Problem with httpd and oracle database

hi
i have oracle linux with oracle database 11gR2
i install php with oci as the following link :
http://oss.oracle.com/projects/php/dist/documentation/installation.html
but when i try phpinfo() i found just only
*" /etc/php.d/oci8.ini"* in the result
and when i test connection i have this error
*" Fatal error: Call to undefined function oci_connect() "*
so what is the best way to install oci on oracle linux ?

What version of the OS are you using? Any clues in the syslog and httpd log? Are you using SELinux, which is often an overlooked issue?
Can you provide more details?
so what is the best way to install oci on oracle linux ?According to the instructions, if support is needed: http://www.oracle.com/technetwork/topics/php/zend-server-096314.html

ResultSets based on a wildcard are generally treated as views by Oracle, meaning they are not updatable no matter how you create your statement. Try either "select swa.* from sw_assets swa" or "select all from sw_assets swa", that should get around the problem.
Also (just being thorough) make sure that you specifically created your statement as being updatable (stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE) ).
I would not normally expect a NullPointerException when encountering this "feature", but then I don't often use the ODBC bridge.
Good luck! I hope this helps.

Problem with Unicode and Oracle NCLOB fields

When I try to INSERT a new (N)CLOB into an Oracle database, all is fine until I use a non-ASCII character, such as an accented roman letter, like the "�" (that's '\u00E9') in "caf�" or the Euro Currency symbol "?" (that's '\u20AC' as a Java character literal, just in case the display is corrupted here too). This doesn't happen with "setString", but does happen when streaming characters to the CLOB; however, as Oracle or the driver refuse strings larger than 4000 characters, and as I need to support all the above symbols (and many more), I'm stuck.
Here's the background to the problem (I've tried to be detailed, after a lot of looking around on the web, I've seen lots of people with similar problems, but no solutions: I've seen and been able to stream ASCII clobs, or add small NCHAR strings, but not stream NCLOBs...).
I'm using Oracle 9.2.0.1.0 with the "thin" JDBC driver, on a Windows box (XP Pro). My database instance is set up with AL32UTF8 as the database encoding, and UTF8 as the national character set.. I've created a simple user/schema, called LOBTEST, in which I created two tables (see below).
The basic problems are :
- with Oracle and JDBC, you can't set the value of a CLOB or NCLOB with PreparedStatement's setString or setCharacterStream methods (as it throws an exception when you send more than 4000 characters)
- with Oracle, you can only have one LONG VARCHAR-type field per table (according to their documentation) and you MUST read all columns in a set order (amongst other limitations).
- with a SQL INSERT command, there's no way to set the value of a parameter that's a CLOB (implementations of the CLOB interface can only be obtained by performing a SELECT.... but obviously, when I'm inserting, the record doesn't exist yet...). Workarounds include (possibly) JDBC 4 (doesn't exist yet...) or doing the following Oracle-specific stuff :
INSERT INTO MyTable (theID,theCLOB) VALUES (1, empty_clob());
SELECT * FROM MyTable WHERE theId = 1;
...and getting the empty CLOB back (via a ResultSet), and populating it. I have a very large application, that's deployed for many of our customers using SapDB and MySQL without a hitch, with "one-step" INSERTS; I can't feasibly change the application into "three-step INSERT-SELECT-UPDATE" just for Oracle, and I shouldn't need to!!!
The final workaround is to use Oracle-specific classes, described in:
http://download-east.oracle.com/otn_hosted_doc/jdeveloper/904preview/jdbc-javadoc/index.html
...such as CLOB (see my example). This works fine until I add some non-ASCII characters, at which point, irrespective of whether the CLOB data is 2 characters or 2 million characters, it throws the same exception:
java.io.IOException: Il n'y a plus de donn?es ? lire dans le socket
     at oracle.jdbc.dbaccess.DBError.SQLToIOException(DBError.java:716)
     at oracle.jdbc.driver.OracleClobWriter.flushBuffer(OracleClobWriter.java:270)
     at oracle.jdbc.driver.OracleClobWriter.flush(OracleClobWriter.java:204)
     at scratchpad.InsertOracleClobExample.main(InsertOracleClobExample.java:61)...where the error message in English is "No more data to read from socket". I need the Oracle-specific "setFormOfUse" method to force it to correctly use the encoding of the NCLOB field, without it, even plain ASCII data is rejected with an exception indicating that the character set is inappropriate. With a plain CLOB, I don't need it, but the plain CLOB refuses my non-ASCII data anyway.
So, many many thanks in advance for any advice. The remainder of my post includes my code example and a simple SQL script to create the table(s). You can mess around with the source code to test various combinations.
Thanks,
Chris B.

