Managing Your 10g Application Server

Managing the application server primarily the startup and shutdown procedures. I will discuss the opmn tool by Oracle and also the Enterprise Manager

The process described here also holds good for other Oracle products like Oracle Collaboration suite and Oracle SOA suite.

Any application server would necessarily consist of a infrastructure Tier, it may or may not have a middle tier associated.

Starting Application Server Services


Order of Startup

As the middle tier is dependent on your infrastructure it is important that the infrastructure should be up and running before you proceed with the middle tier services.

To start OracleAS Infrastructure:

1. If your OracleAS Infrastructure contains OracleAS Metadata Repository, start it as
follows:

a. Set the ORACLE_HOME environment variable to the OracleAS Infrastructure
Oracle home.

b. Set the ORACLE_SID environment variable to the OracleAS Metadata
Repository SID (default is orcl).

c. Start the Net Listener:

ORACLE_HOME/bin/lsnrctl start

d. Start the OracleAS Metadata Repository instance:

ORACLE_HOME/bin/sqlplus /nolog
SQL> connect SYS as SYSDBA
SQL> startup


SQL> quit


e. Start the Oracle Enterprise Manager 10g Database Control:

(UNIX)ORACLE_HOME/bin/emctl start dbconsole
(Windows)ORACLE_HOME\bin\emctl start idbconsole


Using runstartupconsole.sh

You can start up the infrastructure tier services using the runstartupconsole.sh script located at your $ORACLE_HOME/bin/ on the machine which contains your infrastructure.


$ cd $ORACLE_HOME/bin
$runstartupconsole.sh start


This command will startup

The AS Meta Data Repository Instance

The Listener

The Enterprise Manager Console

Infrastructure Process Such as OID,OC4J_security,SSO etc.


To startup the middle Tier Services you log in to your middle tier OS user and run the the runstartupconsole.sh from the middle tier ORACLE_HOME.


$ cd $ORACLE_HOME/bin
$runstartupconsole.sh start


This Command will start up

The 10g Enterprise Manager

All OPMN managed process for the middle tier like portal

Using Enterprise Manager Console

You can also use the 10g Enterprise Manager console to start up the infrastructure tier and middle tier services, however you must start up the enterprise manager explicitly before you can use it. The emctl command is used to startup the enterprise manager. The location is $ORACLE_HOME/bin


Start the Application Server Control Console:


(UNIX)ORACLE_HOME/bin/emctl start iasconsole

$emctl start iasconsole



Using OPMN

OPMN stands for the Oracle Process Manager and Notification, is a tool with you can manage the OPMN managed Infrastructure and Middle Tier Porcess. The opmnctl executable is located at the $ORACLE_HOME/opmn/bin.

opmnctl start

This command will start up your opmn process

opmnctl startall


This will start up the opmn process and all process managed by opmn


Start components:

(UNIX) ORACLE_HOME/opmn/bin/opmnctl startall
(Windows) ORACLE_HOME\opmn\bin\opmnctl startall


opmnctl startporc ias-component=component

This will start a specific opmn managed process like SSO
You can also start using the sub-porcess of a component using

opmnctl startproc process-type=process

You could also restart the processs using

opmnctl restartproc ias-component=component

opmnctl restartproc process-type=process



However before using OPMNCTL you must have started your Metadata Respositery Database Instance and the Listener manually.

Shutdown of Application Tier Services


Order Of Shutdown


Your Middle tier Services must be shutdown before you shutdown your infrastructure services.


Using runstartupconsole.sh

You can shutdown the infrastructure tier services using the runstartupconsole.sh script located at your $ORACLE_HOME/bin/ on the machine which contains your infrastructure.

$ cd $ORACLE_HOME/bin

$runstartupconsole.sh stop


This command will stop

All infrastructure tier services

The 10g EM console

The meta data repository instance

The listener

For middle Tier services you must run this command for the middle tier ORACLE_HOME.
Using Enterprise Manager Console

You can also use the 10g EM console to shutdown your middle tier and infrastructure services.

After that you must shutdown your EM console manually using the emctl command

emctl stop iasconsole

Stop the Application Server Control Console:

(UNIX)ORACLE_HOME/bin/emctl stop iasconsole
(Windows)ORACLE_HOME\bin\emctl stop iasconsole




You can also shutdown the Infrastructure services using the EM Console of the infrastructure tier after which you must manually shutdown the EM console manually using emctl at the infrastructure tier.


You must also remember to bring down your Meta Data Repository and Listener manually from the infrastructure home after all the services are brought down.


Using OPMN

Using opmnctl you can shutdown your middle tier services and infrastructure services.

opmnctl shutdown

This shutdown the opmn process and along with it all the managed opmn processes

opmnctl stopall

This command stops all opmn managed process for a particular tier.

Stop components:


(UNIX) ORACLE_HOME/opmn/bin/opmnctl stopall

(Windows) ORACLE_HOME\opmn\bin\opmnctl stopall



You can also stop a specify OPMN managed component using

opmnctl stopproc ias-component=component

or

opmnctl stopproc process-type=process

The EM console on the middle tier and the infrastructure tier needs to be brought down manually using emctl stop iasconsole.
Also the Meta Data Repository Instance and Listener need to be brought down manually.

If your OracleAS Infrastructure contains OracleAS Metadata Repository, stop it as
follows:


a. Set the ORACLE_HOME environment variable to the OracleAS Infrastructure
Oracle home.

b. Set the ORACLE_SID environment variable to the OracleAS Metadata
Repository SID (default is orcl).

c. Stop the OracleAS Metadata Repository instance:


ORACLE_HOME/bin/sqlplus /nolog
SQL> connect SYS as SYSDBA
SQL> shutdown

SQL> quit

d. Stop the Net Listener:

ORACLE_HOME/bin/lsnrctl stop
