Question about global context.

Hi.
I have this scenario:
1) Context set within the application:
a) user logins and identifies basic context info: company id, etc.
b) Context is set in a package
b) Views are the underlying datasource for application and they are created using context info. For example:
Create view some_view as
select * from some_table where company_id =sys_context('access_control_ctx','company_id')
2) This works perfectly in a dedicated / persistent connection. However if ones tries to use connection pooling, like in a Web app, say Apex , this won't work as expected.
3) An alternative is to use global context. However i have this question:
(a) User a logs in to application and set values for company 1.
(b) User b logs in to application and set values for company 2.
How does global context works in this situation?. I mean, since every user needs a different value form company_id? How can one guaranties they both will point to their respective value without having to change the application security / access control?.
Regards, Luis ...!

Specific to APEX, you can use the v function to access APEX session state information (i.e. v('APP_USER') to get the currently logged in application user).
If you are going to use a global context, you would need a session ID (or something similar) that is stored as a part of the global context to determine which session you are interested in. The global context would have A's data with A's session ID and B's data with B's session ID and before you get the context information, you would need to specify which session ID you are asking about.
Tom Kyte has an example of using a global context

Question about the Context

Hi:
I'm a freshman with the EJB.I'm ambiguous of the Context in the EJB.What's the Context?How to use the EJB?
Please tell Where can I find the document about the Context,thank you.

Hi Wjun555
The context provides information about an EJB. So for example, the InitialContext used to lookup an ejb provides the information required to connect and obtain a remote reference (or a local reference) to an EJB.
The EntityContext and SessionContext provide information about the EJB while it is running. This includes information such as what user invoked it, whether its running in a transaction, what kind of transaction, etc.
Thanks,
Brian

Basic PL/SQL Question about running context

We are trying to create some generalized tools with PL/SQL procedures that would be used by a number of different Oracle Users/Schema. The idea was to store them in an administrative schema (call it ADMIN), create public synonyms for them, and grant execute to public. Then we could run them from the user schema (call it USER) to do the work.
It was my assumption, that while the procedures were stored in ADMIN, when they were run by USER they would run in the USER context. EG, a table (call it MYTABLE) that was referenced in the procedure without a schema reference (SELECT * FROM MYTABLE) would expect to find MYTABLE in the context of the schema which called the procedure. In other words, call the procedure from USER, I expected the procedure to look for MYTABLE in USER. However, we are getting errors that indicate that even though the procedure is called from USER, it is looking for the table in ADMIN (the procedures creation context), no in USER (the running context).
QUESTIONS: How is PL/SQL supposed to operate in this situation? Are there any options/parameters that can be set so the procedure will use the runtime context for table lookup, or do we have to write dynamic SQL which will fully qualify the table with the owner schema?
Thanks for your help

Hy,
from the manual:
The AUTHID clause is allowed only in the header of a stand-alone subprogram, a
package spec, or an object type spec. The header syntax is
-- stand-alone function
CREATE [OR REPLACE] FUNCTION [schema_name.]function_name
[(parameter_list)] RETURN datatype
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- stand-alone procedure
CREATE [OR REPLACE] PROCEDURE [schema_name.]procedure_name
[(parameter_list)]
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- package spec
CREATE [OR REPLACE] PACKAGE [schema_name.]package_name
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- object type spec
CREATE [OR REPLACE] TYPE [schema_name.]object_type_name
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS} OBJECT
where DEFINER is the default option. In a package or object type, the AUTHID
clause applies to all routines.
Note: Most supplied PL/SQL packages (such as DBMS_LOB, DBMS_PIPE, DBMS_
ROWID, DBMS_SQL, and UTL_REF) are invoker-rights packages.

