The composite revision purge will undeploy specific revisions based on the "Composite Revisions to Keep" Target property, defaulted to 1.  The retained revisions will start at the default revision and retain composites until the property value is met.  If there are more recent revisions than the default revision, those recent revisions will also be retained but will not count against the property value.  Default revision is bold and Composite Revisions to Keep is 2.

In addition, the Preview Mode for Purge input can activate the preview feature that will show the revisions that would have been purged in the logs.  No purge will occur in preview mode.

Configuration plans are used to automatically cleanup environment specific information in a composite.xml file during deployment. Information that can be changed includes URL hosts and retry values, to name a few items. Configuration plans can utilize property replacement to utilize FlexDeploy properties.  Utilizing FlexDeploy properties allows configuration plans to become re-usable.

Composite specific configuration plans that were captured during build in configPlans sub-folder, are available during deploy step along with SCA Jar file.

Configuration plan can be specified using SOA Deploy Config Plan project property and/or Deploy Config Plan plugin input. The plugin input will take precedence over the project property. Deploy Config Plan input can be either an absolute path to a global configuration plan or composite configuration plans file name. Composite configuration plans are placed in FD_TEMP_DIR by FlexDeploy SOA Plugin (from configPlans artifact directory), so you do not need to qualify it, just provide name when using composite specific configuration plans.

There are two approaches to Configuration Plans:

Shared (recommended method)

A shared configuration plan provides the same functionality as a composite specific configuration plan but with the added benefit of not needing to remember to generate a configuration plan for new composites or new environments.  The shared configuration plan will be managed seperately from the composites and deployed independently to a common location on the servers.  With a shared configuration plan, utilizing FlexDeploy property replacement is a must.  Shared configuration files can be either environment specific or global across all environments due to the use of property replacement.

You will notice that in the import section of the conguration plan, any host name is being replaced with a string "change to mds ref".  The reason is that when leveraging MDS or relative paths for XSDs or abstract WSDLs, there should be no references to the server.  When a developer forgets to clean up the composite correctly, this helps to remind them because the deploy will fail with a message that includes the string above.

There may be other properties that need to be replaced based on your organization, which include endpointURI, oracle.webservices.auth.userid and oracle.webservices.auth.password, as examples.  These can be replaced utilizing the same pattern as above.

</SOAConfigPlan>

On the soaDeploy operation used in the deployment workflow, change the FDSOA_INP_DEPLOY_CFG_PLAN input to a groovy expression similar to following if the shared plan is environment specific:

"/shared/location/" + FD_ENVIRONMENT_CODE + "*_cfgplan.xml"

If the shared plan is global, use an expression like: 

"/shared/location/acme_cfgplan.xml"

This will allow the workflow to remain re-usable across all composite deployments even though the configuration plans are specific to a composite.

Composite specific (not recommended because it leads to errors, many files with similar contents)

A composite specific configuration plan is created directly in the composite project using the JDeveloper wizard.  Right click on the composite.xml file and select "Generate Config Plan".  Provide the plan a name and it is recommended that you add the FlexDeploy environment code in the name.  

Composite specific approach will require a configuration plan for each environment for each composite since the goal is to cleanup host names as we progress through environments. The two blocks below show examples of what a configuration plan would look like for a DEV (hard code the host name) and QA (utilizing FlexDeploy property replacement) environment. You can decide to either hard code such values in each environment specific Configuration Plan or you can use FlexDeploy property replacement support.

</SOAConfigPlan>

On the soaDeploy operation used in the deployment workflow, change the FDSOA_INP_DEPLOY_CFG_PLAN input to a groovy expression similar to:

"./" + FD_ENVIRONMENT_CODE + "*_cfgplan.xml".  

This will allow the workflow to remain re-usable across all composite deployments even though the configuration plans are specific to a composite.

All files with the following suffix ("xml", "txt", "wsdl", "bpel", "jca", "xsd", "componentType", "dvm", "xref", "xsl", "wadl", "mplan", "task") within the composite file structure are pre-processed by the plugin to transform any defined replacement properties.

A deployment config plan file or composite.xml will have server host names within it and will vary from environment to environment.
