To use ORADIM to modify an instance, enter:

oradim -EDIT -SID SID | -ASMSID SID [-SYSPWD password] [-STARTMODE auto | 
manual] [-SRVCSTART system | demand] [-PFILE filename | -SPFILE][SHUTMODE normal 
| immediate | abort] [SHUTTYPE srvc | inst | srvc,inst]

For this command, note the following:

• -EDIT indicates that you are modifying an instance. This is a mandatory parameter.
