Cannot generate AWR/ADDM reports in Oracle 10g

Question

Hi,
We are running 10.2.0.3.0 and troublshooted the performance problem for some queries. But when tried to run AWR/ADDM reports from OEM and got the following messages:
Insufficient Data in Interval. For displaying data on this page, two historical snapshots are needed. Make sure that two snapshots are present in the target database instance. In addition modify the interval so that it is contained within two available snapshots
I checked the scheduled jobs in this DB,
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production
With the Partitioning, Real Application Clusters, Oracle Label Security and Data Mining options
SQL> select JOB_NAME from dba_scheduler_jobs;
JOB_NAME
PURGE_LOG
FGR$AUTOPURGE_JOB
GATHER_STATS_JOB
AUTO_SPACE_ADVISOR_JOB
Has anyone anyidea why AWR/ADDM reports cannot be run? Thanks
Liz

Hi,
If you want you can execute snapshot at your required time as suggested by people.
However Oracle 10g by default take snap at every one hour.
To check
select snap_id, to_char(BEGIN_INTERVAL_TIME,'DD-MON-YYYY HH24:MI') BEGIN_INTERVAL_TIME,
to_char(END_INTERVAL_TIME,'DD-MON-YYYY HH24:MI') END_INTERVAL_TIME
from dba_hist_snapshot
You can generate AWR Report by executing following SQL, Connect as SYS
SQL> @$ORACLE_HOME/rdbms/admin/awrrpt.sql
Input required details it asks, you can get AWR report in HTML or text format.
ADDM Report:
@$ORACLE_HOME/rdbms/admin/addmrpt.sql
