How to use one application with multiple schema without copying application?
Hi,
Previously we are using oracle forms and by that we can manage by using a set of folders containing fmx and use different schema/database for different customers. so the source code comes from one individual file but used for different database users.
is it possible to do this without copying application in apex?
reason is because if applications are copied for each customer, and in a situation where a page has a bug, the developer must correct multiple pages across all the application. This would not be appropriate to manage.
could this be done in apex? or is there any other approach?
Hi,
An application is tied to its parsing schema, so it is not possible to have one code base which you can then point to different schemas. I have seen some threads relating to dynamically setting the parsing schema, but I don't think it has worked to well, and would not be a supported configuration by Oracle.
The normal way to do this is to have one schema and for each entity where it is logical you will have an extra key which is the customer id. I mention where it is logical, because not every entity needs its own data defined by customer. Some data will be common across all customers, such as lookup data and some entities will comprise child entities by which the data separation will be implied by the parent. You can then use Oracle's Virtual Private Database feature to implement a seperate view of the data through the application, based most likely on the customer who is logged on.
Hope this helps.
Regards
Andre

How to use one PSE with multiple URLs?
I need to hit my DMZ SAP Web Dispatcher with multiple unique URLs. I am starting off using webdisp1.abc.com and webdisp2.vde.com. DNS will resolve both the Web Dispatcher Host. Following Tobias Winterhalter's Blog: Name-based virtual hosts and one SAP Web Dispatcher to access multiple SAP systems.
My question is how do I go about generating the pse so I can store both webdisp1.abc.com and webdisp2.vde.com? Do I just import the first request and initiate another certificate request using the same pse?
Example
sapgenpse gen_pse -s 2048 -p D:\<file path>\SAPSSLS.pse -r D:\<file path>\webdisp1.req CN=webdisp1.abc.com, OU=IT, O=XYZ Inc., C=US
Cheers,
Dan MeadHi Daniel,
what you are looking for are so called SAN certificates. As Martin said, with sapgenpse you are pretty out of luck. However you can create the certificates using openssl and then use sapgenpse to import them into a pse. There are a number of guides on how to create SAN certificates on the web, like the one mentioned by Martin from CAcert (which is one of the best imho) or this one. And there are also guides on the internet on how to convert OpenSSL keys to PSE.
You should however keep in mind, that SAN certificates are more expensive than standard certificates. Therefor they only pay if the hostnames in there are stable for the lifetime of the certificate. If the hostnames need to change once a year, you already will be better off (from a cost perspective) by creating one pse per hostname an let the webdispatcher listen to different addresses, as each hostname requires a new certificate signed by the CA.
Please also make sure, the systems and browsers connecting to your webservers are able to understand SAN certificates. For SAP systems this requires at least pl24 of the sapcryptolib.
Kind regards,

One application with Multiple schemas- common application frame work
Hi All,
I am trying setup a common application frame work in apex. Please help me.
How to achieve this.
Creation of one application attached to different schemas at run time. So that my application maintaince is going to be easy instated of creating copies of same application.
More details:
1. I have one application with 100 pages pointing to a schema dev_common in one workspace APP_COMMON. I have 50 schemas with same structure of dev_common schema with different set of data ( because of large amount of data).
So I want to create one application attached to different schemas.
2. And another thing is I have 100 users, the user can work on 1 or multiple schemas ( I mean same application with different schemas attached)
Any help much appreciated.
Thanks,Thank you for the reply.
>> b) I think you have to give access rights for the dev_common and app_common to all users.
Dev_common schema is a kind of placeholder. I have 50 schemas same as dev_common because of different business requirements but the front end is same for all 50 schemas. How can we create one application used for 50 schemas instead of creating 50 applications and 50 workspaces.
Please help me. -
How to have one provider with multiple portlets in JDev 11g
Hi,
I am trying to create Oracle PDK Portlets using JDeveloper 11g but for each portlet JDeveloper is creating a provider. As In JDeveloper 10.1.3.4 we can have one provider with multiple portlets in it. But JDev 11g creates provider for each portlet. How can we have one provider with multiple portlets in JDev 11g. Is it something changed in 11g version or am I doing it wrong. As the Help says we can have multiple portlets in one provider but when creating portlets it does not do that. Any help is appreciated.

