Enable and Disable Metadata Access Services and Processes
You can enable and disable the entire Metadata Access Service or a single Metadata Access Service process on a particular node.
If you run the Metadata Access Service with the high availability option, you have one Metadata Access Service process configured for each node. For high availability, the Metadata Access Service runs the Metadata Access Service process on the primary node.
Enable Disable or Recycle the Metadata Access Service
You can enable, disable, or recycle the Metadata Access Service. You might disable the Metadata Access Service if you need to perform maintenance or you need to temporarily restrict users from using the service. You might recycle the service if you changed a service property or if you updated the role for a node assigned to the service.
The number of service processes that start when you enable the Metadata Access Service depends on the following components which the service can run on:
- Single node
- When you enable a Metadata Access Service that runs on a single node, a service process starts on the node.
- Primary and back-up nodes
- When you enable a Metadata Access Service configured to run on primary and back-up nodes, a service process is available to run on each node, but only the service process on the primary node starts. For example, you have the high availability option and you configure a Metadata Access Service to run on a primary node and two back-up nodes. You enable the Metadata Access Service, which enables a service process on each of the three nodes. A single process runs on the primary node, and the other processes on the back-up nodes maintain standby status.
When you disable the Metadata Access Service, you shut down the Metadata Access Service and disable all service processes.
When you recycle the Metadata Access Service, the Service Manager restarts the service.
Enabling, Disabling, or Recycling the Service
You can enable, disable, or recycle the service from the Administrator tool.
1. In the Administrator tool, click the Manage tab > Services and Nodes view.
2. In the Domain Navigator, select the service.
3. On the Manage tab Actions menu, click one of the following options:
- - Enable Service to enable the service.
- - Disable Service to disable the service. Choose the mode to disable the service in.
Disable Mode | Description |
|---|
Abort | Abruptly kills the service. |
Complete | Waits for all the sessions to complete and then, stops the service. |
Stop | Stops the service after a grace period of 30 seconds. Applicable only for Metadata Access Service. |
If you complete these options, the information appears in the Events and Command History panels in the Domain view on the Manage tab.
- - Recycle Service to recycle the service.
Enable or Disable a Metadata Access Service Process
You can enable or disable a Metadata Access Service process on a particular node.
The impact on the Metadata Access Service after you disable a service process depends on the following components which the service can run on:
- Single node
- When the Metadata Access Service runs on a single node, disabling the service process disables the service.
- Primary and back-up nodes
- When you have the high availability option and you configure the Metadata Access Service to run on primary and back-up nodes, disabling a service process does not disable the service. Disabling a service process that is running causes the service to fail over to another node.
