Modifying instance configuration

Use this task to modify the configuration settings for an instance. You can also modify the settings for the PATROL database account on an instance. This account is used to configure PATROL to monitor instances.

Before you begin

Review the results of modifying an instance configuration, as shown in the following table.

PATROL account modification results

To modify instances

1. From the ORACLE menu, choose Configuration > Advanced > Instance Modify.
   The Modify Instances dialog box displays all configured instances.
2. Select the instance that you want to modify and click Accept.
3. In the Privileged Account Information dialog box, enter the name and the password for the privileged account to use to access the Oracle account for PATROL and click Apply.
   PATROL uses this account to modify the PATROL account and the PATROL database objects. You can use either the SYS account for the instance or a DBA account.
   The account username and password are verified, and messages inform you of any problems or errors.
4. Click Exit to close the Privileged Account Information dialog box.
5. In the Database Account dialog box, type the following information:
   
   1. • the user name and password for the PATROL account
      • the default tablespace for the PATROL account
      • the temporary tablespace for the PATROL account
      • the user Profile for the PATROL account

   Note

   If you want you can also use the TEMP group name instead of the TEMP tablespace. 

6. Select or clear the Enable Instance Monitoring, Always On Line and Enable OS Authentication check boxes.
   • If you select Enable Instance Monitoring, the instance is discovered and monitored by PATROL. If you do not select this check box, the instance is configured and discovered, but you must explicitly enable monitoring on the instance.
   • If you select Always On Line, PATROL goes into an alarm state if the instance goes offline for any reason.
   • If you select Enable OS Authentication, the instance is modified. This instance was originally configured by using automatic configuration feature. The Enable OS Authentication option authenticates your PATROL account.
7. Select the categories that you want monitoring the instance. To enable all categories, select Select All Categories, or you can select individual categories from the list.
   AVAILABILITY and COLLECTORS are the default categories for all instances. These categories are always enabled, and they do not appear on the list.
8. Click Apply.
   Depending on what you have changed, PATROL modifies the account or objects.
9. Click Exit to close the Database Account dialog box.
10. Click Exit to exit this function.
    After you have modified the instance, the instance is automatically discovered or its icons is deleted according to their monitoring status.

Where to go from here

If you have configured the instance but did not enable monitoring, you must enable the monitoring for the instances. Go to Enabling and disabling Oracle instance monitoring.
