Oracle 10g Vs Oracle 11g Scripts

Hi
We have a production environment that has Oracle 11g and development environment with Oracle 10g.
Scripts for:
1. Creating tables with constraints
2. Insert/Update/Delete records
3. Create Triggers
4. Create Stored Procedure
will be developed in Oracle 10g. These scripts will be executed in Oracle 11d production environment.
Will this create any issue?
Are they any syntax/procedure change in Oracle 11g?
Help required...
Thanks

What version of Oracle will you be running in test?
Why would you be running different Oracle versions in different environments? That doesn't generally make much sense other than when you are in the middle of an upgrade in which case you would have upgraded the development environment first, not last.
For the most part, ignoring bugs and the occasional depricated package, code that compiles in 10g should compile in 11g. But there is no guarantee that the behavior (particularly performance) will be similar. You'd need to verify that each script works correctly in the new environment.
Look at it this way-- would you blindly upgrade your production database from 10g to 11g without retesting the application? If you wouldn't do that, you shouldn't assume that the same script will behave exactly the same way in 11g as 10g. Most things will almost certainly work the same-- you just won't necessarily know where the deviations are until you try it.

Oracle 10g vs Oracle 11g query performance

Hi everyone,
We are moving from Oracle 10g to Oracle 11g database.
I have a query which in Oracle 1g takes 85 seconds to run, but when I run the same query in Oracle 11g database, it takes 635 seconds.
I have confirmed that all indexes on tables involved are enabled.
Does anyone have any pointers, what should I look into. I have compared explain plans and clearly they are different. Oracle 11g is taking a different approach than Oracle 1g.
Thanks

Pl post details of OS versions, exact database versions (to 4 digits) and init.ora parameters of the 10g and 11g databases. Have statistics been gathered after the upgrade ?

We are planning to Upgrade our databases to Oracle 10g RAC - Oracle 11g RAC which is Linux Environment. Kindly suggest me the best option for migration. Our production database size is 80GB.
- Frest installation of oracle 11g using export/iimport dumps
- Migration
- Upgrade process
Any information regarding this will be appreciated.

Pl identify exact versions of "10g" and "11g", along with the exact OS versions.

Upgrade steps needed - Oracle 10g to Oracle 11g in RHEL 4

Hello,
Am in the process of upgrading oracle 10g with 10.1.4.3 IDM,10.1.0.5 DB and 10.1.4.2 portal version to Oracle 11g. Now I see that there are some compatibilities in the OS. I have RHEL 4 and when I check the compatibility guide I see that it is possible to install/upgrade the oracle to 11g. But am worried on the kernel and packages which is needed for Oracle 11g. If there is any step by step assistance on this please guide me. Also I have an another query can I upgrade the OS RHEL 4 to RHEL 5 and then Oracle 10g to Oracle 11g. Will I be seeing any issue after the OS upgrade with product upgrade. Kindly advise me.
R/Ganesh

This is all about libraries, some libraries between RHEL 4 and 5 had change and this may lead to malfunction of some products, cause they have been copiled using old libraries that doesn't exist now, even I think in the upgradres there are compatibility modes where let you keep old libraries, anyway seems a difficult thing to do. If you plan to move RHEL 4 to 5, I think this is your first step and then install again the Portal in the old version, and then make the upgrade, If you make this step by step, as firts install RHEL 5, install db, install portal, upgrade DB and finaly upgrade portal, would be easier.

Hi
i have a web application have 10G database engine, now i will upload it on a host server witch supports oracle 11G database.
can i export Dump file from my Oracle10g database and import it into oracle 11G database successful.
what can i do?
please suggest me
thank you

Hi,
Difference btween oracle 10G database & oracle 11G database Here is a complete list:

can i export Dump file from my Oracle10g database and import it into oracle 11G database successful.Yes. Oracle supports backward compatibility . . .
You mght not, however do it the other way . . .
Hope this helps . . .

