Hi,

Have a small confusion about the logon.

1) As anyone can start the instance and logon to the DB with - CONN /AS SYSDBA.
Then how the DBA block the user or intruder using this method in PRODUCTION DB?

2) And as same above, any one can use RMAN as below.
RMAN TARGET SYS/SYSDBA@<db name>
How a DBA handle these issue.

3) My DB (Test) is APTECH, I want to create and connect to the Catalog Recovery DB as below, but I'm not able to, please point out where I'm wrong?

RMAN TARGET/catalog SYS/SYSDBA@Aptech

Thanks in advance....

Not true.

The user has to be in a DBA Group and this behavior can be disabled.

>>2) And as same above, any one can use RMAN as below.
Would you give the SYS password to "any one"?
Same as above.


Something like this.

rman TARGET / CATALOG rman/cat@catdb


TARGET = the database to be backedup, identified by ORACLE_SID.
CATALOG = points to the recovery catalog database.

Hi Mahesh,

Thanks a lot, need little more confirmation.

1) Which means every DBA in production DB will get a separate username and password, am I right?.

2) Can you tell me how to block the SYS/SYSDBA logon?

Thanks in advance.

Yes, every DBA should have its own account, SYSTEM should be locked and password invalidated, SYS should never be used, DBA in charge of backup and recovery should have SYSDBA.

Give a very strong and random password to SYS.

Hi Mickel,

Thanks a lot for you are kind help.
Need some more clarifications in production environment for below.

1) what is the meaning of RMAN executable is running on the same host as the test database.

2) How it affects the O/S and NET Authenticate RMAN backup?

Thanks in advance.

Exactly what it is said, you run RMAN on the test database server; what don't you understand in this sentence?

You have not to use @...
You can use OS authenticate connection (that is "TARGET /").
