Deploy form, question about database object or connection parameters

When form to be deployed to the dev/test/production environment, should it be compiled with that specific database connection username, password and sid? Another words, when I compile the database objects created for the compile is embedded in the .fmx file?
thanks for help

You won't need to compile your forms if the passwords of the target schema differs. It also doesn't matter on what platform/architecture the database server runs on. However it would matter how you created your schema objects. And of course it will matter if the platform your forms run on differ. The list of "what you need to do when you don't want to compile against the target database" is a long one.
Here is a short list of don'ts
- no +select * from [...]+ views
- no +select * from [...]+ in forms cursors and the like
- %TYPE is evil
- %ROWTYPE is much more evil
Those are just a few obvious things developers can mess up. Of course we all know that this sort of things are bad programming practice but they do happen. And as said: that's just the most obvious things. I work for a vendor where only the compiled files are shipped to the customer, and the road to this goal is a hard and bumpy one. If you don't want bad surprises in production I suggest you implement a fixed build process routine and a fixed upgrade process where you can ensure that the target database where the forms run against match exactly the development database you compile your forms from a logical point of view. The far easier exit is to just compile your forms on the target platform against the target database but I understand that this is not always possible.

Few basic questions about database administration

Hello,
I have a few basic questions about database administration.
1. I switched one of my oracle instances to archivelog mode. I just cannot locate the archive log files on my windows system. The %ora_home%/ora92/database/archive directory is desperately empty...
2.What is the tools01.dbf datafile used for?
3.What is the undotbso1.dbf datafile used for?
Thanks in advance,
Julien.

1. The archive log location needs to be specified in your init.ora file. By default, Oracle will place the archive files in either ORACLE_HOME/dbs or ORACLE_HOME/database.
2. The tools01.dbf file belongs to the tools tablespace which should be set as the default tablespace for system. It primary purpose is to hold Oracle Forms and Reports database objects, however, it should also be used for holding other non sys database objects such as the perfstat (statspack) or other third party database schemas e.g. quests sqllab.
3. undotbs01.dbf file belongs to the undo tablespace.

Question about Database Access

Hello,
I have one question regarding database access from Java.
What are the other ways of connecting to database other than JDBC? This was one of the question I been asked by the interviewer. He says JDBC connection can slow down the perfomance when it comes large number of transactions?
Any insight or help will be very useful.
Thanks

He may have been referring to available "persistance managers" like Hibernate or the mechanisms build into EJB containers. However, as far as I know, they all use JDBC, and any speed-up is due to caching of data as objects.

Questions about Audigy 2 ZS connecti

Hello,
New to these forums, so bear with me. I'm considering purchasing an Audigy 2 ZS gamer card, and have some questions about the card and speaker setup. I've read the FAQ's in the forum, and they have been a big help, but I still have questions related specifically to my setup. Here's the system specs:
AMD Athlon 64 3000+
Asus K8V SE Deluxe
VisionTek Radeon X800 XT PE
Seagate 250 gig SATA HDD
gig Crucial ram
Antec P80 case
Antec TruePower 430 ps
Altec Lansing ADA885 digital speakers (awesome sound)
Altec Lansing headset (cheap but works for voice and gaming)
ADI AD980 onboard sound
Windows XP Home
. I currently am able to run both the speakers and headset at the same time by using the front panel audio outlets on the case (helps with the immersion in IL2 946). I would like to continue doing this(using front panel audio) with the new card. I've found several places that have an adapter cable for sale, http://www.x-tap.com/
http://www.performance-pcs.com/catal...oducts_id=2700
http://ask.americas.creative.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=ww_english_add,U={B8F6030-DA4F-D3-94F4-00500463020E},Company={CEAE26D-879-4C00-AC9F-03BC258F7B70},d=3025443648,VARSET=ws:http://us.creative.com,case=5764
The plug that I have has only 3 separators, not 4. Will this work with the Audigy 2? I don't have a link for this plug, unfortunately.
4. I had been considering purchasing? a set of USB headphones, but I've been told that when you plug them in, the sound is cut off for the speakers. If there was a workaround for this, I might consider getting them. Then I wouldn't have to use the front panel audio or the connections on the card.
5. I've heard of an issue with this particular set of speakers and the Audigy 2 card, particularly that the speakers were originally designed for a Dell system, and the wiring was phased differently than in other systems. Is this something to be concerned with, and if so, is there a workaround?
I like to research a particular product before I buy it, in order to make an informed decision and avoid problems if possible. Sometimes it works, sometimes it don't
Thanks in advance for the help.

