Augmentation rules and limitations for feature packs on z/OS

Augmenting a profile depends on whether you changed the configuration information, the type of profile, and so on. You must have the correct combination of feature packs in order to add a node, manage clusters, install applications, and manage server templates.

Augmentation rules and limitations

The following table provides additional augmentation rules.

Avoid trouble Avoid trouble: When you create the application server profile, a default server1 process is created. If you delete the server1 process, the profile becomes a custom profile and is governed by the rules for a custom profile.gotcha
Table 1. Rules for profile augmentation
Profiles Supported Not supported
Application server
  • New or updated for this feature pack Creation of a new application server profile that is enabled for the Feature Pack for Web Services.

    You must install the Feature Pack for Web Services onto the Network Deployment product first. When you create the application server profile for the Feature Pack for Web Services, the Feature Pack for Web Services automatically augments the profile with Feature Pack for Web Services capabilities.

  • New or updated for this feature pack User-initiated augmentation of an application server profile

    You cannot create an application server profile and later augment that profile for the Feature Pack for Web Services.

Deployment manager
  • User-initiated augmentation of a Network Deployment deployment manager profile. This action is supported as long as the version of all the federated nodes in the cell is Version 6.1 or higher.

    The Network Deployment deployment manager profile configuration might have changed.

    The Network Deployment deployment manager profile might have been created before or after you applied the feature pack.

  • New or updated for this feature pack Creation of a new deployment manager profile that is enabled for the Feature Pack for Web Services.

    You must install the Feature Pack for Web Services onto the Network Deployment product first. When you create the deployment manager profile for the Feature Pack for Web Services, the Feature Pack for Web Services automatically augments the profile with Feature Pack for Web Services capabilities.

  • Augmentation of a Network Deployment deployment manager profile for a feature pack is not supported if the version of a federated node in the cell is lower than Version 6.1.
Custom If you are running on Version 6.1.0.21 or later, creation of a custom profile enabled for Feature Pack for Web Services.

You must install the Feature Pack for Web Services onto the Network Deployment product first. When you create the custom profile for the Feature Pack for Web Services, the Feature Pack for Web Services automatically augments the profile with Feature Pack for Web Services capabilities.

  • Creation of a custom profile enabled for a feature pack, unless you are running on Version 6.1.0.21 or later
  • Augmentation of a Network Deployment custom profile
Note: The Feature Pack for Enterprise JavaBeans 3.0 does not support the creation and augmentation of custom profiles.
Cell  
  • Creation of a cell profile enabled for a feature pack
  • Augmentation of a Network Deployment cell profile to enable it for a feature pack.

    You must augment a deployment manager profile, and create an application server profile enabled for the feature pack based on the preceding rules in this table.

Unaugmentation rules and limitations

Unaugmentation of feature pack profiles is unsupported on WebSphere Application Server for z/OS.

It is important to backup your configuration filesystem before augmenting.

Augmentation rules and limitations for a mixed-cell environment

When you perform tasks between nodes, or between nodes and the deployment manager, the feature packs must be compatible.

Table 2. Augmentation in a mixed-cell environment
Function Rules
Addition of a node
  • You can add a node to a cell as long as the deployment manager has been augmented with at least the same set of feature packs as the node. The deployment manager might have been augmented with additional feature packs.
  • You can add a node with no feature pack profile to a cell, even though the deployment manager is augmented with some feature packs. However, the node that you add must be at Version 6.1 or higher.
  • You cannot add a node with a particular feature pack profile to a cell, if the deployment manager has not been augmented with that feature pack.
Application installation
  • You can target an application that requires feature pack functionality to an application server on a node that has been augmented with feature packs that contain that functionality.
  • You cannot target an application that requires feature pack functionality to an application server on a node that has not been augmented with that feature pack functionality.
  • You can target an application that does not require feature pack functionality to an application server on a node with or without feature pack augmentation.
Server configuration template
  • You can use the server configuration template to create a server on another node that is augmented with the same feature pack.
  • If you attempt to use a server configuration template to create a server on another node that is augmented with a different feature pack, then the operation fails. The scenario is not supported.
Configuration archive export and import
  • If a configuration contains feature pack capabilities, then exporting a configuration to a configuration archive and importing a configuration from a configuration archive are unsupported. If you run one of the import or export commands of the ConfigArchiveOperations command group against one of these configurations, then the command might complete without reporting an error. No message is displayed when importing or exporting. However, no confirmation exists for imported configuration success.
