Usage notes for IEFOPZxx

After the optimization completes, change the parmlib members so that the state of these IEFOPZ-Old and IEFOPZ-New pairings is active, and issue SET IEFOPZ with the suffix list to process (and activate) these pairings (or re-IPL with a suitable IEFOPZ system parameter). The general rule is that a pairing applies only to allocations done after the pairing was activated.

• If a pairing relates to LNKLST libraries, you must use dynamic LNKLST operations to create and activate a new LNKLST that identifies the IEFOPZ-Old library (and the system automatically processes the IEFOPZ-New library as well). Only jobs that are started (or re-started) after this is done get the new data. If you want existing address spaces to get the new data, re-IPL or restart the job. As a last resort, you could try the LNKLST UPDATE operation with unpredictable results.
• If a pairing relates to non-LNKLST libraries that are managed by LLA, LLA adds to its management list the corresponding NEW library. (This will happen for a LNKLST library that is managed by LLA.) Any NEW library that was added to LLA previously remains within LLA management unless explicitly removed.
• For other cases, you might need to restart the relevant application/subsystem to get a new allocation that processes the updated data.
