LiveView Metadata Store

Shared resources between LiveView servers include:

You must configure each server with the same storeType type in a LiveView Engine configuration file.

The example below defines the storeType property with a value of JDBC and uses the jdbcDataSource property to define a source called myJDBCSource. If you define a JDBC data source in the engine configuration file, you must use the same JDBC data source value in a JDBC configuration file of HOCON type (see below).

Unlike the JDBC case, setting the storeType to TRANSACTIONAL_MEMORY does not require additional metadata store configuration.

name = "myldmengine"
version = "1.0.0"
type = "com.tibco.ep.ldm.configuration.ldmengine"
configuration = {
  LDMEngine = {
    metadataStore = {
      storeType = "JDBC" 
      jdbcDataSource = "myJDBCSource"        
      jdbcMetadataTableNamePrefix = "LV_CLUSTER1_"       
      }
    }
}

Configure a EventFlow JDBC Data Source Group configuration file when the LiveView engine configuration file defines a JDBC storeType (see above).

A JDBC configuration file can define multiple JDBC data sources. To enable resource sharing between LiveView servers, your JDBC configuration file must contain at least one data source, and the value must match the value defined in the engine configuration file. This example defines one JDBC source called myJDBCSource.

name = "mydatasource"
version = "1.0.0"
type = "com.tibco.ep.streambase.configuration.jdbcdatasource"
configuration = {
  JDBCDataSourceGroup = {
    associatedWithEngines = [ "javaengine", "otherengine[0-9]" ]
    jdbcDataSources = {    
      myJDBCSource = {    

The Role to Privileges Mappings configuration file is required to allow importing and exporting resources between LiveView nodes. Your configuration file must define a user that includes the following privileges:

In practice you often define users with multiple LiveView privileges, depending on user role. The following example defines a user with all LiveView privileges, which includes both privileges described above.

name = "my-role-mappings"
version = "1.0.0"
type = "com.tibco.ep.dtm.configuration.security"
configuration = {
 
  RoleToPrivilegeMappings = {
    privileges = {
      admin = [
        {
          privilege = "LiveViewAll"
        }
      ]
    }
  }
}
