Get the routing id for the OPMN

In order to get the routing ID that is used within OPMN issue the following command:

opmnctl status -app -l

Applications in Instance: as1013

application type: OC4J
pid | name | state | rtid | routable | appctx | parent
3184 | system | started | g_rt_id | true | |
3184 | default | started | g_rt_id | true |/.rmiTunnel| system
3184 | DaonEngine | started | g_rt_id | true | | default
3184 | ascontrol | stopped | g_rt_id | true | |
2852 | system | started | g_rt_id | true | |
2852 | default | started | g_rt_id | true | /.rmiTunnel | system
2852 | bc4j | started | g_rt_id | true | |
2852 | ascontrol | started | g_rt_id | true | | system

The rtid is the routing id. In the above example the routing id is the same for the complete environment.

WebCenter Wiki with 3rd party LDAP

Using a WebCenter Wiki with a 3rd party LDAP is possible but you have to make sure that the following two groups are present and populated in the LDAP:

  • users
  • oc4j-administrators
Also the group search definition must be on Nested.

The next picture shows the basic values for the 3rd party LDAP:

OPMN log and debug configuration

Another gem I found when dealing with a problem. The following piece of code shows the configuration to modify the opmn debug level:

< xmlns="">

< path="$ORACLE_HOME\opmn\logs\opmn.log" comp="internal;ons;pm" size="1500000">

< path="$ORACLE_HOME\opmn\logs\opmn.dbg" comp="internal;ons;pm" size="1500000">


< /opmn >

Now I need to find out which components exist besides internal, ons and pm.

I had run the chgiphost.bat on a Windows AS The reason for this was the fact that the Windows machine was created from a Ghost image.
But after the script has been run successfully I saw that the hostname was still the same in the Application Server Control.

So I created a SR with Support. And today I received a very good answer. Normally Support gives you a statement that it does not work and that's that. But see for yourself what this friendly analyst did say:

The dcmctl setInstanceName is available from 9.0.4 onwards. This will change the instance name in the DCM Repository.
After this you may have to change the targets.xml file with the new instance name. Please note that the above command is not supported as this is not documented."

Ok, very good!
I will make sure that this guy gets an excellent review.

However there is now cmctl in and also no targets.xml :-(

But actually the idea was clear to me.

I went to have a look at the opmn.xml file.

When I changed
< id="as1013.OLDHOSTNAME.mymachine.local" name="as1013.OLDHOSTNAME.mymachine.local">


< id="as1013.NEWHOSTNAME.mymachine.local" name="as1013.NEWHOSTNAME.mymachine.local">

everything worked as I expected it to do.

Scripts for RAC backup

Just want to store them here for myself, but if others use them - well feel free (and drop me a note).

The script for the Cluster Registry


# Author: Andreas Chatziantoniou, Accenture Technology Solutions
# Date : 25-JUN-2007
# Purpose:
# Create a backup of the Oracle Cluster Registry regularly
# Usage:
# ./
# This script should be used from the cron in regular intervals
# Results:
# The backupfile of the Oracle Cluster Registry will be created in the /tmp
# directory. The filename will contain the hostname and the time that
# the backup was created.

OCRBCK=/tmp/ocrbackup.`hostname`.`date +"%Y%m%d%H%M"`
/opt/oracle/crs/bin/ocrconfig -export $OCRBCK

And here is the script for the Voting Disk

# Author: Andreas Chatziantoniou, Accenture Technology Solutions
# Date : 25-JUN-2007
# Purpose:
# Create a backup of the Oracle Voting Disk regularly
# Usage:
# ./
# This script should be used from the cron in regular intervals
# Results:
# The backupfile of the Oracle Voting Disk will be created in the /tmp
# directory. The filename will contain the hostname and the time that the
# backup was created.
# If you have more than one voting disk make sure that each is copied.

OVDBCK=/tmp/ovdbackup.`hostname`.`date +"%Y%m%d%H%M"`
dd if=/dev/rhdiskpower2 of=$OVDBCK

CRS information was lost

Due to a crash a part of the CRS information was lost. Until now I have not found out how this could happen in the first place.
The effects were strange. The instances would not start and there was no indication of an error in the alert_log.

Doing some research in the CRS revealed that the ora.ORCL.db was gone while the ora.ORACL.oracl1.inst was still there.

Creating a new file in the CRS profiles and using crs_register did do the trick.

Such a file should look like this:

Adding users to the system-jazn-data.xml

In another posting I described how to edit the system-jazn-data.xml in order to create a user.

To my astonishment there seems to be a possibility to create these users using the Application Server Control.

Here are the steps:

In the ASC cluster topology click on the OC4J that contains the javasso.

Click on Applications

Select javasso

Click on the module javasso-web

Click on Security provider

Select Realms

In the realm click on the number in the users column.

In this screen you can create users!

Adding the license for the Oracle Webcenter Discussions

It is obvious again that new products that Oracle offers are not always that integrated.

Take for example the Oracle Webcenter Discussions. Although it is from Jives it seems to be fully licensed with the Webcenter.

However the license needs to be provided before the setup can be completed.

Luckily the license is stored in the file jive.license - so just copy and paste it into the webpage.

Add a user to the JavaSSO

In AS 10.1.3.x Oracle came up with the JavaSSO. Seems to be (from a high level perspective) a poor man's version of the SSO from the AS 10.1.2.x.

Having said this it strikes me how little documentation is available for this feature.

But we're explorers, aren't we?

JavaSSO is based on a file based security provider. The two main files are:
- jazn.xml
- system-jazn-data.xml

Both exist in the $OH/j2ee/ directory. This means that if you have more than one OC4J instance you need to edit both.

The most basic task is to add a user. You can - of course try to do this by editing the xml files, but luckily Oracle provides the jazn.jar tool.

Make sure that you use the correct java executable and start it:

java -jar jazn.jar -adduser andreas welcome1

You will be asked for the AbstractLoginModule username (oc4jadmin) and its password.

Now we have a user but usually this has to be added to a role before it can do something useful:

java -jar jazn.jar -grantrole users andreas

Now the user is added and we will prevent the ugly errors - such as:

Application Server Control just gets better

Deployment of an ear file with the Application Server Control usually required to have the ear file on your local host.
Very often this is not the case as your Application Server machine will be humming in the Data Center while you sit comfortable behind your PC or laptop.

But I just found out that the ASC offers a new functionality: specify the location on the host where the ASC is running.

The following screen shot shows this - while I was deploying the Wiki of the Oracle WebCenter:

It even gets better - during the deployment instead of the small clock the messages are displayed:
