Oracle AS 9.0.4 and ojdbc14 - 4k blob issue

Greetings,
Perhaps someone has faced this issue before and could offer some help..
I'm trying to insert a blob (>4k) into an Oracle 10g database. To verify that
it is an oracle-specific issue that I am having, I've tried with the following
configurations:
AppServer1: Tomcat 4.1.31
AppServer2: Oracle Application Server 10g (9.0.4.0.0) for Microsoft Windows
Database1: MySql 4.1
Database2: Oracle 10g version 10.2.0
The oracle DB driver I'm using is ojdbc14.jar (a 10g download that apparently
solves the >4k problem)
The blob-insertion works when I use the same code on:
-AppServer1 with Database1
-AppServer1 with Database2
-AppServer2 with Database1
But not when I use the code on
-AppServer2 with Databse2
Now, this probably looks a bit strange because here I am trying to use 2
Oracle products together to perform a seemingly simple task yet instead
I am getting SQL (ORA-1460) exceptions when I try to do it.
Based on the above, the problem has to be the driver right? With this in mind
I've tried the following:
-bundled the ojdbc14.jar file in WEB-INF/lib
-placed odjbc14.jar in the j2ee/home/applib folder
-added a -Djava.library.path=$ORACLE_HOME/j2ee/home/applib/ojdbc14.jar to the
JVM args for the oc4j instance
but none of the above have worked.
Then I read that there is a directive in the orion-web.xml that should get the app
server to load from the WEB-INF/lib directory first. So I tried it my app wouldn't
even start. I also tried the -Xbootclasspath stuff but that has never worked for me.
I can see in the jdbc/lib directory of the Oracle app server installation that there
are some older versions of the drivers. Is it possible that these are getting loaded
first by the app server and are being used globally? If so, is there any way that they
can be overwritten / overridden?
Any advice on this would be appreciated. I hope I've been clear, many thanks,
dan

Hey Jos,
Thanks for the info. I tried bundling the 10g drivers (classes12.jar) with the webapp in
WEB-INF/lib but unfortunately there was no change. As an experiment, I dropped in
these jars into the OraHome1/jdbc/lib directory and it worked! Unfortunately, I'm not sure
if I'm going to be able to do this in a production environment, since I don't know how it will
impact on other apps that I have no contol over sitting in the same container :(
Anyone know of problems upgrading the OraHome/jdbc/lib drivers with later versions?
Am I being over-ambitious by expecting this to be acceptable - last I heard the drivers
were certified backwards-compatible so in theory there shouldn't be a problem doing
this. But hey, I'm rediscovering the meaning of the word naive since I started working with
oracle products ;-)
Cheers,
dan

Oracle: slow performance with SELECT using ojdbc14 and connection pooling

Hello,
i'm working hard the last days to solve a performance problem with our customer using a oracle 10g database. For testing I used our oracle 9.2.0.1.0 database which shows the same symptoms. All doing solved nothing: the performance while using this oracle is much slower than other databases. This result I cannot trust and so I need some advice. What is missing to improve the performance on the java side?
The webapplication I use runs fast on MySQL 4.x and SQLServer 2000, but on the above mentioned Oracle it was always 4 times slower. The webapplication uses a lot of simple SELECT-Statements without complicated joins and so on (because it should run on many different databases). Doing some days of creating tests within this webapplication, I was not able to find any entrance point for a change. All databases server I'm using, having only the default configurations after a common installation.
To reduce the complexity I wrote a simple java application with connection pooling using only the latest libraries from apache-commons(dbcp, pool), and the latest ojdbc14 for oracle 9.2.
First the results than the code: MySQL needed less than 1000 millisecond, SQLServer around 1000 milliseconds and Oracle over 2000 milliseconds. I stopped pooling and the results are for Oracle even worse: over 18000 milliseconds (mysql:2500, sqlserver:4100).
I changed the classes for Oracle and used the class oracle.jdbc.pool.OracleConnectionCacheImpl from the ojdbc14-library. No difference (around 100 milliseconds more or less).
The only Select-Statement works on this table, which has one index on HICTGID.
It contains 259 entrances.:
CREATE TABLE HIERARCHYCATEGORY (
HICTGID                 NUMBER (19)   NOT NULL,
HICTGLEVEL              NUMBER (10)   NOT NULL,
HICTGEXTID              NUMBER (19)   NOT NULL,
HICTGEXTPARENTID        NUMBER (19)   NOT NULL,
HICTGNAME               VARCHAR2(255) NOT NULL
);The application simply loops through this table using
SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?, but I always open a connection before this query and closes this connection afterwards. So I use the pooling as much as possible. That's all SQL I'm using.
    protected static DataSource setupDataSource(String sDriver, String sUrl, String sUser, String sPwd) throws SQLException {
        BasicDataSource ds = new BasicDataSource();
        ds.setDriverClassName(sDriver);
        ds.setUsername(sUser);
        ds.setPassword(sPwd);
        ds.setUrl(sUrl);
        // The maximum number of active connections:
        ds.setMaxActive(3);
        // The maximum number of active connections that can remain idle in the pool,
        // without extra ones being released, or zero for no limit:
        ds.setMaxIdle(3);
        // The maximum number of milliseconds that the pool will wait (when there are no available connections)
        // for a connection to be returned before throwing an exception, or -1 to wait indefinitely:
        ds.setMaxWait(3000);
        return ds;
    }I can switch by using external properties between three databases (oracle, mysql and sqlserver) and if I want I can switch pooling off. And all actions I'm interested are logged by Log4J.

