Migrate the UDDI registry
With most scenarios, existing UDDI registries are migrated automatically when you migrate to the current level of WAS. However, if your existing UDDI registry uses a network Apache Derby database or a DB2 UDDI v2 database, there are some manual steps that take. Migrate your installation of WAS. Ensure that you select the option to migrate applications, so that the UDDI registry application will be migrated.
If your existing UDDI registry uses an Oracle, embedded Apache Derby or DB2 UDDI Version 3 database, you do not have to complete any manual migration; the registry is migrated automatically when you migrate WAS and start the UDDI node for the first time after migration.
If your existing UDDI registry uses a network Apache Derby database or a DB2 UDDI v2 database, complete some manual steps to migrate the registry.
If the UDDI database uses Apache Derby v10.2, migrate the database. For details, see the topic in the related links.
Procedure
If your UDDI registry uses a network Apache Derby database, complete the following steps.
- If we have a cluster that contains servers at different levels of WAS, ensure that any UDDI registries are running on servers that are at the current level of WAS. For example, if we have a cluster that spans two nodes, you can upgrade one node to the current level while the other node remains at a previous level, provided that any servers that are running a UDDI registry are at the current level.
- Initialize the relevant UDDI node. The initialize process will complete some of the UDDI registry migration.
- Enter the following commands as the database administrator, from WAS_HOME/derby/lib.
java -cp db2j.jar;db2jtools.jar com.ibm.db2j.tools.ij connect 'jdbc:db2j:uddi_derby_database_path'; run 'WAS_HOME/UDDIReg/databaseScripts/uddi30crt_drop_triggers_derby.sql'; quit; cd WAS_HOME/derby/migration java -cp db2j.jar;db2jmigration.jar;../lib/derby.jar com.ibm.db2j.tools.MigrateFrom51 jdbc:db2j:uddi_derby_database_pathwhere
- uddi_derby_database_path is the absolute path of the existing Apache Derby database, for example WAS_HOME/profiles/profile_name/databases/com.ibm.uddi/UDDI30
- WAS_HOME is the root directory for the installation of WAS
Results
The UDDI database and data source are migrated, and the UDDI node is activated.
When you migrate WAS, the post-upgrade log for the profile indicates that the migration of the UDDI database is partially complete, and is missing the steps for triggers, aliases, and stored statements. If you initially enabled the debug function, the debug log for the database indicates that there was a failure creating triggers. Ignore these messages; the UDDI node completes the migration of the database when the UDDI node starts. For more information about these log files, see the topic about verifying the Cloudscape automatic migration. Also refer to this topic if other errors appear in the logs.
If the migration of the UDDI database completes successfully, the following message appears in the server log:
CWUDQ0003I: UDDI registry migration has completedIf the following error appears, an unexpected error occurred during migration. The UDDI registry node is not activated. Check the error logs for the problem and, if you cannot solve it, refer to the problem determination information on the WAS support web page.
