10g-11g migration

Hi!
I have an existing webcenter application, using portlets, that I want to migrate to 11g using task flows. Is there a guide on how to do this properly, or do I have to restart from scratch? There does not seem to be an awful lot of information available...
Regards,
Jeroen van Veldhuizen

Hi,
WebCenter is not yet part of JDeveloper 11. This is planned for early next year. Migration is possible if you strip out the WebCenter pieces. However, there is no automated migration path to ADF Faces RC and taskflows (will require a re-design to the app). Your application will be migrated to Trinidad

Where are my database diagrams - 10g - 11g migration ???

Hi all,
Can anyone please HELP me in locating/recovering my tables in my database diagrams.
I had my tables designed in JDeveloper 10g (10.1.3.10.3984 build JDEVADF_10.1.3.1.0_NT_061009.1404.3984) and had 11g Studio 111 installed yesterday day.
When started 11g I was prompted to migrate my existing projects, I clicked yes. The migration returned with a couple of errors which I didn't quite understand.. Sorry I forgot to make a note.
Now I open my database diagrams all I have got left are the "note" items. What have happend to my tables and sequences? I went back to 10g I saw the same thing.
Is possible to recover the 10g diagrams in 10g/11g? Please advise
Thanks in advance
Hien

Hello Hien,
There is a specific forum for 11g issues (JDeveloper and OC4J 11g Technology Preview ); however, it's documented in the release notes for the 11 technology preview that migration from 10g is not supported IN THE PREVIEW.

Some questions regarding BPEL 10g to 11g migration.

Hi All
I have the following queries,
1.Is it mandatory to load xsd's , wsdl's , XREF , DVM into MDS ? or is it allright to keep them in file system ? currently we have a number of xsd's and wsdl's inside each of our 10g project > bpel subfolder. If they need to be deployed to MDS , then which files in 11g will need to be modified to use the new 'oramds:/apps/..... ' reference ?
do they get automatically loaded into MDS when a Composite is deployed on WLS or do they have to be deployed separately using ant-sca-deploy?
2. Should we modify fault-bindings.xml , DefaultPolicy.xml before or after upgrading the 10g project ? I understand that their references in composite.xml also need changing.
3.
a.Is it mandatory to modify the 10g dbadapter.rar contents (convert oc4j-ra.xml to weblogic-ra.xml ) and deploy the rar on 11g ?
b.or can we manually create data sources,outbound connection pools> jndi factories etc and redeploy the dbadapter on 11g so that its weblogic-ra.xml gets updated with the data sources,jndi that we manually created ?
want to know if 'a' and 'b' do the same thing ,so mutually exclusive OR both need to be done .
same question for JMSAdapter.rar, aqadapter.rar
4. When upgrading BPEL 10g to 11g using Jdeveloper, should all the data sources used by the project be created on Jdeveloper ?
5. Is it necessary to copy properties from 10g domain.xml t0 11g bpel-config.xml,soa-infra-config.xml ?
6. Should external webservices used by BPEL be up and running , while upgrading from 10g to 11g in jdeveloper , OR only during deployment to wls? if they are needed during upgrading how to link to them from jdeveloper ?
7. Do BPEL 11g projects needs to be deployed on WLS only as a SAR or are any other formats allowed ?
Thanks in anticipation

Oracle 10g/11g to Sql Server 2005 Migration

Dear All,
I am a beginner to this migration Activities..
We have designed one Application which is havin Database as Oracle 10g.
and We had another small Application which is having Sql Server 2005 has Database.
Daily we need to convert DB of Oracle to Sql server DB in order to acces recent updated data..
Pls help me how to convert Database in Oracle 10g/11g to Database in sqlserver 2005..

Hello,
this is an Oracle forum and we are handling here migrations from foreign databases to an Oracle database.
For migrations in the other direction, in your case from Oracle to MS SQL Server, you need to read the Microsoft pages, e.g.:
http://www.microsoft.com/sqlserver/2005/en/us/migration.aspx
Daily we need to convert DB of Oracle to Sql server DB in order to acces recent updated data..Normally a migration is not a daily process, so I guess that you just want to transfer data from Oracle to SQL Server on a daily basis. If that is the case, you should consider to use our Gateways. Please start reading here:
http://www.oracle.com/technetwork/database/gateways/index-100140.html
Using the Database Gateway for MS SQL Server (DG4MSQL) or the Database Gateway for ODBC (DG4ODBC) you can copy your data from your Oracle database to your SQL Server database, using a database link in the Oracle database.
Please let me know whether this answer helped you.

