Update an Oracle WebLogic Installation from 7.12 to 7.13
The following steps describe how to update the Camunda artifacts on an Oracle WebLogic application server in a shared process engine setting. For the entire procedure, refer to the update guide. If not already done, make sure to download the Camunda 7.13 Oracle WebLogic distribution.
The update procedure takes the following steps:
- Uninstall the Camunda Applications and Archives
- Replace Camunda Core Libraries
- Replace Optional Camunda Dependencies
- Maintain the Camunda 7 Configuration
- Install the Camunda Archive
- Install the Web Applications
In each of the following steps, the identifier $*_VERSION
refers to the current versions and the new versions of the artifacts.
1. Uninstall the Camunda Applications and Archives
First, uninstall the Camunda web applications, namely the Camunda REST API (artifact name like camunda-engine-rest
) and the Camunda applications Cockpit, Tasklist, and Admin (artifact name like camunda-webapp
).
Uninstall the Camunda EAR. Its name should be camunda-oracle-weblogic-ear-$PLATFORM_VERSION.ear
.
2. Replace Camunda Core Libraries
After shutting down the server, replace the following libraries in $WLS_DOMAIN_HOME/lib
with their equivalents from $WLS_DISTRIBUTION/modules/lib
:
camunda-engine-$PLATFORM_VERSION.jar
camunda-bpmn-model-$PLATFORM_VERSION.jar
camunda-cmmn-model-$PLATFORM_VERSION.jar
camunda-dmn-model-$PLATFORM_VERSION.jar
camunda-xml-model-$PLATFORM_VERSION.jar
camunda-engine-dmn-$PLATFORM_VERSION.jar
camunda-engine-feel-api-$PLATFORM_VERSION.jar
camunda-engine-feel-juel-$PLATFORM_VERSION.jar
camunda-engine-feel-scala-$PLATFORM_VERSION.jar
camunda-commons-logging-$COMMONS_VERSION.jar
camunda-commons-typed-values-$PLATFORM_VERSION.jar
camunda-commons-utils-$COMMONS_VERSION.jar
camunda-template-engines-freemarker-$TEMPLATE_ENGINES_VERSION.jar
feel-engine-$FEEL_ENGINE_VERSION-scala-shaded.jar
freemarker-$FREEMARKER_VERSION.jar
mybatis-$MYBATIS_VERSION.jar
3. Replace Optional Camunda Dependencies
In addition to the core libraries, there may be optional artifacts in $WLS_DOMAIN_HOME/lib
for LDAP integration, Camunda Spin, and Groovy scripting. If you use any of these extensions, the following update steps apply:
LDAP integration
Copy the following library from $WLS_DISTRIBUTION/modules/lib
to the folder $WLS_DOMAIN_HOME/lib
, if present:
camunda-identity-ldap-$PLATFORM_VERSION.jar
Camunda Connect
Copy the following library from $WLS_DISTRIBUTION/modules/lib
to the folder $WLS_DOMAIN_HOME/lib
, if present:
camunda-connect-core-$CONNECT_VERSION.jar
camunda-connect-connectors-all
and camunda-engine-plugin-connect
are part of the .ear
Camunda Spin
Copy the following library from $WLS_DISTRIBUTION/modules/lib
to the folder $WLS_DOMAIN_HOME/lib
, if present:
camunda-spin-core-$SPIN_VERSION.jar
camunda-spin-dataformat-all
and camunda-engine-plugin-spin
are part of the .ear
4. Maintain the Camunda 7 Configuration
If you have previously replaced the default Camunda 7 configuration by a custom configuration following any of the ways outlined in the deployment descriptor reference, it may be necessary to restore this configuration. This can be done by repeating the configuration replacement steps for the updated platform.
5. Install the Camunda Archive
Install the Camunda EAR, i.e., the file $WLS_DISTRIBUTION/modules/camunda-oracle-weblogic-ear-$PLATFORM_VERSION.ear
.
6. Install the Web Applications
REST API
Deploy the web application $WLS_DISTRIBUTION/webapps/camunda-engine-rest-$PLATFORM_VERSION-wls.war
to your Oracle WebLogic instance.
Cockpit, Tasklist, and Admin
Deploy the web application $WLS_DISTRIBUTION/webapps/camunda-webapp-ee-wls-$PLATFORM_VERSION.war
to your Oracle WebLogic instance.
