Oracle Database Discussions

Hi,
I created a 10g v.2 db using the DBCA...
Having executed the following command:
SQL> alter database backup controlfile to trace as '......' NoResetLogs;
so as to have the capability to re-create the control file in case of its destruction....
I have noticed in the file generated:

...
.....
CREATE CONTROLFILE REUSE DATABASE "INFO" NORESETLOGS  NOARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\INFO\REDO01.LOG'  SIZE 50M,
.....
..... 

But,

alter database add logfile member 'D:\OracleDB_Backup\a','D:\OracleDB_Backup\b','D:\OracleDB_Backup\c' to group 5;
 
Database altered
 
SQL> alter database add logfile member 'D:\OracleDB_Backup\r' to group 5;
 
Database altered

SQL>  select status,type,member from v$logfile where group#=5;
 
STATUS  TYPE    MEMBER
------- ------- --------------------------------------------------------------------------------
        ONLINE  D:\ORACLEDB_BACKUP\A
        ONLINE  D:\ORACLEDB_BACKUP\B
        ONLINE  D:\ORACLEDB_BACKUP\REDO06.LOG
        ONLINE  D:\ORACLEDB_BACKUP\C
        ONLINE  D:\ORACLEDB_BACKUP\R 

Note: I created 5 members in this group... not only 3.

Additionally, when i try to insert another log file member to this log group i get the expected(!) error message:

SQL> alter database add logfile member 'D:\OracleDB_Backup\x' to group 5;
 
alter database add logfile member 'D:\OracleDB_Backup\x' to group 5;
 
ORA-00357:too many members specified for log file, the maximum is 5

Why is there this difference between the maxlogfilemembers written in the trace file (using the backup controlfile....) and the max log file members reported in the error message(ORA-00357)...???

Thank you,
Sim
