Removal of policies

A single policy, as well as an entire container, can be removed from the database by using the opcpolicy command line tool. To delete a policy, it has to be uniquely identified by either its name/type/version combination or by its UUID.

If just policy name and type are provided, the entire policy container is deleted.

NOTE Deleting the policy also results in deleting all its assignments.

Following is an example of deleting a policy container:# opcpolicy -remove pol_name="Test policy" pol_type=Logfile_Entry

Policy groups are deleted by using -del_group option of the opcpolicy command line utility. For example, to delete the policy group ”Testgroup”, use the following command:# opcpolicy -del_group pol_group="Test group"

For more information about command options, refer to the opcpolicy(1M)reference page.Downloading Policies You can download policies using the -download option of the opcpolicy command . If a policy version is omitted from the command line arguments, the entire container is downloaded. Example of policy download using the opcpolicy command line tool:

# opcpolicy -download pol_name="Oracle messages" pol_type="Open_Message_Interface" version=1.0 dir=/tmp

For more information about the parameters available with the opcpolicy command, refer to the opcpolicy (1M) reference page.

Dear Experts... i need your advice for this following question

I have a management server (trial licence), and it's already expired, but there are templates,commands, and so on still left on a specific node, i need to remove them for many purposes, so..

1. How to assign (before distribute)template by command line ? 2. How to delete a specific template already assigned to specific node ? (by command line) 3. Does each template assigned to a node will be come a specific file in certain directory inside the node ? 4. How to delete specific template and its related command, monitor and action ? (by command line)

Kindly need your advice.., points available

Jeroen Peereboom :

Hery,

use opcnode for template to node assignments.

3. No, on the managed node there are files like 'le' for all logfile encapsulators assigned to the node, 'monitor', 'msgi' and so on.

In stead of removing assignments, you may just stop and kill the agent on the node (opcagt -stop; opcagt -kill, or stop the agent Services using the Windows management console) and disable startup when the system restarts (On Windows, make the service manual startup (or disabled), on Unix check the /etc/init.d, rcx.d and so on).

HtH,

JP

Jeroen Peereboom:

L.S. aasuming you assigned the templates to the node directly (not via a Node Group):

/opt/OV/bin/OpC/utils/opcnode -list_ass_templs node_name=<node_name> net_type=NETWORK_IP

will tell you which templates have been assigned to your node.

Suppose you want to remove a logfile template: /opt/OV/bin/OpC/utils/opcnode -deass_templs templ_name="<template_name> templ_type="LOGFILE_TEMPLATE" node_name=ns60as033 net_type=NETWORK_IP

After this, you can distribute the new configuration to you managed node: opcragt -distrib -templates <node_name>

To be honest, I see no reason to remove these files. They only occupy some disk space. Better leave them on the managed node.

However, a dirty (risky) way for removing actions, commands, monitors: On the management server in /var/opt/OV/share/databases/OpC/mgd_nodes are files for each platform. Go to your platform specific directory (for example customer/hp/pa-risc/hpux1100/actions/), remove some files) and use opcragt to distribute: opcragt -distrib -force -actions <node_name)

Of course, this is a dirty method and be sure to make a backup of all these files (tar?) and restore them afterwards.

Alternatively you may use ovdeploy or opcdeploy to directly remove files on the managed node. I don't use it often, so check the man page. Or just have someone login on the managed node and remove the files.

But as said before, why remove them?

By the way, your JAVA GUI is still available...

HtH,

JP.

Pat Campbel:

You can use the ovpolicy command to remove templates. Read the man page for this command; there is a -remove option to remove one or more policies

Pat Campbell Sep 3, 2008 21:03:35 GMT 3 pts

Really no need to remove the files to measure performance, just disable the templates or stop the processes.

To disable the SPI, use "opctemplate -d <template_name>" or opctemplate -d -all, to disable all templates.

To eliminate the OVO agent, "opcagt -kill".

To eliminate ovpa, "ovpa stop".

