What's new for IBM® i 7.1

Describes the improvements and additions to journal management.

Object name filtering ability for automatic journaling

When journaling libraries by using the Start Journal Library (STRJRNLIB) command you can now select or omit objects to automatically start journaling based on the name of the object. This allows the ability to automatically start journaling new production files in the library, but not journal temporary work files if they are named uniquely.

See these items for more information:

New journal entry types for journal entry codes I and Q

For journal code I - Internal operation, there is a new entry type, IK - Access path protection.

For journal code Q - Data queue operation, there is a new entry type, QF - Change journal object attribute.

For a list of all journal entries by code and type see: All journal entries by code and type

Additional journal entries supported by the Replay Journal Entry (QjoReplayJournalEntry) API

The Replay Journal Entry (QjoReplayJournalEntry) API can now be used to replay the dequeue entries for data queues.

See the Replay Journal Entry (QjoReplayJournalEntry) API for more information.

Additional journal management functions with IBM Navigator for i

IBM Systems Director Navigator now supports additional journal management functions. With i 7.1 the following functions were all added:
  1. The ability to change journal receivers and attributes associated with a journal.
  2. The ability to see the properties associated with a journal receiver.
  3. The ability to see objects journaled to a specific journal.
  4. The ability to add and remove remote journals.
  5. The ability to see the list of remote journals associated with a specific journal.
  6. The ability to activate and inactivate remote journals.
  7. The ability to view the details of a remote journal connection.

Additional details provided for System-managed access-path protection

Additional details are available for System-managed access-path protection (SMAPP) to provide essential information when there are concerns with the impact SMAPP is having on a system.

See the Effects of SMAPP on performance and storage topic for details.

Automatic restart capability with remote journaling

Remote journaling is dependent on communication networks, these networks occasionally have problems. When communication problems are encountered remote journaling ends. New this release is the capability to have remote journaling automatically restart when it ends because of a recoverable error.

Filtering capabilities with remote journal

Historically a remote journal receiver has been a duplicate of the journal receiver associated with the local journal. New this release is the ability to filter entries for a remote journal connection. Filtering out journal entries that are not absolutely needed on the target system can decrease the amount of data sent across the communication line.

Additional detail information with remote journal

In a previous release, function was added to allow you to view how far the source system is behind in sending entries to a target remote journal. New in i 7.1 is the ability from the target side to see how many seconds it is behind in receiving journal entries from the source system. Also new in i 7.1 is the ability from the source side to view the number of retransmissions occurring for a remote journal connection.

See the Work with Journal Attributes (WRKJRNA) command for further information.
