Activate and inactivate remote journals

Activating a remote journal means starting and then maintaining the replication of journal entries from a source journal to a remote journal. Activating a remote journal always occurs from the source system.

Inactivating a remote journal means ending the replication of journal entries from the source journal to the remote journal. Inactivating a remote journal can be performed from the source or target systems. However, the preferred method is to inactivate from the source system.

If this is the first time the remote journal is being activated, activating a remote journal creates one or more journal receivers on the target system. Activating the remote journal also establishes the connection between the source and remote journal so that journal entry replication can begin.

If the remote journal has previously been activated, the system may or may not create additional receivers on the target system. This would occur prior to establishing the connection between the source and remote journal so that journal entry replication can resume.

You must be aware if library redirection is in effect for the remote journal when you activate or inactivate a remote journal. If it is in effect, any library name processing will substitute the redirected library name for the library name that is used for the operation on the target system.

See the following for instructions on activating and inactivating remote journals:

• Activate the replication of journal entries to a remote journal
  In order to activate the replication of journal entries to a given remote journal, the following must be true:
• Relational database considerations for remote journal state
  Once a remote journal is activated, the remote journal function will work with the communications configuration defined by the specified relational database (RDB) entry as long as the remote journal is active. However, the information will be taken from the RDB at the point in time when the remote journal was activated. Therefore, even if the definition of the RDB entry is changed while a remote journal has a journal state of *ACTIVE, none of those changes will take effect immediately.
• Inactivate the replication of journal entries to a remote journal
  When you end replication of journal entries to a remote journal, it is recommended that the replication of entries be ended from the source system whenever possible, rather than from the target system. Usually, ending replication from the target system for a remote journal is only necessary when the source system has failed, and the system has not ended the remote journal function.
