Can we use BLOB instead of LONG RAW in JMSStore

(Oracle 9i, Weblogic 8.1.2)
          We are putting in place a Dataguard environment (or standby database). In such environment, prod data is copied to another database in 'pseudo' real time. Unfortunately some 'old' datatypes are not supported by Dataguard. In JMS tables %JMSSTORE, the field RECORD is defined as LONG RAW and LONG RAW is one of the unsupported datatypes.
          Can we alter those tables in order to use BLOB instead of LONG RAW ?
          Regards,

          Not supported in 8.1. A supported Oracle BLOB capability will be
          available in the next release. I can think of two
          possible work-arounds:
          (1) The following might work, but is not currently supported by
          BEA: Manually create the table with a BLOB type and use
          an Oracle OCI or BEA type IV driver. Definitely do NOT use
          an Oracle thin driver, as data corruption may result.
          (2) I recall that another customer had a replication product
          they were able to get working with LONG RAW by modifying
          the table definition so that the table's handle index was a primary key.
          I do not remember the name of the product.
          (The latter modification is supported for certain releases
          now - but I think this usage must be confirmed with customer support.)

HT5132 can i use iCloud instead of MobileMe?

can i use iCloud instead of MobileMe?

iCloud can be used to sync your documents between iCloud-ready applications to your mobile devices, but you cannot use it to host web galleries. For this you will need to find a different host, for example the ftp-site of your internet provider. Export your web galleries to your hard drive and upload them to your new web host using ftp (I use Cyber Duck for this).
See Roger Wilmut's page (the last line on the page addresses links to photo galleries):
Migrating from Mobile Me:
http://www.wilmut.webspace.virginmedia.com/notes/migrate/frommobileme3.html
And if you need a replacement for your iDisk, see this user tip by Winston Churchill:
Winston Churchill: Using iCloud as an iDisk:
https://discussions.apple.com/docs/DOC-2711
If you create your web pages with iWeb, you can still use the iWeb application, but you need to patch it a little, because iWeb references icons (arrows) on MobileMe, that may not longer exist: See this guide by Old Toad and Roddy, on how to do this:
Modify the iWeb Application: http://oldtoadstutorials.net/No.26.html

Can I use speakers instead of headphones with my iPod shuffle?

How can I use speakers instead of headphones or earbuds with my iPod Shuffle?

Yes, as long as they are self-powered (don't need an amplifier) and connect using the same type of standard "mini-stereo" connector that is on headphones.

HT2534 can you use paypal instead of credit card for iTunes

just got an Ipad & am trying to download apps but can't as I need to give credit card details. Can you use paypal instead of credit card?

Sad but true, I've tried to pay for iTunes Match with my credit and couldn't because it's a subscription service, regardless the credit amount I have. The system ask me to pay with my credit card too.
How are Family Sharing purchases billed?
When you initiate a new purchase, it will be billed directly to the family organizer's account, unless you have gift or store credit. First, your store credit will be used to pay the partial or total bill. The remainder will bill to the family organizer. iTunes Store credit on your account isn't shared with other family members. So if the family organizer has a $50 credit on their account and another family member initiates a purchase, it won't deduct from the organizer's iTunes Store credit, but will bill the organizer's credit or debit card.

PAYMENTS, TAXES, AND REFUND POLICY
The Mac App Store, App Store and iBookstore services (the "Stores") accept credit cards issued by banks in Qatar or Content Codes as forms of payment.
To use the iTunes Store in a country you need a credit card (or other card type if acceptable in a country) issued in that country, billed to an address in that country, and also be physically present in that country when using the store.

Can we use EDID4 instead of EDIDD for generating IDOC

Hi Abap-Experts,
                       My question is can we use EDID4 instead of EDIDD for generating IDOC. I have declared internal table for idoc data using EDIDD...but can i use instead EDID4 for the same as well as in FM('MASTER_IDOC_DISTRIBUTE'). I have tried to use but it was giving me runtime error
   DATA : ls_edidd TYPE edidd .
DATA : it_edidd TYPE TABLE OF edidd .
LOOP AT it_cust INTO wa_cust .
    lv_segnum = lv_segnum + 1 .
    ls_edidd-segnum = lv_segnum .
    ls_edidd-segnam = 'Z1ZZ_CUST' .
    ls_edidd-hlevel = '1' .
    ls_edidd-sdata = wa_cust .
CALL FUNCTION 'MASTER_IDOC_DISTRIBUTE'
    EXPORTING
      master_idoc_control                  = ls_edidc

Thanks in advance,

Hi Alexander,
         I am not getting any error when i try EDIDD for generating IDOC..but if i try EDID4........it does give me error message.
           so please tell me what is the solution for this.

BLOB vs. LONG RAW - size restrictions?

In the Oracle Lite 10g release notes, it states...
1.3.1 BLOB Support in the Oracle Lite Database
Most of the data is stored in the Oracle Lite database file with an ODB extension; any BLOB objects—either binary or character—and the indexes are stored in a file with an OBS extension.
Because BLOB data and indexes are stored in an OBS file, there is no limit for BLOB data or indexes. The limitation for BLOB data and indexes is the space limitations of the operating system or 16 terabytes. There still exists a 4 GB limitation for the ODB file; however, this is not as much of an issue now that BLOB data can be stored in the OBS files.
I have an application that stores "blobs" in a table using the LONG RAW data type. Is the data stored in columns of type LONG RAW stored in the ODB file (which is limited to 4 GB) or the OBS file?
Thanks!
Kelly

Long columns are limited to 2Gb lenght and are stored inline.

Can we use BLOB fields (that store images) in Crystal Report ?

