You can configure Oracle ASM with the Oracle Enterprise Manager Configuration Parameters page similar to the screen shown in Figure 7-2.

To configure the Oracle ASM instance:

1. Access the Oracle Automatic Storage Management home page.

   See "Accessing the Oracle Automatic Storage Management Home Page" for instructions.

2. Click the Configuration link at the top of the page to view the Configuration Parameters page.

3. Update the configuration options on the page as follows:

   • Disk Discovery Path (ASM_DISKSTRING initialization parameter)

     Enter a string value. See "ASM_DISKSTRING".

   • Auto Mount Disk Groups (ASM_DISKGROUPS initialization parameter)

     Enter a string value. See "ASM_DISKGROUPS".

   • Rebalance Power (ASM_POWER_LIMIT initialization parameter)

     Enter an integer value. See "ASM_POWER_LIMIT".

   • Preferred Read Failure Groups (Only in Oracle RAC environments) (ASM_PREFERRED_READ_FAILURE_GROUPS initialization parameter)

     Enter a comma-delimited string of values in which each string represents a failure group. This parameter is generally used only for clustered Oracle ASM instances. See "ASM_PREFERRED_READ_FAILURE_GROUPS".
