Overview
This guide provides recommendations for minimum SQL Merge Replication to keep ACM working in case of a fail-over. However, More more can be done using replication. Below is an outline of the core tables to help guide you in setting up your system.
Temporary/Data Tables
The following tables are treated as temporary tables and the data is constantly being shuffled aroundchanging. Table data is either used only for calculation and/or movement that can be regenerated which is re-generated on demand. These tables should NOT be replicated.
- JobSchedules
- ScheduledJobs
- ScheduledJobSteps
- tblArchiveStaging
- tblCommStatsStaging
- tblDailyRecs
- tblDailySummary
- tblHourlyRecs
- tblHourlySummary
- tblGcWritePending
- tblItemStaging
- tblObjectId
- tblPubStaging
Required Data Tables
The next This set of tables are the tables that contain the data that is necessary for starting ACMACM configuration, history collection sequence positions and item persistence. If you want a fail-over ACM system that starts up with current data and last known item data, then these are REQUIRED.
- tblArchivePosition
- tblItems
- tblObjects
- tblProperties
- *tblServerDirectory : this is only required if you are using the Server Directory function
Historical EFM Data Tables
Historical EFM data is stored in multiple tables. If you replicate your EFM data, you may should also want to replicate the publisher position of publisher pointers to prevent accidental republishing of your data on fail-over.
- tblArchiveRecords
- tblCommStats
- tblLiquidRecords
- tblMeterRecords
- tblMeterRecordsHistory
- tblPublishedRecord
- tblPublishPosition
History Tables
The below These history tables contain no EFM records. They log changes, actions, and errors. Replicating them is optional.
- ErrorLog
- ScheduledJobsHistory
- tblArchiveExec
- tblCommandLog
- *tblChanges : note this table is auto-populate on a trigger from tblObjects and tblProperties
- tblGcWritePendingAudit
- SchedulingErrors
Lookup Tables
The below history This set of tables contain information to help decode records and store the database version information. They do not change between builds, so replication is optional.
- tblDbVersion
- tblGcWriteResultLookup
- tblLookupCommType
- tblLookupPeriod
- tblLookupPollFailCode
- tblLookupPollStatus
- tblLookupRefProp
- tblLookUpTypeID
