• I want to write a PL/SQL script to kill a session.

  I wrote a script for which considers a SID as input requests, V$ SESSION and verifies that the SID that you are trying to kill is not a background process, not SYS or SYSTEM and is the same user that you are. Once it checks these things, it issues an alter system kill session.
  
  If I create the SYS account service is very good. But I don't want end users to be able to run this script on the SYS account.
  I have another schema with privileges DBA I would love to own the PL/SQL script.
  
  Here's the rub, because the function queries session$ v, apparently not I can compile like no other function than to the SYS.
  If anyone can confirm this?
  
  I know that in PL/SQL, I can't access an object through a ROLE, I have been granted a SELECT on the object if I want to refer to it.
  But, if I'm in the SYS schema, I can't grant SELECT on v$ session to any account, because it's a dynamic performance view.
  
  Does anyone have a suggestion?
  
  Thank you

  I can't grant SELECT on v$ session to any account, because it's a dynamic performance view.

• 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.

• question about pl/sql script

  Hi all
  I need to manage other tables that will contain as follows:
  whenever the user query it will be an insert in this table called mng_rishui_session that contain
  track:
  NUM of user's session id,
  Date and time of execution of the request,
  type of query
  every 15 minutes, I need to delete the data of the user of some the various tables according to the type of the query.
  the tables that contain the data:
  mng_rishui_session / / DESC
  session_id_num NOT NULL VARCHAR2 (30)
  type_query not null number (2)
  date of time_query
  I want to write a pl/sql script like this:

   
  declare cursor c1 as 
  select session_id_num,type_query 
  from mng_rishui_session 
  where time_query (/*here i need to do the condition that 15 minutes has passed from the time query 
   i don't know how to do this */
  begin 
  for e in c1 loop 
  
  case e.type_query 
  when 1 
  delete query1_table where session_id_num :=e.session_id_num;
  when 3 
  delete query3_table where session_id_num :=e.session_id_num;
  end
  end loop;
  end;

  issues related to the:
  1. how to check if 15 minutes where the past
  2. it is good to do with loop for writing valid deletion in the loop
  or do I have to do it another way to write this.
  Thanks in advance

  Hi, Naama,

  end loop;
  end;
  

  first of all, I want to know where I'm going to do the validation, if I need to do.

  In the PL/SQL code (so we won't do it in case of error) but after the LOOP is finished.
  In other words, assuming you are using a LOOP. It will be much more effective if you just do a DELETE statement on each table. Think about it: If your mng_rishui_session has 1,000 rows where t_query (or time_query, if the column is always so called) is fortunate to have one of the type_queries you want at least 15 minutes, and 100 of these lines, then you must fetch the 1,000 rows (if not all of the table) , and separate 100 DELETE queries. It is more effective to extract 100 lines (assuming that there is an index composed of type_query and t_query) and to only 2 DELETE statements. See below.

  Second:
  I run this script through linux system, in order to head to sleep.
  My problem is that I am trying to append the output of script;
  but it won't let me

  People on this site will try to help you. Why not try to help them do it?
  Do not say "he won't let me": show all that you know the problem. What exactly have you tried? That's happened? If you got an error, display the full error message, including the line number. If you got the wrong results, describe what happened.

  My goal is:

  a script running the sql scripy called:
  CS-mng-session:

  #!bin/bash
  sqlplus user/passwd@dbname @mng_session /*mng_session is the script were i declare the cursor etc.*/
  in the command line i want to write :
  (sleep 600; sh cs-mng-session)& 
  

  the problem is that if I do not exit. He recorded in sql and the script does not return to the command line.
  How do I overcome this problem?

  Make an EXIT.

  Try something like this:

  DECLARE
       cutoff_date     DATE     := SYSDATE - (15 / (24 * 60));
  BEGIN
       DELETE     query1_table
       WHERE     session_id_num  IN (
                           SELECT  session_id_num
                           FROM     mng_rishui_session
                           WHERE     type_query     = 1
                           AND     t_query          <= cutoff_date
                         );
  
       DELETE     query3_table
       WHERE     session_id_num  IN (
                           SELECT  session_id_num
                           FROM     mng_rishui_session
                           WHERE     type_query     = 3
                           AND     t_query          <= cutoff_date
                         );
  
       COMMIT;          -- If desired
  END;
  /
  
  EXIT;
  

  Is there a reason why query1_table should be different from query3_table? Why can't you have just a query_table, with a column of type_query?

  What happens if there is an error? You won't want to know? You must add an EXCEPTION section to write the details about the error in a log table and someone send an email on this subject.

  In the above script as I must include conditions
  

  s.module in ('JSWPKSLIPN','OEXOEORD','ICPCKLOT','JSWPKSHIPHRM','JAINEORD') and
  s.last_call_et/1800 > 1
  and
  s.action like 'FRM%'
  and
  s.status='INACTIVE'

  So that the cursor c gets all the inactiive and serial No. session id and put loop and kills the session... ? He must check the two conditions and if any condition returns the lines, he should kill?

• What SQL script to use to configure the default TestStand tables?