Question about security context in multithreading environment

I have a need to make concurrent calls to multiple EJBs in parallel threads. Let's
say I establish the security context once by creating an InitialContext with given
security principal and credential. With the security context active, I spawn multiple
threads from the current thread and in each of those threads I make a call to
a secure EJB method, which my security principal is allowed to access. My question
is, will the same security context be established in each of the spawned thread
so that my EJB calls succeed? For various reasons it's not feasible to login in
each of the spawned threads, only to login once from the main thread.
I tried this with WebLogic 6.1sp3 and it seems to work as expected. However, I
have not been able to find any documentation on how security contexts are propagated
to spawned threads. All I could find was a statement that when an InitialContext
is created, the corresponding security context becomes associated with the current
thread.
My concern is that even though it works in WebLogic 6.1, it may no longer work
the same way in WebLogic 7.0 or later. And will it work when the JNDI login mechanism
is replaced by JAAS? If any WebLogic/security guru out there could give me some
info on how WebLogic security contexts work in a multithreaded environment, I
would be much obliged.
Thanks in advance!

With the JAAS model, you should be able to get a subject once and then do a
runas in the spawned threads.

Question about global temp tables

I have global temporary table with ON COMMIT setting ON COMMIT PRESERVE ROWS. E.g.:
CREATE GLOBAL TEMPORARY TABLE admin_work_area
        (startdate DATE,
         enddate DATE,
         class CHAR(20))
      ON COMMIT PRESERVE ROWS;On application start procedure inserting data into table, on application end is DELETE statement used to make table empty.
Interestingly if application is started again (in same session!) deleted rows appear again in table before call of insert-procedure. So after call of insert-procedure data will be doubled... :(
So my question is:
Does COMMIT in this constellation making ROLLBACK of deleted rows?
Sounds unlogical to me, but appear to be like that...
Message was edited by:
Faust
Edit: ON COMMIT setting

Are you sure that the rows somehow just appear back
and it's not the application which inserts them
twice.Yes I'm sure, there is only one call of insert-procedure (on application start).
Are you using autonomous transactions for
those inserts by any chance?No.
SID is just an index into session fixed array, so the
only way to get the same SID in an instance is when
the previous session ends.
Each session array slot contains a SERIAL# field
which is zero at instance start and is incremented
every time the slot is reused by next session.
So, as long as your session exists, it is impossible
that someone else gets same SID + SERIAL# combination
in an instance.
Note that the SESSION_ADDR and SESSION_NUM give you
the address and SERIAL# of the session owning a
temporary segment.Original session exist...
Thank you Tanel for your replay!

Question about Global index and Table Partitions

I have created a global index for a partitioned table now in the future the partitions will be dropped in the table. Do I need to do anything to the global index? Does it need to be rebuilt or would it be ok if partitions get dropped in the table?

>

>
You can use the UPDATE INDEXES clause. That allows users to keep using the table and Oracle will keep the global indexes updated.
Otherwise, as already stated all global indexes will be marked UNUSABLE.
See 'Dropping Partitions' in the VLDB and Partitioning Guide
http://docs.oracle.com/cd/E11882_01/server.112/e25523/part_admin002.htm#i1007479
>
If local indexes are defined for the table, then this statement also drops the matching partition or subpartitions from the local index. All global indexes, or all partitions of partitioned global indexes, are marked UNUSABLE unless either of the following is true:
You specify UPDATE INDEXES (Cannot be specified for index-organized tables. Use UPDATE GLOBAL INDEXES instead.)
The partition being dropped or its subpartitions are empty