A few comments.
There is of course another difference between your test cases then just the database. There is also the driver. And I suspect that in at least the case with the jtds driver it is helping you along where you are doing something silly and the Oracle driver is not.
Before I explain the next part I would say the speed differences between MS-SQL and MySQL look about right I think you are aiming here for MS-SQL level performance not MySQL. (For a bunch of reasons MySQL is inherently faster but there are MANY drawbacks as well which have been well discussed on previous threads)
Here is where I believe your problem lies
while (lNextBottom <= lNextCeiling) {
                 con = getConnection();
                 innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
                 innerSelStmt.setLong(1, lNextBottom);
                 rsInner = innerSelStmt.executeQuery();
                 if ((rsInner != null) && (rsInner.next())) {
                     sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
                      if (log.isDebugEnabled()) {
                           log.debug("Inner Statement: " + rsInner.getLong(1) + "\r");
                 rsInner.close();
                 con.close();
                 lNextBottom++;
             }There at least four things that are wrong with above.
1) Why are you preparing the statement INSIDE the loop. Let us for a moment say that the loop will spin 100 times. That means that you are preparing the same statement 100 times. This is bad. It is also very relevant because for example the Jtds driver is going to be caching the prepared statements you make so that actually while you try and prepare it 100 times it only actually does it once... but in Oracle I don't know what it is doing for sure but if it is preparing on each pass well than that bit of it is going take 100 times longer then it should.
2) You are opening and closing the connection on each pass through the loop... also a terrible idea. You need to fix this first so that you can repeatedly use the same prepared statement.
3) Why are you looping in the first place? More on this later.
4) Where do you close the PreparedStatement? It doesn't look like you do.
Okay so for starters your loop should look a lot more like this...
code]
con = getConnection();
innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
while (lNextBottom <= lNextCeiling) {
innerSelStmt.setLong(1, lNextBottom);
rsInner = innerSelStmt.executeQuery();
if ((rsInner != null) && (rsInner.next())) {
sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
rsInner.close();
lNextBottom++;
innerSelStmt.close();
con.close();
I think the code above (and you can put your debug stuff back if you want) which uses ONE connection and ONE prepared Statement will improve your performance dramatically.
The other question though I would as is why in the hell you are doing 100 or whatever number of queries anyway. This can be done all in ONE query which again will improve performance.
Your query and such should look like this I think.
String sql = "SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID >=? AND HICTGID<=?";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setLong(1,lNextBottom );
ps.setLong(2,lNextCeiling);
ResultSet rs = ps.executeQuery();
while(rs.next()){
// your appending to string buffer code goes here
}and I can't understand why you're not doing that in the first place.

Xdb.jar and ojdbc14.jar incompatibility ( XMLType.createXML() ) ??

I am using the latest xdb.jar (from xdk_java_9_2_0_5_0.zip) and ojdbc14.jar
and it appears that xdb.jar calls a method that does not exist in ojdbc14.jar.
It happens when executing
OPAQUE opaque = rset.getOPAQUE("value");
XMLType xt = XMLType.createXML(opaque); // <-- here
The exact error message is:
java.lang.NoSuchMethodError: oracle.jdbc.internal.OracleConnection.getProtocolType()Ljava/lang/String;
     at oracle.xdb.XMLType.initConn(XMLType.java:2072)
     at oracle.xdb.XMLType.<init>(XMLType.java:903)
     at oracle.xdb.XMLType.createXML(XMLType.java:493)

Hi,
There are known problems with xdb.jat that is bundled with XDK 9205.
As a workaround, you need to use an older version of xdb.jar from either XDK-9.2.0.3 or XDK-9.2.0.4 since the mentioned exception is generally thrown due to problems in xdb.jar that comes with XDK-9205.
If you do not have any of these versions of XDK, you could use the xdb.jar that comes with the database 9.2.0.3. The xdb.jar is present in <oracle_home>/rdbms/jlib folder.
Hope that helps.

Oracle EBusiness suite professions tasks and duties

Hello everybody
I inquire about something regarding Oracle EBusiness suite professions tasks and duties. I've tasked by my manager with writing a report lists the main tasks and key responsibilities for each of the following technical professions within Oracle E Business Environment:
1)-Apps DBA.
2)-Apps Technical Consultant (Apps Developer)
3)-Apps Business Consultant.
I've contacted Oracle Support recently via opening SR .But, They informed me that they don’t provide such information and therefore, they suggest me weather to contact Oracle Consulting to post here.
I would appreciate your help.

I don't see how you'd be able to integrate OAM with EBS unless you have the oSSO (assuming of course that you're not on the bleeding edge, per 975182.1).
We are running the same configuration and have setup the redirects in OAM policy. We setup specific context roots for each application, then use OAM policy to redirect. (for example, http://iwa-server/ebs redirects to https://ebs-server)
Unique authorization rule for each redirect, then a unique "policy" on the "Policies" tab for each redirect. Each Policy maps to the respective Authorization Rule.

Can i use "Oracle Database 12c: Performance Management and Tuning " training for getting certification on "Oracle Database 11g: Performance Tuning 1Z0-054"

i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?

I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts.

Oracle EBS 12.1.3 and SOA 10g hardware sizing

Hi All,
To give you the background, we have integration requirements where in one of the interface about 20000 sales orders come in the system everyday and they have about 3-5 lines per sales order. Most of these orders come between 3-6 PM. We have 50 other interfaces along with this but this is a major one. Client is concerned about performance and so we have to give right design and right hardware sizing so that the system is able to handle all the load without causing performance issues. We are planing to use Oracle EBS 12.1.3 and SOA Suite 10.1.3.5 (10g)
Any processes, documentation on how to go about hardware sizing, tools will be helpful
Thanks,
Rahul

Oracle Workflow Manager, Agent Listener, and Java Mailer problem

Hi,
I am not sure this topic to this forum, since this might be installation issue.
But I am hitting a big wall.
I had Windows 2000 SP4.
I have already installed Oracle Database 10gR1, Oracle Developer 10gR2, and Oracle Workflow 2.6.3 Standalone previously.
Including :
- Oracle Workflow Server 2.6.3
- Oracle Workflow Builder 2.6.3.5
- Apache HTTP Server 9.0.4
- Workflow Middle Tier
Anything seems to right, including the Notification Mailer and the Business Event.
And I had also made backup of them surely.
Now,
I'd like to change into Oracle Database 10gR2 because :
1. Some errors I found when I tried to call a Report from Oracle Form.
Unable to connect to Report Server ...
I thought Oracle Database 10gR1 is not suitable for Oracle Developer 10gR2.
2. And in the OWF 2.6.3 Workflow Home Page, there was no Logout button (which I found in OWF 2.6.4)
I removed my previous installation including Oracle Workflow.
After strugglineg in the installation of Oracle Database 10gR2, now I am facing another problem with Oracle Workflow.
I succesfully installed Oracle Workflow 2.6.4 Server and Oracle Workflow Manager (standalone version),
and the Oracle Workflow Middle Tier.
After I launch Oracle Workflow Configuration Assisstant, everthing seems to be normal.
I succed to open the Oracle Workflow Home Page (and found the Logout button there)
Next, I tried to navigate to the Oracle Workflow Manager.
1. I start the OC4J_Workflow_Management_Container --> initialized
2. OC4J_Workflow_Component_Container
The following error line appeared in the OC4J command prompt
06/05/26 10:31:40 LOG_ID_UNKNOWN : oracle.apps.fnd.cp.gsc.Logger.Logger(String,
int) : Logging to System.out until necessary parameters are retrieved for Logger

