Does BC4J need high network bandwidth ?

Hi,
Recently i've done some development with BC4J and test it out against another vendor (BEA,IBM).
Our test scenario is using 5 PC, each running some applications.
for LAN : i run 30 applications in each PC ( 5 PC x 20 applications = 100 Applications Concurrent )
for Modem 64 Kbps : i run 1 applications in each PC ( 5 PC x 1 applications = 5 Applications Concurrent )
Problem:
for LAN the result is fine, but for Modem 64 Kbps i have to increase the concurrent applications since the number of applications is still to small( 5 ),when i monitor the network usage,it seems that my application used all available bandwidth (64Kbps) at apprx.7 concurrent applications.
Questions:
is BC4J need high bandwidth ? or where should i look to tune my applications to use lower bandwidth ?
Thanks in advance,
Ricky HP

Hi Shay,
sorry for late respons..
finally we have finished the POC (Prove Of Concept) session,and comes out with one big question why bc4j require high network bandwidth.
Weblogic team is doing good, they have good performance and good usage of network.But the good news is our client want to use Oracle ADF Framework as their development tools. :)
so here i am, i have to solve about this network bandwidh usage issue.
to answer your question about architecture:
In last POC process,we developed simple client(without gui).
the bc4j components is placed in another linux machine with Oracle 10g Java Edition installed,so the communication between client and bc4j is made through RMI/JNDI,and the communication is made using dial up connection with limited bandwidth network ( 64Kbps modem)
client program is design to loop for several times,to call method in bc4j components.we calculate the time before method is called and after the method is called.
BC4J has good performance but lack in usage network bandwidth.
i've read steve muench tips and tricks for tuning,but seems didn't help a lot in limited network bandwidth environment.
Any help will be appreciated.
Sorry again for late response and thanks a lot

Does BC4J needs an Application Server?

Is it possible to use BC4J without an Application Server?

Gabriel:
If your client is HTML browser, you need an App Server (servlet container).
If your client is not HTML, e.g., JClient, you can run in the local mode. In that case, you don't need App Server.
Thanks.

Does Pages NEED a network connection?

I have chosen the option in Pages to not use iCloud, but every time I open Pages, the phone appears to be trying to access the network for some operation. Also, typing is slowed to a crawl, as if typing has to depend on network response time. What gives?

Hi,
It basically includes 3 systems, one is our ECC sender system, middle one is PI box and third one is the receiver system. Data is successfully reaching to PI system from our sender system.Now we want to forward this to our third party system from PI box.
I want to know that such sending of data requires direct connection to third party or it can be done by proxy server based connection to third party.If it is possible then what are the steps to do this?

What is needed to network 2 computers using Airport card

I know I need an airport card in my eMac, but is there any other cards that have to be in the computer? I want to network my eMac with an iMac using a DSL line. The eMac will be downstairs and the iMac will be upstairs. I'm waiting for delivery from Apple of the iMac. It has everything built in that is needed to network but my eMac doesn't. To make my eMac wireless is all I have to buy is an Airport Card and a Wireless Gateway for the iMac which is the computer connected to the DSL modem and Wireless USB adapter with connects to the eMac? What type of Airport Card do I need to buy for my eMac (model #'s etc.) It is the card that inserts above the super drive in the front of the computer. Is there any software that is needed to install Airport?

I am also doing some configuration changes (we have one Imac and two eMac's)
but one eMac does not have a airport card and is hardwired (ethernet) to the high speed cable modem then a apple airport. One Imac and the Emac with a airport card work fine, it is a bit tricky finding the correct airport card (or airport extreme card if you have a ATI graphics card (use about the mac/system profiler then click on more to see if you have a graphics card (which affects which airport card you need, there are alot of resellers on the net so you should find what you want.
If in doubt there is a free program mactracker which provides data on every mac made (available off off versiontracker.com (free site just register) it will guide
you on the type of card needed. I was quite amazed at the amount of different spec eMac's made in their relativealy short history.
Macwireless.com does sell eMac cards (for two models) but also antenna type
or flash drive appearing USB based wireless connectors that may help.
I found the mactracker program helpful (alot) as alot of web sites provide some vague info and I would hate to se you get stuck with a non returnable card.
The actual card install does not look hard (its done through the cd rom drive door.
I am not sure why we did not get a airport card for ours when we bought it.
Wish I did as it would have saved some $ (maybe) and surf time making sure I find the right one.
We did have a antenna wireless antenna for a "green" Imac (long gone) and it ran on OS9 but it was finicky when we had the airport base station upstairs
and the Imac and antenna in the basement (about 50-75 feet)
Best of luck
Hope this helps, I am not a expert, the serial number on the cd drawer will
nail down the model you have and what you need.
We have been working adding a laser printer and airport express and the two macs with cards work fine but the Emac with no card can not be set up yet. The laser printer will sure save on ink!

