Publishing jobs can sometimes fail, or have unexpected results. For example:
- Content is marked as not published, even though it is.
- Publish doesn't stop (preventing a publish).
- Publish job is interrupted.
Why didn't my Publish run?
There are a few reasons why a publish job could fail:
- The user has been set up with a Regular User account, and therefore, does not have permission to publish. Check the user account to confirm.
- Another Publish job was already running when the new job tried to begin. Check the job logs to confirm.
- The user scheduled the job to run at a time they did not intend. Check the job schedule to confirm
- The job queue is full on the servers.
Why can't I submit a publish job? The option is unavailable.
I'm trying to stop a job, but it doesn't appear to be actually stopping. Why?
Jobs, such as publishes, server directory uploads, and so on, operate as independent threads running on the server. The UI does not have direct access to these processes. Instead, it submits a stop request to the thread. So, when the thread gets to a point in its processing loop where it checks for the request, it terminates. How long it takes for a process to get to one of those checkpoints depends on the type of job running. It also depends on the specifics of that instance of the job.
The "Stop" functionality sets a "JOB_STATE_STOPPING" for the job that will interrupt the job the next time that application looks at the state. The timing is dependent on how often and when the process checks the state.
The IR and IS publishes have four points that the state is checked:
- Near the start, when Scene7 is looking at the servers for what type of files it must process, and whether a manifest is required.
- After the manifest is created, as Scene7 flips to a new publish server.
- During login to the publish server to deliver the files (there can multiple logins by server).
- Before sending catalogs.
In addition the IS Publish checks periodically during main manifest creation for interrupts.
With IR publishes with Vignette Format, much of the time of the publish is creating the derived output vignettes for the formats. There is no check of interrupts in this area. It is hard to knock a job down for some time if there are many to produce for the job.
Video Publishes has two points that are checked:
- Near the start, when Scene7 is looking at the servers for what type of files to process, and whether a manifest is required.
- During login to the publish server to deliver the files
The Upload from Server Directory job (Upload via FTP) has various points that it checks to the job stop state during the traversal of the folder tree. However, if the client has a flattened folder with no subfolders, it could never stop processing once we have the list of files from the folder to upload.
