Compatible parameter set too specifically will it affect my database?

Hello,
I performed an upgrade from 9 to 10.2, when setting the compatible parameter I set that to 10.2.0.5 instead of 10.2.0.
I know that according to note 830576 and the guide, that parameter should be 10.2.0 but since I can't change it, I want to know if there would be any problems with the database or the SAP system
Thanks in advance

Hello Maria,
at first you should understand what happens when you set this parameter. Please check the official documentation for a detailed explanation: http://docs.oracle.com/cd/E11882_01/server.112/e25494/create005.htm#ADMIN11112
I want to know if there would be any problems with the database or the SAP system
Running your Oracle database with a 4 digit compatible parameter is not a "problem", but maybe you are not able to perform a rollback of the 10.2.0.5 patchset without a restore anymore. That's the reason why SAP (and other vendors) recommend to set only 2-3 digits of the oracle version.
Only Oracle knows, If the current patchset 10.2.0.5 (already) changed some stuff that is incompatible with an older 10g R2 patchset.
- A new feature stores any data on disk (including data dictionary changes) that cannot be processed with your previous release.
- An existing feature behaves differently in the new environment as compared to the old environment. This type of incompatibility is classified as a language incompatibility.
You can try to lower it and restart your DB - if your database is already incompatible you will get an ORA error.

Oracle 9.2.0.7 vs Oracle 10.2.3 with COMPATIBLE parameter set to 9.2.0.7

Hi,
First off, I am NOT an oracle DBA (or even a DBA!), so please excuse my ignorance or errors contained within this post.
My client is currently planning to upgrade their 9.2.0.7 database server to 10.2.3. Reading through the oracle upgrade documentation, I came accross the compatible parameter, and further more you can set it to 9.2.0.7. I realise that by setting this, many new features introduced in Oracle 10g will not be available - however getting of the unsupported 9.2.0.7 platform is priority.
Can someone please advise what are the differences between a real 9.2.0.7 database server versus a 10.2.3 (with 9.2.0.7 compatible) server. By setting this will it guarantee sql scripts and external applications continue to work after the upgrade? I.e the list of compatibility issues detailed in the oracle database upgrade guide, will these issues be made irrelevant by this setting?
Your expert knowledge is appreciated.
Regards,
Shan

When upgrading from 9i to 10g the compatible parameter should be set to 9.2.0. All of the new feature will only be available when the parameter is set to 10.0.0 or higher and the instance restarted.
Once an instance has been restarted with a compaticble value of 10.0.0 it can never be set back to 9.x.
Why do you think the upgrade is required if you still want to use the features of 9.2.0.7?

My sync with other browsers data is not working - data not being transferred. I accidentally typed in wrong e-mail address when setting up. Will this affect things - if so how can I change it?

No more details

So nothing under Service Book mentions you're friend's calendar or email address?
If not I'd recommend using the Backup and Restore feature in Desktop Manager to make a backup of all your data. Next I'd wipe the device. To do that go into Options | Security Options | General Settings. Hit the menu button and choose Wipe Handheld. Doing so will erase ALL the data from your device and restore it to factory specs.
Afterwards you can re-setup your email accounts and the google apps to get your information on there. You could then go back into Backup and Restore | Advanced and restore certain databases (mainly the address book and the messages). If you were to do a full restore then it would probably bring back the corrupted email address problem that you're having right now

11gRel2 DBCA - using compatible parameter 10.2.0.3.0 results in ORA-00201

Hi guys,
Following is the scenario:
1. Oracle DB Binaries: 11.2.0.2.2
2. Using dbca to create General Purpose Database and then modify initialization parameter "COMPATIBLE from 11.2.0.0.0 to 10.2.0.3.0" in the "All Initialization Parameters" window.
So, when I finally start installing database, I get following error during the install:
ORA-00201: control file version 11.2.0.0.0 incompatible with ORACLE version 10.2.0.3.0
ORA-00202: control file: '/u01/app/oracle/cfgtoollogs/dbca/infpp1/tempControl.clt'
IGNORE OR ABORT...
Now you might ask why i am doing this. Actually I want to install fresh 11grel2. database with lower compatible parameter. IMPORT DP custom schemas into this database making sure compatible is set to 10.2.0.3.0. Then run database with such settings for a week and finally change compatible parameter to 11.2.0.0.0
Any thoughts where i am going wrong? as the default template seems not accepting what i am interested to do.
regards,
Anjum

It is not clear why you need to have the compatible parameter set to 10.2.0.3 for the import - it will work perfectly fine with the default value (11.2.0.2) of the compatible parameter. As you have experienced, once you set this parameter, it cannot be changed to a lower value

COMPATIBLE parameter question

Our company makes an application which needs the COMPATIBLE parameter set to 10.2.0.1.0 . But our client says its db's COMPATIBLE parameter is set 10.2.0.3.0 . The only application that is going to run in this server will be our application. Do we have to ask the client to change the COMPATIBLE parameter to 10.2.0.1.0 or let it remain as 10.2.0.3.0?

On 10g the parameter COMPATIBLE cannot be downgraded, as once datafiles are open, they register this information on their headers.
In this particular case there is no conflict with the versions, as you are talking about the same functional version with different maintenances:
The first three digits refer to the major version and the functionality, meanwhile the last two digits refer to the DB and OS maintenance (bugs), but you are talking about the same version, 10.2.0.

Set COMPATIBLE parameter in 11.2 rdbms to 10.2.0.4?

OS: Windoze 2003/2008 x64 bit
Oracle 11.2 - 64bit
The situation is that some vendor supplied software is only "certified" for Oracle version 10.2.0.4 and the question is that if we install 11.2 and set the COMPATIBLE parameter to 10.2.0.4 will that software work without issues?
Any suggestions/criticism/ideas/experiences/links welcome.
Thx.
:)

My recommendation would be as follows given that all 10gR2 and older versions go into desupport mode August 1.
Tell the vendor they will either support those versions Oracle supports or they will immediately lose your business.
And if they do not give you a letter telling you they will support the move (and I don't mean with compatible set to something obsolete) then vote with your money and go to their competitor. One of the biggest mistakes companies make (and I see this everywhere) is not forcing vendors to sign a statement saying they will keep current with the versions of the Oracle database that Oracle fully supports. That is one of the reasons we have dinosaurs roaming these forums asking questions about 8.1.7 and earlier versions. It is inexcusable and we, the customers, should not let these cheap and lazy vendors get away with it.

her contacts are connected directly with the Google Server so as long as they are saved to her Gmail account she should be 100% fine.. the only contacts she may lose are the ones that she added directly onto the phone and did not sync to her Gmail account.. so you should just double check with her on that

Reset network setting in ios will reset that in mac too?

Every time I reset network setting in my iphone, my mac will also lost all saved wifi network. So, reset network setting in ios will reset that in mac too?

What do you mean? Like my wifi network at my home, school or public area. If I reset my iPhone's network setting, when I go back to home, my mac wouldn't connect to my home's network too. I have to retype the password. And I go to system preferences -> network -> advanced under wifi, I only see the wifi networks that my iphone has joined after resetting the network setting. That's why I think they are related, but I couldn't think of a reason why apple would do that. So i'm wondering if I set something wrong....

When, specifically, will adobe notify those customers who were affected by the recent security hack?

When, specifically, will adobe notify those customers who were affected by the recent security hack?

I just received a second email notification within the last half hour after receiving the first one about 24 hours ago. Both notifications told me my password has been reset and that I need to create a new one. I did that already last night.
The reset password is apparently still working, despite the second notice received a short time ago. It's not working well (takes forever for login to complete), but it is working.
I have no way of knowing whether Adobe has finished sending notifications to everyone who was affected - just reporting on my own experience so far.

HT1766 My daughter locked herself out of her phone cannot remember the advanced password setting, we share an Itunes account and both recently joined the cloud, if she resets her phone all her information will be gone, will it affect the data on my phone

My daughter locked herself out of her phone cannot remember the advanced password setting, we share an Itunes account and both recently joined the cloud, if she resets her phone all her information will be gone, will it affect the data on my phone as well

No, when resetting an iPhone it resets the actual data contained within the phone, nothing on your iCloud will be affected. It is a good idea to use seperate iClouda and iTunes accounts then you can each create your own backups regularly without your daughters backup overwriting yours or vice versa.

Mismatch between COMPATIBLE Parameter and Oracle Version

Hi,
If the ORACLE version is say 11g but the compatible parameter in init.ora is say 9.2.0 or 8.1.7 what will be the effect on the database?
Will the database behave as like 11g or of the lower version?
If we alter the init.ora to the new version for compatible paremeter will it affect DB rebooting?
This is an interview question and i could not answer.
Please let me know the answers.

IMovie keeps quitting. If I uninstall will it affect iPhoto?

i Had to have a new hard drive installed a few months ago. Since then my iMovie keeps quitting before I do anything. If I uninstall will it affect my iPhoto's?

Applications do not affect data or preferences.
But it sounds like the restore of your new hard drive brought along problems and errors from before, when the old drive "died" it probably just needed software repair and maintenance unless the drive's structure, the sectors that data reside on, had a few bad or weak sector blocks.
What are you doing for backups? maintenance? Mountain Lion Recovery for instance?
You need to start addressing the WHY and repair the disk drive directory, and the best medicine is not that bad or hard: backups, a clean install (save the Mountain Lion installer to flash drive), and then import using Setup Assistant.
And keep more than one backup set - so you have a 2nd set off line at any time.
Clone. Carbon Copy Cloner makes an exact bootable copy of partitions and under advanced setting, will do a checksum of each and every file to insure its integrity.
It is unlikely uninstall of the app is the issue. As long as everything is current, compatible, and you didn't install or keep older programs and 3rd party extensions and utilties interferring with Mac behavior and STABILTY.

INIT.ora-COMPATIBLE parameter

Hi,
My oracle version is 11.2.0.2 but in INIT.ora the parameter COMPATIBLE is set to 10.1.0.2.0.How does it impact DB?Does it mean that optimizer will use 10.1.0.2 features? Does it affect the performance of DB/queries in any manner?How will it impact if i change the vaue of this parameter t0 11.2.0.2 in INIT.ORA?Please throw some light on it

Thanks Hemant again.
Pasted from the link.
<How the COMPATIBLE Initialization Parameter Operates
The COMPATIBLE initialization parameter operates in the following way:
It controls the behavior of your database. For example, if you run an Oracle Database 11g Release 2 (11.2) database with the COMPATIBLE initialization parameter set to 10.1.0, then it generates database structures on disk that are compatible with Oracle Database 10g Release 1 (10.1). >
So eventhough the oracle version is 11.2.0.2.0 it works more or less like 10.1.0.2.Is my understanding correct?If so,then there is no point in upgrading oracle to 11.2 if this parameter has a lower value.Pls correct me.
Thanks.

BW Web Report Issue - Result set too large

Hi,
When I execute a BEx Query on Web I am getting “Result set too large ; data retrieval restricted by configuration (maximum = 500000 cells)”.
Following to my search in SDN I understood we can remove this restriction either across the BW system globally or for a specific query at WAD template.
In my 7x Web template I am trying to increase default max no of rows parameters, As per the below inputs from SAP Note: 1127156.
But I can’t find parameter “Size Restriction for Result Sets” for any of the web items (Analysis/Web Template properties/Data Provider properties)….in the WAD Web template
Please advise where/how can I locate the properites
Instructions provided in SAP Note…
The following steps describe how to change the "safety belt" for Query Views:
1. Use the context menu Properties / Data Provider in a BEx Web Application to maintain the "safety belt" for a Query View.
2. Choose the register "Size Restriction for Result Sets".
3. Choose an entry from the dropdown box to specify the maximum number of cells for the result set.
The following values are available:
o Maximum Number
o Default Number
o Custom-Defined Number
Behind "Maximum Number" and "Default Number" you can find the current numbers defined in the customizing table RSADMIN (see below).
4. Save the Query View and use it in another Web Template.
Thanks in advance

Hi Yasemin,
Thanks for all help...i was off couple of days.
To activate it I can suggest to create a dummy template, add your query in it, add a menu bar component add an action to save the query view. Then you run the template and change the size restriction for result set then you can save it by the menu.
Can you please elaborate on the solution provided,I created dummy template with analysis and Menu bar item...i couldn't able to configure menu bar item...
Thanks in advance

11gr2 database compatible parameter

I have a 11g r2 database and the compatible parameter was originally set to 11.2.0.0.0. I did an alter system set compatible='10.2.0.4' scope=spfiile;
Now when I try to start the database, it says control file version 11.2.0.0.0 incompatible with ORACLE version.
When I do a startup nomount and try to alter system set compatible='11.2.0.0.0' scope=spfile, I get ORA-32012: SPFILE format is inconsistent with value of COMPATIBLE parameter.
I also tried doing a create pfile from spfile and it gives me the same error. Is there anyway to fix this?
On another note, the reason why I tried this was because I tried installing Grid Control 10.2.0.3 using an existing database with this 11gr2 database. It doesn't let me proceed saying the database must be 10.2 or higher. It seems to not like my 11gr2 database version so that's why I tried changing the compatible parameter. Anyway to get around this?
Thanks for your help.

As for shutdown abort and create the spfile, Why are you trying to CREATE SPFILE???????
it can't find the spfile in the dbs directory because I'm using ASM.Please make up your mind.
Either spfile exists or it does not.
Are you having a problem with the ASM instance or "normal" (OLTP?) instance?
Too bad CUT & PASTE are broken for you!Why the hostility? It was a typo. I was creating a pfile, not spfile.
Let me clarify. I am using ASM for this "normal" 11gr2 instance, so my spfile is located in a diskgroup called +DATA. When you shutdown the database and try to create a pfile from spfile, it looks for the spfile in the default directory under $ORACLE_HOME/dbs. So since I'm using ASM, my spfile is not located in this directory and oracle can't find the file.
Anyways, after some googling I answered my own question. I had to use create pfile from spfile='+DATA/emrep/spfileemrep.ora';
Thanks anyways...
But any direction on installing Grid Control using a 11gr2 existing database for the repository is appreciated.

Compatible parameter set too specifically will it affect my database?
