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

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, reliablility and identical replication on all platforms.
  
  
•   The core DARSTRAN Replication Engine^© and Journal Image Processor^© provide superior performance and reliablilty 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^®. No application or CA-IDMS^® system modifications are required.
  
  
•   The innovative design allows ISP to offer optional components to CA-IDMS^® users who require data replication to an RDBMS on mainframe, Windows NT^® and/or AIX^®/Unix/Linux based platforms.
  
  
•   The user may optionally generate XML to process the replicated data with a variety of third party software products or generate data in a format suitable to the Ab Initio software.
  
  
•   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.
  
  Components
  
  DARSWIN ©
•   Transforms CA-IDMS^® Schema syntax to RDBMS DDL or proprietary Ab Initio software syntax.
  
  
•   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 or Ab Initio software.
  
  
•   Configurable to facilitate multiple simultaneous Initial Data Loads to greatly reduce target RDBMS run times.
  
  
•   Incorporates ERROR logging facilities.
  
  
•   Will support SNMP (Simple Network Management Protocol) in the near future as an interface to monitoring the DARSTRAN^© software with tools such as CA-Unicenter^® and HP-Openview^®
  
  BENEFITS
  
  COST SAVINGS AND 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.
  
  
•   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 which requires invoking the CA-PRESSPACK^® software 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.
