The "Submit Background Job" screen requests background jobs. A background job is a program that is processed centrally, without a logged-on user. Background jobs serve repetitive or time-consuming processes. The number of background jobs that run simultaneously is limited. See also [[Invantive Estate/Subjects/Advanced/Background Jobs|Background Jobs]], [[Invantive Estate/Subjects/Advanced/Background Scripts|Background Scripts]] and [[Invantive Estate/Subjects/Advanced/Background Schedulers|Background Schedulers]]. The entry fields have the following meaning: - "Script": The background script that is requested. - "Requested Start Time": The first possible point in time at which the background job may be executed. A second screen opens together with this screen when the script needs parameters. For example, a script can ask for an old prefix schema and a new prefix schema. The entry fields of that second screen have the following meaning: - "Old prefix schema": The prefix of the old schema. - "New prefix schema": The prefix of the new schema.
