3 IASP vary on vs. IPL IASP vary on is an IPL for a subset of storage Long IPL steps are likely to be long vary on steps IPL has console, IASP vary on has DSPASPSTS Most performance enhancements apply to both vary on and IPL Performance enhancements have been incrementally delivered

5 Four ways to improve iasp Vary On performance 1) Apply PTFs which deliver performance improvements: 2) Increase hardware resources Cores, Memory, I/O subsystem 3) Consider application/environment changes Eliminate inefficient practices to gain vary on/ipl efficiencies 4) Identify problem areas for IBM to investigate Many enhancements are direct result of customer investigations

6 Current PTFs for IPL / vary on IASP steps

7 Recent significant enhancements Database Initialization Reduced unnecessary deleted entry count recovery Customer had reduction from 90 to 20 mins, 120 to 22 mins Database Access Path Recovery Honor RECOVER attribute for Access Paths that are MAINT(*DLY) Customer had 5 hour reduction Spool Initialization Resolved problem and removed unnecessary processing

8 And more enhancements Database Recovery Pre-bring data more aggressively and remove unnecessary processing Reduced 14 mins to 7 mins New environment variable creates more QDBSRV jobs in IASP QIBM_IASP_QDBSRV_JOBS increases parallel Access Path recovery Journal Synchronization (and subsequent steps) Write Journal sync points to disk more aggressively to reduce recovery Vary off, Writing changes to disk Parallelized shutdown in 7.3 Removed 1 of 3 passes thru memory (also IPL enhancement)
