Access a RoleMapper instance directly?

Is there a way to programmatically access a weblogic.security.spi.RoleMapper instance directly?
I have an existing portal app in which roles were stuffed into the UUP through direct database access. I'd like to implement a RoleMapper for the roles, and as an intermediate solution, have the UUP call the RoleMapper instance directly to fill up its roles. Then, the application team could switch their code on their own schedule for referring to the RoleMapper/isUserInRole interface directly. Is that possible? Thanks.

You can't do that like this. A normal process runs in the user environment it is started in and can't be accessed by another user. The only architecture I could see working here is to separate the application in the core engine that does all the acquisition and logging, and an UI part that can connect to the core engine through any Interprocess Communication like TCP/IP. You then can setup the core engine to start as a system service so it can be connected to from the UI application and controlled to start and stop it's acquisition as well as retrieving data for viewing.

Accessing application module instances directly from the AMPool

Hi!
I´m want to create an Application Module Pool Monitor, actually I need to know how many fetched rows an Application Module instance has.
I made a jsp, that do the following:
ApplicationPool pool = (ApplicationPool)poolMgr.getResourcePool(poolname);
int instanceCount = pool.getInstanceCount();
for (int i = 0; i < instanceCount; i++){
ApplicationModule am = pool.getInstance(i);
and then works with the am instances, calculating the rows that each VO has fetched.
Now, It is not yet clear to me if, when I use "pool.getInstance(i)",
I'm locking the instance that is being use by another session (an user session), or trying to get a lock,
and possibly creating a deadlock. Or the AMPool administrates the lock and I don´t need to worry about it.
Thank in advance, and sorry for my bad english!
(i forgot to mention, I´m using adf - bc 10.1.2 )

Sure, we are having RAM problems, sometimes, and for reasons that are still unclear, a process begins to consume memory.
What we need rigth now, is a tool that tell us how many rows in memory has each user, and which ViewObject is creating them. The idea is to make some kind of monitor that shows that, the AM that each user has, an the state of their VOs.
I used the JSP in this page as a reference:
http://radio.weblogs.com/0118231/stories/2004/05/10/gettingApplicationModulePoolStatisticsToAidWithSizeTuning.html
I´m not trying to create a new AM management mechanism, simply a tool that shows the status of the application (and perhaps allows me, for instance, to clear the cache of a VO that has to many rows fetched).
In my JSP I obtain an instance of the AMs using "pool.getInstance(i)", and access then the associated VOs. But I don´t know if accesing the AMs this way could create problems with users that have an AM assigned to them, for example, a deadlock.
Thanks!

Accessing an ASM Instance via OEM

Gaining access to an ASM-managed database instance via Enterprise manager is done in the same way as accessing a "normal" RDBMS database: http://<host>:<port>/em/
Is it also possible to access the ASM instance itself via the OEM? If so, what's the typical URL/port for access?
I have not seen this documented, and I wonder if it's possible to access the ASM instance via OEM after all, or can you view/manage ASM instance information only via SQL statements.
Thank you.
John

That makes perfect sense... nufortunately, I'm sitll confused. I just found a series of screen shots that explicitly say "Database Control", and the home page shows the "+asm" link I mentioned in my earlier post. What's more: these screen shots are directly from Oracle! Their "Oracle By Example" series has an entry called "Creating and Managing ASM Disk Groups", and the section called "Viewing Disk Groups" has a series of shots that clearly shows first an ASM-managed instance, and then the ASM instance itself, being directly managed by Database Control.
I wish someone from Oracle, or someone who has seen this in action, would chime in and let us know how it works!
Thanks.

Regarding Access of Aborted Instance

Hello,
I have a particular query regarding accessing an aborted instance.
I have an instance which gets aborted after terminating correlation for the same. Now i want to access the options available in the "Select action" drop-down for the particular instance.
But instead of functioning in the desired manner, i get the following exception:
Unexpected error during interactive component execution.
I get the following warning:
Error workspace-1264459074941
Unexpected error during interactive component execution.
Caused by: Ensurement failed: To set the instance as ABORTED, the instance must be ABORTING or in EXCEPTION, but it is RUNNING

