lslpp -L VRTSdbed


The dbed_checkconfig command verifies various elements of the environment for an Oracle database.

The command attempts to use certain basic rules on Oracle settings, file system parameters, volume parameters, and layout options to verify how resilient and well configured an Oracle database environment is. The information provided is valid for the supplied Oracle database (ORACLE_SID). All output is sent to stdout.


The following options are supported:
Specifies the name of the Oracle database.
Specifies the ORACLE_HOME setting for the ORACLE_SID database.
Sets verbose mode. If ODM is not present, specifies which datafiles are not Quick I/O files. If ODM is present, then -v specifies which Quick I/O files need to be converted to regular VxFS files in order to use ODM features. Also specifies the datafiles that are not configured for autoextend.
Disables SFDB repository refresh. By default, dbed_checkconfig will refresh the SFDB repository if this option is not used.
Shows command usage.
Sets interactive mode.
