Going from 10gR2 to 11gR2 - any obvious performance 'pitfalls'?

Hi, there,
I'm moving some databases from 10gR2 to 11gR2. I was wondering whether there were any obvious pitfalls in performance that I should be aware of (like the optimizer ones in previous versions). I'm taking the SPFILE from 10gR2 and modifying it as little as possible to use as my 11gR2's SPFILE.
Also, I've heard murmurs of timezones being an issue in migrating to 11gR2? I'm either going to be using export/import or TTS to move my data. I wonder if the timezone issue is related to RMAN somehow.

Hi,
I performed an Upgrade from 10.2.0.4.4 to 11.2.0.1 two weeks ago.
I used a note from oracle support for manual upgrade to 11gR2
the database had database vault and also had auditing enabled.
these peculiarities are all covered in the note.
I would suggest that if you have auditing enabled, set the parameter audit_trail=none before you commence upgrade.
In addition make sure the you have tested the upgrade before implementing on your production environment, this would prepare you greatly.
after the upgrade, the timezone was upgraded to 11, database vault was turned on, EM upgraded, database vault application redeployed.
all the best

Upgraded Db from 10gR2 to 11gR2 want to know how can we make use of mem_target & mem_max_size parameter

Hi Guys,
Wish u all a very happy new year.
We have upgraded our Client UAT system on solaris 10 from 10gR2(10.2.0.4) to 11.2.0.3 with latest PSU patch 11.2.0.3.8 Solaris SPark 64 bit.
Post DB upgrade new parameters have been incorporated into the system namely
1. Memory_Target
2. Memory_Max_Size.
Now although we have our SGA and PGA set to some specific values in our system, what i want to know is how can we utilize the Two parameters i named above in the system and
how can it provide me better performance in relationship with SGA and PGA set in the system.
Probably on what concept does Memory_Target and Memory_max_size parameters work in 11gR2 system.
It would be really great if some one can provide the details with explanation.
Your help is appreciated.
Regards,
Milan Rathod.

Hi,
Automatic Memory Management(AMM) was introduced in ORACLE 11g to automate the size of SGA and PGA(takes full control of managing memory)
To configure AMM ,need to initialize MEMORY_TARGET and MEMORY_MAX_TARGET parameters.
MEMORY_TARGET:
The amount of shared memory available for Oracle to use when dynamically controlling the SGA and PGA.
This parameter is dynamic, so the total amount of memory available to Oracle can be increased or decreased, provided it does not exceed the MEMORY_MAX_TARGET limit. The default value is "0".
MEMORY_MAX_TARGET:
This defines the maximum size the MEMORY_TARGET can be increased to without an instance restart.
If the MEMORY_MAX_TARGET is not specified, it defaults to MEMORY_TARGET setting.
Let say If you are setting MEMORY_MAX_TARGET=2GB, then oracle will use these 2GB to manage the memory(Boh SGA and PGA)
If you set db_cache_size=1GB based on your requirement , then AMM always retains this 1GB memory for db_cache_size and it will use the remainng 1GB memory for other processes.

Migrating from 10gR2 to 11gR2 using impdp with network_link fails

Hi,
I'm trying to migrate a database from 10gR2 (Novell SLES 10) to a new server (Novell SLES 11) with 11gR2. I created a database on the new system with all required users and tablespaces. Then I used impdp in 11g with a database link to the source database:
impdp system/pw@db NETWORK_LINK=X_SourceServer FULL=Y
This command fails immediately with ORA-39113: unable to determine database version. Even using the parameter VERSION=10.2.0 doesn't change the result.
The Oracle Upgrade Guide tells me that upgrading is possible from 10* to 11* and recommeds impdp and network link. Is the failure perhaps a bug in the NETWORK_LINK procedure? Should I better try expdp on the source and impdp on the target with a dumpfile as intermediate (the database ist rather big, so dealing with files across the network will take a lot of storage capacity)?
Has anyone tried this method with success?
Thanks
Friedhelm

This is due to an bug. The workaround is in the DOC
IMPDP From 10g TO 11g Gives ORA-39113, ORA-4052 & ORA-6544 PL/SQL: internal error, arguments: [55916] (Doc ID 1062428.1)

Upgrade from 10gr2 to 11gr2 - error during impdp

Current server is 10gr2 on windows 2003 64 bit, running TDE. On the new server, I've copied the wallet to the new server, opened it using the alter system set encryption wallet open command. Verifed it's open. When I run impdp on the 11gr2 server, I get a ton of these errors:
ORA-39083: Object type INDEX failed to create with error:

Any ideas? I'm doing my practice runs for the real upgrade, which is this weekend, and I've had several successful upgrades, but this time I can't get past this error.

