## -24976: ERR_PARAMEXIST - param file of database already exists

### Explanation:

A parameter file already exists for the specified database instance. The parameter file can be initialized only if no parameter file exists. This prevents the configuration from being lost.

### User Action:

Delete the parameter file explicitly either at file-system level or using the DBM command param_rmfile. Note that this will mean the current database instance configuration will be lost.
