c-treeRTG V2 Update Guide

Tighter Integration with Your COBOL Applications

c-treeRTG V2 tightly integrates with your COBOL application for the best performance and data integrity ever.

This release of c-treeRTG implements many enhancements aimed at seamlessly integrating with your COBOL application. The list of new and improved features in c-treeRTG V2 goes on and on. Here is a brief summary:

• Improved updates during scans on duplicate index

  When c-treeRTG scans a file with an index that allows duplicates, a record that was changed without updating the key used for scanning is now updated only once.

• File organization specification allows you to fine-tune COBOL integration

  A new <file> configuration attribute makes it possible to specify the file organization, such as indexed file, relative file, line sequential file, record sequential file, etc.

• File locking behavior conforms to ACUCOBOL's locking

  Integration with ACUCOBOL is fine-tuned like a Swiss watch. The <runitlockdetect> setting now enforces record locks as well as file locks so it is possible, for example, to exclusively open a file twice from the same run unit.

• Better handling of index re-organization errors due to redefined schema

  Improvements in V2 better handle the situation when a directive redefines the schema and there is no valid combination of fields to compose a key.
