3 Migrate Clustered WebCenter Content 11g to New Hosts on an Identical or Dissimilar Infrastructure
Topics that follow will guide you in moving clusters of WebCenter Content 11g to another infrastructure where Operating System and directory structure may or may not be the same as the existing infrastructure.
Note:
The versions of WebLogic Server and WebCenter Content must match between the old hosts and the new hosts. The following topics DO NOT include instructions for upgrading to a newer version but for migrating current setup of WebCenter Content. To migrate other Oracle products from the existing infrastructure such as WebCenter Portal or BPM, make sure to take in account the required instructions. These topics focus only on migrating WebCenter Content.Topics

3.1 Preliminary Steps Before Migrating Clustered WebCenter Content Release 11g
- Stop all managed servers, the admin server, and the node manager
- Back up WebCenter Content file system.
- Back up WebCenter Content's database.
- Install the same JDK version on the new host as the one on the old host
- Install WebLogic Server's binaries on the new host.
- Install WebCenter Content's binaries on the new host.
- Install the same patches on the new host as were applied to the old host.
- If WebCenter Content is being migrated, detach/unmount the shared file system from the old hosts.
- If WebCenter Content is being cloned, detach/unmount the shared file system from the old hosts and also copy the shared file system to its new location.
- There are a few scenarios in which the database will be moving as well. One
such scenario is when WebCenter Content is moving to the Oracle Cloud. A second
scenario is when the database is moving to a new infrastructure for an
on-premise migration. A third scenario could be that WebCenter Content is being
cloned. In any of these cases, the database schemas are assumed to be available
in their new database instance and reachable from the new hosts on which
WebCenter Content will reside. When the Configuration Wizard
(
config.sh
) is run, additional steps will need to be taken to ensure connectivity to the database schemas in their new location.There are three objects within the system schema that are required for Fusion Middleware to operate properly, especially when it comes to upgrades. These objects are: schema_version_registry view, schema_version_registry synonym, and schema_version_registry$ table. If any of these items are missed, you must follow the steps in Recover Lost RCU Database SYSTEM.SCHEMA_VERSION_REGISTRY Objects to recreate the missing objects in the new database instance to prevent issues in the future. In addition to that, you must also include all of the schemas whose names contain the prefix that you defined for the environment in question.
3.2 Recover Lost RCU Database SYSTEM.SCHEMA_VERSION_REGISTRY Objects
The SYSTEM.SCHEMA_VERSION_REGISTRY
schema version registry
table contains version data for all the schemas. Many operations such as upgrade cannot
proceed if this table is not available.
3.3 Build a Template for an Existing Domain
After you've performed the preliminary steps, build a template for the domain you plan to migrate.
3.4 Create a New Domain
You've created the domain template and copied it to the new host to which you are migrating your WebCenter Content instance. Now create a new domain on the new host.
3.5 Copy WebCenter Content Directory to the New Host
Now that the domain is created, go ahead and copy the WebCenter
Content directory to the new host. Several tools are available to help you
accomplish this task. In this example, we'll use rsync
to copy from
one Linux host to another.
3.6 Disable Host Name Verification
- Start the admin server on the target host (in this example,
apphost1
) and wait until the status shows as RUNNING. - Login to the Admin Server console. If running in production mode, click Lock & Edit in the Change Center.
- Go to Environment > Servers > AdminServer(admin).
- Click the SSL tab, then click Advanced.
- Set Hostname Verification to None and click Save.
- Go to Environment >
Servers > your
WebCenter Content server 1 (In this
example,
UCM_server1
). - Click the SSL tab and then click Advanced.
- Confirm Hostname Verification is set to None and click Save.
- Go to Environment >
Servers > your
WebCenter Content server 2
(In this example,
UCM_server 2
). - Click the SSL tab and then click Advanced.
- Confirm Hostname Verification is set to None and click Save.
- Go to Environment >
Servers > Oracle
Inbound Refinery 1 (in this example,
IBR_server1
). - Click the SSL tab and then click Advanced.
- Confirm Hostname Verification is set to None and click Save.
- Go to Environment >
Servers > Oracle
Inbound Refinery 2 (in this example,
IBR_server2
). - Click the SSL tab and click Advanced.
- Confirm Hostname Verification is set to None and click Save.
- If running in production mode, click Activate Changes in the Change Center.
3.7 Mount Shared File System and Adjust Configuration Settings for WebCenter Content
If WebCenter Content was migrated, mount the shared file system at this time. Instead, if it was cloned, mount the shared file system from the new location at this time.
3.8 Verify that WebCenter Content 1 (UCM_server1) Starts on the New Host
- On the target cluster, start the node manager on
apphost1
. - In the Domain Structure, go to Environment > Servers.
- On the Control tab, select the check box for WebCenter
Content 1 (in this example,
UCM_server1
). - Click Start and then Yes to confirm.
- Above the Servers table, click the refresh arrow and note that UCM_server1's state changes to RUNNING.
- Open a browser and confirm that the
portal.htm
on the newapphost1
host loads successfully.
3.10 Copy WebCenter Content Directory to the New Host
Several tools are available to help you copy the WebCenter Content directory
to the new host. In this example, we'll use rsync
to copy from one
Linux host to another.
3.11 Adjust Configuration Settings for the WebCenter Content Node
3.12 Verify that UCM_server2 Starts on the New Host
- On the target cluster, on
apphost1
, start the admin server. - On the target cluster, on
apphost2
, start the node manager. - In the Domain Structure, go to Environment > Servers.
- On the Control tab, select the check box for UCM_server2.
- Click Start, then click Yes to confirm.
- Above the Servers table, click the
refresh arrow. Observe that
UCM_server2
’s state changes to RUNNING. - Open a browser and confirm that the
portal.htm
on the newapphost2
host loads successfully. - From the existing Administration Console browser tab, go to Environment > Servers.
- On the Control tab, select the check box for UCM_server2.
- Click Shutdown/Force Shutdown (If Force is not used, running state issues will be experienced.)
- Click Yes to confirm.
- Above the Servers table, click the refresh arrow. Observe that UCM_server2’s state changes to SHUTDOWN.
3.14 Verify that Inbound Refineries Start Successfully on New Hosts
- In the Domain Structure, go to Environment > Servers.
- On the Control tab, select the check boxes for IBR_server1 and IBR_server2.
- Click Start and then Yes to confirm.
- Above the Servers table, click the
refresh arrows. Observe that
the state of
IBR_server1
andIBR_server2
changes to RUNNING. - Confirm that you can log in successfully to both refineries.