I had this problem today and was looking here for a solution. I eventually found that in my case it was that I had added a Port directive in an included Apache configuration file, and this caused problems because there was already a Port directive in the mail httpd.conf file.
Apparently any such duplication of one-only configuration directives will cause this error, even if the Apache configuration parses OK. Oracle HTTP Server can even start up OK with such duplication in the configuration files, but you run into trouble when using dcmctl or IAS Console to deploy/undeploy ear files etc.
I removed my addition and this "There are multiple instances in the input config file" error disappeared.
However, I still had a problem with an OC4J container/instance in which I had tried to undeploy an application; although the operation had failed and given me that "multiple instances" error message, the application had disappeared from the management interface so I couldn't clean it up, but I also couldn't deploy it again, as I got an error saying it had already been deployed. The solution for me was to delete the OC4J instance and recreate it. Which unfortunately meant I had to configure it all over again.
Hope this helps someone.

Eldon

Problem in accessing second database instance on same host (ORA-12514)

Hi,
I had a database ICMDB installed on my machine. After that i created a second database instance (Service name: BI_APPS) using DBCA on the same machine. Using NETCA i also created a new listener OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER on port 1522 on my machine. Then i configured this listener to listen for connections to service BI_APPS by adding the following to my tnsnames.ora:
BI_APPS_LISTENER =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
Then i changed the port in my tns entry for BI_APPS to 1522 as follows:
BI_APPS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BI_APPS)
I then restarted the following services:
OracleOraDb11g_home1TNSListener
OracleServiceBIAPPS
OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER
After this, when i try to access my first DB ICMDB via toad, the connection is successful. However, when i try to access the service BI_APPS i get the following error:

Hi Ed,
I understand your point, however whenever i have tried to use the same listener to access my second instance, this is the error i have always received:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
That does not indicate you need a second listener.
And, after deleting the listener.ora file ,if i try the the command lsnrctl start, i get the error:
ORA-12560: TNS:protocol adapter error
Hence i restored the files. What do i do?
I've never experienced a 12560 trying to start a listener. I'll need to see if I can create a test system on Windows and try to recreate. Will be a good subject for my blog, that has been too long with no new content.
Since this is windows, I'd first check that the Windows service for the listenr is started.
Whatever, multiple listeners is NOT the solution.

Is there a way to access ABAP OO instances from a batch job report

Hello,
I am looking for a way to access ABAP OO instances from a batch job report. My circumstances are the following:
I have got some ABAP OO coding that identifies other objects (class instances) that have to be processed (they have a DoIt method that does some calculation). As this processing is time consuming and performace relevant I have to parallelize this in batch jobs. This batch jobs however can only be "simple" ABAP reports according to SM36. The problem is now that I dont really know how to tell the batch job report what objects to process. Somehow I have to access theses instances from that batch job report.
Does anybody have an idea?
Greetings

Hi David,
thanks a lot for your help. After a lot of searching on the net this seems to be the only way to cope with it. However I am not sure about the locking mechanisms and if its suitable for mass data processing. In the help page you suggested the following is stated which I do not fully understand::
"The current lock logic does not enable you to set specific locks for the following requirements:
·        Many parallel read and write accesses
·        Frequent write accesses
·        Division into changeable and non-changeable areas
Although the lock logic makes the first two points technically possible, they are not practical because most accesses would be rejected."
Does this mean
a) if I dont want to set "specific locks" for frequent write accessess I am fine
or
b) I am discouraged from use shared memory technics for frequent write accessess?
In the latter case I will have a problem...
What do you think?

How to access AM/VO instance from a Java Service class

Hi,
I have a Java service class that is loaded by Java ServiceLoader (http://download.oracle.com/javase/6/docs/api/java/util/ServiceLoader.html) at run time, and I need to access database tables inside that service class. So is there any way that I can access AM/VO instances from that Java class in order to read database table? Thanks.

You can access an application module with the the two methods below:
    YOURAppModule mAM;
    public void setUpAM()
        throws NamingException
        try
            String AMDefName = "YOUR_APP_DEF_NAME";
            Hashtable env = new Hashtable(2);
            env.put(JboContext.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
            env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
            ApplicationModule am = null;
            InitialContext ic = new InitialContext(env);
            ApplicationModuleHome home = (ApplicationModuleHome) ic.lookup(AMDefName);
            am = home.create();
            // Connect the AM to a database connection
            String jndiDB = "jdbc/HRDS";
            am.getTransaction().connectToDataSource(null, jndiDB, false);
            boolean connected = am.getTransaction().isConnected();
            mAM = (YOURAppModule) am;
        catch (NamingException nex)
            // do some error processing
            throw nex;
        catch (Exception eee)
            // do some error processing
            throw eee;
    public void tearDownAM()
        if (mAM != null)
            if (mAM .getTransaction().isConnected())
                mAM .getTransaction().disconnect();
                mAM .remove();
    }You find the YOUR_APP_DEF_NAME in your application module under 'Configurations' -> AppModuleJndiName.
Make sure you tear down each AM you set up. Otherwise you are running out of resources pretty fast.

I want to access that BEA instance variable inside of a external java class

Hi,
This is N.pradeep. I am a java programmer, and I am new to BEA AquaLogic BPM studio5.7. I have a question regarding how to retrieve an instance variable of BEA Aqua Logic to an external Java Program. i.e. I want to access that BEA instance variable inside of a external java class, and vice versa.

You can use PAPI or PAPI-WS for accessing BPM instance variable from a Java code, thougt I am not sure how the reverse will be done. Assuming that you are aware aof PAPI-WS and have created the necessary stubs out of the PAPI-WS WSDL using Axis, you can access instance variables using the API's or operations defined therein.
Thanks and Regards

Why can private variables be accessed by other instances?

From an OO design perspective, I'm sure this makes sense, but perhaps somebody could articulate it for me so that I can understand the rationale.
I can see that one way of looking at encapsulation is that the object itself should be encapsulated and if you have 2 Person objects, why should one Person be allowed access to another Person's private data?
Why is this not how Java decides to implement access modifiers (i.e. not a per-instance basis)?...I have no idea how other languages do it because I'm new to all this, but perhaps you can explain for me.

I don't know why it was designed that way, but
consider this:public class Example {
private int value = 42;
public void setAnotherValue(Example ex, int
nt newValue) {
ex.value = newValue;
Thanks for your example. Looking at it, it makes me realize that this per-class access is specially meant for access to other instances, because otherwise the method would just look like this, correct?
public void setAnotherValue(int newValue) {
   this.value = newValue;
}How would the runtime check you mentioned look? I couldn't figure out which of the following two you had in mind and are appropriate:
public void setAnotherValue(Example ex, int newValue) {
   if (ex == this)
     ex.value = newValue;
else
     throw new RuntimeException();
}or this...
Example e1 = new Example();
Example e2 = new Example();
if (e2 != e1) throw new RuntimeException();
e2.setAnotherValue(e1, 57);

Accessing a movieclip instance created with AS.

If I attach a new movie clip and give it a name by concatenating the instance name with a variable number (such as "myMovie + myVar" so that I get "myMovie1", "myMovie2", etc.), how do I then access the resulting instance in order to assign properties? MyMovie + myVar._x = 500 not surprisingly doesn't work. I presume I need to assign the value to a string variable, and then somehow assign that variable as the instance name of the movieclip?
Thanks.

that's incorrect syntax and contains a typo. try:
var myVar:Number = 1;
this.attachMovie("Square_mc","Square_mc"+myVar,this.getNextHighestDepth()) ;
this["Square_mc"+myVar]._x = 300;

Unauthorised users accessing iviews through a direct URL

Hi,
How do you prevent unauthorised users from accessing iviews through a direct URL? e.g. From the BeX Web Template on testing a query a URL is known, this URL can then be used by user who have no rights to view/ execute this report (after portal logon).
Can security zones be defined for the BeX iviews? If yes, how? Does setting the parameter Dcom.sap.nw.sz=true solve the problem?
Appreciate your input.
Many thanks,
Dharmi

Hi Bharath,
Thank you for the input.
Can you please be more specific as to which BW component ?
I navigated to
Go to permission editor: 'System Administration' -> 'Permissions' -> 'Portal Permissions'.
folder: 'Security Zones' -> 'sap.com' -> 'NetWeaver.Portal' -> 'high_safety'
There the rights are ok.
Best regards,
Dharmi

Is there a way to configure iCloud to allow different email addresses to access one iCloud instance?

I would like to set up iCloud on my home PC using my Apple ID (email account). I would also like to set up my son and daughter to be able to access that iCloud instance from their iPhones and Macs - but it seems like I have to give them access to the email account that I use as my Apple ID.
Is there documentation that will show me how I need to configure the iCloud account that will grant them access, but not necessarily using my email account for this? I am not finding this kind of information in the online help files - although maybe I am looking in the wrong place.
I would like to set up my home Windows PC, two Macs, and 2 iPhones on the iCloud instance - with the probability of adding another iPhone and an iPad.
If I create a new apple email ID to create the iCloud account, will that require me to change my whole Apple ID as well?
Thanks for any help you can offer.

Thanks Roger.
I don't have as much an issue with the access to the Apple account so much as setting it up on my kid's iPhone (say...) also pulls my personal emails too. I want to give them access to the iCloud - just not my emails!
Should I do this by setting up an alias in iCloud and setting their access using *that* ID?

[svn] 4222: Now that Shader is a first class Embed, we' ve modified the interface for ShaderFilter to accept a Shader instance directly (or Class representing a Shader Embed).

So this may be a kludge, but eventually I got it. In this case the appDelegate is waking up NIB's and subsequently causes the 'viewDidLoad' method to be called in the Object that manages the NIB.
The problem was how to get 2 objects that had each been woken by the appDelegate to be aware of each other and be able to use methods in the other.
In the appDelegate
@class AViewControllerObject;
@class A2ndVCObject;
@interface AppDelegate
AViewControllerObject * aViewControllerObject
A2ndVCObject * a2ndVCObject;
@property (
@property (
@end
@implementation AppDelegate
@synthesize aViewControllerObject;
@synthesize a2ndVCObject;
//instantiate the NIB's and place in the 'controllers' array
aViewControllerObject = [[AViewControllerObject alloc]
initWithNibName:@"aViewControllerNIB" bundle: nil];
[controllers addObject: aViewControllerObject];
a2ndVCObject = [[A2ndVCObject alloc]
initWithNibName:@"a2ndVCNIB" bundle: nil];
[controllers addObject: a2ndVCObject];
So to make the 1st ViewControl Object aware of the 2nd viewControl Object, make the following method call from the appDelegate:
[aViewControllerObject assignA2ndVCPointer: (A2ndVCObject *) a2ndVCObject];
....and in aViewControllerObject:
@class A2ndVCObject;
@interface AViewControllerObject
A2ndVCObject * a2ndVCObject;
@property (
@end
@implementation AViewControllerObject
@synthesize a2ndVCObject;
- (void) assignA2ndVCPointer: (A2ndVCObject *) pointer{
self.a2ndVCObject = pointer;
So this may seem bogus to 'old hands' but its the only way I could figure it out.
If anyone has a better way, I'd love to hear it!!

Managing Multiple threads accessing a single instance of a class

Hi,
i have to redesign a class, say X, in such a way that i manage multiple threads accessing a single instance of the class, we cannot create multiple instances of X. The class looks like this:
Class X{
boolean isACalled=false;
boolean isInitCalled=false;
boolean isBCalled=false;
A(){
isACalled=true;
Init(){
if(!isACalled)
A();
B();
C();
isInitCalled=true;
B(){
if(!isACalled)
A();
isBCalled=true;
C(){
if(!isACalled)
A();
if(!isBCalled)
B();
}//end of class
Init is the method that would be invoked on the single instance of this class.
Now i cannot keep the flags as instance variables coz different threads would have differrent status of these flags at the same time, hence i can make them local, but if i make them local to one method, the others won't be able to check their status, so the only solution i can think of is to place all the flags in a hashtable local to method INIT AND INITIALIZE ALL OF them to false, as init would call other methods, it would pass the hashtable reference as an additional parameter, the methods would set the flags in the hashtable and it would be reflectecd in the original hashtable, and so all the methods can have access to the hashtable of flags and can perform their respective checks and setting of flags.
This all would be local to one thread, so there's no question of flags of one thread mixin with the flags of some other thread.
My question is :
Is this the best way, would this work?
In java, everything is pass by value, but if i pass the hashtable reference, would the changes made inside the called method to the hashtable key-value would be visible in the original hashtable declared inside the calling method of which the hashtable is local variable?

In Java object variables are passed "by copy of reference", and primitive variables "by value".
The solution with HashMap/Hashtable you suggest is ok, but I think you should read about ThreadLocal class:
