DB upgrade during a Solaris upgrade using live upgrade feature

Hello,
Here is the scenario. We are currently upgrading our OS from Solaris 9 to Solaris 10. And there is also a major database upgrade involved too. To help mitigate downtime, the Solaris Live Upgrade feature is being used by the SA's. The DB to be upgraded is currently at 9i and the proposed upgrade end state is at 10.2.0.3.
Does anyone know if it is possible to do at least part of the database upgrade in the alternate boot environment created during the live upgrade process? So lets say that I am able to get the database partly upgraded to 10.2.0.1. Then, I want to run the patch set for 10.2.0.3 in the alternate boot environment and do the upgrade of the instance there too so that when the alternate boot environment is booted to the primary boot environment, I can, in effect, just start up the database.
That's sort of a high level simplified version of what I think may be possible.
Does anyone have any recommendations? We don't have any other high availability solutions currently in place so options such as using data guard do not apply.
Thanks in advance!

Hi magNorth,
I'm not a Solaris expert but I'd always recommend not to do both steps (OS upgrade and database upgrade) at the same time. I've seen to many live scenarios where either the one or the other has caused issues - and it's fairly tough for all three parties (You as the customer, Sun Support, Oracle Support) to find out the end what was/is causing the issues.
So my recommendation would be:
1) Do your Solaris upgrade from 9 to 10 and check for the most recent Solaris patches - once this has been finished and run for one or two weeks successfully in production then go to step 2
2) Do your database upgrade - I would suggest not going to 10.2.0.3 but directly to 10.2.0.4 because 10.2.0.4 has ~2000 bug fixes plus the security fixes from April2008 - but that's your decision. If 10.2.0.3 is a must then at least check Note:401435.1 for known issues and alert in 10.2.0.3 and for both cases the Upgrade Companion: Note:466181.1
Kind regards
Mike

How to upgrade from Solaris 10 u2 to Solaris 10 u3 using Live Upgrade?

Does anyone know how I can use "live upgrade" (or any other method) for upgrading my solaris 10 u2 to Solaris 10 u3?
I can't find instructions anywhere! ugh.
Thank you for your help!

Try the following documentation:
http://docs.sun.com/app/docs/doc/819-6396
For future reference, I found this by going to sun.com -> documentation -> Solaris Operating Systems -> Solaris 10 Operating System -> Solaris 10 11/06 Release and Installation Collection.

Looking for information on best practices using Live Upgrade to patch LDOMs

This is in Solaris 10. Relatively new to the style of patching... I have a T5240 with 4 LDOMS. A control LDOM and three clients. I have some fundamental questions I'd like help with..
Namely:
#1. The Client LDOMS have zones running in them. Do I need to init 0 the zone or can I just +zoneadm zone halt+ them regardless of state? I.E. if it's running a database will halting the zone essentially snapshot it or will it attempt to shut it down. Is this even a nessessary step.
#2. What is the reccommended reboot order for the LDOMs? do I need to init 0 the client ldoms and the reboot the control ldom or can I leave the client LDOM's running and just reboot the control and then reboot the clients after the control comes up?
#3. Oracle. it's running in several of the zones on the client LDOM's what considerations need to be made for this?
I am sure other things will come up during the conversation but I have been looking for an hour on Oracle's site for this and the only thing I can find is old Sun Docs with broken links.
Thanks for any help you can provide,
pipelineadmin+*

Before you use live upgrade, or any other patching technique for Solaris, please be sure to read http://docs.oracle.com/cd/E23823_01/html/E23801/index.html which includes information on upgrading systems with non-global zones. Also, go to support.oracle.com and read Oracle Solaris Live Upgrade Information Center [ID 1364140.1]. These really are MANDATORY READING.
For the individual questions:
#1. During the actual maintenance you don't have to do anything to the zone - just operate it as normal. That's the purpose of the "live" in "live upgrade" - you're applying patches on a live, running system under normal operations. When you are finisihed with that process you can then reboot into the new "boot environment". This will become more clear after reading the above documents. Do as you normally would do before taking a planned outage: shut the databases down using the database commands for a graceful shutdown. A zone halt will abruptly stop the zone and is not a good idea for a database. Alternatively, if you can take application outages, you could (smoothly) shutdown the applications and then their domains, detach the zones (zoneadm detach) and then do a live upgrade. Some people like that because it makes things faster. After the live upgrade you would reboot and then zoneadm attach the zones again. The fact that the Solaris instance is running within a logical domain really is mostly besides the point with respect to this process.
As you can see, there are a LOT of options and choices here, so it's important to read the doc. I ***strongly*** recommend you practice on a test domain so you can get used to the procedure. That's one of the benefits of virtualization: you can easily set up test environments so you cn test out procedures. Do it! :-)
#2 First, note that you can update the domains individually at separate times, just as if they were separate physical machines. So, you could update the guest domains one week (all at once or one at a time), reboot them into the new Solaris 10 software level, and then a few weeks later (or whenever) update the control domain.
If you had set up your T5240 in a split-bus configuration with an alternate I/O domain providing virtual I/O for the guests, you would be able to upgrade the extra I/O domain and the control domain one at a time in a rolling upgrade - without ever having to reboot the guests. That's really powerful for providing continuous availability. Since you haven't done that, the answer is that at the point you reboot the control domain the guests will lose their I/O. They don't crash, and technically you could just have them continue until the control domain comes back up at which time the I/O devices reappear. For an important application like a database I wouldn't recommend that. Instead: shutdown the guests. then reboot the control domain, then bring the guest domains back up.
3. The fact that Oracle database is running in zones inside those domains really isn't an issue. You should study the zones administration guide to understand the operational aspects of running with zones, and make sure that the patches are compatible with the version of Oracle.
I STRONGLY recommend reading the documents mentioned at top, and setting up a test domain to practice on. It shouldn't be hard for you to find documentation. Go to www.oracle.com and hover your mouse over "Oracle Technology Network". You'll see a window with a menu of choices, one of which is "Documentation" - click on that. From there, click on System Software, and it takes you right to the links for Solaris 10 and 11.

Best practices for ZFS file systems when using live upgrade?

I would like feedback on how to layout the ZFS file system to deal with files that are constantly changing during the Live Upgrade process. For the rest of this post, lets assume I am building a very active FreeRadius server with log files that are constantly updating and must be preserved in any boot environment during the LU process.
Here is the ZFS layout I have come up with (swap, home, etc omitted):
NAME                                USED AVAIL REFER MOUNTPOINT
rpool                              11.0G 52.0G    94K /rpool
rpool/ROOT                         4.80G 52.0G    18K legacy
rpool/ROOT/boot1                   4.80G 52.0G 4.28G /
rpool/ROOT/boot1/zones-root         534M 52.0G    20K /zones-root
rpool/ROOT/boot1/zones-root/zone1   534M 52.0G   534M /zones-root/zone1
rpool/zone-data                      37K 52.0G    19K /zones-data
rpool/zone-data/zone1-runtime        18K 52.0G    18K /zones-data/zone1-runtimeThere are 2 key components here:
1) The ROOT file system - This stores the / file systems of the local and global zones.
2) The zone-data file system - This stores the data that will be changing within the local zones.
Here is the configuration for the zone itself:
<zone name="zone1" zonepath="/zones-root/zone1" autoboot="true" bootargs="-m verbose">
<inherited-pkg-dir directory="/lib"/>
<inherited-pkg-dir directory="/platform"/>
<inherited-pkg-dir directory="/sbin"/>
<inherited-pkg-dir directory="/usr"/>
<filesystem special="/zones-data/zone1-runtime" directory="/runtime" type="lofs"/>
<network address="192.168.0.1" physical="e1000g0"/>
</zone>The key components here are:
1) The local zone / is shared in the same file system as global zone /
2) The /runtime file system in the local zone is stored outside of the global rpool/ROOT file system in order to maintain data that changes across the live upgrade boot environments.
The system (local and global zone) will operate like this:
The global zone is used to manage zones only.
Application software that has constantly changing data will be installed in the /runtime directory within the local zone. For example, FreeRadius will be installed in: /runtime/freeradius
During a live upgrade the / file system in both the local and global zones will get updated, while /runtime is mounted untouched in whatever boot environment that is loaded.
Does this make sense? Is there a better way to accomplish what I am looking for? This this setup going to cause any problems?
What I would really like is to not have to worry about any of this and just install the application software where ever the software supplier sets it defaults to. It would be great if this system somehow magically knows to leave my changing data alone across boot environments.
Thanks in advance for your feedback!

