When a command runs in the foreground (synchronous command execution), you are unable to issue any other commands until the process completes. When a command runs in the background (asynchronous command execution), you can issue other commands while the process completes.
Most commands run in the foreground, but others generate background processes. In some cases, you can specify that a process run in the foreground. Tivoli® Storage Manager issues messages that provide information about the start and end of processes. In addition, you can request information about active background processes. If you know the process ID number, you can use the number to limit the search. However, if you do not know the process ID, you can display information about all background processes by issuing the QUERY PROCESS command.
Figure 1 shows a server background process report after a DELETE FILESPACE command was issued. The report displays a process ID number, a description, and a completion status for each background process.
