This test auto-discovers the owners of SHM segments, monitors the usage of each segment, and reports the number of SHM segments owned by each owner, the number of segments mapped to/not mapped to processes, the count of processes attached to the segments, the total size of the SHM segments owned by each owner, and the number of SHM segments removed, cleared, and locked for every owner. This way, the test points to those owners with SHM segments that are not even mapped to any process, leave alone being used; thus memory segments that are candidates for removal/release can be identified.

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• By default, the REPORT BY flag is set to Owner. This implies that, by default, the test metrics for every message queue owner on the target server. You can set this flag to Total, if you want the test to report metrics for the Total descriptor alone; in this case, the test will aggregate measures across all the message queues on the server. Alternatively, you can pick the Owner and Total option. In this case, the test will report metrics per owner and also for the Total descriptor.

• The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

• To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the DETAILED DIAGNOSIS capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

  The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
