OIM 11g High Availability Deployment

Question

Hi Experts,
I'm deploying OIM 11g in High Available schema, following Oracle docs: http://download.oracle.com/docs/cd/E14571_01/core.1111/e10106/imha.htm#CDEFECJF, I have succesfully installed and configured OIM & SOA in weblogic domain on 'OIMHOST1', trying to propagate the configuration from 'OIMHOST1' to 'OIMHOST2' I have packed (using pack.sh) the domain on 'OIMHOST1' and unpacked (using unpack.sh) it to 'OIMHOST2' so I have updated the NodeManager executing setNMProps.sh and finally Ihave started the NodeManager. In order to Test everything is fine and following the documentation I'm traying to perform the following steps, but I'm not succeed
I'M MUST TO SAY THAT I'M RUNNING ON SINGLE STANDARD EDITION DB INSTANCE AND NOT RAC AS MENTIONED IN ORACLE DOCS, PLEASE CLARIFY IF RAC IS REQUIRED, FOR NOW I'M IN DEVELOPMENT ENVIRONMENT, SO I THINK RAC IS NOT REQUIRED FOR NOW, PLEASE CLARIFY
8.9.3.8.3 Start the WLS_SOA2 and WLS_OIM2 Managed Servers on OIMHOST2
Follow these steps to start the WLS_SOA2 and WLS_OIM2 managed servers on OIMHOST2:
Stop the WebLogic Administration Server on OIMHOST2. Use the WebLogic Administration Console to stop the Administration Server.
Start the WebLogic Administration Server on OIMHOST2 using the startWebLogic.sh script under the $DOMAIN_HOME/bin directory. For example:
/u01/app/oracle/admin/OIM/bin/startWebLogic.sh > /tmp/admin.out 2>1&
Validate that the WebLogic Administration Server started up successfully by bringing up the WebLogic Administration Console.
Here its not possible start AdminServer on OIMHOST2, first of all, it looks like boot.properties file under WLS_OIM_DOMAIN_HOME/servers/AdminSever/security is not valid, the first time I try to execute startWeblogic.sh script, it ask for username/password, I have updated boot.properties (vi boot.properties) and manually set clear username and password, this time startWeblogic.sh script passed this stage, but fails:
<Error> <util.install.help.BuildMasterHelpSet> <BEA-000000> <IOException ioe java.io.IOException: No such file or directory>
<Error> <oracle.adf.share.config.ADFMDSConfig> <BEA-000000> <MDSConfigurationException encountered in parseADFConfigurationMDS-01330: unable to load MDS configuration document
MDS-01329: unable to load element "persistence-config"
MDS-01370: MetadataStore configuration for metadata-store-usage "writeable" is invalid.
MDS-00503: The metadata path "/u01/app/oracle/product/Middleware/user_projects/domains/IDMDomain/sysman/mds" does not contain any valid directories.
I have verified that this directory "mds" does not exists, as reported by the IOException, in OIMHOST2, but it exists in OIMHOST1. from here its not possible for me following Oracle's documentation, I test this starting Adminserver in OIMHOST1, and starting WLS_SOA2 and WLS_OIM2 managed servers from OIMHOST1 AdminServer console, I have tested 2 ways:
1.- All managed servers in OIHOST1 are shutdown, for this, managed servers in OIMHOST2 works as expected
2.- All managed servers in OIMHOST1 are RUNNING, for this, first I have started SOA2 managed server, after that, I have fired OIM2 managed server, when it finish boot process the following message appears in server's output:
<Warning> <org.quartz.impl.jdbcjobstore.JobStoreCMT> <BEA-000000> <This scheduler instance (servername.domainname1304128390936) is still active but was recovered by another instance in the cluster. This may cause inconsistent behavior.>
Start the WLS_SOA2 managed server using the WebLogic Administration Console.
Start the WLS_OIM2 managed server using the WebLogic Administration Console. The WLS_OIM2 managed server must be started after the WLS_SOA2 managed server is started.
8.9.3.9 Validate the Oracle Identity Manager Instance on OIMHOST2
Validate the Oracle Identity Manager Server instance on OIMHOST2 by bringing up the Oracle Identity Manager Console using a web browser.
The URL for the Oracle Identity Manager Console is:
http://oimvhn2.mycompany.com:14000/oim
Log in using the xelsysadm password.
Your help is highly apprecciated

