Do Find Without Locks on SDS ports
FDWOL is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.
This parameter specifies that all FINDs done by the Janus Specialty Data Store are to be done as FIND WITHOUT LOCKS. This can minimize the impact of Janus Specialty Data Store applications on 3270 applications and reduce record locking conflicts caused by large Janus Specialty Data Store request. On the other hand, FDWOL could cause severe Model 204 errors especially in reuse record number files. The default for SDS ports is no FDWOL.
Valid only for SDS (also known as OMNI and OAS) ports.
