Measurement
Unit |
Interpretation |
| Dynamic_sql_rate
|
Indicates the
number of dynamic SQL statements that were attempted. |
Stmts/Sec
|
This is an
indication of throughput of the system during the monitoring period.
A high value of dynamic SQLs and low value of failed SQLs indicate
good throughput
|
| Select_sql_rate
|
Indicates
the number of SELECT SQL statements that were executed. |
Stmts/Sec
|
This
measure can be used to determine the level of database activity at the
application or database level. This measure is useful for analyzing
the application activity and throughput. |
| Failed_sql_rate
|
Indicates
the number of SQL statements that were attempted, but
failed. |
Stmts/Sec
|
This
measure helps in determining reasons for poor performance, since,
failed statements means resource wastage and lower throughput for the
database. |
| UID_sql_rate
|
Indicates
the number of SQL UPDATE, INSERT, and DELETE statements
that were executed. |
Stmts/Sec
|
This information
can be useful for analyzing application activity and throughput. |
| Pct_failed_sql
|
Indicates the
percentage of SQL statements that failed during the interval. |
Percent
|
A relatively
high value indicates a problem. The percentage of SQL statements that
received a negative SQL code indicates a possible cause of poor
performance. Failed SQL statements waste system resources. Hence, this
value of this measure should be very low. |
| Pct_ddl_sql
|
Denotes the
percentage of SQL statements that are DDL during a specific interval. |
Percent
|
This value
should normally be low. |
| Pct_uid_sql
|
Percentage of SQL
statements that are update/insert/delete during the interval |
Percent
|
This measure can
be used to determine the level of database activity at the application
or database level. |
