Enabling and Disabling PowerCenter Integration Services and Processes
You can enable and disable a PowerCenter Integration Service process or the entire PowerCenter Integration Service. If you run the PowerCenter Integration Service on a grid or with the high availability option, you have one PowerCenter Integration Service process configured for each node. For a grid, the PowerCenter Integration Service runs all enabled PowerCenter Integration Service processes. With high availability, the PowerCenter Integration Service runs the PowerCenter Integration Service process on the primary node.
Enabling or Disabling a PowerCenter Integration Service Process
Use the Administrator tool to enable and disable a PowerCenter Integration Service process. Each service process runs on one node. You must enable the PowerCenter Integration Service process if you want the node to perform PowerCenter Integration Service tasks. You may want to disable the service process on a node to perform maintenance on that node or to enable safe mode for the PowerCenter Integration Service.
To enable or disable a PowerCenter Integration Service process:
1. In the Administrator tool, click the Manage tab > Services and Nodes view.
2. In the Domain Navigator, select the PowerCenter Integration Service.
3. In the contents panel, click the Processes view.
4. Select a process.
5. To disable a process, click Actions > Disable Process.
The Disable Process dialog box displays.
6. Choose a disable mode, and then click OK.
7. To enable a process, click Actions > Enable Process.
Enabling or Disabling the PowerCenter Integration Service
Use the Administrator tool to enable and disable a PowerCenter Integration Service. You may want to disable a PowerCenter Integration Service if you need to perform maintenance or if you want temporarily restrict users from using the service. You can enable a disabled PowerCenter Integration Service to make it available again.
When you disable the PowerCenter Integration Service, you shut down the PowerCenter Integration Service and disable all service processes for the PowerCenter Integration Service. If you are running a PowerCenter Integration Service on a grid, you disable all service processes on the grid.
When you disable the PowerCenter Integration Service, you must choose what to do if a process or workflow is running. You must choose one of the following options:
- •Complete. Allows the sessions and workflows to run to completion before shutting down the service.
- •Stop. Stops all sessions and workflows and then shuts down the service.
- •Abort. Tries to stop all sessions and workflows before aborting them and shutting down the service.
When you enable the PowerCenter Integration Service, the service starts. The associated PowerCenter Repository Service must be started before you can enable the PowerCenter Integration Service. If you enable a PowerCenter Integration Service when the associated PowerCenter Repository Service is not running, the following error appears:
The Service Manager could not start the service due to the following error: [DOM_10076] Unable to enable service [<Integration Service] because of dependent services [<PowerCenter Repository Service>] are not initialized.
If the PowerCenter Integration Service is unable to start, the Service Manager keeps trying to start the service until it reaches the maximum restart attempts defined in the domain properties. For example, if you try to start the PowerCenter Integration Service without specifying the code page for each PowerCenter Integration Service process, the domain tries to start the service. The service does not start without specifying a valid code page for each PowerCenter Integration Service process. The domain keeps trying to start the service until it reaches the maximum number of attempts.
If the service fails to start, review the logs for this PowerCenter Integration Service to determine the reason for failure and fix the problem. After you fix the problem, you must disable and re-enable the PowerCenter Integration Service to start it.
To enable or disable a PowerCenter Integration Service:
1. In the Administrator tool, click the Manage tab > Services and Nodes view.
2. In the Domain Navigator, select the PowerCenter Integration Service.
3. On the Manage tab Actions menu, select Disable Service to disable the service or select Enable Service to enable the service.
4. To disable and immediately enable the PowerCenter Integration Service, select Recycle.
