Query behave strange when called from java

Hi,
I had the same scenario a few times in two different queries in different databases (10g v2) and so not putting the query.
When I run the query from sqlplus/toad it takes less than a second
When I run it from java it takes about 5 minutes.
I could have thought it is something to do with Java ...
But when I rename the underlying table and use the new name in the query it takes normal (less than a second) time both in java and sqlplus/toad.
Before changing the name, I have tried rebuilidng the indexes and analyzing the table. The table has about 10 million rows and 13 indexes in one scenario and as less as 400k with 3 indexes in the other scenario. and in both cases updated once daily.
Each time this happends either a rename or dropping and recreating the table is solving the problem. I am lost.. any ideas what might be causing this problme; any solutions.
Thanks

Do whatever it is you are doing that makes it faster and run an Explain Plan capturing the output with DBMS_XPLAN. Also save off the stats collected on the table and indexes
Then, when performance deteriorates capture another plan along with the stats.
What is different?
A table with 13 indexes is an indication of an issue. I would suggest someone take a good look at why so many indexes are there.

How stored procedure get executed when called from java

When we create a stored procedure or function in oracle, it is compiled and stored there. From java when we call them no compilation is performed its a simple call. When a function or stored procedure is invoked from multiple instance of java objects(for a single session), does the stored procedure clone it self so that it can be called by different java objects which I think not possible at all. In such cases when one java object is interacting with the stored procedure, does other java objects go on a wait state. What happens if sessions are different.
Please help.

>
does oracle creates multiple instance of a particular stored procedure for different sessions or connections. if not then there might be some kind of waiting principle followed.. what happens exactly
>
What happens exactly is detailed in Chap. 14 Memory Architecture ni the Database concepts doc
http://docs.oracle.com/cd/E14072_01/server.112/e10713/memory.htm#i21266
The code is shared but the data isn't (see the lone exception to this below).
See the section on the Library Cache
>
Program Units and the Library Cache
The library cache holds executable forms of PL/SQL programs and Java classes. These items are collectively referred to as program units.
The database processes program units similarly to SQL statements. For example, the database allocates a shared area to hold the parsed, compiled form of a PL/SQL program. The database allocates a private area to hold values specific to the session that runs the program, including local, global, and package variables, and buffers for executing SQL. If multiple users run the same program, then each user maintains a separate copy of his or her private SQL area, which holds session-specific values, and accesses a single shared SQL area.
>
The exception is when code uses the SERIALLY_REUSABLE pragma. In that case the memory for package state is in the SGA and users do not have their own copy in their UGA.
See the SERIALLY_REUSABLE pragma in the PL/SQL Language doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/seriallyreusable_pragma.htm
>
The global memory for serially reusable packages is pooled in the System Global Area (SGA), not allocated to individual users in the User Global Area (UGA). That way, the package work area can be reused. When the call to the server ends, the memory is returned to the pool. Each time the package is reused, its public variables are initialized to their default values or to NULL.
Serially reusable packages cannot be accessed from database triggers or other PL/SQL subprograms that are called from SQL statements. If you try, the database generates an error.

Executable behaving different when called f/Java

I have an executable that is run from the command line which behaves differently when I run it from my application. The executable takes MP3s files as arguments and merges them together. When I use large files from within my app, it doesn't respond, but using the same files from the command line works fine. I was thinking it might be a memory thing, but the executable should get its own space seperate from the VM. Does anyone have any suggestions? Thanks!

I do not have the source for the executable, so I wouldn't be able to pull lines out of there. It works from my Java app when I pass in smaller files, so I know I have the syntax correct, but with larger files it hangs. When I run the same thing from the command line with the larger files it runs like a champ. I was trying to use my task manager (I'm on Win NT) to look at memory usage since the only variable seems to be file size, but nothing seems to indicate it is a memory issue.

JavaFX hangs when called from Java

Hello
I am developing a java application with a JavaFX gui, the communication from Java works with an java interface. The communication works,but after a few updates the javaFX code hangs and subsequently the Java code also hangs.
Is this a common problem, and so is there a common solution for this.

