A key part of successfully implementing a DB2® workload management solution is identifying
the work.
There are three approaches to work identification: workloads, work
classes, and data tags.
- Workloads can be used to identify the source of work. You can
identify the source at the connection or transaction level by using
key session attributes, such as the application name or the system
authorization ID that submitted the work, for example.
- A work class enables you to identify work by pinpointing certain
characteristics of the work. You can define a work class to identify
the work of interest, such as statements that only modify data on
the data server, for example (INSERT, UPDATE, or DELETE statements,
for example).
- Data tags are available as table space
and storage group data tags. They enable you to identify work indirectly
by the type of data it accesses during execution. By tagging data
of interest, you can identify the work that is accessing that data.
