ALTER SESSION COMITT NOWAIT

I have a client / server service which receives messages and inserts log records into a table. There are only inserts and this is not a bulk load operation.
Is there a way to alter the session of the connection with odp.net to commit no wait? From sql developer it is perfectly fine, but I cannot get the connection from the service to alter it's connection.
Thanks,

Hi,
I assume you also logged a SR on this, but if not (or for anyone else that may find this thread) the solution is to add "enlist=false" to your connection string. I'm not sure exactly why the setting is ignored (perhaps the database folks could comment better there) when support for distributed transactions is enabled in the OCI code, but it's not uncommon for that setting to cause a difference in behavior from that of sqlplus.
Hope it helps
Greg

Create view and alter Session gets 0RA-01031

I can't create a view after using ALTER SESSION set current_schema without using an explicit schema. I get ORA-01031. Is this a known bug? Here are the details:
1. Log on as SYSTEM
2. ALTER SESSION set current_schema=FRED;
3. CREATE VIEW vFoo as select * from Foo; -- ORA-01031: insufficient privileges
4. CREATE VIEW FRED.vFoo as select * from Foo; -- this works!
I've read where some privileges need to be granted directly. In fact, if Fred grants select privilege on Foo to SYSTEM, the statement in #3 above works. However, something doesn't seem right because why does #4 succeed without the GRANT?
In case you're wondering why I don't just use #4 above, which does work, it's because I've got a script that will be run by customers to create tables, views, etc. in an arbitrary schema and the schema is associated with a user with limited permissions. Hence, the use of the ALTER SESSION.

See, You looged as SYSTEM (Scheme = SYSTEM)
Now you alter your session to another schema FRED.
Now if you want to access SCHEMA of FRED, You need to connect first.
SQL > connect user/password@host
Then
SQL > CREATE VIEW vFoo as select * from Foo;
View created.

ALTER SESSION in sql script produces strange results

Why would "alter session set NLS_DATE_FORMAT" interfere with the operation of a sql script?
First, the script without the ALTER SESSION:
SQL> !cat doit1.sql
--alter session set NLS_DATE_FORMAT = "DD-MON-YYYY"
set pagesize 99
set trimspool on
col BIRTH_MONTH for a11
break on BIRTH_MONTH skip 1
spo doit.txt
prompt My Membership
set feedback off heading off
select 'As of ' || sysdate from dual;
set heading on
select count(*) from dual;
spool offAnd its execution:
SQL> @doit1
My Membership
As of 14-JAN-10
COUNT(*)
1All's well with the world. Now let's throw in the ALTER SESSION:
SQL> !cat doit2.sql
alter session set NLS_DATE_FORMAT = "DD-MON-YYYY"
set pagesize 99
set trimspool on
col BIRTH_MONTH for a11
break on BIRTH_MONTH skip 1
spo doit.txt
prompt My Membership
set feedback off heading off
select 'As of ' || sysdate from dual;
set heading on
select count(*) from dual;
spool offAnd its execution
SQL> @doit2
set pagesize 99
ERROR at line 2:
ORA-00922: missing or invalid option
COUNT(*)

SQL> Doesn't like the SET commands (I've played around with serveral, it doesn't like any of them) and ignores the opening SPOOL command
I first noticed this with a 10.2.0.1 client (windows) connected to a 10.2.0.4 database (HP-UX). Confirmed on my laptop VM lab, 10.2.0.4 under OEL5, client and db on same VM.

Error ORA-02248 invalid option for ALTER SESSION

Hi All,
I'm using windows vista.I have installed oracle database 11g.Now, SQL Developer is working fine in this.I gave the sid as orcl and gave my username and password in sqldeveloper and it works.
But the host string is not working in forms and sql plus.How do i know which host string i should give??I came to know that the tnsnames.ora which is present in the oracle home directory should be copied to forms directory also.I did that too but still forms,reprorts and sql plus are not working.I get two errors namely ORA-02248 invalid option for ALTER SESSION and TNS could not resolve service name .Pls suggest how to proceed.Thanks in advance....
Regards,
Gowtham

Unfortunately you forgot to mention forms/reports version. Currently only one Developer Suite version is certified on Vista running 11g,don't ignore software/hardware requirements.
It's 10.1.2.0.2 and that package requires additionally patch 6153263.

