When must to use WLC? And why?

I've ever used Access Points standalone (AIR-AP1242G-E-K9 || 802.11g Integrated Auto AP; RP-TNC; ETSI Cnf) and now I've to do a
new installation for a customer and this model is in End-of-Life.
I found in web the substitute is AIR-SAP1602E-E-K9, but there's a controlled model AIR-CAP1602E-E-K9. I've never used a WLC
and I'm not sure what are the benefits of using it. I think this customer is good to use a controller because is a avanced user but I've
to advise the best choice to her.
Could anyone send me a link where I can learn the difference between working with WLC or without?
And... whats is the controller for AIR-CAP1602E-E-K9?
Thanks

It makes it more easy to controll a high amount of APs in your network.
- Central management
- Easy controll of administrativ access permissions
- Easy configuration of TACACs
- Easy cofiguration of WLAN- Security
-- High efficency of time for the administrator
And maybe the same Scott told you, the WLC2504 is, as i know, delivered with an incompatible softwareversion by default.
You can see the needable WLC softwareversion on the matrix. 7.4.100.x is high enough for the 1602 AP.
But be carefull with 7.4.x.x. There is no longer support for older APs like the 1100 series APs.
Like to help, like to get helped!

I have CS6 and CC installed on my mac when I'm using CS6 and use bridge CC activates how can I set this to only work on one and not the other

If you want Bridge CS6 to open when using Photoshop CS6, you must quit Bridge CC.
Then File menu > Browse in Bridge will bring up Bridge CS6.
If Bridge CC is already open, The File > Browse in Bridge for Photoshop CS6 will use Bridge CC and Bridge CS6 will not open.
I hope that's the answer you were looking for.

Vector is not a Thread safe so where be use it and why?

Can anyone tell me
When Vector is not a Thread safe so where be use it and why?

Suppose you use a Vector<Listener> to store your list of listeners. While the Vector class is thread-safe, which means that its methods can be called without additional synchronization without risk of corrupting the Vector data structures, iterating a collection involves "check-then-act" sequences, which are at risk of failing if the collection is modified during iteration. Let's say there are three listeners in your list at the start of iteration. As you iterate through the Vector, you repeatedly call size() and get() until there are no more elements to retrieve, as in Listing 1:
Listing 1. Unsafe iteration of a Vector
Vector<Listener> v;
for (int i=0; i<v.size(); i++)
v.get(i).eventHappened(event);
But what happens if, just after you call Vector.size() for the last time, someone removes a listener from the list? Now, Vector.get() will return null (which is correct, because the state of the vector has changed since you last checked), and you will throw a NullPointerException when you try to call eventHappened(). This is an example of a check-then-act sequence -- you check to see if any more elements exist, and if so, you get the next element -- but in the presence of concurrent modification, the state could have changed since the check.
I read that at IBM sites
Thanks in advance for clearing my doubts...

Hi Smash126,
Based on the error message” Could not allocate a new page for database REPORTING' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting
autogrowth on for existing files in the filegroup”, we can know that the issue is caused by the there is no sufficient disk space in filegroup 'PRIMARY' for the ‘REPORTING’ database.
To fix this issue, we can add additional files to the filegroup by add a new file to the PRIMARY filegroup on Files page, or setting Autogrowth on for existing files in the filegroup to increase the necessary space.
The following document about Add Data or Log Files to a Database is for your reference:

If there are any other questions, please feel free to ask.
Thanks,

How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?

How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?
Hi,
I do generate XML-Files by using DBMS_XMLGEN with output by UTL_FILE
but it seems, the xml-Datafile I get on end is not really UTF-8 encoding
( f.ex. cannot verifying it correct in xmlspy )
my dbms is
NLS_CHARACTERSET          = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET     = AL16UTF16
NLS_RDBMS_VERSION     = 10.2.0.1.0
I do generate it in this matter :
declare
xmldoc CLOB;
ctx number ;
utl_file.file_type;
begin
-- generate fom xml-view :
ctx := DBMS_XMLGEN.newContext('select xml from xml_View');
DBMS_XMLGEN.setRowSetTag(ctx, null);
DBMS_XMLGEN.setRowTag(ctx, null );
DBMS_XMLGEN.SETCONVERTSPECIALCHARS(ctx,TRUE);
-- create xml-file:
xmldoc := DBMS_XMLGEN.getXML(ctx);
-- put data to host-file:
vblob_len := DBMS_LOB.getlength(xmldoc);
DBMS_LOB.READ (xmldoc, vblob_len, 1, vBuffer);
bHandle := utl_file.fopen(vPATH,vFileName,'W',32767);
UTL_FILE.put_line(bHandle, vbuffer, FALSE);
UTL_FILE.fclose(bHandle);
end ;
maybe while work UTL_FILE there is a change the encoding ?
How can this solved ?
Thank you
Norbert

Marco,
I tryed to work with dbms_xslprocessor.clob2file,
that works good,
but what is in this matter with encoding UTF-8 ?
in my understandig, the xmltyp created should be UTF8 (16),
but when open the xml-file in xmlSpy as UTF-8,
it is not well ( german caracter like Ä, Ö .. ):
my dbms is
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16
NLS_RDBMS_VERSION = 10.2.0.1.0
-- test:
create table nh_test ( s0 number, s1 varchar2(20) ) ;
insert into nh_test (select 1,'hallo' from dual );
insert into nh_test (select 2,'straße' from dual );
insert into nh_test (select 3,'mäckie' from dual );
insert into nh_test (select 4,'euro_€' from dual );
commit;
select * from nh_test ;
S0     S1
1     hallo
1     hallo
2     straße
3     mäckie
4     euro_€
declare
rc sys_refcursor;
begin
open rc FOR SELECT * FROM ( SELECT s0,s1 from nh_test );
dbms_xslprocessor.clob2file( xmltype( rc ).getclobval( ) , 'XML_EXPORT_DIR','my_xml_file.xml');
end;
( its the same when using output with DBMS_XMLDOM.WRITETOFILE )
open in xmlSpy is:
<?xml version="1.0"?>
<ROWSET>
<ROW>
<S0>1</S0>
<S1>hallo</S1>
</ROW>
<ROW>
<S0>2</S0>

Hi,
I lost my airport connection when I was using internet and when I wanted to re-reconnect to airport it gave me connection timeout error, I changed my password on router but still doesn't work. How can i fix my problem?

Hello there hastibahreini,
It sounds like you were using your Wi-Fi network from your Airport base station and the connection cut out. You have reset the password on the device but the issue persists. I would try the 3 resets outlined in the following article in order to help resolve the issue. If it persists, is the Wi-Fi connection issue happening on more than one device or computer?

What is mean by Referential Integrity? Where do we use it and Why..?

Hi All,
Can anybody tell me, What is mean by Referential Integrity? Where do we use it and Why..?
Regards,
Kiran Telkar

Dear Kiran Telkar ,
you might be knowing that generally refrential integrity is concerned with nothing but primary key and foriegn key relationship. Generally we use to check uniqueness of records.
In sap we use it during flexible updation...to check the data records of transaction data and master data.
In other words, to check before loading of data, that whether loading will be properly or not.
we will check(tick) the option in the maintainance of the
<b>infosource--> communication structure</b>
it will be better if you clearly mention your problem, if further help is needed.
hope this will help you.

HT4914 When I'm using iCloud,and I'm NOT in wifi will I need to pay a service provider for data useage?

When I'm using iCloud,and I'm NOT in wifi will I need to pay a service provider for data useage?

It's your choice. If you know that you will be away from wifi then you could download the music that you want to listen to so that it is available on your phone. If you do subscribe to Match and want to be able to access it via your carrier's network then you will also need to be an area where you get reception from your carrier.
There are also some wifi-enabled external drives that allow you to stream content to a device e.g. Seagate GoFlex Satellite

Hmmm, mine stack up over the pinned icon as you would expect (Win7Pro x64). Is there anything special about the way you're starting up Firefox? Security sandbox? Using any command-line switches?

Error when creating Recordset using CF and Postgres

I'm a complete newbie when it comes to databases and development so go easy on me.
I have created a simple database with a schema (ABC) and 2 tables (_Address, _Member) in Postgres 9.0. I have installed CF 9 in development and am creating a new application using the Construction Kit Vol 1 as my guide. I got to the point where I am to make a Recordset and keep getting an error of:
-1:ERROR: schema "ABC" does not exist
org.postgresql.util.PSQLException: ERROR: schema "ABC" does not exist
...about 20+ lines of at errors follow (can post a screenshot if they would be helpfull)...
From the Database tab I am able to browse my database just fine but I cannot create this recordset in the bindings tab. I also followed the examples in the book and using their database I am able to create a recordset just fine. CF says my data source verifies correctly. I have verified that my password is correct as well as when in the database tab of DW I can test the connection fine. I cannot edit the connecton from there but I get the same error when I try to edit on all of the databases, including the default test databases.
Any suggestions would be greatly appreciated.

Hi Loan,
In your stock transfer Purchase Order has the correct 'Shipping Point' been determined for this item - i.e. the 'Shipping Point' associated with your 0002 Storage Location?
The 'Shipping Point' determination is setup in config in <OVL2>, you can use the 'Loading Group' field in the Material Master (Sales:General Plant) tab to influence the shipping point that is automatically determined for a Material.
Assuming the Shipping Point has been determined correctly for your 0002 SLoc - then in <VL10B> you will have selected this 'Shipping Point' for your delivery creation. I also noticed that in <VL10B> on the Material tab you have the option to specify a SLoc (I'm assuming this is a source SLoc since the help doesn't clearly specify) - try entering this data too and see if you can generate your delivery.
Good luck,
Ravelle

My Mac is running very slowly especially when I am using Facebook and related products. What can I do to fix this?

Hello everyone. My Mac is running very slowly when I am using the internet, and especially when on Facebook. The little rainbow globe spins around for ages before changing pages etc. I have done several virus checks etc, but cannot find anything wrong. Sorry, but I am not tech savvy, so have difficulty with these issues.

Thanks for your reply. Well, I am not sure about the OS X version, I just gave that info from the Install DVD. I have the machine on automatic updates so I guess I am using a newer version. I know it is iMac Snow Leopard and I bought it in 2009. It is the 21.5 inch model. That is all I can tell you. I have 499GB and have used only 32GB, so it isn't a space problem.

When uploading, what are "previews" and why do they take so long?

After selecting photos from iPhoto library to upload and hitting upload all the photos were accessible in a reasonable amount of time.
However, then a message stated that "previews are uploading." I can see thumbnails and enlarge all my photos in Revel ..so what is a "Preview" file? Why do they take so long to upload? Is the Preview the same as a full-size file?
Also, of the 3,000 images I chose Revel excluded 72. (not dupes...they were separately counted). How do I know which ones were not selected? And WHY?

Richard, Thank you.
I am using a MacBook Pro, OSX 10.9.2. There are no RAW files and no xmp's. Corrupt files are possible.
I have noticed that today the "previews" finished uploading. And now the "originals" are beginning to uload. If 3,600 previews took almost 4 days to upload, i can expect 3,600 originals will take much longer. The internet speed is medium @ 1.5.
My iPhoto library has 12,000 photos and only a few videos. I don't think I will live long enough to try uploading a duplicate library via a web client at Adoberevel.com (laughing) I doubt that at this rate I'll be able to upload even half to Revel in the 1st 30 days.

When must to use WLC? And why?
