Ensuring one singleton instance for multiple JVMs
i am creating a singleton object. But singleton is per JVM (or rather per classloader) right? But i want to ensure only one instance of my singleton even if there are multiple jvms....how can i achieve that?

Given computers A and B. Neither have any connectivity by any means to the other.
Install the application on both and run it. There is no way for either application to know about the other thus only one of the following is possible.
1. Both applications run and create an instance. Then there are two instances and thus it fails.
2 The application refuses to run. Then there are none and thus it fails
Other solutions are possible given that some reasonable requirements based on actual business driven needs are presented.

One portal instance for multiple hostnames with one of them using SSL
Hi,
Is it possible to use one Portal and Login Server instance for managing two hostnames (like www.site1.com and www.site2.com) of which one is using SSL. If yes, how do I do this? What do I need to configure?
Thanks,

One search help for multiple select-options in webdynpro abap
Hi,
I need a way to use one search help for multiple select-options fields. My scenario is :
I have a table for keeping different organizational units' values of different systems. I have pasted some sample data from this table at the end of this mail. On the screen I want to have 1 select-options filed for werks, and 1 select-options filed for vkorg. (In fact I will have more org. unit fields...) In the beginning of my application the user will select sid.
If the user selects ADS as SID, when he opens search-help for the first org. unit (werks), he will see the records with SID: ADS, VARBL = $WERKS, LANGU = SY-LANGU.
If the user selects AGT as SID, when he opens search-help for the second org. unit (vkorg), he will see the records with SID: AGT, VARBL = $VKORG, LANGU = SY-LANGU.
I have created a search-help taking SIDD, VARBL and LANGU as import parameters; used field mapping and bound this search help to my table. I have created 2 context nodes : org1 and org2 having attributes SID, VARBL, VALUE, LANGU .
I have assigned related SID, VARBL and Langu values to these attributes at runtime as I needed. That way, if I use input field and reference to the related context attributes org1-value and org2-value2 accordingly, search help works well as I want.
However, when I use select-options field , I can not bind the field to the context data. I can give reference only to ddic structure. Is there any way to reference to a context attribute? I searched for this in SDN, but could find nothing.
I think I won't be able to use this way. What do you say?
As I read from forums maybe using OVS help will be suitable for me. But I have to use one search-help for all select-options fields. Do you know how I can determine the active select-options field and pass its name (for instance "werks" ) as parameter to this OVS search help. (Also I'll pass SID and LANGU.)
MY TABLE (ZBYYT080) CONTENTS:
SID VARBL VALUE LANGU VTEXT
ADS $WERKS 1 T Werk 0001
ADS $WERKS 11 T OZYAS GIDA URETIM YERI
ADS $WERKS 5501 T BOYA GEBZE FABRİKASI
ADS $WERKS 5502 T BOYA CIGLI FABRİKASI
AGT $WERKS 2301 T KAMLI DAMIZLIK
AGT $WERKS 9601 T PANAR DENIZ URETIM YERI
ADS $VKORG 22 T AA KİMYASALLAR
ADS $VKORG 8001 T İINSAAT BOYALARI
AGT $VKORG 6500 T DAMk St.Org
AGT $VKORG 5400 T PANAR St.Org.
I wish I'm clear enough..
I will be gald if someone answers me as soon as possible...
Thanks İn advance..
MERALHi,
Your ques is how to refer to a DDIC search help to refer to selection screen parameter ?
Am I right ?
If Yes, then in the interface IF_WD_SELECT_OPTIONS
method ADD_SELECTION_FIELD, ADD_PARAMETER_FIELD etc
have importing param like I_VALUE_HELP_TYPE and I_VALUE_HELP_ID, I_VALUE_HELP_MODE, I_VALUE_HELP_STRUCTURE
etc which may help you to link your create DDIC Search help to selection screen params.
this is just a clue from my side. I haven't tried it myself.
You can go to the where used list of this method and find some sample implementations which use these params.
Hope this helps.
Regards

