• How to catch exceptions in PowerCLI when the cmdlet PowerCLI

  Hello

  I count just one problem when catch exception throw by powercli cmdlet.

  I use the 'trap' to catch the exception like below:

  -

  ---

  Get-VMhost 192.168.43.110

  Trap {}

  "Exception when get-vmhost.

  }

  -

  ---

  I want to do this: when the 192.168.43.110 host did not exist or can not connect, I have to catch the error and give a friendly advice!

  but unfortunately the code in the block 'trap' has not run, and the error message will appear:

  -

  ---

  Get-VMHost: 2010-11-29 15:20:14 VMHost Get-VMHost with the name "192.168."

  .43.110' not found, using the specified filters.

  On line: 1 char: 11

  + Get-VMHost < < < < 192.168.43.110

  + CategoryInfo: ObjectNotFound: ( , VimException)

  + FullyQualifiedErrorId: Core_OutputHelper_WriteNotFoundError, VMware.VimA

  utomation.ViCore.Cmdlets.Commands.GetVMHost

  -

  Your idea will be a great help for me!

  Thanks in advance!

  Hello

  The reason you're trap code is not executed because the trap block intercepts only the errors, but the error you get is non-terminating. You can set the world

  $ErrorActionPreference = "Stop"
  

  or the cmdlet the ErrorAction parameter:

  Get-VMhost 192.168.43.110 -ErrorAction:Stop
  trap {
  "Exception when get-vmhost"
  }
  

  You can take a look at this thread Re: how to catch the VimExceptions correctly? also

• How to validate SQL syntax in Application Engine Peoplecode

  Hello
  
  Can someone help me to find out How to validate SQL in Application Engine Peoplecode. I just need to validate SQL syntax. If the syntax is wrong, it should save the exception in the log file but engine Apllication should not go WITHOUT success. App Engine should continue with other SQL validation to check the correct syntax and to retrieve values.
  
  Here is given is peoplecode, which is that I currently use.
  
  Thanks in advance.
  
  
  String local CSG_SQL_ID & sqltext;
  Local date & effdt;
  Local Boolean & sql_flag = True;
  
  & CSG_SQL_ID = CSG_REP_DIS_AET. CSG_SQL_ID. value;
  SQLExec ("SELECT DEV. CST PS_CSG_SQL_TMP, CRAD PS_CSG_REP_AUT_DST SQLTEXT WHERE CSE. CSG_SQL_ID = DEV. CSG_SQL_ID AND CST. EFFDT = DEV. EFFDT AND CST. CSG_SQL_ID =: 1 ", CSG_SQL_ID, & sqltext);
  
  Try
  
  & sql_flag = SQLExec (& sqltext);
  If & sql_flag = True Then
  & sql = CreateSQL (& sqltext);
  Local string SqlString = & sql. Value;
  Logger (String (ExtractTablesJob (& SqlString)));
  Logger (String (ExtractTablesDept (& SqlString)));
  End - If;
  
  catch Exception & sqlerror
  MessageBox (0, "", 0, 0, "found Exception");
  end - try;

  Ludi,

  I apologize: I remembered wrong. The Select Type must be reselect. I opened a ticket with Oracle on this problem. I hope that maybe they will build better error messaging tools, but we'll see. The real result of the ticket, it is that evolution to select Type of reselect solved my problem.

  Remember that when you Reselect it, you need to follow wherever you are. Reselect him running the DoSelect SQL statement every time until it returns no rows. So, you will need a flag turned on the table. You're DoSelect should select only the rows where the transformed flag is N. Then, you must update the line you are dealing with to set the flag turned on Y. In this way, you will pass through the processing of each lines.

  Also, just to be clear, I don't think that App Designer will ever "validate" your SQL. It allows the database to do that when you run it. It can be frustrating because up to now it is not telling you that you are developing, but the advantage is that App Designer does not limit you. You can place some SQL you want in your program, and it will transmit to the database. Stored procedures, functions, all work because the App Designer do not validate things specific special platform.

  If you wish, you can copy your SQL in the SQLExec to a SQL definition:
  SELECT THE DEV. SQLTEXT
  OF PS_CSG_SQL_TMP CST.
  PS_CSG_REP_AUT_DST SLAG
  WHERE CSE. CSG_SQL_ID = DEV. CSG_SQL_ID
  AND CSE. EFFDT = DEV. EFFDT
  AND CSE. CSG_SQL_ID =: 1

  You could name MY_AE_SQL.

  Then, in your App Engine PeopleCode, you can change the SQLExec in:
  SQLExec (SQL. MY_AE_SQL, & CSG_SQL_ID, & sqltext);

  This will place your SQL in a place that teaches better, but I don't think that it will validate it no more. In my opinion, it makes your code more difficult to read. Someone coming along behind you must open several pieces of code to see what your program does.

  The more I watch your program, you want probably to validate and protect the SQL code that is in & sqltext, rather than the SQLExec. If you want it to be dynamic, I don't see what you can do.

  You could possibly launch an other App Engine as another process. You can use the object API ProcessRequest to plan the program through the process scheduler. You must pass your dynamic SQL code to the other program through a sort of serial control. In this way each SQL would go as a separate instance in process monitor and would go to success or no success individually. I still think it's too complicated.

  I hope these thoughts help. It looks like a difficult task.

• Handling SQL exceptions

  Hello

  I have a problem to understand how to manage the SQL Exceptions when using JdbcService in LiveCycle ephemeral process.

  Could you guide me to an article on handling sql exceptions?

  I see, that many services a 'bolt' in its visual representation (for example the Document FileUtilsService/Write) and it is possible to define alternative workflows by dragging the new road of bolt.

