State management of package PL/SQL in ADF
Hi allI redesign a form of Oracle in the ADF. The shape is a front end for some fairly complex processing that is provided by a database package. The package maintains the different data elements in its State which are used during the session of the interactive user. I would like if possible to reuse functionality in this package for the ADF in the screen version. Clearly, in order to use the package as what I would need to ensure the that maintaining the connection to the database for the user's session just as it would be in forms.
I have been reading up on top of the connection and the Application Module pool and think it is possible to switch off the two pools and ensure that a user session gets a single database session - set jbo.ampool.doampooling = false and jbo.doconnectionpooling = false (default). I am not mistaken in this or have I missed part of the battery of the session/connection?
Assuming that it is possible, is it advisable? The maximum number of concurrent users on the application server would be about 200, access to a number of different databases.
The alternative I suppose would be to redesign the package in the ADF BC layer. While it is perhaps the best architecture if there would be a major effort in the redevelopment of the Java code from scratch.
I use JDeveloper/ADF 11.1.1.3.
Thank you very much
Kevin.
Yep, it's no doubt that the technique is called 'Dynamic JDBC Credentials'.
In this for terms is it advisable, for 200 users, assuming that the memory of your package is not huge each user would be nice. Ideally you don't want to rewrite (and a new test) all this code database then go with what you have.
However, in saying that this is not the best option when you want to scale to a huge amount of users. The best way to make sure is to stress test by using a tool such as JMeter to see if things stand up to.

ORA-04068: current state of the packages was waived - avoid
Hello
I fight with the bad behavior of developers that is, something like this:
I did some tests and looks like when you recompile pkg1 withCREATE OR REPLACE PACKAGE pkg1 IS g_version VARCHAR2(20) := '7.3'; TYPE t_id_kon IS RECORD( id_kon VARCHAR2(12), sr_id NUMBER(5)); TYPE t_id_kont IS TABLE OF t_id_kon INDEX BY BINARY_INTEGER; FUNCTION get_version RETURN VARCHAR2; END pkg1; /
Global g_version variable it is ORA-04068 generated for all sessions using this pkg1 before recompiling.
But what about type and table_type declared in pkg1 they cause same behavior as g_version global varialbe?
And generally how to treat than the types of situations of application point of view, you must catch this exception and re-run your application just?

GregGPackages tend to fail because of their 'package '. A package has a 'State' when it contains the package variable and constant level etc. and the package is called. On the first calling package, the 'State' is created in memory to hold the values of these variables, etc. If an object including the package depends on for example a table is changed somehow example deleted and recreated due to data dependencies, the package then takes a State not VALID. When you do then appealed to the package, Oracle examines the status and see that it is not valid, then determines that the package has a "State". Because something changed the package depended on, the State is taken as being obsolete and is ignored, which causes the error "State package has been abandoned" message.
If a package has no variables of level package etc. i.e. the 'State' and then, taking the same example above, the whole takes an INVALID state, but when you make then a call to the package, Oracle considers as invalid, but knows that there is no 'State' attached to it and is therefore able to recompile the package automatically and then continue execution without causing error messages. The only exception here is if the thing that the package was dependent on a change of such kind that the package may not compile, in which case you will get an invalid error package type.
And if you want to know how we prevent Jetty package States...
Move all variables and constants in a stand-alone package specification and to refer to those of your original package. So when the status of your original packing is invlidated for some reason, it has no State package and can be recompiled automatically, however the packaging containing the vars/const is not cancelled because it has no dependencies, so the State that is in memory for this package will remain and may continue to be used.
As for package-level sliders, you will need to make these premises to the procedures/functions using them as you won't be able of sliders reference in all of packages like that (not sure on the use of the REF CURSOR but... exists for me to study!)
This first example shows the State being disabled by adding a new column on the table and causing to give a 'Package State scrapped' error...

error ORA-4068:-l' current state of the package is invalidated
Hai friends,
Please see this link
Problem we faced, it is ' error ora-4068:-l' current state of the package is disabled "in the application.initiallly of customer, we migrated to oracle 9i and 10g 10.2.0.4.0
We have discussed and obtained the solution as the timestamp of the objects may be different. (we expect the access rights of the table sys.obj$) pls see the link
But now we are informed senior as below
(1) error ora-4068 will come only when recompile us the view. is this true?
(2) 6136074 bug is fixed in 10.2.0.4.0. is it?

