We have found and corrected a major cause of performance problems within z/XDC. The degradation would occur when using the FORMAT command (or WHERE command) to display a mapped control block or data area using z/XDC’s internal disassembler. This occurred:
– When the map was built from SYM data,
– Or was built from ADATA *AND* the OBJECT operand was used on the FORMAT, WHERE or SET FORMAT commands.
The fix for this issue was published as FHC-1901A.
