Hola, un día me enfrente a la siguiente situación: Instale un agente de Cloud Control en la ruta equivocada.
Y se nos viene la idea, fácil, lo remueve y lo reinstalo.
Esto podrá ser fácil, pero si puede complicarse si la red es lenta, es un sitio remoto, etc etc.
Y si existe una forma mas fácil, porque no la ejecutamos?, bueno aquí veremos algo que para mi criterio resulta, más fácil.
Usaremos el DOCID:
Que nos provee el script:
ConvertToStandalone.pl
Hay que tener algunas consideraciones con la nota, hay que definir estas 2 variables de SO:
El Home no es el agent_inst es el $OH/core/Version12c
export OLD_AGENT_HOME=/oracle/agent12c/core/12.1.0.5.0
export ORACLE_HOME=/oracle/agent12c/core/12.1.0.5.0
Generamos el plugin list
$OLD_AGENT_HOME/perl/bin/perl /tfs/oracle/agent12c/core/12.1.0.5.0/sysman/install/create_plugin_list.pl -instancehome /tfs/oracle/agent12c/core/12.1.0.5.0 The agent Base Dir is /oracle/agent12c
Creating file : /oracle/agent12c/rwFile
Removed the /oracle/agent12c/rwFile file.

Modifying the oragchomelist to include the current agent home with the instancehome
The migration is completed Successfully. Run /home/oracle/agent12c/core/12.1.0.5.0/root.sh as root user manually.
Deinstall agent home /oracle/agent12c/core/12.1.0.5.0 manually.
[oracle@nodo ~]$ exit
logout
Ejecutamos el script de root de nuevo:
[root@nodo ~]# /home/oracle/agent12c/core/12.1.0.5.0/root.sh
Con esto el agente de movio de folder a un nuevo directorio.
Espero les sea de Utilidad
Saludos