JavaFX UI calls need to be done on the Event Thread. So if your Java Application has multiple threads or runs on a different Thread to need to wrap all callbacks to JavaFX in a deferAction like this:
class YourFXClass extends YourJavaInterface {
   override public function someMethod(someArgument) {
        FX.deferAction(function() : Void {
              // doSomething with someArgument
    }

Java.lang.UnsatisfiedLinkError: when called from a jar file

I have a class that calls a custom dll file. If I dont package the class files and set my system PATH to the location of the DLL then the VM is able to find the dll and load it successfully.
However, when I package the class files into a jar file, I get "java.lang.UnsatisfiedLinkError: NetworkAdapters" eventhough the system PATH is set to the correct location.
I have also tried to packaging the dll with the class files but this has not made any difference.
Library is called from Java as follows:
static {
System.loadLibrary("NetworkAdapters");
When packaged the classes files exist in the following sub directories com\instem\hci\adapters
Any help appreciated.

Is it an executable Jar file?
The the DLL needs to sit in the same folders as the Jar itself.
(works for us).

when I run above query its coming in 1.2 seconds.but when comment subquery and call from package its taking 9 seconds.query returns more than 2000 records.i am not able to find the reason why it is taking more time when calling from package?

You are getting a different plan when you run it as PL/SQL most likely. Comment your statement:
SELECT /* your comment here */then find them in V$SQL and get the SQL IDs. You can then use DBMS_XPLAN.DISPLAY_CURSOR to see what is actually happening.

Java works stand alone does not when called from PL/SQL

I have this piece of code, which works as a standalone program: It takes in the en_var and returns a path.
But it wont work when called from a store procedure the line of code p = rt.exec("echo "+envar); returns a path as a standalone program returns null when called from a Oracle store procedure.
Thanks for any help just going around and round in circles.
import java.util.*;
class translate
public static String translatePath(String envar)
Runtime rt = Runtime.getRuntime();
int bufSize = 4096;
byte buffer[] = new byte[bufSize];
String path = null;
Process p = null;
String os = null;
String name = null;
String home = null;
String dir = null;
SecurityManager sm = null;
int len = 0;
try
System.out.println("Calling echo "+envar);
os = System.getProperty("os.name");
name = System.getProperty("user.name");
home = System.getProperty("user.home");
dir = System.getProperty("user.dir");
sm = System.getSecurityManager();
p = rt.exec("echo "+envar);
BufferedInputStream bis = new BufferedInputStream(p.getInputStream());
while ((len = bis.read(buffer, 0, bufSize)) != -1)
System.out.write(buffer, 0, len);
path = new String(buffer);
//p.waitFor();
bis.close();
return path;
catch(Exception e)
System.out.println("Exception "+e);
return "ProcessProblem";
//path = "/rims/live/log";

Still cant get it to work, it doesnt fall over anymore, but when I input $PATH, it will output $PATH instead of the path for $PATH i.e /rims/live: What does your program output please:
Here is my code:
import java.io.*;
import java.util.*;
class translate
     public static String translatePath(String envar)
          Runtime rt = Runtime.getRuntime();
          Process p = null;
          String echoOutput = null;
          int len = 0;
          try
               System.out.println("Calling echo "+envar);
               p = rt.exec(new String[]{"/bin/echo",envar});
               InputStreamReader isr = new InputStreamReader(p.getInputStream());
               BufferedReader br = new BufferedReader(isr);
               echoOutput = br.readLine();
               br.close();

SESSION EXPIRED and CPU Utilisation is 100% when called from Pro*C

Dear Colleague
We are having a production system developed using Pro*c and PL/SOL packages in HP Unix.
The system is doing the following,
A file will be decoded using Proc and data will be load into 3 temporary tables (permanent table used for temporary) using SQLLoader. Then it calls a PL/SQL package which will process the data in the temporary tables and will store the summary information in Transaction table and will returns a unique id to the calling Pro*c module. The whole process is completed in a single process/oracle session.
The PL/SQL package, join the 3 Temporary tables and retrieve the data into an Oracle object(Collection) and process it. Then the processing summary will be loaded into Transaction table and return the Primary key.
Now the problem is, when the temporary tables are loaded with more than 200,000 rows, in some cases the system is running for hours before it finish. And during the process the session shows as EXPIRED in the database and CPU utilization for the respective ProcessId in Unix is almost 100%. Then after a while the session comes alive and finishes the process.
And for some other cases, with same row count, the entire process finished in seconds.
If the same process (PL/SQL package) when run directly using a separate session inside the database(and the temporary tables are still available), rather than calling from Pro*c, it finishes in seconds, where it took hours when called from Pro*c.
It will be highly appreciated, if anyone let me know, what actually is wrong. whether it is the resource allocation or should there any known problem in calling huge PL/SQL packages from Pro*C.
we are using Oracle 10g and HP-UX ed42 B.11.31 U System.

