Functional Checks

The functional checks are helpful when you need to determine overall operability of the HPOM environment. When the functional checks do not result in the desired outcome, the next step is to plan time for the necessary troubleshooting, configuration changes, or perhaps a patch fix. In order to isolate the problem, ensure that you have collected as much system information as possible. Also, perform the initial data gathering and basic troubleshooting prior to placing a support call, if necessary.

Check the following areas Procedure Notes
Are all of the management server processes running? opcsv Restart the processes. Investigate why the process was not running.
What is the version of the management server software? opcsv -version Verify the current patch level for the management server. Upgrade if necessary.
Are all of the managed node processes running? ovc Check the error log file for possible reasons the process is down. Restart the processes.
What is the patch version of the managed node software? opcagt -version Try to maintain the current patch release.
Check the installed version of .managed node software and the sub-agent components from the management server opcragt –agent_version <node> This is also a quick way to check the communications between the server and the node. If this fails to verify, the node is managed by this server. It may be necessary to restart the processes on the node.
Check the HPOM errors on the HTTPS managed node. tail /var/opt/OV/log/System.txt  
Check the status of the Oracle processes. ps –ef|grep ora If the oracle processes are not running, the HPOM processes will not start.
Verify the Oracle listener. lsnrctl status If the listener lsnrctl start is not running, restart it. The database must be open in order for the listener to start properly. You may need the help from a DBA to restart the database.
Check the HPOM platform background processes and services (NNM). ovstatus -c If the HPOM background processes are not running, HPOM processes will not start.
Verify hostname resolution from the server. nslookup <node> The HPOM platform utilizes nslookup <local_server_name> name resolution lookup services, this information must be correct within the DNS, NIS or local host file.

Note: The command nsquery is becoming more useful for hostname or IP lookups. It provides more detailed information.

Verify hostname resolution from the managed node. nslookup <server> nslookup <local_node_name>  
Check network connectivity from the server. ping <node> ping tests may indicate certain network delays that can be viewed with HPOM as a node down. Intermittent ping failures should be investigated and resolved.
Check network connectivity from the managed node ping <server> If the node is unable to ping the server; messages are buffered until the server is available.
Check the name resolution service configuration file. more /etc/nsswitch.conf Verify the search order. If using multi-homed hosts, see #17.
Is the node multi-homed? Add an entry with the second IP_ADDRESS HOSTNAME into a file that you create on the server called /etc/opt/OV/share/conf/OpC/mgmt_sv/ The file has the same format as the /etc/hosts file. After the file is created restart the server processes. Any changes to the file require process restart.
Operator and Administrator login. ps -ef|grep ui ps -ef|grep opcuiwww Each operator (including the administrator) should have a unique login account for security purposes.
Login to HPOM using the operator account to ensure that the environment displays the correct information based upon the operators responsibilities.    
Check the Oracle environmental variables cat /etc/opt/OV/share/conf/ovdbconf  
Check the Oracle environmental variable within the user Oracle shell environment. su – oracle env|grep ORA
Check for all the environmental variables within the user oracle shell environment su – oracle

env > /tmp/ora_env.out

more /tmp/ora_env.out
System environment variables are also important, such as the PATH, MANPATH, LANG, and so on.
Check connectivity to the Oracle database
  1. su – oracle
  2. sqlplus opc_op/
  3. Exit
Note: It may be necessary to check with a DBA to gain access to the database using the privileged user accounts.
Check remote connections to the database.
  1. su – oracle
  2. sqlplus opc_op/opc_op@ov_net
Check the error logs.    
Clean up pending policy distributions. ll /var/opt/OV/share/tmp/OpC/distrib

rm /var/opt/OV/share/tmp/OpC/distrib/*

If the distribution failed, a message will periodically appear in the message browser; remove the files from the distribution directory.
Check the integrity of the queue files /opt/OV/contrib/OpC/opcqchk <queue_file> If this program presents a menu and basic operations can be performed the queue file is OK.
Test message data flow in general opcmsg a=a o=o msg_t=test If the message appears in the browser message flow is OK.
Messages should appear in the browser of the assigned operator if not check the following:
  1. Check the operator's responsibilities
  2. Use local logging for the policy to check whether
    1. the agent actually recieves the input event.
    2. the event is suppressed or not
    3. rule out duplicate message suppression and message/event correlatoiin.
    4. check history browser, message could have been configured to go directly to history tables in the database.
  3. Review policy inventory on the managed node using the command ovpolicy or opcpolicy.
  4. Use the opcpat command to verify pattern syntax is correct. See the man pages for use of the opcpat command.
Test action execution. Use command broadcast and run a command (i.e. hostname) If successful actions work in general
Verify agent status opcragt <node_name> This displays agent status and tests basic connectivity
Test basic HTTPS connectivity bbcutil -ping <node> Execute the command on the managed node
Test HTTPS agent security certificates ovcert -list  
Utilize the trace facility If necessary to further investigation configure XPL tracing Refer to the Tracing Concepts and Users Guide for more information about XPL tracing and logging.
