Co-existing 9i and 10g clients

I have a mobile application running on about 300 9i Lite clients on WinCE 3.01 syncing over GPRS with 9i Mobile Server and a 9i database. I'm planning to upgrade the clients to a WM5/6 device and want to avoid a big bang cutover.
My initial thought is to upgrade Mobile Server to 10gR3, keeping 9i DB and the existing devices on 9i Lite. I would then introduce 10g Lite clients in phases so that the 9i Lite clients would be replaced over a couple of months.
I've had various reponses from Oracle about how well 9i and 10g clients will co-exist against a 10g Mobile Server - the summary of which is that it should work but it's not recommended or supported.
Does anyone have experience of whether this is a viable production solution during the transition period? Or are there any better ways to do a phased client cutover?
Thanks.

I am in a similar predicament at the moment as well. I know they can co-exist, but I have run into issues on a win32/webtogo platform. I will update this post if I find a bullet proof way of doing it.

Query using Materalized view in oracle 9i and 10g

Hello
There are snapshots (materialized view) used in my application. We have recently migrated from 9i to 10g release 2 database.
After migration i have observed explain plan of query which is using materialized view and i found in 9i oracle treating materalized view as table. In 10g oracle is considerting it as MVIEW only (MAT_VIEW ACCESS BY INDEX ROWID). However in 10g cost of query which is using materialized view is much higher than 9i. And execution time is also random.
Can anbody pls. expalin diff. of materalized view access in oracle 9i and 10g.
Thanks

can you post your query with explain plan for both 9i version and 10g version.
Thanks,
karthick.

Oracle 9i and 10g in one computer

Could I install oracle 10g in computer where 9i is instaled. I want that both oracle is instal and test oracle 9i and 10g. Could I run oracle database 9i and 10g together and I use both of the database?
Thanks for answer.
Rafal Dmitrowski

I would also suggest caution if you have a Windows server. While it is certainly possible to have both running, there are some issues with separate 9i and 10g homes on a Windows machine, things like the Oracle Home Selector doesn't work with 10g Oracle Homes. I wouldn't be overly concerned if you are dealing with development laptops, but I would make sure to do some testing before installing 10g on a production server with 9i already installed.

How SMON coalesces free space in oracle 9i and 10g

how SMON coalesces free space in oracle 9i and 10g?
Is it doing same as it was behaving in oracle 7 like looking through free extent table every five minutes (sys.fet$) to see if there are any adjacent free extents that can be coalesced into a single extent, and on every 25th cycle (i.e. every two hours and five minutes) it looks at the segment table (sys.seg$) to see if there are any temporary segments that need to be eliminated, as explained by jonathan lewis?
what are extent and segment tables available in oracle 9i and 10g like sys.fet$ and sys.seg$ in oracle7?

Issue with .profile for oracle 9i and 10g

Here I have six oracle 9i databases on one box. I am going to upgrade five of them to oracle 10g and want to keep one database RCAT in oracle 9i for one or two week.
So, when I do upgrade I have to setup oracle home for 10g and also profile for oracle user for 10g (correct me if I m wrong). But now I want one database RCAT on oracle 9i. How can I take care of this.
I mean how I will handle profile and all other thing for oracle 9i and 10g at the same time.
Thanks,
Vishal

Install 10g under the same OS user as 9i, of course on a different Oracle Home. Then you configure your .profile consequently. Just as an example, this is my .bash_profile with 10g and 11g with the same oracle OS user :
[oracle@linux5 ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
export EDITOR=vi

Data Replication between Oracle 9i and 10g

Hello,
I have a question regarding possible Replication Models between Oracle 9i and 10g. Does anybody know a possible way to syncronize the schema data between a 9i and 10g database in realtime?
If yes can you please post perhaps a link with a kind of how to?
Many thanks to all,
Bob...

You can read this metalink note 370850.1 - there are bit more ways of replication discussed.
Yes, platforms can be different, but recomendation is to use the same platform for both databases.

Do you have a listener 10g service ? Did you start it ? If not, please try the following :
C:\> set ORACLE_HOME=<Your 10g Home>
C:\> set PATH=%ORACLE_HOME%\bin;%PATH%
C:\> lsnrctl start

Oracle 9i and 10G professionals required

Hi All,
A company in Tanzania is looking for Oracle 9i and 10G professionals for immediate requirement. Those who are looking for change and has 4 to 5 years experience can send in your resumes to [email protected] Indians are preffered. Mention "ORJOB#040820081411" in the subject.
Kindly send in your resume as early as possible.
Thank you.

You can try setting the SGA to a low value and bring up both the databases. I don't think it should be too slow provided you are not running other windows programs.
If you are really interested in trying out new products you can also explore the option of installing VMware, creating virtual machines & installing Linux, and then playing with the different Oracle products. Doing this will at least keep your main windows operating system clean.

Oracle 9i and 10g differences in "group by"

I found the sorting order is different in "group by" function of Oracle 9i and 10g.
What is the reason?
>>>>>>>>>>>>>>>>>>>>>
SQL> create table t ( a number, b number);
Table created.
SQL> insert into t values (1,2);
1 row created.
SQL> insert into t values (100, 200);
1 row created.
SQL> insert into t values (10, 20);
1 row created.
>>>>>>>>>
9i
>>>>>>>>>
SQL> select sum (b) , a from t group by a;
SUM(B) A
2 1
20 10
200 100
>>>>>>>>>
10g
>>>>>>>>>
SQL> select sum (b) , a from t group by a;
SUM(B) A
2 1
200 100
20 10

in oracle "group by" doesn't sort. Not strictly true.
Pre 10g had an implicit order by which was caused by the way the database engine performed it's group by operation.
In 10g this has now been "refined" so that group by does what it says i.e. groups the data, without having the side effect of implicitly ordering the data.
In reality if you want data in a particular order you should always specify an ORDER BY clause and never rely on the fact that Oracle used to suffer from an implicit side effect.