Very high network traffic to printer

I am seeing very high network traffic between my Mac (iMac, running Mavericks) and my printer, a Canon MP640, connected via Ethernet. This is when the printer is idle. According to Little Snitch, the traffic is on the order of about 50 kB/s! The network traffic comes from mDNSresponder, and is directed to canonmp640.local; it is using UDP port 5353, which seems to be the mDNS port (again, according to Little Snitch). The traffic of course goes away if the printer is off, but it needs to remain on because it is being used as a printer for other computers/devices around the house.
Is this amount of network traffic for an idle printer normal? Anyone has any idea how to stop it from doing that? I even captured some of that traffic using Little Snitch, but nothing that provided any insight to me...
Thanks in advance for any help or suggestion!

mDNSresponder is the Bonjour agent. Perhaps your printer is connecting as a Bonjour printer. See Disable Bonjour by turning off mDNSResponder - OS X Daily and OS X: How to disable Bonjour service advertising without .... I would also do a little Google search on "mdnsresponder." Also, you may want to contact Canon tech support.

Live A/V Broadcast How to support both High & Low bandwidth users ?

Hello there
I have been working on a requirement where I need to
broadcast live audio and video feeds
to Flash Media Server from where it gets broadcasted to our
customers. We have two types of
customers: High bandwidth and Low bandwidth.
Now could anyone please tell me what kind of scripting is
required at the server end so that
the Media server broadcasts to these two level of user groups
at same time. How do we control
the live feeds received at the Media server ? How do I
control the amount of bandwidth that at server
side based on the received feed so that I can broadcast to my
users based on their capacity ?
I tried running two separate flash application pulling the
feeds from SAME camera but that didn't
work as changing the settings (like Camera.setMode..) on one
program affects the settings on other
program(as both programs are connected to same camera/mic). I
do not want to buy two separate
cameras/mic to support both high/low bandwidth users. I would
need to do it programatically.
Could anyone please let me know your thoughts, it would be
very helpful to me and others.
Many thanks,
-Sakthik

Thanks Charles for your reply. I didn't know that FMS doesn't
support this feature. So you mean to say that there aren't any
other ways to control live feeds at server side ?
I would try your suggestion on setting the bandwidth and FPS
at client side but I am not sure how effective will it be because
the Server is going to push a high bandwidh data to a 56 Kbps
pipeline. There will be lot of data loss due to this narrow
pipeline. Do you think that applying setBandwidth and setFPS on
this narrowed data is going to be effective ? I dont think so, what
do you say ?
How exactly does this setBandwidth and setFPS works ? When
will it modify the data ? Will it modify the data after or before
receiving it at the client end ?
Please share your thoughts on this.
Many thanks,
-Sakthik

