6. Always log error (and backtrace) before re-raising the exception.
 
02:28
When you re-raise an exception, you will reset the backtrace (the track back to the line on which the error was raised) and might change the error code (if you raise a different exception to propagate the exception "upwards"). So it is extremely important to call you error logging subprogram (see previous Good to Know) before you re-raise an exception.

8. Use LOG ERRORS to suppress SQL errors at the row level.
 
06:23
The impact of a non-query DML statement is usually "all or nothing". If my update statement identifies 100 rows to change, then either all 100 rows are changed or none are. And none might be the outcome if, say, an error occurs on just one of the rows (value too large to fit in column, NULL value for non-NULL column, etc.). But if you have a situation in which you would really like to "preserve" as many of those row-level changes as possible, you can add the LOG ERRORS clause to your DML statement. Then, if any row changes raise an error, that information is written to your error log table, and processing continues. IMPORTANT: if you use LOG ERRORS, you must must must check that error log table immediately after the DML statement completes. You should also enhance the default error log table.

5. Capture call stack, error code, error stack, error backtrace.
 
05:59
Ideally, this is a total non-issue for you, because you simply invoke a generic logger procedure in your exception handlers (example and recommendation: download and use Logger, an open source utility that does almost anything and everything you can think of). But if you are about to write your own (or are using a home-grown logging utility), make sure that you cal and store in your log (likely a relational table), the values returned by: SQLCODE DBMS_UTILITY.FORMAT_CALL_STACK (or corresponding subprograms in 12.1's UTL_CALL_STACK package) - answers question "How did I get here?" DBMS_UTILITY.FORMAT_ERROR_STACK (or corresponding subprograms in 12.1's UTL_CALL_STACK package) - answers question "What is my error message/stack?" We recommend using this instead of SQLERRM. DBMS_UTILITY.FORMAT_ERROR_BACKTRACE (or corresponding subprograms in 12.1's UTL_CALL_STACK package) - answers question "On what line was the error raised?"

Oracle Troubleshooting Guide
 
09:44
https://ora-data.blogspot.in/2017/07/oracle-troubleshooting-tips.html Oracle DBA troubleshooting is very important and advance for DBA’s life. We all should know and understand the troubleshooting ways. Here we have some points and the ways which can be helpful in troubleshooting. One thing I would like to share here that troubleshooting is not a rocket science but people make it like a rocket science hehehh. Even if rocket science also we can do it friends. Friends, please just try once and follows these below points. I am sure it will be very useful. There are many more points technical but I tried to explain in very simple ways to kick start. As per my experiences I have seen some people feel as troubleshooting is either hard or they afraid. WHY TROUBLESHOOTING IS HARD: 1. You feel as you can’t do it even without any try. Already they have mindset. 2. You think it will take time but it takes time for everyone. You know one SECRET, no one know everything, even seniors also check in metalink or google. Only one thing is different i.e. Observations as per experiences. Otherwise everything is same. Whatever we/they do, you can also do. 3. You afraid about mistakes but we need to try on test server which everyone does it. Never give up. Today if you try for 1 hr and got solution, tomorrow you will be king of it. If you do not get solution in 1 hr, take it as challenge and try till get the solution. Every one learns like this only. Simple Steps to START TROUBLESHOOTING: 1. You must Read error carefully. 2. Must check alert logs accordingly. 3. Check for related error either in Metalink or Google. 4. Understand or observe the error 100%. Do not be hurry in investigations. After checking Metalink or Google, never do hurry to execute solution. First understand the solution 100% thoroughly. Check what is required in the given solution. Some Important Suggestions: For Example: Suppose, there is given any “rm” command in solution. As per my DBA experiences never ever use “rm or rm –rf” command. If required check 7 times before using this command. Actually I forget this command; I don’t know “rm or rm-rf” command hehehh. If it is very necessary, then take the backup of file and then remove. Before executing solution check for any SQL DML command or any other SQL SCRIPTS statements which can impact like DML or any Transactional etc… And if you are not sure then check on test servers and check with your seniors. I guarantee that just follow these simple above steps. You will see yourself changes. If any more suggestions, I will keep update here. And also if you have any more points please let us know which will be helpful for all of us.

Top Nine Coding Guidelines for Oracle PL/SQL
 
08:00
My take, as of November 2015, of some of the most helpful guidelines to follow when writing PL/SQL code: 1. MAXSQL - maximize use of SQL first and foremost 2. SPOD - single point of definition 3. TRACE - production-available application-level tracing 4. LOG - consistent, encapsulated error logging 5. BULK - avoid row by row 6. OBVIOUS - make your code tell its own story, comment when it can't 7. NESTPROG - use nested subprograms 8. DECLARE - use declarative features of language 9. WARN - use compile-time warnings Accompanying blog post: http://stevenfeuersteinonplsql.blogspot.com/2015/10/your-ideas-for-more-important-plsql.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