I do not have any experience with TDE, but see if MOS Doc 1260584.1 can help

11gR2 Infrastructure Upgrade Question(s) from 10gR2

Hello.
We are currently using both Linux (RHEL5) and Solaris (5.10) for all of our Oracle 10.2.0.5.0 RAC DBs. Weare NOT using ASM currently. So, we are going to upgrade our DBs to the latest version of 11gR2 - and this obviously will include our CRS. I know the ASM and CRS under 10g are now combined under the 11gR2 Grid Infracstructure. I have been revieiwing the Oracle Grid Infrastructre Installation Guides for both OSs. While these guides are centered on new installations, I do notice that each has a small appendix tied to upgrading activities (Appendix E in Solaris and Appendix F in Linux).
I also have a few papers I pulled from blogs related to these activities (e. g., a blog from David Marco and another from Martin Bach) where they are updating their clusterware from 10gR2 to 11gR2. So here are a a few questions I'd like to answer - one may be obvious from what I have already read.
1.) This may be the obvious or redundant question - almost the entire writeups in the earlier referenced appendices seem to center around an 11.x CRS to 11gR2. So are these appendices still the correct reference when going from 10gR2 to 11gR2? Just double checking myself/
2.) Sadly, we are not going to be utilizing ASM anytime soon (tied to $$ issues realted to fiber connections). We might later, however, go to ASM. Is there anything I should do in relation to this upgrade tied to ASM that might make it easier to say move over to ASM in the next year - or should I just ignore any references to ASM during this initial upgrade?
3.) Does anyone have any other additional document references/URLs that you might feel would be helpful in the overall 11gR2 upgrade process (both Infrastructure and/or DB)?
Thank you in advance for any help.
Matt

Upgradation from 10gr2 RAC to 11gr2

I am trying to upgrade my RAC database from 10gr2 to 11gr2. But after successfully completing rootupgrade.sh on all nodes, I am not able to see the registered components. i.e. "crsctl stat res -t" is not working. Even the active version is also showing the older one. My 10gr2 setup is in raw device. Has anybody faced the same issue before? Please share.
Thanks in advance.

Hi
please provide more details, what is your OS, what is the 10g version and what is the 11g version.
please post the output from crsctl status resource -t

10gR2 to 11gR2 usin rman

hi
I am dong (just started few days back)10g OCP (DBA).
i love to play with it lot.so i installed 11gr2 db version first.then i deleted the db orcl using dbca.NOW i am trying to install RAC..if i install RAC and create a db or restore a db from taking backup backup from a 10gR2 single instance(actually my institute run this db) db using rman.what would be the case?
will this db use the all the fetures of RAC 11gR2 or it will be just a single instance db by default OR do i really need to run rconfig after restoring it?
what it would be if the backed up db not using ASM?
My assumption is the 11gR2 will fail to restore the 10gR2 db.OR my be some parameter need to be change in spfile.
plz suggest
regards

You can not create a RAC cluster with the hardware you likely have.
Describe in detail hardware, operating system (w/ version), shared storage solution (and sharing the C drive in not an acceptable answer, and cache fusion interconnect solution.For RAC i have x86_64 two machines running with OEL5.4 /OEL5.2 ( and planned for using ASM).

For someone just learning Oracle I would recommend that you not even think about RAC for 2-3 years. You jumping into RAC is roughly equivalent to a student pilot deciding they want to fly the Space Shuttle. It isn't going to have an attractive outcome.do not get scares i am trying at my home.
First of all i would like to say:
............can you describe the thing theoretically?
in my case the incorporation is from win xp 32 (my institute runs by win xp 32bit )to oel 5.4 x86_64.that is the db of which i am taking backup is running under win xp and 10gR2 NOW i am restoring it under 11gR2 which is running under OEL5.4.
what will be the case?is it possible or not?
[as per i can remember the OCA stuff if i took the control /datafile/spfile file os level backup(ie.just copy-paste method ) and just try to restore it manually it may work--probably one of my friend did so(if my memory saves) ]
Another thing is that do i need to change something in spfile?if i can remember my OCA stuff well ,the Spfile probably stores some version information of the database release.so it should be changed or not?
regards
NB:- Actually i asked to my OCP instructor.he said it is not possible even from single instance backup and restoration if it is the case from 10gR2 to 11gR2 using rman.I just want a experts suggestions....

Going from CS4 to CS3

Greetings,
Once you've created a composition in a CS4 version of a program such as After Effects, are you able to open the comp in the CS3 version?
I know this problem arises with Adobe Audition when going from Audition 3 to any prior version, and I'm looking to go back to CS3 from CS4 (far too many bugs and I'm finding it far too unstable)
Thanks,
Sarah

You can copy keyframes manually if you have both versions installed on the same computer:

Need help with iphone 4s activation goes from hello to country to network and will not activate on network or itunes i am original owner with no obvious problems with phone any ideas

need any ideas on iphone trying to use again but now it goes from hello to country to network then tries to activate but on wifi and itunes both say sever unavailable any ideas?

