Session Data Seems To Be Corrupted

Description

Session data may be corrupted if the system log reports errors under the following circumstances:

• During session persistence

• When the session state is read during session activation

• When the session state is read after session failover

  If the data has been corrupted, there are three possible solutions for bringing the session store back to a consistent state, as described below.

Solution 1

Use the asadmin clear-session-store command to clear the session store.

Solution 2

If clearing the session store does not work, reinitialize the data space on all the nodes and clear the data in the HADB using the hadbm clear command.

Solution 3

If clearing the HADB does not work, delete and then recreate the database.

For solutions 2 and 3, above, after clearing the HADB, recreate the session store to restablish the database schema.
