Problem accessing j2ee application in oracle 10g AS
Hi,
I have Oracle 10g AS installed on a Linux 4.0 system. I have deployed an ear file in the AS. The problem is while accessing the application, the login screen is showing, but after submitting it says "Page can not be displayed". The control is not passed to the Action class.
Please help me ...
SantoshHi Santosh,
This problem does not sound like an OC4J issue (unless this is a set up issue), it sounds more like your code is not passing the control to your Action class. Please check your struts configuration and make sure your mappings are set up correctly.
Hope this helps.

Problems with the installation if oracle 10g
hi everybody,
I am using windows xp pro service pack 2. While trying install
oracle 10g. I faced a problem 'Error in writing to
directiory c:\document and settings\Owner\Local
Settings\TEMP\OraInstall. Please ensure that this
directory is writable and has at least 45 MB of disk
space. Installation cannot continue.' I have 40GB disk
space left and i am logged in as an administrator with all privileges.
thanks
mfg RRI think I remember encountering something similar on the very same platform (XP pro, 10g (or 9i second ed.) and 2nd service pack). I am using Windows Services for Unix (SFU - a free download from Microsoft @ http://www.microsoft.com/windows/sfu/default.asp ). I used SFU from within a command tool to change the privileges. If you are a unix person who are trying to do things like installing/managing Oracle on windows, I highly recommend installing SFU. After I changed the privileges, it worked just fine. Currently I am running 9.2.0.5 on windows xp pro and testing 10g on another xp pro box. Both installation was successful.
hope this proves useful -
Problem storing Russian Characters in Oracle 10g
We are facing an issue in one of our sites which is in Russian Language. Whenever data is submitted with Russian Characters it saves it as Question mark(upside down) in the database. Database is not supporting these characters.The character encoding is done in UTF-8 format from the front end.
This code use to work fine with Oracle 9i database but after the upgradation to Oracle 10g this problem has started occuring. We have not made any changes to the code after the upgradation of the database.
How can we resolve this and what are the settings that we can do to make this work fine?What is your database character set and national character set?
SELECT *
FROM v$nls_parameters
WHERE parameter like '%CHARACTERSET';Are you storing the data in CHAR/ VARCHAR2/ CLOB columns? Or NCHAR/ NVARCHAR2/ NCLOB?

Problem with retrieving data from Oracle 10g / PHP4.3 / Apache 1.3.27
Hi,
I re-open a new thread following the opened post 'Getting RPMs for php-oracle for PHP4.3 on RHEL 4.0 and issue with OCI8 '
I could re-installed PHP4.3 and apache 1.3.27 from the normal tar package (./configure then make) - I had some issues with the RPMs packages before.
I could connect successfully PHP4.3 to my Oracle 10g DB with no issues by using some of the (deprecated) functions contained in oracle.so library in command line mode by executing a simple PHP script ;-)
But ...when I try to execute the same script (a simple log on to the DB) or the application throught my web browser there are some errors in the apache error_log file that crash the process:
[Wed Jul 25 13:19:23 2007] [notice] child pid 25450 exit signal Segmentation fault (11)
[Wed Jul 25 13:19:31 2007] [notice] child pid 25451 exit signal Segmentation fault (11)
*** glibc detected *** realloc(): invalid size: 0x08338898 ***
[Wed Jul 25 13:19:42 2007] [notice] child pid 25441 exit signal Aborted (6)
*** glibc detected *** realloc(): invalid size: 0x08338898 ***

[Fri Jul 27 04:39:56 2007] [notice] child pid 20550 exit signal Segmentation fault (11)
After some investigations it looks like this is due to the connection of Oracle 10G and php.
I tried to recompile Apache as the following:
# cd /usr/src/apache_1.3.xx
# make clean
# LIBS=-lpthread ./config.status
# make
# make install
but the issue is the same ...
How can I workaround that issue and fix it in order to connect to Oracle 10 G by using PHP4.3 / apache 1.3.27 ?
I need to use the oracle.so library to avoid to re-rewrite all my application ...
Any help much very appreciated !
Cheers
DominiqueYou are in unchartered territory. But check the common "gotcha" and
make sure that all the Oracle environment variables are set in the
shell that starts Apache. Load the script <?php phpinfo(); ?> in a
browser and see that whatever variables you need are set in the
Environment section. See the section "Oracle Environment Variables
for Connections" in Underground PHP and Oracle Manual
I suspect it would be beneficial to migrate the PHP code to oci8.
Check table 16-1 in Underground PHP and Oracle Manual for the mapping
between 'oracle' and 'oci8' functions.

Exchange setup error: "There was a problem accessing the registry on this computer"
Hi,
i am trying to install Exchange 2007 SP1 in a Windows 2003 Server standard 32 bits version.
During the "Readiness checks" i received the next error in "Hub transport role prerequisites":
Error:
There was a problem accessing the registry on this computer. This may happen if the Remote Registry service is not running; it may also indicate a network problem.
Remote Registry service is running. I've searched for the error in google and in some topics appears that the error is due to the "Client for Microsoft Networks" and "File and Printer Sharing" is not installed in the LAN properties. The server has 2 network cards and in both of them is checked. One of the connections is disabled.
I dont know what more to do, any help will be appreciated.
ThanksNo, firewall is disabled.

