Required Attributes

 

Table 22: Stream Driver Required Attributes 

Attribute and Type

Type

Description

TD_BUFFER_MODE

varchar

Indicates which type of Stream method is used.

Valid Settings:

  • Default value is No.
  • Must be set to Yes when using the block Stream feature.
  • TD_INSTANCE_NUM

    integer

    Provides the instance number of the current instance. Required when using multiple instances of the same driver in a master-slave environment.

  • If the current instance is the master instance, then the instance number should be one.
  • If the current instance is a slave instance, then the instance number should be a value greater than one.
  • TD_LOG_TABLE

    varchar

    Provides the name of the restart log table for restart information. Each Stream driver job needs to use its own restart log table if multiple Stream driver jobs are executed concurrently.

    Note: If the restart log table name is not fully qualified, it is created under the user’s default (logon) database. Alternately, a working database can be specified using the TD_WORKINGDATABASE attribute. If the TD_WORKINGDATABASE attribute is used, the restart log table name must be fully qualified, even if the restart log table is going to reside in the default (logon) database.

    TD_MAX_INSTANCES

    integer

    Provides the total number of instances (master and slaves). Required when using multiple instances of the same driver in a master-slave environment.

    TD_RESTARTMODE

    integer

    Required only before restarting and must be set to one before performing a restart.

    TD_SYSTEM_OPERATOR

    varchar

    Specifies the type of driver being used (in this case TD_STREAM).

    TD_USER_NAME

    varchar

    Provides the name of the user for the Stream driver logon sessions.

    TD_USER_PASSWORD

    varchar

    Specifies the password associated with the user name.