The solution to this is to use a third-party driver. Oranxo works really well.

Problem with applications and accessing database

Hi
I have a serious problem with my applications.I was trying to change "users"'s folder icon so I changed the setting in information.I don'y know what I did but It made these problems:
many of applications does not open for example
itunes-->The folder "iTunes" is on a locked disk or you do not have permission...
picasa alerts me with a database error
yahoo messenger just pops up once and doesn't open.
firefox the same problem
net monitor alerts with a database problem.
evernote same problem
all of my address book is erased.
I think somehow I removed the db files or I changed the permission and the programs can not access to their db files.

don't know the last thing I have done was trying to change the icon and after that I found out about the problem.Maybe sth else caused the problem . anyway I copied all of my files to a new user and I removed the user with problems & everything is ok here.thank u all.

Problem with DataLoader and Oracle 8.1.6

I am currently running WebLogic Commerce Server under the following
configuration.
1. Solaris 8
2. WebLogic Server 5.1
3. WebLogic Commerce Server 2.0.1
4. Oracle 8.1.6
5. JDK 1.2.2
I have followed the instructions completely as it relates to running
with Oracle. Everything works fine up to the point in which I run the
DataLoader.sh script.
The DataLoader.sh script almost completes. However, after some time is
spend loading items, I see the following WebLogic dumb, and the
DataLoader.sh scripts quits.
Some other points. I am using the Oracle thin driver (Classes111.zip).
The size and date of the classes111.zip are as follows.
Date: 12/14/1999
Size: 1.4Meg
Any ideas as to what the problem is.

Javier, these are database parameters picked p from the init.ora of that database. To check the values of these parameters, logon to the database via SVRMGRL as the DBA and then execute the command :
SVRMGR>SHOW PARAM
This lists all the database paramaters. Also check if the Oracle MTS Service is actually running.

Problems with installation of Oracle Database 11g, Enterprise edition

I am having trouble with the whole DHCP setting on my windows vista business OS.
I went throught the steps to install a loopback adapter which is supposed to be a solution for DHCP-enabled computers. When I check to see if I have a loopback adapter, it is showing that it is the "local area connection 2."
But at some point during the installation, it says that I need to make the loopback adapter the primary network setting. Is this what is preventing a successful installation? I went through the installation process to the end despite this error message and it seemed to install ok. I created a database using the Database Config Manager. Now I am having trouble accessing this database. Is this related to the error message I described above?
I created a username and password at the database creation page.
When I go into command prompt I type in "sql plus" and then my username and password.
But it says "ORACLE not available."
Any help would be much appreciated.

Don't bother with a loopback adapter unless you are using a laptop that needs Oracle to work whether connected or unconnected to the business network. Much simpler to just arrange for DHCP to assign you a fixed IP address (a lease reservation).
It's the change of IP address which trips Oracle up, not the existence of DHCP. So if you can make sure your IP address will be the same, no matter how you acquire it, that's all you have to do.
Installing a loopback adapter which isn't the primary interface at the point you install Oracle will mean your installation will get very confused as to whether to address things via the 127... address or the "normal" IP address. And yes, at that point, you'll not be able to connect to instances, or run listeners or do all sorts of other things reliably.
If it were me, I'd uninstall the mess you probably now have as far as Oracle goes, install something like VirtualBox (free) or VMware Workstation (costs) and enjoy your Oracle experience inside the confines of a virtual machine whose networking setup you can configure and control to your heart's content, without it screwing up your real machine's ability to connect to your work's network when it needs to.