Problem to generate Java package PL SQL in Jdeveloper
Hello
I have problem to create the java class package PL SQL in JDeveloper.
I use jdeveloper database navigator and right-click on a package and choose generate Java then in the Jpublisher window choose my controller view and accept other default values.
I call methods in the generated class in the Action of a button in my JSP page, but when I click the button it throws null pointer exception! I Fund one of the generated method return null and it lead to this exception.
protected DefaultContext __tx = null;
public DefaultContext getConnectionContext() throws SQLException {}
If (__tx == null) {}
__tx = (getConnection () == null)? DefaultContext.getDefaultContext (): new DefaultContext (getConnection ());
}
Return __tx;
};
public connection getConnection() throws SQLException
{
If (__onn! = null) return __onn;
ElseIf (__tx! = null) return __tx.getConnection ();
ElseIf (__dataSource! = null) __onn = __dataSource.getConnection ();
Return __onn;
}
I'm trying to generate the class in the model project and create DataControl to it and use the action method, but noting the change and I get null pointer again!
JDeveloper Versino = 11.1.1.7.0
I would like to ask you another question: why generate java packaging at all?
Where you want to call the package?
Back to your question: you should see the code as
Public Sub setDataSourceLocation (String dataSourceLocation) throws SQLException {}
javax.sql.DataSource dataSource;
try {}
Class cls = Class.forName ("javax.naming.InitialContext");
Object ctx = cls.newInstance ();
Meth java.lang.reflect.Method is CL. GetMethod ("search", new class [] {String.class});
dataSource = (javax.sql.DataSource) meth.invoke (ctx, new Object() {"java: comp/env /" + dataSourceLocation});
setDataSource (dataSource);
} catch (Exception e) {}
again throw java.sql.SQLException ("data source initialization error in" + dataSourceLocation + ":" + e.getMessage ());
}
}
in the generated code. This code search a data source (that you have defined for example on the Weblogic Server) by calling the method
setDataSourceLocaltion("jdbc/HRConnDS");
That look to the top of the n data source stores in the class variable.

I get the following error only for the '"first run" ", even the package is in State"valid ". If the execute the same package to new "second run", it works ok.
usually we complie all 'invalid objects"in the diagram, when we pass the TEST or PRE-PRODUCTION code approx.
but I get the following error, even if the package is in State "valid".
I went through the next thread, blu explained the cause of this error,ERROR at line 1: ORA-04068: existing state of packages has been discarded ORA-04061: existing state of package "TEST_OWNER.TEST_PKG" has been invalidated ORA-04065: not executed, altered or dropped package "TEST_OWNER.TEST_PKG" ORA-06508: PL/SQL: could not find program unit being called: "TEST_OWNER.TEST_PKG" ORA-06512: at line 2
but we receive this error even when the package is 'valid' State too?
Which session refers to a package for first time package is instantiated in memory of the session. If the package is recompiled, Oracle assumes he may have changed and the package in memory session instance is no longer valid. This is why any reference to this package made by this session will raise an error.

