Infrastructure for installing advanced features like RAC, ASM and DataGuard

I have been working in Oracle for an year now and would like to start working on advanced features like ASM, DataGuard and RAC. Currently I use a 32bit laptop with OEL6.3 installed with 4GB RAM. Is this system sufficient to install and practice ASM, DataGuard and RAC. To be more specific I would like to know whether 32bit would suffice OR I need a 64bit system for this?

I'd say you are pushing it.
These features are usually used in multi-server environments.
You could work with multiple VM's, but 4 GB sounds very limited.
I had a quick look at introduction to the Data Guard Hands On Lab, and it seems it's hosted in the Amazon Cloud.

RAC, ASM and Dataguard compatibility

We have a Dataguard setup with 3 node RAC. The primary is a 3 node RAC but the standby is a single instance. The ASM version is 10.1. Currently we have switchover the roles.
Can upgrade the ASM to 10.2 on standby then make it primary?
All I want to know is if we can have ASM 10.2 on primary and ASM 10.1 on physical standby?

The note for latest ASM [ 10.2 ] indicates a level of backward compatibility I believe
What version is the database ?

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.
When I mouse over the icons, the rainbow appears as if it was processing something. The problem is eliminated when I restart my computer but it comes back after a while.
I guess I cant make a backup copy and restore the whole disk because the copy would be made with this error.
Can anyone help me? Anyone with the same issue?

Update: I was able to test out the HDMI adapter as well and the same issue occured. I'm stumped. 10.8.1 maybe.

Hi I am currently have a subscription to PS CC but I don't think I have the latest version. I believe this because I don't get the new welcome screen and don't have new features like the structure and color setting in the content aware patch tool. I have checked for updates and it tells me I have the current version. I check in PS I have version 14.2.1. I also have CS6 installed on my PC, could this be somehow be doing something or am I doing something wrong. Would anyone have any suggestions.

It's under "Find New Apps". You have to scroll down to see it.

Best Practices for highly dynamic features like Search

For a project I need to implement a "Search" Component which will most probably use lucene that is built into CQ5. Since most of the other content on the site is dynamic and cached on dispatcher my concern is regarding the load such a dynamic feature will create for the publish instance.
What are the best practices to minimize the load on publish instance for such a scenario?

One option is to have your search results display via AJAX rather than a full page request. That way most of the page is cached in dispatcher and only the AJAX request with the search results is dynamic.

Best Practice for installing/managing 9i/10g RAC

Looking for this notes/articles...

There is one best practice document available from Oracle RACSIG site and "Oracle Real Applicaiton Cluster Administration and Deployment Guide" available on OTN is also good source of informaiton about 10g RAC.
Oracle has made sincere efforts in 10g documentations expecially in server technology.
Thanks & Regards

11gR2 RAC, ASM and database

Hi all,
I've installed 11gR2 RAC and database on Linux OEL 5.4. Everything seems Ok, I'm able to connect from client using SCAN, and load balancing works well, but "crs_stat -t" shows up some OFFLINE services, like gsd and oc4j.
Is this normal ? If yes, why it's so ? If not, what should I do to solve the problem ?
Thanks in advance.
Antoine

Thanks for your answer.
Those services are disabled, and I've found this one on MOS FAQs :
With Oracle Clusterware 11g Release 2, the GSD resource will be disabled by default. You only need to enable this resource if you are running Oracle 9i RAC in the cluster.

10.2.0.4 to 11gR2 with RAC, ASM and replication

I have two systems needing to be upgraded. These two systems are both a 2-node RAC on solaris 64 bit using ASM. We use multi-master replication to keep the two systems in sync.
One goal is to have little or no downtime... ( a few minutes might be ok).
One thing that could possibly happen is that we are getting a new hardware to host one of the system and it could already have 11gR2 on it so it might just be a simple export/import. but for the other system in the replication scheme i'd need to get that upgraded.
Can i use replication two keep my downtime to a minimum? for instance, i could have replication on one system queueing up the changes. Once the other system is upgraded turn it back on and get the two systems synced up via replication. So kinda of like this..
system 1 with 10g
system 2 with 10g (current users pointing here)
introduce new system with 11g to replace system 1.
can the changes queued up on system 2 then get propogated to the new 11g system?
and if yes can i then switch users over to the new 11g system, upgrade system 2, then propogate the changes queued up in the new 11g system to the upgraded system 2?
any other advice would be helpful. I haven't seen anything about how replication is effected with the upgrade.
thanks...

Simple ruleset for ufw - advanced users welcomed to read and review

Since tcp_wrappers is now flushed, I think it's time to add a firewall
I have a very simplistic setup here and want to make sure I'm understanding this applications. My goal:
1) Allow incoming "LAN" traffic (all ports/protocols from machines in my subsnet). This will encompass services such as CIFS, Samba, Printing, distcc, etc. etc.
2) Allow incoming bittorrent traffic from the entire Internal via the [Deluge] preset
3) Allow incoming ssh connections from the entire Internet AND allow port forwarding therein. I access my machine via tunneling through ssh.
# ufw default deny
Default incoming policy changed to 'deny'
(be sure to update your rules accordingly)
# ufw allow from 192.168.0.0/24
Rules updated
# ufw allow Deluge
Rules updated
# ufw allow SSH
Rules updated
Is this it? Do I need to worry about localhost or 127.0.0.1 to facilitate the port forwarding? For example, vnc only accepts connections from 127.0.0.1 since again, I tunnel into it from outside the LAN. I do the same from my lighttpd.
# ufw status
Status: active
To Action From
Anywhere ALLOW 192.168.0.0/24
Deluge ALLOW Anywhere
SSH ALLOW Anywhere

I believe only files in the backups array are spared.
Yup, this was spot on. I've created a ufw-custom file and just appended My to the front of each identifier, MySamba, MySSH etc.
[MySamba]

Just ufw, make sure you
#ufw enable
before you do though.

