ZDLRA. Configuring Protected Database. Backup Module

Q: In order to install backup module using ra_install.jar i need the java on the server. But there is no java installed on my database server. Should I install the OS java OR it is possible to use any other java ? For example, java from ORACLE_HOME, from GRID home or from opatch directory ?




A: If there is no OS java I use any other java to run ra_install_jar and have no problem :)


Look:

I tested different javas: from Grid home, from OEM agent, from Oracle Home 12.2 and java from OPatch directory - all these javas work well !


The version of the java must be 1.7+, not 1.5, not 1.6.

[root@ed04dbadm01 ~]# /u01/app/agentHome/agent_13.2.0.0.0/oracle_common/jdk/jre/bin/java -version

Or you can use the OS java:
$ which java
/usr/bin/java
