If you need to change the staging data set size for a DASD-only log stream because of a change in conditions or in response to monitoring SMF record 88, note that the staging data set must actually be deleted and then reallocated in order to change. This is because the staging data set size and other log stream attributes are defined at allocation and remain in effect until all the connections to the DASD-only log stream have disconnected.

To change staging data set size, do the following:

1. Have all connections to the DASD-only log stream disconnect.
2. Change the STG_SIZE parameter in the LOGR policy to a new value.
3. Have all connections from the system reconnect to the log stream.

If the update of the staging data set size does not work, it might be because the system is still connected to the log stream. Use the LIST request on the IXCMIAPU utility to see if the system is still connected. Make sure that the system is disconnected, by canceling the job if necessary, before changing the staging data set size in the LOGR policy.
