Creating a journal definition - assure_mimix - 10.0

Do the following to create a journal definition:

1. From the MIMIX Basic Main Menu, type an 11 (Configuration menu) and press Enter.

2. From the MIMIX Configuration Menu select option 3 (Work with journal definitions) and press Enter.

3. The Work with Journal Definitions display appears. Type 1 (Create) next to the blank line at the top of the list area and press Enter.

4. The Create Journal Definition display appears. At the Journal definition prompts, specify a two-part name.

5. Verify that the following prompts contain the values that you want. If you have not journaled before, the default values are appropriate. If you need to identify an existing journaling environment to MIMIX, specify the information you need.

   Journal   Library

   Journal library ASP

   Journal receiver prefix    Library

   Journal receiver library ASP

6. At the Target journal state prompt, specify the requested status of the target journal. The shipped default value, *ACTIVE, is required for target journal inspection. The value *ACTIVE can be used with active journaling support or journal standby state.

   Note: Journal standby state requires the IBM feature for High Availability Journal Performance. For more information see Configuring for high availability journal performance enhancements.

7. At the Target journal inspection prompt, the shipped default value, *YES, allows the specified journal to be inspected for activity by users or programs other than MIMIX. Inspection occurs at the journal level when the system on which the specified journal exists is the target system for replication by one or more enabled data groups. To prevent journal inspection, specify *NO.

8. At the Journal caching prompt, the shipped default value, *NONE, prevents caching of journals in main storage before writing them to disk which is only possible if a separate, chargeable feature from IBM (Option 42) is available on the system. To use journal caching on both systems, only the source system, or only the target system, specify *BOTH, *SRC, or *TGT.

   Note: Journal caching requires the IBM feature for High Availability Journal Performance. For more information see Configuring for high availability journal performance enhancements.

9. Set the values you need to manage changing journal receivers, as follows:

   1. At the Receiver change management prompt, specify the value you want. The default values are recommended. For more information about valid combinations of values, press F1 (Help).

   2. Press Enter.

   3. One or more additional prompts related to receiver change management appear on the display. Verify that the values shown are what you want and, if necessary, change the values.

      Receiver threshold size (MB)

      Time of day to change receiver

      Reset large sequence threshold

   4. Press Enter.

10. Set the values you need to manage deleting journal receivers, as follows:

    1. It is recommended that you accept the default value *YES for the Receiver delete management prompt to allow MIMIX to perform delete management.

    2. Press Enter.

    3. One or more additional prompts related to receiver delete management appear on the display. If necessary, change the values.

       Keep unsaved journal receivers

       Keep journal receiver count

       Keep journal receivers (days)

11. At the Description prompt, type a brief text description of the journal definition.

12. This step is optional. If you want to access additional parameters that are considered advanced functions, press F10 (Additional parameters). Make any changes you need to the additional prompts that appear on the display.

13. To create the journal definition, press Enter.
