Your database is started by using the server parameter file （SPFILE）. You issued this command to change the value of the LOG_BUFFER initialization parameter：  ALTER SYSTEM SET LOG_BUFFER=24M SCOPE=BOTH;  What would be the outcome of this command？（）

• A、The command would return an error because LOG_BUFFER is a static parameter.
• B、The parameter value would be changed and it would come into effect immediately.
• C、You need to restart the database so that parameter changes can come into effect.
• D、The command would succeed only if initialization parameter LOG_ARCHIVE_MAX_PROCESS is set to value 2.
