Todos Sabemos que não é possível subir o Admin Server em Cluster, mas se ele for configurado corretamente, poderá ser iniciado iniciado em qualquer nó.
O erro que mais ocorre quando tentamos subir o Admin Server em outro Nó do Cluster é:
1. weblogic.security.SecurityInitializationException: Authentication for user weblogic denied. 2. java.lang.IllegalStateException: Unable to perform operation: post construct on weblogic.security.SecurityService 3. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of weblogic.jndi.internal.RemoteNamingService errors were found 4. java.lang.IllegalStateException: Unable to perform operation: resolve on weblogic.jndi.internal.RemoteNamingService 5. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of weblogic.connector.common.ConnectorServiceActivator errors were found 6. java.lang.IllegalStateException: Unable to perform operation: resolve on weblogic.connector.common.ConnectorServiceActivator A MultiException has 6 exceptions. They are: 1. weblogic.security.SecurityInitializationException: Authentication for user weblogic denied. 2. java.lang.IllegalStateException: Unable to perform operation: post construct on weblogic.security.SecurityService 3. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of weblogic.jndi.internal.RemoteNamingService errors were found 4. java.lang.IllegalStateException: Unable to perform operation: resolve on weblogic.jndi.internal.RemoteNamingService 5. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of weblogic.connector.common.ConnectorServiceActivator errors were found 6. java.lang.IllegalStateException: Unable to perform operation: resolve on weblogic.connector.common.ConnectorServiceActivator
Isso ocorre devido as credencias do Admin Server não estarem corretas nos outros Nós.
Para solucionar o problem existe uma saídas simples, copiar a pasta data do Admin Server existente em outros servidores, caso se a maquina que contia inicialmente o admin service esteja down, Pode ser copiado a pasta data de qualquer Manager Server existente.
Ex:
cp -r data /u02/middleware/oracle/config/domains/osb_domain/servers/AdminServer/