  What is the standard way to handle the sqlException exception then?

  Thank you.

  The latest version of LiveCycle contains a 'bolt' to catch exceptions.

  If you use 8.2, you can try to take advantage of the Exception event.

  Create a separate process and add an Exception start Point event. It must catch the exception.

• question about pl/sql exception

  Hi all. the following text is an excerpt from the documentation of the language reference PL/SQL Oracle® database oracle 11g Release 1 (11.1):
  
  Unhandled exceptions can also affect subroutines. If you exit a subprogram successfully, PL/SQL assigns values to parameters. However, if you come out with an unhandled exception, PL/SQL does not assign values for THE parameters (except if they are NOCOPY parameters). In addition, if a stored subprogram fails with an unhandled exception, PL/SQL does not restore database work carried out by the subprogramme of.
  
  Note the bold text, is this true? I'm curious about it, so I wrote the following example to test.
  
  -create a test table
  CREATE TABLE e AS SELECT * FROM HR. EMPLOYEES;
  
  -create p1 that will update a row in the table e
  CREATE OR REPLACE PROCEDURE p1
  IS
  ex EXCEPTION;
  e line % ROWTYPE;
  BEGIN
  Select * online e where employee_id = 100;
  
  Row.employee_id: = 100;
  Row.first_name: = 'yang ';
  
  -updated
  E UPDATE choose the LINE = line where employee_id = 100;
  - and trigger an error
  INVOKE;
  END;
  
  BEGIN
  -call the above procedure
  P1;
  END;
  
  -test update if successful
  Select * e where employee_id = 100;
  
  -the above query gives me
  Steven
  
  so my question is: am I right?

  Yang,

  This only was not always true... ?

  If a subpraogram fails and generates an unhandled exception, then it is up to the calling program decide what to do with it.

  If none of the programs in the hierarchy above manipulate... then the changes are cancelled because oracle a pseudo code around the entire block similar to:

  savepoint sp1;
    p1;
  if error then rollback to sp1;
  

  -Check this example...

  SQL> create table temp(
    2  id number);
  
  Table created.
  
  SQL> create unique index unq_id on temp(id);
  
  Index created.
  

  -If the program calling nt don't handle the error that the subprgram returns the error returned to Oracle and it cancels the entire transaction.
  -because it's the oracle of how works the transaction...

    1  create or replace procedure p1(i_number in number) as
    2  begin
    3    insert into temp values (i_number);
    4* end;
  SQL> /
  
  Procedure created.
  
  SQL> begin
    2     p1(1);
    3     p1(1);
    4  end;
    5  /
  begin
  *
  ERROR at line 1:
  ORA-00001: unique constraint (SCOTT.UNQ_ID) violated
  ORA-06512: at "SCOTT.P1", line 3
  ORA-06512: at line 3
  
  SQL> select * from temp;
  
  no rows selected
  

  -If the calling program catches the exception... it will speak to the future course of action... commit / rollback...
  In the code below, the error is ignored... and just pinted...

  SQL> ed
  Wrote file afiedt.buf
  
    1  begin
    2    p1(1);
    3    p1(1);
    4  exception
    5    when dup_val_on_index then
    6       dbms_output.put_line('duplicate value inserted...');
    7* end;
  SQL> /
  
  PL/SQL procedure successfully completed.
  
  SQL>  select * from temp;
  
          ID
  ----------
           1
  

  Hope that answers your question...

• Pure SQL Exception: Caused by java.lang.NullPointerException.

  Could not invoke the 'Query_XX_Flag' against the 'db' operation due to: []

  LIAISON. JCA-11633

  Pure SQL exception.

  Pure SQL select DECODE Execute (MSI. ATTRIBUTE5, 'Y', 'True', 'False') XX_flag of msi mtl_system_items_b where inventory_item_id =? and rownum = 1 failed.

  Caused by java.lang.NullPointerException.

  The pure SQL option is for only border use cases and provides simple but minimal functionality.  Maybe try the "Run an operation on a table" option instead.  This exception is considered non reproducible, probably due to an error of modeling.

  Version: Oracle soa suite 12.1.3 - jdk1.7 - (local) Windows 7 operating system

  I get the above exception in one of our Async BPEL of the process, and it happens like 1 in 5 cases.

  As you can see, the reason for the error is not really clear and I see nothing diagnosis either connects.

  And when I start this process from the console, it's getting completed successfully.

  We are not exceeding the number of DB connections either.

  Here's our design:

  BPEL Poller-> (several calls) Async BPEL process-> database adaptor with above query

  What could be wrong? What is the reason for this odd behavior?

  Thank you

  Prasanna

  This error could not be reproduced on the test environment, where the SOA server with oracle DB of the backend rather than javaDB on integrated server is installed...

  So if someone were unexpected exceptions on the local server and then try to test on the test/UAT/pre-production environments.

• Fuego Sql Exception

  Thank you very much.

  Hello

  For the transition you don't need to code.
  Return to your design process where you have designed the process.
  I hope that your code is in some automatic activity. So the automatic activity where you put your code right-click on this automatic activity and choose Add a conditional Transition then join or drag your mouse to the activity that you want to back up. Now, a wizard must encode called Transition of activity gives a name and in the second tab called Properties include the condition action is BACK. I hope it should work.

  Hello

  I am new to this concept, how to access SQL database via BlackBerry App. Can I access data using BES, please explain. What are futures contracts, I can use when I install BES on Enterprise Server.

  You can find more information on this topic by using the search function.

  BB does not provide a jdbc driver, this means that you will need to use a server as middleware between SQL and BB component.

  How communicate with this server, it is to you, send commands sql as strings, use a Web service, or something else.