Question about static context when using classes

hey there.
i'm pretty new to java an here's my problem:
public class kreise {
     public static void main (String[] args) {
         //creating the circles
         create a = new create(1,4,3);
         create b = new create(7,2,5);
         System.out.println(a);
         System.out.println(b);
         //diameters...unimportant right now
         getDiameter a_ = new getDiameter(a.radius);
         getDiameter b_ = new getDiameter(b.radius);
         System.out.println(a_);
         System.out.println(b_);
         //moving the circles
         double x = 2;
         double y = 9;
         double z = 3;
         a = create.move();
         System.out.println(a);
}creating a circle makes use of the class create which looks like this:
public class create {
    public double k1;
    public double k2;
    public double radius;
    public create(double x,double y,double r) {
        k1 = x;
        k2 = y;
        radius = r;
    public create move() {
        k1 = 1;
        k2 = 1;
        radius = 3;
        return new create (k1,k2,radius);
    public String toString() {
    return "Koordinaten: "+k1+" / "+k2+". Radius: "+radius;
}now that's all totally fine, but when i try to usw create.move to change the circles coordinates the compiler says that the non-static method move() can't be referenced from a static context. so far i've seen that my main() funktion MUST be static. when declaring the doubles k1, k2, and radius in create() static it works, but then of course when having created the second circle it overwrites the first one.
i pretty much have the feeling this is very much a standard beginner problem, but searching for the topic never really brought up my problem exactly. thanks in advance!

You can't access a non-static method from within a static context. So, you have to call move() from outside of the main method. main has to be static because, in short, at least one method has to be static because there haven't been any objects initialized when the program is started. There are more fundamental problems than with just the static context issue.
I'm confused by your code though. You call create.move(), but this would only be possible if move() was static, and from what I see, it's not. Now that's just one part of it. My second issue is that the logic behind the move() method is very messy. You shouldn't return a newly instantiated object, instead it should just change the fields of the current object. Also as a general rule, instance fields should be private; you have them as public, and this would be problematic because anything can access it.
Have you heard of getters and setters? That would be what I recommend.
Now, also, when you are "moving" it, you are basically creating a new circle with completely differently properties; in light of this, I've renamed it change(). Here would be my version of your code:
public class CircleTester {
    public static void main (String[] args)
         //Bad way to do it, but here's one way around it:
         new CircleTester().moveCircle();
    private void moveCircle()     //really a bad method, but for now, it'll do
        Circle a = new Circle(1,4,3);
        Circle b = new Circle(7,2,5);
        System.out.println(a);
        System.out.println(b);
        //diameters. Don't need to have a new getDiameter class
        double a_ = a.getRadius() * 2;     //Instead of doing * 2 each time, you could have a method that just returns the radius * 2
        double b_ = b.getRadius() * 2;
        System.out.println(a_);
        System.out.println(b_);
        //move the circle
        a.change(2,9,3);
        System.out.println(a);
public class Circle {
    private double k1;
    private double k2;
    private double radius;
    public Circle(double x,double y,double r)
        k1 = x;
        k2 = y;
        radius = r;
    public void change(int x, int y, int r)
        k1 = x;
        k2 = y;
        radius = r;
    public String toString()
         return "Koordinaten: "+k1+" / "+k2+". Radius: "+radius;
    public double getRadius()
         return radius;
}On another note, there is already a ellipse class: http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/Ellipse2D.html

Question about global variables in Netbeans 4.1's debugger

so i can see the local variables, great.
how do i display the global variables when im debugging? searched help, nothing, searched the netbeans site, nothing.
anyone know?

I haven't used the 4.1 version of the debugger (I can't get it to work on a single file/class) but under 3.6 you just put the cursor over them and the values is in the tooltip.

Question about global variable scope in mxml

Let's say I have two files, myApp.mxml and EntryClass.as, as
attached at the end of this post.
Why does mxmlc complain with this error message:
quote:
/path/to/EntryClass.as(4): col: 7 Error: Access of undefined
property myChart.
myChart.graphics.drawRect(100,100,100,100);
^
According to devguide_flex3.pdf,
quote:
The IDs for all tags in an MXML component, no matter how
deeply nested they are, generate public variables of the component
being defined. As a result, all id properties must be unique within
a document. This also means that if you specified an ID for a
component instance, you can access that component from anywhere in
the application: from functions, external class files, imported
ActionScript files, or inline scripts.
So how does one reference these public variables?

Third question.

