Correlating a flow from client to the VIP and from the VIP to the server

Hi,
we need to look at a flow from a client to a server that is traversing a VIP on the ACE. So, we pulled the sniffer traces between the client and the VIP and also between the VIP and the back-end server. How do we find the same flow on these sniffer traces?
Thanks.

Hi Greg,
If ACE is just forwarding the client request the you should see the client port and IP at the backend. If ACE is doing NAT then you can try and filter on the basis of time stamps or information in HTTP header like specific client cookie but mostly when you have different front end and back end streams then time stamps are your best option. Normally during TS taking simultaneous output of "show conn" also helps in corelating front end and backend connection. You can take connection ID and see the corresponding backend stream and vice versa
show np x me-stats "-c -vvv"--->where x is NP 1 or 2 or 3 or 4 depending upon the specific connection output in show conn.

Need to check the data flow from R/3 to BW server.

Hi BI experts,
This query is regarding need to check the data flow from R/3 to BW server.
As of now I have some set of reports which I would need to take up in BW. The requirement is to go through the list of transaction codes for reports in R/3 and find out if there are already any existing objects in BW system which I can use for these reports.
So, can u plz help me.

Depends what are your Tcode or Reports users run in R/3 and they want the same in BW.Then in BI Content we have Out of the box Delivered reports.You can activate those Load data and use it.
Gimme T-codes you have I can send you Standard reports in BI or Cube you can get these from.

Async tcp client and server. How can I determine that the client or the server is no longer available?

Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.
I thought I will get an exception if the client or the server is not available but this is not happening.

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

Sending a certificate form the client to the server... how to ?

how can I send a certificate from the client to the server trough a Java code ??

Short answer: You specify a keyStore.
Either via command line using the -Djavax.net.ssl.keyStore=keystorefile property,
or in Java code:
char[] passphrase = "password".toCharArray();
SSLContext ctx = SSLContext.getInstance("TLS", "SunJSSE");
// KeyStore for the SSL client certificate
KeyStore keyStore = KeyStore.getInstance("PKCS12");
keyStore.load(new FileInputStream("client-cert.p12"), passphrase);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("SunX509", "SunJSSE");
keyManagerFactory.init(keyStore, passphrase);
// keyStore for trusted server certs or CAs
KeyStore trustedKeyStore = KeyStore.getInstance("JKS");
trustedKeyStore.load(new FileInputStream("verisign-test-cert"), passphrase);
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("SunX509", "SunJSSE");
trustManagerFactory.init(trustedKeyStore);
ctx.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), null);
SSLSocketFactory sslSocketFactory = ctx.getSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory);
// open the http connection to the party
myConn = (HttpsURLConnection)myURL.openConnection();

Generated either client or the server

which logs can be generated either client or the server?

I must be having a déjà vu... No, wait... you have posted this before:

I have a similar chat application. When the user attempts to connect, instead of sending a simple string, the client sends a serialized object(xml string) with all relevant login and session information, this includes the user's IP address. Once the server
receives said information, depending on the type of TCP broadcast (a custom enumerated type) information from one user may be passed to a single user, or distributed to many users.
If it helps, here is the TCPBroadcast object I use. But in order for your server to understand it, you kind of have to build your server and client somewhat around it.

How to automate accept client of the server side?

Hi.....
I am a beginner of using J2ME to developing my final year project. I have some problem of using bluetooth packet. I can't accept again the client message when the server accepted before. Any one can solve my problem? How can I using the loop or timer to accept the client message without using acceptAndOpen() packet? Thank a lot.....
The sample code is here:

This question isn't logical at all. You don't execute javascript on the server. But if you want to waste time on it. .. look at Rhino http://www.mozilla.org/rhino/
Best of luck...

How is the dsame client find the server ?

Hi,
manager = SSOTokenManager.getInstance();
token = Manager.createSSOToken(new AuthPrincipal("uid=amAdmin,ou=administrators,ou=topologymanagement,o=netscaperoot"), "abcdefg123");
amConn = new AMStoreConnection(Token);
I have above code fragment in a standalone Java application. The Java client could not find the server. I could not use Httprequest to get the server infomation. I tried token.setproperty("hostname",dsame. wad.com.au);
tolen.setproperty("port",58080);
But this doesn't help.
Thanks in advance!!

Please ignore the syntex errors in above code.

Non Leopard client accessing the server

I have one machine in our office, a G5, that is not running snow leopard since it is not an intel machine. How do I configure that machine to join the server? All the other machines were done with login items in the account section, but that isn't available.

You should be able to use the Directory Utility, located in the /Applications/Utilities folder to manually bind to the Snow Leopard server.

2 Oracle Clients in the server

Guys,
we have a server which has an Oracle 8.1.7 installed. Since we developed a new .net application that requires Oracle 9iR2 Client, we have to install an Oracle 9iR2 also on the same machine. However, we are having problems executing stored procs that has an out parameter particulary with a clob datatype. I assume that the .net is still using the old oledb drivers of 8.1.7 instead of 9iR2. What should we do?

I have a somewhat similar issue. I think your assumption may be wrong though:
"However, because the Oracle Provider for OLE DB is a COM component, only one instance can be active at a time. This means that a later OLE DB installation will render the previous one inactive."

Contribute CS3 Client breaks the server XML

Well, I have found an interesting problem with the cthub XML
file that is stored in the "_mm" directory in the root folder of
your websites being administered by Contribute.
As you are no doubt aware, when at least one admin upgrades
to Contribute 4 or Contribute CS3 (aka 4.1) all the admins have to
since there are upgrades made to the XML files that control the
site. Well it appears that this upgrade makes the cthub file
non-valid XML.
Take a look at this file and look for the tag "font_use_css"
inside the "group_list_item" child node of the "group_list" node.
In a copy of the cthub file that was upgraded you will find that
this standalone tag is missing the appropriate closing slash. If
you compare this against a copy of the cthub file from before the
upgrade, assuming you made a backup, you will find that the tag is
properly closed.
Since this file is the master file with all of the role
information for the site, I wonder if this XML error is causing
unknown instability in the system somewhere.