Toplink 10g to 11g migration advice.

We have application that was completely developed JDeveloper 10.1.3/4 with Toplink, JSF, ADF, and Session Facade; extremely similar to the SRDemo.
I want to upgrade to JDeveloper 11g, and will probably just let JDeveloper to automatically migrate the 10g application to 11g.
Does anyone have any tips or lessons learned concerning Toplink and/or ADF when using the 11g migration process?
Thank you.

I downloaded and installed the jdevstudio11111install.exe from the Jdeveloper download page.
While performing the migration, I received a Toplink exception (matches this thread: [TopLink exception when migrating from JDev 10.1.3.4 to 11g|http://forums.oracle.com/forums/thread.jspa?messageID=3593192&#3593192] ).
I assumed this was the bug you were referencing, was that incorrect? Did I inadvertently download the wrong version?
Studio Edition Version 11.1.1.1.0
Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407
Am I missing a patch? Can I move forward with the migration, or is this a show stopper?
Thank you.

Forms migration from 2.0 to Forms 10g/11g

Hi,
I want to migrate from forms 2.0 to 10g/11g. I know the migration path is 2.0->4.5->6i->10g/11g . I want to know is it feasible to do the migration from 2.0 to 10g/11g. what are the recommendations.
Thanks & Regards,
Noman

PITTS claim to be able to migrate forms from Forms 2.3 onwards.
http://www.pitss.com/solutions/pitsscon-solutions/forms-to-forms/
It depends on how much you want to spend...
However, if you're looking to do it yourself...
Do you have access to developer versions of Forms V3.0 or 4.5? It's easier if you go from 2.0 -> 3.0 -> 4.5/6i -> 10g. Each version has its own migration utilities, but they gradually remove support for earlier versions. Version 2 (2.3) triggers can exist in version 3, but not in later versions.
Do you have experience of Forms 6i or 10g? If not, you have the scope to re-write the application in the language of your choice. The Oracle website has a number of articles on migrating from Forms 3 and 6i, but not from earlier versions, so it depends on your current knowledge as to how you want to do.
I've migrated Forms 3.0 (with 2.3 style triggers) to 10g by hand. It requires an understanding of how Forms used to work compared to how it works now. You will basically be creating your new application from scratch (depending on what you have been able to upgrade) based on the the blocks and items of your old forms. Your task will be so much easier if you have the intermediate Forms developer tools (4.5/6i).
You'll also be upgrading your database. I assume that you are on Oracle 6/7.

How to display an image in FORM 10g/11g data recovered through Web Services

I need to show in a FORM 10g/11g an image that is recovered from a Web Service (XML format).
(The Web Service retrieves several images from SQL Server database).
versions previous 6i... one use field type ActiveX Control, and there showed the respective images, even with previous and next controls. Aspect that new versions of form 10g & 11g is obsolete.
Any help thank you.

I tried it doing it this way and it worked -
1. copy the image into the directory aliased in 9iAS configuration file as '/images/'.
2. In the PL/SQL code section after header, I write the following code -
begin
htp.p('<img src="/images/pobexp.gif"/>');
end;

Maximum Data file size in 10g,11g

DB Versions:10g, 11g
OS & versions: Aix 6.1, Sun OS 5.9, Solaris 10
This is what Oracle 11g Documentation
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/limits002.htm
says about the Maximum Data file size
Operating system dependent. Limited by maximum operating system file size;typically 2^22 or 4 MB blocksI don't understand what this 2^22 thing is.
In our AIX machine and ulimit command show
$ ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited <-------------------------------------------
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       unlimited
coredump(blocks)     unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimitedSo, this means, In AIX that both the OS and Oracle can create a data file of any Size. Right?
What about 10g, 11g DBs running on Sun OS 5.9 and Solaris 10 ? Is there any Limit on the data file size?

