HOW TO IDENTIFY WHILE THE CONNECTION DISCONNECTED IN RUNNING APPLICATION.
AND HOW TO EXIT, WHILE THE CONNECTION IS DISCONNECTED.
THANKS IN ADVANCE
edward

WHEN YOU TRY TO USE THE CONNECTION THAT IS CLOSED, YOU'LL GET AN IOEXCEPTION. TO CHECK THIS, YOU'LL HAVE TO DO SOMETHING LIKE POLLING IF THE OTHER SIDE IS STILL LISTENING BY SENDING IT AN ACK MESSAGE AT SPECIFIC INTERVALS. IF YOU GET AN EXCEPTION, THE CONNECTION WAS CLOSED.

How can I print while the internet is disconnected?

I have Pro 8600.
How can I print while the internet is disconnected for some reason?
My internet router is unstable recently.
thanks.

Hi,
Your printer has these:
USB 2.0-compliant high speed
USB 2.0 high-speed host port
Wireless 802.11b/g/n*
Wired 802.3 network (Ethernet)
You can use USB or Ethernet connection to print. I always define USB as second printer and I can print direct.
Regards.

Remove attribute whenever the connection is disconnected

hi,
I'm working on an application that register new members and let the current members to login to there account. once the member is logged in no one can access the same account,once he is logged out by clicking LogOut everything goes ok but if for any reason the window was closed or the connection was disconnected while he is in this account he cannot access his account again because I'm using the following:
ServletContext context= getServletConfig().getServletContext();
context.setAttribute( "userName", new String("login") );
So I need to remove the above mentioned attribute whenever the connection is disconnected or the window is closed....
Any suggestions .....

How to identify whether the data extracted is direct, queued, unserialized

hi,
how to identify whether the data extraction from r/3 is direct, queued and unseralized data.
can anyone let me know abt it
regds
hari

hI,
Direct Delta: With this update mode, the extraction data is transferred with each document posting directly into the BW delta queue. In doing so, each document posting with delta extraction is posted for exactly one LUW in the respective BW delta queues.
This update method is recommended for the following general criteria:
a) A maximum of 10,000 document changes (creating, changing or deleting documents) are accrued between two delta extractions for the application in question. A (considerably) larger number of LUWs in the BW delta queue can result in terminations during extraction.
b) With a future delta initialization, you can ensure that no documents are posted from the start of the recompilation run in R/3 until all delta-init requests have been successfully posted. This applies particularly if, for example, you want to include more organizational units such as another plant or sales organization in the extraction. Stopping the posting of documents always applies to the entire client.
Queued Delta: With this update mode, the extraction data is collected for the affected application instead of being collected in an extraction queue, and can be transferred as usual with the V3 update by means of an updating collective run into the BW delta queue. In doing so, up to 10000 delta extractions of documents for an LUW are compressed for each DataSource into the BW delta queue, depending on the application.
new queued delta
This update method is recommended for the following general criteria:
a) More than 10,000 document changes (creating, changing or deleting a documents) are performed each day for the application in question.
b) In future delta initializations, you must reduce the posting-free phase to executing the recompilation run in R/3. The document postings should be included again when the delta Init requests are posted in BW. Of course, the conditions described above for the update collective run must be taken into account.
Non-serialized V3 Update:With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed. However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.
unserialized v3 update
This update method is recommended for the following general criteria:
a) Due to the design of the data targets in BW and for the particular application in question, it is irrelevant whether or not the extraction data is transferred to BW in exactly the same sequence in which the data was generated in R/3.

I am unintentionally come to delete the bluetooth connection to my heart rate monitor in my iPhone 4s. How can I restore the connection?

I am unintentionally come to delete the bluetooth connection to my heart rate monitor in my iPhone 4s. How can I restore the connection?

Thanks, but unfortunately for me the Polar H7 does not have any buttons or anything that can actively affect the pairing, it is manifest just a transmitter. Pairing can apparently only be done by finding the Polar H7 in the unit that you want to pair with (my 4s) and after my delete of the device, my iPhone 4s does not retrieve it as a Bluetooth device.

I cannot load my google calendar, how can i decrypt the connection in order to have access?

The information about this website says that the page has been encrypted because there is no authorized owner. I need access to my google calendar from work.
How can i decrypt the connection? Is there other way to fix the problem?