TS1702 i was looking for install imessageapp on my iphone 4 and i didnt find it. is it temporary issue or something else ?

i have a problem downloading and installing imessageapp to my iphone 4

It is not a separate app. It is the messages app that's part of iOS.

Im getting a grey box at the bottom of my screen under the display line for the add ons like ghostry,personnas and greasemonkey icons are . i cant seem to get a "full screen" anymore . can you tell me how to overcome this

the box is located under the icon line at the bottom of the screen and above the window tool bar/icon box ! its almost like im running in a wide screen mode ! i cant seem to find a way of making the screen deeper, so it fills all the available space ! its also . freezing and it messes with the add ons and the adobe plugins ! a real shame cause i think the new layout is great . kep up the good work

Do you have that problem when running in the Firefox SafeMode? <br />

ASM and Dataguard

Hi,
can we make asm database (i.e. database is managing by asm disk groups) as primary database in one server and configure secondary database in another server.

Hi,
If I understand your question, you are asking if you can have the following on the primary...
+ASM/DB_NAME/DATAFILE/system01.123.456.789
...and the following on the standby...
/u01/app/oradata/DB_NAME/system01.dbf
...on the standby?
Yes you can. Look into db_file_name_convert and standby_file_management in the documention at tahiti.oracle.com.
HTH,

Creating Standby for RAC ASM database using RMAN

We are having a Primary Site of 3-Node RAC ASM and we takes daily RMAN backup with the following script
run
allocate channel c1 device type disk format 'g:\rmanbackup\%U';
backup database;
backup archivelog from time 'trunc(sysdate-1)' until time 'sysdate';
We have configured 3-Node RAC Cluster in Standby site. We have copied the rman backup folder to one of the Nodes in the Standby site.
Request your help to restore the RMAN backup. The backup size is around 200GB. We do not know how to use DUPLICATE DUPICATE option in RMAN as if it is restoring from the Primary Location, then transferring 200GB over the network will not be possible.
We need a solution to restore it directly from the Backup folder available in the DR Server. We are not using catalog.
OS : Windows IA 64-bit
RDBMS : Oracle 10.2.0.4
Storage : ASM
DB Nodes at Primary Site, Node1, Node2, Node3
DB instances at primary site : ORCL1, ORCL2, ORCL3
DB Nodes at Standby Site, Node101, Node102, Node103
DB instances at Standby site : ORCL1, ORCL2, ORCL3
DB Name : ORCL on both the sites.

When you create the standby, you can use catalogued backups, stored somewhere local to your standby servers.
For that, they need to be copied to the standby server, or taken from production there, and after restoring the standby controlfile on the standby server, use rman to catalogue the backups to be used. Then, you can use DUPLICATE... and it will be reading your local backup files.
The directory g:\rmanbackup of your rman script is local to standby servers ?
The docs for this have a lot of details: http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rcmbackp.htm

Has adobe adopted the compound math feature like quark has in its interface.

I am currently working with CS3. Has adobe adopted the compound math feature like quark has in its interface.
For instance If I want to duplicate an item 29/6" vertically but I know that that step should be 1/8" short, in quark I can type 29/6-.125, or 29/6-1/8. Either method will give me 4.708333. Same issue when I just want to draw a box a specific size minus or plus 15/64 or an inch. Adobe forces me to look up the decimal equivalent before I enter it or I will get the message: "INVALID NUMERIC VALUE"
This applies to all adobe products I use.
This really slows production down and I hope CS5 allows this now.

Seriously Bob, Seriously. Quark has had this feature for 20+ years.
Quick, do the following, draw a box or a line or anything.
Now move it to here.
2.0416 in +3/64 -7pt -3in -9.7mm
I can type this verbatim in qxd and end up with what I want, I CANNOT do this in any adobe product that I currently use.
There is nothing wrong with my attitude, this is a feature that I use daily in my work and having indd and ill require me to look up decimal equivalents of inch fractions is not productive.
If my priorities do not match your priorities why does that make mine a total mess?
Oooh Gotchew on that one. Gotchew on that one. You have no answer for that.
"Hard to believe all the cool stuff you still can't do with Quark, too."
I don't like one app over another I use both daily but indd seems more stable. If you want to argue Toyota vs Chevy, go ahead. I think one software company should look at competing products and implement functionally positive features in their own.
I suppose to carry my analogy further, Adobe may have added nice features like a sunroof, and power windows but has not added power steering like their competitor has had for 20+ years. I really don't use the "Cool Stuff" in the products I manufacture.
I will waste no more time here and will simply flood the company with this feature request as I have been doing.