Sajid

Dear Colleague
I just want to rephrase the problem again.
We have a Pro*C application. This will read the binary file and dump the data in ascii format to a data file. Then, within from the pro*C, 14 Dynamic tables will be created using EXEC SQL EXECUTE IMMEDIATE statement, each having almost a maximum of 45 columns. Also, created INDEXES to the tables in the same way from Pro*C.
And Control file will be created as follows
OPTIONS (SILENT=(FEEDBACK)) UNRECOVERABLE
LOAD DATA
INTO TABLE FILENAME_BCI_USED
FIELDS TERMINATED BY '|'
TRAILING NULLCOLSColumns Listed
Then Sql loader will be called using system commands (from pro*C itself) to loead the data into the table, as follows.
   sprintf(syscommand,"sqlldr %s CONTROL=%s DATA=%s log=%s rows=5000 direct=true", glb_connect_string,ctl_file,data_file, log_file );
   ret_value = system(syscommand);data loaded successfully.
Then the Pro*C will call a PL/SQL package for processing the data.
The PL/SQL package, to process the data, dynamically construct the below query and use it for the reference cursor to retrieve data and load into a collection.
v_sql_query := 'SELECT '|| '/*+ index(b '||p_File_Name ||'_1) index(b '||p_File_Name ||'_2) index(s '||p_File_Name ||'_3) index(s '||p_File_Name ||'_4) index(s '||p_File_Name ||'_5) index(s '||p_File_Name ||'_6) index(e '||p_File_Name ||'_7)*/'   || '

When we checked the session activity, it is showing the same query for a very long time.
Where as files with 100K or less rows are getting processed in a minute.
And the performance for 150K+ rows is inconsistent, that when we isolate the package and run it directly calling from oracle, it is getting executed in less than 4 minutes. Whereas it takes 100+ minutes from Pro*C.

Stored Procedure Does Not Run Properly When Called From Portlet

We have a simple Java portlet that calls a PL/SQL stored procedure which we wrote. The stored procedure sends a large number of emails to users in our corporation using the "utl_smtp" package. The stored procedure returns a count of the emails back to the Java portlet when it's finished. This number is displayed in the portlet.
Our problem:
The stored procedure functions as expected when run from a PL/SQL block in SQL*Plus, and the Java portlet calls the procedure properly when sending out a smaller number of emails (Less than 200 usually). When we get into a higher number of emails the procedure hangs when called from the portlet, but it STILL functions properly from SQL*Plus. It does not return the number of emails sent
and the Java portlet is unable to return a SQLException. Also, we have noticed that emails are sent at a much slower pace from the stored procedure when it's called from the portlet.

Any Ideas?

JTextField update problem when called from PropertyChangeEvent

Hi,
I'm trying to create forms that can be dynamically loaded with Class.forname(formName).
Those forms should always inherit some methods that make it easy to pass data to
them and receive data from them. The idea is that the data comes from a table which
sends a hashmap (String column/JTextField-name + String Value pairs) with firePropertyChanged
as soon as a new row is seleceted. The JTextFields in the form are marked with setName("FieldName") that has to correspond to the name of the columns of the table.
My problem is that I can't update the fields in my form when I'm calling getRow(HashMap)
from within propertyChangeEvent but that's necessary to keep the forms flexible.
JTextFieldName.setText(newText) just won't work. But it works when I call getRow(HashMap)
from the constructor. SwingWorker and threads to update the form didn't help.
I don't need to call pack() / update() / repaint() on the JFrame, do I ??
update() / validate() / repaint() etc. didn't work on the JTextField themselves.
Below is the code for one of the test-forms (just a JPanel that is inserted in a frame)
with all of it's methods. Does anybody have a solution to this problem ??
Thanks for taking time for that !!

The problem of the change in the form not being comitted is that
I forgot SwingUtilities.invokeLater(makeChanges); in the bottom
part in public void propertyChange(java.beans.PropertyChangeEvent evt)
after having created a new Runnable.
Changes to the UI often have to be comitted by SwingUtitlities.invokeLater()
though I don't know that much about Swing yet.
Thanks to everybody who tried to solve that problem.

