    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

    IASP vary on vs. IPL

    1) Apply PTFs which deliver performance improvements:

    http://www-01.ibm.com/support/docview.wss?uid=nas8N1020998

    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

    Four ways to improve iASP Vary On performance

    http://www-01.ibm.com/support/docview.wss?uid=nas8N1020998

  • SAP on IBM POWER Summit DACH 2016 - IBM Corporation 2016

    Current PTFs for IPL / vary on IASP steps

  • SAP on IBM POWER Summit DACH 2016 - IBM Corporation 2016

    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

    Recent significant enhancements

  • SAP on IBM POWER Summit DACH 2016 - IBM Corporation 2016

    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)

    And more enhancements
