Show Information on Databases with infodb
The infodb utility shows administrative details about databases, such as the directory names of data, checkpoint, journal, dump, and work locations. These details are stored in the configuration file.
To use infodb
To get a list of databases, issue the following command at the operating system prompt:
infodb -databases
or
infodb -get_dbname
Issue the following command to see all information from all databases, including the system databases iidbdb and imadb:
infodb
Infodb prints a report for each database in the installation. To restrict the information to a specific database, specify:
infodb dbname
The following is sample output (on Windows) for the test2 database:
