I would look in the SMF manual. The current version for z/OS 2.1 is SA38-0667-02
Without looking it up: The system will attempt to write to SYS1.MAN1 (as specified in SMFPRM00). If SYS1.MAN1 is not available (full or otherwise), SYS1.MAN2-n are used in sequence, If SYS1.MAN1 is made available while SYS1.MAN2-n are in use, the system will return to SYS1.MAN1 at the next SMF switch. ZEOD writes the current set of SMF buffers and closes the current MANx. If ZEOD is not issued, SMF will resume writing to the "current" MANx dataset (be it 2 , 3, 9, 10 or whatever) until full and then will behave as described above. HTH, <snip> We have six MAN datasets spread across three volumes; I notice that the ‘I SMF’ command switches between only the first and second MAN datasets. Is there any doc, explaining how SMF processes the MAN datasets? On our two production systems a ‘Z EOD’ command is issued when the system comes down for an IPL, when will SMF write to MAN3, 4, etc.? On our systems programming LPAR, where no ‘Z EOD’ is issued, I do see SMF writing to MAN datasets beyond MAN2, when the system is IPL’d. </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
