Configure EM Messaging Settings

The Enterprise Manager (EM) Primary administration tool for all of the managed servers deployed in an enterprise, including those deployed both in the Data Center and in remote geographical locations (or sites). Messaging settings allow the Enterprise Manager to send configuration messages to the servers it manages. The Enterprise Manager Agents on the servers request these configuration changes from Enterprise Manager. (For more information on configuration messages, see Handling of Configuration Changes by the Enterprise Manager.)

Change these settings only under the instruction of an authorized support representative. Changing these settings can cause applications to stop functioning.

To configure EM Messaging settings:

  1. Go to System Management Module that allows performing suite-wide system management activities from a single, Web-based application, the Enterprise Manager.. Under General Settings, select General.

  2. Scroll down the General Settings window until EM Reliable Messaging displays, and then click the arrow to show all fields.

  3. Complete the fields according to the following, or accept the defaults:

    Item

    Description

    Maximum Number of Threads

    Type the maximum number of threads available to send Enterprise Manager Agent Web application installed on every system server that communicates with the Enterprise Manager regarding any configuration changes or alarm messages for the relevant server. (EMA) requests. Since each request is done on a separate thread, this number is the maximum number of concurrent EMA requests. The default setting is 5.

    If the Enterprise Manager takes too long to distribute configuration changes in large environments with many servers, try increasing this setting to 10.

    Minimum Number of Threads

    Type the minimum number of threads available to send EMA requests. The default setting is 1.

    Thread Execution Delay

    Choose the delay time (in milliseconds) between a thread completing the execution of a task and starting the execution of a new task. Valid values are 0, 50, 150, 200, 250, or 300. The default setting is 300.

    Message Data Purge Interval (days)

    Type the interval (in days) to check for message data that should be deleted. The default setting is 1.

    Message Job Purge Interval (days)

    Type the interval (in days) to check for message jobs that should be deleted. The default setting is 1.

    Message Job Age (days)

    Type the age of the message job (in days) before it can be deleted. Any message job older than the number of days and that is completed is purged from the database. The default setting is 30.

    Scheduled Job Timer Interval

    Type the interval (in milliseconds) used to check for jobs that have been scheduled and are ready to be sent. The default setting is 60000.

    Client Timeout

    Type the amount of time (in milliseconds) that the adapter waits before timing out a client request from Enterprise Manager. This value is used to prevent unresponsiveness while the adapter is processing large configuration messages. Once a timeout has occurred, the Configuration Status screen displays the status of the message. The default setting is 15000.

    Note: All fields are mandatory and values typed must be greater than 0.

  4. Click Save.

  5. Restart the application server for changes to take effect.
