Pl/sql Package Tuning Tips

Hi Friends,
I have a requirement of Tunning a Pl/sql package.
Kindly share some tips on Tunning the Package.
Thanks & Regards
Dilip Nomula

Ramya,
Profiler is a plsql api which is very effective to find out that in the pl sql program of yours, where is the time spent and on which line? This, otherwise would be very tough to do as the pl sql programs are long and its tough to find the time spent on each line. Using the profiler, a line by line comparison can be shown to you. Here is a link how to use it,
http://www.oracle-base.com/articles/9i/DBMS_PROFILER.php
In addition to it, you can also combine dbms_trace. Combining this with the Profiler, you can have a complete info about the plsql package.

Tuning tips for sql

Can some one tell me the tuning tips for sql statements, please.
Thanks
Ajwat

Yes get EP (explain plan) going and try add /*+ RULE */ hint to your SIUD commands (Select/Insert/Update/Delete) . This changes the optimizer mode from CHOOSE to RULE, I find RULE uses indexes more often than CHOOSE (see example below).
select /*+ RULE */ c1,c2,c3 from t1 where n1=123
--[EP 1 results]
SELECT STATEMENT Optimizer=HINT: RULE
TABLE ACCESS (BY INDEX ROWID) OF T1
INDEX (RANGE SCAN) OF I_NU_T1_N1 (NON-UNIQUE)
select c1,c2,c3 from t1 where n1=123
--[EP 2 results]
SELECT STATEMENT Optimizer=CHOOSE (Cost=1 Card=1 Bytes=12)
TABLE ACCESS (FULL) OF T1 (Cost=1 Card=1 Bytes=12)
Look for any FULL TABLE SCAN entries in your EP results and try to get rid of them. As the above example shows, switching to RULE uses the index on table T1.
There are a while pile of other HINTS listed as well (other than just RULE) which are at ...
http://download-west.oracle.com/otndoc/oracle9i/901_doc/server.901/a87503/hintsref.htm#4894
There is a whole section on Oracle Performance at the following address...
http://download-west.oracle.com/otndoc/oracle9i/901_doc/server.901/a87503/toc.htm
the Hints section is Chapter 5
There are many more things to tuning tips, but by far, getting your SQL to use indexes is the primary one and you'll have to get EP results to see which indexes are being used (the FREE Toad program shows EP results nicely).
Hope this helps,
Tyler

EclipseLink-Redeploying a DBWS WS on PL/SQL package after changing return

Issue concerning: EclipseLink 2.4.1 (DBWS) on WebLogic
Hi,
I've created a DBWS webservice based on a Oracle (10g) PL/SQL package, by using EclipseLink DBWS builder. The PL/SQL function exposed as a webservice call has a Object type return type, e.g.:
create or replace type eclipse_type as
object
num number
create or replace package test_eclipselink_pkg as
function test return eclipse_type;
end;
As I understand it, EclipseLink-DBWS translates this Oracle object type to an Java type when calling the PL/SQL function over JDBC and translates the Java object to XML to be encapsulated in a SOAP message.
The problem is that when changing the specification of the return type (e.g. changing the name of the field num to nmb in the Oracle type eclipse_type) of the Oracle PL/SQL function, regenerating the webservice (WAR-file) with DBWS builder and redeploying it on WebLogic 10.3.6, calling the webservice results in a java.lang.reflect.InvocationTargetException.
Restarting the WebLogic server (or the appropriate managed server) resolves the problem, what shouldn't be a problem in a development environment, but is not always possible in a production environment.
The problem seems to be that redeploying the webservice doesn't result in the XR Operations/Queries being recreated and as a result the old result type definition is used.
Has anybody a solution for this problem?
Kind regards,
Jan

Hi,
I checked the logging while redeploying the WAR file. This part of the output seems to indicate, as you suggested, that the EcliipseLink session is not correctly logged of (InstanceAlreadyExistsException):

What I cannot see, is: who is responsible for this logout? This must be clear so I know I have to log a bug for WebLogic or for EclipseLink.
Anyone a suggestion how to determine this?
Thanks,
Jan

