H06.25 Software Installation and Upgrade Guide

When migrating to AF_UNIX Release 2:
• If you start $ZPLS in a startup script using the SCF START SERVER command, and failure to
start $ZPLS causes the script to be aborted and steps following the failing one to be omitted,
modify the script to remove the command to start $ZPLS.
NOTE: In AF_UNIX Release 2, any changes to the #ZPLS attributes will have no effect.
• If you use the STARTOSS utility to start OSS processes, modify the
target-volume.ZOSSINS.OSSINFIL file by changing the line
SERVER #ZPLS
to
* SERVER #ZPLS
NOTE: target-volume is normally $SYSTEM.
NOTE: #ZPLS cannot be deleted from ZOSSSERV but can be deleted from OSSINFIL.
Commenting out the #ZPLS statement from the OSSINFIL prevents the STARTOSS utility from
issuing an error during execution.
The $ZLSnn processes are started automatically when the processors start; do not add them to any
startup or shutdown scripts.
Falling Back to An Earlier Version of AF_UNIX
If fallback is required:
• If you start $ZPLS in a startup script using the SCF START SERVER command, modify startup
scripts to start $ZPLS using the SCF START SERVER command.
• If you use the STARTOSS utility to start OSS processes, modify the
target-volume.ZOSSINS.OSSINFIL file by changing the line
* SERVER #ZPLS
to
SERVER #ZPLS
NOTE: target-volume is normally $SYSTEM.
This ensures that the OSS Socket Local Server is started correctly as system load.
The OSS Monitor included in AF_UNIX Release 2 software adds database records for the local
server 2 (LS2) processes. If fallback is required, HP recommends that, after the system is no longer
running an RVU containing AF_UNIX Release 2, you delete these records using the SCF DELETE
SERVER command:
ASSUME $ZPMON DELETE SERVER
#ZLS00 DELETE SERVER #ZLS01
...
DELETE SERVER #ZLS15
If you fail to delete the database records:
• The SCF INFO SERVER command will show $ZLS00 through $ZLS15 as UNKNOWN servers
with no parameters.
• Attempts to START, STOP, or ALTER $ZLS00 through $ZLS15 will fail with the diagnostic
"Configuration contains invalid data".

Guide.
