Are you recording SMF 19? IIRC this can greatly elongate the SMF dump process as the system goes to touch every online volume for each SMF dataset switch.
In your SMF dump job, add buffers, especially on the tape side. I am currently running with 50 and may increase it some more. The combination of the 2 techniques resulted in a cumulative 40% reduction in elapsed time. Other things to look at include the CISIZE of the MAN* datasets. <snip> We have noticed that our dumping for SMF MAN files are taking longer than usual. We see in the job log that when message IEC205I is issued, which shows the total blocks written, that sometimes it takes as long as 15 minutes for message IEF234E K to occur. Has anyone else encountered this or could explain to me why it takes 15 minutes for the IEF234E K message to occur? We realize that we need to get to logger but unfortunately it hasn't happened yet. </snip> This email including attachments may contain confidential information.
