Dbms_xslprocessor package problems in PL/SQL

Hi all :)
I was wondering if anyone has any ideas about this problem I'm having:
When using the dbms_xslprocessor in PL/SQL, I consistently get dropped connections when trying to either transform a document, or search a document via XPath. So, for instance, if I call dbms_xslprocessor.selectSingleNode('XPATH'), the connection will drop out with the following error (I'm calling a stored procedure here):
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Similar problems happen on XMLType.transform(stylesheet).
I've only managed to have this happen when transforming or searching documents that are not in the default (i.e., xmlns="") namespace, but I can't get rid of the namespace (too much other code is relying on it being there).
What's even stranger is that the XSLPROCESSOR package works, but DBMS_XSLPROCESSOR package does not. Unfortunately, the XSLPROCESSOR package doesn't seem to handle namespaces well, and inserts seemingly random namespace declarations in the transformation results (for instance, on the root element, it puts in "xmlns:xmlns='http://www.w3.org/2000/xmlns/'") or redeclares namespaces on nodes that already have that namespace defined for them by their parents. Namespace prefixes, too.
Does anybody have any ideas as to what this might be?
Thanks in advance,
Constantine

I should also mention that I'm ABSOLUTELY sure that the stylesheets I'm using for transformation are correct as of XSLT ver. 1.0 -- multiple external processors (Xalan and MSXML, specifically) give the correct result on the same stylesheet.

Problems with PL/SQL packages

Hello,
I face the following problem with PL/SQL stored procedures. The Oracle
version is 8.0.5 on Windows NT 4. The PL/SQL package has a set of procedures and functions.
The main procedure of the PL/SQL package is triggered from VC++ executable. If for some reason,
an exception is caught in the stored procedure (like no_data_found
exception), then the following problem occurs.
If we try to trigger the stored procedure again through the VC++ executable,
the variables in the stored procedures have the values as in the previous
execution. They are not getting initialised. (The same database connection
is used in VC++ executable).
Currently, only if a new connection to the database is used , the problem is
solved.
Also, change in the input parameters of the procedure is not reflected, once the procedure fails because of any exception. Only the input which was given during the time of execution when the procedure failed,is considered.
What could be the reason for this problem and how can this be corrected?
Please send in your suggestions.
Thanks and Regards,
Ramya Priya

Hi Keith,
I am connecting to the database as the package owner..
I have noticed earlier that I have problems when capturing triggers also.. The content of one large trigger contains 36371 characters and when capturing it from DB, the content was truncated to 28020 characters in Designer.
Our ideas with capturing the DB packages/procedures were to use the Designer as version control system.
We wanted to have all objects used in a project in Designer.. entities, tables, triggers, packages, procedures, Forms files, etc. in order to make a configuration for a project release.
Thank you,
Claudia

How to avoid performance problems in PL/SQL?

How to avoid performance problems in PL/SQL?
As per my knowledge, below some points to avoid performance proble in PL/SQL.
Is there other point to avoid performance problems?
1. Use FORALL instead of FOR, and use BULK COLLECT to avoid looping many times.
2. EXECUTE IMMEDIATE is faster than DBMS_SQL
3. Use NOCOPY for OUT and IN OUT if the original value need not be retained. Overhead of keeping a copy of OUT is avoided.

Susil Kumar Nagarajan wrote:
1. Group no of functions or procedures into a PACKAGEPutting related functions and procedures into packages is useful from a code organization standpoint. It has nothing whatsoever to do with performance.
2. Good to use collections in place of cursors that do DML operations on large set of recordsBut using SQL is more efficient than using PL/SQL with bulk collects.
4. Optimize SQL statements if they need to
-> Avoid using IN, NOT IN conditions or those cause full table scans in queriesThat is not true.
-> See to queries they use Indexes properly , sometimes Leading index column is missed out that cause performance overheadAssuming "properly" implies that it is entirely possible that a table scan is more efficient than using an index.
5. use Oracle HINTS if query can't be further tuned and hints can considerably help youHints should be used only as a last resort. It is almost certainly the case that if you can use a hint that forces a particular plan to improve performance that there is some problem in the underlying statistics that should be fixed in order to resolve issues with many queries rather than just the one you're looking at.

Help!! package problem in jsp

hello,
i have problem that all class is packaged in test folder. and the test folder is located inside the C:\Tomcat_5.0\webapps\BB2004\WEB-INF\class.

