Db_load in Java

Hi!
Is there any way to execute the utility db_load "db_load -r lsn -h . container.dbxml" from a Java application? Is there any similar function?
I can execute it from the shell, but I would like to call this from the Java code.
Thank you

Hi,
best to my knowledge it's not possible. But this is an administrative task and is not supposed to run frequently. If you still need to access this functionality from Java, you can run a process from Java code that runs db_load, or extend Java bindings.

Java edition compatible with standard edition?

Hi
I have a database created using Java edition 3.2.44
I want to write an application in C++ which reads this database using the standard Berkeley DB (possibly at the same time as the java application is also accessing them). Are the database files compatible?
I'm not too hopeful since the the database files are named something like 00000000.jdb and je.lck.
Any help appreciated
Nick

Hi Nick,
This FAQ entry addresses this question:
[http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#2|http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#2]
(a small additional information to this entry is that DPL API has been introduced for BDB as well in 4.7.25)
As explained, the on-disk format for the database files is different. You should dump the database created with JE (using the DbDump/com.sleepycat.je.util.DbDump utility: [http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/je/util/DbDump.html|http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/je/util/DbDump.html]) and load it using BDB before opening it in a a program using one of the BDB APIs (using the db_load utility: [http://www.oracle.com/technology/documentation/berkeley-db/db/utility/db_load.html|http://www.oracle.com/technology/documentation/berkeley-db/db/utility/db_load.html] )
If you face any issues with dumping/loading the database let me know.
Regards,
Andrei

Question related to db_load

Hi,
I am using 4.7.25 lib version. In our production environment we frequently need to move databases around and we use db_dump and db_load utilities. On more than one occasions, db_loads take a long time. Obvious enough, whenever that happens, the database under operation is also big but I just wanted to find out that the default db_dump and load process themselves are optimized or should we be doing some preprocessing on data before we use db_load on it. For example I have heard people sorting data in oracle database before loading it and that making a huge performace impact on load part.
I can get some specifics for my environment to you if I know what I should be looking at. some of the points that may be helpful are.
1) Highly transactional app
2) keys are UT-8 strings, calues are serialized java objects
3) While running db load env is down and we run recovery before we do db_load. (Reason for this is that if I don't remove env files from target environment, I get env incompatible). Could db_load be slow because of absence of env params as I supply them with API.
Thanks and regards,
Shishir

I would really appreciate any help or pointers here.

Erro de SYSFAIL e Queda do Ambiente JAVA (PI)

Bom Dia
Estou num projeto de NFe e atualmente esta acontecendo o seguinte cenário de Erros:
    Na SMQ2 , quando apresenta um aumento nas filas de Mensagens , aparece SYSFAIL em determinadas Filas , todas as outras travam , aumenta o numero de Filas.
   Com essa mensagem de SYSFAIL nas filas , o serve0 (Parte JAVA do PI) cai e após isso estou tendo que efetuar manualmente um STOP/START em todos os canais de comunnicação para que os R/3 voltem a emitir NFe.
    Isso esta ocorrendo com mais frequência após inserir uma nova empresa para emissão de NFe.
    Alguem poderia me ajudar a entender por que ocorre o SYSFAIL as mensagens travam e derruba o ambiente JAVA ?

if (wt > max)This forum doesn't quite handle <> properly. The greater and less than symbols. So above you will see > this is the html character code for a greater than symbol so please read it as such.
And then if wt is greater than max then it will say "Your overweight".
But I can't figure out how to include it in the above program. Becuase it won't run in paint, atleast it won't the way I have done it previously. So can you think of any other ways?
Help much appreciated,

SSO java sample application problem

Hi all,
I am trying to run the SSO java sample application, but am experiencing a problem:
When I request the papp.jsp page I end up in an infinte loop, caught between papp.jsp and ssosignon.jsp.
An earlier thread in this forum discussed the same problem, guessing that the cookie handling was the problem. This thread recommended a particlar servlet , ShowCookie, for inspecting the cookies for the current session.
I have installed this cookie on the server, but don't see anything but one cookie, JSESSIONID.
At present I am running the jsp sample app on a Tomcat server, while Oracle 9iAS with sso and portal is running on another machine on the LAN.
The configuration of the SSO sample application is as follows:
Cut from SSOEnablerJspBean.java:
// Listener token for this partner application name
private static String m_listenerToken = "wmli007251:8080";
// Partner application session cookie name
private static String m_cookieName = "SSO_PAPP_JSP_ID";
// Partner application session domain
private static String m_cookieDomain = "wmli007251:8080/";
// Partner application session path scope
private static String m_cookiePath = "/";
// Host name of the database
private static String m_dbHostName = "wmsi001370";
// Port for database
private static String m_dbPort = "1521";
// Sehema name
private static String m_dbSchemaName = "testpartnerapp";
// Schema password
private static String m_dbSchemaPasswd = "testpartnerapp";
// Database SID name
private static String m_dbSID = "IASDB.WMDATA.DK";
// Requested URL (User requested page)
private static String m_requestUrl = "http://wmli007251:8080/testsso/papp.jsp";
// Cancel URL(Home page for this application which don't require authentication)
private static String m_cancelUrl = "http://wmli007251:8080/testsso/fejl.html";
Values specified in the Oracle Portal partner app administration page:
     ID: 1326
     Token: O87JOE971326
     Encryption key: 67854625C8B9BE96
     Logon-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_login
     single signoff-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_logout
     Name: testsso
     Start-URL: http://wmli007251:8080/testsso/
     Succes-URL: http://wmli007251:8080/testsso/ssosignon.jsp
     Log off-URL: http://wmli007251:8080/testsso/papplogoff.jsp
Finally I have specified the cookie version to be v1.0 when running the regapp.sql script. Other parameters for this script are copied from the values specified above.
Unfortunately the discussion in the earlier thread did not go any further but to recognize the cookieproblem, so I am now looking for help to move further on from here.
Any ideas will be greatly appreciated!

