The "Create Job Queue (CRTJOBQ)" command can be used at any OS/400 command line to create a job queue. This queue needs to be attached to a subsystem using the "Add Job Queue Entry (ADDJOBQE)" command. A unique "Sequence number" must be assigned for each job queue attached to the subsystem. You also define the "Maximum active jobs" on this command. If set to "1", the job queue is single-threaded - only one job runs at a time. If set to "5", up to 5 jobs would run simultaneously through this job queue. If more than 5 are submitted to the job queue at one time, the remainder would wait in the job queue until a slot freed up. Setting this value to *NOMAX means that all jobs submitted to this job queue would immediately go active. No jobs would ever queue up and all jobs would run simultaneously.
