Running DB2 guest sharing

You have the option to connect your CICS partition to a DB2 database on either VSE or VM. When VSE is a guest to VM and shares data with the host's applications through a common VM DB2 database, it is called guest sharing. The benefit of SQL guest sharing is that both VM and VSE users can use a common database. QMF requires minimum levels of VM/ESA Version 1.1 and DB2 Version 6 to use QMF in an SQL guest sharing environment. You do not have to install QMF for VM.

If you establish an SQL guest sharing environment and want to install QMF on VSE, complete the installation as if VSE owned the database. The VM DB2 database is transparent to the VSE user.

However, if you have both DB2 and QMF installed under VM/ESA, and you want to install an additional QMF product in VSE, you can skip the part of the QMF installation that deals with database installation. During the install process, you are told when to skip that step. Otherwise, the remainder of this manual assumes that you are installing QMF into a DB2 for VSE database.
