Introduction to Queues
VCS uses the following Queues for publishing. Depending upon the access rights, you will be able to view these queues.:
Pool Queues: VCS uses Pool Queues for publishing instead of Publisher Queues. Pool Queue supports simultaneous execution of Queue entries.
WVSPreprocessingPoolQueue: This queue is used to generate the contents, upload the contents to cloud storage, and connect to VCS to submit the jobs.
WVSPostprocessingPoolQueue: This queue is used to create the representations upon completion of job from VCS.
WVSFollowerPoolQueue: This queue performs the pre-processing for all the Follower Jobs when batch mode is enabled. Batch mode is batching of only part PWS files in batches for faster processing of jobs from Windchill.
WVSVCSPollingGetJobsSQ: This queue is used to continuously poll the VCS to seek job status (state, job order, job message, and so on).
