DARSTRAN

Replicate your Data in an RDBMS and/or The Cloud and keep it Instantly Synchronized

The Innovative Evolution of The Industry-Leading CA IDMS® Replication Toolset

Features

  • No CA IDMS database access is performed except to extract the CA IDMS data for Initial Load of the target RDBMS
  • The core DARSTRAN Replication Engine© and Journal Image Processor© have been designed and written to run on a full range of popular target platforms, including the mainframe. Common code for all platforms ensures high performance, reliability and identical replication on all platforms
  • The core DARSTRAN Replication Engine© and Journal Image Processor© provide superior performance and reliabilty when capturing updates from the Active CV Journals. Updates are processed at COMMIT and/or FINISH and sent to the target platform using the guaranteed delivery provided by IBM's MQSeries®
  • Unlike some other replication tools, No application or CA IDMS® system modifications such as HOOKs, EXITs or DBPROCs are used that could seriously impact and/or destabilize your CVs
  • The innovative design allows ISP to offer optional components to CA IDMS® Network and CA IDMS/SQL® database users who require data replication to DB2 or CA IDMS/SQL on z/OS; DB2, DB2UDB, MS SQLServer, MySQL, Oracle, and Sybase on Windows 2000/2003/2008 Server®, and/or on AIX®/Unix/Linux based and/or on zLinux platforms where the respective RDBMS is supported. Both 32 bit and 64 bit are available as required
  • The user may optionally generate XML to process the replicated data with a variety of third party software products
  • There is no requirement to copy the client's database files for processing off site. All CA IDMS data processing is performed at the client's site under the client's scrutiny and security control
  • The CA IDMS Metadata can be extracted and loaded into your RDBMS of choice for use with various Reporting, Analysis and Drawing Tools. With our Active Journal feature, the RDBMS TABLEs will be kept in sync with the CA IDMS IDD
  • Mutiple targets and Clouds can be synchronized from a single DARSTRAN instance

Components

DARSWIN©
  • Transforms CA IDMS® Schema syntax to RDBMS DDL
  • Addresses CA IDMS® Schema changes that affect an already-configured DARSTRAN©
  • Eliminates the manual updating of replication definitions after CA IDMS® Schema changes
  • Accepts updated Schema syntax, compares it to the original, reports on the differences and automatically incorporates the changes into the replication definition
DARSTRAN©
  • Provides complete data formatting on the mainframe or target platforms
  • Reassembles and transforms Initial Load CA IDMS® extract data and CA IDMS® Journal images into either Fast Load syntax, SQL statements or XML
DARSLOAD©
  • Implemented as a Service for Windows NT® and as a Daemon for AIX®/Unix/Linux to eliminate the need for scripting on the target platform
  • Invokes DARSTRAN© to perform the required data transformations and manages the application of the data to the target RDBMS
  • Configurable to facilitate multiple simultaneous Initial Data Loads to greatly reduce target RDBMS run times
  • Incorporates ERROR logging facilities

Benefits

Cost Savings & Performance
  • DARSTRAN© reduces the impact on mainframe resources through highly optimized code and, optionally, by moving the Archive Journal processing to the target platform
  • Near Real-Time target updates are achieved using the sophisticated Active Journal facility in conjunction with the speed, reliability and guaranteed message delivery of IBM'S MQSeries© software running on the mainframe and target platforms
  • Replicate to an RDBMS and/or the Cloud in the same DARSTRAN instance
  • Sysplex aware
  • Dramatic performance improvements may be realized if the parallel processing features of DARSLOAD© are fully exploited in installations where the available CPU cycles on the target platform exceed those available on the mainframe

Note: Journal processing requiring decompression using CA PRESSPACK® is only supported on the mainframe. This is a limitation of the CA-PRESSPACK® code and not DARSTRAN®

Resolution of SET OWNER Relationships
  • Built-in logic dynamically computes OWNER pointer values for a SET where OWNER pointers are not defined in CA IDMS® by using the SET’s NEXT pointer within the replica. Absolutely NO access to the CA IDMS® application database is required to formulate the relationship
  • Predictable response times plus elimination of “dirty reads” of the CA IDMS® application database result in substantial performance benefits
Comprehensive Error Logging
  • Extensive Error logging facilities
  • Formatted for loading into an RDBMS table for query and analysis
  • Includes logging of invalid Dates and Elements that contain data that does not match the defined Data Type
  • Flexible error detection provides logging of information at the Schema, Record, or Element level
