Weblogic server 运行状态是: ADMIN
Here we are going to see a Scenario which is very common but troublesome. Many times we observe that while trying to restart the Managed Servers the Servers move to ADMIN State rather than moving to the RUNNING State. This usually happens If it is unable to activate some of the Modules which are deployed on this Server. usually it happens If any Application is Not getting activated properly or a Datasource or JTA recovery or a JMS System / SubSystem is not getting activated properly then also it moves into the Admin State. So To find out the Root cause we need to keenly observer the Logs. Specially we need to check what configuration changes we made on the Server recently.

Most Probable Cause: Most of the cases it happens if any of the Database is down and WebLogic tries to create the Connection Pool at the boot up time. One way to avoid this kind of scenario is to set the InitialCapacity of the DataSource to 0 (Zero) so that weblogic will not try to create any JDBC Connection object at the start up time so like this we can avoid Connection creation failure conditions and avoid moving our server to ADMIN State.

NOTE: We have an option to forcibily move our WLS Server to the RUNNING State (from ADMIN State) which works almost 80% cases….Still it is must that we find the root cause of Why the Server is moving to ADMIN State. So please consider this article as a Workaround …And not as a solution. Because even if we can bring our server in RUNNING state …still we have to find out why the Server Moved to ADMIN State.

In this Demonstration we will see a simple WLST script which will check if any of the server present inside Domain is in ADMIN State or not? If YES then it will try to force them to move to RUNNING State.

Step1). Create a Directory somewhere in your file system like : “C:\WLST_AdminStateCheck”

Step2). Write a Properties file “domain.properties” inside “C:\WLST_AdminStateCheck” like following:
