comment Oracle remote OS authentication, security risks with domain users
I renamed my laptop computer to KA, so computer name is KA. Created local user MARIK. Switched off my network cable from my work computer, which is in domain and plugged it into my laptop. Set the same ip as it had my work compuer. Logged on to the computer by MARIK user. When I run whoami, it shows me KA\MARIK. Created user "OPS$MARIK" in my database and tried to connect from laptop without password and username. ORA-01017 happend. So by some way oracle check if user is a domain user or local user. One more thing to note. If you create user "OPS$MARIK" you can logon but not "OPS$LB\MARIK"

It is not using multi-path. How to check what you said? ("O.S. does not point to the file system instead of the disk groups")

@Colin'tHart I have changed permissions but still not working. Maybe there is the problem with virtual disk, but don't know how to check.

comment What problems can be caused by dropping a rollback segment manually?
my spfile contains the following: crimesys1.undo_tablespace='UNDOTBS1' *.undo_tablespace='UNDOTBS' UNDOTBS is newly created undo tablespace, which I want to leave and delete other undo tablespaces.

@MindaugasRiauba dba_2pc_pending is empty now but, there is sometimes a record in gv$transaction referring to some of these segments.

@Phil Why do you think that shutdown abort may resolve the issue?

comment What problems can be caused by dropping a rollback segment manually?
@Phil I changed UNDOTBS2 to any available undo tablespace name and still returns 0 rows. Maybe, it is now that no one uses, but will be used after a while.

comment What problems can be caused by dropping a rollback segment manually?
When I query status column of dba_rollback_segs view, filtering by UNDOTBS2, it shows me that most of them are OFFLINE and others are PARTLY AVAILABLE. If I drop OFFLINE segments, why it should be a problem?

comment ORA-13901 Object UNDOTBS01 was not found. ORA-06512: at “SYS.DBMS_SERVER_ALERT”, line 7
@Phil I have the full installation of 11.2.0.3. Can I upgrade my 11.2.0.1 database using this installation? Or do I need to download the patch? Is the patch software different from the fresh installation? Does runInstaller of the fresh installation have the option like upgrade? And is the patch(11.2.0.1->11.2.0.3) different from the patch(11.2.0.2 to 11.2.0.3)?
