Known issues, limitations, and workarounds

Problems and limitations are identified with a change request (QCCR) number. For more information about known problems, visit, or contact your Support representative directly.

Title: Upgrade from the version 3.01 to 3.04 (version 3.01 to 3.02 then to 3.03 and finally upgraded to 3.04) fails because of old Vertica client (QCCR8D103500).

Description: The database updates are missing when OBA is upgraded from the older versions such as 3.01, 3.02 to 3.04.

Workaround: If you upgrade from an older version (3.01, 3.02) of OBA to 3.04, then run the following step after extracting the packages and before starting the upgrade:

Install the new vertica client driver on all machines (server and collectors) - rpm -U Analytics_Installation/packages/vertica-client-8.1.1-0.x86_64.rpm.

Title: Anamoly events are not available in OBM UI ( QCCR8D103475).

Description: Anomalies detected in OBA are not available in OBM UI ( Event browser)

Workaround: None.

Title: Anomalies are displayed wrongly if the timestamp of the incoming breaches are not in chronological order (QCCR8D103360).

Description: If the timestamps of the incoming breaches are not in chronological order, anomalies are not displayed correctly.

Workaround: None.

Title: After configuring OBA for SSL - Health overview is not working anymore (QCCR8D99651).

Description: After configuring OBA for SSL, Health overview does not work.

Workaround: None.

Title: Downgrade to 3.03 from 03.04.140 fails (Some processes are not running) (QCCR8D103539).

Description: After downgrading from 03.04.140 to 03.03 some of the opsa processes are not running on server and collector.

Workaround: None.

Title: OBA 3.04 Upgrade: OMi Events dashboard moved from category "Predefined" to "Shared" after upgrade (QCCR8D103385).

Description: After upgrading OBA from 3.03 with consolidated hotfix2 to OBA 3.04 in the E2E Exelon environment, the dashboard "OMi Events" is listed in the "Shared" category instead of "Predefined" category.

Workaround: To resolve this issue, follow these steps:

  1. As a user opsa, run the following commands on the OBA server:
    [opsa@oba bin]$ cd /opt/HP/opsa
    [opsa@oba bin]$ ./ -u opsatenantadmin -p <password> -i -f opt/HP/opsa/inventory/lib/hp/dashboard/default.xml -o
  2. Delete the OMi Events dashboard from OBA 3.03:
    1. In OBA, go to dashboard icon.pngDashboards.
    2. Click oba menu.pngand select Manage.
    3. In Custom Dashboard Manager, select the OMi Events dashboard and click OK.

Title: Log search for terms containing minor separators don't not work (QCCR8D64562).

Description: Searching with special characters does not work. For example, a query for #344 does not match rows like #344:.

Workaround: Only search using numbers and characters, not special characters.

Title: OBA UI requests XQL suggestions (QCCR8D94989).

Description: The OBA UI requests suggestions for XQL even if you are not in the log search UI. This request generates unnecessary load on the Vertica database.

Title: After installation there are no metrics displayed in the "Health Overview" dashboard (QCCR8D96577).

Description: After the installation of OBA 3.03, no metrics are displayed in the "Health Overview" dashboard.

Workaround: Restart the OBA collector after installing OBA 3.03.

Title: After installation there are no indices on column: opsa_default.opsa_collection_message.message (QCCR8D96576).

Description: After the installation of OBA 3.03, the text search does not work.

Workaround: Restart the OBA application server after installing OBA 3.03.

Title: OPSA flume.conf wipes its previous configuration state on adding new collection (QCCR8D94638).

Description: In an environment with multiple OBA application servers, the servers overwrite each other's collector configurations.

Workaround: Configure the collections with only one server.

Title: The events in Splunk are only partly imported into OBA (QCCR8D99344).

Description: The events in Splunk cannot be completely imported into OBA. Each message imported into OBA only contains part of the content.

Workaround: This is due to the default regular expression OBA uses to parse the Splunk data. You can modify the regular expression in the Splunk Source Type Mapping UI so that it fits the data coming in from Splunk.

Title: While upgrading from OBA 3.02 to 3.03, the error occurs due to wrong standalone.xml file ( QCCR8D100531)

Description: The following error appears - Error occurred while configuring SSL: null

Workaround: None
