How do you manage exceptions / errors in stored procedures?
How do you manage exceptions / errors in stored procedures?Exceptions/errors can be handled in different ways in the stored procedures.
(1) could be using an EXCEPTION block in the procedure in which to use WHEN
(2) may declare a variable in the DECLARE section as EXCEPTION type,
raise it to the extent necessary using STIMULUS and manipulate in EXCEPTIONAL setting using the WHEN clause.
(3) could use keywords SQLCODE & SQLERRM to display no errors and the error code...

How can you correct 0x8dddooo4 error message
How can you correct 0x8dddooo4 error message
What's next for security/antivirus installed; is it's subscription and current definitions; has whatever it be detected by it when the system was analyzed last?
Malware does not reside on the system or you need to read this Microsoft KB article:
Error that you see in the upper right when you visit the Windows Update Web site on a Windows XP-based computer: "[error number: 0x8DDD0004]."All the steps in the above article can be made by downloading, recording, then by running the Fixit of: How to reset the Windows Update components?
Once the download is complete, close all open programs and web browsers.
Then, run MicrosoftFixit50202.msi and choose it is the default mode.The default mode performs the same steps as shown in the article first, KB914224 and that someone at Microsoft should edit this page so that it refers to the Fixit.
Please note that if the malware resides on the system, then the components of Windows may updates reset / will fail or just temporarily fix the error code, what malware is.

How do you manage file types in windows 7?
How do you manage file types in windows 7? There was a tab for it under XP folder options. If I can't solve the problem I will downgrade to xp and back to windows 7.
Tab file types has been removed in Windows Vista & Windows 7 and replaced by "default programs". If you need to customize the type of file to a higher level associations (for example, the addition or the change of a supplementary verb in a class file), you need to maybe use a third-party tool or change the registry manually.
If you have a specific requirement, pls after return.

I invoke PurchaseOrderService, Version 2, as part of the Rel9. I use wss_username_token_over_ssl_client_policy security policy.
How do you manage the Username and the password?
Here is a code snippet:
SecurityPolicyFeature[] securityFeature = new SecurityPolicyFeature[] { new SecurityPolicyFeature("oracle/wss_username_token_over_ssl_client_policy") }; purchaseOrderService_Service = new PurchaseOrderService_Service(); PurchaseOrderService purchaseOrderService = purchaseOrderService_Service.getPurchaseOrderServiceSoapHttpPort(securityFeature); WSBindingProvider wsbp = (WSBindingProvider)purchaseOrderService; wsbp.getRequestContext().put(WSBindingProvider.ENDPOINT_ADDRESS_PROPERTY, "https://prc-XXXXXXXX.oracleoutsourcing.com/prcPoEditDocumentOrder/PurchaseOrderServiceV2"); wsbp.getRequestContext().put(WSBindingProvider.USERNAME_PROPERTY, "myUsername"); wsbp.getRequestContext().put(WSBindingProvider.PASSWORD_PROPERTY, "myPassword");
This doesn't seem to be a very safe way to manage the usernames and passwords.
What is best practice?
Thank you

How do you manage the global permissions?
As a global organization our counterparts around the world ask access features in Eloqua. What worries me, is their willingness to create landing pages and emails with no programming experience. We offer flexibility to our partners, but we find that we have often to recreate what they have planned. In the end, it's more work on our end. How do you encourage the use of the tool, while at the same time discouraging programming assets?
OK - So - here is an interesting idea, at least for emails (not not landing pages).
And if you allow them to create their own emails, but makes them do to engage? So, you create and manage models... who now may have locked for editing components. (Regular e-mail in E10 generator cannot do yet to my knowledge). They can just update their copy. You can pull the code from the source to deliver, implement E10 email to send then it will hopefully not be all jacked.
Or, if you're willing to give them more flexibility, you can give them a template gallery and beg and plead and say, then they will be in trouble with [executive name with influence here] if they do something outside of the model. Unfortunately you cannot help but change the model however they want it immediately, but if you give them changes pretty much - different models and configurations for different types of campaigns - in most cases they should be able to find something that works, right?
I'm sure you have already thought about this... it is a difficult question. You can implement all of the desired governance, but people get to change their habits which is the hard part, especially if you don't have the appropriate level of support to help you grow.

5477 / 2 - tas-possible... How did you manage it?
Im sure everyone has figured out what to do with this signature. It fires a lot because of the (gun ad) code used on some high traffic as lanebryant sites.
Intelli shield recommends that filter us servers Web page hosting web non-ASCII.
How am I supposed to know what Web servers host web pages not ASCII? How can you filter this? I do not disable this sig, because it represents an achievement of high risk, but many false positives... What have you done with 5477-2?
Description of 5477 / 2:
This signature is triggered on detection of unicode escape sequences encoded in HTML pages. It is a common way to load the values in memory and is frequently used in the buffer overflow exploits. While the use of unescape() indicates that anything malicious happened, in addition to investigation may be warranted. This signature is also a component of META signature 5556-4.
Recommended filters
Filter servers Web page hosting web non-ASCII.
Benign triggers
Benign triggers have been identified with HTML pages represented in non-ASCII characters.
Thank you very much
I tried replying earlier, do not know if it will do ;-) This made signature part of a META signature 5556-4, eliminating the action prevent to draw on its own (we have disabled for a long time due to the high rate of false positives). If you disable / give up to use it, you need to address 5556-4 as well.