How to use an Applet with multiple-jars
Hi everybody,
I would like to use an applet with multiple-jars.
ex:

How to develope application with multiple schema
Hi,
In my application, there is 3 schema, forms are from different schema, but the database is one. How should I manage it, When i open the form with different schema I am not getting the expected result,
I am using Oracle 10g Forms & Database
Thanks in advance
Rizlyhi,
what database-user is the user connected with, when executing the forms ? Is it one of the three schemaowners or has each logical user his own database-user?
About your db-objects:
I would create 3 roles, one for each schema, and grant the needed privileges for one schema to the according role
Example:
CREATE ROLE RL_SCHEMA1;
GRANT SELECT, INSERT, UPDATE, DELETE ON SCHEMA1.TABLE RO RL_SCHEMA1;
...Then you can grant the roles to the databaseuser you are connected with at runtime.
If you use named users (each logical user has it's own database-user) then you assign each user only those roles he needs. -
How to control one server with multiple clients via TCP/IP
I am wanting to control a single server with multiple clients. Only one client would be active at a time, so there would be no conflict. I want to use TCP/IP. So far, I have programmed a cluster that passes data back to the server with no problems. The challenge come in when a second client is added to the mix. I have't been able to figure out how to turn each client on and send the appropriate data and then turn it off so it doesn't keep sending the same data to the server.
Here are the things that I have considered and did some preliminary testing, but don't really know how to impliment:
1. Send a numeric on the front of the cluster packet that tells the server that data is on the way.
2. Send a boolean on the front of the cluster packet to somehow turn the server TCP/IP on.
The problem I have found is that LabVIEW TCP/IP doesn't like to be turned on and off. If it doesn't get the data it expects, it goes into a reset mode and that kills the response time.
Any help?You should consider implementing a set of simple one-byte commands that can be sent back and forth between the Server and the Clients. You can base all of these ideas off the example in the Example Finder under Networking >> TCP and UDP called Multiple Connections - Server.
You will have two loops in the server VI: one to wait for new connections, and one to send and receive data from the existing connections. For instance, after one of the clients connects, it can request control of the server to send data to it by sending the character "R" for request. Every time the send/receive loop of the Server executes, the first thing it can do is to check all the existing connections to see if any of the clients have sent a control request ("R"). If so, it will create a buffer (array) of control requests. This could be in the form of Connection IDs or indexes in the array for a particular Connection ID. Your choice.
After the Server receives a request for contol, if it is not already under control by another client, then it can send a response to the first client on the control request list. For instance, the server could send the first client a "S" command for send. Note that after the clients send their control request, they should execute a TCP Read and wait indefinitely for the server to respond with the one-byte "S" command. Then, once the client in control is finished sending data to the server, it could send the character "X" telling the Server to release it from control.
The example I mentioned above already does a similar thing. Note how when a client wants to disconnect, they send the letter "Q". You can see this in the Multiple Connections - Client VI. The Server then checks each individual connection to see if it's received this one-byte command, and if it has, it closes the connection to the client. This is what you would want to implement, but instead of having just one command, you'll have to distinguish between a few and build up a buffer of control requests.
Finally, if a client does decide to disconnect in your application, they could send the command "Q" just like the example above. At this point, close the connection and remove that Connection ID from the array of connections. You will also have to handle the case that this client was in the request control waiting line when it disconnected, in which case you need to delete it from that array as well.
This will definitely work for you, but it will take some work. Best of luck!