Some basic questions about rmi registry context "bind" and "lookup"

We have more processing to do than can be accomplished with a single computer. To solve the problem I've implemented a distributed computing solution using RMI. (The first time I saw RMI was about 2 weeks ago, so please bear with me!)
The implementation is a proof of concept not a fully fleshed out system. I have one "Workunit Distributor" computer and any number of "Data Processor" computers all on the same lan segment. "Workunit Distributor" and "Data Processor" computers are both RMI client and server to each other. The "Data Processor" computers are given the ip address and name of the "Data Distributor" on the commandline when they start. They communicate their willingness to receive and process a workunit to the ""Workunit Distributor" via a RMI call. Work units are sent to available "DataProcessors" and results are eventually returned to the "WorkunitDistributor" (minutes or hours later). The model program works quite well, and appears to be capable of doing the processing we need to get done.
But now that it seems viable, I've been asked to make it a little more scalable, flexible and self configuring. In particular, instead of one "Workunit Distributor", any number of "Workunit Distributors" should be allowed to show up or disappear from the lan at any time and the system should continue to function. I've worked out a good scheme for how this can be done, but I have a couple of questions about the RMI registry (registries?). I'm trying to keep from implementing some functionality that may already be available as a library or subsystem.
With my current model design, each computer binds to its own registry with a unique name. For instance:
CRDataProcessorImpl crdpi = new CRDataProcessorImpl(svr);
Context crDataProcessingContext = new InitialContext();
crDataProcessingContext.bind("rmi:"+hostName, crdpi);
Currently the "Data Processors" get the info they need for a Context lookup() of the one and only "Workunit Distributor" from the commandline. And the info the "Workunit Distributor" needs to do a Context lookup() of a "DataProcessor" is passed to it from each "DataProcessor" via a RMI call.
But in the newer (yet to be implemented) scheme where any and all "Workunit Distributors" show up and disappear whenever they feel like, the naming bootstrapping scheme described above won't work.
I can imagine a few ways of solving this problem. For instance, having "Workunit Distributors" multicast their contact information on the lan and have a worker thread on each "Data Processor" keep track of the naming information that was multicast. Another alternative (more organized, but more complex) might be to have a dedicated host with a "well known" address and port that "Workunit Distributors" and "Data Processors" could all go to, to register or look up at an application level. Sort of a "domain name service" for RMI. But both these schemes look like a lot of work to implement , debug and maintain.
The BEST thing would be if there was one plain vanilla RMI registry that was usable by all RMI enabled computers instead of having each computer have its own local name registry. In volume 2 of the Core Java2 book it says that every registry must be local. I'm only hoping there's been progress since the book was published and now a central rmi registry is available.
If you have any ideas about this I'd like to hear what you know.
Thanks in advance for any advice.
Lenny Wintfeld
ps - I don't believe web services, as full featured as it is, is a useful alternative. I'm moving 100's (in the future possibly 1000's) of megabytes back an forth for processing.

The local bind/rebind/unbind restriction is still there and it will always be there.
I would look at
(a) RMI/IIOP, where you use COSNaming as a registry, which doesn't have that registriction, and which also has location-independent object identifiers
(b) Jini.

