The following sections outline the key features and functions provided by this version, as well as issues resolved in this release:
Sentinel 188.8.131.52 upgrades the Java Runtime Environment from version 184.108.40.206 to version 1.7.0_17 because Oracle no longer supports version 1.6.
With Sentinel 220.127.116.11 and later, Sentinel replaces the Event Source Overview Sync Report Data Definition (RDD) with Source Summary RDD. The Source Summary RDD stores only relevant events and therefore improves the reports performance.
Sentinel 18.104.22.168 includes Sentinel Core Solution Pack 2011.1r4, which automatically replaces the RDD for reports created using the Event Source Overview Sync RDD with the Source Summary RDD. If you have custom reports that use the Event Source Overview Sync RDD, you need to update those reports to use the Source Summary RDD.
Sentinel 22.214.171.124 upgrades the following Actions, Integrators, and Solution Pack plug-ins. These versions include the latest software fixes, documentation updates, and enhancements for the plug‐in. For more information, refer to the specific plug-in documentation.
Event Forwarder 2011.1r1
Execute a Command 2011.1r1
Send E-mail 2011.1r2
Sentinel Link 2011.1r2
Send SMS 2011.1r1
File Integrator 6.1r3
Sentinel Link Integrator 2011.1r2
Sentinel Core Solution Pack 2011.1r4
Sentinel 126.96.36.199 provides software fixes for the following issues. For the list of software fixes and enhancements in previous releases, see the Sentinel 188.8.131.52 Documentation Web site.
Issue: Sentinel runs out of memory when the actions trigger rate is more than the action execution rate. This issue occurs because there is no limit for the number of actions to queue up, which eventually causes actions to consume all of the system memory. (BUG 807834)
Fix: Sentinel now sets a limit for the number of actions that can be in queue. Sentinel also allows you to configure the number of threads that should simultaneously process actions. This number specifies the action execution rate. You can change the default values as necessary. The higher the value, the more memory is consumed.
To change the default values:
Log in to the system as the root user.
Open the /etc/opt/novell/sentinel/config/configuration.properties file.
Edit the sentinel.actions.executor.queue.size property to specify the desired value. This value specifies the number of actions allowed to be in the queue. The default value is 10000.
Edit the sentinel.actions.executor.thread.size to specify the desired value. This value specifies the number of threads that should process the actions. The default value is 4.
Restart the Sentinel server.
Issue: If the Sentinel server is restarted when the disk space is full or when there are too many open files, Sentinel might delete or overwrite the host.id and sentinel.id files. Deletion or modifications to these files alters the unique IDs contained in these files. (BUG 810854)
Fix: Sentinel now handles out of disk space and open files issues, and does not delete or overwrite these system files.
Issue: Sentinel generates an audit event flagged as Success even when the Execute Command action associated to a correlation rule fails to execute. (BUG 812522)
Fix: Sentinel now flags the audit event as Failed when the Execute Command actions fails to execute.
Issue: When you edit the schedule of a scheduled report, Sentinel logs the NullPointerException in the server log even though Sentinel edits the report schedule. (BUG 808990)
Fix: Sentinel no longer logs the exception when you edit a scheduled report.
You can upgrade to Sentinel 184.108.40.206 from Sentinel 7.0 or later.
For information on hardware requirements, supported operating systems, and browsers, see NetIQ Sentinel 7.0.1 Installation and Configuration Guide.
Download the hotfix from the Novell Patch Finder Web site. For information on upgrading to Sentinel 220.127.116.11, see “Upgrading Sentinel” in the NetIQ Sentinel 7.0.1 Installation and Configuration Guide.
If you upgrade Sentinel from 7.0 to 18.104.22.168, perform the following post-upgrade procedure:
If you installed Sentinel in a non-default location, you must run the following commands as the novell user:
where $RPM_INSTALLATION_PREFIX is the location of the Sentinel installation.
If you are upgrading the appliance from Sentinel 7.0.1 or earlier, the upgrade fails in WebYaST because the vendor name for the patch has changed from Novell to NetIQ. You need to upgrade the appliance by using the zypper patch.
To upgrade the appliance by using the zypper patch:
Log in to the appliance console as the root user.
Run the following command:
Enter 1 to accept the vendor change from Novell to NetIQ.
Enter Y to proceed.
Enter yes to accept the license agreement.
Restart the Sentinel appliance.
