Help required in upgrading from 9i to 10g server

Hi All,
Our company is upgrading from oracle 9i to 10g in Unix environment.
As a Oracle developer my work is to ensure that oracle 9i programmes should suceessfully work in 10g also.
Please provide me some good links and articles about any pitfalls or code that has to be changed.

You may want to read this manual:
Oracle® Database New Features Guide
10g Release 2 (10.2)
Part Number B14214-02
so you get acquainted with the new features and you can assess, according to the new features, which are the most important in your case.

Frequent Rebuild Requires After Upgrade from 9i to 10g

Hi Friends,
Recently we have upgraded our production database from 9i to 10g and after that the performance of certain queries degraded drastically. when we did a workaround of rebuilding the table and associated indexes for these queries, it performs as fast as 9i.
Can anybody clarify why the same query which was working very fine without rebuild in 9i requires a rebuild in 10g?
Please note that the tables involved in this query are very huge and a frequent rebuild is not a permanent solution for us :-)
Regards,
Savad

Pl identify which "10g" - there are two flavors. Pl also see these MOS Docs

Please help required to upgrade from Snow Leopard to Mountain Lion.

Hello Community!
I have a iMac model 11,3. With 27" screen, Intel Core i7 2.93 Ghz, 12 GB ram, 1 TB hd.
My only internal disk is "Macintosh HD".
It's now running Snow Leopard fully updated to the latest.
I bought and downloaded Mountain Lion from the App Store.
But it refuses to upgrade saying "This disk cannot be used to start up your computer".
This seems so stupid because its starts the computer with Snow Leopard each time.
So please, anyone can tell me what is happening and how to solve this ?
Thanks in advance.

Perhaps these two links would be of help:

Help required in upgrading from 8.1.5 to 8.1.7

We are having our application running on forms 4.5 and oracle 8.1.5 on winNT and Win2k. Now for the time being we want to upgrade to oracle 8.1.7, for that I need all steps to be performed, can any one help me? Pls!!!

Hi,
normally there is a file "Readme.html" in the root of the patch CD/directory that states the upgrade path.
I don't have by the hand a 8.1.7 CD, but the standard path is:
- Disconnect all the clients
- shutdown DB using shutdown immediate
- stop all Oracle services (Listener, Agent, Management Server, etc.)
- Make a full backup
- Install new version of the software
- FIx Init.ora parameters
- startup DB with STARTUP MIGRATE
- execute the catpatch script
- shutdown immediate
- startup
But Readme instructions that follow the product version may state something little different so IT IS MANDATORY to follow the instructions.
Hope this helps

Sorting issue after upgrade from 9i to 10g

Dear all,
It is found that the sorting behavior is different after upgrade from 9i to 10g.
In 9i, even if the SQL statement does not specify the ORDER BY clause, the sorting order is consistent for a particular SQL statement and most likely the sequence follows the searched key fields' order.
After upgrade to 10g, the query output could vary as long as the SQL statement does not specify the ORDER BY clause.
Is it due to the Reverse Docid Sorting issue? How can I troubleshoot this issue?
Thanks for your help,
M.T.

Thanks for your help,
M.T. This is expected behavior in 10g. Oracle will not order the dataset for you unless and until you explicitly specify it.
So without using order by clause in 10g, oracle doesn't guarantee that rows will be ordered.
To go back to old behavior like 9i, you can set a workaround by
alter session set "_newsort_enabled"=false;

Upgrading from 9i to 10g on OS X?

Has anybody successfully upgraded from 9i to 10g on OS X?
I am stuck with Mac OS X 10.2.6 Jaguar for the next several weeks until I can upgrade to 10.3.4 Panther. According to the Oracle 10g on OS/X Oracle Installation Errata Information and Tools ( see http://www.crispdata.com/oracle_osx/ ), 10.3.4 is required for 10g installation.
In the meantime, I would prefer to experiment with 9i to learn more about Oracle database technology, and then upgrade to 10g after upgrading the OS to 10.3.4.
Has anybody already done this? Is this feasible?

Would it be sufficient to just set the passwords to expired? In this case generated the needed statements on your source DB and apply them on your destination DB, i.e.
select 'alter user ' || username || ' password expire;' from dba_users where account_status like 'EXPIRED%';
You might also consider other status values. Possible values are
OPEN
EXPIRED
EXPIRED(GRACE)
LOCKED(TIMED)
LOCKED
EXPIRED & LOCKED(TIMED)
EXPIRED(GRACE) & LOCKED(TIMED)
EXPIRED & LOCKED
EXPIRED(GRACE) & LOCKED
e.g.
select 'alter user ' || username || ' account lock;' from dba_users where account_status like '%LOCK%';

Report upgraded from 6i to 10g not displaying data.

Hi,
I upgraded one report from 6i to 10g,
When I'm running the report for the same set of data.
After changing the layout for few fields in the subframe.
first time it has shown the data in the report output but now same report with same data is not displying the output.
I'm sure this is due to some layout problem.(may be due to upgradation from 6i to 10g)
Please guide me to resolve this problem.

Hello,
How do you execute your Reports ?
Do you execute it from the Builder ?
If you execute it from the Builder, do you use Run Web Layout or Run Paper Layout ?
(If you have upgraded a Reports From 6i, there is no web layout , so you have to use the Run paper Layout
The web layout is something new that appeared in Reports 9.0.2)

Issue in oracle upgrade from 9i to 10g.

Hi,
I have an MS access application running on oracle database.Recently database is upgraded from 9i to 10g.
After upgrade application is facing the conversion problem.it is throwing an error on varchar and time stamp field showing invalid timestamp message.NLS setting of both the version is same.Please suggest.

Thank you,
Here are the answers of your queries.
Yes,This is affecting only MS access application because no other application is accessing this database.
No,No other component of the application is changed or upgraded it is only database which is upgraded.
The error is ORA-06502:PL/SQL:numeric or value error:Character to number conversion error.(In the application the value of this field is defind as Double and in database table it is VarChar and the system was working fine untill database upgrade after upgrade it is giving above error.)
For another field it is giving the error "No valid timestamp" although the same was working fine before upgrade.
No I have not traced the actual sessions but from the backup of 9i I have checked NLS setting and compared it with 10g and found that both are the same.
Hope I have not confused you.

Tag not being created after upgrade from 9i to 10g

We're upgrading from 9i to 10g - about time - and we've hit some "unexpected behaviour".
If I run
    SELECT xmlelement("TestMsg",
                    XMLFOREST(m.tx_id   "MsgNum",
                              m.tx_type "MsgTyp"
                              ) MESSAGE -- this is the alias for the XMLFOREST item
                    ) ut_xml
    FROM (select 1 tx_id, 'test' tx_type from dual) mon my 9.2.0.4 database I get
<TestMsg>
<MESSAGE>
    <MsgNum>1</MsgNum>
    <MsgTyp>test</MsgTyp>
</MESSAGE>
</TestMsg>- an extra tag is created based on the alias of the XMLFOREST item.
on my 10.2.0.4 database I get
<TestMsg>
<MsgNum>1</MsgNum>
<MsgTyp>test</MsgTyp>
</TestMsg>no MESSAGE tag.
Some of the XML parsing we have is taking account of this MESSAGE tag and hence is now breaking.
I guess my question is whether we've messed up the install of XMLDB or whether the 9i behaviour was incorrect and we should amend the parsing to the 10g behaviour.

Behavior change...?
SELECT xmlelement("TestMsg",
                    xmlelement("MESSAGE",
                    XMLFOREST(m.tx_id   "MsgNum",
                              m.tx_type "MsgTyp"
                    )) ut_xml
FROM (select 1 tx_id, 'test' tx_type from dual) m
will give output in 10.2.0.4.0 EE
UT_XML
<TestMsg>
   <MESSAGE>
      <MsgNum>1</MsgNum>
      <MsgTyp>test</MsgTyp>
   </MESSAGE>

Upgrade from 8i to 10g

Can a direct upgrade from 8i to 10g is possible?
OR
Do we need to upgraded from 8i to 9i , before we upgrade to 10g?
If we can migrate from 8i to 10g , directly please suggest me the metalink note number.
Thanks
Naveen

Dear Naveenanand,
I Agree with Jaffy!,
You can direct upgrade only if the current version is 8.1.7 or up. If this is not your case, you will need Upgrade to an intermediate Oracle Database release before you can upgrade to the new Oracle Database 10g release.
Here is a example:
8.0.n -> 8.1.7.4 -> 10.2
8.1.n -> 8.1.7.4 -> 10.2
All information you will need, you can found in this link:

Does anyone upgrade from 9iAS to 10g?

Dear all,
Does anyone upgrade from 9iAS to 10g only? The EBS version (11.5.8) and the oracle database version (9.2.0.4) are still same.
Best Regards,
Amy

You can upgrade 9i database to 10g in Ebusiness suite using metalink note
Note:362203.1 Oracle E-Business Suite Release 11i with Oracle Database 10g Release 2 (10.2.0)
Note:369693.1 Using Oracle Applications with a Split Configuration Database Tier on Oracle 10g Release 2
But for the application server components you can follow
Note:125767.1 Upgrading Developer 6i with Oracle Applications 11i
But Application server itself should be upgraded from 9iAS to 10gAS if you are planning to move your oracle applications Ebusiness suite to release 12.
Check the following metalink note
Note:403339.1 Upgrade R11i to R12
