In-Depth Information
The SQL statement parsed is printed on a new line after the line starting with the string
PARSING
IN
CURSOR
. A line starting with
END
OF
STMT
marks the end of the SQL statement. The
mapping from the numeric command type (parameter
oct
) to the command name is available
by running
SELECT
action,
name
FROM
audit_actions
. Table 24-3 contains the most common
command types plus some additional command types that may be used by applications. Please
note that these numeric command types do not correspond with Oracle Call Interface SQL
command codes (
Oracle Call Interface Programmer's Guide 10g Release 2
,
Appendix A
).

PARSE Entry Format
Among other metrics,
PARSE
entries represent CPU and wall clock time consumed by parse
operations. By looking at the parameter
mis
(library cache miss) it is possible to derive the
library cache hit ratio from trace files. A low hit ratio usually indicates that the application does
not use bind variables. Details on the parameters of the
PARSE
entry are in Table 24-4.
