• '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?

• 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

  First of all, I've noticed this with a 10.2.0.1 connected to a 10.2.0.4 (windows) client database (HP - UX). Confirmed on my laboratory portable VM, 10.2.0.4 under OEL5, client and db on the same virtual machine.

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

• ALTER session set current_schema

  Hello

  We have multiple instances of the database (for example, MR01DEP, MR02DEP,...).

  Each instance is composed of more than stores (called schemas): for example, for MR01DEP, we have STORE1, Bank 2, 3, to MR02DEP we STORE5, STORE6,... and so on.

  Now, using developer PL/SQL, SQL Developer or even SQL Plus, when I connect to these databases, I connect using the user SUP_TMP (who has the privileges necessary for the actions that I have to do), and I have something like this:

  Conn SUP_TMP / < password > @STORE1 (I can connect like this and not with @MR01DEP; However, even @MR01DEP is correct).

  Today, all the tables are on these patterns (STORE1, STORE2,..), and when I connect with the SUP_TMP user, each time, at each meeting, I have to write:

  ALTER session set current_schema = STORE1, or

  ALTER session set current_schema = Bank 1

  At the beginning of every script that I have to run, I want to write a little routine so that I don't need every time to this «alter session set current_schema» statement

  If I connect with SUP_TMP / < password > @STORE1.

  so I see in the instance of v$, as the instance_name is (correct) MR01DEP.

  But I need to somehow get that banks '1', which I use when I connect to it (although, normally, I connect to a database, such as MR01DEP, but I'm specifying STORE1 in the connection string).

  So, in other words, I need that at the beginning of each script, to determine the current connection string I'm specifying after '@', and which is the current_schema.

  If I log in as SUP_TMP / < password > @STORE5, then I'll have something like immediate execution "alter session set current_schema = STORE5'."

  SUP_TMP user should be the I connect each time, but the current pattern of each script in each session, must come from the connection string.

  Is this possible?

  Thank you!

  I know, I specify the store, and it will automatically connect to the correct database (this is the case).

  No - NOT sure that connect you to the right base.

  As said ground that alias 'keep' is on the client and can be mapped to ANY DATABASE at all.

  Also - what you specify with is the DATABASE - this isn't a pattern.

  You're talking about two different things.

  You set the current schema - you connect to a database. TWO DIFFERENT THINGS.

  It may not even be a schema with the same name as the database.

  Do not use the same name for the databases and schemas. Oracle is NOT sql server.

  You can create a trigger AFTER the opening of SESSION to define the schema for you, but you must be able to know which schema must be defined.

  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

• session is not killed properly

  I use oracle 10g (10.2.0.1) in Redhat Ent Linux 5.0.

  In my production database, one of my session which is connected thorugh 'TOAD' program is hanged.

  I kill this session several times but not removed from the session and it shows the status is 'DEAD '.

  Here is the result:

  SQL > select username sid, serial #, session state $ v where status = 'KILLED ';

  USERNAME SID SERIAL # STATUS

  ------------------------------ ---------- ---------- --------

  1860 37381 KILLED DBPROD

  SQL > alter system kill session '1860,37381';

  alter system kill session ' 1860,37381'

  *

  ERROR on line 1:

  ORA-00031: session marked for kill

  SQL > alter system kill session '1860,37381' immediate;

  alter system kill session '1860,37381' immediate

  *

  ERROR on line 1:

  ORA-00031: session marked for kill

  Also during the session to kill, there is no show message in the log file of the alerts associated with the kill command.

  Now, please help me how I can fix this without closing the database.

  EDIT the SYSTEM KILL SESSION does not remove the session.  The session dies only when the user actually tries another SQL operation and is thrown a mistake - that is to say when Oracle kills the process.

  The other option is to use an OS command to kill the server process - but you need to know how to do this and identify the right process to kill (assuming not shared server and dedicated server connections).

• 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

• 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.

• 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.

• TV Guide will not retain the local settings. There is no user.js file. How can I fix it?

  TV Guide will not retain the local settings. After that the closure of the site reverts to the default settings. There is no user.js file. Delete the prefs.js file did not help. Any suggestions?

• Microsoft windows media player does not retain the previous size. is irrtating so me gift of reorganize its size every time when I open it.plz help I want stable wmp version 11

  Microsoft windows media player does not retain the previous size. is irrtating so me gift of reorganize its size every time when I open it.plz help I want stable wmp version 11, version 12 is sucks.

  Hello, Simone

  I'll assume you're on Windows 7. Windows Media Player 12 is not supported on Windows Vista or XP and as such, you will need to go back to Windows Media Player 11.

  You can check the permissions in the registry to ensure that it is able to record information.

  Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.

  Open the registry editor by clicking on start, type regedit.exe in the search box and press on enter, you may be prompted to continue.

  In the registry editor, navigate to HKEY_CURRENT_USER, Software, Microsoft, MediaPlayer, then Preferences.

  It should be an element named LastLocation_26, right-click on it and select Rename, and rename it to old LastLocation_26.

  Leave the open registry editor and open Media Player, then move it to your favorite place and close Media Player.

  In the registry editor, press F5 on your keyboard and check if LastLocation_26 has been recreated.

  If this is not the case, there is probably a permissions problem.

  If so, the location must be registered.

  Let us know.

• When I try to send an email to MYOB I get error message saying: "an email session could not be started. Please check your MAPI installation '.

  Error message: a message session could not be started. Please check your MAPI installation - sending email from MYOB

  When I try to send an email to MYOB I get error message saying: "an email session could not be started. Please check your MAPI installation '.

  How can I solve this problem?

  Hi all

  I have a workaround which is a little less boring that the patch "restart the PC": If you get the error where MYOB crashes when you try to send an e-mail, open Task Manager (ctrl-alt-del or right click on the start bar), then go to the "Processes" tab and close all instances of wlmail.exe using the button "complete the process".

  It seems that this error occurs if you have Windows Live Mail opened when you try and send emails of MYOB. If you then close WLMail after that get the error the process seems to never close, so you have to close it manually. If you send all your emails with closed WLMail MYOB it seems to be OK.

• WRT600N - Wireless MAC Filter Table will not retain MAC for the Droid 2 phones

  Hello

  I have a Linksys WRT600N router and I succumbed adding our new Motorola Droid 2 to the MAC table on the Wireless Security tab.

  It allows access if I disable MAC filtering wireless and appears on the list of clients, but when I try to add the customer list or manually enter the MAC table, it does not retain it when I save it. The only thing that seems different from the MAC standard is the 1 byte

  (F8:7 B: 7 A: 76:98:22 is the MAC of my phone).

  I don't want to leave my network open and prefer to avoid using a WEP key if possible.

  Can anyone tell me what I am doing wrong or is this a bug? Y at - it a firmware update I have to apply to this effect in my MAC filter (current version is 1.01.36 build 3)?

  Oh and I'm not worried about hackers if as much as deterrence of neighbors stealing my bandwidth. To implement the keys on all my devices was too much time to consider unless a last resort. MAC filters make it also easier for me to add guests fairly quickly.