Optimize network bandwidth usage in large multi-size corporate environments

SymptomsTo maintain a high protection level, you may notice an increase in bandwidth due to the increased number of updates released per day. Policy Manager Proxy (PMP) installations are especially affected as the additional strain on the likely slower network connection that exists between the remote site hosting the PMP installation(s) and the main corporate site with Policy Manager Server (PMS). The network bandwidth usage can be especially high when computers are turn on on Monday as the update packages accumulate over the weekend.
DiagnosisBy default, the Automatic Update Server (AUS) in PMS calculates byte-level differences for the last five update packages (per update channel). In the event where computers were turned off over the weekend, client machine has missed five updates, and PMS will then download a full update package (Aquarius Windows updates can be approximately 140MB in size). When this happens, network bandwidth usage can be excessively high.
SolutionWe recommend applying the suggested changes on all PMS and PMP systems and all of the F-Secure clients behind PMP installations. This may reduce the update size from 140MB to 10MB. The suggested solution consists of three different changes, outlined below:
1. Increase the number of byte-level difference files stored by the PMS
For Windows
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open [F-Secure Installation Path]\FSAUS.PM\conf\server.cfg in Notepad.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS). In command prompt: net stop fsaua, net start fsaua, net stop fsms, net start fsms.
For Linux
To increase the number of byte-level differentials maintained by Automatic Update Server:
Open /etc/opt/f-secure/fsaus/conf/server.cfg.
Find the key num_old_versions_to_compare, change the value to 50, and save the file.
Restart Automatic Update Agent (AUA) and Automatic Update Server (AUS) daemons (root privileges required): #/etc/init.d/fspms restart
The overall disk space requirement for PMS increases. We estimate the disk consumption to increase by 10GB. Make sure the hard disk hosting the Policy Manager Server installation (Program files\F-Secure\Management Server 5\) has enough disk space.
2. Increase the cache size available on the PMP for storing files
For Windows
Note: Use the Advanced mode in Policy Manager Console (View >> Advanced mode) to edit the setting.
Go to F-Secure Policy Manager Proxy > Settings > Communication > Cache size.
The default setting is 500. Increase this to 5000 (5GB) and distribute new policies.
Verify the setting on all Policy Manager Proxy systems and adjust the settings, if needed. The setting specifies how much disk space is set aside for storing databases on the Policy Manager Proxy.
For Linux
As Policy Manager Proxy on Linux is not centrally managed, the change involves modifying a configuration file that exists on the Policy Manager Proxy system locally.
Open /etc/opt/f-secure/fspmp/conf/proxy.cfg.
Find the key max_cache_size, and change the value to 5000: max_cache_size=5000.
Restart the fspmp daemon (root privileges required): #/etc/init.d/fspmp restart
3. Adjust the F-Secure Anti-Virus client configuration using Policy Manager Console (PMC) to help prevent clients from immediately falling back to downloading updates directly from the PMS.
In case the client is unable to connect to the Policy Manager Proxy, for example due to high network traffic and multiple downloads taking place, the following setting dictates how soon the client attempts to connect directly to the Policy Manager Server to download updates.
In Policy Manager Console, go to F-secure Automatic Update Agent > Settings > Communications > Policy Manager Proxies > PMP Proxy fallback time.
Default value is zero which means fallback to PMS takes place immediately, in case where Policy Manager Proxy installation cannot be reached. To prevent this from happening, configure this setting to a higher value (suggest 7 hours).
These steps should ensure database updates are only downloaded via the PMP.

The name of my wireless network in the form of my modem router is not read from the iPhone, while the first era.Il my ipad does not read the network but I surf the internet. Why? What can I do?

Can I use this DIR-635 to extend the WiFi network of the "Belgacom" WiFi?
To answer this question correctly, a user would need to have a DIR-635 router connected by Ethernet to a Belgacom router.
If you think about it, the chances of another user who has these two same devices configured this way and also being on an Apple support forum to see your post are about zero.
The following might work, but you will not know until you try.
Configure the DIR-635 to provide a wireless network that uses the exact same wireless network name, exact same wireless security and exact same password as the Belgacom wireless router. Make sure that the DIR-635 is configured in Bridge Mode.
Can I purchase and set-up an Apple Airport Express or Apple Airport Extreme on my level 1 (the ethernet cable running from level 2 to level 1 could plug-into either of those)
The AirPort Express or AirPort Extreme would need to be configured exactly the same way as mentioned above.
(What is the difference in the 2 -- one is about twice the price of the other…)

How to calculate network bandwidth for dataguard 11.2

Hi all,
have a customer who needs to setup a new data guard environment in release 11.2.0.2. Primary site will be in Italy, standby site will be in New York.
He would like to know the network bandwidth between primary and standby site needed to obtain the maximum performance in redo transport with or without compression option.
I found a lot of threads and docs indicating some formulas but none of them explained how to:
- calculate network bandwidth on a rac system (having a single instance standby database)
- calculate network bandwidth in case of use redo transport compression
- calculate cpu consumption if using redo transport compression
Could you please give any advice?
A.M.