Debugging sql server stored procedures
 
15:11
debugging in ssms debugging t-sql code t sql debug stored procedure sql server management studio debug stored procedure how to debug t sql debug in sql server management studio In this video we will discuss how to debug stored procedures in SQL Server. Setting up the Debugger in SSMS : If you have connected to SQL Server using (local) or . (period), and when you start the debugger you will get the following error Unable to start T-SQL Debugging. Could not connect to computer. To fix this error, use the computer name to connect to the SQL Server instead of using (local) or . For the examples in this video we will be using the following stored procedure. Create procedure spPrintEvenNumbers @Target int as Begin Declare @StartNumber int Set @StartNumber = 1 while(@StartNumber [ @Target) Begin If(@StartNumber%2 = 0) Begin Print @StartNumber End Set @StartNumber = @StartNumber + 1 End Print 'Finished printing even numbers till ' + RTRIM(@Target) End Connect to SQL Server using your computer name, and then execute the above code to create the stored procedure. At this point, open a New Query window. Copy and paste the following T-SQL code to execute the stored procedure. DECLARE @TargetNumber INT SET @TargetNumber = 10 EXECUTE spPrintEvenNumbers @TargetNumber Print 'Done' Starting the Debugger in SSMS : There are 2 ways to start the debugger 1. In SSMS, click on the Debug Menu and select Start Debugging 2. Use the keyboard shortcut ALT + F5 At this point you should have the debugger running. The line that is about to be executed is marked with an yellow arrow Step Over, Step into and Step Out in SSMS : You can find the keyboard shortcuts in the Debug menu in SSMS. Let us understand what Step Over, Step into and Step Out does when debugging the following piece of code 1. There is no difference when you STEP INTO (F11) or STEP OVER (F10) the code on LINE 2 2. On LINE 3, we are calling a Stored Procedure. On this statement if we press F10 (STEP OVER), it won't give us the opportunity to debug the stored procedure code. To be able to debug the stored procedure code you will have to STEP INTO it by pressing F11. 3. If the debugger is in the stored procedure, and you don't want to debug line by line with in that stored procedure, you can STEP OUT of it by pressing SHIFT + F11. When you do this, the debugger completes the execution of the stored procedure and waits on the next line in the main query, i.e on LINE 4 in this example. To stop debugging : There are 2 ways to stop debugging 1. In SSMS, click on the Debug Menu and select Stop Debugging 2. Use the keyboard shortcut SHIFT + F5 Show Next Statement shows the next statement that the debugger is about to execute. Run to Cursor command executes all the statements in a batch up to the current cursor position Locals Window in SSMS : Displays the current values of variables and parameters If you cannot see the locals window or if you have closed it and if you want to open it, you can do so using the following menu option. Locals window is only available if you are in DEBUG mode. Watch Window in SSMS : Just like Locals window, Watch window is used to watch the values of variables. You can add and remove variables from the watch window. To add a variable to the Watch Window, right click on the variable and select "Add Watch" option from the context menu. Call Stack Window in SSMS : Allows you to navigate up and down the call stack to see what values your application is storing at different levels. It's an invaluable tool for determining why your code is doing what it's doing. Immediate Window in SSMS : Very helpful during debugging to evaluate expressions, and print variable values. To clear immediate window type ]cls and press enter. Breakpoints in SSMS : There are 2 ways to set a breakpoint in SSMS. 1. By clicking on the grey margin on the left hand side in SSMS (to remove click again) 2. By pressing F9 (to remove press F9 again) Enable, Disable or Delete all breakpoints : There are 2 ways to Enable, Disable or Delete all breakpoints 1. From the Debug menu 2. From the Breakpoints window. To view Breakpoints window select Debug =] Windows =] Breakpoints or use the keyboard shortcut ALT + CTRL + B Conditional Breakpoint : Conditional Breakpoints are hit only when the specified condition is met. These are extremely useful when you have some kind of a loop and you want to break, only when the loop variable has a specific value (For example loop varible = 100). How to set a conditional break point in SSMS : 1. Right click on the Breakpoint and select Condition from the context menu 2. In the Breakpoint window specify the condition Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures_28.html

Working with the Trace File Analyzer Collector
 
28:22
The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command. Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface Copyright © 2014 Oracle and/or its affiliates.

ADF Tutorial - ADF Logging - Part 1
 
10:24
This tutorial covers overview of ADF Logger and steps to configure it in JDeveloper. • ADF Logger is a debugging mechanism that will help diagnose various errors in an ADF Application. • It consists of various debugging tools written around the API ADFLogger to be used in both JDeveloper and the WebLogic Enterprise Manager. • ADFLogger is a wrapper utility developed on top of java.util.Logging with added convenience methods. • You can still use other logging mechanisms such as Log4J, Commons Logging, SLF4J, etc. However, ADFLogger has been seamlessly embedded into ADF Framework so that you do not need to reinvent the wheel. • ADF Logger along with Oracle Diagnostic Log Analyzer will not only provide you logging mechanism for your custom code but also give you the flexibility to go trace through all the JSF Page Lifecycle and BC4J events.

How To Use The Oracle SQL Net Message To Your Advantage - Introduction
 
01:27
How To Use The SQL*Net Message From Client Event To Your Advantage - webinar introduction. Idle wait events are usually ignored in our performance analysis. It's because they diminish what we should be focus on... most of the time. We need master the "not most of the time" as well. So, in this webinar I'm going to focus on the idle wait event, SQL*Net message from client. I'll show you what this wait event is, why it's important and not important, and how to use it to our advantage in both a time-based analysis and an ASH based analysis. And of course, you'll be able to download and immediately use any tools that I use. For more information on how you can watch the full length webinar, or for more information on Oracle Ace Craig Shallahamer, go to www.orapub.com
