Enterprise Replication Configuration Parameters

The following configuration parameters apply to Enterprise Replication. For more information, see the IBM Informix Dynamic Server Enterprise Replication Guide.

Configuration Parameter

Description

CDR_DBSPACE

Specifies the dbspace where the syscdr database is created.

CDR_DSLOCKWAIT

Specifies the number of seconds that the Datasync (data synchronization) component waits for database locks to be released.

CDR_ENV

Sets the Enterprise Replication environment variables CDR_LOGDELTA, CDR_PERFLOG, CRD_ROUTER, or CDR_RMSCALEFACT.

CDR_EVALTHREADS

Specifies the number of grouper evaluator threads to create when Enterprise Replication starts and enables parallelism.

CDR_MAX_DYNAMIC_LOGS

Specifies the number of dynamic log file requests that Enterprise Replication can make in one server session.

CDR_NIFCOMPRESS

Specifies the level of compression that the database server uses before sending data from the source database server to the target database server.

CDR_QDATA_SBSPACE

Specifies the list of up to 32 names of sbspaces that Enterprise Replication uses to store spooled transaction row data.

CDR_QHDR_DBSPACE

Specifies the location of the dbspace that Enterprise Replication uses to store the transaction record headers spooled from the send and receive queues.

CDR_QUEUEMEM

Specifies the maximum amount of memory that is used for the send and receive queues.

CDR_SERIAL

Controls generating values for SERIAL and SERIAL8 columns in tables defined for replication. Use this parameter to generate SERIAL column primary keys.

CDR_SUPPRESS_ATSRISWARN

Specifies the Datasync error and warning code numbers to be suppressed in the ATS and RIS files.

ENCRYPT_CDR

Specifies the level of Enterprise Replication encryption.

ENCRYPT_CIPHERS

Specifies the ciphers to use for Enterprise Replication encryption.

ENCRYPT_MAC

Specifies the level of message authentication coding to use with Enterprise Replication encryption.

ENCRYPT_MACFILE

Specifies the message authentication coding key files to use with Enterprise Replication encryption.

ENCRYPT_SWITCH

Defines the frequency at which ciphers and secret keys are re-negotiated for Enterprise Replication encryption.