EBS 12.1.3: a few questions about cloning

Hi,
We have EBS 12.1.3 on AIX 7.1.
A few questions about cloning from shared application tier environment to non-shared application tier environment. We have been following "Cloning Oracle Applications Release 12 with Rapid Clone [ID 406982.1]"
Source environment (shared app tier):
- Two active application nodes and LB
- One active database and one passive database setup with Oracle Data Guard.
- SSL termination at the load balancer
- PCP implemented
Target environment (non-shared app tier):
- One active application node
- One active database node
- No SSL
- No PCP
After the cloning was completed we noticed the following problems in the target system:
1) Home page cannot be accessed as application tier $CONTEXT_FILE still contains "https" and ssl termination settings.
Workaround:
Modify (with text editor) Application Tier $CONTEXT_FILE as follows.
<webentryurlprotocol oa_var="s_webentryurlprotocol" customized="yes">http</webentryurlprotocol>
<sslterminator oa_var="s_enable_sslterminator">#</sslterminator>
<login_page oa_var="s_login_page" customized="yes">http://myhost.mydomain.com:8000/OA_HTML/AppsLogin</login_page>
<externURL oa_var="s_external_url" customized="yes">http://myhost.mydomain.com:8000</externURL>
Run AutoConfig and start application tier.
Is there a better and supported solution for this?
2) Concurrent managers do not work correctly as they have still old node names (used in PCP in the source system). Workaround used:
1. Logon to EBS web GUI and remove all nodes from all concurrent managers.
2. Shutdown application tier. Verify that all concurrent managers have been shutdown. If not, kill the processes manually
3. As apps user run cmclean.sql
4. Restart application tier
Is there a better solution for this?
3) Database changes from ARCHIVELOG mode to nonarchivelog mode in the target system. Is there anyway to prevent this?
4) Also, we would like to perform a full clone (app + db tiers) from production without shutting down the application. Is this possible? What would be the best documents to describe this? In Production, we have Oracle Data Guard setup with physical standby as per "Oracle Tech Note: Business Continuity for Oracle E-Business Release 12 Using Oracle 11g Physical Standby Database [ID 1070033.1]". This can be used when performing a hot clone for the database, right? What about the application tier? Steps described in 406982.1 include running AutoConfig in which application tier should be down. Does the application need to be down when running "Maintain Snapshot Information"?
5) One final question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. E.g. https://myhost.mydomain.com:5501/em gives "Page cannot be displayed". This was working correctly last week. In Firefox, the same link is working fine. Any ideas how to fix this?
Thanks for your answers in advance.
BR,

<externURL oa_var="s_external_url" customized="yes">http://myhost.mydomain.com:8000</externURL>
Run AutoConfig and start application tier.
Is there a better and supported solution for this?No, you need to edit the context file manually and run AutoConfig.
2) Concurrent managers do not work correctly as they have still old node names (used in PCP in the source system). Workaround used:
1. Logon to EBS web GUI and remove all nodes from all concurrent managers.
2. Shutdown application tier. Verify that all concurrent managers have been shutdown. If not, kill the processes manually
3. As apps user run cmclean.sql
4. Restart application tier
Is there a better solution for this?You are following the best approach. You could update the node details from the backend if you want.
3) Database changes from ARCHIVELOG mode to nonarchivelog mode in the target system. Is there anyway to prevent this?By default, Rapid Clone will create the target database in noarchivelog mode.
4) Also, we would like to perform a full clone (app + db tiers) from production without shutting down the application. Is this possible? What would be the best documents to describe this? In Production, we have Oracle Data Guard setup with physical standby as per "Oracle Tech Note: Business Continuity for Oracle E-Business Release 12 Using Oracle 11g Physical Standby Database [ID 1070033.1]". This can be used when performing a hot clone for the database, right? Correct.
What about the application tier? Steps described in 406982.1 include running AutoConfig in which application tier should be down. Does the application need to be down when running "Maintain Snapshot Information"?You can copy the application tier node files while the application is up. And, you do not need to shutdown the application to run "Maintain Snapshot Information".
5) One final question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. E.g. https://myhost.mydomain.com:5501/em gives "Page cannot be displayed". This was working correctly last week. In Firefox, the same link is working fine. Any ideas how to fix this?
If it is working from one browser, then it should not be an EM issue. Have you tried from a different client and see if this works? Have you changed any setting in your IE browser? Please make sure you add the EM URL to the trusted sites list.

When is global context memory freed?

