As the Product Manager for a number of products including Oracle Application Management Pack for Oracle Utilities, the Oracle Enterprise Manager plugin for managing Oracle Utilities Application Framework product there are always a number of requests that come across my desk that need clarification. I wanted to post a few responses to some common issues we are seeing in the field and how to address them.
- Read the Installation Documentation. This is obvious but the installation documentation not only talks about the installation of the pack but also what features to enable on the Oracle Utilities Application Framework to maximize the benefits of the pack. For customers on older versions of the Oracle Utilities Application Framework, some of the advanced features of the pack are not available as those versions of the Oracle Utilities Application Framework do not exist. For example, most of the metrics were added in Oracle Utilities Application Framework 4.x.
- Clustering Support Changes. In earlier versions of Oracle Utilities Application Framework with older versions of Oracle WebLogic, to use clustering you needed to use the localhost hostname. Whilst this worked for those versions (and has been used with later version), Oracle recommends to use the actual host name in the configuration and in particular for the JMX integration used by the Oracle Utilities Application Framework. Using localhost in the host name may prevent Oracle Enterprise Manager and the pack recognizing the active ports and will result in the target not being recognized.
- Native Install Transition. A few years ago, the Oracle Utilities Application Framework transitioned to use Oracle WebLogic natively rather than the original embedded mode which was popular in legacy versions of the product. The main reason for moving to native mode was to allow customers full flexibility when using the Oracle WebLogic Domain so that the license value was increased and advanced configuration was supported. To support that transition a decision was made in respect to the pack:
- Embedded Mode Customers. It is recommended that customers still on the old embedded mode that have not transitioned to a native installation, yet, use the Start / Stop functionality on the Oracle Utilities targets to manage the availability of Oracle Utilities targets.
- Native Mode Customers. Customers who have transitioned to the native installation are recommended to use the Oracle WebLogic targets to start and stop the product (as this is one of the benefits of the native mode). It is NOT recommended to use the start and stop functionality on the Oracle Utilities targets during the transition period. The current release of Enterprise Manager and the Application Management Pack for Oracle Utilities cannot manage cross targets at the present moment.
Essentially, if you embedded mode then use the start/stop on the Oracle Utilities targets, if you are native use the start/stop on the Oracle WebLogic targets.
