Building 3 tier setup from 2 tier

Hi Gurus,
My objective is to migrate my existing application which is developed using forms5 and reports3 to 10g.
This is the first time i am getting in to 3 tier setup, that is why I need help in setting up the Oracle Application Server to run forms and reports in 10g
I installed developer suit 10g (forms and reports) on a desktop of win xp. My oracle database9i rel2 is on win2003 32
bit server, I had kept another win2003 32 bit server ready for Oracle Application Server 10g (Even I have windows ISA server running on win2003 32 bit
server).
I have all windows 2003 servers and most of the clients are WinXP and some are Win7 prof.
Hope this information would give some idea about my problem... please suggest me how to go ahead
Thanks in advance

Thanks to all of you Gurus...
In the forms upgrade it is mentioned that versions prior to forms6 can't directly migrate to 11g, they have to migrate from 5 to 10g then 11g.
I think database can be 9i or 10g, hope will work with forms10g as my current live database is on 9i so i dont want change now.
only thing I am not able to understand is where to install oracle application server, does it requires a dedicated win2003 server or it can be on any desktop which we use for development of forms and reports? then how to install and where my .fmx/.rpt will be? how to call a form from a client? Is there any thing much/complicated to setup at oracle application server?
and now a days I am hereing lot about oracle application server has became weblogic server, changed the name from 11g... am I right? please correct me if I am wrong
Thanks again to all my Gurus...

Spring/Hibernate tier called from Java Stored Procedure

Here is my scenario.
Building out a new physical model alongside an old db.
Two schema's inside same Oracle instance.
We are building a new Java tier on top of the new schema using spring/hibernate.
To maintain sync with the old db we are building a load of PLSQL code that will be called by PLSQL stored procs on the old schema.
====
Now it occurred to me that if I could put a copy of my new java tier in the database itself then the trigger code on the old schema could call a java stored proc wrapper which in turn called into my new java tier inside the instance.
This way I avoid duplication business logic in the db sync and the java middle tier. Basically I do away with the PLSQL sync code and just use the new java component.
This clearly has advantages from an automated testing point of view too.
So very interested in how/if anyone has made this work.
Potential issues...
- JVM version (outside the db we use Sun Java 5 - inside the db I'm not sure what is used).
- How would spring access it's config files?

You asked:

You also asked:

- JVM version (outside db use Sun Java 5 - inside db not sure)
- How would spring access it's config files?
Oracle has its own JVM embedded in the database: OJVM
In Oracle 8i it is compatible with JDK 1.2
In Oracle 9i it is comaptible with JDK 1.3
In Oracle 10g it is compatible with JDK 1.4
You can access files outside of the database from OJVM, you just need to set correct permissions.
Perhaps Kuassi Mensah's book, Oracle Database Programming Using Java and Web Services will be of help?
Good Luck,
Avi.

Demand Forecast to rollup from Tier 3 warehouses to Tier 1 main plant

Hi ,
I would like to find out if there are any possibilities to roll up demand forecast from Tier 3 warehouses (nodes) upwards to
main Tier 1 warehouse / plant (root)
please suggest ideas/ inputs
1)Any BI Data Load methodology need to changed or if
2) Any APO config needs adjustment

HI,
I am now confused on what you actually want to do.
If you want to plan in SNP, then since you are maintaining inforecords in ECC, you need to create integration models in ECC and CIF the inforecords. Each inforecord should come into APO and create transportation lanes. You shouldn't have to manually create transportation lanes in APO. You would how ever need to maintain the means of transport in each of the lanes from plant to DC Tier I to DC (s) Tier3.
When you run Heurisitics, the demand is aggregated to Tier I DC and then to plant.
If you maintain the forecast for the Tier I DC and Tier II DC(s) in DP, you can just release the forecast at these DC levels.
If you want to run statistical forecast at the Tier II DC(s), then you need the demand history in DP for each of the DCs.
Is this what you are trying to do? or are you trying to rioll up demand in DP. If you want to roll up demand in DP, I am not sure what the need is. Can you explain?
For any further questions, please give more details; examples would help.

