Can we use single DB Adapter for multiple tables

Hi,
I have 3 tables. ONE is the Master table and other 2 tables having Primary and foreign key relationships with the Master Table.
Data is enter in the Tables 2 & 3 (based on Master Table Primary key)
I have to use a DB Adapter in BPEL Process which will be in Transaction (what type of Transaction is Best in such a Scenario).
- How do i implement it in BPEL.
- Can i use a Single DB Adapter for Multiple Tables ? (*Views* should not be created for tables 1, 2 & 3),
as we want to avoid using multiple DB Adapters, as in future Tables may increase or decrease...
- while in Transaction if Table 2 fails in Inserting / Updating, it should roll back on error and also if Table 3 fails in Inserting / Updating, it should roll back table 2 and Table 3.
- how access to concurrent users is maintained / managed in such a scenarios.
But everything should be done using Single DB Adapter without creating a separate view.
Is this Possible in BPEL..
If not, How do we design, Implementation such a BPEL Process in Transaction with a best in Performance (both BPEL Process & DB Resources)
thanks in advance
thanks & regards,
anvv sharma

Hi,
Thanks for your quick response.
I have few quires.
If we use PL/SQL, how do we implement transaction and Exception Handling appropriately based on the Error / Exception in BPEL.
If the Table 2 or Table 3 gives out Error / Exception, i have to handle it separately and intimate accordingly.
Suppose, if Table 2 got Error / Exception - Error Handling would be 'Roll back due to error in Table2'
Thanks & regads,

Can I use one itunes account for multiple users and multiple devices

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....

Can I use the same adapter for my ipad mini w/ retina display as I use for my iphone 4S?

I have an iPad mini with retina display and an iPhone 4S. Have both the small and large adapters (5W and 12W I believe) that came with the two products. I am traveling abroad and want to know if I can just use the smaller adapter (little cube-shaped one, 5W) for both the ipad and the iphone. OR, can I forgo taking the Apple adapters that were supplied, and instead use one of the travel adapters that has two 2.1-Amp USB ports?

You can use the 5W to charge the iPhone, but if it charges the iPad Mini Retina, it will be slow, so you would have to turn it off and let it sit forever to get charged. If you were going to take just one, take the 12 W on as you can use it to charge both devices without issue.
I would recommend getting the Apple travel adapters if you are going abroad. The 12W adapter should have a duck head you can pop off and put the international adaptation on there. http://store.apple.com/us/product/MB974ZM/B/apple-world-travel-adapter-kit

Using the NotificationService adapter for multiple recipients

Greetings,
We have a process that's used to send email messages using the NotificationService adapter.
Currently this process works when all recipients listed have valid mailboxes. However, if any one of the addresses is (for example the address points to a non-existant mailbox) not valid, the message is not sent.
Here is the xml from the audit trail illustrating this type of message

Now, in this case the first address (wharrell@workflowmail) is valid. The second address (vmedee@workflowmail) is not. With this list of recipients the message does not get delivered at all.
However, if I use only valid addresses which point to existing mailboxes, the message is delivered perfectly. I've tried using the Cc instead of the To and get the same results. I've been looking for a way to view the actual chat that's being used by the NotificationService adapter (the BPEL server's logging mode is on DEBUG) and am not having any luck. I've also considered trying to use multiple To or Cc elements in the BPEL adapter call but the XSD strictly specifies a MaxOccurs of 1 for both of these. Is there something I'm missing here?

Yes, It seems to be an internal, unpublished bug. Anyway, you can give reference of this thread and Bhagat Nainani for filing the backport SR.

HCM Processes and Forms : Using single Form Scenario for Multiple Countries

Hi ,
I have a requirement to design a HCM P&F form ( Single Process, Single Form Scenario ) to support multiple countries. Form fields should be visible/invisible based on the country ( derived from the login Manager). please help me with the following questions.
1. Is it right way to enable/disable the fields in the same form scenario for multiple countries ( Approx. 20-25 countries)
2. Is there any limitation to no. of fields on the form? does the form performs well with multiple dynamic conditions?
3. If yes, what is the best way to do this? through Java Script / Back end Generic Service?
Thanks in Advance,
VR.

Hi VR,
1. Is it right way to enable/disable the fields in the same form scenario for multiple countries ( Approx. 20-25 countries)
-You can use same form scenario or process for multiple countries if you are using fields based on international structure HCMT_BSP_PA_XX_R*. If you intend to use country specific fields then you may like to use different form scenario for different countries.
2. Is there any limitation to no. of fields on the form? does the form performs well with multiple dynamic conditions?
- As such there is no limiation for the fields.Yes, form performs well with multiple rule configurations.
3. If yes, what is the best way to do this? through Java Script / Back end Generic Service?
I interpret you would like to derive & show fields based on same backend logic, in that case you should generic service.
If you want to show fields based on manager's logon then you should also use authorization BAdi.