HOW TO: Post a SQL statement tuning request - template posting

This post is not a question, but similar to Rob van Wijk's "When your query takes too long ..." post should help to improve the quality of the requests for SQL statement tuning here on OTN.
On the OTN forum very often tuning requests about single SQL statements are posted, but the information provided is rather limited, and therefore it's not that simple to provide a meaningful advice. Instead of writing the same requests for additional information over and over again I thought I put together a post that describes how a "useful" post for such a request should look like and what information it should cover.
I've also prepared very detailed step-by-step instructions how to obtain that information on my blog, which can be used to easily gather the required information. It also covers again the details how to post the information properly here, in particular how to use the \ tag to preserve formatting and get a fixed font output:
http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
So again: This post here describes how a "useful" post should look like and what information it ideally covers. The blog post explains in detail how to obtain that information.
In the future, rather than requesting the same additional information and explaining how to obtain it, I'll simply refer to this HOW TO post and the corresponding blog post which describes in detail how to get that information.
*Very important:*
Use the \ tag to enclose any output that should have its formatting preserved as shown below.
So if you want to use fixed font formatting that preserves the spaces etc., do the following:
\   This preserves formatting
\And it will look like this:
   This preserves formatting
   . . .Your post should cover the following information:
1. The SQL and a short description of its purpose
2. The version of your database with 4-digits (e.g. 10.2.0.4)
3. Optimizer related parameters
4. The TIMING and AUTOTRACE output
5. The EXPLAIN PLAN output
6. The TKPROF output snippet that corresponds to your statement
7. If you're on 10g or later, the DBMS_XPLAN.DISPLAY_CURSOR output
The above mentioned blog post describes in detail how to obtain that information.
Your post should have a meaningful subject, e.g. "SQL statement tuning request", and the message body should look similar to the following:
*-- Start of template body --*

I'm sure that if you follow these instructions and obtain the information described, post them using a proper formatting (don't forget about the \ tag) you'll receive meaningful advice very soon.
So, just to make sure you didn't miss this point:Use proper formatting!
If you think I missed something important in this sample post let me know so that I can improve it.

The -dataSource parameter in assemble a web service from a PL/SQL package

When I use Web Service Assembler to assemble a Web Service from a PL/SQL package, I need to specify the dataSource parameter, e.g.:
java -jar wsa.jar -plsqlAssemble -sql pkgname -dataSource jdbc/MyDS -dbConnection ... -dbUser scott/tiger ....
The dataSource also needs to be pre-configured in the data-sources.xml in OC4J.
I am wondering why dataSource is needed here because the database connection information is already specified on the commandline ( dbConnection and dbUser).
If I have to specify dataSource, how do I configure data-sources.xml dynamically at run-time (e.g., adding entries)?
Thanks,
Jim

The -dataSource parameter specifies the data-sources.xml entry used at runtime. The database connection info is only for design time use. Typically you make sure data-sources.xml contains an entry with jndi-location of the same name you specifies for -dataSource. To configure data-sources.xml at runtime, it is out of the scope of web services. Please refer to OC4J admin guide. You can probably modify the data-sources.xml file and force OC4J to reconfigure based on the new data-sources.xml file.

Creating PL/SQL Package with all the types

CREATE OR REPLACE
TYPE rec_type AS OBJECT (
first_name VARCHAR2(20),
last_name VARCHAR2(20)
CREATE OR REPLACE
TYPE REC_TYPE_TAB AS TABLE OF rec_type
I am able to create the above types in oracle and used in PL/SQL packages. And like this I have somany types. I would like to if I can create a package with the types to make the life easier. Could you please tell me how to do it.
your help is greately appreciated..

When used correctly types can be the simplest solution.
For example when passing multiple values to a stored procedure. Avoiding the type in the below example would lead to further complexity and aggravation not lessen it.