  Hello

  I'm setting up a small test application and want to record the results of the test to a SQL Server database. Page in preparation for the implementation of logging database mentions the scripts I use to set my database. In my case, I found 3 table creation scripts:

  • SQL Server create insert generic result Tables.sql
  • SQL Server create Recordset result generic Tables.sql
  • SQL Server Create Tables.sql stored Proc result

  What are the differences between them, and which one should I use?

  Thank you!

  In the options dialog of database--> go to the patterns tab and click on each of the options (generic recordset, insert generics, etc.). In the comments section, you will find the difference.

  You can use one of them but to ensure that any script that you ran the DB tables same option is selected in the DB options.

  I hope this helps.

• How to run multiple parallel sql scripts?

  I try to execute multiple sql scripts parallel to the short run of the process via sqlplus. Are there opportunities to do? LINUX ORACLE 5. XX

  I do it too via Scheduler, but now I need to do this via sqlplus or shell + sqlplus?

  How do I start using shell script several xterminals and ech session begins all the sql scripts?

  nohup./SQL1.sh &

  nohup./sql2.sh &

  nohup./SQL3.sh &

  The '&' causes the script1.sh to run in the background so that the command prompt is returned immediately.  This means that sql2.sh can start immediately and at the same time as sql1.sh.  It doesn't have to wait for sql1.sh.   This assumes that there are no dependencies between scripts!  This meets your need to run scripts in parallel.

  The nohup untie your shell script.  So, even if you disconnect, the script continues to run.  Without the nohup, if you were to close your session before the end of the scripts running, they would get fired.

  Yes, we know what talking about your question.

  a .sql script is just a plain text file containing everything you want.  The code in it can be a pure SQL statements, it may contain of the PL/SQL code, and it can also include SQL * more specific orders (keep in mind SQL * more is a tool, not a language, so that these commands are specific to this tool and other tools which can also interpret the same commands).

  Not quite sure how your question relates to this blog, as this blog is showing the code that gets the data in JSON format in a jqGrid (jQuery grid?) and then exports the data in an Excel file.

  What you're trying to do is to take a series of SQL * Plus and SQL statements in a text file and generate a CSV file from them.

  As already mentioned, SPOOL is a SQL * more order, specific to SQL * more command line tool.  The database itself has no idea what "spool" means, while passing to the database somehow does not work.  I also doubt that netbeans knows what that means, either.

  So, in short, how you try to do, not you cannot.

• Running SQL scripts on different databases

  Hello!

  At my work we have many databases on a server. I have to make a request so that users can run the application on a selected database SQL scripts.

  So my question may be separated into 2 sections:

  1 - is possible to let users SQL scripts run directly from the application?

  I think a database to create a page that displays the list of all the SQL scripts, that we want to use, and when you click on a specific script name in the list, it asks something like "Where the database you want to run the script?", and then, as confirmed by the user, it would show results running the script on a different page.

  is 2 - possible to let users choose what database to run these scripts?

  Any information would be helpful, I'm at the beginning of the project and am not sure at all about how to proceed, or if it is at all possible.

  Thank you!

  Fallen_Kaede wrote:

  Thanks for the quick response. I confirm that we are talking about databases on a server.

  The request is to "debug" to other databases. For example, be run scripts to the locks on the list, to show the different indexes on a table, etc. to help diagnose problems.

  It looks like the 'users' are DBA who should use OEM/Grid Control to do so.

  1 - is possible to let users SQL scripts run directly from the application?

  Lol the only way to run scripts in the APEX is the use of the SQL Scripts for SQL workshop component.

  The key word in your question is 'application '. SQL * more and Developer SQL are applications that allow users to run SQL scripts on the desktop. Scripts SQL is an APEX integrated application that allows developers to run SQL scripts on the web. However, there is no documented way supported for end users to run SQL scripts in a custom of APEX application that you created. Therefore, rethink your approach. Rather than create an application APEX runs scripts, you must convert the scripts in PL/SQL, APEX packages, pages, components and applications leverage features of the APEX and reports, graphics and interactivity (e.g. exploration links; timed refreshes etc.). This will give you a user experience improved, beyond what is possible using static SQL scripts.

  is 2 - possible to let users choose what database to run these scripts?

  The APEX applications would exist on an instance of the APEX in a database and access other databases using the database links (which can have a performance impact). It would be possible to create a LOV based on the view of the USER_DB_LINKS dictionary and use in a selection set to a global page list to provide a control to set the current context of the database. Region data sources will have to be generated dynamically in the packages of PL/SQL use the links from relevant database based on this value LOV.

• 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:

  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.

• 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.

• executing sql script in ApplicationModule before processing a request

  Hello
  
  I have an obligation to run a sql script, just after the application module is read to process the request and before it actually processes the request.
  Basically, I View object in the AM based on a guaranteed table, that script allows the user to access the data in the table.
  
  Is there a particular method in ApplicationModuleImpl that I can replace to add the execution of the script. Or is there another way to do it.
  
  Thank you
  Anil

  Just replace prepareSession, it is executed each time an appmodule is associated with a user session. If you have just run the code on a specific VO, simply substitute the method executeQuery or executeQueryForCollection (in the VOImpl).
