Re: Resize SMF MAN without IPL
You must make sure the new data sets have the same CI size. If you change the CI size, you must IPL. https://www.ibm.com/docs/en/zos/2.3.0?topic=sets-selecting-smf-data-set-control-interval -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: Resize SMF MAN without IPL
IIRC you need to remove the dataset you intend to delete from the SMFPRMxx member, set that member as active T SMF=xx then you can delete and redefine, I've done this a couple of time, works well that way, I have 3 SMFPRMxx members still setup to do this. We're using log streams now but the SMF MAN datasets are still defined in the member for backup Carmen Carmen Vitullo -Original Message- From: Jake To: IBM-MAIN Date: Wednesday, 30 March 2022 12:58 AM CDT Subject: Re: Resize SMF MAN without IPL The only challenge I can see is that I can't resize an existing one as it gives me message as 'In use'.

Re: Resize SMF MAN without IPL
Try changing parmlib to remove it then swap to a new data set. It might deallocate the dataset. Or just create a new one of the desired size and update parmlib then delete the old one after a swap or IPL.

Re: Resize SMF MAN without IPL
Thanks Mike So just pick the non-active one.(with zero %),. Delete them. Then Define a new SMF MAN and preformat and do /T SMF=00. Is it correct?

Re: Resize SMF MAN without IPL
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. https://www.ibm.com/docs/en/zos/2.3.0?topic=sets-using-define-create-smf-data https://www.ibm.com/docs/en/zos/2.3.0?topic=sets-switching-smf-data When the SMF data set that is currently being recording on becomes full, SMF does the following: Automatically closes the full data set, making it available for dumping. 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 wrote: > > Hello > > Is it possible to resize the SMF Man dataset on fly without an IPL ?