Creating PL/SQL packages

Hello,
The problem I am confronted with is reusing generated models.
In the process of DataMinig several steps are used: prepare data, Attribute selection (using AI), and building, testing and applying models.
If PL/SQL packages are used two problems occur:
First: Long, hand driven process of building:
Model generation in ODM,
PL/SQL package building in ODM and Export to SQL file,
importing package to DB, compiling and running.
I am sorry, but I don't understand why is it necessary to export PL/SQL packages in a file? As if these products aren't both Oracle products?
Second: If data (in time) changes and AI selects new attributes, then all next steps fail, since column names, and even some values, are hard coded! Therefore it is necessary to go trough the build and export process all over again. This really hurts.
Do you have a suggestion how to get around this problem?
I already considered using a SPSS Clementine, but since it is not an Oracle product I still believe, the original Oracle solution should give me some advantages.
Oh and another issue.
I tried using PL/SQL generator (Ver.: 10.1.3.0.17) in JDeveloper (ver.: 10.1.3.0.4), but it gave me an error:
java.lang.NoClassDefFoundError: oracle/dmt/dm4j/DM4JConnectionManager

Hi,
The code generation available in ODMr would allow you to deploy the build, apply or test process as generated code.
I am not sure what your application goal is, but if you simply want to deploy a model be used in an apply process that is rather straight forward.
You would build the model using ODMr. Then create an Apply Activity, again using ODMr.
The Apply Activity can then be used to generate code (pl/sql) using the JDev RTM release (10.1.3.2 or above). We will also have a version that will work with SQLDev shortly.
The generated code is immediately placed into the db for you.
If you want to score in a separate db you can either create a db link from that db or move both the model and the apply pl/sql code to the new db (using dba utilities).
If you want to rebuild a model, where you would add/remove attributes, change transformations etc. then you will have to regenerate the code.
If you simply want to rebuild the model without changing any transformations and settings you could also deploy the model build generated code.
As for the JDev failure, we are going to look into that. Have you tried the JDev 10.1.3.3 release available on the Oracle web site?
Thanks, Mark

Creating PL/SQL package in SQL Developer 4.0.0.12

Hi,
I have built a model in SQL Developer 4.0.0.12 and I want to create it's PL/SQL package.
In ODMiner 11.1.0.4 from "Tools" > "Create pl/sql package" I can get a script for creating package and every thing is OK.
but in SQL Developer I select "Deploy" from every node's context menu and it generates a folder containing some scripts related to every node. I don't see any relevant script for creating any package.
How can I create relevant PL/SQL package from my workflow?
Thank you for any help you can provide in this situation.

Please refer to this White paper for how to generate PL/SQL package for workflow deployment:

How to get changes of a custom PL/SQL package updated in ISG?

Hi All,
I need some help on how to change a custom PL/SQL package in ISG integration repository:
I already uploaded my custom PL/SQL package to the integration repositoy some time ago. Now I have made some changes to PL/SQL record/table types defined in the package (added some fields and removed some others). These changed record/table types are used by a procedure I already uploaded to the integration repository. When regenerating the WSDL for my PL/SQL package in integration repository I get an error that the wrapper for respective procedure can't be found. When checking up the SQL types that were automatically generated (by JPublisher) for corresponding PL/SQL types, these generated SQL types are invalid...
So it seems that in one case JPublisher generated an empty SQL type (with no attributes). In another case JPublisher generated the SQL type with old attribute list, so it didn't adopt the changes of corresponding PL/SQL type in the package...
Can anybody tell me how to get the changes of a cusotm PL/SQL package updated in ISG? Or is there any possibility to first remove a whole PL/SQL package from the ISG integration repository (and getting rid of all old automatically generated SQL types), so that I can newly upload my PL/SQL package afterwards?
Thanks
Konrad

Thanks Daniel, for your reply...
(-> for info: I'm a colleague of Konrad...)
Yes, we used a higher version number - and the upload of iLDT file works fine...
But, the problem occured when generating the WSDL...
However, I think we have found an approach of how to get the changes of a custom PL/SQL package updated correctly in ISG:
1. Save a copy of PL/SQL package and then delete it in the database
2. Regenerate the WSDL for PL/SQL package in ISG (seems that all atutomatically generated JPub wrappers and SQL types are also deleted)
3. Restart all processes
4. Create the changed version of PL/SQL package in the database again
5. upload of iLDT
6. Regenerate the WSDL for PL/SQL package in ISG

Resmi, Have a read of [url http://forums.oracle.com/forums/thread.jspa?threadID=883293]this - JDeveloper 11g, as of today, doesn't (at least is not supposed to) support publishing PL/SQL procedures/packages as a web service.

