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.
Administrative Utilities
The onmode utilityUse the onmode utility to change the database server operating mode and perform various other operations on shared memory, sessions, transactions, parameters, and segments.
onmode -R: Regenerate .infos.dbservername File

onmode -R: Regenerate .infos.dbservername File

The database server creates the .infos.dbservername file when you initialize shared memory and removes the file when you take the database server offline. This file is in the $ONEDB_HOME/etc or %ONEDB_HOME%\etc directory. The name of this file is derived from the DBSERVERNAME parameter in the ONCONFIG configuration file.

The database server uses information from the .infos.dbservername file when it accesses utilities. If the file is accidentally deleted, you must either re-create the file or shut down and restart the database server.

>>-onmode-- -R-------------------------------------------------><


Element	Purpose	Key Considerations
-R	Re-creates the .infos.`dbservername` file	Before you use the -R option, set the ONEDB_SERVER environment variable to match the DBSERVERNAME parameter from the ONCONFIG file. Do not use the -R option if the ONEDB_SERVER environment variable is set to one of the DBSERVERALIASES names.
