When you change the Java Runtime Environment (JRE) for HCL
VersionVault, you must reconfigure the product to make
it work with the new JRE.
About this task
After your initial installations of Java and the Java Runtime Environment (JRE) and
VersionVault, there might be times that you want to
change your JRE. For example, you might want to switch to a newer JRE if there is a security issue
for the older one.
Procedure
To reconfigure VersionVault to use a
different JRE:
-
Install the new Java and its JRE.
Note: If in your initial installation of a JRE you installed it in a folder with a
folder name that does not identify the version number of the Java (as an example, "jdk" and not
"jdk_v8.0"), then you can install the updated Java into the same file system location as the initial
Java. If you did not do so at that time, then consider doing that now. No reconfiguration of
VersionVault is necessary when your JRE installation
is updated into the previous installation folder.
-
Use any one of the following methods to reconfigure VersionVault to use the new JRE:
- If you initially installed your JRE with a folder name that did not specify what version of
Java, install the updated Java into the same file system location as the initial Java. Then no
reconfiguration of VersionVault is needed. If this
method is not applicable, see the next methods.
- Uninstall VersionVault and then reinstall
it. During the reinstallation, specify a different JRE path.
- Or, edit the VersionVault JRE configuration:
- On Linux/UNIX: As super-user, edit the script in /opt/hcl/ccm/common/java/jre/javawrapper.sh and set the
JRE_ROOT value to the directory containing the java executable.
For example, if the java
executable is installed in /opt/jre-newversion/bin/java, specify
JRE_ROOT="/opt/jre-newversion/bin"
- On Windows: As administrator, edit the Windows registry value.
- HKEY_LOCAL_MACHINE\Software\HCL\CCM\JavaRuntimeDir
The string value is the path to the directory containing the java executable.
For
example, if the java executable is installed in C:\Program
Files\jdk8u212-b03\jre\bin\java.exe, specify C:\Program
Files\jdk8u212-b03\jre\bin
