2.3.3.1.1 Configure Oracle TimesTen Checkpoint Frequency

To ensure Oracle Business Intelligence Enterprise Edition sets the Oracle TimesTen checkpoint frequency, perform the following configuration steps after upgrading Oracle TimesTen In-Memory Database. Failure to perform this configuration may adversely affect Oracle TimesTen performance.

To configure Oracle TimesTen checkpoint frequency:

  1. Open the timesten-install-dir/info/sys.odbc.ini file.
  2. Find the DSN entry for the schema used for Aggregate Persistence.
  3. Do one of the following:
    • If you are loading data in Oracle TimesTen database using aggregate persistence, edit the three parameters as follows:

      • CkptFrequency=-1

      • CkptLogVolume=0

      • CkptRate=0

    • If you are loading data in Oracle TimesTen database without using aggregate persistence, use a different server DSN and edit the three parameters as follows:

      • CkptFrequency=30

      • CkptLogVolume=0

      • CkptRate=0