06/05/26 10:33:57 Oracle Application Server Containers for J2EE 10g (9.0.4.1.0)
initialized
3. finally it initialized
Next I tried to go to Oracle Workflow Manager from related link of Enterprise Manager
It is said that the OWF_MGR is locked
(I surprised since I had UNLOCKED the OWF_MGR after the installation and succeed to login at the Workflow Home Page)
And the following error line appeared in the commaned prompt after that
06/05/26 10:35:03 OrionCMTConnection not closed, check your code!
06/05/26 10:35:03 Logical connection not closed, check your code!
06/05/26 10:35:03 (Use -Djdbc.connection.debug=true to find out where the leaked
connection was created)
4. I re-UNLOCK the OWF_MGR and login to Oracle Workflow Manager
I noticed that the Agent Listener and Notification Service is Unavailable
(In OWF 2.6.3, The Agent Listener was started and Notification Service was waiting to be configured)
I tried to start one of the Agent Listener, but the following error appeared
ERROR: The Service Component Container is not running
Well, I had the same problem when installing the OWF 2.6.3
I tried to uninstall (remove) and re-install it like I had done before in OWF 2.6.3
(based on someone's post in Oracle's forum)
But this time, the re-installation won't fix this problem. (It was succeed in the OWF 2.6.3)
Everytime I start the OC4J, using wfmgrstart.bat and wfsvcstart.bat
the OWF_MGR is re-LOCKED(TIME) automatically.
And the servlet (WFALSNRSVC and WFMLRSVC) are not running.
I am worry, since I cannot use the Notification Mailer if this problem had not fixed yet.
(In OWF 2.6.3, the mailer was not available until those servlet is Started)
Sorry for the long post.
Any help would be grateful.
Many thanks,
Buntoro

Hi,
Finally, I have found the solution.
Step :
1. Start all of the Oracle Service, except for the OC4J
If you have already started OC4J, then stop them
Unlocked the <wf_manager_user>
2. Search in your Oracle Home : data-sources.xml
There should be two files,
one is in the ...\OC4J_Workflow_Component_Container\application-deployments\WFALSNRSVCApp
the other is in ...\OC4J_Workflow_Component_Container\application-deployments\WFMLRSVCApp
3. Make sure, you create back up of them.
4. Replace the following line
password="->pwForOwfMgr"
with
password="<your_wf_manager_password>",
should be look like this
password="a"
5. Now start the OC4J using wfmgrstart.bat and wfsvcstart.bat
6. Next, login to the Oracle Workflow Manager
This worked for me.

Oracle Open World in SanFrancisco and Oracle Spatial

Hi,
This week is Oracle Open World in San Francisco, and while usually we try to keep this message board strictly technical, I wanted to mention that there are some interesting things happening here.
There are a few sessions Wednesday in Room 2016 starting at 3:00 pm:
Data Management on a Budget with Oracle 10g: Exploring Strategies and Tactics with the U.S. Geological Survey
by Nate Booth and Harold House, USGS
Oracle Database 10g Spatial Performance and Manageability Best Practices and German Rail Case Study
by Dan Abugov (me) and Andreas Hoefler, Fichtner Consulting & IT AG
I'm excited to be talking about Partitioning Best Practices, and we'll be posting the white paper here on OTN.
Finally, please come and see us at booth E28 in the Oracle DemoGrounds (we have Locator/Spatial, MapViewer, and Workspace Manager here in the pod). If you are the FIRST person to mention reading this posting on OTN when you visit the booth, we'll be happy to give you a copy of "Pro Oracle Spatial", the first book devoted to developing applications using Oracle Spatial. The book was written by Ravi Kothuri, Albert Godfrind (two Oracle Spatial Developers) and Euro Beinat of Geodan NL. One of the authors (Albert Godfrind) is here, and if you ask I'd bet he'd autograph it for you!
We also have a very limited supply of the book we'll be giving out over the course of the conference.
Of course, everyone who stops by will get the Oracle Spatial mini CD which includes viewlets, white papers, and more.
The book is also available here:

Hello,
Take a look at this page, http://www.oracle.com/technology/events/oracle-openworld-2007/index.html
There are links here to the whole OOW (social network,twitter,blog/flicker)osphere I think the new buzzword being "Social Graph" that covers all that.
But anyway there are tons of ways for people to sign up and track the sessions and see who's going to go where, etc.
Regards,
Carl