Running a package in SQL Developer
Hello
When I introduce a new package in a database and the package is given bz *.pkg file, what is the difference between the opening of the packing of files in SQL Developer (via 'Open '->' file') and then run the package and just copy paste the code Pl/SQL package in an editor.
I plead the cause I did the following experiment, which I've posted it here:
Faraz' Oracle DBA Blog: error opening a PL/SQL package as a file in Oracle SQL Developer
Run the file that has your ddl inside package and execution of the package itself - two different things.
When you open a file in SQL Developer, according to the file extension, you will get either a SQL worksheet or a PL/SQL Editor.
I'm assuming that your package file has made two database objects, the package specification and package body. If this is the scenario, you need to open it in a SQL worksheet, set your connection details, and then run with F5.
If your file contains only a spec or body in pkg, you can and should open in the procedure Editor. There, you will see your highlight syntax errors in the code itself.
I speak a little of that here, with some screenshots so I hope it's easier to understand.

Hi all
How we can find the bottoleneks in the pl/sql package. I know we can use dbms_profiler. Gathersed data, but not having planned the details.

SELECT statement in a Package body
I have the following in my package body and it gives me an error:
- Error (7.1): PLS-00428: an INTO clause in this SELECT statement
PROCEDURE MyQuery
AS
BEGIN
Select * from customer;
END MyQuery;
The error message is correct.
Your selection must have an INTO clause and must return 1 and only 1 row.

Create the PL/SQL package in SQL Developer 4.0.0.12
Hello
I built a model in SQL Developer 4.0.0.12 and I want to create a PL/SQL package.
In ODMiner 11.1.0.4 of 'Tools' > 'Create pl/sql package' I can get a script to create the package and every thing is OK.
but in SQL Developer, I select "Deploy" from the popup menu of each node and it generates a folder containing scripts associated with each node. I don't see any relevant script for creating a package.
How can I create a PL/SQL package in my workflow?
Thanks for any help you can provide in this situation.
Please see this whitepaper to find out how to build the PL/SQL package for deployment of workflow:

INSERT statement is slower in PL/SQL, SQL
I can't understand why an insert in PL/SQL is much slower than in SQL (against 5 minutes 2 seconds).
INSERT statement and explain plans are below.
The BIG difference is that I use an immediate execution with bind variable because I'm passing in the dynamic table/column names. Maybe that confuses the optimizer? Another point is that if I remove the 2 'GOLD' terms these two queries run the same speed.

status of the database api (PL/SQL) based adf BC?
Hello
does anyone know the status of the API database (PL/SQL) based project ADF BC?
(mentioned here: https://groups.google.com/forum/?fromgroups#! msg/adf-methodology/TiP2JXQm_Ag/zNbD7Kyf6hUJ)
The following link does not work:
https://database-API-based-ADF-BC.SampleCode.Oracle.com/
It is also not included in the sample code oracle: http://www.oracle.com/technetwork/indexes/samplecode/jdeveloper-adf-sample-522118.html
concerning
PeterHello
The following link does not work:
https://database-API-based-ADF-BC.SampleCode.Oracle.com/Avrom and EMG moved the project to a server that no longer exists. I had the code example of Avrom (at least a copy) and intend to work with Chris Muir to again make it a project of the EMG. Due to my time constraints used to be until the end of the year.
The code that you can download on the blog of Avrom however works fine.

The user managed backup hot via Sql
Hi being a little old school - I'm trying to understand the steps required for a Hotbackup managed through Sql (sorry fans RMAN!)
I understand that I can save each tablespace in turn (via the necessary ALTER TABLESPACE < x > BEGIN BACKUP and then out of backup)
I also assume that I simply take a backup of my control file (wither in binary form or trace if necessary)
I also assume that you do not back up the Redo Logs (since you reset draw on any recovery anyway)
The bit I'm not sure of is the Undo Tablespace - can be backup in eactly the same way as any other tablespaces?
Y at - it all components that I need backup (outside the archive logs)
Thank you
JimAlways provide the Oracle version 4-digit.
The documentation covers all of the steps required for a manual backup.
http://docs.Oracle.com/CD/B28359_01/backup.111/b28270/osbackup.htm#CEGJIHJF
See Chapter 27 Making User-Managed database backup for instructions.
