AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's ReferenceThe HCL OneDB™ Administrator's Reference includes comprehensive descriptions of HCL OneDB™ configuration parameters, the system-monitoring interface (SMI) tables in the sysmaster database, the syntax of database server utilities such as onmode and onstat, logical-log records, disk structures, event alarms, and unnumbered error messages.
Configuring and monitoring HCL OneDB™
Database configuration parametersThe HCL OneDB™ database server uses a configuration file, which is called the onconfig file, during initialization. This file contains default configuration parameter values. You can modify the parameter values to improve performance and other characteristics of the instance or database.
IFX_XA_UNIQUEXID_IN_DATABASE configuration parameterUse the IFX_XA_UNIQUEXID_IN_DATABASE configuration parameter to enable the transaction manager to use the same XID to represent global transactions on different databases in the same database server instance.

IFX_XA_UNIQUEXID_IN_DATABASE configuration parameter

Use the IFX_XA_UNIQUEXID_IN_DATABASE configuration parameter to enable the transaction manager to use the same XID to represent global transactions on different databases in the same database server instance.

onconfig.std value: None
default value: 0
values: 0 = disabled; 1 = enabled
takes effect: After you edit your onconfig file and restart the database server.

Usage

An XID is a global transaction ID for a distributed XA transaction.

If you set the IFX_XA_UNIQUEXID_IN_DATABASE configuration parameter to 1, the database server allows the transaction manager to use the same XID to represent global transactions on different databases in the same database server instance. Thus, the database can be the domain instead of the server.
