Dynamic proxy, several instances, same name, diff ids?

I'm using a dynamic proxy with a simple invocation handler. Using the proxy for several instances of the target object should yield multiple instances of the proxy. In the debugger, each proxy instance is named $proxy0 with different ids. Can someone please elaborate on this? Specifically, the Proxy instance is created using the target object. Thus, how can each proxy instance have the same name, when different target objects (of the same type though) are used to construct the Proxy object? Is the Proxy instance the same regardless of the target object?
I : interface
T: target class
pseudo thing:
<code>
T t1, t2, t3 ... new ...
I i1 = (I) Proxy.newInst...(..., ..., t1)
I i2 = (I) Proxy.newInst...(..., ..., t2)
I i3 = (I) Proxy.newInst...(..., ..., t3)
Each i has name $proxy0 with different id. For instance: i1-> $proxy0 id=68, i2 ->$proxy0 id= 32, etc.
</code>
Insight is appreciated!

is it the same proxy that is instantiated three times (obviously)?It is the same proxy class that is instantiated three times. Obviously. Because that is the only meaning for 'instantiate' in Java.
But how can that be when the target object for each Proxy instance is different?Because they are three different instances of the same class, each with a different target object.
What's the problem here?

Two instances same name and diferent homes

Hi everyone,=
I already read this interesting post:
Creating two instances of same name in a single ORACLE_HOME ?
After reading it I have the following question:
Can this apply using the same ASM Instance but with diferent disk groups for each database?
I'm thinking in this following configuration:
ORACLE_HOME1 => 11.2.0.1
GRID_HOME1 => 11.2.0.1
DISK GROUP 1, DISK GROUP 2 for DB1 in ASM
ORACLE_HOME2 => 11.2.0.3
DISK GROUP 3, DISK GROUP 4 for DB1 in ASM
Both databases using the same ASM instance but diferent disk groups.
Could this be posible?
Thanks in advance!
johnxjean

Thanks Balazs Papp for your quick response.
In the scenario there is only one ASM instance and there are two databases DB1 and DB1 (same name) maybe I'am trying to upgrade or simply restoring with RMAN an old backup for DB1 from ORACLE_HOME1 in ORACLE_HOME2 with the same oracle version or later.
Now, in the original post unix can create processes for instances with the same name but with distinct ORACLE_HOMEs.
So, can ASM serve two databases with the same name, using the same ORACLE_SID but diferent ORACLE_HOMES? or Is this only posible using only filesystems?
Thanks in advance.

Albums with same name diff artist appear as the same album in iphone

I have four albums named "greatest hits" all from different artist (smashing pumpkins, blink, rhcp...), in my itunes library they appear ok and not as one whole album, when I synch, in my iphone I see the four of them with their respective covers and such, BUT under each title no matter the artist, there are ALL THE SONGS IN ALL THE ALBUMS named "greatest hits".
in other words, I have in my iphone 4 albums named "greatest hits" under 4 different artist, but in everyone of them, I have the same songs, which are all the songs in all the "greatest hits" albums.
why does this happen? how do I fix it other than changing the album titles?
thanks!

You've run into one of the "features" of the iTunes/iPod family. I'm afraid renaming the album titles is the only option. See my previous post on Grouping Tracks Into Albums, in particular the topic One cover, too many tracks.

Is it possible to have 2 instances with the same name but different edition in the same server?

