TimesTen Instance Configuration File

1 TimesTen Instance Configuration File

The TimesTen instance configuration file contains TimesTen instance configuration attributes and their values.The timesten.conf file is located at timesten_home/conf/timesten.conf. Each line of the configuration file consists of one name=value pair.

The following table contains all the TimesTen configuration attributes, descriptions, default values, and data types.

Note that some configuration attributes have a corresponding connection attribute. In these cases, you can override the setting of the configuration attribute in the server timesten.conf file by setting the connection attribute in the database DSN definition. Similarly, you can override the setting of the configuration attribute in the client timesten.conf file by setting the connection attribute in either the client DSN definition or the connection string.