You can't refer to a pl/sql package constant in a sql statement.
Create a function that returns the constant value and then refer to the function in a sql statement.

Create or Replace Package syntax different in SQL Navigator?

Hi,
I compared the same piece of code in both toad and sql navigator.
In toad, the syntax for Package was as follows:
CREATE OR REPLACE package body name_of_package
but in SQL Navigator, the same code is displayed as follows:
package body name_of_package
does SQL navigator hide the "Create or replace" keywords? or does it automatically know that they belong there?

Is Sql navigator an Oracle product? IIRC Larry spent already all his pocket money on buying Sun.
Kindly do not clutter up this forum with questions on products not developed by Oracle.

Run Multiple SSIS Packages in parallel using SQL job

Hi ,
We have a File Watcher process to determine the load of some files in a particular location. If files are arrived then another package has to be kick-started.
There are around 10 such File Watcher Processes to look for 10 different categories of files. All 10 File Watcher have to be started at the same time.
Now these can be automated by creating 10 different SQL jobs which is a safer option. But if a different category file arrives then another job has to be created. Somehow I feel this is not the right approach.
Another option is to create one more package and execute all the 10 file watcher packages as 10 different execute packages in parallel.
But incase if they don’t execute in parallel, i.e., if any of the package waits for some resources, then it does not satisfy our functional requirement . I have to be 100% sure that all 10 are getting executed in parallel.
NOTE: There are 8 logical processors in this server.
(SELECT cpu_count FROM sys.dm_os_sys_info
i.e., 10 tasks can run in parallel, but somehow I got a doubt that only 2 are running exactly in parallel and other tasks are waiting. So I just don’t want to try this option.
Can someone please help me in giving the better way to automate these 10 file watcher process in a single job.
Thanks in advance,
Raksha

Hi Jim,
For Each File Type there are separate packages which needs to be run.
For example package-A, processes FileType-A and package-B processes FileType-B. All these are independent processes which run in parrallel as of now.
The current requirement is to have File Watcher process for each of these packages. So now FileWatcher-A polls for FileType-A and if any of the filetype-A is found it will kick start package-A. In the same way there is FileWatcher-B, which looks for FileType-B
and starts Package-B when any of FileType-B is found. There are 10 such File Watcher processes.
These File Watcher Processes are independent and needs to start daily at 7 AM and run for 3 hrs.
Please let me know if is possible to run multiple packages in parallel using SQL job.
NOTE: Some how I find it as a risk, to run these packages in parallel using execute package task and call that master package in job. I feel only 2 packages are running in parallel and other packages are waiting for resources.
Thanks,
Raksha

Hi,
One prior post discussing the use of Java 7 is:
SQL Developer 3.0 and Java SE 7?
There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
#SetJavaHome ../../jdk
SetJavaHome C:/Program Files/Java/jdk1.6.0_26
#SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,

Executing procedure in package problem

Hi, i have a procedure called Newcar. i have now created a package and put the Newcar procedure inside the package body. but when i want to invoke it (to put data) by running execute packageTest.Newcar('Ferrari', 007) i get ORA-00900: invallid sql statement. what is wrong? the package spec and body gets created ok:
CREATE OR REPLACE PACKAGE packageTest IS
PROCEDURE Newcar(vname IN VARCHAR2, vreg IN NUMBER);
END packageTest;
CREATE OR REPLACE PACKAGE BODY packageTest IS
PROCEDURE Newcar
(vname IN VARCHAR2, vreg IN NUMBER)
IS
l_vreg NUMBER;
BEGIN
l_vreg := vreg;
IF vreg > 999 THEN
l_vreg := 999;
END IF;
INSERT INTO CARS (carname, carreg)
VALUES
(vname, l_vreg);
END Newcar;
END packageTest;
/

Worked for me. Are there other details that might be relevant? The table definition perhaps? Triggers? Can you post similar output from your SQL*Plus session?

2 PROCEDURE Newcar(vname IN VARCHAR2, vreg IN NUMBER);
3 END packageTest;

Package created.
SQL> CREATE OR REPLACE PACKAGE BODY packageTest IS

12 INSERT INTO CARS (carname, carreg)
13 VALUES

15 END Newcar;
16 END packageTest;
17 /
