Controversy regarding "restricted session" mode

Hi,
I am preparing for OCP (DBA F1) exams and have read couple of books for that. But found the following quite controversial.
One book states that, The OSOPER and SYSOPER privilege enables you to change database access to "restricted session" mode.
While another book states that only SYSDBA privilege enables you to change database access to "restricted session" mode.
Same is the case with "alter database backup controlfile" and "alter database [begin | end] backup".
I am quite confused because of this controversy and was wondering what should I do if I encounter a question regarding this in my exams.
Please guide.
latin.

With sysoper privileges (enabled by way of OSOPER os group, or some other way) on a 9.2 system I could do 'startup restrict' but were not allowed to use alter system enable/disable restricted session commands. In fact no alter system ... command, since this would require the system privilege 'alter system'.
Sysoper authorization allows alter database backup controlfile to...
What can we learn from this? When learning the database, you should practice on it! Not only when you're feeling confused. Try a lot. If you think it is easy enough not to try it, you are probably missing something. Practice also let's you pick up goodies along the way.
Good luck with the exam! :)

Detecting Restricted Session mode

Hi,
We are using the RESTRICTED SESSION mode to disable logins during batch runs and backup. We are using JDBC-connection pools for web services.
Since these pools remain connected, no ORA-01035 will be raised when a connection is taken from the pool. It's not a new login.
Is there a way to detect RESTRICTED SESSION mode (eg. by queying a DBA-view)?

Restricted session & Kill Session

Hello everybody,
1) In which case do I need enabled restricted sessions?
2)Where “ALTER SYSTEM KILL SESSION” command will be useful?
Thanks in advance

Hi,
1) In which case do I need enabled restricted sessions?Whenever you want to perform some maintenance operations in your database and you don't want anyone to access the database except user SYS, you can enable restricted session.
2)Where “ALTER SYSTEM KILL SESSION” command will be useful?When you want to kill a session which is no longer responding or hung or doing some long running operation which is disturbing your performance or you want to stop that processing etc.
SalmanHi Salman,
I think you'll find that "restricted session mode" does not limit login ability to only the SYS user as you mention.
As an example, consider the following.

Rather than limiting to only user SYS it limits login ability to users with the RESTRICTED SESSION System Privilege (granted directly or via role).

DMU 2.0 Disable Restricted session

I've just run a conversion from win-1252 to al32utf8 and we noticed that restricted session was not disabled after the conversion had finished. Is this is known bug? I shut the GUI down before I noticed, but there is nothing in the dmu0.log to show that this was attempted.
On dmu1.1 and 1.2 This was never an issue - the conversion would finish disable restricted session: e.g.

To add to Weiran's answer: We have removed disabling the restricted session so that nobody except SYSDBA can connect to the database before it is restarted. The instance restart automatically disables the restricted session (unless you explicitly open the database in restricted session mode).
We request the instance to be restarted as precaution because it is very difficult to guarantee in such a complex system as Oracle Database that the old (stale) database character set information is not cached somewhere in SGA by some existing or future component.
Note, the instance restart in Oracle Database 12c is required for non-CDB databases only. PDB databases need to be closed and reopened. The CDB instance itself does not have to be restarted.
The documentation may not talk about it yet. We will fix it.

Privileged user cannot access restricted session

There is a bug (Doc ID 444120.1) that stops a 10g listener from accepting connections for an instance in "restricted session" mode, even though the user has the required privilege.
The solution is to put (UR=A) in the CONNECT_DATA part of the tnsnames.ora file. However, v1.5.1 of SQL Developer ignores this parameter and still won't allow connections. Can this be fixed in the next version please?
Thanks, Paul

Tablespace doesn't matter, but the owner does. You have to prefix the table with its scheme/owner (OWNER.EXPENSEREPORT), or assign a (public) synonym to it.
Have fun,
K.

Restricted session privilege in 9i and 10g

We recently upgraded from 9.2.0.7 to 10.2.0.3. Oracle 9i allowed a user with RESTRICTED SESSION priv to connect (sqlplus user /@db) when the database was in restricted mode as it should. However, our Oracle 10g database will not allow a user with RESTRICTED SESSION privilege to log in after 'alter system enable restricted session' is executed. The DBA role does not work nor does granting the system privs CREATE SESSION and RESTRICTED SESSION directly to the user. The error I get when trying to log on is ORA-12526. Any advice on how to remedy this would be much appreciated.
what is the alternative to achieve the same in 10g other than locally?
Thanks,
Vishal

From 10g doc (Oracle® Database Administrator's Guide):
Typically, all users with the CREATE SESSION system privilege can connect to an open database. Opening a database in restricted mode allows database access only to users with both the CREATE SESSION and RESTRICTED SESSION system privilege. Only database administrators should have the RESTRICTED SESSION system privilege. Further, when the instance is in restricted mode, a database administrator cannot access the instance remotely through an Oracle Net listener, but can only access the instance locally from the machine that the instance is running on.

