tcVISION and VSAM

tcVISION supports VSAM files as source and target, directly or under CICS control. Data changes are captured and propagated automatically. There are several methods for the capturing and processing of change data. These processing methods can be flexibly adjusted to the customer's requirements, and can be quickly implemented into a production environment.

 

These methods are:

  • Capturing change data information in real-time
  • Processing of CICS journals
  • Capturing data changes using an intelligent batch compare program
  • BULK transfer of entire VSAM files
  • Direct apply of changes from other systems (e.g. Oracle, Db2 LUW, SQL Server, IMS, Adabas, etc.)

 

The detected changes are propagated to the target system directly or are provided to it in the desired format. Due to a modular design, the data transfer process can be distributed across several platforms for optimal workload balancing. There are additional tools to adjust the data for the target system using the customer's logic during the transfer.

 

Special Features

  • Capturing change data information in real-time for CICS (z/OS and z/VSE)
  • Capturing the data changes in real-time for VSAM batch (z/VSE)
  • Processing of CICS journals
  • Usage of VSAM files as source and target of a replication (Batch and CICS)
  • Transactional processing on base of LUWs
  • Integrated methods for bidirectional synchronizations
  • Automatic detection of metadata from existing COPY structures:
    • Support of COBOL, PL/I, ASSEMBLER, CPG, RPG
  • Different record types and record structures are supported.
  • Processing of "virtual tables" for record structures that are based on OCCURS and OCCURS DEPENDING ON
  • Integration of VSAM data with other resources (mainframe or open systems) during the data transfer using lookups and joins