How to build a form with multiple tables in oracle application express
Hi everyone,
I have got problem in building a form with multiple tables.I have a main table with (20) columns and this main table is related to the other tables with the primary key-foreign key relation ship.My requirement is i have to build a form which has fields from many tables and all the fields are related to the main table using (ID) column.In that form if i enter ID field i have to get information from differnt tables.
Please help me to solve this (building a form with mutiple tables)
Thank you
sansSans,
I am no Apex expert, but with a situation as "complex" as yours, have you thought about creating a VIEW that joins these 7/8 tables, placing an INSTEAD OF trigger on that view to do all the business logic in the database, and base your application on the view?
This is the "thick-database" approach that has been gaining momentum of late. The idea is to put your business logic in the database wherever possible, and let the application (Form, Apex, J2EE, whatever) concentrate on UI issues, -
How to sync iTunes libraries on multiple machines without copying music
Background:
I have 4 machines running iTunes 9, all authorized with the same account. All music is on a networked storage device (NSA). Each iTunes points to the NSA for music files. Each user on each machine has their own local iTunes library for individualized playlists, etc. When music is purchased, regardless of machine, it is automatically downloaded onto the NSA. We have deselected the Advanced preference "Copy files to iTunes Media folder when adding to library". Our goal is to have one live copy of our music rather than multiple copies sprinkled about all 4 machines. We do periodic backups of the NSA.
Question:
How do I get all the iTunes user libraries on all 4 machines to automatically reflect new music purchases? The library of the purchaser is updated just fine, but no one else's is. The Home Sharing Settings option updates the library, but it also copies over the music, defeating the purpose of one copy.
Thanks in advance!When I first moved to OS X I decided that all of my/our music should be in one library, with one Apple ID for purchasing/playback and iPod syncing, located someplace other than each user's home folder. Using an alias of the destination folder worked as long as we were all on one machine.
Later when we acquired a second machine the setup was similar, except that the library was on an external HD attached to the newer/faster machine and accessed over our home network. The drawback of this method is that the machine with the library on it has to be up and running (of course).
We've finally moved further into the digital world by purchasing a network drive (NAS to be precise - a My Book World II for those who wish to know), upgraded our router and network switch to GB, and have a third iMac on its way (thank you eBay).
All of our music (the library we started years ago), all of our pictures, and other miscellaneous things reside on the NAS, which is also used for TimeMachine backups (on the non public volume). The idea being that any of us can access any of the media or documents as we need or want to.
Apparently (or I've missed something simple) Apple, in their wisdom, doesn't believe that a setup like ours (and apparently others as well) should exist. That each user and/or each machine, should have their/its very own music library that no one else can have FULL access to.
Home Sharing doesn't allow what I/we've been setting up from the first day we added music to our library. Sure it lets everyone with their own library to listen to other's library's that are up and running (i.e. the machine is on, and iTunes is running).
What we want to do is have all of our machines (the two, soon to be three, iMac's and one PC running XP) access the *same library* with full read/write/burn access AT THE SAME TIME! Hence the logic in purchasing a NAS. What we can't do is have iTunes running on more than ONE machine at a time since the other network users/machines receive this message:
The iTunes Library file is locked, on a locked disk, or you do not have write permission for this file.
Which is certainly not the case since each user/machine can access, read, write, and burn from the above library at will as long as they are the only person doing so.
Changing the permissions on the library file doesn't stick (probably because its on the NAS), otherwise I would have done that and you wouldn't be reading this.
Thanks for any help anyone can give. -
How can use full app with multiple monitor

