or pointers within that data (MTTR/ MQTR), etc. Jobs and applications still reference SPOOL2 data, and JES2 automatically remaps their old SPOOL2 MTTR/MQTR pointers to the new location in the SPOOL5 data set using the SPOOL2 DAS mapping information. So when does JES2 no longer require the MAPPED SPOOL2 DAS? When the last job that thinks it has space allocations on SPOOL2 goes away, the logical representation of SPOOL2 will also go away. The $DJQ,SPOOL=VOL=SPOOL2 command shows jobs that think they have space allocations on SPOOL2. Keep in mind the target volume SPOOL5 cannot itself be migrated until all volumes mapped to it are gone.

Tom Wasik is the team leader in JES2 design and development at IBM Rochester. He’s spent 28 years working on JES2 at IBM.

Alexei Pytel is an advisory software engineer working in z/OS* JES2 development since 2007. He’s been with IBM for 19 years.

Kevin Kathmann is an advisory software engineer working in JES2 development since 2008. He’s worked with IBM for more than 20 years.

We will also DISCUSS HOW TO JOIN THE #)#3 4RANSACTION Server V5.1 Open Beta program. FEATURING:

Digging Deeper We’ve only touched on the basics of spool migration. More information can be found online (www.ibm.com/systems/z/os/zos/ jes2_spoolmigration.html). Be sure to check out the FAQ link, which covers many basic questions. A link to the migrating spool volumes overview in the JES2 commands section is also a must-read. The second installment of this series at ibmsytemsmag.com/ mainframe/adminstrator/migration/ spool_part2, explores how the migration is coordinated among all MAS members, in particular, the COPY and CATCHUP phases.
