Manually Migrating from Oracle 10g to 11g

Hello, I'm currently a student in an Oracle DBA class. I'm totally new to the Oracle world.
One of our final assignments concerns upgrading Oracle instances without the use of DBUA.
I've currently got Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 and am trying to upgrade to 11.1.0.7.0
This is all inside of VirtualBox, running Windows Server 2008. I've been using 10g with absolutely no issues for the duration of this class.
I successfully installed 11g, choosing to install the software only and not use dbua.
I changed my environment variables to point towards the 10g installation; ORACLE_HOME, ORACLE_SID, PATH, and LD_LIBRARY_PATH.
Then logged into 10g's SQLPlus and ran utlu111i.sql, which ran successfully. I issued a shutdown immediate and exited SQLPlus.
Changed my environment variables to point towards the 11g home and set ORACLE_SID as the 10g database name. I was able to log into 11g's SQL plus, was told I was connected to an idle instance, which I expected. I issued a startup upgrade command, and then attempted to run catupgrd.sql, but got an error stating that I had to run the script from 11g.
If I don't set the environment variables then when I try to log into 11g's sqlplus, I get an ORA-12560: TNS:protocol adapter error... I've tried reinstalling 11g from scratch, but to no avail. My instructor and I have been emailing back and forth frequently over the past few days but we have not been able to reach a solution, so I thought I would see if I could pick your brains.
Here's all of the terminal output from the process:

Database migrated from Oracle 10g to 11g Discoverer report performance issu

Hi All,
We are now getting issue in Discoverer Report performance as the report is keep on running when database got upgrade from 10g to 11g.
In database 10g the report is working fine but the same report is not working fine in 11g.
The query i have changed as I have passed the date format TO_CHAR("DD-MON-YYYY" and removed the NVL & TRUNC function from the existing query.
The report is now working fine in Database 11g backhand but when I am using the same query in Discoverer it is not working and report is keep on running.
Please advise.
Regards,

Pl post exact OS, database and Discoverer versions. After the upgrade, have statistics been updated ? Have you traced the Discoverer query to determine where the performance issue is ?

Row chaining and row migration in Oracle 10g R2/11g R2

Hi,
Due to the business rule changes, one of the numeric column in a large table (20 millions rows) will be expanded from number(8) to number(10). Also, the values of this column of each row will be updated from 6 digits to 10 digits. All the indexes that use this column will be dropped and recreated after update. I would like to know if there is any row chaining or row migration issue in Oracle 10g R2 /11g R2.
Thanks for your help

EPMMaster.rpd Fusion Pack migration from OBIEE 10g to 11g

We have successfully installed OBIEE 10g and 11g on Windows 2008 32bit servers. On the 10g Installation, we have applied the Fusion Pack EPMMaster RPD file and it connects successfully to our EPM warehouse. We want to migrate the Fusion pack to 11g which is also setup on the same platform. Per the instructions in the documentation, we have copied the files (RPD file and Webcat folder) to the 11g server. We run the UA.bat file and it proceeds to start copying the files over fom the RPD and WebCatalog to the new system. It completes this process, but then hangs on starting the Oracle BI server - it never gets beyond that.
We will be purchasing the EPMMaster RPD and know it is not available yet for 11g – however we’re trying to get ahead of the curve a bit and manually fix the items in the presentation layer that will not render correctly in 11g
upgrade exception occurred
Unable to start process: instance1: coreapplication_obis1
One thing that I noticed – Since the UA tool does not completely finish --
RPD size on 10g – 42,675KB; 11g – 6,375KB
I manually change the webcat in Enterprise Manager to the EPMMaster catalog -this actually caused additional errors on restart.
Has anyone attempted upgrading a delivered RPD to 11g?
Thanks in advance -

This is a known issue that we have worked through with Oracle tech support. The Dimension Deduction.Deduction Sid causes an error that prevents the UA tool from completing the upgrade process. There are a couple of ways around this, but the fastest is to simply delete the Dimension, the two related hierarchies and the fact table that is joined to this dimension. Physical table do not need to be touched however. There are still issues once it’s moved to 11g, but those can be addressed post migration. Thanks much to the Oracle support team for helping us out with this issue!

Challenge question and password migration from oimm 10g to 11g r2

hi all,
can you please tell me how do i do the migration of oim 10g user's password and challenge questions to oim 11g r2. Do we have any api to do it. these values are in encrypted format in oim db.
thanks

Run your sql query to output the encrypted fields to a flatfile or csv, and include the usr_login field so you know which user to assign the values to.
Copy your config folder from your oim server and create a patch like c:\xellerate\config. In your code, when you connect to OIM, use this:
System.setProperty("XL.HomeDir", "c:/xellerate");
System.setProperty("java.security.auth.login.config", "c:/xellerate/config/authwl.conf");
Now, when you read the file and have the encrypted field, use this code:
String decryptValue= tcCryptoUtil.decrypt(encryptValue, "DBSecretKey");
Now that you have the unencrypted value from your 9x instance, you can use the APIs to set challenge questions, and set user passwords with the 11g APIs.

How to migrate Spatial SDE from 9.3 to 10 and Oracle 10g to 11g

Hi,
I would like ti post a question to ask a help.
We have a task of migrating from Oracle 10g to 11g and at the same time from ArcGis 9.3 to version 10; SDE to SDO but no experience in this type of work.
We are looking for any information that may help us understand what is the best strategy to complete the activity.
Any help is very appreciated.
Thanks in advance.

Hello unnamed user8111502,
In general you want to post your ArcSDE question to the ESRI forums at
http://forums.arcgis.com/forums/32-Geodatabase-amp-ArcSDE
But if you want some advice then I would suggest doing the Oracle upgrade first and the SDE upgrade second - for no other reason than this is what I did and had no problems.
Upgrading Oracle from 10g to 11g is pretty straightforward, there is nothing "special" you need to do as regards your SDE middleware. Just do the 11g upgrade and then upgrade SDE to the 9.3.1 11g version (again not a big deal).
You did not mention the storage type you are using. If you are using SDO_GEOMETRY, then one thing I did notice is the 11g upgrade process will drop and rebuild all your spatial indexes so if you have an huge amount of SDO spatial data on an underpowered machine then your upgrade person should bring a book along as it can take some time.
Upgrading SDE from 9.3.1 to 10 is similarly pretty straightforward. ESRI has made extensive changes to their SDE schema data model but their underlying storage types and indexes and such have not changed. So there is no change to the data itself that I know of. The important thing is that all the ESRI users of your database need to upgrade to version 10 as well. Anyone still on a 9.3 client - this includes desktop users and servers (AGS, IMS) will no longer be able to use the database after the upgrade. As version 10 is backwards compatible with 9.3 it would make sense to have all your clients upgrade to 10 first (and troubleshoot any issues with this) and then do SDE last.
Cheers and good luck,
Paul

MIgration from Oracle 9.2.4.0 to Oracle 10g Release 2 (10.2.0.1.0)

Hello
We are planning to upgrade and migrate from Oracle 9 to Oracle 10. ( both version on windows)
Would be of great help if I could avail the below information.
Most of the Instance are more than 50 gig
1 Should use a EXP / IMP or Should use DBUA ( prefer a safe method )
2.IF DBUA used any idea how much time it should take .
3.Any other method for upgrade.
We are currently in an analysis phase , we do have some instance that are already 10g but were created from scratch.
Thanks for all your help in advance
Cheers

Most of the Instance are more than 50 gig
1 Should use a EXP / IMP or Should use DBUA ( prefer
a safe method )Use DBUA , it is safer then exp/imp
2.IF DBUA used any idea how much time it should take
It depend on database , machine etc. it should not take more then 2-3 Hr
3.Any other method for upgrade.
I always use manual method and feel manual upgrade is safest.

