Tuning parameters

Use the TuningParameters stanza in the qm.ini file to specify options for tuning the queue manager.

ImplSyncOpenOutput=value

ImplSyncOpenOutput is the minimum number of applications that have the queue open for put, before an implicit syncpoint might be enabled for a persistent put, outside of syncpoint. The default value of ImplSyncOpenOutput is 2.

This has the effect that if there is only one application that has that queue open for a put operation, ImplSyncOpenOutput is switched off.

Specifying ImplSyncOpenOutput=1 means that an implicit syncpoint is always considered.

We can set any positive integer value. If you never want an implicit syncpoint to be added, set ImplSyncOpenOutput=OFF.
