Field
| Description
|
---|---|
Connection name
| Source connection that you want to archive from. This field is mandatory.
|
Analyze Interim
| Oracle sources only. Determines when the interim table is analyzed for table structure and data insertion.
Default is After Insert and Update. To optimize performance for best results, use the default value.
|
Delete Commit Interval
| Number of rows per thread that the archive job deletes before the job issues a commit to the database.
Default is 30,000. Performance is typically optimized within the range of 10,000 to 30,000. Performance may be impacted if you change the default value. The value you configure depends on several variables such as the number of rows to delete and the table sizes.
Use the following rules and guidelines when you configure the commit interval:
|
Insert Commit Interval
| Number of database insert transactions after which a commit point should be created. Commit interval is applicable when the archive job uses JDBC for data movement.
If your source data contains the Decfloat data type, set the value to 1.
|
Delete Degree of Parallelism
| Number of concurrent threads that are available for parallel deletion. The number of rows to delete for each table is equally distributed across the threads.
Default is 1.
|
Insert Degree of Parallelism
| The number of concurrent threads for parallel insertions.
When the Oracle Degree of Parallelism for Insert is set to more than ‘1’, the java parallel insert of tables is not used.
|
Update Degree of Parallelism
| The number of concurrent threads for parallel updates.
|
Reference Data Store Connection
| Required when you use the history database as the source and you only want to purge from the history database.
Connection that contains the original source reference data for the records that you archived to the history database. The source includes reference data that may not exist in the history database. The archive job may need to access the reference data when the job purges from the history database.
