Two Middle Tiers - One Infrastructure

I have three windows servers. The first server is the infrastructure tier and the second server is the middle tier with Portal. I have installed a second middle tier with Portal on the third server and attached it to the infrastructure server that the first middle tier is using. However, Portal will not run. All other services are up except for Portal. Is it possible to have two separate middle tiers (one a development area and one a test area) that both connect to the same infrastructure server? If so, what am I doing wrong.
Thank you....Stacy

It was a walk in the park really...
Step 1 is to apply the 10.1.0.5 DB update to your infrastructure DB (that was the longest part). After that, you just run the OUI for 10.1.2.2 on the midtiers, and then the infrastructure before doing the MRUA.
Only kickers -
During 10.1.2.2 application, my midtiers were configured for http on 80 and https on 443 requiring that the .apachectl and webcache were owned by root. As a result, you'll get an error about writing to those files during the patch application. I just renamed the originals and clicked retry and the file was replaced with the new one.
Following that, you'll have to redo the web cache setroot script and reset the ownership on the .apachectl file to root again.
Other than that...no biggie

Install oracle10g AS 904 infrastructure and middle tiers on single node??

Hi
I will install oracle10g AS 904 infrastructure and middle tiers on single node.
I have some question.
1.install infrastructure and middle tiers must have different home_dir , It is mean use one user (EX:oracle) or two users (EX: infra and mid ) install ?
2. If use one user install , How to edit the user profile ?
3. If it install complete , Which em console do I start (infra or middle)??
4. Ple give the clear steps to install Infrastructure and Portal and wireless
on single host for AIX5L.
thank

Hi Kevin,
1. Create two seprate Oracle homes. Use the same user to install both.
2. Are you refering to changing ORACLE_HOME, etc?
3. Both. To save memory you can shut them down when you don't need them.
4. Use the quick installation guide. You can find it under documentation here on OTN.

Oracle Application Server Infrastructure & Middle Tiers?

Hi,
Can someone explain in simple words what is meant by Oracle Application Server Infrastructure and Oracle Application Server Middle Tiers and what the difference is between them?
Thanks!

That's right.
mainly there are two major groups of components in infrastructure:
- identity management (including Single-Sign-On, Oracle Internet Directory, Oracle Certificate Authority, some security schemas, etc), and
- metadata repository (which houses data even portal in the default installation if you have one)
middle-tiers run the applications. if you have java or OC4J applications, you will run them from mid-tier; or forms and reports or Business Intelligence, or portals & wireless, all would run from a midtier. but all will use infrastructure for a security, access (SSO), directory services, etc. you can have multiple midtiers connected to the same infrastructure too.

Hi! when starting my computer the background went gray with two hard drives in the middle. One is named macintosh HD and the other recovery 10.9. I have my whole life on my computer, and i don't know which of them i should start up? Please i need help!

Hey!

You probably held down the Option or Command R keys when you heard the startup tone. Simply choose the HD. To learn what the Recovery partition is please read OS X: About OS X Recovery

How to Configure Multiple Portal Middle Tiers with a Load Balancing Router

Hi,
Portal version trying to install 10.1.2 on Windows 2003 boxes.
I am following the guide http://download.oracle.com/docs/cd/B14099_19/portal.1012/b14037/cg_advnc.htm#i1046354. I have InfraStructure installed on a different box and am trying to install 2 Portal Midtiers each on separate boxes and using LBR. The above document is kind of confusing as I am trying to following
5.3.1 Step 1: Install a Single Portal and Wireless Middle Tier (M1)
5.3.2 Step 2: Configure OracleAS Portal on M1 to Be Accessed Through the LBR (AND FOLLOW ARE THE STEPS 1 to 14 in sequence)
if I follow 1 to 14 steps in sequence the information is not consistent what is being listed in the following sections
5.4.1 Create Virtual Hosts
5.4.2 Configure OracleAS Web Cache
5.4.3 Register OracleAS Portal with OracleAS Single Sign-On
i.e.
ptlconfig -dad portal -sso -host www.abc.com -port 7779
ptlconfig -dad portal -sso -host www.xyz.com -port 7779
as in the above steps it says to run
ptlconfig -dad portal -wc -site
and ssoreg command that always fails because I am running it from midtier as it gives error saying invalid username/password
as oppoesed to steps listed in point 8, 9, 10, 11 and 12.
Can someone please privide the steps in sequence I need to follow when installing 2 midtiers with frontend LBR and one infrastructure. I am trying to follow the architecture listed in the above link.
Any help is really appreciated.
Thanks

