IBM Db2 LUW Agent for Gluesync: Key Features
Core principles
This agent establishes a connection to the IBM Db2 for LUW via a built-in JDBC driver.
Change data capture
Gluesync on IBM Db2 for LUW uses the GDC (Gluesync Data Capture) feature to let the magic happen under the hood, more specifically Gluesync adopts an optimized triggers structure to catch events generated by operations that hit fields in your source DB2 LUW database.
Triggers on GDC are based on a per-transaction logic and only track changed row IDs, storing data on a table called Action logs
table where all changed row IDs are stored and their data type is maintained unaltered.
This technique is also known as change tracking pattern. This is the opposite of change data capture which does not require a copy of all the data present in all the columns involved in a commit, this ensures performance gain and less footprint per transaction on your source database since no data transformation or manipulation is being required by our design.
Supported version
With this agent, you can target any version of IBM Db2 for LUW starting from 11.5.
Q&A
I have got DB2 on an i series system, is it supported? IBM Power (AS/400) is supported and requires the usage of a specific Gluesync source connector for IBM Power that makes use of the AS400 built-in journal. To read more about this specific source connector you can follow this link.
I have got DB2 running on z/OS (aka mainframe) is it supported? This specific version has not yet been tested. If you would like to consider helping us with testing in this system please reach out to us by writing at hello@molo17.com.