Set the default field value to transaction code field, when calling from WD

Hi all,
Can we pass the value in a input field of a standard transaction calling from WD application. Suppose we are calling a transaction VA03 in an external window, then how will be pass the value in the VBAK_VBELN screen field.
Is there any way to pass the value to this transaction field. I have also tried out to set the parameter ID 'AUN' for VA03 transaction VBELN field. But it did not work for me.
Is there any way to set the default field value to transaction code field, when calling from WD?
Please suggest, if anyone have any idea.
Thanks
Sanket

Hi,
I am using the below code to open a standard transaction. It will help you to explain my point more easily.
DATA: url TYPE string,
          host TYPE string,
          port TYPE string.
*Call below method to get host and port
cl_http_server=>if_http_server~get_location(
     IMPORTING host = host
            port = port ).
*create URL
CONCATENATE 'http'
'://' host ':' port
'/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction=' 'VA03'
   INTO url.
*get the window manager as we are opening t code in external window.
DATA lo_window_manager TYPE REF TO if_wd_window_manager.
DATA lo_api_component TYPE REF TO if_wd_component.
DATA lo_window TYPE REF TO if_wd_window.
lo_api_component = wd_comp_controller->wd_get_api( ).
lo_window_manager = lo_api_component->get_window_manager( ).
call the url which we created above
lo_window_manager->create_external_window(
EXPORTING
url = url
RECEIVING
window = lo_window ).
lo_window->open( ).
Note*
One more query I want to add to this thread, that is there any possibility to call a custom transaction as well?

Is it possible to call diff report queries when called from form

hello all
I want to know if it is possible to call different report queries when called from oracle 9i form .
i tried to use he
SET_REPORT_OBJECT_PROPERTY(REPORT_QUERY = 'q_diff' )
option and actualy called the report name
but it dint seem to work !!!
also is it possible to chng the title of the browser at runtime

Sandeep,
this property is used with passing Record Groups as data parameters from Forms.
Passing the query name indicates that the values contained in the record group substitutes the result of the named query. This may work in client/server Reports, but it definitively doesn't work on teh Web because you can't pass a Record Group as a data parameter in this environment.
Te problem with changing a Reports query is that you must meet the same number of columns and column types as they exist in the Report. I didn't spend much time with XML based runtime customization in Reports. I think that you can change the Reports query through this feature. In Forms you would create the XML file using text_io and the merge it with an existing Reports. I never did this before. So it could be that all I am saying does not work in the end. Before following this idea, you may better ask in teh Reports forum on OTN if it is possible to use the runtime customization feature to modify the Reports query.

Running BDC in 'A' mode when called from Enterprise portal

HI All,
I have created a RFC which contains a BDC program that update data in SAP R/3. The RFC is called from Enterprise portal. Is it possible to run the rfc in A(all screen display) mode while calling from EP. I have tried it but it gives following 2 errors on EP
cm_no_data_received
rfc_error_communication
what changes i have to do so that i can run the BDC in 'A ' mode when called from Enterprise portal

it would not be related to EP administration issues but something to do with GUI usage. it is loggically fare enough not to give options of viewing the debug screen in as it might concern security issues inway the data could be edited at any point of time. Moreover the screens u see in R3 are ABAP but whereas in EP it is purely based on Java and the calls to SAP is done via JCO thus enabling ABAP functionalities in EP. Maybe for these technical reasons or constraints it wont be possibel to view the screen in EP eventhough u had ext.bp activated

How can i measure BAPI runtime which has called from JAVA

Hi abapers
how can i get run time for BAPI called from JAVA through JCO.
i know that i can use SE30 from ABAP by executing from SAP.
may be ST05 useful for me i did it but when display trace
i am getting big list by seeing this list i am not able to find the runtime for that BAPI.
please any one can explain
reagdrs
ramesh

Hi Ramesh,
Irrespective of whether the call is from an external system or within sap, the bapi will be executed in R/3 only.
So, you can safely measure the runtime using se30 only.
If it is taking more time when called from JCo , then you can be sure that the problem is not with SAP and is actually due to the JCo connectivity with R/3.

Ravi
