CURRENTS ENHANCE Your Expertise Small changes in recent z/OS releases can result in big improvements W hy do only some release enhancements get splashy attention when other, smaller items are just as fabulous? I've found many functions over the past several z/OS* releases that system programmers may not have realized were there. In fact, many of these items were the result of customer requirements, making their delivery even more important. Marna Walle is a senior technical staff member in the z/OS Build and Installation organization in the IBM Systems and Technology Group. Many of these enhancements are on releases your enterprise may already be running. They're easy to implement, meaning that you can take advantage of them right away. z/OS V2.1 Dynamic SYSDSN ENQ downgrade: This is the capability to allow a SYSDSN enqueue downgrade for batch jobs when 16 // JANUARY/FEBRUARY 2015 appropriate. When a step has completed in the batch job and all of the subsequent steps of the job only need an exclusively held data set as a shared enqueue, the enqueue can be downgraded. This allows other jobs that may need the data set with a shared enqueue the possibility to execute. Better batch parallelism could result. Parallel batch recall: Prior to z/OS V2.1, any migrated data sets were recalled serially at the job step level. As of this version, you have the option of indicating whether to recall all migrated data sets in the job step in parallel. Doing so reduces the delay for other jobs to use that initiator and may allow for better parallelism of batch execution. TCP/IP profile syntax check: Checking the syntax of profile configuration steps could be