Pierre - When you work on the sample application, you should test the pages in a separate browser instance. Don't use the Run Page links from the Builder. The sample app has a different authentication scheme from that used in the development environment so it'll work better for you to use a separate development browser from the application testing browser. In the testing browser, to request the page you just modified, login to the application, then change the page ID in the URL. Then put some navigation controls into the application so you can run your page more easily by clicking links from other pages.

SSO between a Java EE application (Running on CE) and r/3 backend

Hi All,
Over the past few days I have been trying to implement a SSO mechanism between NW CE Java Apps and R/3 backend without any success. I have been trying to use SAP logon tickets for implementing SSO.
Below is what I need:
I have a Java EE application which draws data from R/3 backend and does some processing before showing data to the users. As of now the only way the Java App on CE authenticates to r/3 backend is by passing the userid and pwds explicitly. See sample authentication code below:
BindingProvider bp = (BindingProvider) myService;
Map<String,Object> context = bp.getRequestContext();
context.put(BindingProvider.USERNAME_PROPERTY, userID);
context.put(BindingProvider.PASSWORD_PROPERTY, userPwd);
Now this is not the way we want to implement it. What we need is when the user authenticates to CE ( using CE's UME) CE issues a SAP logon ticket to the user. This ticket should be used to subsequently login to other system without having to pass the credentials. We have configured the CE and Backend to use SAP logon tickets as per SAP help.
What I am not able to figure out is: How to authenticate to SAP r/3 service from the java APP using SAP logon tickets. I couldnt find any sample Java code on SAP help to do this. (For example the above sample code authenticates the user by explicitly passing userid and pwd, I need something similar to pass a token to the backend)
Any help/pointers on this would be great.
Thanks,
Dhananjay

Hi,
Have you imported the java certificate into R/3 backend system ? if so.
Then just go to backend system and check on sm50 for each applicaion instance of any error eg.
SM50-> Display files (ICON) as DB symbol with spect.(cntrlshiftF8)
You will get logon ticket details.
with thanks,
Rajat

Partner Application written in other language than PL/SQL and Java

I have an application written in another language than PL/SQL or Java. I want to integrate this application as an Partner apps where I use the same user repository as Portal.
Can I integrate the application by calling a stored PL/SQL-procedure based on the PLSQL SSO APIs examples that authenticates the user based on the username/password in portal and redirects the user to the application ?
Are there any examples / references where this has been done ?
Jens

Check out the PDK referance for URL-Services, which allow you to integrate with any web based service/content.

Possibility of drawing numbers on java bouncing balls?

Can anyone show me how to put numbers on these moving balls in my code. I need the numbers 1-60 on them. I have two sets the red and white. Here is my code. Any help is appreciated. I am trying to write a program to represent the powerball.

This must be the first sensible post you've ever made. At least you're able to copy someone else's response and pretend you know something.

Java Bouncing Balls Threads problem?

Hello,
I am working on a homework assignment to represent a java applet with some bouncing balls inside. So far so good. The balls bounce and behave as they are supposed. The only thing is that I want to make 2 buttons, Start and Stop (this is not part of the assignment, but my free will to provide some extra stuff :) ) . I am implementing Runnable for the animation and ActionListener for the buttons. I did research on threading, but somehow I am still not getting quite the result I want. The applet is not displaying my buttons (I guess I am not implementing them correctly) and I dont know whether I have synchronized the threads correctly as well. So, I am asking for some guidance how can I do this? Thanks in advance!
As a remark, I am new to Java, as I am just starting to learn it and this is my first assignment.

well i didnt arrive at this point without reading tutorials and researching.... sometimes other people can spot your mistakes a lot easier than you can, that's why I asked for help. 10x anyway for the interest!

Problem with Java and Memory

hi,
i have 512MB Memory in my pc, but the SUN ONE uses only 64MB.
i dont know where is the problem. is it in the Run time of java of in the GUI Studio from Sun?
how can i increase the number 64?
i do nothing eccept java on this pc.
thx

Did you encounter a java.lang.OutOfMemoryError when running java? If not, nothing needs to be fixed.
Still, you can specify the initial and max heap size for your java application on startup. Use the options -Xms<size> and -Xmx<size>, respectively. To see the non-standard options of your JVM, type "java -X"
in a command shell.