Is it possible to run single workflow instance for multiple item changed or created?
I have created a SharePoint Designer 2010 approval workflow and I am starting this workflow on item created and modified . Now when I am adding and updating multiple items it is starting workflow for each item but I want to start only one workflow for all items.
I think it is possible in workflow 2013 but i want to use in
workflow 2010.
Is this possible? if yes then how?Hi Resham,
From your description, my understanding is that you want to only start a workflow instance when multiple items are added or updated.
Per my knowledge, if we set workflow start on item created or modified, when we add or update multiple items, SharePoint will create a workflow instance for each item, it is unable to just create an instance for multiple items. It is same
between SharePoint 2010 workflow and SharePoint 2013 workflow.
You said it is possible in workflow 2013, do you have any references?
Thanks,
Wendy

I have one apple ID for multiple devices in my family. I'd like to keep it that way for itunes/app purchases. I would like a simple step 1, step 2, step 3 response on what I need to do to separate all other features like imessage, contacts, emails, etc.
I have been reasearching how to do this on the internet, but I haven't found an easy explanation yet. My family is going crazy over each others imessages being sent to others in the family and not being able to use FaceTime because of conflicting email addresses. I have read that if each person gets their own iCloud account, this would work. However, I need to know what to do after I set everyone up with their own iCloud account. Do I make that the default email address to be contacted or can they still use their hotmail email addresses. Any help- with easy explanation- would be much appreciated!!We do this in my family now. We have one account for purchases, so it is used to share music and apps (I think that is in Settings/iTunes & App Stores). Each iDevice has this configured.
Then, each of us has our own iCloud account that is configured under Settings/iCloud. That then allows us to have our own Mail/Contacts/Calendars/Reminders/Safari Bookmarks/Notes/Passbook/Photo Stream/Documents & Data/Find My iPhone/and Backup. That Backup piece is pretty sweet and comes in handly if you replace your iDevice. You can just restore from it.
So we all share the Apple Store account but we all have our own iCloud accounts to keep the rest seperate or things like you mentioned are a nightmare.
In answer to what iCloud does for you: http://www.apple.com/icloud/features/
Think of it as an internet based ("cloud") area for all of those items listed in my response. What you need to remember is photo stream only maintans the last 1000 pictures so don't count it as a complete backup solution for your pictures. Even though I rarely sync with a computer these days, I do still try to sync my phone with iPhoto (I have an iMac) so that I have copies of all of my pictures. 1000 may not stretch as far as it sounds.

Can I use one itunes account for multiple users and multiple devices?
The iTunes EULA, as I understand it (I'm not an attorney )for Apps is basically that one person can use an App multiple devices, or multiple people can use an App one device..so one to many or many to one, but not many to many....

One inspection lot for multiple materials of purchase order line items
Hi All,
My client requirement is one inspection lot for multiple materials of purchase order line items.
Please share your thoughts.
Thanks in advance for early reply.
Regards,
JishuI totally agree with Amol.
I don't think I would touch that development nor would I ever tell a client it could reliably be done through development.
Knowing what I know about the table structures, I don't think you could create any development for this that could use a significant amount of the existing tables and functionality. I think you'd have to create all your own Z tables and basically rebuild the functionality. Tying it back in with SAP data will be difficult.
You're even looking at all custom screens for your results recording and UD as well. And if you have follow-on functions like batch classification requirements, batch determination, COA publication, results copy functions, use of DMR and sampling procedures, physical samples, quality notifications, etc. etc.. you could be looking a whole lot of development.

One billing document for multiple deliveries which are for different PO
Hi All,
I have a scenario where i need to create one billing document for multiple deliveries.
Payer is same
Ship-to is same
PGI date different
Sales area is one
PO different
In standard SAP it will create seperate billing document for different PO
Please advice if there is a different copy routine which will combine all the POs in one billing document.Hi Mr. Bhat,
Go to VTFL --> Select the combination of your delivery type and billing type --> Double click at Item(Left side) --> Select your item category --> Click at details
In the feild "Data VBRK/VBRP" --> I think the routine assigned is 601 (Inv.split - PO Num.) --> Now change it to 3 (Single invoice)
Then try your process, Hope it helps.

Hi SAP Gurus,
In dunning i want to create one dunning letter for Multiple Customers, what necessary settings that i have to do.please help me.
Thanks in Advance.
RAVIIf it is single email address for all the customers of a sales organization, then you can maintain the email address at the sales organization level in t.code OVX5. If SPRO side change is not allowed, then you either maintain in SO10 text, or alternatively you can think about adding it in Z-table if it is easy to maintain and available in your system.
