Passport Advantage (PA, PPA): An external IBM website from which installation packages of all IBM products for the version, release, and modification type of releases can be downloaded.
password based encryption key (PBE key): A key that encrypts the value of sensitive properties that are stored in a Global Mailbox database.
payload: An actual business document or file. The payload is not directly stored in a mailbox but referenced to via a message.
PBE key: See password based encryption key.
perimeter server: Communication management software that can be installed in a DMZ and manages communication flows between a perimeter network and Sterling B2B Integrator TCP-based transport adapters.
port number: In Internet communications, the identifier for a logical connector between an application entity and the transport service.
PPA: See Passport Advantage.
producer: A partner who creates and sends files.
producer mailbox path: A configuration within a routing channel template that specifies the path to a mailbox that is monitored by Sterling File Gateway.
protocol: A set of rules controlling the communication and transfer of data between two or more devices or systems in a communication network.
purge: The process by which old data is removed from the system database. Purges minimize the number of unused database records to increase search efficiency and reduce the size of the required physical disk.

Q

queue-based event processing: The process of an event, which is governed by an event rule, being generated and put into the messaging queue whenever a message is added to a Global Mailbox.
queue manager: A component of a message queuing system that provides queuing services to applications.

R

REST: See Representational State Transfer.
rolling upgrade: In clustered systems, updating the system software on a cluster without interrupting service to the users of the cluster.
routing channel: A channel configuration that matches incoming producer files with consumers, transforms the files according to the format specified in the consumer file structure, and sends them to the correct consumer.
routing channel template (RCT): A template that defines the structure through which routing occurs. The RCT specifies producer and consumer mailbox structures and file structures. It mandates which partners can participate in various file transfer scenarios and which file formats they must use. An RCT is required to create a routing channel, which establishes the producer-consumer relationship for file transfers.

single data center processing: Processing that occurs independently within one data center so that files can continue processing during a data center outage.
split-brain: An error state in which the data in one part of a highly available clustered application or system is inconsistent with another due to a network partition or failure, and results in two sets of conflicting data.
static routing channel: A routing channel that identifies the consumer when the routing channel is created.
