Parallel Processing Support in CA IDMS/DB
CA IDMS DLI Transparency supports DL/I parallel processing in two ways:
- Multiple PCBs ── A CA IDMS/DB subschema can include definitions to reflect any number of PCBs in a corresponding PSB, with no limitation on the DL/I structures contained in the PCBs. For example, when two PCBs that define the same hierarchy are both used by a DL/I application, CA IDMS DLI Transparency will maintain database positioning (currency) independently for each PCB.
- Multiple positioning ── The DL/I PCB statement allows you to optionally specify separate positioning for each hierarchical path in a database definition. CA IDMS DLI Transparency will maintain separate currency for each CA IDMS/DB structure that corresponds to one of the DL/I hierarchies.