Hi,
Will appreciate any inputs on the following.
I am planning to install Infrastructure and one Midtier BI Forms Reports Discoverer, Portal on one windows box and the second midtier BI Forms Discoverer, Portal on the second windows box.
Please correct me if I am wrong on installing and configuring the mid-tiers as following are the steps I have compiled going through the document and want to make sure this time I do it right.
As I'll be installing BI Forms Reports Discoverer, Portal so wondering when I install the second midtier do I need to unselect all Portal, Forms, Reports, Discoverer or just the Portal I need to unselect.
Also in the host file of both the windows boxes do I just need to keep the LBR IP Address entry and remove the rest.
LBR:_
Computer Name: bigip5.prd.com
IP Address: *167.123.2.5*
Listen Port: *80*
Invaidation Port: *9401*
Infrastructure:_
Computer Name: portal1.prd.com
IP Address: *167.123.2.6*
Oracle HTTP Server Listening Port: *7777*
Application Server Control port: *1800*
M1 (Portal & BI Forms Reports Discoverer):_
Computer Name: portal1.prd.com
IP Address: *167.123.2.6*
Oracle HTTP Server Listening Port: *7778*
OracleAS Web Cache Listening Port: *80*
OracleAS Web Cache Invalidation Port: *9401*
OracleAS Web Cache Administration Port: *9400*
Web Cache Statistics port: *9402*
Application Server Control port: *1810*
M2 (Portal & BI Forms Reports Discoverer):_
Computer Name: portal2.prd.com
IP Address: *167.123.2.7*
Oracle HTTP Server Listening Port: *7778*
OracleAS Web Cache Listening Port: *80*
OracleAS Web Cache Invalidation Port: *9401*
OracleAS Web Cache Administration Port: *9400*
Web Cache Statistics port: *9402*
Application Server Control port: *1810*
First to create MetadataRepository and then Install Infrastructure and then follow the below steps to install Midtiers
Install and Configure of M1 (Portal and BI Forms Reports Discoverer):-_
*5.3.1 Step 1*: Install a Single Portal and BI Forms Reports Discoverer (M1 i.e. portal1.prd.com)
*5.3.2 Step 2*: Configure OracleAS Portal and BI Forms Reports Discoverer on M1 to Be Accessed Through the LBR
*1.* Configure LBR
*2.* Follow Section 5.4.1.1 to create the Virtual Host for bigip5.prd.com (LBR) and portal1.prd.com (M1)
*3.* Define a site that matches the virtual host entry for bigip5.prd.com (LBR) on Webcache of M1
*4.* Use OracleAS Web Cache Manager on M1, to map the site bigip5.prd.com (LBR) to middle tier portal1.prd.com (M1).
Follow steps 5 and 6 as per the document
*7.* Configure bigip5.prd.com (LBR) to accept invalidation requests from the OracleAS Metadata Repository on a separate port i.e. 9401
*8.* Change iasconfig.xml on M1
*9.* run ptlconfig -encrypt
*10.* Register the URL changes with OracleAS Portal by running ptlconfig -dad portal -wc -site
*11.* No need as it is http only
*12.* Run the follwoing
MID_TIER_ORACLE_HOME_M1\sso\bin\ssoreg.bat
-site_name bigip5.prd.com
-mod_osso_url http://bigip5.prd.com:80
-config_mod_osso TRUE
-oracle_home_path MID_TIER_ORACLE_HOME_M1
-config_file MID_TIER_ORACLE_HOME_M1\Apache\Apache\conf\osso\osso.conf
-admin_info cn=orcladmin
-virtualhost
*13.* Edit targets.xml to enable monitoring of the LBR's front-end host and port settings for OracleAS Portal
+<Property NAME="PortalListeningHostPort" VALUE=http://bigip5.prd.com:80/>+ and then run
MID_TIER_ORACLE_HOME_M1\bin\emctl reload
*14.* Test the setup
Install and Configure of M2 (Portal and BI Forms Reports Discoverer):-_
*5.3.4 Step 4*: Install a Single Portal and BI Forms Reports Discoverer (M2 i.e. portal2.prd.com)
*1.* As I am installing on wiondows so will not set IASCONFIG_LOC environment variable as I can just copy the iasconfig.xml file from M1 to M2
*2.* Run OUI on M2
*3.* Clear the selection for OracleAS Portal but don't know if I need to unselect Forms , Reports, Discoverer also.
*4.* Enable OracleAS Portal
*5.3.5 Step 5:* Configure the New Middle Tier (M2) to Run Your Existing Portal
*1.* Create both virtual hosts as done on M1
*2.* Copy dads.conf, oradav.conf, cache.conf, web.xml from M1 to M2
*3.* Re-register mod_osso on M2. To do this, perform the following steps by copying osso.conf from M1 to M2
*4.* Synchronize the DCM by using the following command
MID_TIER_ORACLE_HOME_M2/Apache/Apache/bin/ssotransfer MID_TIER_ORACLE_HOME_M2/Apache/Apache/conf/osso/osso.conf
*5.* Run dcmctl updateConfig
*6.* add the necessary mod_rewrite and mod_oc4j directives to the httpd.conf and mod_oc4j.conf files respectively
*7.* Restart Oracle HTTP Server on M2
*8.* Access the OracleAS Web Cache Manager on M1 and follow steps 9,10,11,12,13,14,15,16 for Webcache seetings and clustering.
Also will appreciate if can get some info on the following:
*1.*
When I configure the Webcache as per the Document but if I bring down one Midtier Instance the requests are not going to the other Instance that is up and ignores the case whether an instance is down. Any idea how what and where do I need to provide any setting which in case of instance is down routes the requests to the one that is up.
*2.*
What exactly happens when it says To enable monitoring of the LBR's front-end host and port settings for OracleAS Portal edit target.xml. Is this for LBR to find if an Instance is down or not and route the requests appropriately.
Thanks again for all the help.

Middle tier and infrastructure location

Hi ,
Does Middle Tier and Infrastructure tier should be on seperate Tier or can they installed on one Tier?
Thanks

They are normally kept separate for security reasons (and sometimes the middle tier is broken out into OHS and OC4J tiers too), though this will mean there are more servers to license.
If you do install both tiers on a single server be careful about assignment of ports (e.g. using staticports.ini) as this is the most likely thing to cause problems (I think there are various notes on Metalink and OTN).

Seperate ORASSO & OC4J_SECURITY in two different tiers

Hi,
Please refer the HA guide http://download-west.oracle.com/docs/cd/B14099_19/core.1012/b13998/selecting.htm#CJAIDIBJ
We are planning to seperate the OC4J_SECURITY and OHS in two different tiers thus avoiding database connection from web tier. is this possible ?
Similarly we want to put HTTP Server in the DMZ along with Web cache and OC4J_Portal in to a different tier. anyone tries this for 10.1.4 portal ?
1st tier :- web cache, OHS (1521 is blocked) DMZ
2nd tier :- Middle tier with OC4J containers
3rd tier :- OID, DB Hosts
Thanks in advance,

Gary,
You may certainly run OHS on one machine and OC4J on another. As you point out, this makes sense in a variety of deployments.
It is true, however, that OHS and OC4J will install together when you install 9iAS. But this does not mean that you must run both of them in your 9iAS instance. It is completely valid to run an OHS instance on one machine and configure it to dispatch servlet requests to an OC4J running on another machine.
For more information, you may want to take a look at the 9iAS Best Practices document. Specifically, look at the Deployment Best Practices section, which I believe starts on p. 95.

New AS Linux installation conflicts with outher middle tiers in production

I have a customer who installed AS 10g on Red Hat 3.0 with one house for infrastructure and another for middle tier. It is going out and discovering other middle tiers they have in production on Windows. It is causing port conflicts. OC4J and Forms keep stopping and restarting.
Any suggestions?
Thanks, Andy

Multiple Portals on One Infrastructure?

