Fallback step 5: Verify fallback

After you start Db2 12, you must complete some of your own testing to determine if the fallback was successful.

About this task

You cannot run the Db2 13 samples on Db2 12.

Procedure

To verify fallback:

  1. Test the IVP phase 2 applications:
    1. DSNTEJ2A: Perform all except the first two steps of job DSNTEJ2A. Expect a return code of 4 because table spaces DSN8D12U.NEWDEPT and DSN8D12U.NEWPHONE are placed in COPY-pending states.
    2. DSNTEJ2C: Issue only the RUN PROGRAM(DSN8BC3) PLAN(DSN8BH12) statement in step PH02CS04.
    3. DSNTEJ2D: Issue only the RUN PROGRAM(DSN8BD3) PLAN(DSN8BD12) statement in step PH02DS03.
    4. DSNTEJ2E: Issue only the RUN PROGRAM(DSN8BE3) PLAN(DSN8BE12) statement in step PH02ES04.
    5. DSNTEJ2F: Issue only the RUN PROGRAM(DSN8BF3) PLAN(DSN8BF12) statement in step PH02FS03.
    6. DSNTEJ2P: Run only step PH02PS05.
  2. Test the IVP phase 3 applications.
    Do not run job DSNTEJ3C or DSNTEJ3P.
  3. Run the Db2 12 sample applications.
  4. Test your own applications.
  5. Retry the problem for which you decided to fall back.