How to use one iPad on multiple computers on different networks using one AppleID
Hi everybody.
I'm living in two places, 250 km distant, both equiped with PCs, one running Windows 7 and the other Windows XP. They run last version of iTunes ans I use the same Apple Id.
As one is the backup of the other, both have all the videos I'd like to broadcast on may iPad (not enough place, so no download). Some of them are TV shows I bought from iTunes, other one are personnal videos.
All was perfect on the first PC (the one running Windows 7) until I activate the same setups on the second one. Now all is fine on that PC, but home sharing on the first one doesn't work anymore. When I open Videos (the application) on iPad, the only thing I see on the menu is "TV show", wich allow me to download the TV shows I bought. I guess they are donwloaded from Internet, not from the computer running iTunes on the local network. And I don't see anymore the "shared" menu I saw before that allow me to broascast personnal videos.
The Apple support say that what I'd like to do is not supported yet, but I'm not shure they really understand my configuration.
Does anybody use successfully the same configuration, or did someone encounter the same problem ?
Thank'sI do not understand the qestion. When you get a CC subscription you get it for specific software... or you can get a plan that covers multiple applications.

How to use one query against multiple table and recieve one report?
I have duplicate tables, (except for their names of course) with commodities prices. They have the same column headings, but the data is different of course. I have a query that gives me a certain piece of information I am looking for but now I need to run this query against every table. I will do this every day as well, to see if the buying criteria is met. There are alot of tables though (256). Is there a way to say run query in all tables and return the results in one place? Thanks for your help.
hey
a. the all 256 tables whuld be one big partitoned table
b. you can use all_tables in order to write a select that will write the report for you:
SQL> set head off
SQL> select 'select * from (' from dual
2 union all
3 select 'select count(*) from ' || table_name || ' union all ' from a
4 where table_name like 'DB%' AND ROWNUM <= 3
5 union all
6 select ')' from dual;
select * from (
select count(*) from DBMS_LOCK_ALLOCATED union all
select count(*) from DBMS_ALERT_INFO union all
select count(*) from DBMS_UPG_LOG$ union all
remove the last 'union all', and tun the generated quary -
SQL> set head on
SQL> select * from (
2 select count(*) from DBMS_LOCK_ALLOCATED union all
3 select count(*) from DBMS_ALERT_INFO union all
4 select count(*) from DBMS_UPG_LOG$

Using one iPad with multiple iTunes accounts
I am trying to understand the iTunes implementation on iPad..After synching my MBP on an iPad, all of my settings music, photos,mail are transferred to the iPad...my wife now wants to use the iPad as we are traveling...can my iPad's iTunes be signed off and her iTunes account be logged on thus she can access all her data stored on her iTunes account? I have spent a lot of time investigating this on the forum and I do not understand what can and not can be done...If this can not be done, then if any iBooks we want read (different books for me/wife) then needs to be purchased and read on the one iPad needs to be bought on only MY account which is synched to my MBP... ? It seems that you need one iPad for each user...(we each have our own MBP)?
The iPad is not set up to allow different users with different data.
All users have the same data.
iTunes account = iTunes store account to make purchases
iTunes library = everything in iTunes when she logs in with her computer login
wife now wants to use the iPad as we are traveling...can my iPad's iTunes be signed off and her iTunes account be logged on thus she can access all her data stored on her iTunes account?
If you mean she want to sync the ipad with her iTunes library, yes.
She will need to login to her computer account, connect the iPad, launch iTunes then sync it.
This will erase all your data on the iPad and sync all her data.
If you mean can she access iTunes store account, launch iTunes on the iPad, scroll to the bottom and tap Sign out iTunes then sign back in with her iTunes account.
This will not add anything of hers to the iPad but she can make purchases with her iTunes account. -
How to use one monitor with two Power Macs
I searched this forum and was unable to find an answer. Although I believe it's probably here.
Nevertheless, I have a Power Mac G5 and a rarely used Power Mac G3. I'd like to share the G5's VGA Accusync 120 CRT monitor with the G3. I know there is a way to switch the monitor between computers without pulling plugs in and out of the machines.
Does anyone have any specific switch I could buy to solve this issue. I don't care so much for picture quality for the G3. But I don't want to compromise picture quality for the G5.You're looking for what's called a KVM (Keyboard, Video, Mouse) switch.
This one should do what you're looking for. I've not used it, but it does VGA switching like you want and is inexpensive. -