I am migrating (rebuilding not upgrading) several client portals from Portal 3.0.9 to 10g. In 3.0.9 I had several separate databases with Portal repositories in each database and each portal had a different DAD.
I have seen some posts which state that in 10g there can only be one portal repository per infrastructure and only one infrastructure per server. Can someone please confirm this and point to the documentation which states so?
I have read "Supporting Multiple Sites and Companies in a Single Portal Instance with Virtual Private Database" (Paper #32650). Sounds like the perfect solution to my problem. But what is the performance hit of deploying Virtial Provate Database (VPD) and virtual private portal? Has anyone actually deployed VPP, and has a story to tell?
Thanks,
Trenton

Thanks for the info. Here's a few more details. I
have two Linux servers with lots of RAM and disk
space. One runs the midtier and the other the
infrastructure. According to your post, I should:
1. Install multiple portal schemas (portala,portalb,
etc) to the existing asdb database using opca and/or
ptlasst (I assume these still exist in 10g).Trenton, We do support multiple DAD's per portal mid-tier and multiple portal schema's per database in Oracle Application Server 10g but only for upgraded portals, not for new portal installations. I strongly recommend NOT to use ptlasst in 10g to create multiple portal schemas in your existing asdb instance.
2. Associate each of these with the existing OID.
3. Install Mulple Oracle Homes on the Midtier server,
each associated with a different portal schema
(portala,portalb, etc) on the infrastructure server.
(Why not just different DADs in the same midtier?)
Do I have it right?Unfortunately not, the process I would recommend for 10g is:
1. Install one Oracle Database Home (either 9.0.1.5, 9.2.0.4 or 10g) using the Oracle database installer
2. Create multiple database instances using dbca (or your favourite method), one for your OID/SSO and one for each of your portal product metadata repositories (you can use the OID/SSO database for your first portal portal product metadata repository also)
3. Run the RepCA (Repository Creation Assistant) against all of these db instances to turn them into proper OracleAS Metadata Repositories
4. Install a second Oracle Home using the OracleAS 10g installer:
- Select a Product to Install >> OracleAS Infrastructure 10g
- Select Installation Type >> Identity Management
When you are prompted for a database use one of the existing db's you just created for your Identity Management DB (oid/sso/etc schemas)
5. Re run the RepCA -REGISTER (Repository Creation Assistant) against all of the db instances (except for the one you just chose as your Identity Management DB) to register them all with the OID service you just installed.
6. Install your your first portal mid-tier in a third oracle home using the OracleAS 10g installer and when prompted by the installer and wire it to your Identity Management services & First Product Metadata Repository (there will a pop-list in the installer for all the db's you just registered)
7. Install your your second portal mid-tier in a fourth oracle home using the OracleAS 10g installer and when prompted by the installer and wire it to your Identity Management services & Second Product Metadata Repository (there will a pop-list in the installer for all the db's you just registered)
8. Install your your third portal mid-tier in a fifth oracle home using the OracleAS 10g installer and when prompted by the installer and wire it to your Identity Management services & Second Product Metadata Repository (there will a pop-list in the installer for all the db's you just registered)
9..and so on...
I'd appreciate a look at your
draft whitepaper if that would help. It's only applicable for people who are performing an upgrade, not a rebuild or new install of 10g so it wouldn't really help you.
Compared to the
VPP solution how would this solution be for
administration, CPU intensity, etc.? Also since all
portals would share the same OID/SSO server, would
there be a problem with the client user administrator
seeing the users of other clients?
In general I would not recommend using VPP as this setup is not widely used and is quite specialised.
Thanks Again,
TrentonHope this helps,
Mick.

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?

Actually, everyone missed one point, when a device is priced, the cost of icloud storage space for that device is also included in it that is why they are able to give you 5gb each for each user ID, in nutshell there is nothing free coming with apple device purchase, it is paid for. What they are trying by giving only 5gb per user ID irrespective of the number of devices used is pure broadlight looting, they take money from you when you buy each device and give you nothing, This is a case of goods and services bought but not fully deliverd ie apple can be suied for discreminatory treatment towards it's users. I wonder why no one tried this yet in America where everyone sue everyone for petty things..... there is no one to take up this issue? . if tim got any love for the guys who shell out money for the devices his company makes, he should be implimenting this as priority before someone wake up from sleep and sue him.

