Introducción
Grid Control se compone de una serie de servicios, cada uno de los cuales está instalado en su propio HOME y que pueden y deben ser manejados separadamente. El objetivo de este manual es presentar de manera concreta los comandos necesarios para levantar, detener y monitorear todos estos servicios. Las partes correspondientes a levantar y detener los servicios deben ejecutarse en el orden indicado.
Variables de ambiente
Es recomendable definir las siguientes variables de ambiente:
# Variables de ambiente para Grid Control
OMS_HOME=/opt/oracle/OracleHomes/oms10g
export OMS_HOME
AGENT_HOME=/opt/oracle/OracleHomes/agent10g
export AGENT_HOME
ORACLE_HOME=/opt/oracle/OracleHomes/db10g
export ORACLE_HOME
ORACLE_SID=emrep
export ORACLE_SID
PATH=$PATH:$OMS_HOME/bin:$AGENT_HOME/bin:$ORACLE_HOME/bin:$OMS_HOME/opmn/bin
export PATH
En este caso se asume que la instalación de Grid Control se hizo en el directorio /opt/oracle, en caso de encontrarse en una ubicación diferente, realizar los cambios necesarios en las variables de ambiente.
Levantar todos los servicios
1. Levantar el listener:
$ $ORACLE_HOME/bin/lsnrctl start
2. Levantar la base de datos:
$ $ORACLE_HOME/bin/sqlplus /nolog
SQL> connect SYS as SYSDBA
SQL> startup
SQL> quit
3. Levantar OMS (Oracle Management Service):
$ $OMS_HOME/bin/emctl start oms
4. Levantar todos los componentes de Application Server (web cache, http server):
$ $OMS_HOME/opmn/bin/opmnctl startall
5. Levantar el agente:
$ $AGENT_HOME/bin/emctl start agent
6. (Opcional) Levantar el Application Server Control Console:
$ $OMS_HOME/bin/emctl start iasconsole
Detener todos los servicios
1. Detener el OMS:
$ $OMS_HOME/bin/emctl stop oms
2. Detener, si está arriba, el Application Server Control Console:
$ $OMS_HOME/bin/emctl stop iasconsole
3. Detener todos los componentes del Application Server (http server, web cache, etc.):
$ $OMS_HOME/opmn/bin/opmnctl stopall
4. Detener el agente:
$ $AGENT_HOME/bin/emctl stop agent
5. Detener la base de datos
$ $ORACLE_HOME/bin/sqlplus /nolog
SQL> connect SYS as SYSDBA
SQL> shutdown
SQL> quit
6. Detener el listener:
$ $ORACLE_HOME/bin/lsnrctl stop
Monitorear los servicios
Agente:
$AGENT_HOME/bin/emctl status agent
OMS (Oracle Management Service):
$ $OMS_HOME/bin/emctl status oms
Componentes de Application Server:
$ $OMS_HOME/opmn/bin/opmnctl status
Detener OCSSD.BIN
El proceso $ORACLE_HOME/bin/ocssd.bin se levanta automáticamente como parte de la instalación de RDBMS incluida en Grid Control. Dicho proceso no requiere administración alguna, sin embargo, de ser necesario detenerlo (generalmente durante la aplicación de parches), el proceso correcto para hacerlo es (con el usuario root):
# /etc/init.d/init.cssd stop
$AGENT_HOME/sysman/emd/state
export AGENT_HOME=/opt/oracle/product/agent10g/
echo $AGENT_HOME
rm –Rf $AGENT_HOME/sysman/emd/upload/*.*
rm –Rf $AGENT_HOME/sysman/emd/state/*.*
$ ./emctl clearstate agent
$ ./emctl unsecure agent
$ ./emctl start agent
$ ./emctl upload agent
$ ./emctl secure agent
OTROS COMANDOS
This document will detail the steps required to stop and start Oracle Enterprise Manager 11g Grid Control and all its components. For information on installing Oracle Enterprise Manager 11g Grid Control see the post Install Oracle Enterprise Manager Grid Control 11gR1 on Linux.
In this document I will be making references to the
OMS_HOME and
AGENT_HOME. If you do not happen to
know what those locations are you can find them in the /etc/oratab
file.|

[oracle@gc bin]$
grep -E 'oms|agent' /etc/oratab *:/u02/app/oracle/product/weblogic/oms11g:N *:/u02/app/oracle/product/weblogic/agent11g:N [oracle@gc
bin]$ |
So in this example the
OMS_HOME would be
/u02/app/oracle/product/weblogic/oms11g and AGENT_HOME would be
/u02/app/oracle/product/weblogic/agent11g.NOTE: The Oracle Enterprise Manger 11g Grid Control install process puts a script called
gcstartup in
/etc/init.d that will stop and start the Oracle Management Service
and Agent on OS startup/shutdown. It does not start or stop the repository database. If you would
like to stop the automated startup/shutdown of Grid
Control services place comments in front of the
OMS and AGENT home directories in the /etc/oratab file or remove
the script /etc/init.d/gcstartup.

From the
OMS_HOME directory run the following to stop the OMS and WebTier services.|