Running Job Scheduler in Restricted Session

I want the database to be in Restricted Session while my ETL load is running via the Job Scheduler so that users will not be able to access tables during the load. When I put it in restricted session however all scheduled jobs cease to run. What user needs Restricted Session privilege? Is it DBSNMP? Is this an acceptable practice?
Thanks,
Susan

Hi Susan,
Sorry for the delay in replying, I was testing this out and talking with another developer. It turns out that you are right.
The Scheduler will not begin running any new jobs or new job chain steps while the database is in restricted mode.
This is intended behaviour and there is no workaround for this. The job coordinator will simply not start any new jobs if it sees that the database is in restricted mode.
This design choice was made a long time ago and isn't currently planned to be changed (although there have been some questions about it so it may in future).
Unfortunately you will need to find another way around this.

Executing alter system enable restricted session on RAC nodes

alter system enable restricted session command enables restricted mode only on the node on which it runs. I need that all nodes entering this node after executing this statement.
Please help.

Something like this using ssh and ksh:
export db_name=<your database name as appears in crs_stat>
srvctl status database -d ${db_name} | while read a inst b c d e node
do
ssh -f $node "print $inst | . oraenv; print 'alter system enable restricted session;' | sqlplus / as sysdba"
done
or you using dbms_job (old but easer to tie to instance than dbms_scheduler):
declare
job binary_integer;
begin
for i in (select inst_id from gv$instance)
loop
dbms_job.submit (
job=>job,
what=> 'begin execute immediate ''alter system enable restricted session''; end;',
instance=>i.inst_id

Vmconnect - enhanced session mode - drag & drop

I am trying to drag and drop a file from the host to the guest, but it does not allow this.
The icon on the vm windows indicates I have enhanced session mode working.. i can copy, and paste but just not drag and drop in either direction.
I was under the impression that was possible?

Issues during restricted session

I have placed my database in restricted mode.
I am trying to run a few DML's with one user which has dba role assigned.
When i executed that procedure through shell scripts I got the following error.
ERROR:
ORA-12526: TNS:listener: all appropriate instances are in restricted mode
But Manually i connected to server & connected to that oracle user, i was able to execute those statements perfectly.
How to enable the user to do the same dml's through procedures?
I granted restricted session privilege to that user.

Also, there's a workaround, add "(UR=A)" to the CONNECT_DATA portion of your connect string definition. This is documented in MetaLink Doc ID 444120.1.
For Example:
DFM2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.20.3)(PORT = 1521))
(CONNECT_DATA =
(UR = A)
(SERVICE_NAME = DFM.uservices.umn.edu)

Restricted Sessions

I set the database to be in restricted session by issuing alter system enable restricted session and then tried to login with a userid that has restricted session privileges and I get ora-12526. We just upgrade from 9.2.0.6 to 10.2.0.3 and I know in 9.2.0.6 I was able to do this without any issues. Does anyone know if I need to do anything different in 10.2.0.3 to make this work?

It is an expected behavior:
lsnrctl status
Service "orcl.us.oracle.com" has 1 instance(s).
Instance "orcl", status RESTRICTED, has 1 handler(s) for this service...
Service "orclXDB.us.oracle.com" has 1 instance(s).

Running Chain Job in Restricted Session

I have my normal jobs running is Restricted Session
DBMS_SCHEDULER.SET_ATTRIBUTE('job_name', 'ALLOW_RUNS_IN_RESTRICTED_MODE', TRUE);
I did the same for my chain job. The chain job starts but the first step doesn't start until out of restricted session.
I get this if I try to set_attribute on a program
ORA-27469: ALLOW_RUNS_IN_RESTRICTED_MODE is not a valid program attribute
ORA-06512: at "SYS.DBMS_ISCHED", line 4436

DBLINK not working in restricted session.

