ConfigID
EWLM V1R1– OS/400 identified the user data for an EWLM instance via configID– All other platforms identified the user data by providing path to working
directory
EWLM V2R1– All platforms use configID to identify the user data for an EWLM
instance– The configID identifies a subdirectory within the
EWLM_DATA_ROOT/servers directory. – EWLM_DATA_ROOT is selected during install. Default value is
provided specific to OS platform which user can modify.

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios
