Performing Disaster Recovery

8. The tables for each MS subvolume must be copied from the primary to the backup

system. Before doing this, use FUP SECURE to change the security permissions

of the tables to “nnnn”, Then, use the SQLCI command to copy the tables:

> SQLCI>Dup\primary-system.MS-subvol.??? Where SQL, & >

> \backup-system.MS-subvol.*, &

> Catalog \backup-system.MS-subvol, Saveall

Use FUP SECURE to resecure the tables on both systems.

9. From the primary system, copy to the backup system the DUPL. DUPL0, and

PMMSCSAT files for each MS-subvol.

10. On the backup system, create a file named QFILES in the location

OSIMHS_SUBVOL. Enter the fully-qualified name of all queue files, one name per

line:

vol.subvol.qfile1

vol.subvol.qfile2

vol.subvol.qfile3 ..

11. Run the MHSINST macro on the backup system, specifying the RDF option in

order to audit all database files and fix the alternate key locations.:

> MHSINST RDF

When MHSINST prompts you for the configuration file name, enter the installation

file name as input.

12. On the backup system, start the RDF subsystem. For details, see the Compaq

NonStop™ RDF/IMP and IMPX System Management Manual.

13. On the primary system, restart the OSI/MHS subsystem.

Performing Disaster Recovery

In the event of a primary system failure or planned shutdown, perform the following

tasks to make the backup system take over OSI/MHS operation:

1. Use RDFCOM to perform the complete takeover procedure as described in the

Compaq NonStop™ RDF/IMP and IMPX System Management Manual.

2. Make sure that you have created the file named QFILES in OSIMHS_SUBVOL

and that this file contains the names of all the queue files as entries.

3. Run the PDUDIAG utility and specify the RDF option. Documentation for the

PDUDIAG utility can be obtained from your HP support representative. The

following command syntax example assumes the OSI Manager process has the

name ZHMS. In the PARAM statement, dbvol and dbsubvol specify the volume

and subvolume containing the MHS subsystem group and process database files.

Note. When you specify the RDF option, MHSINST assumes that the alternate key files

reside within the same subvolume as the primary file.
