Management Information Base Object Identifiers
A Management Information Base (MIB) is a database of Object Identifiers (OIDs) that can be
used to monitor device objects using SNMP. An MIB OID can point be a printer tray, cartridge or
hard disk, or to modem mode. Using an SNMP condition, PlanetPress Workflow can
communicate with a device located at a given IP address and request the status of the object
identified by a given MIB OID number. Object Identifiers are typically assigned and registered
by device manufacturers. They are based on a standard known as Abstract Syntax Notation
One (often referred to as the ASN.1 standard).
On Error Tab
The On Error tab is common to all tasks. Details can be found in the" Task Properties Dialog"
on page777.
By default, any action task, branch, splitter or condition that generates an error will simply be
ignored, and the task just under it (not within a branch)will be given control of the job file
without any modification. Any initial input task that generates an error will stop the process from
running as a whole, and output tasks will not generate output. The On Error tab can be used to
overwrite the default behaviors.
