R/HSTLSTAC "Accounting by Connection History List" includes many wait buckets, but it is massing a column for Not Accounted time (IQL var UNACC-DB2-TIME)
It includes a Wt Others which initially was though to be UNACC-DB2-TIME, but found that it means the following:
This field shows wait time statistics for class 3 not included in previous fields.
The field includes wait times such as wait time caused by suspension for
sending messages to data sharing group members, wait time for TCP/IP LOB and
XML materialization, wait time for asynchronous IXLCACHE/IXLFCOMP invocations,
wait time for force-at-commit, wait time for autonomous transactions to
complete, and others.
The value is aggregated for one or all connection types.
It includes the fields listed below.
IQL Name: DECL-WAIT-OTHERS