Hi Vaasu,
I have succeeded deploying OIM in HA, just now my customer and I are working on the installation of webtier. Now I have a better understand about HA concepts and the way weblogic works -really nice, but little tricky-
All the magic about HA is configuring properly the network interfaces in each Linux boxes (our case) so, first of all you need to create 2 new floating IP's on each Linux boxes (google: how to create virtual Ip in linux, if you don't know) clone and modify your 'eth0' network script to create the virtual IPs
Follow the procudere in the HA guide: http://download.oracle.com/docs/cd/E14571_01/core.1111/e10106/imha.htm#CDEFECJF
create DB schemas with RCU
install weblogic
install SOA
patch SOA
install IAM
---if you are working on a virtual machine is good idea to take a snapshot here---
Create and configure the weblogic domain (special attentention whe configuring the cluster), see step 13 of 8.9.3.2 Creating and Configuring the WebLogic Domain for OIM and SOA on OIMHOST1, here you need to cofigure:
For the oim_server1 entry, change the entry to the following values:
Name: WLS_OIM1
Listen Address: the IP that is confured in eth0:1 of Linux box1
Listen Port: 14000
For the soa_server1 entry, change the entry to the following values:
Name: WLS_SOA1
Listen Address: the IP configure on eth0:2 of Linux box1
Listen Port: 8001
For the second OIM Server, click Add and supply the following information:
Name: WLS_OIM2
Listen Address: the IP configured on eth0:1 of Linux box2
Listen Port: 14000
For the second SOA Server, click Add and supply the following information:
Name: WLS_SOA2
Listen Address: the IP configured on eth0:2 of Linux box2
Listen Port: 8001
Click Next.
On Step 16 ensure you are using the UNIX tab to configure the machines, also ensure that for machine1 you use the IP configured on the eth0 interface of Linux box1, the same for machine2
please confirm you have performered 8.9.3.3.2 Update Node Manager on OIMHOST1
if everything is ok you must be able to start the AdminServer as described in the guide.
configure OIM: 8.9.3.4.2 Running the Oracle Identity Management Configuration Wizard, in my case I don't need LDAPsync, I have skipped this section, if you configure properly OIM, then you mus perform 8.9.3.5 Post-Configuration Steps for the Managed Servers
resrtar AdminServer then from the weblogic console, start OIM and SOA if node manager is properly configured SOA and OIM must run properly, update deployment mode and coherence as described in the guide and verify that OIM run perfectly in Linux box1.
Propagate OIM from Linux box1 to Linux box2 as described in the guide, using pack and unpack (you MUST use the same filesystem directory structure on both Linux boxes)
Update and start NodeManager as described in the guide
VERY IMPORTAN OBSERVATION
the guide say:
8.9.3.8.3 Start the WLS_SOA2 and WLS_OIM2 Managed Servers on OIMHOST2
Follow these steps to start the WLS_SOA2 and WLS_OIM2 managed servers on OIMHOST2:
Stop the WebLogic Administration Server on OIMHOST2. Use the WebLogic Administration Console to stop the Administration Server.
JUAN OBSERVATION:
IS NOT POSSIBLE TO START OR STOP ADMINSERVER ON HOST2 SINCE ADMIN SERVER WERE CONFIGURED TO LISTEN ON THE IP ADDRES OF eth0 INTERFACE ON HOST1, SO, ITS NOT POSSIBLE TO PLAY IT ON HOST2, I THINK AND ADDITIONAL PROCEDURE SHOULD BE FOLLOWED TO CONFIGURE ADMINSERVER IN HA IN A ACTIVE-PASSIVE MODE
Start the WebLogic Administration Server on OIMHOST2 using the startWebLogic.sh script under the $DOMAIN_HOME/bin directory. For example:
/u01/app/oracle/admin/OIM/bin/startWebLogic.sh > /tmp/admin.out 2>1& -----NOT APPLICABLE
Validate that the WebLogic Administration Server started up successfully by bringing up the WebLogic Administration Console. -----NOT APPLICABLE
Start the WLS_SOA2 managed server using the WebLogic Administration Console. ----START SOA2 FROM THE CONSOLE RUNNING ON HOST1, IT DOESN'T MATTER
Start the WLS_OIM2 managed server using the WebLogic Administration Console. The WLS_OIM2 managed server must be started after the WLS_SOA2 managed server is started. ------ START OIM2 FROM THE CONSOLE RUNNING ON HOST1
HERE YOU MUST BE ABLE TO LOGIN TO OIM2 SERVER AS DESCRIBED IN THE GUIDE, YOU DON'T NEED TO EXECUTE config.sh SCRIPT THIS SHOULD WORK AS DESCRIBED.
Server migration should work straight-forward if you have configured the floating IPs as described, I have not configured the persistence yet since my customer does not have the skills to share a storage.
I hope this helps, and feel free to comment or complement.
By the way, did you know how to set up a valid SSL certificate in Windows 2003 server??? I need it to test and Exchange 2007 I'm tryin to integrate
