In HPOM 9 Policies can have multiple versions (version control), and are organized in a tree-like structure. See “Policy Versions” on page 87 and the HPOM Concepts Guide for more information. Policies can also contain category assignments linking them to scripts. This is useful, for example for message policies.
A policy container represents a set of policies with the identical name and the type, but different versions. All policy versions in the policy container are unique. Some operations can be performed on policy containers, which means that they are performed on each policy in the container. Each container has a unique ID that is shared by all the policies in that container. Containers are identified by their names and types, or by their IDs. Policy Types It is possible to have multiple types of policies on the management server mapped to the same policy type on the managed nodes. Therefore, during the policy type registration you can specify the type by which the policy is classified on the managed node. If this type is not specified, the policy type name registered on the management server is used instead. In this case, if there are no corresponding consumers on the managed node, the policies will nevertheless be deployed, but ignored afterwards.
With HPOM 9.0x, it is possible to have multiple versions of policies stored on the management server. Having multiple versions of policies on the HPOM 9.0x management server enhances the flexibility in operating with policies and policy groups, and allows simplified interoperability between HPOM on Unix, Linux, and Windows platforms. All policies have version numbers. A version number consists of two digits with the format major.minor, for example, 1.0. Major digits can be reserved for the specified purposes, for example, for SPIs release tracking. The version of all newly created policies is set to 1.0, while the version of all default policies delivered with HPOM 9.0x is 9.0.
It also ensures the following:
When the policy content is modified, the minor digit of the policy version number is automatically incremented, for example, from 1.0 to 1.1. If the new version already exists, the next available value is chosen, for example 1.2. To learn how to overcome the conflicts between the versions, see “Managing Conflicts between Policy Versions” on page 259.
NOTE A change in the policy header (for example, changing the policy description) does not result in the creation of a new policy version. The policy version can be replaced according to your preferences by using the opcpolicy command-line tool. The policy version numbers can also be changed without the need to modify the policy content. This is especially useful when aligning the policy versions that are released together. For usage details, see the opcpolicy (1M) manpage. For more information about the available APIs, see the HPOM Developer’s Reference.
NOTE The new version number creation results in the creation of a new policy, even if the content is unchanged. The new policy has a new version UUID, but the container ID is same as before. On the other hand, changing the policy name results in a new object in the database with a new version UUID and a new container ID.
Only one version of each policy can be installed on a managed node. When deploying a new policy version to a managed node, the new policy version replaces the existing version, regardless of its version number. This is because both versions use the same container UUID that is used on the managed node to identify the policies. Managing Conflicts between Policy Versions Policy versions come into conflict when the version number of a policy that you intend to assign already exists in the database. The following modes are available for managing conflicts between versions:
There are two types of checksums:
A policy type is an agent-known string (for example: monitor, le, trapi, and so on) that also includes the UUID and the syntax version.
With HPOM 9.0x, it is possible to have multiple versions of policiesstored on the management server. Having multiple versions of policies onthe HPOM 9.0x management server enhances the flexibility in operatingwith policies and policy groups, and allows simplified interoperabilitybetween HPOM on Linux and Windows platforms.❏ “Changing the Policy Version” on page 87
❏ “Migrating HPOM 8.xx Policys to HPOM 9.0x Policies” on page 88 For more information about the concepts of policy versions and theorganization of the policy-group hierarchy, see the HPOM ConceptsGuide.
All policies have version numbers. To replace a particular policy version, use the opcpolicy command with the -update parameter as follows:
# opcpolicy -update version=<policy_version>
You can also upload and download specific versions of a policy andinstruct HPOM what to do if a version already exists. For more information about the opcpolicy command and the -update parameter, refer to the opcpolicy(1m) reference page. The policy version numbers can also be changed without the need tomodify the policy content. This is especially useful when aligning thepolicy versions that are released together. Refer to the opcpolicy (1M)HPOM Configuration reference page for more information about command options.
NOTE The new version number creation results in the creation of a new policy, even if the content is unchanged. The new policy has a new version UUID, but the container ID is same as before. On the other hand, changing the policy name results in a new object in the database with anew version UUID and a new container ID.