Hi
All,
I have just upgraded database from 9.2.0.6 to 10.2.0.3. everything was working before upgradation but after upgradation DBLINK not working in restricted sesion.
it has all the restricted session privilage. and also like after upgradation it is working without restricted session. when I put in restricted session it's not working .it was working under restricted session in 9.2.0.6.
Thanks,
Vishal

From 9.2.0.6 to 10.2.0.3 there is some difference in the privileges granted to the roles. So you need to be aware of the new features before you upgrade.
For instance, in 10g, the CONNECT role only has the CREATE SESSION privilege and has been striped off the following privileges:
CREATE CLUSTER
CREATE DATABASE LINK
CREATE SEQUENCE
ALTER SESSION
CREATE SYNONYM
CREATE TABLE
CREATE VIEW
So, if your DBLINK user had these privileges via the CONNECT role, you need to grant them the privileges again to be able to carry out any related tasks. it may not just be because of the restricted session.

Unable to Serialize ReportClientDocument using "StateServer" session mode

Hello,
In my ASP.NET application, I am using "StateServer" session state mode for maintaining session variables. The problem however is that this mode requires all the objects inside the session variables to be serialized and for some reason ReportClientDocument doesn't seem to be serializable.
Here is the code that's not working:
ceSession = Session.Item("ceSession")
ceEnterpriseService = ceSession.GetService("", "InfoStore")
ceInfoStore = New InfoStore(ceEnterpriseService)
rptAppFactory = ceInfoStore.EnterpriseSession.Interface.Service("", "RASReportFactory")
rptClientDoc = rptAppFactory.OpenDocument(rptId, CdReportClientDocumentOpenOptionsEnum.cdReportClientDocumentOpenAsReadOnly)
Session.Add(rptClientDoc)
At the end of the request it throws an exception
"Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode."
[SerializationException: Type 'CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass' in Assembly 'CrystalDecisions.ReportAppServer.ClientDoc, Version=12.0.1100.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' is not marked as serializable.]
Is anybody having any idea on how to successfully store ReportClientDocument in the session variable by using "StateServer" session state mode?
Thanks

There is a sample that demonstrates serializing the ReportClientDocument [here|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d0a4791b-9d3b-2c10-94a5-86088b6224d4]

my requirement is i have to capture the error records into a file
and i have to write that file on appl. server.
how to capture the error records from error log?
please reply

Hai Saritha,
Usually if there are any errors in CALL TRANSACTION we send those records to SESSION METHOD by using below logic.
eg:
CALL TRANSACTION 'XK01' USING
t_bdcdata MODE 'N' .
IF sy-subrc 0.
PERFORM session_bdc.
ENDIF.
ENDLOOP.
IF s_flag = 'X'.
CALL FUNCTION 'BDC_CLOSE_GROUP'.
ENDIF.
This is subroutine .
FORM session_bdc .
IF s_flag = ' '.
CALL FUNCTION 'BDC_OPEN_GROUP'
EXPORTING
client = sy-mandt
group = 'vcentric'
holddate = filler8
keep = 'X'
user = sy-uname
prog = sy-cprog.
s_flag = 'X'.
ENDIF.
CALL FUNCTION 'BDC_INSERT'
EXPORTING
tcode = 'XK01'
TABLES
dynprotab = t_bdcdata.
ENDFORM. " SESSION_BDC
or we can send the error records on into an flat file by using the below logic.
CALL TRANSACTION 'XK01' USING
T_BDCDATA MODE 'N' MESSAGES INTO T_BDCMSG.
IF SY-SUBRC 0.
APPEND W_UPLOAD TO T_ERROR.
ENDIF.
CLEAR W_BDCMSG.
READ TABLE T_BDCMSG INTO W_BDCMSG INDEX 1.
CLEAR L_MSG.
CALL FUNCTION 'FORMAT_MESSAGE'
EXPORTING
ID = W_BDCMSG-MSGID
LANG = SY-LANGU
NO = W_BDCMSG-MSGNR
V1 = W_BDCMSG-MSGV1
V2 = W_BDCMSG-MSGV2
V3 = W_BDCMSG-MSGV3
V4 = W_BDCMSG-MSGV4
IMPORTING
MSG = L_MSG
EXCEPTIONS
NOT_FOUND = 1
OTHERS = 2.
IF SY-SUBRC = 0.
WRITE:/ W_UPLOAD-NAME1, '----', L_MSG.
ENDIF.
ENDLOOP.
this is subroutine.
FORM ERROR_RECORDS .
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
FILENAME = 'C:/ERROR.TXT'
FILETYPE = 'ASC'
WRITE_FIELD_SEPARATOR = 'X'
TABLES
DATA_TAB = T_ERROR.
ENDFORM. " ERROR_RECORDS
Reward is useful.
