Configure multiple Java Method Server (JMS) JBoss for multiple Documentum Content Server 6.5 SP1

Hi all.

We have a Docbase in Documentum 6.5 SP1 with many concurrent users and transactions. So we want to balance the workload, we have two Content Server now directed to a docbase, but the second Content Server is assigned the Java Method Server (JMS) from the original installation. We want each Content Server has its own Java Method Server (JMS).

How do I setup a second Java Method Server (JMS) and assign it to my Content Server?

In the link:

https://community.emc.com/message/67220
It refers to the link:
https://forums.emc.com/forums/thread.jspa?threadID=134905
where should be the instructions, but the link does not display the page.

We want to have the following architecture:

___ Content Server 1 __ ---> __Java Method Server 1 __

Docbase --- <

\___ Content Server 2 __ ---> __Java Method Server 2 __

How did you create multiple content server? I believe you did that using - Configuring Multiple Content Servers on a Single Host for a Particular Repository - Chapter -11 of content server installation guide. If yes you wont have 2 JMS.

For Jboss -

1 . copy the root directory of your jboss with all its files/folders. so under $DOCUMENTUM/shared/ you have now 2 directories for jboss. i.e.
$DOCUMENTUM/shared/jboss4.2.0/
$DOCUMENTUM/shared/jboss4.2.0_2/

2. Delete all files/folders under 'tmp'/'work' and 'log' directory of JBoss_2, which is in the following location:
$DOCUMENTUM/shared/jboss4.2.0_2/server/DctmServer_MethodServer/work/
$DOCUMENTUM/shared/jboss4.2.0_2/server/DctmServer_MethodServer/tmp/
$DOCUMENTUM/shared/jboss4.2.0_2/server/DctmServer_MethodServer/log/

3. Each instance of JBoss runs on its own port, and it uses 2 ports for its internal use. i.e 9080/9090. Navigate to the home directory of JBoss_2, and search/replace these 2 ports for the ports that you want to use for your second instance of JBoss_2. i.e. 9180/9190, in all xml/properties config files.

4. Again navigate to jboss_2 home directory and search for each occurance of JBoss path with the correct one (i.e. jboss4.2.0_2) in each xml/properties config files (exclude jars).

5. In your second docbase, login to iapi and retrieve your dm_server_config object. i.e.

API>retrieve,c,dm_server_config
...
<r_object_id>
API>set,c,l,app_server_uri[0]
SET>http://localhost:9180/DmMethods/servlet/DoMethod
...
OK
API>set,c,l,app_server_uri[1]
SET>http://localhost:9180/DmMail/servlet/DoMail
...
OK
API>save,c,l
...
OK
API>

Note: that 9180 is just an example of a port which I use. You need to make sure that you choose a port which is available. Hint: verify /etc/services file to see if the port that you intend to use is available.

6. Re-start docbase/JMS.

You should be good to go.

You can follow the same steps for your next docbase(s).

Hint: For step 3 and 4, you can use the following unix command to findout where the occurance of port/path for jboss is:

- Navigate to the JBoss_2 home directory:
cd $DOCUMENTUM/shared/jboss4.2.0_2/

To find JMS port references:
find . -exec grep '908' {} \; -print >ports.txt

To find JMS path references:
find . -exec grep 'jboss' {} \; -print >path.txt

The above commands will output the result in ports.txt and path.txt. Discard any entries for jars.

Follow this note to configuer additional java method Server -

https://solutions.emc.com/emcsolutionview.asp?id=esg98906

How to configure additional D6 BEA Weblogic Java method Servers?

Symptoms

Degraded performance of BEA Weblogic Java Method Server in installations with multiple Docbases or frequent usage of custom java methods.

Cause

Installations with multiple Docbases or frequent usage of custom java methods.

Resolution

Run multiple instances of the Java Method Server. Instances may be assigned to individual Docbases or App Servers defined in serverconfig to distribute load.

Assumptions

Content Server installed into default locations
Installation Owner is dmadmin
The new Java Method Server is created in the existing BEA Weblogic Domain
The name of the new Method Server is "DctmServer_MethodServer_Two"
The port for the new Method Server is 9081.

Procedure

Where <CSHost> is the Content Server Host Name. The username is "weblogic" and the password is the password entered during Content Server Installation.