SQL performance slow -- oracle 10g to oracle 11g

Hi,
We are have two development server, here we can call server10 and server11.
Server’s having same hardware and OS, but different oracle version, server 10 and server 11 having oracle 10g and oracle 11g respectively.
Problem, when you run sql query in oracle 11g it’s very slow compare to oracle 10g server.
Here I have checked
1)     sga size – comparatively 11g size is big
2)     no full table scan
OS – SUN
DB: 11.1.0.7.0, 10.2.0.4.0

Will Oracle 10g and Oracle XE happily co-exist on same machine?

I can't seem to find anything specifically saying that Oracle 10g and Oracle XE can be installed on the same Windows machine. The only reason I'd want to do this is that I originally had the free version on my Windows machine. The uninstaller nevers seems to run a complete job and always leaves bits over. So I'd like to install Oracle 10g alongside Oracle XE.
Wondered if anybody had done this already?

to uninstall Oracle, do the following:
1. Uninstall all Oracle components using the Oracle Universal Installer (OUI).
2. Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE key. This contains registry entires for all Oracle products.
Delete any references to Oracle services left behind in the following part of the registry:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*
It should be pretty obvious which ones relate to Oracle.
4. Reboot your machine.
5. Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
6. Delete the "C:\Program Files\Oracle" directory.
7. Empty the contents of your "c:\temp" directory.
8. Empty your recycle bin.
At this point your machine will be as clean of Oracle components as it can be.
Remember, manually editing your registry can be very destructive and force an OS reinstall so only do it as a last resort.

Oracle 10g OLAP to 11g OLAP upgrade ?

We currently are planning on a upgrade from 10g OLAP => 11g OLAP. We currently have 12 AWM's in 10g OLAP which we need to move over with associated DML programs and additional SQL reporting views.
Questions:
1. Is there any documentation available on necessary steps for 10g OLAP => 11g OLAP upgrade?
2. What would happen to existing AWM's prepared in 10g, would they be migrated to 11g transparently or have to be re-created?
3. Is there any specific documentation related to changes in way cube builds are done programatically?
4. Any changes in the way limit maps work in 11g?
Please advise.
Thanks,
Sudip

Migrating a 10g cube to 11g depends on whether you are talking about 11gR1 or 11gR2. 10g cubes continue to operate in the "10g way" even after a database upgrade. They will not become "11g cubes" until they are rebuilt after the database upgrade. In 11gR2, there is a supported way to migrate 10g cubes to 11g cubes, both with AWM and with PL/SQL. Sorry to say... this functionality doesn't exist in 11gR1: you'll have to rebuild your cubes from the ground up.
The SQL relational views built using the AWM plugin in 10g are no longer applicable in 11g. That's because OLAP cubes in 11g are registered in the oracle data dictionary (just like other Oracle objects), and the SQL relational views are managed in the database and a recognized part of the product. The SQL relational views are quite different in 11g, so you will likely have to rewrite queries against them.
LIMIT map syntax is the same, but performance is much better.

Oracle 10g RAC to 11g RAC Upgrade on Solaris

Hi,
We are planning to do a migration of a 4 Node Oracle 10g RAC on Solaris 9 to 11g with Solaris 10. We'd like know what would be the best path to take. We cannot afford any downtime!
Options: Are these feasible? Which option is best? Any documents links?
a) Do a rolling upgrade of Oracle from 10g to 11g. Then take down individual nodes and upgrade the Solaris OS from 9 to 10 and bring them up back into the cluster. Is there any known issues taking this path? Is a rolling upgrade like this possible?
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?
c) Use Dataguard with 2 different RAC environments (2 nodes each). How would this work? Is it the only possible way? Any steps please?
Thanks

a) Do a rolling upgrade of Oracle from 10g to 11g. Then take down individual nodes and upgrade the Solaris OS from 9 to 10 and bring them up back into the cluster. Is there any known issues taking this path? Is a rolling upgrade like this possible?Hi,
first of all i would not change several components (OS, database version) at a time. My recommendation is to make small steps and start with the operating system first. Seconds recommendation is to test and test everything in your dev or test environment prior doing the upgrades in the productive environment. Trust me: You will face problems :-) So you better try it beforehand!
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?As far i know you can run different operating system versions on different nodes if they are supported (Solaris 9 and 10 are).

