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.

oncheck -pB: Display blobspace statistics

>>-oncheck---- -pB----database--+-------------------------------------+-><
                                '-:--+--------+--table--+-----------+-'   
                                     '-owner.-'         '-,frag_dbs-'

The -pB option displays statistics that describe the average fullness of blobspace blobpages in a specified table. These statistics provide a measure of storage efficiency for individual simple large objects in a database or table. If you do not specify a table or fragment, the option displays statistics for the entire database. For more information, see optimizing blobspace blobpage size in the chapter on managing disk space in the HCL OneDB™ Administrator's Guide.
