ALTER session set current_schema

• 'ALTER SESSION SET CURRENT_SCHEMA' does not work

  Hello
  
  in my JAVA application, I need to change a user's session so that it gets access to the tables that are created by the user 'myUser' (see code below).
  
  The code below shows how I tried to implement with JAVA:
  
  ---------------------------------------------------------------------------------------------------------
  Statement stmtSchema = con.createStatement ();
  String sql = "ALTER SESSION SET CURRENT_SCHEMA = myUser;"
  check int = stmtSchema.executeUpdate (sql);
  ---------------------------------------------------------------------------------------------------------
  
  There is no exception later when running the program, but it seems that the SQL in JAVA command will have no effect because when the program tries a SELECT statement after the session I get an exception:
  
  Java.Sql.SqlException ora-00942: table or view does not exist
  
  This means that the current_schema has not yet changed.
  
  When I tried the same command with sqlplus, it works fine.
  
  Why it does not work with JDBC?
  
  We use 8.1.3 of Oracle and Oracle 10g Release 2.

  Hello
  just a validation test. You guarantee that the alter session command and the select statement is belonging to the same connection object?
  If the connection object is the same you can post a simple test cases for further investigation?

• Inverse of command 'ALTER SESSION SET.

  Hello

  I have a READER user and when I connected with this user that I can set the current session settings such as

  alter SESSION set smtp_out_server = '123.345.134.123';
  
  

  or

  alter session force parallel query parallel N;
  
  

  If it would be sysdba or any other user with grant on parameter $ v we could use:

  select value from v$parameter where name = 'smtp_out_server'
  
  

  Is it possible that I can get the current session settings without going through subsidies on the parameter $ v?

  PS: it seems strange, that we have the setter (alter session set), but haven't Get accessor.

  Maybe the function dbms_utility.get_parameter_value, assuming that you have the privileges.

• Several alter session and SQL * Net message from dblink in APEX

  We have recently to load a new language, but I'm not sure that this is the main problem.

  
  

  
  

  I think that you have the link db in the workspace schema and data requested by the Apex of this link. For example, it may be

  report which uses db link. Check dba_db_links or user_db_links for the existing links. Check if this link used by Apex.

• ALTER session nls_date_format not retained

  Hello guys,.

  Here is the environment:

  Oracle 11.2.0.1 on Linux 64-bit RHEL DB

  Oracle 11 g 2 on Windows 2008 R2 32-bit client

  Our product works service (code generated in c ++) and the service opens 5 sessions of database and alter session set nls_date_format questions to HH24:MI:SS DD/MM/YYYY in each of them.

  But searching through the service logs, I see that select statements (to_char (date)) return date in format other than what has been defined via "alter session" i.e. they do not see the part and just JJ-LUN-AA. But the same select instructions out the date in the format of correct/expected (according to alter session statement).

  The problem is that we do an insert in a table taking the current system time and running to_date (< time system >). It is a failure with: ORA-01843: not one month valid. I understand that it must specify a format for the input string, the date system, but we do not and was not a problem for someone else.

  I'm also no disconnected sessions or reconnects.

  Customer Oracle NLS_LANG is: AMERICAN_AMERICA. UTF8.

  This problem occurs for one of our customers who use this product. All other clients do not encounter this problem, as this has been a long-standing code. I'm not saying that the code is perfect and looking at some of the SQLs, we rely on implicit conversion of data in Oracle instead of editing the SQL code, but this has never caused a problem to any other customer.

  I understand the hierarchy of setting NLS_DATE_FORMAT i.e. the database, register of operating system of the customer, the customer Oracle (alter session) and finally to_date/to_char functions.

  It seems that the session format game becomes overloaded as when they restart the service in our product everything is back to normal until a couple of days, when queries in the service connects begin to show the date incorrect without time portion and just JJ-LUN-AA.

  Any help would be appreciated as I had read a lot on the internet with no evidence outside this site including our customer:

  ttp://StackOverflow.com/questions/15396241/CX-Oracle-ora-01843-not-a-valid-month-with-Unicode-parameter h

  Thank you

  ...

  My question is, why the session loses the settings of NLS_DATE when it doesn't happen to anyone else? I think that the format is getting replaced in the sessions but how do I know that? How to find environmental changes to current public meetings?

  Maybe you have a connection pool if every session is used by different... hmm applications or threads. Even if you issue a command of nls alter at the start of the session, some processes could change this setting later. This is why it is best to not depend on any parameter of session happened when the connection was established.

  Best solution: just use the correct format inside the to_Char conversion. Or issue a command to alter session immediately before running the selection.

• ALTER session with ADF App statement

  Hello:
  
  11.1.2.3 Jdev
  RedHat 5.8
  Oracle db 11.2.0.3
  
  When you use a Web of Fusion ADF application, what are the consequences if we issue the command of database:
  
  ALTER session set time_zone = - 6; for a particular user
  
  For example, if the session is passivated? The database session remains with request on passivation module? or weblogic failover?
  
  Or will be session and users mix?
  
  Thank you very much.

  Hello

  you don't have a 1:1 data association in web applications. If you need to change the database to a user session you will have to do for each request, which means that you override the method of prepareSession AM ADF BC database alter session statement. So to answer your questions

  The database session remains with request on passivation module?

