 have not experienced this particular error with the exception of those UNIX housekeeping utilities that clean up any and all shared memory usage.

ASLM: shm open fail

ASLM: Errno 2013

In 32-bit mode on HP-UX 11.11/i a new feature was introduced by HP to allow customers to increase memory utilization by about 1GB.  This option is set with the chatr command following the compile and link cob -x to a COBOL executable, for example, dummyread:

Set COBMODE=32

Export COBMODE

Cob -x dummyread.cbl

chatr s enable q3p enable dummyread

If the Server Express runtime (Application Server) version does not contain the ASLMF patch (as noted above for error ASLM 1025), then the execution of dummyread will fail with the ASLM 2013 error.  Or, if a prior version of Server Express had been installed on the HP-UX 11.11/I machine and then Server Express 2.2 SP2 (or later version) is installed, this error will persist until the ASLM shared memory contents have been totally reinitialized by a system reboot or by deleting and reinstalling the ASLMF software and Application Server license keys (or ./devas to restore Server Express Developer runtime licenses) .