How to Print the Value of a variable inside a PL/SQL package

Hi Friends,
Here is my Scenario
I have a PL/SQL Package. Let us call it Baseline Package.
This Package includes a dynamically built merge Statement.
Execute Immediate v_merge_query.
I have a procedure which replaces which few Keywords from the Package Text and Creates a new one depending on Inputs I provide. (This is something like a Code generator)
Now while Creating the new package, I need to print the Value of v_merge_query.... I Need s Static Query to be Printed inside the new package and not a dynamic query.
My Question is "Is there a way to print the value of the variable inside a different PL/SQL package?
Thanks in Advance,
Mohit

Print where?
That PL/SQL code is server-side code. It runs in an Oracle server process.
That server process does not have a keyboard. Or a screen/monitor. Or display canvas. Or an attached printer.
That server process is incapable of "printing" as that is not its job or responsibility and not part of its environment.
What is can do is record data for the client to look at afterwards. This can be done using static PL/SQL session variables. Or a SQL table.
The former is done by DBMS_OUTPUT - a very primitive interface for writing text into a static PL/SQL string array. That btw resides in expensive private process server memory. The client can query the array after a database call and render the contents.
PS. Also keep in mind that bind variables are critical for performance and server robustness - especially when (ab)using dynamic SQL.

Invoking Web Service From PL SQL package

Below is the sample code to invoke web service from pl/sql package using UTL_HTTP:
Declare
http_req UTL_HTTP.req;
http_resp UTL_HTTP.resp;
Begin
http_req :=
UTL_HTTP.begin_request
'http://'
|| lv_hosturl
-- || '.net/soa-infra/services/finance_rt/Payments/paymentsprocess_client_ep',
--new url
|| '.net/soa-infra/services/finance_rt/PaymentsReq/paymentsprocess_client_ep?WSDL',
'POST',
'HTTP/1.1'
UTL_HTTP.set_header (http_req, 'Content-Type', 'text/xml');
-- since we are dealing with plain text in XML documents
UTL_HTTP.set_header (http_req,
'Content-Length',
LENGTH (lv_soap_request)
UTL_HTTP.set_header (http_req, 'SOAPAction', '');
-- required to specify this is a SOAP communication
UTL_HTTP.write_text (http_req, lv_soap_request);
http_resp := UTL_HTTP.get_response (http_req);
UTL_HTTP.read_text (http_resp, lv_soap_respond);
UTL_HTTP.end_response (http_resp);
resp := XMLTYPE.createxml (lv_soap_respond);
End;

Hi,
there are a lot of option to make plsql web services .
First you can stay with jdev 10.1.3
Use the xmldb servlets
use jdev 11g tp4 to create plsql ws and upgrade to jdev 11g production
And I think in the next release of jdev it will be back , there are more options which disappeared like the adf bc sdo ws or jmx datacontrol etc.
thanks Edwin

Support for Creating Web Service from pl/sql package in JDeveloper 11

We have been creating all of our web services from pl/sql packages in our Oracle database using JDeveloper 10.1.3.1. I understand that this capability is not supported in Jdev 11. We have been mandated to either move up to JDeveloper 11, or consider switching to eclipse, or even VS2008 and run .NET services from IIS. I have seen work-around solutions using TopLink and Jdev 11. Are there plans to revive this feature in the near future? We're now looking at switching to .NET since we could scrap our OAS instances and use IIS to publish web services. The only reason we were sticking with Oracle was the ease in converting all our existing package to web services with Jdev.
Is anyone else in the same situation. If so, what solutions are you considering?

Error when publishing a PL/SQL package as a Webservice

Hi all,
I am using the JDeveloper (10.1.3.1.0) to publish a PL/SQL package as a Webservice, and I am having some troubles on the generation process.
The problem that I am facing is on the generated code for the database side, where some methods have a “$GET_” at the end of its name.
This “$GET_” is handled by the database as a special word, and the package can’t be compiled.
If the ‘$’ character is removed from all the methods, the package can be compiled and the Webservice works fine.
What’s wrong? Is there a bug on the generation process of the JDeveloper?

Rui Torres