I have a 3 year old MacBook Pro with MAC OSX 10.6.8, iPhoto ’09 version 8.1.2 and have downloaded two software programs: one is Aperture 3.2 and the other is Photoshop Elements 9 (which I got from a friend who didn’t need it).
I am totally happy with the way iPhoto organizes my photos and how I can work with iMovie to create slide shows with music from iTunes, etc.
I have been shooting mostly high resolution jpegs and I continue to learn more and more about photography, post processing etc. I realize that the small adjustments I can make in iPhoto are good, and are adequate most of the time. However, a have started to experiment with shooting RAW images and would like to go the next step, ie. post processing.I am totally technically challenged and need SIMPLE, INTUITIVE programs and am certainly NOT anywhere ready for Photoshop CS whatever!
After having these programs sit on my computer, I decided to try to see if I could figure them out. When I opened Aperture, this is what first comes up.
“Welcome to Aperture 3.2
Your library needs to be upgraded to work with this version of Aperture. Once upgraded, you will not be able to use this library with previous versions of Aperture.
Upgrading a library from previous versions of Aperture 3 generally takes a few minutes or less, though larger libraries will take longer. After that, Aperture 3.2 will upgrade your library's thumbnails, but you can use the application during that time.
Tip: To open a different library, quit Aperture and hold the Option key down while starting Aperture
Current Library Location:
Jadzia (home) -----Pictures------Aperture Library
QUIT UPGRADE”
I have heard horror stories about moving your entire library to Aperture, ending up with 2 libraries, etc. etc. hence my previous reluctance in attempting Aperture. In addition, many of my photography friends are saying: Go with Lightroom 3.....you’ll love it!
So here is my dilemma. I don’t want to mess around with my iPhoto library. All I want to be able to do, is to isolate a few photos, export them to Aperture, Elements, and work on them there, then bring them back into iPhoto.
Can I do this? Should I forget about Aperture and Elements and look at purchasing yet another program like Lightroom?

Export those few photos via the File ➙ Export ➙ File Export menu option with Kind = Original to the Desktop. Then import them into the Aperture library. That would keep one copy in your iPhoto library and another in your Aperture library to edit, etc.
You can use Photoshop Elements 9 from within iPhoto as your editor of choice. However, if you edit a raw file in iPhoto with PSE9 the resulting edited version must be saved outside the iPhoto Library and imported back in as a new file. For editing jpegs just do a Save (not a Save As) and it all will be kept within iPhoto.
Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.
1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.
3 - however, if you get the navigation window
that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
NOTE: With Photoshop Elements the Saving File preferences should be configured as shown:
I also suggest the Maximize PSD File Compatabilty be set to Always. In PSE’s General preference pane set the Color Picker to Apple as shown:
Note: to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.

Jim,
Before starting the database A, did you set ORACLE_SID=A from command line? You can run as many instances you want from single server provided you enough memory, processing power. Also try starting your instances usign window services and check and post some lines from alert.log for database A.

About combing two array into one

Hi all,
I post a questiona bout converting an array of integer into char (byte) array and I got a solution already http://forums.ni.com/t5/LabVIEW/how-to-display-char-code-properly/m-p/2596087#M780368
However, I enouther another problem while dealing with an array of U16 type. I would like to extract the high and low byte from numbers (U16) stored in array. I extract the high and low byte for each U16 number and convert them as char, concatenate them to a string. Repeat this process for each element in the array so to get a big string with each element is a char for high and low byte. My code is enclosed as follows
It works fine but I am concerning the speed. Is that any other way to do it fast and don't use loop (in real case, I will deal with pretty big array many times, efficiency is a problem). Note that the high and low bytes array extracted from the original array with the module Split number.vi, but how can I combine these two array in one code with data arranged as high-low-high-low ... ?

You need to be more clear.
Looking at the code, you are dealing with I16, not U16. Also your index array primitives could be replaced by autoindexing. Your use of the feedback node only makes sense if you want to append strings forever with stale data, thus growing data structures without limits. If you only want to convert the current data, remove the feedback mode and use a "concatenate strings" with a single input. A for loop is one of the most efficient data structures and using it is not a problem. One way or another the code needs top oerate on all data.
All that said, I agree with Tim that most likely all you need to do is insert a typecast after the "to I16" and eliminate all other code.

Hi. I am having an issue with music on my IPod. It would probably be easier to explain my specific issue: I have songs by Band of Horses from Cease to Begin. When viewing my albums through cover flow, it shows Cease To Begin as two separate albums, one with only Islands on the Coast, and the other having Islands on the Coast with 3 other songs. If I delete the album with only one song from my IPod, it deletes the song from the other "album" as well. If I go to "All Songs" by Band of Horses, it only shows one Islands on the Coast, so it is not a duplicate issue. Also, in Itunes, it only shows one album. I just recently updated to iOS5 on my 4th Gen IPod Touch, if that helps.
