Trace activation

To fully exploit OMEGAMON® XE for Db2 PE's realtime performance monitoring abilities, Accounting trace class 1 and class 2 must be active while OMEGAMON XE for Db2 PE is monitoring your DB2 system. If these traces are not active, specific data elements (listed in Table 1) will not be available to OMEGAMON XE for DB2 PE. Also, some data related to reusable threads becomes cumulative, instead of reflecting a single transaction (see Table 1).

To use the near-term history reporting facilities, you must activate some traces as well. Unlike the realtime portion of OMEGAMON XE for DB2 PE, near-term history reporting depends entirely on data supplied by traces. To determine exactly which traces you must activate to report on specific data elements, see the online data dictionary.