[Beginner Oracle 10g on Solaris 10]Script Root.sh asking road

Hello,
Need help please, Iam near the end of my installation Oracle 10g on Solaris 10, Oracle installer ask me to execute Root.sh, he ask me a path, suggesting me this road /usr/local/bin
The message is Enter the full pathname of the local bin directory : usr/local/bin/ ?
my path is
$PATH=/usr/bin:/usr/dt/bin:/usr/openwin/bin/:usr/ucb
$ORACLE_HOME=/export/home/oracle/oraInventory.
This message follow after I executed orainstRoot.sh successfully.
Thx for any help.
Edited by: user583169 on Feb 24, 2009 1:41 PM

This script asks for path where oraenv, coraenv and dbhome scripts should be copied/created.
Default (suggested) path (full path to directory) is /usr/local/bin directory but you can specify your own directory.
So you have at least two options:
1. Use default location and put /usr/local/bin to your $PATH environment variable
2. You can specify your own path which exists (is set) in $PATH variable (for example /usr/bin)

Xpath difference between Oracle 10g and Oracle 11g

All,
I'm working on moving our existing stored functions from Oracle 10g (10.2.0.4.0) to Oracle 11g (11.2.0.1.0) and so far, everything has worked just fine on Oracle 11g...execpt for one xpath statement.
The statement below works fine in Oracle 10g (10.2.0.4.0):
extractValue(inv_dtl_img, '/service//ground/sortKeyCode') AS "srt_key_cd",
Please note: I need to use the double slash "//" in order to ignore the two different elements in the schema.
However, in Oracle 11g (11.2.0.1.0), when this statement is executed in the stored function, I get this:
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected - got -
The extractValue command is pulling data out of an XMLType column, and the corresponding XML schema looks like:
<service>
<trans>
<ground>
<sortKeyCode>
</sortKeyCode>
</ground>
</trans>
<nontrans>
<ground minOccurs=0>
<sortKeyCode>
</sortKeyCode>
</ground>
</nontrans>
</service>
Please note: In the XML message, the "trans" and "nontrans" elements are exclusive, so both will never be populated at the same time. A typical XML message would look like this:
<service><trans><ground><sortKeyCode>3</sortKeyCode></ground></trans></service>
or this:
<service><nontrans><ground><sortKeyCode>5</sortKeyCode></ground></nontrans></service>
In the schema, the sortKeyCode has been defined in both places as "string maxlen=3", so the datatype of that element is exactly the same in both the "trans" and "nontrans" sections of the schema. The only difference in the schema (outside of the trans and nontrans tags) is the fact that the second "ground" tag is defined with a "minOccurs=0". Could Oracle 11g be treating the schema differently than Oracle 10g, resulting in the error?
Any thoughts would be appreciated.

The only way to get an quick answer to that one is to file a service request with Oracle support. It could be a bug or a correct change regarding W3C behavior. Despite this, you moving to 11.2, the extract/extractvalue etc propriety Oracle solutions are deprecated from 11.2 and onwards. The more sensible way to move forward, although, I know more work intensive, is to apply the XQuery alternatives like xmlexist, xquery or xmltable functions.
Moving to EXTRACT is a bad idea, because this alway will be treated as an XML fragment. If you unlucky then Oracle will deal with this in memory via DOM (the standard solution regarding XML parsing if every smart thing within Oracle can not be applied) and this will result in a performance downgrade due to high CPU and Memory consumption/overhead...
Your pick...

Difference between Oracle 10g and Oracle 11g when using Distinct in SQL

Hi All,
When I use Distinct in Oracle 10g, the result would be sorted in ascending order automatically, while there is no sorting in the result set in Oracle 11g.
I was using plsql developer to run my sql.
May I know if anyone have the same experience before?
Is there any kind of setting in 11g that I can make the result in order? Thanks!
Edited by: user5810051 on 2011/4/6 下午 8:47

As acadet says, if you want your result ordered you must specify an ORDER BY clause in your query. Just because previous versions of oracle included some ordering as part of the processing of a query, that was not a guaranteed ordering, but just a side-effect. Now that Oracle have improved the internal workings, they've removed the side-effect, and that's why you're not getting the ordering you want, because you were relying on that side-effect rather than explicitly stating the order you wanted.
