Source System

Configure the Manager process and primary Extract on the source system.

To Configure the Manager Process

1. On the source, configure the Manager process.

2. In the Manager parameter file, use the PURGEOLDEXTRACTS parameter to control the purging of files from the local trail.

To Configure the Primary Extract

1. On the source, use the ADD EXTRACT command to create an Extract group. For documentation purposes, this group is called ext.

   ADD EXTRACT ext, {TRANLOG | INTEGRATED TRANLOG}, BEGIN time [option[, ...]]

   See Parameters and Functions Reference for Oracle GoldenGate for detailed information about these and other ADD EXTRACT options that may be required for your installation.

2. On the source, use the ADD EXTTRAIL command to create a local trail.

   ADD EXTTRAIL local_trail, EXTRACT ext

   Use the EXTRACT argument to link this trail to the primary Extract group. The primary Extract group writes to this trail, and the data pump groups read it

3. On the source, use the EDIT PARAMS command to create a parameter file for the primary Extract group. Include the following parameters plus any others that apply to your database environment. For possible additional required parameters, see the Oracle GoldenGate installation and setup guide for your database.

   -- Identify the Extract group:
   EXTRACT ext
   -- Specify database login information as needed for the database:
   [SOURCEDB dsn_1][, USERIDALIAS alias]
   -- Log all scheduling columns if using integrated Replicat
   LOGALLSUPCOLS
   -- Specify the local trail that this Extract writes to
   -- and encryption algorithm:
   ENCRYPTTRAIL algorithm
   EXTTRAIL local_trail
   -- Specify tables and sequences to be captured:
   SEQUENCE [container.|catalog.]owner.sequence;
   TABLE [container.|catalog.]owner.table;
   

Use EXTTRAIL to specify the local trail.

To Configure the Data Pump Extract Groups

1. On the source, use the ADD EXTRACT command to create a data pump for each target system. For documentation purposes, these groups are called pump_1 and pump_2.

   ADD EXTRACT pump_1, EXTTRAILSOURCE local_trail, BEGIN time
   ADD EXTRACT pump_2, EXTTRAILSOURCE local_trail, BEGIN time
   

   Use EXTTRAILSOURCE as the data source option, and supply the name of the local trail.

2. On the source, use the ADD RMTTRAIL command to specify a remote trail that will be created on each of the target systems.

   ADD RMTTRAIL remote_trail_1, EXTRACT pump_1
   ADD RMTTRAIL remote_trail_2, EXTRACT pump_2
   

   Use the EXTRACT argument to link each remote trail to a different data pump group. The linked data pump writes to this trail.

   See Parameters and Functions Reference for Oracle GoldenGate for additional ADD RMTTRAIL options.

3. On the source, use the EDIT PARAMS command to create a parameter file for each of the data pumps. Include the following parameters plus any others that apply to your database environment.

   Parameter file for pump_1:

   -- Identify the data pump group:
   EXTRACT pump_1
   -- Specify database login information:
   [SOURCEDB dsn_1][, USERIDALIAS alias]
   -- Decrypt the data only if the data pump must process it.
   -- DECRYPTTRAIL
   -- Specify the name or IP address of the first target system
   -- and optional encryption of data over TCP/IP:
   RMTHOSTOPTIONS target_1, MGRPORT port_number, ENCRYPT encryption_options
   -- Specify remote trail and encryption algorithm on first target system:
   ENCRYPTTRAIL algorithm
   RMTTRAIL remote_trail_1
   -- Specify tables and sequences to be captured:
   SEQUENCE [container.|catalog.]owner.sequence;
   TABLE [container.|catalog.]owner.table;
   

   Parameter file for pump_2:

   -- Identify the data pump group:
   EXTRACT pump_2
   -- Specify database login information as needed for the database:
   [SOURCEDB dsn_1][, USERIDALIAS alias]
   -- Decrypt the data only if the data pump must process it.
   -- DECRYPTTRAIL
   -- Specify the name or IP address of the second target system
   -- and optional encryption of data over TCP/IP:
   RMTHOSTOPTIONS target_2, MGRPORT port_number, ENCRYPT encryption_options
   -- Specify remote trail and encryption algorithm on second target system:
   ENCRYPTTRAIL algorithm
   RMTTRAIL remote_trail_2
   -- Specify tables and sequences to be captured:
   SEQUENCE [container.|catalog.]owner.sequence;
   TABLE [container.|catalog.]owner.table;
