SQl management studio provides lot of facilities to manage SQL processes. The “Activity monitor screen” which will show you some very useful and important information about SQL processes. It will show you all active processes, there status, number of open transactions for each process, the application by which the process is generated, Wait time CPU and memory utilisation, and the host name, means the host or the machine by which the process is initiated etc. If a process is hanging, it will show the process icon with an hour glass. Refresh it several times, sometimes the icon will turn to sleep mode if the process completes its execution. If the icon remains an hour glass, the process may be hanging. Use other info as well to decide if the process is really hanging. If you double click on the process ID it will show the SQL stamen subjected to the execution of the process. If a process is hanging you can identify which application has originated the process, which SQL stamen is hanging and even more from which machine or the host the process is initiated If some application users are complaining about uneven slowness, uneven timeouts etcetera, the reason behind may be one or more processors are hanging. What can you do now? You can restart the SQL server or the service which will disconnect all databases and all applications disturbing all the users. Or otherwise you can take the database to off line and bring it back to online. Or you can disconnect all connections to the database. The disturbance may be lesser than the previous case but still lot of applications and users can be disturbed, especially in an industrial setup. And still you do not know the real reason for the slowness or the malfunctioning as well. So what can you do? Go and examine the processors. Identify exactly which process is hanging. And most probably you will be identifying how and why. So you can find permanent solution. But the immediate solution is you can kill the troubling process or the few. It will solve the issue with minimum disturbance immediately. After identifying the correct process, you can right click on the process ID and click on ‘Kill process’ button. It will kill the selected process. You can kill processors using SQL statements and, using SQL commands you can kill all processors at once as well. Code for Killing Processes Individually USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' EXECUTE ('KILL 53') Code for killing all Processes USE master go DECLARE @dbname sysname SET @dbname = 'YourDB' DECLARE @spid int SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) WHILE @spid IS NOT NULL BEGIN EXECUTE ('KILL ' + @spid) SELECT @spid = min(spid) from master.dbo.sysprocesses where dbid = db_id(@dbname) AND spid @spid END

Killing Session live at peabody's opening for D.R.I

use master ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE --do you stuff here ALTER DATABASE YourDatabase SET MULTI_USER This video is about killing or disconnect all connections to a database. The easiest way is bringing the database to single user mode and set it back to multiuser mode. This will disconnect all connections form all the users other than current one who is logged to the database. One important aspect here is, do not close the screen once you set the database to single user mode. Because when a database is in single user mode it will allow only a single connection to the database. If you allow dropping your connection and if any other connects to the database you will not be able to connect the database again. So you may have to Stop the SQL server and start again to connect the database. It is also possible to do this using SQL management studio. Right click on the database, go to properties, go to options and move to restrict access option. There you can select the single user mode or multiple user mode. Now The question is why do you need to do this. I mean when, do you want to kill all connections. It is mainly, when you want to have exclusive access to the database. For example a database is not allowing you to restore a backup on this because you cannot grant the exclusive access, then you can bring the database to single user mode; killing all connections; perform your activates and after that set it to the multi user mode. This way you can maintain the exclusive access while you are completing the work.

The objective of this POC is to simulate the ability to check for idle database sessions and request user for approval to kill these idle sessions before they complain to the service desk.

In this tutorial you will learn how to monitor locks, latches, wait events in oracle.

This video demonstrates how to solve the ORA-01940 cannot drop a user that is currently connected error. This error is raised when we try to drop a user that is connected to the database or having an active connection to the database. We will demonstrate a solution in which we would kill the user that is connected to the oracle database by its serial# and PID. This tutorial will guide viewers on how to kill an active session and then drop the user.

