Replication

Data replication is a powerful FairCom DB feature providing near real-time data availability between one or more servers. These options configure specific attributes of this optional feature.

 
MAX_REPL_LOGS (MAX_REPL_LOGS, MAX_REPL_LOGS)

Changes the limit FairCom Server sets for the number of active transaction logs that are kept for Replication Agent processing.

 
REPLICATE

Specifies which files are required to be replicated via the Replication Agent.

 
REPL_IDENTITY_USE_MASTER

Forces the local FairCom DB process to use the serial number value from the master server when adding a record to a local replica.

 
REPL_IDENTITY_USE_SOURCE

Forces the target FairCom DB process to use the identity field value from the source server when adding a record to a replicated file.

 
REPL_MAPPINGS

Specifies a local filename mapping to a master server.

 
REPL_NODEID

Sets the replication node ID of a local c-tree Server.

 
REPL_READ_BUFFER_SIZE

Sets the size of the replication log read buffer.

 
REPL_SRLSEG_ALLOW_UNQKEY

Forces FairCom DB to allow an index that contains a SRLSEG segment to be the replication unique key.

 
REPL_SRLSEG_USE_MASTER

Forces a local FairCom DB process to fill in the serial number value from the master FairCom DB process when adding a record to a local replica.

 
REPL_SRLSEG_USE_SOURCE

Forces a FairCom DB process replication writer thread to fill in the serial number value from the source server when adding a record to a replicated file to preserve existing serial numbering.

 
Diagnostics

Diagnostics keywords are intended to be used to help collect data to be analyzed for troubleshooting. The use of these keywords should be avoided in normal operation as they may cause additional overhead (e.g., logging).

 
DIAGNOSTICS REPLICATE

Enables FairCom DB to log messages to CTSTATUS.FCS when a file that is being created or opened matches the filename specified for the REPLICATE keyword, and it does not meet replication requirements.
