According to this from z/os, it looks like the log streams would have to be disconnected in order to update LOGSNUM. But CICS TS 5.1 will not let you disconnect the main journal DFHLOG. And I do not even see any option in IXGINVNT (Z/OS 1.13) to update LOGSNUM. REQUEST=UPDATE option of IXGINVNT z/OS MVS Programming: Assembler Services Reference IAR-XCT SA22-7607-17 The IXGINVNT macro with the UPDATE parameter allows a program to update a log stream entry in the LOGR policy for a coupling facility or DASD-only log stream. Except for the RETPD and AUTODELETE parameters, note that you cannot update a log stream while there are active connections to it. And this from CICS DOC: 2.You cannot update AVGBUFSIZE, like other structure definition attributes such as MAXBUFSIZE and LOGSNUM, unless you first delete the log streams in the structure definition. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Richards, Robert B. Sent: Monday, March 30, 2015 12:27 PM To: [email protected] Subject: Structure resizing for CICS LOG lostreams I have a coworker that wants to increase the LOGSNUM value of the structure defined for numerous CICS DFHLOG logstreams. Can this be done dynamically and will we have to make sure that all regions are down and delete/define with the larger value. I have tried RTFM but it was not intuitively obvious.