Migration from Oracle 9i database to 10g in ECC5

Hi Experts,
We are planning to move our production system which is currently running ECC5 on AIX OS and Oracle 9i database to AIX OS and Oracle 10g database.
Some doubts regarding the above procedure:
1)Is there any possibility of SAP system migration from Oracle 9i to Oracle 10g. If yes, do we need to perform any addinitional steps for that?
2)If the above condition is OK, then what type of system copy should we need to follow: Homogeneous or Heterogeneous? Heterogeneous system copy is ususally done incase of system copy involving different databases. Does that apply for differnt versions too like Oracle 9i and 10g?
Any response is highly appreciated.
Regards,
Sanjay

If i'm using the dbua then the above issue will be solved by dbua itself?Well, DBUA will only perform a sanity check on your current release and if it doesn't pass it will fail. In other words DBUA will not upgrade your 9i release to the proper compatible release that you have to do before upgrading to 10R2.
Personally I never used DBUA, I always prefer manual upgrades, DBUA is good for you bcz it will not allow you to miss any step while upgrading.
What is the size of the database which you are going to upgrade?

What are the Issues in Migration from oracle 8i to oracle 10g

Hi,
Can you let me know what are the issues that i face when i migrate from oracle 8i to oracle 10g. I will be very thankful if you give me a list of issues that you face while migrating from 8i to 10g

In addition to Max's reply, you must be aware that you have to test your applications agains 10g database before you actually upgrade the database.
If you use CBO, it may produce different execution plans for one query when you run it in 8i and 10g. This may affect your application performances, which you don't like to happen.
Also you have to decide how much downtime you can afford during the migration. Can you afford some downtime and how much? If you can't than this makes the situation more complicated.
How big is your database? You may end up only with simple export/import solution using export import utility.
The bottom line is, whatever you decide, you must test your applications running against 10g database before you actually upgrade your database.

Porting from Oracle 10g AS to Oracle 11g Weblogic server

Hi,
I am trying to port J2EE applicatin from Oracle 10g AS to Oracle 11g Weblogic Server. I have jsp files which contains sql code embedded to fetch data from the DB. The components used in this application are Java, JSP, Servlets and Stateless session beans.
I have a commonjar which is used to create DB Connection manager and other common stuff which is present inside web-inf/lib. My application is packaged as an ear and which contains the war and different ejb-project.jar files. When the Stateless bean is trying to call the ConnectionManager class, which is present inside the commonjar inside web-inf/lib, I get InvocationTargetException. When I debugged in Eclipse, I see that that inside ejb the reference ConnectionManager, the variable cannot be resolved. So I guess at runtime, ejb is not able to locate ConnectionManager Class.
I tried to copy this jar to APP-INF/lib and the same jar is present inside web-inf/lib as well. In that case what happens is the jsp fails with the exception ConnectionManager cannot be resolved.
How can I make the ejb work by keeping the commonjar inside web-inf/lib alone.
Any help or suggestions?
Thanks
Raj

The classloader hierarchy in WLS looks like this (arrows denote inheritance direction):
Java bootstrap classloader <- Java CLASSPATH classloader <- WLS $DOMAIN_HOME/lib classloader <- Application (e.g., EAR) classloader <- web app classloader <- single JSP classloader
The Connection Manager is loaded by the web app classloader while the EJBs are loaded by the application classloader so the EJBs have no visibility to the classes loaded by the child (web app) classloader.
The simplest fix might be to move the Connection Manager jar file to the EAR file's APP-INF/lib directory.
One word of caution though, you need to be using WebLogic Server's Data Sources and JDBC connection pooling to make sure that you correct transactional behavior if the application is doing any sort of JTA transaction (regardless of whether the JTA transactions are using XA or not...).
Hope this helps,
Robert

