You can define and init a SYSn.MANx dataset and it will be picked up after updating the parmlib SMFPRMxx member. If the dataset is not in use, you can delete, define, and init an existing SYSn.MANx dataset. However, you will need to have at least 2 available datasets to allow swapping, unloading, and init the inactive dataset.

Locates the new data set to open by starting at the top of the list of data sets specified on the DSNAME parameter of the SMFPRMxx member and looking for the first completely empty data set. Of course the trend is to switch to logstreams. https://www.ibm.com/docs/en/zos/2.3.0?topic=sums-switching-between-smf-logging-smf-data-set-recording On Wed, Mar 30, 2022 at 5:00 AM Jake Anderson <justmainfra...@gmail.com> wrote: > > Hello > > Is it possible to resize the SMF Man dataset on fly without an IPL ?