How to copy app tier directories from node to node?

Hi.
The documentation for this cloning process, p5 of https://metalink.oracle.com/metalink/plsql/f?p=130:14:5320863338933915562::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,230672.1,1,1,1,helvetica
suggests that we "copy the following application tier directories from the source node to the target application tier node"
What is the UNIX command for this type of copy? I did ask our DBA yesterday, and he told me he would explain. That was yesterday and I am still waiting...
Thanks for any help.

Upgrade from a two tier EBS 11i 11.5.10.2 on Windows 2003 Apps and Windows 2008 R2 DB tier to two Tier R12.2.3 both on Windows 2008 R2

Hi,
Any ideas about the best practices for the migration/upgrade reflected with the below question?
I have a source EBS11i 11.5.10.2 running as a two tier configuration ( apps tier on server ora10 on Windows 2003, DB tier 11.2.0.2 on server ora1 on Windows 8 R2. Can I use the Note 1377213.1 for a migration to a two tier configuration ( apps tier on server T10 running Windows 2008 R2 and EBS 12.2.3 and DB tier running 11.2.0.4 on Windows 2008 R2 )? What alternative approach could you suggest? As far as I know EBS11i is not certified on Windows 2008 R2 and R12.2.0 is not certified on Windows 2003.

Yes you can by following "Application Tier Upgrades and Migrations" section -- Install 12.2 apps tier on 64-bit Windows and proceed with the upgrade.

Webi Rich Client 2-tier Vs 3-tier?

Could anyone explain what is 2-tier and 3-tier for Rich Client?
Thank you

When you login 3-tier will show a web app (j2ee or .net) in the system information, as it must connect to the connection server through the web/app. It will use the XI 3.x servers middleware connection for refreshing report data.
If you launch it from infoview a file will be created on your local computer called something.extranet and this file will contain the web/app connection information for connecting.
When using 2 tier connections will be made from the local computer, this requires middle ware to be set up on the workstation(s). Performance will be faster in 2-tier as a benefit. When using 2-tier only a CMS or clustername will be entered in the system.

Tim

Has anyone implemented ChaRM in a 4-tier or 5-tier landscape?

Iu2019ve setup ChaRM with a 3-tier landscape DV1-QA1-PRD and everything works as advertised. I used the transport route, DV1/120 -c- /QA1/ (clients 149/150) -QA1 -d- PRD/150. Where -c- is a consolidation route and -d- is a delivery route.
Now I need to do a proof of concept to see if I can get CHaRM to work with our current landscape. We have a dual development path and need to make sure we sync our DEV and QA systems. The lanscape Iu2019m trying to use is DV1-QA1-PRD-DV2. The transport route Iu2019m trying is DV1/120 -c- /QA1/ (clients 149/150) -QA1 -c- PRD/150 -d- DV2/120. Iu2019ve tried various combinations and the only way I can get it to work is DV1/120 -c- /QA1/ (clients 149/150) -QA1 -d- PRD/150 -d- DV2/120. When I release and import into PRD it goes to both PRD and DV2. While this gets the transport to my support dev box I need to have another step in the workflow. What Iu2019m looking for is the workflow to act like dev-qa-qa-prd.
Has anyone setup a 4-tier or 5-tier landscape with release and import steps between each system? If so what did you use for your transport route and were they other config changes needed after the route?
Thanks for your time.
Jeff

Oracle E-Business Suite 12.1.3 App Tier and DB Tier in US-West region

Hi,
We need to setup 12.1.3 Vision instance on Amazon EC2. When I am checking details on AMI (Amazon Machine Images) for Oracle E-Business Suite 12.1.3 App Tier and DB Tier, I see below
“This AMI is currently available for use in the US-East region and for the High-Memory instance family (m2.xlarge, m2.2xlarge, and m2.4xlarge)”
Does it mean we can’t use it for US-West region? I could not find any phone number to contact AWS sales person.
we need to setup instance this week for client's demo. Appreciate quick response.
Thanks,
Jigisha

Hello
See the logfiles adwork001.log to adwork004.log. The last lines show the errors ocurred. The best thing to do is to open an SR with Support sending those error messages.
Hope this helps.

