Information in this document applies to any platform.

Symptoms

The "PRC: Update Project and Resource Base Summaries" program is taking more than 3 hours to complete after R12.2.5 upgrade.

We upgraded from R12.1.3 to R12.2.5
In R12.1.3, the program used to get completed in few minutes.

We reviewed the Doc ID 1635133.1 for the new Project Performance option 'Use Project Performance Reporting and Project Status Inquiry for Reporting' but this was not enough to improve performance.

The tkprof trace will show performance issue with similar sql calls:
  BEGIN PJI_FM_SUM_MAIN.SUMMARIZE(:errbuf,:rc,:A0,:A1,:A2,:A3,:A4,:A5,:A6,:A7);

  INSERT INTO PA_COMMITMENT_TXNS ( CMT_LINE_ID, PROJECT_ID, TASK_ID,
    TRANSACTION_SOURCE, LINE_TYPE, CMT_NUMBER, CMT_DISTRIBUTION_ID,
    CMT_HEADER_ID, DESCRIPTION, EXPENDITURE_ITEM_DATE, PA_PERIOD, GL_PERIOD,
  ...
    NULL AND PCTV.EXPENDITURE_TYPE IS NOT NULL AND PCTV.EXPENDITURE_CATEGORY IS
    NOT NULL AND PCTV.REVENUE_CATEGORY IS NOT NULL AND
    PCTV.SYSTEM_LINKAGE_FUNCTION IS NOT NULL