Trapping errors in stored procedures
I run queries on a Government computer. There are errors in some of the stored procedures that will NEVER disappear. Reality of life and I have to live with it (I'm just a data analyst - not the developer of procedures)
If I do this, hoping to catch the error
Well, he can still plant.BEGIN run_stored_proc (my_cursor, my_id, param3); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE ('ERROR IN ID (' || my_id || '). The error was ' || SQLCODE || ' -ERROR- ' ||SQLERRM); END;
So, it seems that run_stored_proc calls some_other_stored_procedure, which has problems. I was hoping to trying to capture the error in the procedure at a higher level, it would also seize the error at a lower level 'Sub procedure. It is how works a TRY-CATCH in java. If an error occurs anywhere along the path inside the TRY-CATCH, she is caught. Of course, java ins't of PL/SQL, but is it possible for me to catch a lower level error and do not have this code crash?SQL> @c:\mysql\run_test ERROR IN ID (2692). The error was -20100 -ERROR- ORA-20100: Exception occurred in some_other_stored_procedure ORA-01422: exact fetch returns more than requested number of rows
Fortunately for me, it actually does not crash as often. But I have to put this code in a loop, then run it to many different my_id. And when he plant, it is not important from a data analysis perspective. I can't do without a small percentage of the data. But I'd love to be able to just run my script and do not have to look for unexpected accidents.
This isn't a question about how to solve the error too many lines in the procedure. I don't have access to the procedure, and it's not going to be fixed. I just need to know how to deal with the capture of the error, if it is at all possible.I'm not sure I Armi what you're asking here. Your script is not 'crash', it is just to report the error through the dbms_output.put_line statement you added. When you say "I have to put this code in a loop, then run it to many different my_id", do you mean you want to call run_stored_proc multiple times with different values of my_id?
If so, then it should look like:
begin for rec in (select my_id from wherever) loop BEGIN run_stored_proc (my_cursor, my_id, param3); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE ('ERROR IN ID (' || my_id || '). The error was ' || SQLCODE || ' -ERROR- ' ||SQLERRM); END; end loop; end;
The other Manager to swallow the error and control will return at the top of the loop statement and execute the procedure with the next value of my_id.

How to migrate from MySQL to Oracle stored procedure
Hi all
I've migrated mysql 5.1.42 - enterprise-gpl-advanced DB for oracle sqldeveloper 3.1.07 tool.
DB objects migrate successfully except stored procedures.
I checked .sql and files... Capture process not captured SQL stored procedures.
Could you please suggest where I can check correct error or how to fix this.
Thanks in advance.
Hello
SQL * Developer version you use is an old and you must use the latest version available from this link.
However, even the v4 version does not support the migration of procedures stored as stated in this link - MySQL
http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/supportedmigplatforms-086703.html
You will need to manually convert the MySQL in Oracle format, stored procedures since even the "Scratch Editor" under "tools - migration '-doesn't have an option for MySQL conversion.
The documentation includes details of the difference between MySQL and Oracle stored procedures-
Oracle SQL Developer information for the migration of MySQL®
in chapter Triggers and procedures stored

How to convert MS SQL Server 2008 Stored Procedures of Oracle 11 g SPs?
We have an application from MS SQL Server 2008. We want to migrate to Oracle 11 g.
What is the recommended Oracle method for
(1) migration of data (Tables, triggers, sequences, views etc..)
(2) the stored Procedure migration.
What is the recommended tool or method pls?
We have 100s of MS Sql Server stored procedures. Then, needing a tool or method. We can rewrite all of them from scratch.Hello
Let me clarify some of the issues that you mention. But I advise you to get some professional help with migration because:
1. you must understand the architectural differences between SQL Server and Oracle. They are of different databases.
2. understand data type mappings.
3. understand the complete migration process. Just using the OTN article as a migration guide won't help because it just shows how use SQL Developer to this task.
4. understand that 100% of successful Oracle conversion is not possible with all the tools. There will always be gaps, gaps in functionality, bugs etc. So there will be some amount of manual work involved.
5. There are many other tasks involved in the migration that cannot be accomplished with SQL Developer.Get now your questions:
1. in 3.1, there is migration option for the "capture of database in offline mode". It is under the Tools option. So in 3.1 we do not have a separate tab, called "Migration."
2. use 3.1 because it is much better than 2.1 in terms of capabilities.
3 migration Wizard is the easiest way to migrate. Where are you getting confused?
4 "column data" seems to be a stored procedure in SQL Server. If it is not there in the underlying table, why he uses in the SQL statement in the procedure then? I think that we have a problem of "reserved word" with the name of column "Data". Will have to check that.
5 VARCHAR (@max) must be mapped to VARCHAR2 (4000) in Oracle. It may be a bug in SQL Developer. So during the mapping of data type in the migration wizard, you can change the default mappings.Concerning