Problems with classpath and oracle drivers

Hi, i've developed an application that uses oracle drivers "classes12.jar" using Eclipse. While i was writing the code, i manually specified the classpath which contains "classes12.jar" file using Eclipse's own configuration tool and now it works perfect when i run it under Eclipse. I then tried to run it using dos prompt but when i tried to run the program i got "ClassNotFoundException: oracle.jdbc.driver.oracledriver". As you can guess, i thought that was a classpath issue so i set the classpath as follows:
set CLASSPATH=C:\oracle\ora92\jdbc\lib
where the directory "C:\oracle\ora92\jdbc\lib" is the one that contains classes12.jar file which i had also specified using Eclipse before.
After that, i recompiled my application and tried to launch it as follows:
->javac Test.java
->java Test
But then i got the following runtime error:
Exception in thread "main" java.lang.NoClassDefFoundError: Test
Since this happened after i manually set CLASSPATH variable, this has something to do with that. What should i do now? Thanks in advance.

Correct - the JAR has to be spelled out in the CLASSPATH.
I'd also recommend that you not set CLASSPATH using a system environment variable. Better to use the -classpath parameter on javac.exe when you compile and java.exe when you run. Put the command into a script that you invoke when you start up the app. It'll document the fact that it's needed for anyone that comes after you and relieves you from having to change the CLASSPATH on machines you deploy to. And, for good measure, app servers like Tomcat and WebLogic totally ignore the system CLASSPATH. I don't even have one.

Discussion Forum Portlet - Problems with JAVA and UTF8?

Hi
I installed the Discussion Forum Portlet successfully. It also seems that almost everything works fine. There's only a problem if I have new posts that include special German characters (Umlaute) like ä, ö, ü or special French characters like é, è or ç. They are saved correctly in the table but if you view the post the characters are not displayed correctly.
Example
input: ça va?
result: Ã§a va?
I know that there are problems with Java and UTF8 Database. Is there a possibility to change this (bug)?
Regards
Mark

Slow Problems with Oracle Forms 10g and Oracle Database 11g

Hi, I wonder if there is a compatibility problem between Version 10.1.2.0.2 32 Oracle Forms and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production. This is because my application runs correctly on a version of Oracle Database 10g, and when we migrated the database to an Oracle Database 11g, slowness problems came out.
Thanks.

We have the same issue happening with our custom forms and with some of the standard forms in EBSO. So far we have found that the form invoking a view causes ridiculous slowness in opening the form (40 mins). Using a table access has shortened the open time significantly. At this time Oracle DBAs at OOD have no clear idea why it is happening.
we are on 11.1 database with 11.5 EBSO

Problem with trigger and entity in JHeadsart, JBO-25019

Hi to all,
I am using JDeveloper 10.1.2 and developing an application using ADF Business Components and JheadStart 10.1.2.27
I have a problem with trigger and entity in JHeadsart
I have 3 entity and 3 views
DsitTelephoneView based on DsitTelephone entity based on DSIT_TELEPHONE database table.
TelUoView based on TelUo entity based on TEL_UO database table.
NewAnnuaireView based on NewAnnuaire entity based on NEW_ANNUAIRE database view.
I am using JHS to create :
A JHS table-form based on DsitTelephoneView
A JHS table based on TelUoView
A JHS table based on NewAnnuaireView
LIB_POSTE is a :
DSIT_TELEPHONE column
TEL_UO column
NEW_ANNUAIRE column
NEW_ANNUAIRE database view is built from DSIT_TELEPHONE database table.
Lib_poste is an updatable attribut in TelUo entity, DsitTelephone entity, NewAnnuaire entity.
Lib_poste is upadated in JHS table based on TelUoView
I added a trigger on my database shema « IAN » to upadate LIB_POSTE in DSIT_TELEPHONE database table :
CREATE OR REPLACES TRIGGER “IAN”.TEL_UO_UPDATE_LIB_POSTE
AFTER INSERT OR UPDATE OFF lib_poste ONE IAN.TEL_UO
FOR EACH ROW
BEGIN
UPDATE DSIT_TELEPHONE T
SET t.lib_poste = :new.lib_poste
WHERE t.id_tel = :new.id_tel;
END;
When I change the lib_poste with the application :
- the lib_poste in DSIT_TELEPHONE database table is correctly updated by trigger.
- but in JHS table-form based on DsitTelephoneView the lib_poste is not updated. If I do a quicksearch it is updated.
- in JHS table based on NewAnnuaireView the lib_poste is not updated. if I do a quicksearch, I have an error:
oracle.jbo.RowAlreadyDeletedException: JBO-25019: The row of entity of the key oracle.jbo. Key [null 25588] is not found in NewAnnuaire.
25588 is the primary key off row in NEW_ANNUAIRE whose lib_poste was updated by the trigger.
It is as if it had lost the bond with the row in the entity.
Could you help me please ?
Regards
Laurent

3     data4     1     g4As you can see in 10g I don't have the last row, it seems that Oracle 10g doesn't recognize the LEFT OUTER JOIN.
Is this a bug?, Metalink says that sometimes we can have an ORA-0600 but in this case there is no error returned, just incorrect results.
Please help.

