[Solved] Application launch error in Oracle EBS R12.1

In this post, we are going to cover the issue and its fix that one of our trainees was facing this issue while accessing Oracle EBS R12.1.3 application. They were getting this error java.lang.NoClassDefFoundError: Could not initialize class oracle.apps.fnd.profiles.Profiles.

The following error occurred after patching EBS to 12.1.3 don’t worry we have got you covered in this blog.

Let’s check in the error log why this happened, go to $IAS_ORACLE_HOME/j2ee/oacore/logs and check the log file

Error:

Request URI:/OA_HTML/AppsLocalLogin.jsp

Exception:

Solution:

There are two ways in which the issue can be resolved now.

1. We can resolve this issue by Bouncing the database on each node in case of RAC.

OR

2. You can make below changes in application and bounce services:

1. Backup the Jserv.properties file. (Backing up the original file is the best practice, if anything goes sideways you can restore the original state of the system.)

2. changing the value of the LONG_RUNNING_JVM=  parameter from “true” to “false” in Jserv.properties file.

grep -i wrapper.bin.parameters=-DLONG_RUNNING_JVM Jserv.properties
wrapper.bin.parameters=-DLONG_RUNNING_JVM=false

3. Stoping adapactl.sh stop (To ensure that all the serves are stoped)

cd $COMMON_TOP/admin/scripts/$CONTEXT_NAME
adapactl.sh stop

4. Clearing server-level cache:

cd $COMMON_TOP
mv _pages _pages_09July2014
mkdir _pages

5. Clearing modplsql caches:

cd  $IAS_ORACLE_HOME/Apache/modplsql/
mv cache cache_09July2014
cd cache
rm -rf *

6. Clearing Apache logs

cd $IAS_ORACLE_HOME/Apache/Apache/
mv logs logs_09July2014
cd logs
rm - rf *

 Start Services:

Now try starting the services

cd $COMMON_TOP/admin/scripts/$CONTEXT_NAME
adapactl.sh start.
