Figure 5-18. SSP issuing an error So what has happened here If you examine the URL that was used, you will see that an additional parameter has been added (the session ID is shortened to 123 here just for readability of the example): f p=108:3:123::::P3_ID:9&cs=3E597ACB57167BF929355A86561141926 The cs parameter is the checksum, which is calculated based on the items and values that have been set by the application when building the URL. This checksum is then recalculated when the new page is being processed, and if the recalculated checksum does not match the checksum passed in the URL, an error is raised. So, with very little effort, you have prevented users from being able to modify the URL to access records that they should not be able to access. If you look back at the settings that were made for your application by the SSP wizard, you will see that for the Update Bug screen, each page item is set to Checksum Required Session Level, as shown in Figure 5-19. Therefore, when the user tries to modify the value of the P3_ID page item, which is protected by a checksum, the SSP functionality kicks in and issues the error you saw.

Both the interval and retention parameters should be specified in minutes. If you specify an interval of 0, Oracle will set the snapshot interval to 1 year; if you specify a retention period of 0, Oracle will set the retention period to 100 years. You can take a snapshot manually at any time for the particular instance you are connected to using the CREATESNAPSHOT procedure at the SQL*Plus prompt, for example: S0L> EXECUTE dbms_workload_repository.create_snapshot; This procedure can accept a single parameter specifying the flush level for the snapshot, which is either TYPICAL or ALL. You can also create snapshots from within EM; this functionality is available by navigating from the Administration page to the Workload Repository page and then to the Snapshots page. When you have a stable workload, you can take a baseline, which records the difference between two snapshots. First, identify a suitable pair of snapshot IDs using the DBA_HIST_SNAPSHOT view: S0L> SELECT snap^id, instance^number^ startup^time, > begin_interval_time,end_interval_time > FROM dba_hist_snapshot; Both snapshots must belong to the same instance and also have the same instance start-up time. For example, assuming that the start and end snapshots for the period of interest are 234 and 236, you can generate a baseline as follows: S0L> EXECUTE dbms_workload_repository.create_baseline > (> start_snap_id => 234, > end_snap_id => 236, > baseline__name => 'Morning Peak' -

> );

You can check the current baselines in the DBAHISTBASELINE view. Unlike automatic snapshots, which will be purged at the end of the retention period, baselines will not be removed automatically. Baselines can be removed manually using the DROPBASELINE procedure:

Page and item protection in the wizard Now that you ve seen how to protect your application from URL manipulation by using the defaults in the wizard, let s look at the four attribute categories you can protect with SSP: Page access protection Application item protection Page data entry item protection Page display-only item protection