Error while migrating from ms access 2003 db to oracle 10g in sqldeveloper
Hello,
i am working on migration project from MS access 2003 to Oracle 10g on windows XP sp2 plateform using SQL developer.
it went quit smoothly till the "capture microsoft access" .so in this step the sql developer opens the access db in background... but while opening the file in background it gives error
Object library not registered i tried many workaround but of no use..
anybody's help in this regard would be well appreciated.
thanks.Hi,
Did you follow all the steps in the SQL*Developer documentation about preparing the Access database for migration -
Oracle® SQL Developer User’s Guide Release 3.0 -
2.2.4.3 Before Migrating From Microsoft Access
and -
Oracle® SQL Developer Supplementary Information for Microsoft Access Migrations Release 3.0
2.4 Preparing the Microsoft Access Database for Capture
The error also indicates there may be a problem with your Access installation so could you check that everything is okay with that ? I have found references that indicate a re-install of Office/Access will prevent the error.

Problem with JDBC driver for Oracle 10g
Hi.
I've successfully accessed a MySQL database via a DataSource from a servlet (that uses a DAO). However, when I try to do the same with an Oracle 10g Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter of which I downloaded this afternoon as the latest driver JAR available on the Oracle site. As with the MySQL driver, I've placed it in the commons\lib folder within Tomcat. (I've also, of course, made the necessary modifications to server.xml and web.xml.)
Upon examining the ReadMe file at the top of the Oracle download page, I found that the oracle.jdbc.driver package is now deprecated and all references to oracle.jdbc.driver should be replaced with oracle.jdbc. However, I got a similar error message when I tried this modification. Upon examining the contents of ojdbc.jar, I found that the driver was there and that it was, in fact, still oracle\jdbc\driver\OracleDriver!
It appears as though the Oracle site has not been updated with a driver that matches its latest documentation. However, this does not explain why the driver is not even being loacted when it is in the correct place. Can anybody shed any light on this? Any help would be much appreciated.
Thanks in anticipation.
Cheers.
JanI've successfully accessed a MySQL database via a
DataSource from a servlet (that uses a DAO). However,
when I try to do the same with an Oracle 10g
Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
That's different from a ClassNotFoundException.
>
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter
of which I downloaded this afternoon as the latest
driver JAR available on the Oracle site. So you got ojdbc14.jar or ojdbc14_g.jar under the 10g drivers?
As with the
MySQL driver, I've placed it in the commons\lib
folder within Tomcat. I think it's a better idea to put in the WEB-INF/lib directory of your Web app rather than commons/lib. WAR files are a very good idea, too.
(I've also, of course, made the
necessary modifications to server.xml and web.xml.)So you're using a JNDI data source? It sounds to me like that's where the problem is.
You should not have to edit the server.xml at all. If you put the <ResourceParams> in a context XML file with the same name as your WAR file into the TOMCAT_HOME/webapps directory it'll be picked up automatically. (It might also be accessible in the META-INF directory for your app, but I haven't done it that way.)
Upon examining the ReadMe file at the top of the
Oracle download page, I found that the
oracle.jdbc.driver package is now deprecated and all
references to oracle.jdbc.driver should be replaced
with oracle.jdbc.
However, I got a similar error
message when I tried this modification. Upon
examining the contents of ojdbc.jar, I found that the
driver was there and that it was, in fact, still
oracle\jdbc\driver\OracleDriver! The fully-resolved class name you should be using MUST match the class that's in the ojdbc14.jar that you're using. Look in the JAR for the definitive answer: the one that I downloaded is still using the oracle.jdbc.driver package for OracleDriver.class. Ignore the docs - use the name that's in the JAR.
It appears as though the Oracle site has not been
updated with a driver that matches its latest
documentation. That often happens with docs.
However, this does not explain why the
driver is not even being loacted when it is in the
correct place. Can anybody shed any light on this?
Any help would be much appreciated.I think the problem lies in your web.xml and server.xml
I'd recommend that you decouple the JDBC from the Web app for now. See if you can connect to Oracle using a simple desktop app and leave the Web piece out of the equation for now. Once you can do that, you'll be certain that the parameters you're using are correct and you can turn your attention to getting the Tomcat configuration right.
PS - I'm using Oracle 9.2.0.1 and Tomcat successfully right now, so it can be done. -