Oracle 11g R2, CREATE TABLE and QUOTAS

Hello everyone,
I need some insight about a strange behavior I found out in Oracle 11gR2. Don't know if I do miss something or if I just found out a security issue with Oracle.
Oracle Version : 11.2.0.1.0
The problem is related with the CREATE TABLE privilege and the QUOTA on specific tablespace.
Please, try this on your systems (if you have some spare time and care to confirm the "bug").
Create a user, grant only two privileges, CREATE SESSION and CREATE TABLE.
Grant NO quota on any tablespace.
Try to create table on any tablespace (except SYSTEM) and tell everyone if it worked or not.
The oracle documentation states the following :
To create a relational table in your own schema, you must have the CREATE TABLE system privilege. To create a table in another user's schema, you must have the CREATE ANY TABLE system privilege. Also, the owner of the schema to contain the table must have either space quota on the tablespace to contain the table or the UNLIMITED TABLESPACE system privilege.
[http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/statements_7002.htm#SQLRF01402]
The fact is, so far, on two different instances of Oracle 11gR2, my users are not limited in creating tables only where they have quotas but wherever they want except SYSTEM.
The correct behavior would be to deny the table creation on tablespace where there is no quota but it does not.
My instance of Oracle 10g are behaving correctly and thus the table creation is denied on tablespace with no quota.
P.S1 Sorry if this a well known "bug/problem/issue". I've been ridicule on a well known forum for asking the same question. I am in no need to be "spoon filled" as stated on that famous website! I have read the documentation! I have googled a lot!
P.S2 Even though the table creation work on tablespace with no quota, you still can't insert data in it. So, big picture, the user can't filled the tablespace with irrelevant data but he can creates thousand of tables...!
Do I miss something?
Is there any "default" option I have to flag to prevent table creation where it should not?
?(?)

Hi. I'm planning on taking my OCP exam. If the exam ask a question realted to this topic, what is the correct answer?
create user barry identified barry
grant create session, create table to barry
1) barry cannot create a table since he has no quota
2) barry can create a table
According to the oracle document, the barry needs quota on the tablespace to create a table. however, according to the link you provided, in 11gR2, barry does not need quota to create a table. He only needs a quota to insert data.

Impdp ORA-02421 on Oracle 10.2.0.1 and 10.2.0.2

Hello,
The impdp utility crashes the import process with ORA-02421 for a schema which starts with a number on both Oracle RDBMS versions : Oracle 10.2.0.1 and 10.2.0.2.

Eg.
Processing object type SCHEMA_EXPORT/PROCEDURE/PROCEDURE
ORA-39126: Worker unexpected fatal error in KUPW$WORKER.PUT_DDL [PROCEDURE:"[b]233"."ADD_JOB_HISTORY"]
ORA-02421: missing or invalid schema authorization identifier
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPW$WORKER", line 6273
----- PL/SQL Call Stack -----
I need to migrate 1400 schemas (with passwords and all objects) witch starts with a number and I cant rename them.
Is there a workarround to do this staff.
Thank you
Best regards,
Max

Diffrence in running oracle on 32 bit OS and 64 bit OS ?

Hi ,
I am new to oracle , i would like to know what's the diffrence running oracle under 32 bit OS and 64 bit OS

i would like to know what's the diffrence running oracle under 32 bit OS and 64 bit OSWhat type of differences are you looking for? Basic one being you run 32 bit version of Oracle under 32 bit OS and 64 bit version under 64 bit OS.
Other being the availability of addressable memory in 32 and 64 bit versions (but that is more of an hardware level issue).

Differences beetwen Oracle AS 10g Release 2 and Release 3

Hi
Could you give me links or just write about differences between Oracle AS 10g Release 2 and Release 3. I have books to Oracle 10g AS Release 2, and I don't know, what information are incorrect with reference to Release 3. I've found this link http://download.oracle.com/docs/cd/B32110_01/core.1013/b32196/whatsnew.htm#sthref7 , but Oracle 10g AS Release 3 for example does not require a metadata repository. So where can I find all diferences?
Thanks awfully for help.

Application Server 10R2 (10.1.2.0.2) includes products such as OID, Forms & Reports, Discoverer, Oracle Portal etc. These are not included in Application Server 10R3, which was a JEE only install geared towards JEE solutions.
Both versions will be desupported in December 2011 so I would spend to much time on these versions. Go with Fusion Middleware 11g : http://download.oracle.com/docs/cd/E21764_01/index.htm