Hello "jemurray".
Have you read this document? (page 198)
http://docs.sun.com/app/docs/doc/820-7013?l=en
Then the solution is:
01.- Create an alternate boot enviroment
a.- In a new rpool
b.- In the same rpool
02.- Upgrade this new enviroment
03.- Then I've seen that you have the "radious-zone" in a sparse zone (it's that right??) so, when you update the alternate boot enviroment you will (at the same time) upgrading the "radious-zone".
This maybe sound easy but you should be carefull, please try this in a development enviroment
Good luck

Oracle 11.2.0.3 upgrade running on Solaris 10 using zfs/zones

Hello,
We currently run solaris 10 using zfs/zones.
We have a global zone and several sparse root zones.
The oracle upgrade (from 10.2.0.4 to 11.2.0.3) prerequiste check is reporting the following warnings:
OS kernel parameter "tcp_smallest_anon_port" plus 3 other warnings for tcp_largest_anon_port and for the udp ports as well
This requires that we use ndd to change the values for these ports in the global zone.
These changes will affect all of the sparse root zones and not just the one we are upgrading Oracle in.
Will this pose any problems or is safe to make these port changes in the global zone.
Thanks
Kevin

I would recommend you log an SR with Support

Upgrade from 8i to 9i using Database Upgrade Assistant

Hi
I installed 9i on a server that already has an 8i database. I am trying to use the upgrade assistant in 9i to convert the database to 9i. After selecting the 8i db, I get dialog saying 'Getting databse information. Please wait..' then error 'ORA-12560: TNS:protocol adapter error'. I tried setting the 9i listener to a different port (1522) and restart listener, no luck. Any suggestions?
Thanx

You need to try the database forum, whose ID i think is 145

NE2 upgrade disappointing. Can I use NE2 upgrade/discount again to exchange for new device?

I just used my New Every Two ("NE2") to upgrade from a Blackberry to the Droid Incredible 2. But frankly, the more I use the Droid, I more I don't like it. It's especially annoying when the battery drains after only an hour on standby. I need reliability, and this isn't it. Plus, it's loaded with apps I have no use for and can't get rid of. It's been a hell of a disappointment honestly since I so wanted to give the Droid a chance over the iPhone (reason being is that I already own several Apple devices including the iPod Touch (4th gen.) and the iPad 2 (WiFi + 3G).
I'd like to get the iPhone 4 instead. So here's my question: If I return my Droid within the 14 days (tomorrow is the 14th day, btw), will I get my NE2 opportunity back in order to apply it to the iPhone 4? I am not a new customer. I've been a loyal one for years, but somehow I think that wouldn't help in this matter.

Make SURE you return it within the 14 day window. You will have to pay a $35 restocking fee so don't be surprised when they charge you for that. But yes, this can be done easily. Just take it back to the store you got it at.

Can I upgrade Vista to Windows 7 (using an upgrade disk) on boot camp when my Vista drivers aren't functioning?

I have an early 2011 Macbook Pro and I'm trying to create a Windows partition. I have Windows Vista Ultimate, but apparently my computer can only support Windows 7 (I've tried everything to get drivers to work on Vista.) My question is, can I buy the $29.99 Windows 7 (shown here http://www.microsoft.com/student/en/us/windows/buynow/default.aspx) and upgrade my Vista, even though none of the drivers work? I can't afford to buy a full version of Windows 7, so I'm trying to work around it as best I can. Thanks so much for your help!

Cannot upgrade an AP to LWAP using the upgrade tool on Windows 7

Hello,
I have two Windows 7 computers and neither one will successfully upgrade a 1242 AP to LWAP. However, I go to a coworker's XP machine and run the tool without issues. On Windows 7 I keep receiving the error message of ACL or Firewall is blocking. I have added rules and then even tried disabling the firewalls completely on both computers and still no success. Help!
Thanks,
Kristen Woodard
Network Engineer II

As an aside here, if the AP are newer, manufactured after 6/2005(Has a MIC and not a SSC), you can do a normal archive download command to run the upgrade to the recovery image. Can even be scripted to run multiple times via shell/cron

ORA-06502 during a procedure which uses Bulk collect feature and nested tab

Hello Friends,
have created one procedure which uses Bulk collect and nested table to hold the bulk data. This procedure was using one cursor and a nested table with the same type as the cursor to hold data fetched from cursor. Bulk collection technique was used to collect data from cursor to nested table. But it is giving ORA-06502 error.
I reduced code of procedure to following to trace the error point. But still error is comming. Please help us to find the cause and solve it.
Script which is giving error:
declare
v_Errorflag BINARY_INTEGER;
v_flag number := 1;
CURSOR cur_terminal_info Is

I could not find the exact reason of error.
Please help us to solve this error.
Thanks and Regards..

Hello Friends,
I got the solution.. :)
I did one mistake in procedure where the loop should end.
I used the statemetn: EXIT WHEN cur_terminal_info%rowcount <= 0;
But it should be: EXIT WHEN Tab_Terminal_Info.COUNT <= 0;
Now my script is working fine.. :)

Solairs 9 Live Upgrade

Dear All
I am upgrading Solaris 8 to Solaris 9 using live upgrade on Sun Enterprise 450 Server . All the steps are completed but i am getting problem only while activating the boot environment of Solaris 9. Upgrading was successfully completed from Solaris 9 (1of2) CD . While i am activating the ABE for solaris 9 , it says that the upgrade is not completed and some packages still need to be installed and giving Error 142. If i continue upgrading from the CD (2of2) it is not accepting . Can anyone suggest how to complete the upgrade process so that i can activate Boot environment .
Thanks / Regards

Use remove SUNWXall then upgrade SUNWXall in your OS-Profile.

Live upgrade - solaris 8/07 (U4) , with non-global zones and SC 3.2

Dears,
I need to use live upgrade for SC3.2 with non-global zones, solaris 10 U4 to Solaris 10 10/09 (latest release) and update the cluster to 3.2 U3.
i dont know where to start, i've read lots of documents, but couldn't find one complete document to cover the whole process.
i know that upgrade for solaris 10 with non-global zones is supported since my soalris 10 release, but i am not sure if its supported with SC.
Appreciate your help

Hi,
I am not sure whether this document:
http://wikis.sun.com/display/BluePrints/Maintaining+Solaris+with+Live+Upgrade+and+Update+On+Attach
has been on the list of docs you found already.
If you click on the download link, it won't work. But if you use the Tools icon on the upper right hand corner and click on attachements, you'll find the document. Its content is solely based on configurations with ZFS as root and zone root, but should have valuable information for other deployments as well.

Hartmut

Live upgrade from solaris 8 to 10

how do i upgrade from solaris 8 to 10 using live upgrade on a sun netra t1 machine?

THere is a good intro to LU at
http://www.sun.com/bigadmin/collections/installation.html
beyond that, see docs.sun.com

Upgrading Sol 10 u3 x86 -- Sol 10 u6 x86 without using LU/Live Upgrade ?

Hi all,
I've got a group of SunFire x4200 M2 hosts currently running Solaris 10 x86 u3, fully patched. They are using the internal LSI Logic SAS controller in a RAID1 config for the disk environment.
When they were originally installed, the thought of running up an SVM mirror wasn't on the cards for our SE who installed them - nor was the potential for using Live Upgrade.
It occurs to me, that whilst Sun will release and continue to release patches for u3, I need to actually migrate to u6 in order to get certain functionality (i.e - new ZFS genesis, iscsitadm/iscsiadm, root zpools). I don't believe this will be "patched in" later for older versions, will it?
How can I cleanly upgrade my hosts without losing any config data or information? Is it even possible? These are production hosts, so I want to do this in the safest way possible. Many have told me I can simply slip in the Sol 10 update 6 media - and boot from it, then find that it will detect the old OS, but I am a little skeptical.
If someone could point me in the right direction here, that would be appreciated!
Thanks.
z

The installer polls many different things on the existing installation. If any of them aren't exactly right, it won't offer the upgrade option, and it won't give you any hints about what tests didn't pass. (Did I find a root slice, is there a root filesystem on it? Does the /etc/vfstab on that partition make sense? Do I have the space in those filesystems to upgrade? ...)
The most common ones to fail have to do with disk layout. It's possible to move /var around, or have an extra partition mounted that the installer doesn't realize is irrelevant for the upgrade.
If that's not the problem, it's very difficult to pin down. At one level, most of the installer logic is just scripts that you could read to understand the logic, but it's difficult to tell which script is running when, so following the logic is not easy.
