Problem:

Changed $OPTIONS $TPUNIT values and now receive the following error when starting IXR.

004_ ASMMN020 - IPC initalization error RC=20 RS=16 INF=36 _004 

Resolution:

$OPTIONS values are positional in design. There are a specific number of entries that can be used and it is not a variable list. YOu can use existing provided lines for your tape esoterics but you cannot add a new definition that does not already exist in the filed values that CA ASM2 provides. Remove any new lines you mave have added or replace any lines you may have removed.

Reassemble $OPTIONS using the SAMPJCL(L142IKE) job provided, refresh the LNKLST, and restart IXR.

Sample $TPUNIT values:
