Oracle debug session exits instantly for trigger - sql

I am trying to debug a compound trigger. I compiled it for debug,and put breakpoints on the trigger and hit "debug". Then it prompts me a window for a PL/SQL block. I entered my sql statement, and hit "OK".
The debug session just ends instantly
I got following message in the Debugging Message window:
Connecting to the database EFTS.
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '127.0.0.1', '6503' )
Debugger accepted connection from database on port 6503.
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.DISCONNECT()
Process exited.
Disconnecting from the database EFTS.
Debugger disconnected from database.
Strangely, the debugger works for stored procedures. I am able to trace through the procedures line by line. However, for TRIGGER, it just ended instantly.
Trigger Declaration:
create or replace TRIGGER
MySchema.T_EVNTS_UPSERT
FOR INSERT OR UPDATE ON MySchema.MyTable
COMPOUND TRIGGER
SQLDeveloper Version: the latest
Oracle Version: 12c

Make sure you have changed this setting
It should say instead 'Step Into'
Also ensure the lines of pl/sql with breakpoints are executable lines of code, otherwise they'll be ignored.

Disable auto-commit for execution procedures on PL/SQL Developer

I'm currently using PL/SQL Developer to run some queries at my job, and my colleague uses TOAD to run the EXECs for procedures, since TOAD does not autocommit them. So, whenever I need to run a procedure, I must send him the codes and wait for him response.
Is there a way to stop PL/SQL Developer from autocommiting them?
I've already looked in the preferences and couldn't find any option to stop this from happening. The option "autocommit after Execute" is disabled, as well as all other autocommit functions I could find.
I'm running the procedures using
Begin
PROCEDURE
End
since neither EXEC or EXECUTE seem to work
Here's the code I'm supposed to run (and works perfectly with TOAD)
exec PWSYS.MAINT.MOVE_INCIDENT('here goes some data','here goes more data');
It doesn't run with EXEC on PL/SQL Developer (it displays error ORA-00900: invalid SQL statement), so I tried this
Begin
PWSYS.MAINT.MOVE_INCIDENT('data here','data here as well');
End
It runs perfectly, but it also autocommits, and THAT'S my problem.
So, in summary, I need a way to stop it from autocommiting, or a way to rollback the data I've inserted/changed.
Thanks in advance

ORA-02048 - Attempt to begin distributed transaction without loggin on

anyone know something about this error?
ORA-02048: attempt to begin distributed transaction without logging on
ORA-02063: preceding line from ..dblink
It occurs when I invoke since Java a PL/SQL Package that contains dblinks to access to other database for insert data. The dblink works good with other clauses, but not in this Package.
If I invoke this PL/SQL Package since TOAD, it works good.
I'm trying to reproduce this error, and I see this error arises from a pattern:
When I click the button which makes the PL run, the log shows me an error "ora-02292 integrity constraint child record found", and the next time I click the button, appears the error "ORA-02048", it is like the first error did lose the connection with remote database.
Thanks in advance
Without seeing a minimal testcase that demonstrates the problem, it's impossible to say.
However, looking up the error message:
-bash-4.1$ oerr ora 2048
02048, 00000, "attempt to begin distributed transaction without logging on"
// *Cause: client program must issue a distributed transaction login.
// *Action: contact support.
So, I'd recommend contacting Oracle support and opening an SR. But, the first thing they're likely to ask for is a working test case that demonstrates the problem.
The problem was thatI have different procedures, like that:
procedure1 -> (call) -> procedure 2 -> (call) -> procedure3
In procedure3 I have a clausure with dblink that insert into a remote table.
Procedure1 catchs the exceptions that may occur in procedure 2 and procedure3.
The problem is when an exception is throw in procedure3. In this case the rollback placed in the exception catch of procedure1, should finish the transaction, but it isn't working as I expected. The transaction is this case remains open and the second time in the procedure executions, oracle shows me the ORA-02048 error.
The solution was moving the exception catch into procedure3.

SQL Server stored procedure no statements run when from RPC

I have a SQL Server 2000 database with a stored procedure that deletes a row from a specific table, given its id. When I call the stored procedure from VB.NET, it does not delete the row, but running the same script directly on the database via SSMS, it works.
Here's my chain of events:
Start SQL Server Profiler to watch all calls to the database. I have
it setup to track when stored procedure starts, completes, and even
on SQL statements start/complete within that stored procedure.
Call stored procedure via VB.NET dll.
Stop the profiler trace to avoid excessive data to dig through.
Select from table, and see that the row still exists.
View the profiler trace, which only shows RPC:Starting, SP:Starting, RPC:Completed. No inner statements are traced, which verifies why the row wasn't deleted since the delete statement never fired.
Copy/paste the EXEC call directly from the RPC:Starting trace entry from when it was called via VB.NET, into SQL Server Management Studio query window pointed to the same database with same credentials.
Start profiler again.
Execute EXEC statement from bullet 6 in SSMS.
Stop profiler.
Select from table, and see that the row GOT DELETED like it should.
View the profiler trace, which shows SP:Starting, all statements starting/completed including the DELETE statement, and SP:Completed.
Why would running it via RPC make it not execute any of the statements in the proc, but running directly acts as it should?
EDIT: Below is my VB.NET code. This is the same code we use in over 100 other places:
Dim paramRowID As New SqlParameter("#RowID", sRowID)
Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(oConn, "spDeleteRow", paramRowID)
See SqlHelper source here.
EDIT: I hate myself right now. :) SQL threw an exception "nvarchar is incompatible with image" about another parameter that I was passing NULL to. SSMS didn't worry about the type, but VB.NET did since I didn't explicitly tell it that it was of type image. Once I defined that param, it worked. I wish profiler would have told me there was an error though.
Any help would be appreciated,
Greg
That would be because SSMS does not call an RPC but a batch. There is no way in fact to call a RPC from SSMS since you cannot declare a parameter, which is what differentiate an RPC call from a batch call in TDS:
2.2.1.3 SQL Batch To send a SQL statement or a batch of SQL statements, the SQL batch, represented by a Unicode string, is copied into the data section of a TDS packet and then sent to the database server that supports SQL. A SQL batch may span more than one TDS packet. See section 2.2.6.6 for additional detail
2.2.1.5 Remote Procedure Call To execute a remote procedure call (RPC) on the server, the client sends an RPC message data stream to the server. This is a binary stream that contains the RPC name or numeric identifier, options, and parameters. RPCs MUST be in a separate TDS message and not intermixed with SQL statements. There can be several RPCs in one message. See section 2.2.6.5 for additional details.
So monitor instead for the SQL:BatchCompleted event and you'll see your SSMS statement(s).
Does the user the application is using to connect to sql have permission to execute stored procedures? That is the first thing I would verify.

Ignoring SQLPLUS commands in JDBC

I have a .sql file that contains below statements:
SET LINESIZE 2000
WHENEVER SQLERROR EXIT 1 ROLLBACK
WHENEVER OSERROR EXIT 1 ROLLBACK
SET PAGESIZE 0
SET HEADING ON
SET FEEDBACK OFF
SET VERIFY OFF
INSERT INTO TABLE_A
--get some value from TABLE B that will be added in Table A....
COMMIT;
EXIT;
When I run this SQL in my SQL Editor (TOAD/SQL Navigator etc.) , it works fine. I see some messages though when SQLNavigator execute this command:
SQL*Plus command ignored.
Processing ...
WHENEVER SQLERROR EXIT 1 ROLLBACK
SQL*Plus command ignored.
Processing ...
WHENEVER OSERROR EXIT 1 ROLLBACK
SQL*Plus command ignored.
Processing ...
SET PAGESIZE 0
When I run this SQL through JDBC, i get an exception:
Caused by: java.sql.SQLException: ORA-00922: missing or invalid option
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331)

at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3285)
at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:3368)
I'm assuming this error is because JDBC is not able to understand SQLPlus statements and failing. Is there a way I can tell JDBC to ignore those statements and just run the main SQL? Or to resolve this I just need to modify the SQL file by removing the SQLPlus statements?
You'll need to remove the SQL*Plus commands from the file.
JDBC is intended to be a database-agnostic interface so it is designed to work the same with a variety of different database engines. SQL*Plus commands are designed to work just with SQL*Plus connecting to an Oracle database (though other tools that support Oracle databases will often support a subset of SQL*Plus commands as well). It wouldn't make sense for JDBC to know about what constitutes a SQL*Plus command so it has no way to figure out what is a SQL*Plus command or to filter them out.
Beyond that, simply removing the SQL*Plus commands will change the semantics of the script. The WHENEVER SQLERROR and WHENEVER OSEROR commands instruct SQL*Plus to issue a rollback in the event of an error (which it sounds like your script generates). You'd need to code that logic into your JDBC application if you want to match the behavior.
When you run these statements through TOAD, etc. they usually parse the text either by a delimiter (e.g. semi-column) or by line feed and run the statements separately. However, when you send the whole text to JDBC, it's probably trying to run it all at once, hence the error. You may have to parse the statements and separate them properly before sending to JDBC.

Basic SQL trigger will not fire

This is my very first trigger and I'm not sure I have it set up correctly. I have a table called PayTypes. Here is my trigger syntax:
ALTER trigger payTypes_trigger
on PayTypes
AFTER INSERT, UPDATE, DELETE
as
PRINT 'AFTER TRIGGER EXECUTED SUCESSFULLY'
I run this with a breakpoint on the first line, update my VB.NET datagridview (which updates and saves just fine), but the breakpoint never gets hit.
Am I going about the setup of the trigger incorrectly?
There are two possible issues:
1) You are using VS Express, which does not support this behavior
2) You are not stepping into the trigger from a stored procedure.
I haven't tested this myself, but according to this MSDN documentation, you need to step into a stored procedure that will cause the trigger to fire in order to debug the trigger.