Pooja

How to use single web form for multiple secure zone signup?

I have multiple secure zones in my website. I want to sell membership of secure zones to users of my website. I want, users signup for multiple secure zone of their choice and submit payment. Is it possible if can you please explain a bit or refer me to an doc about it.
Thanks a lot for your time,

I realize this isn't likely, but do you know of a way to allow the user to select the secure zone to be registered (e.g. from a list of multiple secure zones or entering ID of one sz into a text input) from within a single web form? I wonder if this can be passed in through a parameter in the action URL or through a special system field.
Thanks

SSL Certificate for cn=abc.com considering abc.com as our major domain. now we have servers in this domain like www.abc.com, a.abc.com , b.abc.com etc. we installed the verisign certificate and configured ACE-20 accordingly for ssl-proxy and we will use same certificate gerated for abc.com for all servers like www.abc.com , a.abc.com , b.abc.com etc. Now when we are trying to access https//www..abc.com or https://a.abc.com through mozilla , we are able to access the service but we are getting this message in certfucate status " you are connected to abc.com which is run by unknown "
And the same message when trying to access https://www.abc.com from Google Chrome.
"This is probably not the site you are looking for! You attempted to reach www.abc.com, but instead you actually reached a server identifying itself as abc.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of adgate.kfu.edu.sa. You should not proceed"
so i know as this certficate is for cn=abc.com that is why we are getting such errors/status in ssl certficate.
Now my question is
1. Is is possible to remove above errors doing some ssl configuration on ACE?
2. OR we have to go for VerisgnWildcard Secure Site Pro Certificate for CSR generated uisng cn =abc.com to be installed on ACE and will be used for all servers like www.abc.com , a.abc.com etc..
Thanks
Waliullah

If you want to use the same VIP and port number for multiple FQDNs, then you will need to get a wildcard certificate. Currently, if you enter www.abc.com in your browser, that is what the browser expects to see in the certificate. And right now it won't beause your certificate is for abc.com. You need a wildcard cert that will be for something like *.abc.com.
Hope this helps,

How can I use single hard drive for both Mac OS and Windows without changing the formats and reformatting?

I have a windows PC and a Macbook Air and a 1TB external hard drive. They said in order to transfer large files into the hard drive you have to change the format of your hard drive (which would be from MS-DOS to Mac Os extended) so how can I use my external hard drive on my windows PC without reformatting its files? Please heeeelp

Natively Windows can read and write to NTFS, FAT32, and exFAT while the Mac can read and write to FAT32, exFAT, and MacOS Extended.
Option 1: You can purchase driver software for Windows to allow it to read and write Mac's MacOS Extended or you can purchase a driver to allow the Mac to read and write to NTFS.
Option 2: you can format the hard drive for exFAT and use it with both Windows and the Mac without purchasing any special drivers. (Obviously the 4GB file size limit is why you don't want to use FAT32)

Structure for Receiver Jdbc adapter for multiple tables

Hi,
For Receiver JDBC adapter,Standard structure
structure as
Statement
   Tablename(TABLE1)
        Action
        Access
Can i make a structure like
Statement
     Tablename(TABLE1)
        Action
        Access
            fields....
     Tablename(TABLE2)
        Action
        Access
            fields......
As i am using tables and I want to insert or update both of them or one based on some conditions.
Will Insert be possible in single Statement or I have to create separate statements for each table. Can you please help me on this?
Thanks in advance
Best Regards,
Harleen Kaur Chadha

Hi Harleen,
        As already said by Dharanveer, all that you need to do is replicate the Statement level, so, istead of using this structure:
Statement
Tablename(TABLE1)
   Action
   Access
     fields....
Tablename(TABLE2)
   Action
   Access
     fields......
        You will construct something like this:
Statement1
Tablename(TABLE1)
   Action
   Access
     fields....
Statement2
Tablename(TABLE2)
   Action
   Access
     fields......
       And this structure will be created in a single Data Type, that will be used to create a single Message Type, that you will use in your Message Mapping, and, the 2(or more tables that you need to manipulate) will be inserted/updated without problems using this approach.
       Thank you, and best regards,
       Wilson

Single row editing for multiple tables in a single page

Hi!
I have split a table with many many columns into more tables with a lower number of columns. There is an ID column (sequence generated) that is Primary Key common for all tables. Obviously, the relationship between these tables is 1 to 1, so its not about having to build master-detail pages.
What I need now is to edit all these tables in a single page: one single row from each table. The Automated Row Fetch & Automatic Row Processing (DML) processes used for the old table must be replaced by something else.
Is there a way to use in a single page more pairs of such processes for more tables?
I want to avoid manually writing processes with lot of PL/SQL code to handle row fetch & update.
Keep in mind that the page will have an ID item that can be used to identify unique rows in all my tables.
Thanks,
Sorin

I have split a table with many many columns into more tables with a lower number of columns
IMHO that is a very bad idea. There is nothing wrong with having many columns in a table. If you would like to split them to better "categorize" them, just create views on the table and expose different subsets of the columns.
I want to avoid manually writing processes with lot of PL/SQL code to handle row fetch & update.
That is unavoidable given how you have designed the underlying tables.
You could try creating a view that joins all the tables by the PK and creating a form based on that view. Then write a INSTEAD OF trigger on the view that "doles out" the DML on the view to each of the underlying tables.

Use single sign on for multiple portal domains

Is it possible for a user to sign on once to a domain, and then be able to access other domains. What I'm trying to do is have one user registration page/login page, but use different portal server domains to present different sites, while at the same time having a type of single sign on, once a user has entered his credentials. Thus my registration process will create a new ldap user in an external directory, and i can then just point all the different domains to that External Ldap directory.

I wouldn't recommend this because it would affect performance plus there are potential other issues like conflict that you would run into ..
Everytime a user logs into a new session is created for him and this means a user might have multiple sessions on the server. The cookie that is also set is dependent on per portal domain so it might not work ..
An alternative approach might be to have multiple roles and then customize the role for different views. You can modify the membership code in such a way that based on certain criteria you can assign him to a particular role, equivalent to your domain. However the problem could be if you want to provide delegated admin, currently the delegated admin is only at a domain level.

Using single iTunes library for multiple computers

With the new Airport Disk utility, can I attach an external hard drive with my iTunes library and have multiple computers point to that library as the library for each?

just to clarify...
Use ONE computer and ONE COMPUTER ONLY for purchasing / adding new content to the 'master' iTunes library area. Use ANY OTHER COMPUTER that's looking at that 'master' iTunes library for reading (playing back).
Yes. If you can enforce it by "persuasion", not software
Would there be a conflict if someone rates songs from other computers etc?
Yes. If they both rate at the same time.

Can I use a Time Capsule for multiple computers?

Hello,
after reading various posts on this forum I am now more more confused than ever : bear in mind that my understanding of computing stuff is quite ... limited, so I apologize if this question seems senseless.
I have several small capacity external hard drives which I uses for back ups and moving files between my computers (1 desktop (2.16 GHw Intel Core 2 Duo: Mac OSX 10.6.5), 2 laptops) but the result is a ton of confusion and multiple files everywhere. I was therefore thinking of getting a Time Capsule 2T which I would use as :
- a unique external back up machine for all my computers (without adding any other external drives)
- a wifi modem-router
Before investing that much money, can anyone tell me if the Time Capsule is indeed appropriate for the above uses, particularly being able to program all 3 machines to wirelessly back themselves up on the scheduled basis.
When I started seeing questions about adding USB driven external hardrives It made me wonder if i had gotten the purpose of the TC all wrong.
Thank you for your patience!:=)

Yes, that's exactly what it was designed for.
You can put other data on a Time Capsule, besides backups, but that will cause some conflicts, sooner or later. See #Q3 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum).
When I started seeing questions about adding USB driven external hardrives It made me wonder if i had gotten the purpose of the TC all wrong.
You can do that as well.
One purpose is, if the TC isn't large enough to back up all your Macs, you can back some up to the TC's internal HD, others to the USB drive. It varies widely depending on how you use your Mac, but a "rule of thumb" is, TM needs 2-3 times the space of the data it's backing-up, to be able to keep a reasonable "depth" of old backups for you.
Another is, if you want other data available over the network, you can put it on the USB drive to avoid the hassles in #Q3. And, since you can partition the USB drive (unlike the internal), you could use one partition for backups, another for other data.
|
There is an alternative, however, that you might find more attractive (and less expensive), since you do have a desktop Mac, and I assume you already have a wireless router.
That's to connect one or more external HDs directly to the desktop Mac, and back it up directly to that drive (or a dedicated partition on it).
Then back up the laptops over your network to a different partition on the same drive, or a different drive, via sharing. See #22 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
For moving files around, you could continue to use a small external HD, or use sharing over your network.

Thanks in advance.HTTP is a request/response protocol. You can't do what you're suggesting without "pushing" what you type to all the other users. That's not the way HTTP works. Maybe an applet and servlet.