Hi:
I've got a package that I call for each user on logon that gets their unique ID and then sets values particular to that user in a global context after setting the CLIENT_IDENTIFIER for the session. I'm basically using the "One Big App User" approach. I'm testing the package out, making sure that attributes get set correctly by having another oracle user (TEST) loop through known usernames and having the context package set the attribute values based on the username. When control comes back to the test user I print out the values for the session. It all looks like it's working.
My question is, as I run this test program, I keep monitoring the global context memory. The amount isn't huge, but I'm wondering when it goes down. I expected it to be when the test program stopped I logged out of that SQL Plus but that didn't happen. So when does GLOBAL_CONTEXT_MEMORY get freed?
Thanks.

Hi,
Please see the below link for detailed info on global context memory release.

thank you all for helping.
I will write more information about my questions may this help others:
*{ /WEB-INF/web.xml* - The +Web Application Deployment
Descriptor+ for your application. This is an XML file describing
the servlets and other components that make up your application,
along with any initialization parameters and container-managed
security constraints that you want the server to enforce for you.
This file is discussed in more detail in the following subsection.
As mentioned above, the <code>/WEB-INF/web.xml</code> file contains the
Web Application Deployment Descriptor for your application. As the filename
extension implies, this file is an XML document, and defines everything about
your application that a server needs to know (except the context path,
which is assigned by the system administrator when the application is
deployed).
The complete syntax and semantics for the deployment descriptor is defined
in Chapter 13 of the Servlet API Specification, version 2.3. Over time, it
is expected that development tools will be provided that create and edit the
deployment descriptor for you. In the meantime, to provide a starting point,
a [basic web.xml file|http://localhost:8080/docs/appdev/web.xml.txt]
is provided. This file includes comments that describe the purpose of each
included element.
NOTE - The Servlet Specification includes a Document
Type Descriptor (DTD) for the web application deployment descriptor, and
Tomcat 6 enforces the rules defined here when processing your application's
<code>/WEB-INF/web.xml</code> file. In particular, you must
enter your descriptor elements (such as <code><filter></code>,
<code><servlet></code>, and <code><servlet-mapping></code> in
the order defined by the DTD (see Section 13.3).

Tomcat Context Descriptor
bq. A /META-INF/context.xml file can be used to define Tomcat specific \\ configuration options, such as loggers, data sources, session manager \\ configuration and more. This XML file must contain one Context element, which \\ will be considered as if it was the child of the Host element corresponding \\ to the Host to which the The Tomcat configuration documentation contains \\ information on the Context element.
}from tomcat documentation

I want to use ant that become with netbeans 6.1.can anyone give me information about how to do that.
thank you again

Sql developer: question about exporting data

Hi,
we're recently working with sql-developer. i've got a question about how we can export query results to txt/csv files for use in other applications.
First a problem: if we start a query that looks like this:
select * from
select * from A where start_date = &date
) a,
select * from B where start_date = &date
) b
where a.name = b.name
Sql-developer asks twice to input a value for the variable 'date', although it's the same variable and it's supposed to have the same value.
We solve this by making a script:
first we define the variable, then we put the query.
When we start the script, the query runs ok and sql developer asks to input the value for the variable once.
But now the result of the query is shown in the script output. The script output seems to be limited in number of lines and difficult to export.
So my question is: what's the best way to export query results to txt/csv files, avoiding the problem mentioned above?
i hope there is a solution where we can use a single query or script.
Thanks in advance!

Using bind variables like ":date" should solve the problem of being asked twice for the same thing.
Executing the query normally (F9), gives you the export options you require through the context menu inside the Results grid.

K.

A question about BC 400 training program

Dear all,
I have a question about SAP taining program for ABAP. My manager will soon register me for the training program BC 400, which seems to be the start point for those who don't know anything about ABAP. I was looking at the course description page and I saw that the course is provided as VLC (Virtual Class). As I understood is that the student connects from his workstation to the training center, so it is distant training program.
I think it would be more interesting for me to be directly in the classroom with teacher face-to-face.
Therefore, my qestion is the fact that a training program is VLC, does it mean that it is no more possible to attend directly in classes ? or is just for those who may not want for some reason attend directly to the class?
Thanks in advance,
Dariyoosh