"ORA-02248: invalid option for ALTER SESSION" -- Urgent request

Hi All,
We use Discoverer 3.1.36.06 and are in middle of a 3i to 10g upgrade for Discoverer for a data warehouse setup. Our databases where upgraded to 10g from 9i and now we get the error message saying:
"ORA-02248: invalid option for ALTER SESSION"
I got some very helpful info abt the prob from the link below.
Discoverer 3i Issue with 10.2.0.3 - ORA-02248
We are mid way through the 3i to 10g upgrade and just need a quick fix for the next 2-3 weeks while the upgrade is finished.
Does any one know if changing the NLS language and applying the post longon trigger on Database id's would help in resolving this connection issue temporarily.
Any advice is deeply appreciated.
Thanks.
Edited by: Paul S on Dec 15, 2008 3:01 PM Corrected the link

Hi,
There are two types of trigger you can use: database triggers and discoverer triggers. You probably want to use a database trigger.
If you are using an APPS mode EUL (ie. logging using Applications username/passwords) then you will be logging in as the APPS database user and the syntax is:
create or replace trigger APPS.disco_logon_trigger after logon ON APPS.SCHEMA
begin dbms_session.set_nls('nls_date_format', '''DD-MON-YYYY'''); end;
If it is a database EUL and the database user is gl_inq then the syntax would be
create or replace trigger gl_inq.disco_logon_trigger after logon ON gl_inq.SCHEMA
begin dbms_session.set_nls('nls_date_format', '''DD-MON-YYYY'''); end;

Hi Joel, Scott and the rest of the community.
I went on determine the import problem. It occurred two more times since the last post.
First time:
This time was a bit different. I wanted to create a new workspace and got the error "ORA-02047: cannot join the distributed transaction in progress" when I clicked on the button to create a new workspace after I entered all information to it.
I restarted the OAS and worked again
Second time:
During an application import the error occurred again and I tried the following things:
As data owner (only one db link exist)
ALTER SESSION CLOSE DATABASE LINK DBMS_CLRDBLINK;Result no open database links to close
As sys (all database links)
-- The following script queries the DBA_DB_LINKS view to access link information:
SELECT * FROM DBA_DB_LINKS;
-- close of all database links
ALTER SESSION CLOSE DATABASE LINK username.db_link_name;
...Result no database links open. Try of import ended with same error.
Check of apex_public_user no (open) db_links. No objects locked.
I had to restart the OAS again.
Any ideas?

Tobias

2248ORA - 02248: invalid option for ALTER SESSION

Hi,
I have an application running for years (written in ORACLIP) without any change.
The application runs fine against Oracle 8 and 9, and now I am trying to run against Oracle 11gR2.
The Oracle11gR2 installation looks fine, I can sucessfully connect to instance using SQLPLUS SYSTEM/MANAGER.
But my old oraclip application, (that are working fine in Oracle 8 and 9), fails to connect to the Oracle11gR2 instance with the error: 2248ORA - 02248: invalid option for ALTER SESSION.
The error occurs in a ORACLIP function (I believe that this function try to execute the ALTER SESSION), but I have not access to the source code.
I want to know if something have changed in Oracle 11gR2 about ALTER SESSION sintax or behaviour.
If not, any idea about some missing or wrong configuration in the Oracle 11gR2 that cause this problem?
How can I get ( to capture / to trace) the exactly ALTER SESSION that fails?
There is a way to make ORACLE 11gR2 to ignore this error and continuing without return a error? Maybe the "ALTER SESSION" is not important to the program.
There is a way to make ORACLE 11gR2 works like an ORACLE 9 or 10 (in order to verify if this problems is about the version or some wrong configuration).
I will apreciate any idea or help.
Thanks in advance,
Luigggye

JDBC Thin - Configuration alter session

Hi,
I need to configure my connection pool in Weblogic Server (10 MP2) so that when establishing connections to the database make an alter session to set the parameter "commit write nowait".
My actual JDBC String is: "jdbc:oracle:thin:@<hostnama>:1521:SID"
Please help me.
Best Regards