Hery Mulyawan Sep 3, 2008 06:31:27 GMT N/A: Question Author

Hi JP,

Thanks for your advice, but let me make it more precise, i have HPOM 8.x on HP-UX.., i have distributed SPI X to a node, there are ovo agent and OVPA inside the node, and also other application (some kind of charging gateway), i need to remove the SPIs Template from the node and remain the OVO and OVPA installed&running on it,

so my purpose is to remove the SPI X template, and also the command, monitor related to it, I cant login to Motif GUI due to licence issue.

Do you have any idea JP ?

Hery Mulyawan:

Hi JP.

I understand your confusion, our concern is to measure the resources consumed by OVO, while the application itself (charging gateway) has already consumed a lot of resources,and very sensitive,also it run heavily, so the charging team would like to know their application's performance with this following scenario : 1. with OVPA+OVO agent+SPI are running 2. With OVPA+OVO are running 3. None of them are running

/opt/OV/bin/OpC/utils/opcnode -list_ass_templs node_name=<node_name> net_type=NETWORK_IP ==> it's not working, "Retrieving information for 'TEMPLATE_LIST' from the OVO database failed."

i Prefer to delete the "command" etc directly from the node @ instrumentation directory, so the impact will be on the managed node. JAVA GUI is not working also, for now i have shut the agents down.. and the test are being made...

Is there any command to manually remove or delete templates from node? opctemplate can only disable.

Hello

There is no good manual way of deleting policies from a node managed by OVOW.

If you really want to do this - you can delete the folders that contain the policies from the node. The only catch is it is an all-or-nothing deletion of policies (by type) from the node. If you are interested you can do this by following:

1. Delete all files in directory "%OvAgentDir%\conf\ConfigFile\policies" to remove all ConfigFile policies from the node.

2. Delete all files in directory "%OvAgentDir%\conf\svcdisc\policies" to remove all Service Auto-Discovery policies from the node.

3. Delete all files in directory "%OvAgentDir%\conf\nodeinfo\policies" to remove all Node Info policies from the node.

4. Delete all files in directory "%OvAgentDir%\conf\mgrconf\policies" to remove all Flexible Management policies from the node.

5. Delete all files in directory "%OvAgentDir%\conf\OpC\vpwin" to remove all other policies from the node.

Note that this only clears policies from the node side. If the OVOW server knows about policies on this node then you will have a mismatch (that you will have to fix on server side).

Hope this helps. Regards Ram

Well, thanks for that step by step. I saw that when there are policies in OVOW policy view, but policy is not in the managed node and want to Remove policy from node policy view, I get MMC snap-in error. How can I fix policies on the OVOW side?

I will be glad to delete ALL policies and redeploy the new ones.

Ram Jun 18, 2007 14:32:39 GMT 9 pts

Hello

I am assuming that OVOW server is still managing the node - it is just that there is a mis-match in policy inventory between what the server sees and what is on the node.

You can try following and see if it helps:

1. Use OvInternals tool called "redistpolicies.vbs" and this will deploy the policies that are in OVOW policy inventory to the node.

2. Once the policy inventory in the node and server matches then you can use the OVOW Console and run the "Remove from node" on the policies.

Hope this helps. Regards Ram

Rem-8 Jun 19, 2007 03:54:29 GMT N/A: Question Author

Are policies such as Measurment Thresholds also in D:\Program Files\HP OpenView\Installed Packages\{790C06B4-844E-11D2-972B-080009EF8C2A}\conf\OpC\vpwin ?? If I delete content and use ovinternals tool I will have managed nodes with non of the policies? Clear like an air in Antarctica?

Ram Jun 19, 2007 07:25:03 GMT Unassigned

Hello

You are right - policies such as measurement threshold, WMI and logfile encapsulator are in the %ovagentdir%\conf\opc\vpwin folder.

If you remove all the files from the folders that I had listed in the last posting then it should clear all the policies from the node.

Hope this helps. Regards Ram