https://amzn.to/2Ph2CbI [affiliate link] We are back again with some issues and solutions. Actually one of my friends asked me regarding performance tuning if forms are opening slow. That time I gave him some ideas and promised him that I will back very soon with some more information. There are lots of factors which may impact the applications but there are some work around which can helpful fixed the issues. One more thing I would like to tell, friends I shared my knowledge’s as per my real time experiences and real life experiences. So, there is not like just copying and pasting the stuff. As already I have shared my real life time stories which I have learned from my life. So, let’s start now. Suppose, our forms are opening slow then what things we should be check and how to debug it. I will try to explain here and share my knowledge. I am sure; it will be useful because it’s having been experienced. 1. We should check which forms are opening slowly either any particular form or all forms. 2. If all forms are opening slowly for particular machine then clear the cache and try again. It can be machine speed slow, machine hardware and bandwidth speed. If all forms are opening slow and for all machine then we really need to check below things such as: A. Check whether Trace is enabled or disabled and if it is enabled then kindly disabled it. B. Check the top commands if any resources are consuming high CPU usage. C. Check for all Inactive Sessions if it’s there then kill those sessions. D. Check for deadlocks. E. Every user should close the forms and logout properly. But actually we don’t care. We just close windows tab at a time and left for break :D :P but that’s also impact our EBS internally. F. A programmer if ran any program with infinite loops then this also cause a performance issue. That’s why we need to write any program carefully. If program not properly then it may cause deadlock as also which I have explained it in my previous posts. G. It can also be because of increasing the number of users. Also need to check users have one active session. H. Check for the Performance Pack (Native I/O) is turned on for WLS. And most and always we use this method. If the users have issue for any custom forms then we should follow below steps which are easy and very effective. When he run the program that time you should follow below steps: 1. Enable the Trace file. Login to front-end - Help - Diagnostics - Trace - "Trace with Binds and waits” . Then there will be a trace file generate under below patch: $cd $ORACLE_HOME/admin/$CONTEXT_NAME/udump Now you can run either Trace Analyzer or tkprof as shown below commands: Trace Analyzer command: $sqlplus apps/apps_password SQL START TRCANLZR.sql UDUMP ora-data_ora1919.trc; TKPROF command: $ORACLE_HOME/admin/$CONTEXT_NAME/udump $tkprof ora-data_ora_1919.trc ora-data_ora_1919.txt explain=apps/apps_pwd Hope this may useful and helpful. We will come back again with new troubleshooting and solution as what we should do if forms opening slow after increasing the number of session. For any concerns or suggestions please reach to us either by comment box or contact us @ ora-data.blogspot.com.

#Oracle #V$Views Querying V$ performance views

Instructions fro Liberty Auditor to kill Sessions in Client Server

Why I Need To Know. Have you have ever needed to know or wanted to know how to identify an Oracle client process and its associated foreground process from outside of Oracle, at the operating system? And, prompt using a command like "ps"? In this video tutorial, I'll show you how to do this using the super flexible OS "ps" command. It's very cool and is the first step to relating what we see from an internal Oracle perspective using V$ views to what we see from an OS perspective using a command like "ps.” Founder and Oracle ACE Director, Craig Shallahamer, is a long time Oracle DBA who specializes in Oracle performance. He is a performance researcher and blogger, consultant, conference speaker, and a teacher to Oracle professionals.

User-defined functions in SQL Server are very much like custom methods and properties in .Net languages. At first sight, they seem to be the perfect tool to introduce code encapsulation and reuse in T-SQL. So why is this feature mostly avoided by all T-SQL gurus? The reason is performance. In this session, you will learn how user-defined functions feed the optimizer with misleading and insufficient information, how the optimizer fails to use even what little information it has, and how this can lead to shocking query performance. However, you will also see that there is a way to avoid the problems. One type of user-defined function, the inline table-valued type, may not be the easiest to use, but it is the only type of user-defined function that doesn’t impact performance. I will show how, with just a little extra effort, you can reap the benefits of code encapsulation and reuse without sacrificing performance.

Typically, malicious users target the inactive sessions to gain access into the database. By reducing the period of time an inactive session stays connected, the probability of that session being a victim of abuse is reduced. Also, setting up idle_time helps to reduce problems of having too many INACTIVE sessions.

How to lock and unlock a user account in an Oracle database

How to Create an user in Oracle with minimum grants/privileges we need to connect as SYSDBA lets ceate an user test you can see the user is created : But can it connect? lets open a new session we can see it lacks create session priv. so, we grant the create session privilege to user test lets test Its connecting. But is it able to create a table ,lets check. it lacks the ability to create table. SO lets give the privilege. lets test again the create table command. its throwing error regarding no Privilege on users tablespace . But we have given USERS as the default tablespace to test(user). So whats the problem? The problem is there is not quota defined for user test. lets give some quota like "10MB" or UNLIMITED , we will giev 10MB NOw let us test. So we can see that we now have sufficient / minimum privileges for the user test. Hope this will help in understanding the concept behind user creation
