java.io.IOException: Plugin not found for system component type 'OUD', plugin type 'PROCESS'>

OUD Version: 12.2.1.3.0

Issue: Unable to start OUD instance created through weblogic script startComponent.cmd oud1


Sample command for creating oud instance from wlst: 

oud_createInstance(scriptName='oudsetup',instanceName='oud1',hostname='localhost',ldapPort=1389,rootUserDN='cn=oudadmin',rootUserPasswordFile='D:\password.txt',baseDN='dc=example,dc=com',sampleData=5,adminConnectorPort= 1444)


Error:

Cause: When per host NodeManager is configured, need to copy JAVA_OPTIONS to Oracle_home/wlserver/server/bin/startNodeMananger.sh script from Domain_Home/bin/startNodeMananger.sh ,without these JAVA_OPTIONS system components cannot work.

Solution: 

Follow below steps to configure per host NodeManager:

Ref: Completing the Node Manager Configuration 

https://docs.oracle.com/middleware/12211/wls/WLUPG/upgrade_dom.htm#WLUPG467

1. Create a directory  named "NodeManager" in the location Oracle_Home/oracle_common/common/ as by default will not have this directory.
2. Copy nodemanager.domains and nodemanager.properties files from DOMAIN_HOME/nodemanager directory to the newly created NodeManager directory from item 1.
3. Copy the Security folder from DOMAIN_HOME to ORACLE_HOME/oracle_common/common/NodeManager directory.
4. Edit nodemanager.properties file and change these parameters.

From:

DomainsFile=<PATH to Domain_Home>/nodemanager/nodemanager.domains
NodeManagerHome=<PATH to Domain_Home>/nodemanager
LogFile=<PATH to Domain_Home>/nodemanager/nodemanager.log

To:

DomainsFile=<PATH to ORACLE_HOME>/oracle_common/common/nodemanager/nodemanager.domains
NodeManagerHome=<PATH to ORACLE_HOME>/oracle_common/common/nodemanager
LogFile=<PATH to ORACLE_HOME>/oracle_common/common/nodemanager/nodemanager.log

5. Edit the nodemanager.domains file and add the following lines:

DomainsFile=<PATH to ORACLE_HOME>/oracle_common/common/nodemanager/nodemanager.domains
NodeManagerHome=<PATH to ORACLE_HOME>/oracle_common/common/nodemanager

6. In the same nodemanager.domains file add the the Name and PATH of the domain which needs to be monitored

base_domain=<PATH to DOMAIN_HOME>

7. Keep a backup of startNodeManager.sh/cmd script

8. Copy first JAVA_OPTIONS and POST_CLASSPATH from startNodeManager.sh/cmd script under DOMAIN_HOME/bin to startNodeManager.sh/cmd under ORACLE_HOME/wlserver/server/bin script before the WL_HOME parameter

9. Copy the remaining JAVA_OPTIONS and PATH from startNodeManager.sh/cmd script under DOMAIN_HOME/bin to startNodeManager.sh/cmd under ORACLE_HOME/wlserver/server/bin script after the WL_HOME parameter

10. After the above changes, the first few lines of startNodeManager.sh/cmd under ORACLE_HOME/wlserver/server/bin looks similar to this

SETLOCAL

set JAVA_VM=

set MEM_ARGS=

FOR /f %%i in ('cd') do set MYPWD=%%i

SET SCRIPT_PATH=%~dp0

FOR %%i IN ("%SCRIPT_PATH%") DO SET SCRIPT_PATH=%%~fsi

@rem copied from domainhome\bin 

set JAVA_OPTIONS=%JAVA_OPTIONS% -Doracle.security.jps.config=D:\oracle\12c\Middleware\Oracle_Home\user_projects\domains\oud_domain\config\fmwconfig\jps-config-jse.xml -Dcommon.components.home=D:\oracle\12c\Middleware\Oracle_Home\oracle_common -Dopss.version=12.2.1.3

if NOT "%POST_CLASSPATH%"=="" (

set POST_CLASSPATH=D:\oracle\12c\Middleware\Oracle_Home\oracle_common\modules\oracle.jps\jps-manifest.jar;%POST_CLASSPATH%

) else (

set POST_CLASSPATH=D:\oracle\12c\Middleware\Oracle_Home\oracle_common\modules\oracle.jps\jps-manifest.jar

)

@ rem copied data end here

set WL_HOME=D:\Oracle\12c\Middleware\Oracle_Home\wlserver

set _startnm_params=%*

@rem copied from domainhome\bin 

set DOMAIN_HOME=D:\oracle\12c\Middleware\Oracle_Home\user_projects\domains\oud_domain

for %%i in ("%DOMAIN_HOME%") do set DOMAIN_HOME=%%~fsi

set JAVA_OPTIONS=%JAVA_OPTIONS% -Dweblogic.RootDirectory=%DOMAIN_HOME% 

set JAVA_OPTIONS=-Doud.product.home=D:\oracle\12c\Middleware\Oracle_Home\oud %JAVA_OPTIONS%

@ rem copied data end here

11. Save the file startNodeManager.sh/cmd .

12. Start per host Nodemanager ORACLE_HOME/wlserver/server/bin

13. Start AdminServer using startWeblogic.sh/cmd

14. Now start Oracle OUD instance using  startComponent.cmd oud1
