Hello Community, this entry describes a performance enhancement involving the current plan VSAM dataset LSR buffering to be used in case of big workloads. Apar PM12394 that implements the enhancement, is available all TWS for z/OS releases (8.3.0 and later). The use of parameters CPBPLIM and CPDTLIM in controller OPCOPTS can cause performance issues when storage fragmentation occurs due to big plans execution. CPBPLIM allows to choose which percentage of the available storage can be used to allocate the buffers, CPDTLIM allows to choose... [More]
Hi All, The solution reported at the following link (it's from the "integration scenarios" wiki) can be useful for all TWS for z/OS admins using the TEP integration: http://www.ibm.com/developerworks/wikis/x/dQX8Cw That link has an attached document describing how to implement a solution entirely based on a TEP feature (the link to ) allowing to create a "launch in contest" link between different table spaces.