Look to the WebLogic Serve documentation on the "InitSQL" option, whereby the pool
will execute your SQL once, for every pool connection when it is made. Assuming the
PL-SQL you need is:
"alter session set commit write nowait"
then set the WebLogic pool InitSQL parameter to
"SQL alter session set commit write nowait"
Verify the PL-SQL first, then prepend "SQL " to it for the initSQL value.
HTH,

How to tell if a user is issuing 'alter session statements'

When I run 'alter session' from sqlplus in my schema, this does not get parsed and go to v$sql or show up in v$open_cursor. I have a user that is running queries from informatica. He says he is passing alter session statements through informatica, I want to see if they actually get there. The person is not real versed in oracle and I don't know informatica.
i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed).
anyway to tell from a data dictionary view or something like that if these were issued by a given session? The queries run for a few minutes, so I have a bit before his session disconnects to query the data. I can't get him to change his code to stay connected. Is there a view that shows parameter changes for a given session?
oracle: 10.2.0.5
4 alter session commands are:
Alter session set sort_area_size=999999999;
Alter session set hash_area_size=999999999;
Alter session set db_file_multiblock_read_count = 128;
alter session enable parallel dml;

i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed). If Informatica connects to Oracle via network, capturing TCP/IP traffic and mining in it may be your last resort.
you can get session's PDML status from
select pdml_status from v$session;
i cant turn on trace cause he connects and disconnects and this would run immediatelythis contradicts to your following statement
The queries run for a few minutes, so I have a bit before his session disconnects to query the data.
I can't get him to change his code to stay connected. Informatica should have debug. Ask him if he can go step by step.

Alter session set NLS_DATE_FORMAT and to_date not working

Hey folks,
for the sake of simplicity let's assume i want to get the current system time from the table dual in a certain format, e.g. 'YY.MM.DD'.
Currently the query
select sysdate from dual;
yields:
07-JAN-08
The desired output should look like this:
08.01.07
So, according to the manual, i tried the following:
alter session set NLS_DATE_FORMAT = 'yy.mm.dd';
No effect, date is still displayed as
07-JAN-08
Even the following query:
select TO_DATE (sysdate, 'yy.mm.dd') from dual;
yields
07-JAN-08
What am i doing wrong here?
Additional information:
-> DB is Oracle 9
-> I am using the Oracle SQL Developer under Ubuntu Gutsy
-> No, i did not forget to commit my commands....:-)
Any ideas?

select TO_CHAR (sysdate, 'yy.mm.dd') from dual;However the alter session command should work:

Hi:
It seems when you are starting RMAN it's executing some commands (one 'ALTER SESSION...'. It's seems to be a batch which has a bad value for SORT_AREA_SIZE. Find it and modify to a proper value as message shows. If you can't find start RMAN by calling directly the executable ($ORACLE_HOME/bin/rman or %ORACLE_HOME%/bin/rman.exe).

Using ALTER SESSION inside a stored procedure.... not a good idea?

Hi,
I have two stored procedures, both of which are used to query a database to find a particular book, based on ISBN. One sproc searches our main product catalogue and the other searches our suppliers feed catalogues. The stored procedures are called from a C# application via a search tool and the user is able to search on either our catalogue or our suppliers. The appropriate procedure is called based on the users choices.
However, the following behaviour is observed
I search for an ISBN (is a varchar2 field, as isbn's may contain an X if the checksum digit equates to 10) on a feed, so uses the FEED SPROC. The book is found and returned to the app in about 0.5 seconds. I can repeat this as often as i like on different books etc. always works fine.
I then do the same search but against our own catalogue, so uses our CATALOGUE SPROC. Again the book is found quickly, and the search can be repeated with the same results.
If i then go back and run our FEED SPROC then the search time increases to about 3 minutes !
Both the feed and our catalogue is in the same database, although different schema's the connections will be pooled through our app server.
I can repliacte this every single time. I think i have narrowed doen the cause of this behaviour to a few lines of code in our CATALOGUE SPROC:
-- store values
select value into v_vch_NLS_COMP from nls_session_parameters nsp where nsp.parameter = 'NLS_COMP';
select value into v_vch_NLS_SORT from nls_session_parameters nsp where nsp.parameter = 'NLS_SORT';
-- Ensure case insensitivity throughout
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_COMP = LINGUISTIC';
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_SORT = BINARY_CI';
do other stuff
-- restore session variables
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_COMP = ' || v_vch_NLS_COMP;
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_SORT = ' || v_vch_NLS_SORT;
If i remove this code then all is well, so i am assuming that using ALTER SESSION inside a stored procedure is the cause of the problem as it would be changing the execution plan of the FEEDS SPROC in some manner? Any ideas? I know i can just rewrite the sproc to avoid using this coding, but wanted to understand if i am doing something wrong by using ALTER SESSION in this manner?
Any pointers would be appreciated.

