Resolution
Foglight Upgrade Guide | Update the Java Runtime Environment
Both the FMS and the FglAM require a JRE. Each release is shipped with a specific versions of the JRE, that is bundled with the product. Quest Software Inc. audits security bulletins from Sun related to the JREs, which has been shipped and if any are determined to be applicable to the Foglight code, a security update incorporating the fixes will be released.
It is not recommend to use a different JRE version, as it is difficult to confirm that it will perform correctly. However, within particularly stringent security requirements it may be required to do so. If the JRE must be upgraded, Quest will make good faith efforts to support the activity according to the following guidelines:
- The JRE must be on the same major release branch and must only update the 4th set of digits in the version number (i.e. 1.6.0.xx")
- Problem replication:
- Advise support that FMS/FglAM is operating with a non-standard JRE
- Quest will first try to reproduce errors on our "shipped version" JRE
- Quest will try to reproduce problems on the "upgraded version" JRE
- If Quest cannot replicate the problem on either, it is possible the recommendation will be to return to the "shipped version" JRE
- Use the upgrade processes noted below::
- For Foglight Agent Manager:
- Stop Foglight Agent Manager
- In the "jre" subdirectory of the Foglight Agent Manager installation directory, create a new directory with the version number of the new JRE to be installed (with all components separated by '.', i.e. 1.6.0.29)
- Unpack the new JRE into that directory
- Restart Foglight Agent Manager, which will look for and use the newest JRE available to it.
- For Foglight Management Server
- Stop the Foglight Management Server
- Rename $FMS_HOME/jre to $FMS_HOME/jre.bak
- Create a new directory $FMS_HOME/jre
- Unpack the new JRE into the new directory $FMS_HOME/jre
- Restart the Foglight Management Server
- For Foglight Agent Manager:
Additional Information:
1) Access Java web site for Latest JRE:
2) Download both 32 bit & 64 bit Solaris (required): This example was for the earlier 1.6.0_29 release.
Solaris (32-bit) file size: 24.3 MB
Solaris (64-bit) file size: 10.3 MB3) Chmod 755 both jre-6u29-solaris-sparcv9 & jre-6u29-solaris-sparc .sh files.4) Execute both in a directory outside of $FGL_HOME.5) Save $FGL_HOME/jre directory to .bak extension & move new _29 update to $FGL_HOME/jre
mv $FGL_HOME/jre $FGL_HOME/jre.bak
mv jre1.6.0_29 $FGL_HOME/jre6) Start FMS
The FMS log will indicate the new JRE version as shown:Foglight Server(build ) on solaris sparc64 5.10, Java 1.6.0_29 (64 bit).
For JRE updates on Windows 32-bit / 64-bit machines:1) Access Java web site for Latest JRE.
2) Download the specific version for the system:
Windows 7, XP Offline: 16 MB
Please note that the Java web site detects the browser version in use. If the browser is 32-bit, it will be offered to download the JRE 32-bit update. For 64-bit systems, please use a 64-bit browser.
3) Stop FMS.
4) Go to $FGL_HOME and rename the jre directory to jre.bak.5) Create a new directory called jre.
6) Go to the command line and type the following command:
C:\>
\ INSTALLDIR=D:\Quest_Software\Foglight\jre As an example: C:\> c:\jre-6u29-windows-x64.exe INSTALLDIR=D:\Quest_Software\Foglight\jre
7) Start FMS.
