Component configuration recommendations for single-server sizing

Based on the single-server sizing recommendations, you might need to change the configurations of various product components to make optimum use of available resources.

The following table provides a list of the configuration properties, their locations, and the recommended values for the properties for each setup. The test setup values are default values of the properties described.

In the table, the configuration location paths must be preceded by one of the following environment variables:

  • Windows: %BMC_ITDA_HOME%
  • Linux: $BMC_ITDA_HOME

Note

When you change any of the following properties, ensure that you restart the corresponding service for the particular component and any dependent services. For example, the wrapper.java.initmemory property defines the initial memory required for the Indexer, so when you change this property value, ensure that you re-start the Indexer.

For more information about starting or stopping services and service dependencies, see Starting or stopping product services

Ensure that you make the same configuration changes for components of the same type. For example, if you change certain configurations for the Indexer, and you have multiple instances of Indexers deployed, ensure that you make the change for all Indexers in your environment.

Oops, it seems that you need to place a table or a macro generating a table within the Table Filter macro.

To change this property, you need to run the configureindexsettings CLI command .

These changes are required only for the master Indexer installed on the primary node.

Tip: A shard is a way of splitting a large amount of data into multiple portions, where each portion is called a shard. Shards also provide a way of evenly balancing data indexed across multiple Indexer instances.

Note: Any changes regarding the number of shards are applied only to the newly created indices.

At the time of adding multiple Indexers in your environment, this property must be adjusted to a lower value. Doing this can enable quicker recovery if any of the Indexer nodes go down.

    Please be aware that these two settings:

    wrapper.java.initmemory wrapper.java.maxmemory

    in the custom\conf\services\collectionstation.conf configuration file MUST be set to the same value. If they are set to differing values the collection station will not run. The information listed above for these settings setting them to different values appears to either be a typo, or is incorrect.

      Hi Louis Duke,

      Thanks for your feedback. The values for the two attributes wrapper.java.initmemory and wrapper.java.maxmemory have been updated for the collectionstation.conf file. Hence closing the comment.

      Regards,

      Shreya Adiga