Create a new server:
- Select Servers from Domain Configurations - Environment. All servers are listed on the Summary of Servers page.
- Select the Lock & Edit button
- Select (check) the server named DctmServer_MethodServer_<CSHost>
- Select the Clone button: The Clone a Server page is displayed.
- Enter the Server Name, "DctmServer_MethodServer_Two"
- Enter the Server Listen Port, 9081
- Select Ok to save. The new server is listed on the Summary of Servers page.
- Select the Activate Changes button to save. The message "All changes have been activated. No restarts are necessary." is displayed at the top of the Summary of Servers page.
Return to the console home page and select Deployments from Domain Configurations - Your Deployed Resources. A list of applications is displayed on the Summary of Deployments page.
For each application, acs, bpm, dfs, ServerApps, â€¦ to deploy:
- Select the application to deploy to the new server. The application Settings page is displayed
- Select the Targets tab. The applications current server targets are shown as a comma separated list. The list does not contain the name of the new server.
- Select the Lock & Edit button
- Select (check) the listed component (application)
- Select the Change Targets button. A list of all available servers is displayed. The new server is not selected (checked).
- Select (check) the new server
- Select the Yes button to save
- Select the Activate Changes button to save. The applications current server targets are shown as a comma separated list. The list now contains the name of the new server.
Verify deployments for the new server
- Return to the Summary of Servers page
- Select the new server to display the server's settings page.
- Select the Deployments tab.
- All applications are listed.
Log in to the Content Server host as the installation owner (dmadmin)
Create startup and shutdown scripts for new server
- Navigate to ...\bea9.2\domains\DctmDomain which is located in the Documentum User Directory.
- Copy startMethodServer.cmd to startMethodServerTwo.cmd
- Edit startMethodServerTwo.cmd. Change all occurrences of the server name "DctmServer_MethodServer_<CSHost>" to the name of the new server, "DctmServer_MethodServer_Two"
- Copy stopMethodServer.cmd to stopMethodServerTwo.cmd
- Edit stopMethodServerTwo.cmd. Change all occurrences of the server name "DctmServer_MethodServer_<CSHost>" to then name of the new server, "DctmServer_MethodServer_Two"
Edit the Windows Documentum Java Method Server service to add a component for the new server:
- Navigate to â€¦\DctmDomain\ServiceConfig\MethodServer\Conf
- Edit DmMethodServer.xml.
- - Copy and paste the <component name="Managed Server"> section to create a new server component.
  - Change the <component> name to "Managed Server Two".
  - Change the <start> command to startMethodServerTwo.cmd
  - Change the <status> section to command to use the name of the new server, "DctmServer_MethodServer_Two"
  - Change the <stop> command to stopMethodServerTwo.cmd
  - Change the <heartbeat> url port number to 9081
  - Save the file
Stop the Documentum Java Method Server. This could take several minutes
Start the Documentum Java Method Server. This could take several minutes
Examine log file, DmMethodServerService.log , located in â€¦\DctmDomain\ServiceConfig\MethodServer to verify startup.
Verify status of new server and state of deployed applications
- Return to the Summary of Servers page
- Verify that the new server is in the Running state
- Select the new server to display the server's settings page.
- Select the Deployments tab.
- Verify that the applications are in the Active state
Test new server by entering the following URLs in a browser.
- http://<CSHost>:9081/DoMethod/servlet/DoMethod
- http://<CSHost>:9081/ACS/servlet/ACS
- http://<CSHost>:9081/DoMethod/servlet/DoMethod
Edit the Docbase Server Configuration or ACS configuration to use the newly configured server.

Rijo Mathew thanks for reply but after some tests the procedure for D6 BEA Weblogic do not give help for JBoss JAva Method Server.

Raghu

Hello,

I am not sure how you installed the second content server but during the installation of content server software on the second machine it should automatically create a new JMS server. So any processes running on the seconf CS should use the JMS on the second server.

I might not have understood your requirement properly so if it's not clear please post more details so that we can help you

Regards

Raghu

lastnitescurry

agree with Raghu, The 2nd Content Server install should have configured a local JMS. In your repository you should see 2 servers listed. In the properties of each server, there is "App Servers" tab which has the URL link to the JMS. By default that is to localhost.

Check your docbroker projectection settings if all requests (include methods) are going to one server.

For Jboss -

4. Again navigate to jboss_2 home directory and search for each occurance of JBoss path with the correct one (i.e. jboss4.2.0_2) in each xml/properties config files (exclude jars).

5. In your second docbase, login to iapi and retrieve your dm_server_config object. i.e.

6. Re-start docbase/JMS.

You should be good to go.

You can follow the same steps for your next docbase(s).

Hint: For step 3 and 4, you can use the following unix command to findout where the occurance of port/path for jboss is:

- Navigate to the JBoss_2 home directory:
cd $DOCUMENTUM/shared/jboss4.2.0_2/

To find JMS port references:
find . -exec grep '908' {} \; -print >ports.txt

To find JMS path references:
find . -exec grep 'jboss' {} \; -print >path.txt

The above commands will output the result in ports.txt and path.txt. Discard any entries for jars.

Hello

I followed the instructions on the note of support.

"Hosting Multiple JMS"
https://community.emc.com/message/65527

And I install a new JMS in my development environment. I have a Windows Server 2003 environment so I use the NetBeans IDE to find all ports and all the paths I had to change. Would be helpful to have a guide which lists the ports and paths that should be altered.

At this moment I have a JMS more in my development environment is working well, if it continues to work normally in a few days I will add another JMS to my production environment.

Thank you very much for the help.
