Treehouse Proof of Concept: Bi-directional Replication Between Adabas and SQL Server

Chris Rudolph and Kevin Heimbaugh, Senior Technical Representatives for Treehouse Software, visited a customer site (a large retail and distribution company) to perform a five-day proof of concept (POC) of tcVISION with bi-directional replication between Software AG’s Adabas and Microsoft SQL Server.

Chris and Kevin initially met with the customer team, consisting of the DBA, Applications Manager, and a technical applications person. The agenda for the week was set to:

  • Import metadata from several Adabas files
  • Bulk load the Adabas data into SQL Server
  • Set up replication from Adabas to SQL Server
  • Add the bi-directional replication back to Adabas

Additionally, there were a few other items the customer wanted the Treehouse team to address, including support for date formats; timestamps for bi-directional replication to avoid update conflicts; using Predict views to define multiple SQL Server tables; and support for MUs and PEs. Chris noted that everything on the customer’s list is easily supported, and there are several options for the update scenarios that can be used.

After the tcVISION components were installed, the POC began by using tcVISION’s Control Board to define a metadata repository database in SQL Server. Once that was set, the teams moved on to import the first Adabas file’s metadata using tcVISON’s Metadata Import Wizard. As part of this process tcVISION generated Adabas to SQL Server schemas and field-to-column links as well as created target tables in SQL Server. Bulk Transfer scripts were created using a wizard to read the Adabas file on the mainframe, and load the data into SQL Server using the SQL Server bulk loader. Chris created a control script to show how tcVISION can concurrently bulk transfer multiple Adabas files into SQL Server This required increasing the tcVISION Manager’s VSE partition size to successfully test multiple load scripts executing in parallel.

The teams moved on to define the real-time change data capture (CDC) scripts necessary to process the Adabas PLOG. The tcVISION scripts use a two-phase approach to queue captured Adabas transaction on the open platform, then transform and apply the transactions to SQL Server. The scripts were set up to automatically generate detailed logs to track the PLOG transactions captured, SQL statements successfully applied to SQL Server, failed SQL statements, and informational items such as auto-corrected data and transactions rejected due to processing rules.

Now that several tables were defined and loaded, the bi-directional process was set up. SQL Server CDC was enabled for each table to be replicated. The team made a change within SQL Server and verified that the change show up in the SQL Server CDC tables. The SQL Server-to-Adabas mappings were defined in the tcVISION metadata repository, including the “back update check” to ensure only non-tcVISION transactions are captured, and the scripts on both Windows and mainframe were defined to create the LUWs from the SQL Server CDC and apply the changes to Adabas.

CDC from SQL Server to Adabas was successfully tested. Chris then showed the ability to create Journal replication where each change can be captured by replication type. The team spent time creating a few more mappings so multiple file / table updates could be tested, in addition to doing updates while the scripts were stopped to simulate a lost connection. This included setting up a new script to process copied PLOG datasets created by the ADARES utility.

The team defined the remainder of their Adabas files to the metadata repository. Some were set them up for bi-directional replication, and others were setup for unidirectional replication and Journal replication. Everything work as expected at the wrap-up meeting where the team provided a live demonstration to management of tcVISION and the items accomplished. The final tcVISION presentation and demo went very well, and everyone was pleased with the progress made during the week.

TREETIP: Integrate Mainframe Data Sources In Your Big Data Initiatives

tcVISION supports a vast array of integration scenarios throughout the enterprise, providing easy and fast data migration for mainframe application modernization projects and enabling bi-directional data replication between mainframe, Linux, Unix and Windows platforms. This innovative technology offers comprehensive abilities to identify and capture changes occurring in mainframe and relational databases, then publish the required information to an impressive variety of targets, both on-premise and Cloud-based.

Analysts have observed that perhaps 80 percent of the world’s corporate data still resides on mainframes. So it’s no surprise that Bloor Research (http://www.bloorresearch.com/research/spotlight/big-data-and-the-mainframe/), notes that “it is necessary today to place the mainframe as a ‘first-class player’ in any enterprise Big Data strategy.”

In February 2017 we highlighted tcVISION’s support for replication to the leading NoSQL database MongoDB. MongoDB continues to increase in popularity as a back end for operational applications with real-time requirements.

tcVISION also supports analytics and “mainframe offload” Big Data use cases that generally leverage Hadoop HDFS and/or streaming data transport. With tcVISION, data from a wide variety of IBM mainframe data source can be quickly and easily replicated to Big Data targets, requiring minimal mainframe know-how and having minimal impact on the mainframe.

TREETIP: tcVISION Allows for Surprisingly Innovative Uses

tcVISONv6

Treehouse Professional Services consultants help Adabas / Natural customers in a variety of ways, including DBA services, performance tuning, change management implementation and training, and data replication planning and training. Our experience and long history of service to the Adabas / Natural community helps us create innovative solutions for our customers’ challenges.

Recently Treehouse Senior Technical Representative Chris Rudolph assisted a customer with a tricky data replication problem. The customer uses tcVISION to perform bi-directional replication between Adabas and an RDBMS during the phase-in of a new application. Unfortunately, the new application incorrectly updated certain columns in the RDBMS, which were then replicated to Adabas. The customer attempted to address the issue by running a series of ADASEL reports against the Adabas PLOG and manually checking for “bad” transactions, which was a very time consuming process that pulled the Adabas DBA away from her normal duties.

Chris explained that tcVISION could expedite the process by replicating all transactions for the Adabas file to a journal table capturing the “before” and “after” values of the problematic columns. The developers working on the new application could then identify invalid values, correct the application, and patch the data themselves. This also allowed the Adabas DBA to return to their normal duties.

The journal table now includes columns to display the “before” and “after” values of the corrupted column, Adabas transaction time, end transaction time, operation and Adabas userid. The customer’s developers immediately recognized immense value from being able to query the journal table to find bad data, patch the data, prove that corruption is no longer taking place, and verify that all corrupted instances of the data have been patched. Journal tables have been added for all replicated Adabas files, and the developers now rely on the journal tables for all of their data patches.

PRODUCT SPOTLIGHT: tcVISION v6 Overview and Updates

tcVISONv6

Several exciting new features and updates are now in tcVISION v6, including new output targets Adabas LUW, DB2 BLU, EXASOL, Hadoop,and MongoDB. Additionally, new input sources include z/OS VSAM Logstream (CICS and Coupling Facility / Shared VSAM),z/OS VSAM Batch Extension, z/OS DBMS to Logstream, CA IDMS v17, CA Datacom CDC, IMS Active Log and SMF data.

Another feature recently announced is the tcVISION “Direct Loader” for BULK_LOAD processing. The function does not require output to a sequential file, and the loader utility for the target DBMS is called via API with data passed directly. Direct loader supports PostGreSQL, Microsoft SQL Server and DB2 LUW / DB2 BLU. The advantage of using the Direct Loader is the elimination of disk access in writing and reading the sequential loader data file. File output is still supported (e.g., where loader data is to be distributed to other machines).

Finally, as mentioned in a previous Treehouse Blog, with tcVISION v6 comes the newly enhanced web statistics functionality and web server. Any standard web browser can access this server (Internet Explorer, Firefox, Opera, Chrome, Safari, etc.)

This valuable feature enables users to view data from the tcVISION Manager Monitor, and statistical and operational information from the tcVISION Manager network.
