|
| Name |
Default value |
Description |
| history threshold |
90 |
The number of days the statistics (size, rows count, fragmentation, etc.) will be kept in the history table. |
| max objects |
10 |
The number of tables for which the statistics will be collected into the history table. |
| size threshold |
50 |
The minimum size (in MB) of the table to be analyzed for fragmentation. |
| max elapsed time |
60 |
The maximum time (in minutes) the procedure is allowed to run. |
| warning threshold |
50 |
Warning threshold value in percent. If the average blocks density (in percent) in the table get below the threshold value, the job will return a warning. |
| alarm threshold |
30 |
Alarm threshold value in percent. If the average blocks density (in percent) in the table get below the threshold value, the job will return an alarm. |
| ignore schemas |
SYS, SYSTEM |
List of schemas (separated by comma) which will be ignored. You can use % (percent sign) to represent wild card characters. |
| enable warnings and alarms |
NO |
If set to “NO” (default), the job will only collect statistics without returning status warning or alarm. Value “YES” will activate alerting. |
| continue on next run |
YES |
If set to “YES” (default) the procedure will continue where it left off. |
| max objects per graph |
5 |
The maximum number of objects visualized in the report graphs. |
| max objects per table |
30 |
The maximum number of objects visualized in the report table. |
| check empty blocks |
NO |
Checks the number of empty (never used) data blocks in the table (column EMPTY_BLOCKS in DBA_TABLES). This column is populated only if you collect statistics on the table using the DBMS_STATS package. If set to “YES” the procedure will execute DBMS_STATS.unused_space procedure on each table. |
| density threshold |
80 |
Tables with higher density then this parameter value are not checked. |