• ALTER SESSION in sql script produces strange results

  Why "alter session set NLS_DATE_FORMAT" would interfere with the operation of a sql script?
  
  First of all, 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 off

  And its execution:

  SQL> @doit1
  My Membership
  
  As of 14-JAN-10
  
    COUNT(*)
  ----------
   1

  Everything is 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 off

  And its performance
  

  SQL> @doit2
  set pagesize 99
  *
  ERROR at line 2:
  ORA-00922: missing or invalid option
  
  
  
    COUNT(*)

  You are missing just the leak ';' at the end of the line to alter session. Add to that, it all works.

• ALTER session in cfquery statement

  Hello world
  
  Would it not possible to use the alter session in a query?
  I would like to do something like this:
  < cfquery >
  ALTER SESSION SET NLS_COMP = LINGUISTIC;
  ALTER SESSION SET NLS_SORT = GENERIC_BASELETTER;
  Select geo_indication in the eccgis where country_fk = 'PT' and geo_indication like "% O";
  < / cfquery >
  As good in sqlDeveloper (oracle, without cfquery...), the application gives an error in CF (of semicolumns?).
  Did anyone get an idea?
  
  Thanks in advance,
  Michel

  Thank you very much.

  It is now fixed:
  The sort order also has implications on the SEARCH mechanism
  Looking for Oxxxxxx you can't find Óbidos
  and now:
  Search do not look upcase and focus more.

• ALTER session isn't wofking

  Hi all
  
  I created the process to edit the session to control the currency format, in any way the process works fine on the home page, but when you visit another page or return to the home page the session value (currency format) goes back to the previous setting ($). How can I keep this session fixed and consistent across my Web site?
  
  Also when I change the order of any report that the currency format will be shown in the older framework ($), I use the reports of PPR.
  
  PS, does not change when moving between pages of session state is same. Also, I tried the application process and process page on new session and the page load.
  
  Thank you
  Fadi.

  Try to add to the attribute VPD of your application (security settings):

  run immediately "alter session set nls_currency ="? "" ' ;

  .. .adjusted for what you really need.

  To clarify, it is an "equal" sign, followed by two single quotes consecutive, followed by a question mark where you can use the desired currency symbol, followed by three apostrophes, terminated by a semicolon.

• ORA-02248: invalid option for ALTER SESSION during the connection of the customer

  Hello
  I'm a junior dba and I was hoping if someone could help me with a problem I have. I recently installed on the oracle 10g client on my windows machine. I am trying to remote connect to my database on a unix machine, but I get error trying to connect from the client below.
  
  ERROR:
  ORA-00604: an error has occurred at the SQL level 1 recursive
  ORA-02248: invalid option for ALTER SESSION
  
  I did some searching on that and I think it might be something to do with the NLS_LANG setting maybe. I do not know if and to be honest, I'm a little lost on this.
  
  Any help would be greatly appreciated. See you soon.

• Query on ALTER SYSTEM SET

  
  Hello

  I was under the impression that

  To work around this limitation, Oracle has created the concept of the SPFILE initialization parameter can be changed dynamically using ALTER SYSTEM SET statement. »

  But, today, I started my test using PFILE database and run the following command to change the setting of the memory_target from 300 to 290 M.

  And to my surprise, this statement executed correctly without errors and memory_target parameter has been set to the new value (of course, in memory).

  Isn't it change the init dynamically using PFILE itself?

  Please clarify my doubt and correct my understanding.

  You have a bad mixing on the genesis of the SPFILE. Yes, it is a binary file and all this but remember, isn't the SPFILE which makes a dynamic parameter or a PFILE that makes static, but it is the nature of the setting itself which allows to happen. Yes, the difference in the PFILE and SPFILE parameter would be obvious when you change a dynamic parameter, and would give a rebound to the db. Since the PFILE file has not been updated (it's a text file must be updated manually), with the next restart, the setting would take the same value as it has in the PFILE file. But with the SPFILE, depending on what you have set in SCOPE, the parameter should behave accordingly.

• ALTER session privilege

  Hello
  Is there a reason why a developer may not have the privilege to alter session? My understanding of this privilege is that they will be able to make changes in only their own session, once they are disconnected the changes are cancelled. Is there any changes he could do in their own session that I (dba) will be wary of?
  
  Thank you.

  Thank you.

  Yes, your interpretation is correct that they are looged off the coast of changes back its session. But there are a number of reasons when ppl do not like to give developers alter session privilege.
  There are powerfully parameter during their session, developers can change like:

  
  sort_area_size
  optimizer_mode
  statistics_level
  optimizer_dynamic_sampling
  optimizer_use_pending_statistics
  optimizer_capture_sql_plan_baselines
  optimizer_use_sql_plan_baselines
  parallel_min_time_threshold
  parallel_degree_limit
  parallel_force_local
  optimizer_use_invisible_indexes
  parallel_min_percent
  cursor_sharing
  result_cache_mode
  parallel_instance_group
  hash_area_size
  result_cache_remote_expiration
  object_cache_optimal_size
  object_cache_max_size_percent 
  

  So if these parameter is changed into something weird that they can impact any database, specifically they can lower down the performance of the database and features.

  Best practice always review the requirements of developers and then after checking give privilege to alter session.

  Also check that the parameters can be modified using alter session

  Select the name of the parameter $ v where ISSES_MODIFIABLE = 'TRUE '.

  Hope this helps