Restart holding down the CMD+R keys, launch Disk Utility and erase the HD, quit DU, and restore the OS. On first boot, use the Setup Assistant to do the migration. Details in Pondini's Setup New Mac guide.

I have had this same issue but thankfully fixed it. Follow he steps below:
Sync your iPhone with you iTunes therefore your info is backed up. Unplug your phone.
Go to Settings > Reset > Erase All Content and Settings
Once your phone has reset and come back on answer the question until it asks if you want to back up from itunes Click this then plug your phone in.
After everything has sync'd back to your phone everything should work fine.
Hope this helps.

How can I know the connections are pooled?

Hi. everyone.
I am wondering how I can monitor the connections are pooled.
I am using web-logic as a web server and oracle9ir2 as a
database server.
When I was deploying an application to the web-logic, I created a
connection pool.
And then, I run the application respectively(exactly two).
However, there is only one session in the "V$SESSION" dictionary.
I do not understand why there is only session in the V$SESSION, although
I run two application respectively.
In addition, how can I monitor the oracle conenctions are pooled?
Does V$SESSION have nothing to do with oracle connection pool?
Thanks in advance.
Have a good day.
Best Regards
Ho.

Dear Sabdar Syed.
Thanks for your reply.
Here is the result of v$license.
SQL> select * from v$license;
SESSIONS_MAX : 0
SESSIONS_WARNING : 0
SESSIONS_CURRENT : 6
SESSIONS_HIGHWATER : 6
USERS_MAX : 0
What does it mean, sessions_max(0), sessions_current(6), users_max(0)
I am still confused.
Could you give me a more detailed explanations?
Thanks in advance. Have a good day.

My wireless printer keeps going offline--how can I "stabilize" the connection"

my wireless printer keeps going offline--how can I "stabilize" the connection?
This question was solved.
View Solution.

Hello gerrie,
What i would do is Power cycle the printer and the router as well
-basically having them turned off for about 10-15 seconds
-and then powering back the router back on wait for all the lights to turn on completely
-and after that is back up and running i would turn the printer back on and re-establish the connection between the printer and the Wireless network
I am an HP employee.

How can I prevent "the connection has timed out" message.

Sorry, this is a duplicate. Can't determine how to delete. Mike.
Frequently takes a full minute to get to first page. Happens on IE as well as FF, also on my email client. After an hour or so, Thunderbird can no longer reach my email,with an error. To recover I have to reboot.
Occasionally "try again" button works on the "connection has timed out" message
Some tools which access the web take a long time to “update”,
is hard to recreate have not proven or disproven the firewall is a problem. Don't think WinXP firewall is on.
Tried refresh of Adobe Flash Player per suggestion in Firefox Support forum, no help.

Hello there, FloridaAce.
The following Knowledge Base article offers up some practical first steps for troubleshooting Wi-Fi connectivity issues with an iOS device:
iOS: Troubleshooting Wi-Fi networks and connections
If going through the initial recommended steps doesn't yield a resolution to your issue, you may want to run through this section as well:
Wi-Fi disconnects or signal strength is less than expected
Move closer to the Wi-Fi router (access point).
Check for sources of potential interference.
Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings
Thanks for reaching out to Apple Support Communities.
Cheers,

How to identify all the information for a given company code?

Hi,
Our company provides data migration services for SAP and other ERP applications. Our customers provide us the specifications for extractions and conversions. We use one or more 3rd party tools to extract data from legacy systems into text/Excel files. Customers use LSMW to load generated files.
We just got an unusual request. This customer wants to get ALL the data from SAP for a given company code and dump into Excel. They would do some manual editing on the data and load it into a new SAP client.
In the past, customers would be more specific in their requirements. For example, they will mention Materials, Customers, Inventory, etc. In this case, the customer simply wants ALL the data for a given company code.
Q1. Is everything in SAP related to company code, either directly or indirectly? For example, can materials be filtered by company code?
Q2. The tools that we use let us extract data from SAP using SQL-like queries. How do I identify ALL the tables that I would need for a given company code?
My feeling is the customer themselves are not clear on what they really want. Perhaps they are expecting us to guide them.
I would appreciate any thoughts that you may have.
If there is a more appropriate forum for this question, please let me know.
Thank you in advance for your help.
Regards,
Peter
