Last updated on DECEMBER 06, 2016

Oracle Database - Enterprise Edition - Version 10.2.0.4 and laterInformation in this document applies to any platform.

Symptoms
Tablespace has hit the threshold percentage yet no alert is seen.
The tablespace usage is correctly reported in dba_tablespace_usage_metrics, however
no alert is seen in DBA_OUTSTANDING_ALERTS and hence no alert is reported on
the Grid Control Metric Page.
Example:
Check the tablespace usage
SQL> select * from dba_tablespace_usage_metrics where tablespace_name = 'DUMMY';
TABLESPACE_NAME USED_SPACE TABLESPACE_SIZE USED_PERCENT
DUMMY 23 25 92
TABLESPACE_NAME USED_SPACE TABLESPACE_SIZE USED_PERCENT
DUMMY 23 25 92
Check the current threshold settings
SQL> SELECT "METRICS_NAME",
"WARNING_OPERATOR" WARN_OP, "WARNING_VALUE" WARN_VAL,
"CRITICAL_OPERATOR" CRIT_OP, "CRITICAL_VALUE" CRIT_VAL,
"OBJECT_TYPE" OBJ_TYPE,
"OBJECT_NAME" OBJ_NAME,
"STATUS"
FROM "SYS"."DBA_THRESHOLDS"
WHERE metrics_name like '%Tablespace%';

Check the outstanding alerts
SQL> SELECT "OBJECT_NAME", "OBJECT_TYPE", "REASON",
"SUGGESTED_ACTION", "ADVISOR_NAME",
"METRIC_VALUE", "MESSAGE_TYPE", "MESSAGE_LEVEL",
"INSTANCE_NAME",
"INSTANCE_NUMBER", "ERROR_INSTANCE_ID"
FROM "SYS"."DBA_OUTSTANDING_ALERTS"
WHERE reason_id=9;
No rows selected
"SUGGESTED_ACTION", "ADVISOR_NAME",
"METRIC_VALUE", "MESSAGE_TYPE", "MESSAGE_LEVEL",
"INSTANCE_NAME",
"INSTANCE_NUMBER", "ERROR_INSTANCE_ID"
FROM "SYS"."DBA_OUTSTANDING_ALERTS"
WHERE reason_id=9;
No rows selected
As per threshold settings we should have seen an alert for the tablespace DUMMY however it is not reported in the outstanding alerts.
