Component configuration recommendations for horizontal scaling
Based on the recommended hardware sizes, 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.
Use the following table in conjunction with the recommendations provided in the horizontal sizing recommendations.
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 re-start 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.

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. Notes:
