Jobs are distributed over the available ITP/Document Processors in the order they arrive. If a single ITP/Server installation is used to serve both ITP/OnLine and batch jobs, long-running batch jobs may cause a delay in the processing of the interactive ITP/OnLine requests. To prevent this, ITP/Server offers two options that cause ITP/OnLine jobs to be run before other jobs, if possible. Add one or both of these to the dp.ini file in the folder Config of the folder ITPWork, and restart ITP/Server:
[Configuration]
PrioritizeOnLine=Y ; Y or N, default value N
DedicatedOnLine=<number> ; Number of ITP/Document Processors to
; reserve, default value 0
PrioritizeOnLine will, if set to Y, cause ITP/Server to schedule ITP/OnLine jobs ahead of other jobs, if taking jobs from the queue. Note that this will only have an effect if both ITP/OnLine jobs and other jobs are queued. If all ITP/Document Processors are processing jobs and a ITP/OnLine job is submitted, it will have to wait until an ITP/Document Processor has finished processing its job.
With DedicatedOnLine you can reserve one or more ITP/Document Processors for ITP/OnLine jobs. These ITP/Document Processors will not be used for other, possibly long-running, jobs. This makes it much more likely that an ITP/Document Processor will be available quickly for processing an ITP/OnLine job, if one is submitted.
Note
These options are now available on the tab Advanced in the ITP/Server Administrator.