How to migrate a table from ORACLE 10g to 8i

have table named 'liuxg_tab_01' in 10g.
This morning I exported this table using 'exp' and then tried to imp it into 8i, I failed.
After a while, I created a database link named 'ctf' in 8i which connected to 10g. I issued 'create table test as selct * from liuxg_tab_01@ctf',it returns 'ORA-01723'.
Then I extraced the DDL of 'liuxg_tab_01' from 10g with QUEST TAOD, it's:
CREATE TABLE LIUXG_TAB_01
OWNER VARCHAR2(30 BYTE),
OBJECT_NAME VARCHAR2(30 BYTE),
SUBOBJECT_NAME VARCHAR2(30 BYTE),
OBJECT_ID NUMBER,
DATA_OBJECT_ID NUMBER,
OBJECT_TYPE VARCHAR2(19 BYTE),
CREATED DATE,
LAST_DDL_TIME DATE,
TIMESTAMP VARCHAR2(19 BYTE),
STATUS VARCHAR2(7 BYTE),
TEMPORARY VARCHAR2(1 BYTE),
GENERATED VARCHAR2(1 BYTE),
SECONDARY VARCHAR2(1 BYTE)
But I can not create a table using the upper DDL in 8i if I do not wipe off those "BYTES".
After creation of the table using the upper DDL without those 'BYTES', I sucessfully executed 'insert into LIUXG_TAB_01 select * from liuxg_tab_01@ctf'.
Anyone has a better method to move a table from ORACLE 10g to 8i?

1) The particular version of 8i and 10g in use here would be useful. I'm not sure that Oracle supports database links between any version of 8i and any version of 10g, though, so you're probably lucky that it worked as well as it did.
10g 10.1.0.3.0 and 8i 8.1.7.0.0
2) What version of the export utility did you use? You would need to use the 8i version to generate the dump file to have any chance of working, not the 10g verion.
I use the 'exp' provided with 10g 10.1.0.3.0 and 'imp' with 8i 8.1.7.0.0. I have tried to export data directly from 10g 10.1.0.3.0 using 'exp' provided with 8i 8.1.7.0.0. Failed.
3) Why? Since 8i is desupported, there isn't a lot of call for tools to move data from supported releases to unsupported releases.
We have an 8i DB which is still porivding insentive services. We just wanna migrate some tales from 10g to it.
FYI, NLS_LENGTH_SEMANTICS was introduced in 9i, so it's no suprise that 8i objected to the BYTE keyword in the DDL.
What's FYI :P
Another option would be to generate a CSV file of the data from 10g and use SQL*Loader to load it into 8i. Not sure this would be any easier, though.

Live migration from oracle 8.0.3.0.0 to oracle 10g

Hello everyone,
I have Oracle 8.0.3.0.0 running on Windows NT platform. I wish to migrate from Oracle 8.0.3.0.0 to Oracle 10g. And I wish to do it without shutting down my Oracle 8 server. Sort of live migration. Since transaction rate is very high. And putting down the server would mean hanging up whole work. Is it possible. If yes what all hardware and software requirements are there? Or Import and Export is the only option,
In anticipation of your guidlines,
Durgesh

Durgesh,
 No, you cannot migrate directly from 8.0.3 to 10g (either 10gR1 and 10gR2). Read the upgrade guide which concern your target 10g release :
 Oracle Database Upgrade Guide 10g Release 2 (10.2)
 Oracle Database Upgrade Guide 10g Release 1 (10.1)

Upgrading from Oracle 10G standard edition to Oracle 10G enterprise edition

Hi
I want to upgrade from Oracle 10G standard edition to Oracle 10G enterprise edition. Is there any script provided by oracle which I can run on existing Oracle 10G standard edition to upgrade to enterprise edition after completing the licensing formalities or do I need to install Oracle 10g Enterprise edition from scratch and then migrate my data.
Ramanbir S

You will not need to perform any data migration to upgrade to EE. The diffetence between standard en enerprise editions are the features offered. When you upgrade you can use the same set of files you used to install standard edition and just add the enterprise edition features you want to use in the 'Custom' section of the Universal Installer.

Installing oracle 10g and 11g client on the same Linux RHEL 5.4 host

Is it possible to install Oracle 10g and 11g client on the same Linux RHEL 5.4 host and have the application switch between 10g and 11g? and how would the 10g and 11g be installed?

Thanks for your reply.
Typeically if 10g is installed in /home/roacle/product/10.2.0, are you saying that for 11g, it would be /home/oracle/product/11.0.0 ?
How about switching the application? Does changing the ORACLE_HOME and PATH environment variable setting enough ? Let's say from
ORACLE_HOME=/home/oracle/product/10.2.0/client_1 to /home/oracle/product/11.0.0/client_1
