Changing the LTPA Keys

This procedure describes how to change the LTPA key. The LTPA key is shared among all cells in the patterns. It is not used in the SOA Policy Gateway Basic Runtime Sample pattern. The LTPA Key is exported from the Governance Master and imported into runtime environments, such as staging or production.

Procedure

  1. Export the new LTPA Key from the Governance Master WSRR Dmgr.
  2. Import the LTPA Key into the Runtime WSRR instances, which are Dmgr or Stand Alone.
  3. If the Runtime instance is based on an advanced runtime pattern, complete the following in order:
    1. Synchronize all nodes.
    2. Stop the WSRR Cluster.
    3. Stop the node agents.
    4. Stop the Dmgr.
  4. If the WSRR system is based on an advanced runtime pattern, it must be restarted in reverse order:
    1. Start the Dmgr.
    2. Start the node agents.
    3. Start the WSRR Cluster.
  5. If the WSRR is a Standalone Server (based on a basic runtime pattern), it must be stopped and restarted for the LTPA Key change to take effect.
