START command

Use the START command to start started tasks, which support system functions such as IMS™, CICS®, and RACF®. Started tasks are defined in cataloged procedures (residing in procedure libraries) or through jobs residing in a partitioned data set defined in master JCL.

Note: In general, IBM® recommends that when you start a subsystem, you make the subsystem name specified in the IEFSSNxx parmlib member the same as that of the member you use from SYS1.PROCLIB. If the names do not match, you may receive error messages when you start the subsystem.

The following figure lists the tasks the START command can perform. Use it as an index to details about particular uses of the command.
