4.3 Determining if an Oracle Home is Read-Only
By default, an Oracle Database installation configures all Oracle Database homes in a read-only mode. You can use the Registry Editor to determine if your Oracle home is a read-only Oracle home.
Start Registry Editor and navigate to the ORACLE_HOME_READONLY
entry in the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OracleHomeName
Windows Registry key.
The default value for the
ORACLE_HOME_READONLY
parameter appears as Y
in a read-only mode. Do not modify this value.
