| This chapter examines NDS/eDirectory's use of obituaries and the major NDS/eDirectory background processes. The following is a summary of the time intervals at which the various processes run: | NDS Background Process | Default Time Interval | | Backlink/DRL | 780 minutes (that is, 13 hours) | | External reference life-span | 192 hours (that is, 8 days) | | Flat Cleaner | 720 minutes | | Heartbeat ”data | 60 minutes | | Heartbeat ”schema | 240 minutes (4 hours) | | Janitor | 2 minutes | | Limber | 3 hours; 5 minutes if processing was unsuccessful | | Server state Up threshold | 30 minutes | | Schema update interval | 60 seconds | | Schema synchronization interval | If processing was successful, schedule to run after next schema heartbeat (which is 4 hours); otherwise , schedule to run after schema update interval plus one second | | Synchronization interval for attributes flagged as Sync Immediate | 10 seconds | | Synchronization interval for attributes flagged as Sync Never | 30 minutes for NetWare 4; 60 minutes for NetWare 5 and higher and eDirectory servers | This chapter also examines several object-related and partitioning replication “ related operations to show how DS actually performs these operations. Understanding how these processes operate lays a foundation for understanding how to effectively troubleshoot and resolve problems. The next two parts of this book examine how to use this information to troubleshoot and resolve issues with NDS/eDirectory, using the different tools available. The following chapters also examine ways to combine tools using different techniques in order to streamline the troubleshooting-resolution process. |
