Default Parameters for UnivDBSessTest

At configured intervals, this test reports the session load and overall session usage by the users of the database server, and warns administrators of a probable overload condition on the server. Additionally, the test also reports the number and type of sessions launched per user, and thus reveals which user(s) has contributed the most to the overload and the type of sessions responsible for the same. The details of users and their sessions are also revealed as part of detailed diagnostics. Using these useful problem pointers, administrators can decide between killing idle sessions to reduce the load on the server or increasing the session limit to accommodate more number of sessions.

This page depicts the default parameters that need to be configured for the UnivDBSessTest.

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

  • This test uses UniVerse shell commands to pull the desired metrics from the server. To enable the test to run these commands, provide the path to the bin folder of the UniVerse install directory. For example, for a Windows installation of UniVerse, the UNIVERSE SHELL PATH can be: C:\U2\UV. For a Unix installation, your specification can be: \usr\uv

  • U2 DBTools include Eclipse-based tools for programming and administration. Eclipse is an integrated development environment (IDE). It contains a base workspace and an extensible plug-in system for customizing the environment. Eclipse is written mostly in Java and its primary use is for developing Java applications. Where Eclipse IDE is installed, the eG agent should be configured to use the Eclipse environment for executing the UV shell commands. In this case therefore, type the full path to the Eclipse home directory. By default however, the ECLIPSE PATH is set to none, indicating that by default, the eG agent runs the commands from the UniVerse shell only and not Eclipse.

  • This test reports detailed diagnostics for the Interactive sessions and Background sessions measures. By default, the details of these sessions - eg., the user who launched the sessions, the commands last executed in the sessions, and the terminal that the user logged in from, will be reported as part of detailed diagnosis. The login time of the user will however, not be reported as part of the detailed measures by default. This is why, the INCLUDE LOGGED IN TIME flag is set to No by default. To make sure that the detailed diagnosis includes the login time of the user as well, set this flag to Yes.

  • 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.

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

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
