Answer 1

Ok then
if you want to change retention settings in 10.2.0.2 , not possible without applying patch
3900473

And in 10.2.0.3, this is how you go
However, if you plan to extract or review the raw or aggregated data using data analysis tools other than Enterprise Manager, you may want to increase the amount of raw or aggregated data available in the repository. You can accomplish this by increasing the retention times for the raw or aggregated data.
To modify the default retention time for each level of management data in the repository, you must insert additional rows into the MGMT_PARAMETERS table in the repository database. Table 8-3 shows the parameters you must insert into the MGMT_PARAMETERS table to modify the retention time for each of the raw data and aggregate data tables.
Table 8-3 Parameters for Modifying Default Data Retention Times in the Management Repository
MGMT_METRICS_RAW mgmt_raw_keep_window 7 days
MGMT_METRICS_1HOUR mgmt_hour_keep_window 31 days
MGMT_METRICS_1DAY mgmt_day_keep_window 365 days
For example, to change the default retention time for the table MGMT_METRICS_RAW from seven days to 14 days:
1. Use SQL*Plus to connect to the repository database as the Management Repository user.
The default Management Repository user is sysman.
2. Enter the following SQL to insert the parameter and change the default value:
INSERT INTO MGMT_PARAMETERS (PARAMETER_NAME, PARAMETER_VALUE) VALUES ('mgmt_raw_keep_window','14');