The inputs are easy to find and select:?
Right-click the Mixer icon on the taskbar and select "Playback Devices".<
There should open a new Window with the options of "Speakers" and "SPDIF"<
With Speakers highlighted click the?"Properties" button on the lower?right corner<
Go to the 4th tab (I believe it is "volume" in english, "Pegel" in german)<
There you have your inputs!<
Unmute Line-In and set its volume according to your desires.<
Also remember that software designed for XP, that should control the Line-IN settings, (ie. Hauppauge WinTV or Dscaler) will be unable to do so in Vista, do to the architecture change. You can however enable "Compatibility Mode for Windows XP SP2" for these applications (right-click on their executable) and restore control of the inputs directly from the program. (You should however unmute it first as explained above). PS:? All Creative Software that came on the CD is incompatible to Vista. Only the included Audio Console should work as expected.Message Edited by alexs3d2 on 05-07-200707:3 PM

Question about java objects and handles?

Let me see if I can explain what I have. Inside my originating Java code, I create an object, let's call it object A, from a class I that I DON'T have the source for. It's not my class. Object A in turn creates an object, let's call it Object B, from a class I don't have the source for. Then Object A creates another object, let's call it Object C, that I DO have the source for, and passes it the reference to Object B that it created. My question is this: In my originating Java code, how do I get a reference to Object B? Or, how can I get the reference to Object C, which would allow me to get the reference to Object B?
Hope everyone understands that?

Thanks for the reply. Perhaps I should have mentioned that Object A does not have a method to return a referenece to Objects B and C. That's my problem. Was just wondering if there is some other way to obtain those refereneces. The reason I mentioned that I don't have the source code for Object A is because if I did, I could obviously write a method that would return me the references.
I'm not new to Java, nor am I an expert either. I'm pretty well up-to-speed on object oriented design though.
I'll provide more specifics on my problem just in case there is a solution to my problem. My code (class) is attempting to establish a connection with a mainframe computer through a web server portal using terminal emulation software provided by a 3rd party vendor. They provide an SDK that contains all the java classes necessary to establsih the connection. To establish the connection, you are required to build a java Properties object that contains all the parameters for the connection (host id, etc.) and pass that properties object to the constructor for the "Object A" class. That object actually establishes the session object using the parameters object you pass it. The session gets displayed in a standalone Applet ("Object A" class extends Applet). You can click on the applet, sign in to the system, and do whatever just fine using your keyboard. However, I wish to send commands to the session from my originating java code. The session object has a method to send commands to the session, but to do that, I need a handle to the session object that was created. I don't have that, and it appears they don't provide a method to get that. Looks like the vendor's intent was just for the user to interface with the session/Applet via the keyboard.

Question about Proces Object

Hi
I am running a shell script through a Java program using Runtime.getRuntime().exec() after certain intervals.
I am passing certain parameters to the shell script.
My first question is that can we pass parameters to the shell script. I believe it can be done because all we have to do is pass a String as an argument to Runtime.getRuntime().exec().
I also want to ensure that if the shell script is currently executing I wait for the shell script to end before invoking, basically checking of the process is currently running or not. If someone can paste some code snippets it would be of great help.
Thanks in advance.

dev_nilesh wrote:
My first question is that can we pass parameters to the shell script. Yes. Sometimes it will work just by passing the whole thing in a single arg: exec("ls -ltr") but a more general approach is to use one of the signatures that takes an array: exec(new String[] {"ls", "-ltr"}). You might also want to look at the ProcessBuilder class, which was introduced in 1.5.
I also want to ensure that if the shell script is currently executing I wait for the shell script to end before invoking, basically checking of the process is currently running or not. If you mean that after you start the process, you want your Java program (that thread of it anyway) to pause untill the process completes, use Process' waitFor() method.
If you mean that you want to make sure nothing else is executing that script before you Java program invokes it, there's no good general way to do that in Java. You could first exec a ps command, or your OS's equivalent, and look for that process, but that's fragile, and the process could start between your ps and starting the script. A better approach would be to have the script itself make sure it's only run once at a time. The usual approach for that is to have it open a socket on a fixed port at startup.

