Continued from Installation of HPOM agent from local files

  1. Step 2: create a tar file for the agent
  2. Step 3: transfer the tar file to the server using ftp, scp, or ssh and untar it
  3. Step 4: Run opc_inst with parameters -srv and -cert_srv
  4. Step 5: verify the status of the agent
  5. Step 6: Create certificates and grant them on the HPOM server

Node: We assume that you already created a node using the command:

opcnode -add_node \
         node_name=usa12.firma.com \
         node_label=usa12 \
         group_name=linux \
         layout_group=linux \
         ip_addr=10.10.10.111 \
         net_type=NETWORK_IP \
         mach_type=MACH_BBC_LX26RPM_X64

Step 2: create a tar file for the agent

Download ISO image for agents from HP and create tarball.

It is important to do it each time as agent can be patches since the last time you create the tarball.

See Adding nodes

The directories for agents for supported platforms are as following

/var/opt/OV/share/databases/OpC/mgd_node/vendor/hp/pa-risc/hpux1100/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/linux/x86/linux26/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/linux/x64/linux26/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/linux/ipf64/linux26/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ibm/rs6k64/aix5/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ibm/rs6000/aix5/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/sun/x86/solaris10/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/sun/sparc/solaris7/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ms/x86/winnt/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ms/x64/win2k3/A.08.10.160/RPC_BBC
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ms/ipf64/win2k3/A.08.10.160/RPC_BBC

For Linux 64 bit one should use

 /var/opt/OV/share/databases/OpC/mgd_node/vendor/linux/x64/linux26/A.08.10.160/RPC_BBC

For AIX 5.3 one should use

    /var/opt/OV/share/databases/OpC/mgd_node/customer/ibm/rs6000/aix5/RPC_BBC

Step 3: transfer the tar file to the server using ftp, scp, or ssh and untar it

For example:

/var/opt/OV/share/databases/OpC/mgd_node/customer/sun/sparc/solaris7/RPC_BBC
tar cvf ../omu_solaris_agent.tar *
cd ..
gzip omu_solaris_agent.tar
scp omu_solaris_agent.tar.gz node_to_be_provisioned:/tmp

On target server you need to create a directory in /tmp and untar the file into it

mkdir HPOM_agent
cd HPOM_agent
tar xvf ../omu_linux64_agent.tar

 Step 4:  Run opc_inst command with parameters -srv and -cert_srv

Depending on you method of transfer of files you need to verify that opc_inst is executable and if necessary change permissions on it.

chmod 755 opc_inst
./opc_inst -srv  omu_server	-cert_srv omu_server 

For example:

./opc_inst -srv nti106 -cert_srv nti106

Those two parameters (-srv and -cert_srv) are very important and without them agent will be installed in "portable mode" which need to be activated with special command.

Those two parameters (-srv and -cert_srv) are very important and without them agent will be installed in "portable mode" which need to be activated with special command.

If you try to run installation script without parameters and then try to start the agent you will get the following situation. First you will find that the agent did not start after the installation. Attempt to start it manually will give something like opcmsga service failed.

export PATH=/opt/OV/bin:$PATH
root@testnode:/tmp/ HPOM  # ovc -start
root@testnode:/tmp/ HPOM # /opt/OV/bin/OpC/opcagt -status
coda OV Performance Core COREXT (21966) Running
opcacta OVO Action Agent AGENT,EA (21997) Running
opcmsga OVO Message Agent AGENT,EA Aborted
opcmsgi OVO Message Interceptor AGENT,EA (21982) Running
Could not contact Message Agent to query buffering state.

Step 5: Verify the status of the agent

After the installation complete (it usually takes several minutes) you need to verify the status of the agent

/opt/OV/bin/OpC/opcagt -status
coda        OV Performance Core                 COREXT       (1603)   Running
opcacta     OVO Action Agent                    AGENT,EA     (1486)   Running
opcmsga     OVO Message Agent                   AGENT,EA     (1487)   Running
opcmsgi     OVO Message Interceptor             AGENT,EA     (1605)   Running

Generally agent should be running after the installation without any crashed daemons. It is not running or some daemons fail that's the sign of trouble. You can try to start the agent manually using command

ovc -start 

Note: Put the path in front or add /opt/OV/bin/:/opt/OV/bin/OpC/ to the PATH before issuing the command.

Step 6: Create certificates and grant them on the HPOM server

After that you need to check if certificates are available and if status is "pending" you need to grant them using Admin GUI:

/opt/OV/bin/ovcert -list

To check the status of the request

/opt/OV/bin/ovcert -status

If there is no pending certificate request you need to execute

/opt/OV/bin/ovcert -certreq

and repeat the check of the status using /opt/OV/bin/ovcert -status

If status is pending you can grant the request either using command line tools or the Admin UI.

Then verify that the certificates are available using the command on the node:

# /opt/OV/bin/ovcert -list

After that you should check if the node is listed with certificate installed in view mode of the AdminGUI. If not verify communications using command

# /opt/OV/bin/OpC/opcagt -status usa12
coda        OV Performance Core                 COREXT       (1603)   Running
opcacta     OVO Action Agent                    AGENT,EA     (1486)   Running
opcmsga     OVO Message Agent                   AGENT,EA     (1487)   Running
opcmsgi     OVO Message Interceptor             AGENT,EA     (1605)   Running

You can also send a test message to the server by deploying opcmsg policy and using the command opcmsg.
