During Adabas migrations, there is a need to process existing PLOG tapes created by the old version of Adabas and process PLOG tapes created by the new version of Adabas. The CA PLEU GLOBALS parameter ADAVER indicates which version of Adabas created the PLOG tapes so data can be extracted correctly.
CA PLEU V4.1 supports data extraction from both Adabas V7.1 and V7.4 PLOG tapes. ADAVER defaults to 71 if the ADAVER GLOBALS parameter is omitted, therefore, to process Adabas V7.4 PLOG tapes, the ADAVER parameter must be added or modified to indicate a 74 PLOG tape is being input:
