Dbadmin maintains the database catalog. Each invocation of dbadmin either adds, updates or deletes a database entry from the catalog, or provides catalog information on existing entries. One of the following flags must be specified to indicate the operation to be performed: -a Adds an entry for dbname to the database catalog. dbname gives the name of the database. It can be up to 32 characters long and should not contain blanks. An entry in the database catalog cannot already exist for dbname. Homedir names the home directory for the database. This directory must be an absolute pathname that exists prior to performing this operation. The optional flags -C and -L are available to initialize catalog fields. The -C flag initializes the description catalog field. If it is omitted, the description is set to null. The -L flag names the optional logfile that is stored in the database catalog. If it is omitted, the logfile is set to null. -c Creates the database dbname. An entry in the database catalog cannot already exist for dbname. In addition to adding an entry to the database catalog, dbadmin also creates the home directory for the database in directory. Directory names the absolute pathname of a directory in which the new database is to be created. Obviously, in order for this to work, the named directory must already exist. Once created, dbadmin writes the home directory generated for dbname on standard output. The database name dbname can be up to 32 characters long and should not contain blanks. If the name is too long for a directory entry, a shorter name is generated. If a file or directory already exists in the named directory, a new unique name is configured. The flags -C and -L are available to initialize catalog fields. -d Deletes the database entry for dbname from the database catalog. This does not remove the actual database, only the database catalog entry. Before a database entry can be removed, all logical RMSfiles, reportfiles and formfiles for that database must be removed. With the -d flag, only users that can remove the home directory of dbname can remove the database entry from the database catalog. -f Displays all logical RMSfiles currently defined for the database dbname. With the -v flag, the descriptions for each logical RMSfile is displayed. In addition, titles are printed showing the catalog fields displayed. With the -v flag, omitted, just the logical RMSfile names are printed. -h Displays on standard output the absolute pathname of the home directory for the database dbname. If the named database is not defined, only a new line character is printed. -l Displays all databases currently defined in the database catalog. Including the -v flag, titles for all selected printfields are displayed. With no printfields selected,the default listing is the description of each database in addition to its' name. Print-fields selects the catalog field information displayed for each database. The print-fields available for the database are dbname, home, logfile, and desc. -r Displays the catalog field information for a database entry. Including the -v flag, titles on all selected printfields are displayed. With no printfields selected, the default listing is the description of the database dbname along with its' name. Printfields selects the catalog field information displayed for a database. The printfields available for a database are dbname, home, logfile, and desc. -u Updates the catalog entry for the defined database dbname. At least one of the optional flags (-C, -H, or -L) must be supplied when updating a database entry. The meanings of the optional flags are: -v Displays progress information on standard output. -x Displays on standard output the commands run by dbadmin. -C comment Supplies the description of dbname that is recorded with the database catalog entry. This description is not needed or used by the system. The argument comment is required with the -C flag and must be quoted if embedded with blanks, tabs or newlines. If this flag is omitted when adding or creating a database, the description is set to null. If this flag is omitted when the update (-u) flag is specified, the description for the database is unchanged. -H homedir Names the home directory pathname for the database dbname. This option is used only with the update (-u) flag. Homedir must be specified as an absolute pathname (e.q. /usr/cbase/demo and must exist before attempting to change the home directory for dbname. When determining the pathname of a logical file, if the logical file's pathname is a relative pathname, the home directory is prepended to the logical file's pathname. -L filename Names the pathname for a file used in recording changes made to any logical RMSfile defined for dbname. When adding or updating a database entry, the file used for logging must exist prior to running this command. When creating a database with the -c flag, the logfile is created. The filename can be specified as an absolute pathname (e.q. /usr/cbase/demo/logfile), or a pathname relative to the home directory of the database. When the named database is opened, or a logical file within the database is opened for writing, the specified logfile is opened. If no log file is given, no transaction logging is done for the database.
dblist(C-1), dbfile(C-1), dbhome(C-1), dbadd(C-1), dbcreate(C-1), dbremove(C-1), dbrm(C-1), dbupd(C-1).
Dbadmin performs the operations of dblist(C-1), dbhome(C-1), dbadd(C-1), dbcreate(C-1) and dbremove(C-1). The binary program for dbadmin is copied to each of the above programs for backwards compatibility. In addition, for all programs copied from the dbadmin program, each one has a corresponding resource file copied from the dbadmin resource file (/usr/ cbase/lib/cbase/resource/dbadmin.r)