Question about database objetcs in forms 6i

I have to make the roles for a database so i need to know what objects in the database use a form, there is a program to do that ???

This may help.

Question about creating objects in Forms 6i

Hi,
I'm trying to create by code dynamic items in a form, but I don't find the way to do it, or any tutorial in the internet.
Taking a look at the Forms Help it says 'Once you create a data or control block, you can create items in that block at any time. Create items via the Object Navigator by inserting them under the desired block, or via the Layout Editor by drawing them on the desired canvas.'
Is there a way to create items and assign them to datablocks by code? something like CREATE_ITEM?
All I want is a button that inserts textboxes in a canvas, as many items as you want.
Thank you in advance

Hello,
There is no Create_item() built-in to create item at runtime.
You can create hiden item at design time then show them at runtime.
Or you can use some java code to create component at runtime.

A question about database schema when creating JClient Form

Sir,
I created a JClient Form application using the wizard, in which a JCLoginDialog was generated. Then I modified the JCLoginDialog.java file so that it works with JDBC instead of with the OracleAS JAAS Provider. My name is the database schama name, and I created the form using my name.
When I log in using my name, It is fine. But when my colleague log in using her name, it is failed. The error message said that the table is not found. My colleague has access of the related database table through a database role.
I think it is the schema problem when I create the model project. I do not know how to add the schema name before the table name, such as stephen.mytable .
Please help me. Thanks
Stephen

I have solve the problem. That was a mistake I made.

Question about Databases on a distributed environment...

Hi,
I have quick question. We have production in a distributed environment as follows
(a) SQL server, EPMA, and Calc Manager
(b) Workspace, and Shared Services
(c) Essbase
(d) Planning
Now we have multiple databases for each hyperion service i.e.
(1) HSS (using for hyperion shared service)
(2) BIPLUS (Using for workspace)
(3) AAS (Using for Essbase Administrator Services)
(4) CALCMGR (Using for calculation manager)
(5) EPMA (Using for EPMA)
(6) ERPI (Using for ERP Integrator)
(7) PLANSYS (Using for Planning)
Now, my question is ....is it necessary that we have that multiple database in a distributed environment or we can have one database for everything? What is main objective for creating databases for each application?
Please share your best knowledge and give me positive and negative about multiple database and single database for hyperion...
Thanks to all...
Safi

I am going to be lazy and copy an extract from the install doc
For simplicity and ease of deployment, you can use one database repository for all products (with the exceptions noted below). When you configure multiple products at one time using EPM System Configurator, one database is configured for all selected products.
Caution!
To use a different database for each product, perform the “Configure Database” task separately for each product. In some cases you might want to configure separate databases for products. Consider performance, rollback procedures for a single application or product, and disaster recovery plans.
The following products and product components require unique databases:
Performance Management Architect interface data source
Extended Analytics for Financial Management and Extended Analytics for Strategic Finance
Planning – Each Planning application should have its own repository.
Performance Scorecard
FDM – Use an Oracle Database instance exclusively for FDM.
Data Relationship Management.

Question about using objects in SQL query.

