SSI contexts

One of the most powerful features of windows mode is its ability to combine data from multiple targets in one view in single system image (SSI) mode.

Even the data from Db2 subsystems operating on different z/OS images can be brought together.

The default SSI context of ALL is always available and is the one that is set if you enter windows mode from the Db2 Primary Option Menu. There might be other SSI contexts already defined that group several similar Db2s together, such as PROD or TEST, or a data sharing group.

As you navigate between 

 views, it is often necessary to set another context to look at a different group of Db2s or at a single Db2. You might want to switch out of SSI mode to analyze one Db2 target, or remain in SSI mode but temporarily narrow the focus. This focus is called SCOPE.

The Db2 easy menus have utility options to set context. From EZDSSI, you can hyperlink to view a list of defined contexts and select one to reset the context. From EZDB2, you can hyperlink to view a list of target Db2s and select one to reset the context to a new target. From EZDBA, you can hyperlink and reset either the target or SSI context.

You can also use product-defined dynamic contexts to group data sharing member targets by their data sharing group name. The product address space (PAS) defines these contexts internally for active data sharing targets. The contexts are maintained for the life of the associated coordinating address space (CAS).

To use these contexts, specify CONtext DSG:dsgroup, where dsgroup is the data sharing group name.