How do i determine maximum number of blocks for an OS?df -g would give you the block size. OS blocksize is 512 bytes on AIX.
Lets say the db_block_size is 8k. What would the maximum file size for data file in Small File tablespace and Big File tablespace be?Smallfile (traditional) Tablespaces - A smallfile tablespace is a traditional Oracle tablespace, which can contain 1022 datafiles or tempfiles, each of which can contain up to approximately 4 million (222) blocks. - 32G
A bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion ( 232 ) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks.

Oracle 10g XE migrate from 32bit to 64bit becomes slower

Oracle 10g XE migrate from 32bit to 64bit becomes slower
Currently we have a database using Oracle 10g XE R2
(Oracle Database 10g Express Edition Release 10.2.0.1.0)
on a linux 32bit server.
And recently we did migrate it to another 64bit linux server.
But found after migration is it running slower at 64bit server (~ 25% slower)
1. We would wonder any tuning is required on 64bit server?
Besides, as I know Oracle XE only using single core CPU for processing.
On 32bit linux the CPU is Intel(R) Xeon(R) CPU E31235 @ 3.20GHz
On 64bit linux the CPU is Intel(R) Xeon(R) CPU E5-2470 v2 @ 2.40GHz
2. Would the CPU clock speed on a single core also made the 64bit Oracle slower?
Thanks a lot.

32 or 64 bit normally won't cause much performance difference as long as you can't use > 4GB RAM
Please note that XE can use only 1 core and 1GB memory.
According to benchmarks, Single Thread Rating of the 2 CPU really differ by around 25%. Quite consistent with your observation.
Of course, IO (i.e., disk) speed is also an important factor.

Oracle 9i, 10g, 11g on same machine...11g not working....

Hello All,
I have a dilemma.
I have a server that originally had 9i client installed.
We installed 10g and ODP .Net to gain use of some new funcionality used in .Net and batch processing.
Halfway through testing we realized that 10g's version of ODP.Net has a memory leak issue.
11g was found to correct this issue so we installed it on the server as well and it solved the problem.
Life was good.
9i, 10g, 11g, and ODP.net were all working well.
However, this was a test server. We now needed to go through the same installs for the production server.
On the night of the software install someone made a mistake and installed 10g on the test server again for the second time, after 11g was already installed.
So at this point the test server has:
9i
10g
11g
10g
And now many of the applications on the server are not working correctly and no amount of config changes seemed to fix it.
So we decided to uninstall 11g and then 10g and start over.
At this point we have 9i and 10g installed and the applications are working correctly.
We have tried to reinstall 11g and configure multiple times and 11g will simply not work.
I am stumped at this point. The application that actually does use 11g and ODP.Net simply stops executing at the point it attempts to open a connection with NO ERRORS.
An Exception does occur but there are no contents or error messages in the exception. I have never had this happen before. How do you fix an error you dont have?
So at this point I am just reaching out to see if anyone might have a suggestion. The next step might be to perform a system restore to the point where life was good (before 10g was installed a 2nd time after 11g).
Anyone?