I had posted this question in the SQL/PLSQL forum but I guess nobody took the time to understand exactly what I am asking so I decided to try here hoping to get the answer. So here is the thing:
I have created generic object type "tree" - the constructor takes as a parameter sql query which returns "node_id" and "parent_node_id" - this is all we need to have a tree. The object has all related to a tree structure member functions and one of them is "oldest_relative" (the tree may not be fully connected - it may be more like a set of many trees, so it's not necessary all nodes to have the same root).
I also have departments table with the following fields: department_id, parent_department_id, department_name,...
all records in the table w/out parent_departments (parent_department_id is null) are considered divisions.
Now if I run the following query:
SELECT "DEPARTMENT_ID", "PARENT_DEPARTMENT_ID", "DEPARTMENT_NAME", tree('select department_id "node_id", parent_department_id "parent_node_id" from departments').oldest_relative("DEPARTMENT_ID") "DIVISION_ID" FROM departments
my question is: Is the tree object created for every row or does Oracle somehow caches the object since the object itself is not changing but only the parameter for the oldest_relative member function.
The table only has a few hunderd records and I can't see much of a difference in the execution time btw the query above and query like this:
SELECT "DEPARTMENT_ID", "PARENT_DEPARTMENT_ID", "DEPARTMENT_NAME", b.t.oldest_relative("DEPARTMENT_ID") "DIVISION_ID"
FROM departments left join (select tree('select department_id "node_id", parent_department_id "parent_node_id" from departments') t from dual) b on 1 = 1
where the object is clearly created just ones. (there is probably a better way to do it instead of this join)
Pls elaborate
George

Not exactly sure what the question is...
As I understand, you are comparing the following two constructor calls:
+select.. tree('select department_id "node_id", parent_department_id "parent_node_id" from departments').oldest_relative("DEPARTMENT_ID") ... FROM ...+
+select tree('select department_id "node_id", parent_department_id "parent_node_id" from departments') ... FROM dual+
These calls are the same (besides the 1st one doing an immediate implicit call to a method of the object being constructed). The number of times these are being called depends on the number of times this SQL projection is applied - and that is determined by the number of rows being projected by the SELECT.
The latter one is against DUAL which only has a single row. So that constructor is only called once. The former can be against multiple rows. Obviously a single pass through a data set is desirable - which means that the sub-select (use by the constructor) should ideally only be executed once and makes the 2nd method more desirable.
However, I'm having a hard time understanding why the class and constructor are at all needed. Why pull data from a SQL table into PL memory? As that is where the class will need to cache and store the results of that construction parameter SQL SELECT. And once in PL memory, how does the object effectively access, search and use this cached data?
PL memory is expensive. It is not sharable.
PL data structures are primitive - these cannot be compared to SQL structures in the form of tables and columns that can be stored in a number of physical ways (index tables, hash tables, partitioned tables, clustered tables, etc). Cannot be indexed like SQL structures using B+tree, bitmap, function and other indexing methods. Cannot be sorted, grouped, analysed, filtered, etc like SQL structured data.
It makes very little sense to read SQL data into a class and then deal with that data, cached in expensive PL memory, using primitive PL structures.
And the same would be true if Java or C# was used. The best place for data is inside the SQL engine. That is the most superior environment for data. It can processes more data, scale better, perform better and offer more flexibility, than pulling data from it and then crunch that data using PL or Java or C#.

Questions about database application tables connector

Hi all,
I need to manage with OIM several databases (each one with its custom tables).
Also, one of them will be my trusted target on the initial load of users. The structure of our tables is not similar to the included in the example.
The documentation explains how the OraAppX.xml could be modified but it doesn't speak about relations with "DBTable_nonTrusted.xml" and/or "DBTable_trusted.xml" For example, if I don't have a column called USR_COMM_LANG, could I replace this column name for another that I have in my database ? And what about the references on the "DBTable_nonTrusted.xml" file. Connector doc doesn't explain how references to that field (USR_COMM_LANG---xel_usr_comm_lang) are managed by the connector and if the normal working of the connector could be affected if the name of a variable is changed in the xml conf file.
It could be that adapters of this connector were hardcoded with the referece to xel_usr_comm_lang (???) .
The connector documentation includes a section titled "Adding Custom Database Columns for Provisioning and Reconciliation". The first impression reading this document is that it is possible to extend the predefined table rather than create and define a new structure of table.
Has anyone rebuilt the "DBTable_nonTrusted.xml", "DBTable_trusted.xml" and "OraAppX.xml" files changing all default variables in order to manage a customized table? .
Many thanks in advance,
Claudia

