tcVISION – z/Stream

Why tcVISION z/Stream?

The majority of today's transaction data still resides on mainframes.

The efficient transfer of mainframe data into the new IT world is crucial for the success and future potential of enterprises.

The topicality of information is mandatory for analysis and decision processes. It is the only way an enterprise can react quickly to changes in markets and to new trends.

There are many reasons to transfer data from the mainframe to other databases or storage systems running on UNIX, Linux and MS-Windows or Cloud and Hadoop architectures.

Conventional ETL processes cause high costs for extraction and transformation of data.

For one part they are caused by mainframe CPU load that is required by many ETL solutions for extraction and transformation of data.

These costs are also connected to system and database experts in the mainframe area. This expertise is becoming sparse and more expensive compared to other platforms.

Hadoop based BigData and analytics solutions are cheaper and more powerful.

tcVISION z/Stream does not need to access the original data source in order to transfer mainframe data.

Backup and recovery files already existing in z/OS and z/VSE environments are read in binary format.

tcVISION z/Stream therefore does not need to process definitions on the mainframe or any active connection to the mainframe.




  • tcVISION z/Stream is easily installed in no time.
  • No mainframe knowhow is needed.
  • No installation on the mainframe is needed.
  • It is an alternative to exchange data without mainframe change data capture.
  • tcVISION z/Stream is efficient as it does not need to do any extract processing.
  • tcVISION z/Stream is effective as no active production data is used.
  • Low impact: Already existing copies of production data on the mainframe are used for data exchange.
  • Cheap: Data is transferred and processed in compressed format.
  • Transparent: All data transfers are comprehensible.
  • Independent: No mainframe knowledge needed.


Supported Data Sources

  • Db2 z/OS imagecopy
  • Db2 z/OS archive log files
  • Adabas unload files and PLOG files (z/OS and z/VSE)
  • CA-Datacom unload extract/backup and SPILL files (z/OS and z/VSE)
  • IMS unload and log files (z/OS)
  • SMF/DUMP files (currently only Db2 auditing data z/OS)
  • Sequential and VSAM files (z/OS and z/VSE)

Supported Targets

The following file formats and databases are supported:

  • CSV files on local disk or remote Hadoop HDFS
  • Db2/LUW & BLU
  • Informix
  • MongoDB
  • Oracle
  • Exadata
  • Netezza
  • MS-SQL Server
  • PostgreSQL
  • MySQL
  • MariaDB
  • Splice Machine
  • Exasol
  • Terracotta
  • JMS Queues
  • HDFS / HIVE / HBase
  • Teradata via OBDC
  • Adabas LUW


System Requirements

The current version supports the following systems in 32 and 64-bit:

  • Windows 7, 8, 8.1 and Windows 10
  • Windows Server 2008, 2012, 2014
  • Various Linux distributions
  • Oracle, UNIX, Solaris
  • Linux for System/z



  • Cost reduction and project autonomy since there are no mainframe skills required
  • Resource friendly: Already existing copies of mainframe data are used for the transfer so that the production system is not involved in the data transfer.
  • Cost reduction for data transfer: tcVISION z/Stream reduces data transfer to a minimum. Data is sent in compressed format and de-compressed on the target system.
  • Upgrade to a highly performant real-time data integration solution is possible at any time: For "real-time" synchronization and replication (also on record level), tcVISION z/Stream can be upgraded to tcVISION z/Unlimited.
  • Great topicality: tcVISION z/Stream can perform data transfer processes in parallel, so latencies between source and target are reduced to a minimum.
  • It supports real-time change data capture functionality for nearly all data sources on IBM mainframes and relational databases on open systems.
  • Furthermore tcVISION z/Unlimited contains a flexible solution for transformation and modification of data on record level.
  • tcVISION z/Unlimited provides a complete middleware infrastructure to exchange data between various systems.
  • Data can be exchanged in real-time, event-driven or at defined points in time. Data exchange with tcVISION z/Unlimited requires no additional middleware or message queues.
  • With tcVISION z/Unlimited real-time data exchange is possible in a bidirectional manner.
  • The usage of tcVISION z/Unlimited is ideal in heterogeneous system environments where "near real-time" data topicality must be guaranteed across system borders. This includes parallel operation on different platforms with overlapping transactional data sources, data and system migrations without a "big bang", solutions for application modernization and usage of new IT technologies.
