How to determine if extend TCP proxy isn't running?

I've setup a Coherence cluster using nodes Coh-A and Coh-B. I have a TCP proxy running on both the nodes on port 9098.
My application is able to the talk (i.e., both get and set) to the cluster through the TCP proxies.   All is fine when the coherence servers are up and running. I was curious to see the behavior of the system when coherence servers are down. My requirement is such that, it should have no impact on the system if coherence is down. The application should instead bypass Coherence and go the database. But this isn't happening (logs below). Is there any way to check if the coherence server is reachable (up and running) before trying to access the cache from the application code?

How to determine from PL/SQL which processes are running

Hi,
I would like to find out which processes are runing. Is there any way how to determine this directly from PL/SQL? I know I can run external C libraries, but if there is another way, that would be great.

Extend TCP Proxy vs. Client load balancing

I am unclear how proxy and client load balancing interact with respect to custom address providers. If I define my own address provider, and I do NOT set the load-balancer parameter to client in the client configuration, will the proxy still do load balancing of connections as described in http://docs.oracle.com/cd/E24290_01/coh.371/e22839/gs_configextend.htm#BEBCICDA ?
Edited by: user5179040 on Mar 23, 2012 9:43 AM

Hi,
The <load-balancer> element is only configured in the <proxy-scheme> and not at the client side. This parameter "proxy" dictates the proxy to use the specified strategy for load balancing client connections across proxies. The parameter "client" offloads the responsibility of load balancing to client across proxies or randomly select proxies.

Did (lsnrctl status) return anything else?
The subagent is (or was) Oracle lingo for the intelligent agent.
I wouldn't worry about the subagent unless you want to use some
of the advanced features of OEM.

How to ensure a Coherence Extend TCP service

Hi,
We have defined an Extend TCP service within our <caching-schemes> element as follows:
<proxy-scheme>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>5</thread-count>
<acceptor-config>
<tcp-acceptor>
<local-address>
<address>localhost</address>
<port system-property="tangosol.coherence.tcpproxy.port">6090</port>
<reusable>true</reusable>
</local-address>
<keep-alive-enabled>true</keep-alive-enabled>
<tcp-delay-enabled>true</tcp-delay-enabled>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>
</proxy-scheme>
However, we are not using com.tangosol.net.DefaultCacheServer as the entry point for our application and would prefer to continue to use our own main() method, ensuring caches as required.
Given this, I understand that the autostart element has no effect. Clients are unable to connect and no TCP listener appears to have been started.
Can you give a demonstration of how to call ensureService(.., ...) to start the proxy service? Is there any reason that you would advise us against this, e.g. instead starting DefaultCacheServer inside a separate process?
Many thanks,
James

Hi James,
In your main you can invoke DefaultCacheServer.startDaemon() method.

Dimitri

How do you configure the RTC as an Extend/TCP client vs Compute Client?

How do you choose between the Real Time Client acting as an Extend/TCP Client or a Compute Client?
Thanks,
Andrew

Hi Andrew,
I believe RT client as a Compute client means storage-disabled normal TCMP cluster node in a Grid Edition cluster, but I may be wrong.

Generic TCP proxy: how to create Access rule ?

Hi,
I have configured a Generic TCP proxy on the public address, port 6300 of our bordermanager server that points to an internal server 192.168.10.148 on port 80. I have configured the filter exceptions for port 6300.
I have also tried to create an ACL rule to give everyone on the internet access to the Generic TCP in different ways, but I'm unable to succeed. I can see in the proxy statistics, number of ACL denials increasing each time I try to connect so the problem is in the ACL rule.
The rule I think should be right but isn't working is the following:
Allow:
source: host Ip Addresses:
IP: equals any (the Internet)
Destination: Host IP addresses:
192.168.10.148 (the internal server)
Origin server port:
6300 (the port on the public interface on which the Generic TCP proxy is listening).
What am I doing wrong ?

EEWB : how to determine the business object and the extension type ?

Hi,
I ask myself how to determine the business object and the extension type to use to add new fields in a new tab of a specific transaction ? what means each business object, does that correspond to a specific transaction ?
I need to add a new tab in the BaMI business activity in transaction CRMD_ORDER just after the tab 'Actions' at header level.
Could you help me please to determine which business object and extension type I have to select during creation of the project and which business object category I have to select during creation of the extension (wizard) ?
Thanks for your help,
Marie

Marie,
In order to determine what type of transaction you are extending, you will need to look at the customizing for the transaction.
In the IMG:
Goto:
Customer Relationship Management->Transactions->Basic Settings->Define Transaction Types.
You will then choose the transaction defined that you want to extend. If you display the details of the transaction you will find an attribute called:
"Leading Transaction Category". This tells you the general context in which the transaction is used. The other item to view is the assignment of business transaction categories found in the maintenance screen.
This information general corresponds to one of the options that the EEWB will give you on the transaction type.
As far as extensions go, my recommendation is the following:
- Use CUSTOMER_H Customer Header Extensions for any new fields at the header level.
- Use CUSTOMER_I Customer Item Extensions for any new fields at the item level.
Unless you have a specific requirement to extend a segment of the transaction, I recommend placing all new fields in these segments. The CUSTOMER_H & CUSTOMER_I segments are considered "standard" segments, that are already built into all the necessary API structures.
Let me know if you have any further questions.
Good luck,
Stephen

Sorry,
     I noticed that the above error occurs for version 3.1.1 (& not for 3.2) as previously
     specified in previous message (above). My apologies.
     As a follow-up, i've now installed 3.2 jars on my environment & i noticed that the
     above error doesnt occur for this version. The cache server seems to be coming
     up fine now (with the appropriate TCP/IP configuration tag in the xml).
     But when i try to run my client application (which attempts to connect to this
     remote cache server), it throws an InvocationTargetException error (full exception
     below).
     The error indicates that i'm missing some elements in the XML configuration.

How to determine max netstreams before failure

Hi
Everything on Adobe's website is listed as "unlimited" and scalable but I would like to know approximate actual numbers to estimate server hardware required
I can't find out how to determine how many live audio/video netstreams per instance, specifically
1) How many broadcasters per instance?
2) How many subscribers/viewers per broadcast?
3) Does seperate application/instance provide better performance?
I understand the exact number is based on the publish settings so everyone's setup is different, but is it just bandwidth consideration?
Is there any server side functions and/or metrics besides general OS cpu/ram stats?

• How do I determine how many songs will fit on a CD?
Already answered by others.
• I heard that the LAME encoder is the best out there, is there an easy way to use that encoder to convert AAC files?
I don't think LAME is part of itunes. You need to find a different encoder. I think Max CDripper uses LAME. It's pretty common in other encoding tools so you need to search for one that you like and at a price you like.
• Can I use the LAME encoder to convert the files and then use those files in iTunes instead of using iTunes to convert them?
Yes. Understand though that nothing will convert iTunes AAC format DRM protected files except iTunes and then only to audio CD.
• I have a play list I want to burn to an MP3 CD for the car. The playlist is composed of songs with both AAC and MP3 formats. Is there an easy way to convert an then use the AAC files for this playlist?
iTunes will do this, or other audio encoders. The DRM limitation still applies, even to iTunes.
Is there a high quality way of recording streamed songs along with the title/artist info?
It depends upon the source. Different sources stream different ways, so what works with one will not always work with another. The one exception is something that captures any audio output from your computer. That doesn't capture with artist and song information, just any sound that happens to be coming from your computer. If it isn't easy to do it is probably because the people streaming the music really don't want to you do it, probably because of licensing, in which case the Terms of Use of this website don't let us discuss how to do it.

New parameter "timeout tcp-proxy-reassembly" in ASA 8.2

I couldn't find much in the config guide or web site for this. Can someone tell me which situations this would come into play? Here is the CLI help:
"Configure idle timeout after which buffered packets waiting for reassembly in tcp-proxy are dropped"

Hi.
I've had a very interesting discussion with a TAC engineer about this command.
The engineer mentions that, with this command, ASA behaves in the following way:
When the ASA receive a fragmented data, it puts the fragments in the buffer to be able to reassemble it and then sent it. When the buffer exceed the limit, the ASA start dropping the reassemble packets so the reason for the packet drop is always the buffer limit exceed . by using the command “tcp-proxy-reassembly”, the ASA wait for an idle time which is determined by this command, the reason why we need this idle time is that the ASA after dropping the fragmented packet still keeps the connection in the conn table open waiting to reassemble the fragments and send it , but this will not happen as the fragment was dropped , so this will keep the connection in the conn table and exhaust the ASA memory by a lot of connections that are not really used. After dropping the fragment the ASA waits for the timeout specified by the tcp-proxy-reassembly to delete the connection from the connection table.
So in summary the ASA uses this command not to delete the fragment after the timeout , it uses this command to delete the connection after the drop of the fragment (which is caused by the buffer limit) with the time.
So keep in mind when you use it.
Best regards,
Ernesto.

How to determine one class is a dynamic one or not?

hello,i got a simple question,like the title says.
how to determine one class is a dynamic one or not?
finally,i got an indirect solution.
package {
public dynamic class MyClass extends MySuperClass
public function MyClass()
super();
this.isDynamic=true;
this is a simple dynamic class,i defined a varible
directly,it is ok with dynamic class though i didn't declare it.
then in another class(parent class of this dynamic
class),where i try to determine the instance of this dynamic class
is a dynamic one or not.
i will use one function "checkIsDynamic" to check that
varible is exsit or not.then it will help me to determine what i
want know.
protected function checkIsDynamic():Boolean
try{this["isDynamic"]}
catch(er)
return false;
return true;
if another child class of MySuperClass didn't defined this
property,i can affirm it is not a dynamic class,or vice versa
this function also can be expanded to another one:
protected function checkProperty(prop:String):Boolean
try{this[prop]}
catch(er)
return false;
return true;
it is an useful solution,defined in parent class,and to check
the property is exist or not in child class.

try adding a property to a class instance.

Anyone know how to determine Macbook Air screen tech? Causing migraines

Hi There,
Last year, I expereinced a lot of mild migraines which I've traced back to a new Macbook Air.
At first I had no idea of the cause (diet, stress etc) but have noticed that my eyes feel uncomfortable looking at the screen of my Macbook Air (I don't have this issue with my Dell monitor).
My eyes don't hurt per se, but I can detect a sublte jittering with the screen - which can turn into a migraine.
After doing a bit of research, it seems like most (but not all) LCD and LED LCD displays use something called pulse-width modulation to control brightness but after calling Apple support, they told me my MBA doesn't use this technology.
Does anyone know how to determine the underlaying technology in Apple displays so I can research the cauase of my headaches? I found a good Ukranian website (in english) that explained pulse-width modulation but it didn't really talk about other technologies.
Any pointers in the right direction would be much appreciated.
Cheers
Ben