Hi Claudia,
1) Yes, you must replace the column names in the "column" tag on your XML file for the column names that you have in your database tables. Also, remember that you need to configure the other parameters (like data_type, data_typ_size, etc) according to your database table.
2) The "xel_data_source" parameter is the attribute name that will be recognized by the OIM and they can be mapped to a form field (UD_DBAPP_XXXX) in your process definition in OIM Design Console.
3) You can customize your Database Application Tables connector for provisioning as you wish, but some issues exists. In the Known Issues section of the documentation you can see that this connector doesn't work for more than two tables.
4) To customize your Database Application Tables for Trusted Recon, there are other restrictions because OIM users have some required fields that must be filled to create a user successfully.
Hope that helps, and please let me know if you have more questions.
Regards.

Questions about database pooling....

Hi everyone, I'm not new to java programming but I am looking to polish up my skills. I have read sooo many articles and am still confused so please be patient with me. Java has a way of adding new acronyms everytime I turn around - its very hard to keep up with...
I am using Netbeans 5 with Tomcat 5.5.9 bundled.
I am connecting to a postgresql database (version 8.1).
I would like to implement some type of jdbc connection pooling. Everything I have read, even on the tomcat website is confusing and seems to be a "best effort" type of situation - none gauranteeing correctness or reliability or replicability between what others may experience and what I might.
I looked into a pure java solution such as DbConnectionBroker but I get confused as to how this "pooling" is effected by servlet lifecycles. I have read and read and still do not understand the necessary concepts.
If I have a login servlet that makes a single query to the database, how long does that instance of the servlet stay loaded into memory? If it is dropped out of memory right away it seems there is no benefit of using the connectionBroker? (since each time someone visits the login servlet it would have to recreate the login servlet and broker object??)
Is the broker object kept in memory somewhere with connections open after the servlet stops executing? How can other servlets access that same broker object without creating a new one of their own??
I guess it comes down to really not understanding the persistence of how things are loaded and kept in memory. If this is a question for the Tomcat people I do apologize :/ It just seems these forums are by far and away the best place for any type of java help :)

A servlet has nothing to do with it.
A servlet uses a pooled instance. It is the pooled instance, not the servlet which is cached. At least in terms of discussing db connection pools.
A cache means that it remains in memory. If the cache isn't kept in memory then keeping a cache is pointless.
I guess it comes down to really not understanding
the persistence of how things are loaded and kept in memory.More of a basic java question than anything else.
The GC will collect reference which are no longer active sometime after they become not active. Thus a local reference can be collected after the method exits. But a static will not be collected until the class is (not instances of the class, but the class itself.) That won't happen until the class loader that loaded the class is collected.

Questions about Database roles

Hi,
Need to setup a new (Windows) user which has varied access to tables, views and procedures in about 8 different schemas all in the same database.
I've created a instance level login and then gone to the database to set the more granular details.
First question. Does this user need to own the schemas they will access?
Secondly, I'm assumign the best bet would be to create a database role and then apply the privs against that?
I need to give access to all stored procedures (and future procedures) in a couple of these schemas and none in the others. Is it possible to grant execute on all procedures in a schema whist prohibiting others?
Then I would assign the database role to the new instance login?
Thanks

In the database he has access to a number of schemas but I wish to explicitly exclude him from all views in those schemas and in addition to this all the sys catalogs, e.g
Also have no idea how to restrict access to the user created views without doing them all manually, but then what happens in the future if new views are added? They are not going to be explicitly denied.
David nailed the problem.
There is no way to differentiate SELECT permission between Tables and Views. If they are all in the same schema and tables are allowed and views not.. out of luck and have to include the allowed object one by one (as opposed to denying the not allowed ones
with the risk of missing some in the future)
This is why database design should have security in mind from the very beginning and views, being a way to access (aka "access-schema") data in tables should ideally be placed in a separate schemas
