Administration Guide

Domain Server - Show Status

Use the STA command to display the status of the administration server or a managed server.

Open a terminal session on the STA server, and log in as the Oracle user.
Display the status of the domain server:
```
$ STA status [server]
```
Where the [server] is one of the following options:
- staweblogic
- staadapter
- staengine
- staui
For example:
```
$ STA status staengine
```
If the server is running normally, you would see:
```
[server] service is running
 .... and the deployed application for [server] is in an ACTIVE state
```
If the server is not running, you would see:
```
[server] service is shutdown
```
If the domain server is not running, try restarting the STA applications. See Stop the STA Application and Restart the STA Application.

Caution:

Do not start or stop individual STA domain servers, unless directed to by Oracle Service.

About the TBI Domain Servers

The following are the TBI domain servers and the processes they control.

Administration server (staweblogic)—Control entity for the TBI domain; provides all security mechanisms.
Managed servers:
- staadapter—SNMP communication with the libraries; stores data received from the libraries.
- staengine—Transforms data from the staadapter for the STA database.
- staui—STA user interface

The administration server (staweblogic) must be running before the managed servers can be started. When the managed servers start, they contact the administration server for their configuration information. Once they are up and running, if the administration server becomes unavailable, the managed servers continue to run uninterrupted.
