Enabling and Disabling Process Model Versions
You can enable or disable webMethods-executed process model versions for execution. Only one version of a process model can be enabled at any time.
When you initially build and upload a process model from Designer, the version is disabled by default. However, you can specify that the process model is automatically enabled during the build and upload process in Designer. Otherwise, you must enable the process in Monitor.
When a model version is disabled, Process Engine will not use the model version for new process instances. If no versions of a process model are enabled, the Process Engine will not start any process instances of the process model.
Important: | If all versions of a model that is called by another process are disabled, the parent process will fail at the step that calls the disabled process model. |
When you enable a model version, if another version was previously enabled,
Monitor disables it, and
Process Engine uses the newly enabled version when starting new process instances. When you enable a new version of a process model, you can optionally upgrade all running process instances that use the model, so that they immediately start using the newer version with the next step to be executed. For additional information, see
Updating a Process Instance to a New Model
Version.
To enable or disable a webMethods-executed model version
1. In My webMethods: Navigate > Applications > Administration > Business > Business Processes.
2. Search for the model version to enable or disable. In the search results, click 
Edit for the model version to open the Edit Process page. 3. Click the Process Details tab and do either of the following:
Select the
Execution Enabled check box to enable the model version.
Monitor asks if you want to upgrade running process instances to this version of the process model so that they immediately start using the newly enabled version with the next step to be executed. If you want to upgrade all running instances of the process model to use the new model version, click Yes.
Clear the
Execution Enabled check box to disable the model version.
4. Click Save.