Hi A_Non.
Thanks a lot, I tried with this:
SELECT
     t.id,
     x.dat,
     y.seqno,
     y.id_real
FROM
     xml_test t,
     XMLTABLE
          '/msg/data/fields'
          passing t.xml
          columns
               dat VARCHAR2(10) path 'dat',
               id XMLTYPE path 'id'
     )x,
     XMLTABLE
          'id'
          passing x.id
          columns
               seqno FOR ORDINALITY,
               id_real VARCHAR2(30) PATH '.'
     )(+) y ;And is giving me the complete output.
Thanks again.

Problems with RAC and XA: Fallback

Hello,
we are seing problems with RAC and XA (Tuxedo 11, DB 11.2), specifically encountering "ORA-24798: cannot resume the distributed transaction branch on another instance".
The first scenario relates to fallback after a RAC node failure. There are two servers, S1 and S2. S1 makes an ATMI call to S2. Both servers are in the same Tuxedo group, using TMS_ORA. RAC is set up for failover (BASIC), no load balancing.
The sequence is:
- S1 and S2 are connected to the same RAC node n1. All is well.
- RAC node n1 fails. S1, S2 and the TMS_ORA all fail over to RAC node n2. After the failover has happened, all is well.
- RAC node n1 recovers. All is still well (as there is no automatic fallback).
- S1 (or S2) is restarted (either intentionally or because of a crash). Since n1 is up again, S1 connects to n1. Now we get ORA-24798. Permanently.
S1 is connected to n1 and S2 is connected to n2. Since both are in the same group, both use the same XA transaction branch. When called, S2 attempts to JOIN the transaction branch that S1 started. But the DB (11.2) does not allow the same branch to span more than one node. Hence the ORA-24798.
This seems to be a severe limitation in the combination of Tuxedo, XA and RAC. It basically means we still have to use DTP services, even with Tuxedo 11 and DB 11.2. Or are we missing something?
We could put S1 and S2 into different groups, but that seems to be inefficient, and not practical for a real application (10s of servers).
I am extrapolating from this that RAC load balancing would also not work, as S1 and S2 could be connected to different RAC nodes.

Roger,
When using an external transaction manager such as Tuxedo you should still declare Oracle services as DTP services when using Oracle Database 11g. The Tuxedo documentation is not clear about this. The relevant 11gR2 RAC documentation is at http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/hafeats.htm and states
"An XA transaction can span Oracle RAC instances by default, allowing any application that uses the Oracle XA library to take full advantage of the Oracle RAC environment to enhance the availability and scalability of the application.
"GTXn background processes support global (XA) transactions in an Oracle RAC environment. The GLOBAL_TXN_PROCESSES initialization parameter, which is set to 1 by default, specifies the initial number of GTXn background processes for each Oracle RAC instance. Use the default value for this parameter clusterwide to allow distributed transactions to span multiple Oracle RAC instances. Using the default value allows the units of work performed across these Oracle RAC instances to share resources and act as a single transaction (that is, the units of work are tightly coupled). It also allows 2PC requests to be sent to any node in the cluster.
"Before Release 11.1, the way to achieve tight coupling in Oracle RAC was to use Distributed Transaction Processing (DTP) services, that is, services whose cardinality (one) ensured that all tightly-coupled branches landed on the same instance—regardless of whether load balancing was enabled. Tightly coupled XA transactions no longer require the special type of singleton services to be deployed on Oracle RAC databases if the XA application does not join or resume XA transaction branches. XA transactions are transparently supported on Oracle RAC databases with any type of service configuration.
A"n external transaction manager, such as Oracle Services for Microsoft Transaction Server (OraMTS), coordinates DTP/XA transactions. However, an internal Oracle transaction manager coordinates distributed SQL transactions. Both DTP/XA and distributed SQL transactions must use the DTP service in Oracle RAC."
This issue came up earlier this year in another newsgroup thread at https://forums.oracle.com/forums/thread.jspa?threadID=2165803
