Solution: Execute the following steps to fix this issue.

• Rename jdk to jdk

  [oracle@oralin2 ~]$ echo $ORACLE_HOME /u01/app/oracle/OracleHomes/agent10g [oracle@oralin2 ~]$ cd $ORACLE_HOME [oracle@oralin2]$ ls -ld jdk* drwxr-xr-x 6 oracle oinstall 4096 Jul 17 09:03 jdk2012-07-17_09-35-41-AM drwxr-x--- 7 oracle oinstall 4096 Jul 16 20:56 jdk2012-07-17_09-03-00-AM [oracle@oralin2]$ mv jdk2012-07-17_09-35-41-AM jdk

• Run root.sh from AGENT_HOME.

  [oracle@oralin2]$ su - Password: [root@oralin2 ~]# /u01/app/oracle/OracleHomes/agent10g/root.sh Finished product-specific root actions.

• Verify the jdk director at AGENT_HOME and size of the file.