I'm having the very same issue. Very frustrating. Support had me uninstall and reinstall. That did not wor
k, Then they had me uninstall and reinstall as a trial. That did not work. Very umimpressed with Adobe
products and support.
Anyone have a solution to this issue. I'm at the end of my rope.

Using the server to share files with the clients

Hello everybody!
I finally managed to install properly iFolder on a server, and the client on a few computers. Unfortunately, I was suprised to see there is no functionality to upload from the server to the ifolders structure.
I need to achieve this because the server I used is also used as a datacenter; I hoping to make the data available to each user directly on their own desktop using the mechanism integrated in the iFolder framework.
Obviously, I would like to avoid copying back with ssh or ftp the files to one local client, and forth to the server using iFolder.
The simplest thing would be to install a client on the server machine as well. Unfortunately, the folder monitoring function only works for graphical client, and my server does not have X installed.
So my last resort would be to connect by ssh to the server machine, then start a non graphical web browser, connect to https://localhost/ifolder/ and share each file one by one... Really time consuming and annoying!
Does someone have any suggestion?
Thanks a lot for your help!
Cheers

Hi
AFAIK if you create a common directory on the server, then use the web
admin interface to create a shared resource, then add the users.

First, thanks a lot for your quick help. I am actually deeply impressed by the speed!
Now, I don't know whether it is because I could not explain well my problem, or just because I can not understand your answer, but don't see what you're exactly suggesting me to do....
1) create a common directory: Do you mean I physically create a directory (mkdir /pathtodata/)? Or I create an new folder in ifolder using the web interface?
2) What is as "shared ressource"? I cannot find any reference to this term in the user manual. Do you just mean I share the ifolder I created in the previous step?
3) Add the users: I imagine this is the step where I share the ressource with the user.
Again, I am really sorry if my hesitations are stupid and the answer is obvious, but I read all the documentation and I cannot figure out the answer.
Thanks a lot for your help

Unable to initialize the Microsoft Exchange Information Store service because the clocks on the client and on the server machine are skewed

Each time I restart this exchange server, the Information Store and System Attendant don't start. If It try to manually start the services, I get the follow errors:
Event ID 5003:
Unable to initialize the Microsoft Exchange Information Store service because the clocks on the client and on the server machine are skewed. This may be caused by a time change either in the client or the server machine, and may require a reboot of that machine. Other than that, verify that your domain is properly configured and is currently online.
Event ID 1005:
Unexpected error The clocks on the client and server machines are skewed. ID no: 80090324 Microsoft Exchange System Attendant occurred.
The clocks on the domain controllers and the exchange server are set to the same time zones. As well, all three clocks are in sync down to the second. Any ideas on what's causing this and how to fix it?

Run this Command from the Exchange Server
Net time \\ADServerName /Set
and confirm the action,
and then you need to restart the service
Microsoft Exchange Active Directory Topology Service
and confirm you are not getting the Error 4001 in the event Viewer.
Thank you, it resolved my issue after being sweating looking for solution.
How can I prevent this from happening? I cannot restart services on each server reboot nor lose 5 years of my life!!!

MSExchangeSA and IS is not starting automatic at reboot after upgrading the server from SP1 to SP2

I am running a 2 node DAG with separate Hub & CAS servers
I have already upgraded the Hub CAS server and they are fine
Exchange running on Windows 2008 R2 SP1
All are in VM-Ware ESXi 5.0
After I upgrade the mailbox server to SP2 the SA and IS service not starting automatic after reboot
If I run "net time /set" command and then restart ADtopology server, the IS and SA starts fine
But again after reboot they do not start
Also I get the below event in the app log when the IS & SA fails to start
Log Name: Application
Source: MSExchangeIS
Date: 05/22/2012 5:15:03 AM
Event ID: 5003
Task Category: General
Level: Error
Keywords: Classic
User: N/A
Computer: server.domain.com
Description:
Unable to initialize the Information Store service because the clocks on the client and server are skewed. This may be caused by a time change either on the client or on the server, and may require a restart of that computer. Verify that your domain is correctly
configured and is currently online.
If I check the Registry for time resource it is taking from the DC
I manually compared the time between DC and Exchange and it is fine
Since the Exchange mailbox is virtual, I checked the time sync on VM-Ware tools and it is "unchecked"
Checked for group policy and do not find any specific to time sync.
Confirmed that Windows Time service is running
Suspecting a Operating system issue, tried to upgrade the other DAG
Even that node is displaying the same symptom and Issues
Tried to install RU1 on both nodes and that too did not fix the issue.
Checked with VM-Ware engineer and he said that every thing from VM-Ware end is fine
Is Anyone have come across the issue before ?

Exchange 2010: Unable to initialize the Information Store
Problem:
Unable to initialize the Information Store service because the clocks on the client and server are skewed. This may be caused by a time change either in the client or the server, and may require a reboot of that computer. Verify that
your domain is properly configured and is currently online.
Solution:
Open a cmd prompt from the Exchange Server as administrator (right mouse click on the command prompt shortcut and select “Run as Administrator”)
Run this command
Net time \\ADServerName /Set
Restart the Microsoft Exchange Active Directory Topology Service
*Important!! You have to restart the Microsoft Exchange Active Directory Topology Service or this fix will not work.. I tried just starting the Information Store service after running the command it it still failed..
This worked for me and all is well on my exchange server.
