CONNECT

You can use the QMF CONNECT command to connect to a different system within your distributed network, with remote unit of work, during a QMF session. You can also use the QMF CONNECT command to access remote databases supported by QMF. When you connect to the remote system, this system becomes the current location.When you write applications, you can issue this command from:

• The callable interface
• The command interface
• Within a procedure (linear or with logic)

Certain aspects of your applications can be affected when you use the QMF CONNECT command to start remote unit of work. Be aware of the following considerations:

• When your application connects to a new location, the QMF profile, command synonyms, and function keys are reinitialized to the values at the new (current) location.
• All callable interface and command interface programs that start QMF and issue QMF commands must reside on the same system as the user (the local system). After the program starts QMF at the local system, the program can issue a QMF CONNECT command to connect to a remote database. Any subsequent QMF commands or SQL statements that affect database objects are run at the current location (the remote database).
• All programs started by QMF must follow the conventions of the operating system on which QMF is running (the local system).
• Different types of commands behave differently with remote unit of work. When your applications use remote unit of work, be aware that all system-specific and most QMF commands run at the system where QMF is running (usually, your local system). However, when a QMF command does either of the following:
  • Sends SQL commands to the database
  • Uses or alters QMF objects and data stored in the database

  These commands affect the database at the current location.