Hi everybody!
I have in a little trouble ....
*** Scenario.
Oracle Enterprise Edition 11gr2 over Oracle Solaris 11
3 instances: PROD, QA, DEV
1 ASM instance
Listener ports: 1520, 1530 & 1540
 Those are production system
*** The problem:
Customer can't pay Oracle EE, they want to change to Oracle Std One
Limitations:
I cant have a similar system to test.
*** My idea:
Install Oracle Std One, in the same path:
/u01/app/oracle/product/11.2.0/db <-- EE
/u01/app/oracle/product/11.2.0/db_one <-- Std Ed One
ASM:
/u01/app/11.2.0/grid <-- EE +ASM
/u01/app/11.2.0/grid_one <-- Std Ed One +ASM1
Create databases:
Asign similar disks to +ASM1
Create DGs on +ASM1
Create databases: PROD, QA, DEV for Std Ed one
- is it posible that they have same instance name?
- if not, i suppose create as: PROD1, QA1, DEV1
Configure Listener port : 1521, 1531 & 1541
Migration technique:
Create Tablespaces, schemas
Lock users in EE
down listener: 1520, 1530 & 1540
Import data of final users in a window maintanance
configure and up listener: 1521, 1531 & 1541
Customer should test access and apps in new
Please tell me if my Idea is reallistic, all comments are going to be very apreciated.

sol.beach
I suppose end customer use a port per database in order to separate in a logical way the access to the databases,
i mean PROD, QA & DEV has the same users.
Hemant K Chitale
1. I've seen physical servers with 3 ASM instances: +ASM1, +ASM2, +ASM3
 on Solaris & Oracle 10g, I suppose is posible on 11g
2. The sever has occupied 2 sockets (2 physical CPU), so I can use Oracle Standard Ed One.
JohnWatson2
Thanks for your comments.
WadhahDaouehi
1. - You cannot run two ASM instance simultaneously on one Server, but you can run many Oracle database simultaneously
 on the same server which they use the ASM as storage type.
As a mentioned to Hemant K Chitale, I've seen a system with several instances running
About
 "you can run many Oracle database simultaneously on the same server which they use the ASM as storage type."
I'm not sure if i can use the same ASM which is part of a current Enterprise Ed over the new installation with Oracle Std Ed One.
2. - Why you want the same instance name?
If it is about the service name, which has by default the same instance name, just you can create a different instance name
and create the service name with the name that you wish.
SQL> alter system set service_names='instance_name';
Is a similar name, not the same
PROD, QA & DEV
PROD1, QA1 & DEV1
I consider add "1" at the end to refer "Oracle Standar Ed One"
But I agree with you, i can customize throught service_name.

How to create device IDs with same name

i am using SE 3310 and its creating different device ids for each node sharing it . since I will be building a RAC enviornment I need these IDs/name to be same .
for example on one node the lun id is /dev/rdsk/c3t0d0s6 but the same lun id on node 2 is /dev/rdsk/c2t0d0s6.
In past with an old storage array I fixed this issue by creating links in /dev/rdsk for c3t0d0s6 ---> c2t0d0s6.
my question is : is there a way in SE3310 that device ids get created with same name or do i still have to rely on creating these soft links ?
thanks
Note: since i need the answer to this quickly i will wait a while and then post this question in other forums and i will update the question here with the answer .

This could be a Solaris (I presumed) O.S. question rather than SE3310 or storage question.
The logical device (/dev/[r]dsk/*) is the work of the O.S. when it first configures the device, in this case the LUN from your SE3310.   I can go in depth on how the cX number happens (due to device probe order, driver differences, history of device discovery due to need of persistent device naming, etc...) but ... it's a really long story and is really quite irrelevant and most people should not be interested...
If you have COMPLETELY identical servers, i.e. identical hardware down to specific HBA in specific slot are the same,   and if you make sure that luns are presented to all servers exactly the same way, same order, and any changes are seen by all servers in the same sequence, in theory, all /dev/rdsk/* devices will be consistent across servers.
But that's still rather irrelevant.    Application that is designed to work in a redundant environment should not be dependent on logical devices like /dev/rdsk being the same.
So ... in effect this is also not a question for the Solaris forum, but rather a question for those familiar with RAC, how to configure such that device access is done "safely" through actually identifying the lun rather than assuming /dev/rdsk are consistent.

Can I create a lot of instance with the same name?

I have, for a project in my studies, to create a map for an adventure game. I must create monsters on this map. For this I use a class that I called Creature. In my class Map i have to initialise the monsters but I
choose their quantity with Math.random() so I don't know how much the map will contain. If in a loop I do: Creature monster = new Creature(); will I have different instances with the same name(I doubt)? Will I have one monster re-created in each iteration of the loop? How can I do to have different monsters in different places (my map is a matrix 2x2)?

You would have many Creature references made, but only one variable to hold them, and it would go out of scope outside your loop. You could create a Creature array or use a List (both defined outside your loop) - as
// array
int numCreatures = randomGeneratedCreatureQuantity();
Creature[] monsters = new Creature[numCreatures];
for (int j = 0; j < numCreatures; j++) {
monsters[j] = new Creature();
// Or a list
int numCreatures = randomGeneratedCreatureQuantity();
ArrayList monsters = new ArrayList();
for (int j = 0; j < numCreatures; j++) {
monsters.add(new Creature());
}Good luck

Multiple instances of one app of the same name

Hello,
we have few FMS/AMS servers, versions 4, 4.5 and 5, running some kind of internet TV tubes on them.
Each tube is supposed to run as unique instance of a Tube app, with unique settings for publishing to CDN (Akamai).
Sometimes following scenario happens: We reload the stream via administration console or administration API with use of reloadApp command, instance starts closing sequence, even triggers onAppStop event. But as the new instance starts, the old process wakes up again and lives together with the new one - when I check then throught administration API with use of getActiveInstances command, it shows me more instance of the same name as result - for example:
-<data>
<_0>tv_app/tube25</_0>
<_1>tv_app/tube2</_1>
<_2>tv_app/tube21</_2>
<_3>tv_app/tube2</_3>
<_4>tv_app/tube2</_4>
</data>
From logs I can see that each of that instances runs under different process ID (x pid column).
This is quite unpreffered behaviour, as with the same connection settings the multiple instances steals the connection to CDN entry point from each other which causes problems and unpredictable behaviour...
I have following questions related to this:
1. - Why the onAppStop is triggered when using reloadApp and unloadApp commands or buttons in admin console, when documentation says that this event should not be triggered on these ocassions (see http://help.adobe.com/en_US/adobemediaserver/ssaslr/WS5b3ccc516d4fbf351e63e3d11a11afc95e-7 edfSSASLR.2.3.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7fe2SSASLR.2.3)
2. - How is it possible that system runs more instances of the same app with the same name? How to avoid such behaviour?
I already noticed following aspects to have influence on the possibility to run multiple instance with the same name and got rid of them but problem still persists:
- case sensivity of app name (one client connects to TV_app/tube2 and other connects to tv_app/tube2)
- using false as return value in onAppStop event handler - when reloaded, new instance is started but the old one persists
I am very eager to hear some explanation or clarification of such logic as it comes to me as some kind of internal bug as I have found everywhere that the instances names should be always unique....
Thanks

I just want to note that my recommendations led my clients to purchase more than 5 licences of FMIS/AMIS througt the time.
As I see how low is the passion to react to any problem on Adobe side, I would have probably changed my mind.
This is really pain in the *** as any call to adobe official contact (taken on mind that to find one is a big quest by itself) lead just to reply "pay nasty amount for our consultancy Sir!" and it does not look any better here....
I am no novice on FMS/AMS platform, working with it more than 6 years throught many projects and I would not ask for some stupid questions which could be solved just by looking to documentation or could be solved by some performance eperience.
I am really upset for this :/

Writing schema for multiple elements with same name with diff. content

following is the XML file,
<?xml version="1.0" encoding="utf-8"?>
<e-abstract xmlns="http://www.citicorp.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="Deed.xsd">
<deed>
<deed_type>
<deedtyp name="Quit Claim" value="Q" />
<deedtyp name="sheriff's deed" value="Sheriff" />
<deedtyp name="Warranty" value="W" />
</deed_type>
<deed>
</e-abstract>
--- end----
in this I have 3 elements of deedtyp , how i can write them in .xsd file as these elements have same name?Please help, if u have idea about this...
i have written .xsd up to deed_type,
----Deed.xsd----
<? xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.citicorp/2001/XMLSchema"
targetNamespace="http://www.citicorp.com"
xmlns="http://www.citicorp.com"
elementFormDefault="qualified">
<xs:element name="deed_type" type="string" use="required"/>
<xs:simpleType name="string">
<xs:restriction base="xs:string">
</xs:restriction>
</xs:simpleType>
</xs:schema>

I don't know the exact and complete specification of your intended schema...
anyway, from what I can see in your post, I assume that
<deed>
 <deed_type>
 <name>Quit Claim</name>
 <value>Sheriff</name>
 </deed_type>
 <deed_type>
 <name>sheriff's deed</name>
 <value>Sheriff</value>
 </deed_type>
 <deed_type>
 <name>Warranty</name>
 <value>W</name>
 </deed_type>
</deed>would be the "proper" way to go...
which makes your "deed_type" a complexType, including a sequence of two kinds of xs:string elements : "name" and "value"

How do you force instances with the same name on the same layer to update?

Maybe someone can tell me why flash doesn’t redraw
components’ x,y positions if they have the same instance name
and are on adjacent frames? (movieclips work fine, just not
components) If I have a button on frame 1 and a button on frame 2
both with the same instance name but different locations on the
stage, frame 2’s button doesn’t show up in the position
I placed it, it stays at the position of frame 1 but still has the
properties of frame 2’s button. The label changes and
everything. If I stick a button on a frame in between and give it a
different instance name there is no problem. I thought it might be
the style manager bug
http://www.gskinner.com/blog/archives/2007/12/cs3_component_b.html
but it didn’t seem to affect. This happens for textareas too
and probably all components although I haven’t tried them.
I’ve tried using drawNow() and validateNow() with no luck
either
http://www.adobe.com/devnet/flash/articles/creating_as3_components_pt3_05.html
Thank you!
// put this on frame 1 along with a button on the stage with
instance name: b
function doit(event) {
if (currentFrame == 1)
gotoAndStop(2);
else
gotoAndStop(1);
b.addEventListener(MouseEvent.CLICK, doit);
stop();
// put another button on frame 2 along with this code and
also make it’s instance name: b but move it so it’s not
in the same x,y coordinates as the button on frame 1
stop();
Something possibly related. I have a movieclip on a layer,
one instance with name “a” on frame 1 and one instance
with name “a” on frame 2 and it has event listeners
inside it that update something on the movieclip. Unless I put the
movieclips on separate layers the event listeners won’t reset
each frame. (example: a button with a tooltip onmouseover that you
want to change the text of from frame 1 to frame 2) You’d
think if they were on separate keyframes at least but no, they need
to be on separate layers too.
I want the movieclip to update each frame. Any ideas?

instances (whether components or not) with the same name may
or may not be the same instance. it depends upon how they were
created.
for example, if you create an instance on frame 1 of your
main timeline, give it an instance name and then create a keyframe
on frame 2, the two instances will be the same.
but if you create an instance on frame 1 of your main
timeline, give it an instance name and then create a blank keyframe
on frame2 and create another, what you think is a duplicate,
instance and give it the same name, it will be a different
instance.

Dynamic Internal Table with the same name

Hey Guys
I have a question.
I know that we can create dynamic internal table taking a struct dynamically.
But I have 2 ques on the same subject.
1. Can we create an internal table based on a type that we have locally declared eg
types: begin of ty_demo.
 var1(1) type c,
 var2 type p,
 end of ty_demo.
2. If an internal table is already declared based on the above type say data: i_tab type standard table of ty_demo.
 If i need to enhance the struct of this internal table. Can i do that by dynamically redefining it based on a different structure but keepin the same name i_tab.
In a nut shell I cannot change the name of my itab but I want to enhance the structure.
I Hope I am clear.
Help will be greatly apprcieated.
Thanks
Sameer

hai.
we can create an internal table based on a type that we have locally declared, but you have to use data instead of types like.
data: begin of ty_demo.
var1(1) type c,
var2 type p,
end of ty_demo.
check the example notes for dynamic itab .
Dynamic internal table is internal table that we create on the fly with flexible column numbers.

How to install several instances of the same application on a computer?

Hej,
I have an application in LV 2009, where I have created an installer. The installer installs to a directory called \Receiver relative to the Program Files directory. If I install this once to a computer, everything is OK.
However, I want to install the same application twice on the same computer. There should be no conflicts between the two applications, since I can configure them to work on different directories and ports. But if I call the installer again, and selects another directory, nothing is installed and I get the message "Installation Summary - No software will be installed or removed". It seems like the installer ignores that I have selected another directory, and just uses the default directory, relative to the Program Files directory.
Anyone knows the trick, how to install several instances on the same computer ?
BR, Jan
Jan Nielsen
Freelance system analyst and LabVIEW programmer

Hi Jan,
This is so because each installer has a GUID that is used to check whether the application needs to be upgraded or not. (It's a Microsoft function).
What you can do is create a new installer with a different GUID (copy the installer in the projects), and check witha text editor whether this GUID has changed.
But any specific reason you need two seperate installs? You can run the application twice with a specific INI token:
allowmultipleinstances=True

Several instances using same port question

Good Morning,
I am going to have to create several instances on one box using solaris 10 zone technology. Each zone haveing it's own instance. I need to confirm whether or not that all those instances can use one listerner or does each instance need it's own separate port such as 1521, 1522 etc. for it's listener.
Your opinion and recommendation on this matter will be much appreciated.

 Hi,
 
 As you are going to be using Solaris Zones would you really want to have one listener for all of the instances?
 
 Surely the point of using Zones is separation of the environments so why would you want to try and break that by not having separate listeners? If you aren't interested in isolating the environments then Zones seems like an added headache you can do without.
 
 On the question of ports... each Zone is going to have its own IP address so it really doesn't matter what port you choose. They could all have the same port for their individual listeners or they could all have different ports. Makes no odds really.
 
 Hope that helps.

Mounting multiple directories with same name on different severs to a single mount point on another server

We have a requirement where in we have multiple solaris servers and each solaris server has a directory with the same name.
The files in these directories will be different.
These same name directories on multiple severs has to be mounted to a single directory on another sever.
We are planning to use NFS, but it seems we can not mount multiple directories with same name on different severs to a single mount point using NFS, and we need to create multiple mount points.
Is there any way we can achieve this so that all the directories can be mounted to a single mount point?

You can try to mount all these mount points via NFS in one additional server and then export this new tree again via NFS to all your servers.
No sure if this works. If this works, then you will have in this case just an additional level in the tree.

I must say. I am equally curious about this. i've played a lot in Communigate and it is easy to do there but how does one do this in apple mail?

Iphoto seems to be deleting old (several years old) images that hav the same name as new images being loaded. how can i fix this?

I was browsing some old photos in iPhoto11 and started getting 'image not found' errors. After much investigation, rebuilding thumbnails and extracting photos using fatface iphoto library manager it seems that newer photos with the same name as very old photos (Canon camera naming scheme IMG_nnnn.jpg) have caused the old photos to be deleted? I thought iphoto handled this situation but it seems not.
I never got any error or warning messages on importing the newer photos. Naturally the old ones have been in there for years and were originally imported using older versions of iphoto.
As it happens I do have all these old photos stored elsewhere so its not a case of panicking but I could do with a solution going forwards.
Has anyone else encountered this (and of course if so how did you resolve it?)
TIA
Paul

Every new import to iPhoto goes into a new folder on the HD, so no, iPhoto doesn't overwrite older images with the same filename.
Are you running a Managed or a Referenced Library?
A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package
A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.
