Blue screen displays when logging in to the application



A blue screen displays when logging in to the application.

Error Messages][STACK][ Cannot restore passivated page 'pyPortal' for Thread

Steps to Reproduce

  1. Log in to application.
  2. Allow the session to passivate.
  3. Re-log in to the application.

Root Cause

A defect or configuration issue in the operating environment.

The passivated Requestors and corresponding pages were not cleaned. There were entries in both the tables which dated back to January. The large backlog resulted in a Delete from the pr_page_store, to timeout. Hence, some of the pages were deleted. However, the corresponding requestors from pr_sys_context were still in the table.


Perform the following local-change:
  1. Truncate the below tables to cleanup the backlog of the expired passivated requestors.

    - pr_page_store
    - pr_sys_context table

  2. Ensure that the ClusterAndDBCleaner agent is running on one node and the tables are cleaned regularly.