That message usually means that your phone was once connected to a different phone carrier than the one you're currently on.
Then when you restore or updated the phone it locked back to the original phone carrier - this is caused when the phone was hacked to unlock it from the original phone carrier.
Very rarely is the activation server unavailable.

Hello jared1915
If you are stuck in that loop, the next step would be to restore your iPhone. Check out the article below to get your iPhone into recovery-mode and restore it in iTunes.

HT4623 The software update option is not on my phone. It just goes from "about" to "usage". I have an iPhone 3G. Every time I try to update it on iTunes, nothing changes. I have version 4.2.1, no matter what I do. Any suggestions?

I have an iPhone 3G, and cannot update my iOS. In the General tab, "Upadate Software" is not even there. It just goes from "About" to "Usage". When I try to update on iTunes, it always remains the same. iOS 4.2.1. Any suggestions? (My PC uses Windows XP). Also, my WiFi has completely quit working. Works fine on the other iPhones in the house, as well as the XBox 360, so I am sure it's my phone. I tried everything I could think of, including restoring the iphone to factory settings & then updating, but no luck. Thank you! for any help you can give! I plan to get an iPhone 5, but wasn't ready to do it quite yet. Hopefully my phone can be rescued until I'm ready.

That is the highest you will be able to go with 3g. You need 3gs or 4 to go any higher (multi processors and more memory needed). Version 4.2.1 marks the end of your updates for that device.

I just jazzed up my 2 Ghz iMac with 10.6.8, and 4 gigs of memory. I'm VERY happy with the results (fast!), but now I have a thin yellow line way over on the right side of the screen, which goes from top to bottom. This is really strange! Any input?

I'm VERY happy with the results (fast!). However, the really strange thing is this - there is now a thin yellow line, way over on the right side of the screen, which goes from top to bottom, and stays there no matter where I go or what I do. I've never seen anything like this! It was not there before I did the upgrades. Anyone out there ever heard of such a preposterous thing ~ or have any ideas on how to get rid of it?

Hello Mark,
It's going to mean a lot of reading but you should study the 'More like this' legend to your post's immediate right. >>>>>>>> plus some of the links within each.
The problem is well explored with much guidance on what to do and where to go.

10gR2 to 11gR2 from Windows to Linux with 6TB Database.

Hi,
I need to do migration from 10gR2 to 11.2.0.2.0 and from Windows to Linux for 6TB database Size. As both Endian format same, I did the migration using RMAN Convert database on UAT but for same 10gR2 version.(Both Source on Target Oracle Version was 10.2.01.0). Now I have to migrate from 10gR2 to 11.2.0.2.0. So it's 2 way process.
is it possible to club these 2 way migration process ???
Are following steps right or any modification is required ??
1) Install 11.2.0.2.0 on Linux OS
2) Open Source Database (Windows) in Read Only. Generate TRANSPORT.SQL, CONVERTSCRIPT.RMAN & Pfile.
3) Copy Source datafiles in temporary location on Target OS. Also copy above files.
4) Create dummy controlfile.
5) Startup nomount with Changed pfile
6) Mount database with Dummy Controlfile.
7) Run CONVERTSCRIPT.RMAN to convert actual datafiles from Windows Platform to Linux Platform.
8) Shutdown the instance and delele Dummy Controlfiles.
9) Edit TRANSPORT.SQL and do Appropriate Changes like redolog files, datafiles path...
Now my question is, can I add ?/rdbms/admin/catupgrd.sql in TRANSPORT.SQL script after Startup upgarade command so that Complete Upgradation to 11.2.0.2.0 would be done.
10) Then run TRANSPORT.SQL on Target System (11.2.0.2.0)
Tell me if more inputs are required from my side...
Regards,
Manish

Hi to All, My wife still has ios 6 on her ipad (she likes the look). I will do the 7.1 upgrade when it is released. Should there be any issues going from 6 directly to 7.1? Thanks!

Hi to All, My wife still has ios 6 on her ipad (she likes the look). I will do the 7.1 upgrade when it is released. Should there be any issues going from 6 directly to 7.1? Thanks!

There shouldn't be. I went from iOS5.whatever to iOS6.1 with no issues.
Just make sure to back everything up before you do it, just in case all doesn't go as planned.
I always do mine the old fashioned way, download the full OS via iTunes so if you've already got it linked to a computer and been using iTunes to do updates/syncing that's how I'd suggest you do it.