Thanks gdarling.
I was hoping to just start the thread and go from there as sometimes information overload makes people pass on reading the whole post. I am glad you still read it:)
To start off with here are the entries (unedited in my PATH variable):
E:\oracle11\product\11.2.0\client_1\bin;E:\oracle102\product\10.2.0\client_1\bin;E:\oracle\product\10.2.0\client_1;E:\Orant9i\bin;
I recently moved the 9i path back to the front in order to get the other applications on the server working again as some were erroring out with this when 11.2 was first:
*"OCIEnvCreate failed with return code -1 but error message text was not available"*
I searched for a long time as to the cause of this error but did not turn up much. Most of the posts just mention that the client was installed incorrectly.
Policy files:
I compared the assembly of the "working" server to the "bad" server and they appear identical as far as I can see.
Directories
-9i has one directory
-As you can probably see from the path, it still looks like there are 2 installations of 10g on the server. As well as remnants of three directories that resemble 10g install directories.
-11g has one directory
Couple observed behaviors:
1.
running sqlplus from the 9i and 10g directories works.
running sqlplus from the 11g directory results in the following error:
E:\oracle11\product\11.2.0\client_1\bin>sqlplus.exe
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
2.
Running tnsping works from the 9i and 10g directories
Running tnsping from 11g results in this:
TNS Ping Utility for 32-bit Windows: Version 11.2.0.1.0 - Production on 13-MAY-2
010 09:32:32
Copyright (c) 1997, 2010, Oracle. All rights reserved.
Message 3511 not found; No message file for product=NETWORK, facility=TNSTNS-035
05: Message 3505 not found; No message file for product=NETWORK, facility=TNS
*(NOTE: THIS ERROR ALSO OCCURS ON THE "GOOD" SERVER)*
Registry:
There is a difference in the registry.
The "good" server has this entry in the ORACLE area:
KEY_OraClient10g_home1
KEY_OraClient11g_home1
where as the "bad" just has
KEY_OraClient10g_home1
Both servers have ODP.Net folder containing:
2.112.1.0
There are also other entires in this registry area but they are the same.
It wasn't our original intention to have all three clients on the same machine. Halfway through our system testing of a new process we realized the 10g has a memory leak which was corrected in 11g.
So we just installed 11g. These are supposed to be able to coexist right?
It sounds like we could have just installed 11g...
I am going to look into your suggestions.
As far as sysinternals I am a novice. And I am assuming it would need to be loaded on the server...is that correct? Or should I be using it on my local machine with the application in question running?
Getting more software (sysinternals) installed on the server might be a hurdle...
Thanks again

How import 10g,11g dump file in oracle 9 and oracle 8

Dear all
I import dump file exported from oracle 9 to oracle 10g and 11g now i want exported dump file from oracle 10g/11g to import in oracle 9 (lower version).
How said job will be done.
Thanks

I've already tried your method, but it fails when you import the dmp exported from lower version.
To import Oracle 11g user to Oracle 10g, the following method works fine:
It is assumed that both 11g and 10g servers are on same LAN.
Make sure that 11g sqlplus connects to your 10g server.
Step 1. Export the 11g user from 11g machine.
Step 2.Import the dmp file created in step 1 into 10g server from 11g machine itself.
The 11g exp/import utility should be used for both export and import operations.
Only source and destination servers will be different.

Oracle 10G/11G with JBuilder

Hi Gurus,
I am new bie in the Java development world. I am looking for purchasing a laptop on which I can install Oracle (either 10G or 11G does not matter) and JBuilder as the project on which I am going to work on uses JBuilder tool.
I have two questions
1) Is Windows 8 comptaible with Oracle 10G or 11G ?
2) Also can I install JBuilder on a Windows 8 Laptop ?
Regards
Fm

Thanks Timo for getting back to me so promptly. I do understand that this forum is not for JBuilder as Oracle uses JDeveloper to do the same stuff.
But can u specifically answer my question
1) Is Windows 8 compatible with Oracle 10G/ 11G ?
2) Assuming if its not yet compatible with Oracle 11G. Can we safely install JBuilder on Windows 7 and use it with Oracle 10G.
Please advise. I value advise from experts like you.
Cheers !

Oracle 10g / 11g is ROLAP/MOLAP/HOLAP?

Hi Greets,
Can any one please tell me whethe the available version of Oracle 10G /11g OLAP
is ROLAP or MOLAP or HOLAP.
Thanks
Anandraj

The OLAP Option is highly integrated with the Oracle database by this stage (11.1). Metadata is stored in the data dictionary and the primary access mechanism is SQL. So traditional terms like ROLAP, MOLAP, and HOLAP are getting hard to apply. But at a broad level you could say the following.
ROLAP was supported in 10g based on CwM metadata and the Java OLAP API as query tool. (Both Discoverer for OLAP and the Excel Add-In use the Java OLAP API.) CwM was deprecated in 10.2 and ROLAP in general has received no new development for years. So while it technically still works in 11g, I would not recommend it.
MOLAP (i.e. the Analytic Workspace) is supported in both 10g and 11g. In 10g the metadata is managed by AWXML, and in 11g it is managed using by the OLAP API. In both cases you can access the data via SQL, the OLAP API, or OLAP DML. In 11g you can also integrate with the Materialized View system.
The MOLAP implementation is faster and more scalable than the ROLAP version, and all development and future plans centre around MOLAP.