Problem in importing data in oracle 10g from 9i backup
Hi ,
Am trying to import data in oracle 10g..but it does not importing constraints, and stop doing anything by the msg.
About to enable constraints.....
after this msg it does not work.
plz help,
Regards,
NehaHi Neha,
You have a lot of options. I'll supose you can test first, and you're using an export file.
First forget about the data, think in your database structure. So you can do this:
exp userid=... file=exp_norows.dmp full=y rows=n statistics=none
Now you have the structure of your database. Create the database, in 10g, empty, check you have all filesystem, etc. for you new datafiles. And do the import with parameter ignore=y, you'll see a lot off errors on SYSTEM schema, don't worry about it.
Now you have the structure of you database in 10g. You can take a look in the import log file, looking for some possible errors come from your schemas. so check the objects, and check the schemas.
Bear in mind things like CONNECT role in 9i it's different in 10g, you can't create db_links in 10g with "IDENTIFIED BY VALUES" because you'll get an ORA-00600, etc.
Well, fix all problems on source database (9i) and repeate this procedure until you don't recieve any more errors (not a SYSTEM schema errors).
When you have everything solved, you can try to import the data.
I hope, this method can help you. If you have any problem do not hesitate to ask me.

Unix permission problem for external table in oracle 10g, sun solaris
Hello All,
I'm facing a problem in accessing external table which has stumped me a bit.
What I'm looking for is to use a external table with restricted permission to Others(770) on unix.
Would appreciate if someone helps me out here.
Here are the steps:
1.create directory ext_tab_dir1 as '/home/ravi/test'
2.grant read,write on directory ext_tab_dir1 to scott
3.CREATE TABLE scott.emp_load1(employee_number CHAR(5))
ORGANIZATION EXTERNAL (
type oracle_loader
default directory ext_tab_dir1
access parameters (
records delimited by newline
fields terminated by ' '
optionally enclosed by '"'
missing field values are null
location ('info.dat')
Now I have added unix user oracle to unix group myDbGroup and provided myDbGroup read/write/exec permission on directory /home/ravi/test.
info.dat has been placed in /home/ravi/test.
#pwd
/home/ravi
#ls -l
drwxrwx--- 2 ravi myDbGroup 512 Mar 7 17:35 test
I have manually logged in as user oracle and successfully created a sample file in /home/ravi/test.
-rwxrwx--- 1 ravi myDbGroup 13 Mar 7 17:33 info.dat
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 sampleFile
I then connect to the db using sqlplus as ravi and do a
#select * from scott.emp_load1
I get the following error
ERROR at line 1:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04063: unable to open log file emp_load1_18567.log
OS error Permission denied
ORA-06512: at "SYS.ORACLE_LOADER", line 19
After this, I gave full permission to /home/ravi/test
drwxrwxrwx 2 ravi myDbGroup 512 Mar 7 17:35 test
#select * from scott.emp_load1
And this was successful.
It created a log file in /home/ravi/test
-rwxrwx--- 1 ravi myDbGroup 13 Mar 7 17:33 info.dat
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 sampleFile
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 emp_load1_18567.log
Now what stumped me is the owner and group owner of the file emp_load1_18567.log.
It is same as the sampleFile which I created manually!!
From this it can be deducted oracle is not using user id oracle while reading/writing to the unix directory but somehow assigning user id oracle as owner to the log file at the end.
If someone has encountered this problem earlier or has some info about this...pls share.
Regards,
RavinandanThanks for the reply.
I have earlier checked this with NOLOGFILE option.
But no luck.
I would like to add one more detail(which I missed earlier) about the problem.
If I give 750 access to /home/ravi(That is read/exec to Group and none perm to Others),
I will get the same error(KUP-04063: unable to open log file emp_load1_18567.log).
This obviously means oracle is not even able to access the directory(Although unix user oracle has access via the group perms). -
Two problems in BSBM benchmark of Oracle 10g with Jena Adaptor 2.0
Hi, all.
I'm proceeding BSBM benchmark for Oracle 10g with Jena Adaptor 2.0.
I'm using the codes that were introduced in Jena Adaptor 2.0 guide document, and I've applied Jena patches to Oracle 10g (10.2.0).
But, two problems are occured in benchmark process.
The first problem is
that 250k dataset(consisted of 250030 triples) loading time elapses over several hours, (See below code snippet.)
and the other is
that exceptions are occured in some sparql query execution.
I used below queries which have no error in query syntax.
I confirmed that through other benchmark tests.
In case of oracle benchmark test, quey1 is ok. but, query2 makes exception.
Please, look about the Exception message below.
What should I do for getting much better benchmark result?
I appreciate any help or any hint.
Best regards ~

The data loading was slow because incremental loading API was used. Please take a look at OracleBulkUpdateHandler. There is an addInBatch API that you can use.
Now regarding queries, Jena Adaptor v2.0 was primarily designed for Oracle Database 11g Release 1.
Recently, a new version of Jena Adaptor has been released and it's optimized for Oracle Database 11g
Release 2.
Is it possible to run your BSBM benchmark tests against Oracle Database 11g Release 2 using the latest
Jena Adaptor (http://forums.oracle.com/forums/ann.jspa?annID=1179) ?
Thanks,
Zhe Wu
