These requirements are listed in the Installation and Configuration Guide for HP Operations Manager Dependency Mapping Automation. Before installing HP Operations Manager Dependency Mapping Automation, make sure that your system meets these minimum requirements.

Known Problems, Limitations, and Workarounds

Installation

Configuration and Connection Links Fails to Respond After Install QXCR1000470294

After HP Operations Manager Dependency Mapping Automation has been installed on either HP-UX or Sun Solaris, the Configuration and Connection pages do not respond when attempting to open from the navigation pane on the left. The right content pane remains unchanged. The browser does not indicate that the page is being loaded.

The error appears just once after installation. Once one of the following workarounds has been performed, it does not occur again.

There are two possible solutions:

Preferred Solution

To ensure that the Connection page loads correctly:

1. Open the HPOM DMA UI and click either the Connection or Configuration link in the left navigation pane.

2. Stop and start the trace server daemon using the command appropriate for your operating system:

   • HP-UX
     
     /sbin/init.d/OVTrcSrv stop
/sbin/init.d/OVTrcSrv start

   • Solaris
     
     /etc/init.d/OVTrcSrv stop
/etc/init.d/OVTrcSrv start

   The web UI responds with an error page.

3. Click the Connection or Configuration link again.

The Connection and Configuration page loading should now be successful.

Alternative Solution

To ensure that the Connection page loads correctly:

1. Open the HPOM DMA UI and click either the Connection or Configuration link in the left navigation pane.
2. Stop the ovtomcatB process and restart all ovc process using the following commands:
   
   /opt/OV/bin/ovc -stop ovtomcatB
/opt/OV/bin/ovc -start

3. Login to the HPOM DMA Web UI.
4. Click the Connection or Configuration link again.

The Connection page loading should now be successful.

Synchronization

NullPointerException While Updating HPOM Views QXCR1000449000

It is not possible to synchronize if the CMDB returns 0 objects. This causes a NullPointerException and is visible in the synchronization log file after the log entry stating:

0 Service or Nodes will be synchronized. No synchronization call to OM will be done - so, no update on the node bank and/or service hierarchy will be done.

Solution

It is not possibile to synchronization with 0 CMDB objects. You must ensure that any TQL query you specify is able to return at least one item.

No Message for HPOM Nodes Moved to CMDB_Removed Node Group QXCR1000745658

If nodes already synchronized and added to the CMDB node group are not part of a subsequent synchronization, they are moved to the CMDB_Removed node group. It is expected that such a move is accompanied with a message being displayed in the message browser but these messages are not sent.

When nodes are moved to the CMDB_Removed node group, the following entries are written to the /var/opt/OV/shared/server/log/om/ciws.0.en log file:

WARNING;no jopcagtbase in java.library.path

Solution

To make sure that an associated message is sent to the Message Browser when nodes are removed from the CMDB node group, complete the following steps:

1. Open the following file for editing:
   
   

   /var/opt/OV/conf/tomcat/b/hpenv.sh

2. Change the line:
   
   

   SHLIB_PATH=${SHLIB_PATH}:/opt/OV/lbin/Cadm

   to:

   SHLIB_PATH=${SHLIB_PATH}:/opt/OV/lbin/Cadm:/opt/OV/lib

3. Restart the Tomcat server using the commands:
   
   

   ovc -stop ovtomcatB
ovc -start ovtomcatB

Uninstallation

Removing Service Group Instances in the UCMDB also Removes All Host Instances QXCR1000744037

The hpdma.zip package for the UCMDB and BAC introduces the Service Group CI type. On deployment, Unix, Database and Windows CIs are enriched with a container link relationship from such Service Group CIs.

Before the hpdma.zip package can be undeployed, you must delete all CIs of type Service Group, but because of the container link, the Unix, Database and Windows CIs are also recursively deleted.

To prevent this behavior, you must:

• Switch off the recursive deletion of CIs
• Delete the Service Group CIs
• Switch on the recursive deletion

Solution

1. Switch Off Recursive Deletion

   To switch off the recursive deletion behavior of the container link, complete the following steps:

   1. Open the CI Type Manager:
      
      

      • UCMDB:

        Admin → Modeling → CI Type Manager

      • BAC:

        Admin → Universal CMDB → Modeling → CI Type Manager

   2. Change to the relationships tree on the left pane.
   3. Right-click Container Link and select Edit CIT.
   4. From the Edit Relationship - Container Link window, select the Qualifiers tab.
   5. Delete the RECURSIVE_DELETE entry in the Configuration Item Type Qualifiers list on the right.
2. Delete all CIs of type Service Group.
3. Switch On Recursive Deletion

   To switch on the recursive deletion behavior of the container link, complete the following steps:

   1. Open the CI Type Manager:
      
      

      • UCMDB:

        Admin → Modeling → CI Type Manager

      • BAC:

        Admin → Universal CMDB → Modeling → CI Type Manager

   2. Change to the relationships tree on the left pane.
   3. Right-click Container Link and select Edit CIT.
   4. From the Edit Relationship - Container Link window, select the Qualifiers tab.
   5. Add a qualifier with name RECURSIVE_DELETE to the Configuration Item Type Qualifiers list on the right.

Integration with Other HP Software Solutions
