Moving Audited Files to a Different Data Volume

If you need to move protected files to a different data volume, follow these steps:

1. Stop any applications that access the files to be moved.

2. Using the FUP DUP command, move the files to the new data volume.

3. Using the FUP ALTER command, set the audit attribute of the new files so that the

files are audited.

4. If you want to be able to recover the files, make an online dump of the files in the

new location.

5. Set your applications so they access the new files in their new location.

6. Restart the applications that were stopped in Step 1.

Make sure your applications are accessing each new file. If they access and

modify the old data file, the new data file is obsolete. If this happens, repeat the

procedure.

7. When you are satisfied that your applications are accessing the new files, purge

the old files.

Controlling Transaction Processing

Occasionally, you may have to interrupt the normal flow of TMF operations by

manipulating when or for how long transactions are processed. This section describes

the situations that may require your intervention, and how to manage each situation.

You must be a member of the super user group to issue the TMFCOM commands

described in this section (see the TMF Reference Manual for instructions on using

these commands).

Delaying Transaction Processing

Normally, transaction processing can begin immediately after TMF is started. In certain

situations, you might want to start TMF, but prevent application programs from

beginning transaction processing. For example, before starting transaction processing,

you might want to:

•

Allow volume recovery to run.

•

Check the success of a volume recovery.

•

Complete an online dump, so that transaction processing performance is not

affected.

To delay transaction processing, issue the START TMF command with the DISABLE

BEGINTRANS option:

TMF 10> START TMF, DISABLE BEGINTRANS
