The syntax for optdiag is:
optdiag [binary] [simulate] statistics {-i input_file | database[.owner[.[table[.column]]]] [-o output_file]} [-U username] [-P password] [-I interfaces_file] [-S server] [-v] [-h] [-s] [-Tflag_value] [-z language] [-J client_charset] [-a display_charset]
You can use optdiag to display statistics for an entire database, for a single table and its indexes and columns, or for a particular column.
To display statistics for all user tables in the pubtune database, placing the output in the pubtune.opt file, use the following command:
optdiag statistics pubtune -Usa -Ppasswd -o pubtune.opt
This command displays statistics for the titles table and for any indexes on the table:
optdiag statistics pubtune..titles -Usa -Ppasswd -o titles.opt
See Utility Programs Manual for your platform for more information on the optdiag command. The following sections provide information about the output from optdiag.
