Manage remote journals

Managing the remote journal function requires basic tasks such as:

• Keeping records of your remote journal network.
• Evaluating the impact on the remote journal network as new applications are added or the system workload grows.
• Considering the ramifications of journal receivers on two systems which require regular save and delete processing.
• Considering the save and restore implications of the remote journal network.

The following information describes the management tasks for remote journals:

• Keep records of your remote journal network
  Always have a current list of the remote journals that are associated with local journals, and their associated communications information.
• Display remote journal function information
  When you are working with the remote journal function, you will want to be able to view the remote journal network. You may also want to view the various attributes, journal states, or delivery modes.
• Evaluate how system changes affect your remote journal network
  After you have initially established your remote journal network, you need to keep up with changes that occur on the system.
• Get information about remote journal entries
  Working with the journal entries in a remote journal is essentially the same as working with the journal entries in a local journal.
• Journal receiver management with remote journals
  As with local journals, regularly save and delete your journal receivers to minimize the amount of online auxiliary storage which is used by the journal receivers.
• Swap journal receiver operations with remote journals
  To swap journal receivers on a remote journal, perform a swap journal receiver operation on the source system to attach a new receiver to a local journal. When this happens, the remote journal function automatically attaches a new receiver to the remote journals that are currently being maintained synchronously or asynchronously.
• Considerations for save and restore operations with remote journals
  The following information describes general considerations for save and restore operations with remote journals:
• Remote journal considerations when restarting the server
  This topic discusses the considerations for remote journaling when you restart the server.
• Work with remote journal error messages
  Several different error conditions can occur when the remote journal function is active.