Hi,
customer made ma a lot of technical question just like the following:
- which are the main factors determining the 30% overhead indicated in the network bandwidth calculation
Required bandwidth = ((Redo rate bytes per sec. / 0.7) * 8) / 1,000,000 = bandwidth in Mbps
- how much bandwidth will I gain if I apply redo transport compression and why redo transport compression and why usually the gzip utility gives me 5X less and oracle compression gives me a maximum of 50-60% of compression even if it uses the same engine of zlib compression as indicated below?
Data Guard redo transport compression uses the same zlib compression engine at level 1 as gzip -1. To estimate the compression ratio you can achieve using Data Guard redo transport compression, first compress an archived redo log file with gzip:
$ gzip -1 <archive redo logfile>.arc
Then use the gzip --list option to explicitly display the compression ratio:
$ gzip --list <archive redo logfile.arc>.gz
Note: Use gzip version 1.3.3 or later. Refer to www.gzip.org for the latest information on gzip.
Could anyone give me any direction?
Thank you

Microsoft Office Outlook 2013 Synchronies, network bandwidth jammed Problem.

I have installed Microsoft Office Outlook 2013 (Standard Edition) in an about 5-6 Laptops, and I am facing issue that while synchronization is going on, my office network bandwidth is being affected. It utilises huge network bandwidth, and because
of that network gets jammed. I have configured using IMAP protocol and using my gmail account in that.
Can any one help me to resolve this issue.
Thanks in advance,
DIPAK AHIR.

Hi,
For your first question : YES network issue happen to all Laptops.
I will explain you the scenario, We are having some where about 80 machines (Including Desktops and Laptops) in our office network, all are working under same internet network. Out of this 80 Users We have 5-6 Laptop users who are using Microsoft
Office Outlook 2013 (Standard Edition). All these 5-6 Laptop Users are having different amount of mails (items) as well as folders. Once any of these user starts his / her mail client - Microsoft Office Outlook 2013, suddenly our network bandwidth gets chocked
and because of which my rest of the 80 users are not getting the Internet access. We have to ask them (Laptop user who has switched ON their Microsoft Office Outlook 2013) to close their mail client, Once Microsoft Office Outlook 2013 has been closed my network
gets stable. At first we thought that it is because of mails are getting downloaded from mail server and hence network is getting jammed, so we did another exercise that let their mails gets downloaded to their local machine and afterwords - next time when
they will start their mail client network should not be affected. But this network jammed scenario is still there, hence I ought to raise this issue.
For your information we have tried removing profile, deleted required folders and reconfigured Microsoft Office Outlook 2013 but still issue is being replicated.
Need your help for the same.
Thanks.

How to determine network bandwidth for EP 6.0 implementation

Hi
can you please guide me how to determine the network bandwith requirment for SAP EP6.0 implementation for smoother operation
Thanks & Regards
Ashutosh

Hi Ashutosh,
luckily network bandwidth is mostly not a problem as long as it is not very small, e.g. a modem dial-up 56kbps connection on client side. To make sure that the server side outgoing line is strong enough, you'd need to do some math and calculate from the expected request volume how much bandwidth you'd need. Some guidance might be taken out of the how to paper under this link:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/how to perform sap enterprise portal load testing.zip.
Check chapter 2.4 in the pdf file.
For "smooth operation" you'd need network wise not only worry about bandwidth but also about network latency times and sometimes network quality in regard to % package losses or similar. If your end users are more then 1000 miles away you usualy start seeing response time increases from latency times...
The impacts of networking on performance are many, but so are the tuning possibilities. If you have a lot of end-users accessing EP over a WAN, perhaps even over the Internet, and if they do so over long distance you might want to make EP landscape WAN tuning a dedicated task in your project.
In addition the network requirements of Portal are discussed in this paper : http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000757275&_SCENARIO=01100035870000000112&_OBJECT=011000358700003943521999E , chapter 3.5.2 Enterprise Portal.

Hello everyone,
I just updated my 3GS from iOS 5.0.0 to 5.0.1
Since the update, Itunes says that no SIM card is detected, and the iPhone says that it cannot be activated. It also obviously does not detect any network.
I tried restarting the phone several times, removing the SIM card several times, but it did not change anything, the SIM is still not detected.

My Macbook Pro does,nt seem to have any life in the battery does it need a new one

You can check the actual capcity by opening the "System Information" application in the folder "/Applications/Utilities".
Then you can select the information section "Hardware > Power" to see the information regarding the battery:
The important information is highlighted in the image above. The ratio of Charge Remaining (when fully charged) to Full Charge Capacity is a good metric of how "healthy" the battery is. The Number if cycles is another indicator. The higher the number of cycles the lower I would expect the ratio of Charge Remaining (when fully charged) to Full Charge Capacity.
