Show volume paths used by active flows
When editing the Volume list, the Show volume paths used by active flows can be used to list
all volume paths currently in use by active flows at the end of the list. By default this checkbox
is turned on. Its state is remembered between uses of the property editor and across Switch
sessions. If the volume path contains a user name, this will be entered in the User name field.
The password is NOT added automatically.
When turning the option off, all volume paths with an empty user name will be removed from
the list.
13.3 Unique name prefixes
Internal job tickets
A key feature of Switch is its ability to remember information about a job (file or job folder) while
it is being processed through a flow. This information is stored in an internal job ticket managed
by Switch.
The internal job ticket for each job contains housekeeping information (such as where the job
was last located) in addition to information about the job's origin and routing.
For example, a job's hierarchy info and email info (attached by specific tools) are stored in its
internal job ticket.
Switch needs a way to associate a particular internal job ticket with its corresponding job, and
vice versa. To maximize flexibility and transparency for the user, Switch uses the filename as the
basis for this mechanism rather than hiding jobs in some database. However Switch may be
handed two or more jobs with the same name (in different input folders, or even in the same
input folder after the first job was moved along).
Thus Switch employs a "trick" to keep similarly named jobs apart: unique name prefixes.
Unique name prefixes
A job is associated with its internal job ticket by prefixing the file or folder name with a unique
identifier that consists of five letters or digits preceded and followed by an underscore.
For example: “myjob.txt” may become “_0G63D_myjob.txt”.
Note that the files inside a job folder are not renamed; only the job folder name receives the
unique name prefix. When a job folder is disassembled into separate files, each of the files of
course receives its own unique name prefix.
For the technically-minded: each of the five characters in the unique name prefix can be a digit
(0-9) or an uppercase letter (A-Z). This allows 36**5 or about 60 million combinations. A different
unique name prefix can be generated every second for about 23 months.
Switch generates a new unique name prefix (and a corresponding internal job ticket) when:
• It detects a job in a folder or in a submit hierarchy.
• It makes a copy of a job.
• A producer (such as email receive) injects a new job in the flow.
• A processor produces a secondary output job that is injected in the flow.