Hello (and welcome),
It may be a case of having to create a linguistic index to facilitate the queries once you set these session level parameters, i.e..,
CREATE INDEX idx_01 ON tab ((NLSSORT(col1, 'NLS_SORT=BINARY_CI'))It would appear that the setting of those parameters is invalidating index searching on the current indexes.

Oracle Alter Session not working in CF9

Hello,
I'm trying to understand differences between CF5 and CF9 when I retrieve numbers and dates from an Oracle Database.
The code I ran on CF5 and CF9 servers :
<cfoutput>
<cftransaction>
<cfquery datasource="intranet">
alter session SET NLS_TERRITORY = FRANCE
</cfquery>
<cfquery name="qry" datasource="intranet">
select
     TO_NUMBER(12345/10) as nbr,
     sysdate as dt,
     TO_CHAR(1234.56,'L99G999D99') as cur
from dual
</cfquery>
</cftransaction>
#qry.nbr#<br>
#qry.dt#<br>
#qry.cur#
</cfoutput>
I've got those outputs :
Result in CF5
Result in CF9
1234,5
01/12/09
¿1.234,56
1234.5
2009-12-01 19:16:04.0
¿1.234,56
The first two rows in CF5 display data in French format. That's not the same for CF9, the data are in American format.
Then I changed the NLS_TERRITORY parameter
alter session SET NLS_TERRITORY = AMERICA
Result in CF5
Result in CF9
1234.5
01-DEC-09
$1,234.56
1234.5
2009-12-01 19:20:39.0
$1,234.56
The two first row haven't changed in CF9, it seems that the "alter session" has no effect on number and date format in query results. Is that a bug or am I misunderstanding something ?
Regards,
Maxime

Thank you for your reply.
I tried what you've suggested on the CF9 server.
The results are :
NLS_TERRITORY =
1) oracle JDBC database
2) oracle JDBC thin client
3) oracle JDBC-ODBC bridge
AMERICA
1234.5
2009-12-02 13:24:30.0
$1,234.56
1234.5
{ts '2009-12-02 00:00:00'}
$1,234.56
1234.5
2009-12-02 13:24:30.0
$1,234.56
FRANCE
1234.5
2009-12-02 13:29:53.0
¿1.234,56
1234.5
{ts '2009-12-02 00:00:00'}
¿1.234,56
1234.5
2009-12-02 13:29:53.0
¿1.234,56
The behavior is pretty much the same in the three differents ways to call the database. The only difference is on the date display using the Oracle JDBC thin client, which is another format from those I've already got.

Execute immediate 'alter session set current_schema = ' failed in PL/SQL

Hi
I am trying to run

The user who owns the procedure needs to be granted direct select rights on table test.solutions (not via a role). Still will not help. Look what OP is trying to do. In a stored procedure owned by some user (other than TEST) OP is trying to reference user TEST owned table solution without prefixing it with owner. Something like:

SQL> However, OP tries to do it in a SP using dynamic SQL to change current schema to test. Such change will occur when SP will be executed, not when is it compiled. At compile time we are still under SP owner's schema and therefore select from solutions implies table solutions owned by SP owner, not by TEST. The only way to make SP compile and work OK is to select from solutions also dynamically:
