Performance with encrypted CAPWAP?

Does anyone have experience with encrypting CAPWAP tunnels on between your AP's and WLC's?
According to:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/6-0/configuration/guide/Controller60CG/c60lwap.html#wp1508163
"Encryption limits throughput at both the controller and the access point, and maximum throughput is desired for most enterprise networks."
My question is- has anyone enabled encryption and seen if there is actually degradation in throughput? We are considering enabling encryption on a couple hundred APs and dont want this extra overhead to bog things down on the controllers or APs.
Thanks

Hi Chad,
No we dont have large number of APs in our enviournment.
But my recommandation is: Enable only when you need like for mesh or office extends AP(to add security).
I will not recommand to enable on local mode APs.
As per cisco:
Encryption limits throughput at both the controller and the access point, and maximum throughput is desired for most enterprise networks.

Query Performance Is "Aggregates" the way out for me?

° the OLAP cache is architected to store query result sets and to give all users access to those result sets.
If a user executes a query, the result set for that querys request can be stored in the OLAP cache; if that same query (or a derivative) is then executed by another user, the subsequent query request can be filled by accessing the result set already stored in the OLAP cache.
In this way, a query request filled from the OLAP cache is significantly faster than queries that receive their result set from database access
° The indexes that are created in the fact table for each dimension allow you to easily find and select the data

° when you load data into the InfoCube, each request has its own request ID, which is included in the fact table in the packet dimension.
This (besides giving the possibility to manage/delete single request) increases the volume of data, and reduces performance in reporting, as the system has to aggregate with the request ID every time you execute a query. Using compressing, you can eliminate these disadvantages, and bring data from different requests together into one single request (request ID 0).
This function is critical, as the compressed data can no longer be deleted from the InfoCube using its request IDs and, logically, you must be absolutely certain that the data loaded into the InfoCube is correct.
see http://help.sap.com/saphelp_nw04/helpdata/en/ca/aa6437e7a4080ee10000009b38f842/content.htm
° by using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.

Powershell script monitor with encrypted password

I have created a powershell script based monitor in my management pack and everything is ok but I can't get my credentials work inside the script. I want to open pssession to another computer with my credentials. I have triple checked that my pssession is
working because I can access it from powershell console.
This works perfectly at local server from PSconsole:
$EncryptedPassword ="01000000d08c9ddf0115d1118c7a00c04fc297eb01000000534b2....etc...etc..."
$pw = convertto-securestring -String $EncryptedPassword
$cred = new-object System.Management.Automation.PSCredential -argumentlist "MyDOMAIN\MyACCOUNT",$pw
$s = New-PSSession -ComputerName "MyServer" -Port MyPort -Credential $cred
But when I run the same lines inside my management pack the convertto-securestring
does nothing, it just wont convert the encrypted password to secure string!
I have tried this plain text method and it works
inside my management pack, but I don't want to use it because you can see the password in plain text:
ConvertTo-SecureString -String "myPlainTextPassword" -AsPlainText -Force
This is the $error variable, so it's basically says that I don't have anything in the password secure string variable because the convertion did not work for some reason:
The argument is null. Provide a valid value for the argument, and then try running the command again. Cannot process argument transformation on parameter 'Credential'. PromptForCredential Exception calling ".ctor" with "2" argument(s):
"Cannot process argument because the value of argument "password" is null. Change the value of argument "password" to a non-null value." The system cannot find the file specified. Exception calling "SecureStringToBSTR"
with "1" argument(s): "Value cannot be null. Parameter name: s" The system cannot find the file specified. Exception calling "SecureStringToBSTR" with "1" argument(s): "Value cannot be null. Parameter name: s"
The system cannot find the file specified.
So is there some known issue with SCOM Agent / management pack when you are dealing with convertto-securestring
function with encrypted passwords?
I used these methods to encrypt the password: Technet article about encryption

I got it to work!

Performance with the new Mac Pros?

I sold my old Mac Pro (first generation) a few months ago in anticipation of the new line-up. In the meantime, I purchased a i7 iMac and 12GB of RAM. This machine is faster than my old Mac for most Aperture operations (except disk-intensive stuff that I only do occasionally).
I am ready to purchase a "real" Mac, but I'm hesitating because the improvements just don't seem that great. I have two questions:
1. Has anyone evaluated qualitative performance with the new ATI 5870 or 5770? Long ago, Aperture seemed pretty much GPU-constrained. I'm confused about whether that's the case anymore.
2. Has anyone evaluated any of the new Mac Pro chips for general day-to-day use? I'm interested in processing through my images as quickly as possible, so the actual latency to demosaic and render from the raw originals (Canon 1-series) is the most important metric. The second thing is having reasonable performance for multiple brushed-in effect bricks.
I'm mostly curious if anyone has any experience to point to whether it's worth it -- disregarding the other advantages like expandability and nicer (matte) displays.
Thanks.
Ben

Thanks for writing. Please don't mind if I pick apart your statements.
"For an extra $200 the 5870 is a no brainer." I agree on a pure cost basis that it's not a hard decision. But I have a very quiet environment, and I understand this card can make a lot of noise. To pay money, end up with a louder machine, and on top of that realize no significant benefit would be a minor disaster.
So, the more interesting question is: has anyone actually used the 5870 and can compare it to previous cards? A 16-bit 60 megapixel image won't require even .5GB of VRAM if fully tiled into it, for example, so I have no ability, a priori, to prove to myself that it will matter. I guess I'm really hoping for real-world data. Perhaps you speak from this experience, Matthew? (I can't tell.)
Background work and exporting are helpful, but not as critical for my primary daily use. I know the CPU is also used for demosaicing or at least some subset of the render pipeline, because I have two computers that demonstrate vastly different render-from-raw response times with the same graphics card. Indeed, it is this lag that would be the most valuable of all for me to reduce. I want to be able to flip through a large shoot and see each image at 100% as instantaneously as possible. On my 2.8 i7 that process takes about 1 second on average (when Aperture doesn't get confused and mysteriously stop rendering 100% images).

Performance with external display

Hello,
when I'm connecting my 19'' TFT to the MacBook the performance (with the same applications runnig) is realy bad. It tooks longer to switch between apps and if I don't use an app for some time, it can took up to 30 sec to "reactivate" the app.
Because the HD is working when I switch apps, it looks like the OS is swapping. My question: Would it help to upgrade the MacBook to 2GB ram? AFAIC the intel card uses shared memory.
Thanks for your help

How much RAM do you have? Remember that the MB does not have dedicated VRAM like some computers do and that it uses the system RAM to drive the graphics chipset.
I use my MB with the mini-DVI to DVI adapter to drive a 20" widescreen monitor without any of the problems that you describe, but I have 2GB of RAM. If you only have the stock 512MB of RAM, that may be part of what you are seeing.

Performance with LinkedList in java

Hello All,
Please suggest me any solution to further improve the performance with List.
The problem description is as follows:
I have a huge number of objects, lets say 10,000 , and need to store the objects in such a collection so that if i want to store an object at some particular index i , I get the best performance.
I suppose as I need indexed based access, using List makes the best sense as Lists are ordered.
Using LinkedList over ArrayList gives the better performance in the aforementioned context.
Is there are way I can further improve the performance of LinkedList while solving this particular problem
OR
Is there any other index based collection using that i get better performance than LinkedList?
Thanks in advance

The trouble with a LinkedList as implemented in the Java libraries is that if you want to insert at index 100, it has no option but to step through the first 100 links of the list to find the insert point. Likewise is you retrieve by index. The strength of the linked list approach is lost if you work by index and the List interface gives no other way to insert in the middle of the list. The natural interface for a linked list would include an extended Iterator with methods for insert and replace. Of course LinkedLists are fine when you insert first or last.
My guess would be that if your habitual insertion point was half way or more through the list then ArrayList would serve you better especially if you leave ample room for growth. Moving array elements up is probably not much more expensive, per element, than walking the linked list. Maybe 150% or thereabouts.
Much depends on how you retrieve, and how volatile the list is. Certainly if you are a read-mostly situation and cannot use an iterator then a LinkedList won't suit.

Be careful; post the code you're actually running.
query 1: select count(*) from TEST_DATA where trunc(fdate) = trunc(sysdate);
query 2: select count(*) from TEST_DATA where fdate between trunc(sysdate) and trunc(SYSDATE) + .99999;

My questions:
1) Why isn't the index t_indx used in Execution plan 1?To use an index, the indexed column must stand alone as one of the operands. If you had a function-based index on TRUNC (fdate), then it might be used in Query 1, because the left operand of = is TRUNC (fdate).
2) From the execution plan, I see that query 2 & 3 is better than query 1. I do not see any difference between execution plan 2 & 3. Which one is better?That depends on what you mean by "better".
If "better" means faster, you've already shown that one is about as good as the other.
Queries 2 and 3 are doing different things. Assuming the table stays the same, Query 2 may give different results every day, but the results of Query 3 will never change.
For clarity, I prefer:
WHERE fdate >= TRUNC (SYSDATE)
AND fdate < TRUNC (SYSDATE) + 1(or replace SYSDATE with a TO_DATE expression, depending on the requirements).
3) I read somewhere - "Always check the Access Predicates and Filter Predicates of Explain Plan carefully to determine which columns are contributing to a Range Scan and which columns are merely filtering the returned rows. Be sceptical if the same clause is shown in both."

Problem in using socket streams with encryption and decryption

Hi,
I am developing a client/server program with encryption and decryption at both end. While sending a message from client it should be encrypted and at the receiving end(server) it should be decrypted and vice versa.
But while doing so i got a problem if i use both encryption and decryption at both ends. But If i use only encryption at one (only outputstream) and decryption at other end(only inputstream) there is no problem.
Here is client/server pair of programs in which i am encrypting the outputstream of the socket in client side and decrypting the inputstream of the socket in server side.

**** I know that the CInput tries to read some header stuff thats why i used two threads for input and output.
Waiting for the reply.
Thank you.

Do not ever post your code unless requested to. It is very annoying.
Try testing what key is being used. Just to test this out, build a copy of your program and loop the input and outputs together. Have them print the data stream onto the screen or a text file. Compare the 1st Output and the 2nd Output and the 1st Input with the 2nd Input and then do a static test of the chipher with sample data (same data which was outputted), then do another cipher test with the ciphertext created by the first test.
Everything should match - if it does not then follow the steps below.
Case 1: IO Loops do not match
Case 2: IO Loops match, but ciphertext 1st run does not match loop
Case 3: IO Loops match, 1st ciphertext 1st run matches, but 2nd run does not
Case 4: IO Loops match, both chiphertext runs do not match anything
Case 5: Ciphertext runs do not match eachother when decrypted correctly (outside of the test program)
Problems associated with the cases above:
Case 1: Private Key is changing on either side (likely the sender - output channel)
Case 2: Public Key is changing on either side (likely the sender - output channel)
Case 3: Private Key changed on receiver - input channel
Case 4: PKI failure, causing private key and public key mismatch only after a good combination was used
Case 5: Same as Case 4

Using a ZFS volume with encryption on as the Virtual disk in a Sparc VM

Hi guys,
Working my way through understanding how virtualization works in VM for Sparc. One question I thought of deals with having encryption turned on in a ZFS volume. If I create a volume with encryption ON, and then attach that volume as the sole virtual disk in a guest domain, will the virtualization still work? Has anyone else dealt with a scenario like this? I'm about to try it now, I'll report back with my findings.

From my understanding, if you create a ZFS disk with encryption ON, mount it on Solaris, and after that present that to the VM, you should not have problems. The encryption will work between the volume and Solaris. To the guest vm, it should be transparent.

Can i partition my HD now for fcpx since i didn't do it when i downloaded it. my performance with fcpx is terrible terrible performance

When i downloaded FCPX i was told I really didn't need to partition my hard drive. But my performance with fcpx is terrible from rendering constantly to waiting for a minute after you click for it to do it. I turn off the rendring, I transcoded the media to pro res went to file and hit transcode. but still i mean it crashes, buggy, suggy and it takes hours to do anything. I have my media on a external drive but i did screw up and put some media on internal drive. iMac OSX 10.7.2 3.06 GHZ Core 2 Duo. EX HD LaCie on a 800 firewire.

Partitioning the internal drive is - imho! - completely useless for UNIX-systems such as MacOS, due to excessive usage of (hidden!) temp-files.
And, especially a too small int. HDD partition for the system will brake any app 'til a full halt.
plus, 10.7. has some issues with managing Timemachine backups when it comes to large files as video - again, if the intHDD/OS drive is too small, it gets iffy.
at last >30GBs free, only codecs and material as intended by Cupertino = no probs here (on a much smaller/older set-up).

Slow Performance with Business Rules

Hello,
Has anyone ever had slow performance with business rules? For example, I attached a calc script to a form and it ran for 20 seconds. I made an exact replica of the calc script in a business rules and it took 30 seconds to run. Also, when creating / modifying business rules in EAS it takes a long time to open or save or attach security - any ideas on things to improve this performance?
Thanks!

If you are having issues with performance of assigning access then I am sure there was patch available, it was either a HSS patch or planning patch.
Cheers

Very Slow SMB Performance with DroboShare

Hi there,
We have a big issue with a DroboShare NAS device connected to a Drobo Drive (FAT32):
If we connect to our DroboShare NAS directly via LAN, the performance with SMB is terrible. Browsing folders takes minutes until the contents (15 items) are shown, opening and saving files takes minutes.
If we connect the Drobo via USB to one of our Macs and then share it via SMB, it is fast as ****.
Problem is that we cannot leave it this way, as we only have portable macs, so if they are removed, nobody can access the Drobo.
The problem nevertheless seems to be restricted to Macs: If we connect to the DroboShare with Linux or Windows Boxes, everything is as fast as expected.
Does anyone has similar issues with weak performance and/or knows how this can improved?
Any help is greatly appreciated.
Thanks,
Simon

I just ported netatalk (AFP) over to the DroboShare.

Need help in creating a view with Encryption for hiding the code used by the multiple users

Hi,
Can anyone help me out in creating view with encryption data to hide the stored procedure logic with other users.
I have create a stored procedure with encryted view but while running this manually temporary views are getting created, therefore the problem is if there are 500 entries then 500 temp views will get created.
Any solution to aviod creating temporary views, please refer my code below
USE [etl_validation]
GO
/****** Object: StoredProcedure [dbo].[Pr_DBAccess_mod]    Script Date: 05/23/2014 12:53:22 ******/

/*SET @openquery= 'SELECT * INTO ##TestTable
                 FROM OPENROWSET(''SQLNCLI'',''server=192.168.31.176;Trusted_Connection=yes;'','''+@query+''')'
SET @openquery= 'CREATE VIEW '+@TABLENAME+@ETL_CONFIG_IDN+
                 ' WITH ENCRYPTION AS SELECT * FROM OPENROWSET(''SQLNCLI'',''SERVER='+@SERVERNAME+';TRUSTED_CONNECTION=YES;'',''SELECT * FROM '+@DATABASENAME+'.'+@HIERNAME+'.'+@TABLENAME+''')'
SELECT @openquery
END
EXECUTE sp_executesql @openquery
END

Hi aa_rif,
According to your description and code message, you execute the sp_executesql statement in your stored procedure, it indeed create many views with a tablename and ETL_CONFIG_ID named. If you need not to use these temporary views, you can delete them when
it contains the tablename in one view name.
In addition, if you want to create view with encryption in SQL Server, you can use directly the ENCRYPTION option to encrypt the T-SQL of a view in create view commands, for more information, see:
http://learnsqlserver.in/4/Create-View-With-Encryption.aspx. if not, you can descript more detail about requriements, so that more forum members can involve into the thread and help you
out.
