Modifying the configuration files

This topic provides information about how you can modify the product configuration files to customize particular default settings.

This topic contains the following information:

Changing property definitions

The product's configuration information, including the default and customizable settings, are stored in the configuration files. These files come packaged with the product installation and usually end with the .properties extension, .yml extension, or .conf extension:

The .properties file stores information for various aspects of the product configuration, including data collection, product user-interface settings, Search settings, and Indexer settings.
The product stores the collected data in time-based indices. The size of each of the indices is defined by the properties in the .yml file.
The .conf files store the initial and maximum memory settings for various components. For more information, see Component-configuration-recommendations-for-horizontal-scaling.

Note

Any change that you make in the customIndexstrategies.yml file must be reflected in both locations (the Collection Station and the Search), as described in the following table.

You can navigate to the appropriate custom folder and edit the appropriate file to modify existing properties or add new properties related to one of the product aspects that you want to change. While modifying a property, ensure that the property is uncommented. The properties that you modify in the custom folder take precedence over those stored by default in the conf folders.

Warning

To avoid future problems, do not modify the default property definitions.

The location paths provided in the following table (except the Collection Agent) must be preceded by the following environment variable, as appropriate:

Windows: %BMC_ITDA_HOME%
Linux: $BMC_ITDA_HOME

The Collection Agent location path must be preceded by the following environment variable, as appropriate:

Windows: %PATROL_HOME%
Linux: $PATROL_HOME

Navigate to the following customizable locations, as applicable, to change the default values of the properties available:

Component	Default location	Customizable location
Collection Station	\station\collection\conf\agent.properties	\station\collection\custom\ conf\agent.properties
Collection Station	\station\collection\conf\indexstrategies.yml	\station\collection\custom\ conf\customIndexstrategies.yml
Collection Agent (standalone)	\agent\collection\conf\agent.properties	\agent\collection\custom\ conf\agent.properties
Collection Agent (for BMC PATROL infrastructure)	\bww\udc\conf\agent.properties	\bww\udc\conf\agent.properties
Console Server	\conf\server\ olaengineConfig.properties	\custom\conf\server\ olaengineCustomConfig.properties
Search	\conf\server\searchserviceConfig.properties	\custom\conf\server\ searchserviceCustomConfig.properties
Search	\conf\server\indexstrategies.yml	\custom\conf\server\ customIndexstrategies.yml

Changing directory location for indexed data

By default, the data collected and indexed is stored at the following location:

Windows: %BMC_ITDA_HOME%\data\indexer
Linux: $BMC_ITDA_HOME/data/indexer

Tip

In a few scenarios, you might want to change the directory location for the indexed data; for example:

If you want to store the Indexer data on a separate disk to enable data back-ups or track the data size
If you want to distribute the disk I/O between the operating system of your computer and the product data collection+search mechanism.

Note

If you change the default directory location of the Indexer, then after uninstalling the product, you must manually delete the new directory.

To configure the Indexer location path

Stop all product services. For more information, see Starting or stopping product services.
Create a backup of the indexer.conf file by navigating to the following location:
- Windows: %BMC_ITDA_HOME%\conf\services
- Linux: $BMC_ITDA_HOME/conf/services
In the indexer.conf file, locate the following line, change the value to the desired data location path, and save the file:
wrapper.java.additional.10=-Des.path.data="%BMC_ITDA_HOME%"/data/indexer
Copy the BMCINDEXERCLUSTER directory along with all of its sub-directories and files, at the following location to the location specified in step 3:
- Windows: %BMC_ITDA_HOME%\data\indexer
- Linux: $BMC_ITDA_HOME/data/indexer
Restart all product services. For more information, see Starting or stopping product services.

Changing directory location for the Configuration Database data

By default, the Configuration Database data is stored at the following location:

Windows: %BMC_ITDA_HOME%\data\configdb
Linux: $BMC_ITDA_HOME/data/configdb

Tip

You might want to store the configuration database data on a separate disk and perform regular backups to avoid problems related to hardware crashes.

To configure the Configuration Database location path

Stop all product services. For more information, see Starting or stopping product services.
Create a backup of the configdb.conf file by navigating to the following location:
1. Windows: %BMC_ITDA_HOME%\conf\services
2. Linux: $BMC_ITDA_HOME/conf/services
In the configdb.conf file, locate the following line, change the value to the desired location path, and save the file:
wrapper.app.parameter.7=file:../../data/configdb/ITDADB
Note
In the preceding property value:
- ../../data/configdb/ refers to the directory location of the database files that you need to change.
- ITDADB refers to the prefix of the database files that must not be changed.
Copy the contents of the ../../data/configdb/ file to the new directory specified in step 3.
Restart all the product services. For more information, see Starting or stopping product services.

Changing the polling batch and time setting for data collectors

When you start the product, by default a batch of 10 data collectors are polled for starting. By default, every next batch of 10 data collectors are polled after a time difference of 1 second. This is helpful when you have a large number of data collectors in your environment. BMC recommends you to use the following table as a guide to decide when you want to increase the collection thread pool size. This table provides information about data collectors with one minute polling interval. If the scheduled polling falls behind the one minute interval, then you need to increase the collection thread pool size.

collection.thread.pool.size	Number of data collectors
10	375
20	750
30	1125
40	1500

To change the batch and time setting

Navigate to the agent.properties file, as described in the Changing property definitions table.
To change the batch setting, add the collection.thread.pool.size property with the desired value; for example, collection.thread.pool.size=50.
To change the time setting, add the collection.ifmultiple.startup.delay property with the desired value (in seconds); for example, collection.ifmultiple.startup.delay=5.
(Optional) To start all data collectors together (without any time difference) add the property collection.ifmultiple.startup.delay.enabled=false.
