6.2.3 Backing up the environment
Before you perform a version upgrade installation, you need to create a backup of the Item management database in the pre-upgrade environment by using the jssdbbackup.bat command. This backup can be used to recover the database if something goes wrong. Specify the -maint argument when executing the jssdbbackup.bat command. For details on the backup procedure, see jssdbbackup.bat (backs up databases) in Chapter 12. Commands. You must also back up the definition information for JP1/Service Support. Specifically, you need to back up every file listed in Table 11-1 in 11.1.1 Backing up definition information, except the environment setup commands, cluster environment setup command, and environment settings files.
If the installation process fails, use the following procedure to restore the pre-installation environment:
-
Uninstall the version of JP1/Service Support that is currently installed.
For details on how to uninstall JP1/Service Support, see 6.7 Unsetup and uninstallation of JP1/Service Support.
-
Delete all the installation folders.
-
Perform a new installation of the same version of JP1/Service Support that was originally installed.
For details on how to install JP1/Service Support, see 6.3.1 New installation procedure.
-
Recover the definition information from the backup.
For details on how to restore definition information, see 11.1.2 Recovering definition information.
-
Set up a new environment.
For details on how to set up the environment for JP1/Service Support, see 6.3.2 Setup procedure for new installation.
-
Restore the pre-upgrade environment by recovering the data you backed up.
For details on how to recover data, see jssdbrecovery.bat (recovers a database) in Chapter 12. Commands.
