Understanding Managing Pub/Sub Domains
PeopleSoft Integration Broker includes a set of Oracle Tuxedo servers that monitor database tables and process items in the tables. The processing can include running PeopleCode programs, creating publication and subscription contracts, and so forth.
The Domain Status page enables you to view the domains that have pub/sub servers on them that are running against the application database. You can also use this page to manually set domain grace periods to allow processing in a domain to finish before you pause the processing or take the domain offline.
In addition, if a machine with a domain on it crashes, the integration system may still operate as if the processes in the domain are still working on items in the runtime tables. The Domain Status page enables you to set the domains to inactive so that other pub/sub servers can complete the processing of these items. This enables you to recover from domain and machine crashes.