Report Generation - Build an exe from a PC with different Office Version

Hi,
I want to build an exe from a VI that uses Report Generation Toolkit. The application has to be deployed on several PCs that use Office 2000. During development phase I installed on my PC, Office 2000 and everything was ok. After I was done with it, I reinstalled Office 2007. So, the Report Generation Toolkit from my PC is for Office 2000 (it was installed when I had Office 2000 on my PC).
These days I had to fix some bugs from my application, I made a new exe but the part that generates Word reports (using RGT) is not working anymore - I received that error with -35...9935 (or something like this).
I tried to search for the problem and I found it: with exactly the same VI's (_Word Dynamic VIs.vi - for Office 2000) the invoke nodes from a PC with Office 2007 and a PC Office 2000 look different. For example in Word_Open_Document.vi, the invoke node Document is different for a PC with Office 2000 + RGT for 2000 and a PC with Office 2007 + RGT for Office 2000 (no mistake).
So, I've tried to copy the VI's from a PC with Office 2000 + RGT 2000 to my PC but I cannot build it because I get the error: There are some errors in _Word Dynamic VIs.vi (the invoke nodes do not fit).
Finally my question is: How can I build the exe on my PC: Office 2007 but with RGT for Office 2000??
Thanks,
Paul
Solved!
Go to Solution.

Hi,
Thank you for your advice. Can you please tell me what you want to say with the wrapper vi? I don't really understand what you mean.
By the way, I solved the problem. I discovered that the Invoke Nodes are updated based on the Object Library for the ActiveX control (in this case the MS Office). The data types are store in the msword9.olb (version 9 - for office 2000 in Office folder) and msword.olb (version 12 - for office 2007 also in Office folder). I tried to register the msword9.olb (using the regsvr32.exe) but it doesn't work for olb files - I need the ocx or dll. But, if I replace the msword.olb from Office 2007 with msword9.olb from Office 2000 everything work.
Ok, steps that have to be done:
1. Install the RGT for Office 2000 on the PC
2. DO NOT Change anything in _Word_Dynamic VIs.vi. When Office 2007 is installed the VI arrow should be broken (error in VI)
3. Copy the msword9.olb from a system with Office 2000 (or your version) and copy it to your system with Office 2007 with the new name msword.olb. DO NOT FORGET to make a backup of the original MS Office 2007 file and to restore it at the end.
4. After the new msword.olb is there, the _Word_Dynamic VIs.vi should have no error
5. Build your exe application
6. Restore the old msword.olb
7. ENJOY your life !
I hope this is useful also for somebody else.

Error while building an executable from vi

Hello,
I am trying to make a .exe file from the VI which includes Vision Aquisition Software also and while building it I get a error message--
Error 1502 occurred at AB_Source_VI.lvclass:Close_Reference.vi -> AB_Build.lvclass: Save.vi -> AB_Build.lvclass:Copy_Files.vi -> AB_Application.lvclass:Copy_Files.vi -> AB_EXE.lvclass:Copy_Files.vi -> AB_Build.lvclass:Build.vi -> AB_Application.lvclass:Build.vi -> AB_EXE.lvclass:Build.vi -> AB_Build.lvclass:Build_from_Wizard.vi -> AB_UI_Frmwk_Build.lvclass:Build.vi -> AB_UI_FRAMEWORK.vi -> AB_Create_Build_Application.vi -> EBUIP_Global_OnCommand.vi -> EBUIP_Global_OnCommand.vi.ProxyCaller
Possible reason(s):
LabVIEW: Cannot save a bad VI without its block diagram.
Can anyone tell me how to solve this problem ?
Thanks in advance.

I had done that and did not work. I did not get rid of the old build defination, but started a brand new one via Tools>Build Application (EXE) from VI... I got the same error 1502. Inspecting the offending VI did not yield any obvious problem with the block diagram.
Upon searching for error 1502, I found this Know Issue link:
http://www.ni.com/white-paper/11869/en. Issue ID 255617 stated:
Error 1502 can occur if dependencies are placed in non executing case structures
In previous versions of LabVIEW you could place VIs in a case structure with a constant wired the the case selector. This would load the VIs at runtime. If you have this pattern and attempt to build an executable you could receive error 1502
Workaround: Don't use unreachable code
So the issue is I have an case structure with hard coded boolean, so the other case is unreachable.

2-tier or 3 tier?

i hava webapp like this jsp--> dao (singleton) --> hibernate -->database (is this consider 2 tier or 3 tier?)

DAO = Data Access Object. Given the first word in that acronym, I think we can comfortably put this at the Data layer.
Right now I'd say you have 2 tiers there.
The 3rd tier is normally another layer sitting between your Server and your database. EJBs for instance.
Client
Tier 1 = Web server.
Tier 2 = application server.
Tier 3 = database server
Client talks to web server over http. Web server talks to application server (RMI, EJB, whatever). Application server talks to database.
If your architecture comprises of just Tomcat and a Database, you've probably got 2-tiers

Differcence between 2-tier and 3-tier

hiii,
diff between 2-tier and 3-tier sap architecture??

The easiest way to explain this is, as you suggest, by an example. So I'll give you an example.
Let's suppose I'm going to write a piece of software that students at a school can use to find out what their current grade is in all their classes. I structure the program so that a database of grades resides on the server, and the application resides on the client (the computer the student is physically interacting with).
When the student wants to know his grades, he manipulates my program (by clicking buttons, menu options, etc). The program fires off a query to the database, and the database responds with all the student's grades. Now my application uses all this data to calculate the student's grade, and displays it for him.
This is an example of a 2-tier architecture. The two tiers are:
1. Data server: the database serves up data based on SQL queries submitted by the application.
2. Client application: the application on the client computer consumes the data and presents it in a readable format to the student.
Now, this architecture is fine, if you've got a school with 50 students. But suppose the school has 10,000 students. Now we've got a problem. Why?
Because every time a student queries the client application, the data server has to serve up large queries for the client application to manipulate. This is an enormous drain on network resources.
So what do we do? We create a 3-tier architecture by inserting another program at the server level. We call this the server application. Now the client application no longer directly queries the database; it queries the server application, which in turn queries the data server.
What is the advantage to this? Well, now when the student wants to know his final grade, the following happens:
1. The student asks the client application.
2. The client application asks the server application.
3. The server application queries the data server.
4. The data server serves up a recordset with all the student's grades.
5. The server application does all the calculations to determine the grade.
6. The server application serves up the final grade to the client application.
7. The client application displays the final grade for the student.
It's a much longer process on paper, but in reality it's much faster. Why? Notice step 6. Instead of serving up an entire recordset of grades, which has to be passed over a network, the server application is serving up a single number, which is a tiny amount of network traffic in comparison.
There are other advantages to the 3-tier architecture, but that at least gives you a general idea of how it works.
Incidentally, this website is a 3-tier application. The client application is your web browser. The server application is the ASP code which queries the database (the third tier) for the question-and-answer you requested.
I hope that helps! dont forget to give points if useful

Application builder icon disappeared from database home page

i am wondering , is APPLICATION BUILDER ICON removed from database home page of all users or just mine. please i need help here..

Do you mean the icon display, or the ability to use the app identified by the icon?
(If just the display (it shows the empty box), there is a known problem with some images appearing broken. In which case, you can try forcing a reload form the server by adding a 'Shift' to your reload command (eg: use Shift-F5 in I.E. or Shift-Ctrl-R in Firefox)
