Learn how to identify threadsafe candidates and capture baselines using standard SMF data and reports from CICS Performance Analyzer (PA). Understand which CICS SMF record fields are used for analysis. Learn how to determine which applications and transactions are good candidates for threadsafe and which ones will bring the largest benefit with the smallest amount of work. Learn how to identify transactions currently using large amounts of CPU because of TCB switching, how many switches (change modes) occurred and CPU costs. Having analyzed the SMF data to determine candidate applications based on transaction performance characteristics, learn how to determine good candidate programs for threadsafe based on program behavior. Identify threadsafe ready programs for immediate benefit, commands causing potential data integrity issues, view TCB switching in a graphical chronological view of a transaction and see the affect of a threadsafe change. Learn how to quickly change resource definitions to enable threadsafe and perform testing. The last step of the process takes you through the CICS PA benchmarking process using transaction profiling to quantify the results of your efforts. This methodology is based on the 4 step process to threadsafe applications in the Redbook, "Threadsafe Considerations for CICS".
