Oracle10g Grid Computing with RAC
Chapter 6 - Install, Configure and Database Creation

Creating RAC Database with DBCA

a). You cannot modify the SID in the Instance column.

b) You can alter the self-tuning parameters with this dialog. However, setting these parameters to inappropriate values will disable the Oracle self-tuning features.

c) You cannot specify instance-specific values for global parameters with the DBCA.

Once you complete your entries in the All Initialization Parameters dialog, click on Close. Make sure that your entries for the File Locations tab and the other tabs are correct for your RAC database, and then click Next, and the DBCA will display the Database Storage page.

If you selected a preconfigured database template, such as the General Purpose template, then the DBCA will display the control files, datafiles, and redo logs on the Database Storage page.

Select the folder and the file name underneath the folder to edit the file name. However, if you selected the New Database template, the template is without datafiles, and the DBCA displays the control files, tablespaces, datafiles, and redo logs. To change the tablespace properties, such as the datafile or the tablespace size, click the tablespaces icon to expand the object tree and click the tablespace.