I'm developing with ASP.NET, VS.NET 2003.
Using Crystal Report for VS.NET
DataBase: Oracle 10g
I store a BLOB field in a table. This field store images, like jpg files.
The Stored Procedure that I use to fill the report is:
OPEN MyCursor FOR
SELECT MyId , MyImg
FROM MyTable
MyImg is BLOB field
However, when I try to use the stored procedure in Crystal Report at design mode, any field can be displayed and then drag and drop to the report, but MyImg is not possible.
There is an error message:
Details: ADO Error Code: 0x80004005
Source: Microsoft OLE DB Provider for Oracle
Description: Data type is not supported
I'm afraid that is not so easy for me to change DB connector drivers.
My question is:
- Is it possible to use BLOB fields in Cyrstal Reports?
- Or should I convert them previously to something, so they can be displayed in Crystal Report at desing mode ?
- If I should change DB connector drivers, which one should I use and from where should I download it and then install it in my Web Server?
Thank you very much!

Hi,
I dont know much at all about CR, but I do know Microsoft's OLEDB Provider for Oracle doesnt support Blob datatype.. http://support.microsoft.com/kb/q244661/
Oracle's OLEDB provider does though, you can get it as part of the ODAC download on OTN.
Hope that helps,

Can I use a G4 to get raw video footage to a no-firewire aluminum MacBook?

Hi -
I recently purchased a new aluminum MacBook 2.4Ghz and was shocked to discover the lack of a firewire port. Ok, I should have read the specs more closely before ordering, but I never would have imagined this port being removed (other than from the specialized MacBook Air). As others on this board have said, what were they thinking?!
So I have some questions about downloading raw video footage from a firewire camcorder (forgive any ignorance on my part, I'm new to camcorders and digital movie editing--I've never used iMovie). My goal is basically editing home movies.
I have an old G4 tower (1.5Ghz, 1GB RAM). I also have an external firewire/USB drive. The tower will not run iMovie '08 because the processor is too slow. The iLife 08 disc refuses to even load iMovie on this machine.
I haven't purchased a camcorder yet. I spent a lot of time researching affordable camcorders and had settled on a well-reviewed Canon miniDV, which of course, is firewire. This camera does not come with any software.
Would it work to connect the camera to my G4 via firewire, download the raw footage to my external drive connected to the G4, then move the external drive over to the MacBook, connect it to the MacBook via USB, then import the raw footage to iMovie for editing? I realize the copying over USB would be very slow. I assume I need some type of software for downloading the raw footage to the G4. Since iMovie won't run and the camera has no software, is there some type of utility or shareware that lets you capture raw footage?
Is there a better way I can use my G4 to get raw footage from a firewire camera, and then on to my MacBook? Or will this work at all?
I see that there are a few USB camcorders out there, but they seem to be expensive or don't receive very good reviews, so I'd like to go with the firewire Canon.
Thanks very much for the help with this frustrating issue

Well, never mind. I'm returning the MacBook and buying a previous generation MacBook Pro, which ends up being about $200 more.
Solves my problem, but many folks can't afford the Pro. I'll be commenting at Apple customer feedback about the lack of firewire on the new MacBook.
Thanks for reading the post.

What can i use now instead of iweb?

I know Apple did away with iweb some time ago, but what can I use now to create a simple website using mac templates?

Apple have not 'Done away with iWeb' as you put it. They are no longer supporting it and no longer upgrading it, but this DOES NOT mean that you can't still use it to create websites with.
Apple stopped supporting it sometime ago now, but it is an application like any other that you have and if you have it on your Mac, then you can still use it - it works with both Lion and Mountain Lion and if you want it you can still get it, but you'll have to purchase it from Amazon as part of either the iLife 11 or iLife 09 boxed set.
If you really want to use other software, which you don't need to take a look at RapidWeaver, Sandvox, Freeway Express and Pro 6, Flux 4 and Quick n' Easy Website Builder. Most, if not all of these have free month long trials where you can download and try before you buy.
As well as these, you have other options such as the online web site builders such as http://www.wix.com or http://www.weebly.com, or the CMS's (Content Management Systems) that you can install directly on your host/server and include http://drupal.org and http://joomla.org amongst others.
Rage software are also producing their own version of iWeb called EasyWeb - however, all first reports would seem to suggest that you won't be able to purchase this software on its own when it is released - it will initially be tied to Rage web hosting, so you would need to purchase this first to be able to use EasyWeb.
However, if you still have iWeb then use it for as long as it works and don't look elsewhere. Just because iWeb is no longer sold or supported by Apple does not mean that you can't still use it - you most certainly can.

Can I use JMS instead of multithreaded approach

Hi,
I am having a typical problem where the XML data coming through sockets using TCP/IP needs to be read and perform some action.
The code I have uses two classes to do this, each of them extending the Thread class, and invokes the individual run() method. In the run() method the second class's constructor is called which in turn invokes its own run() method. In the second run() method a handler method is invoked which does the required function. The dedicated threading approach is required in my application but my question is:
1. Instead of achieving the handling using threading, which seems to be a bit complex, can I write a JMS listener and queue the XML messages in a Oracle database. ( I am using Oracle 9i (Advance Queue can be used)).
2. Will using JMS will increase the overall performance any way?
PLease help!!
regards
Kaushik

The JMS does the threading for you. This would potentially make your application simpler but you still need a thread(s) at the end of the day in the same way.
The JMS is a more comprehensive package which hides much of the work for you. It also does alot of work which is not needed. For this reason I would expect JMS to be slower than a well written custom implementation. However, typically JMS is fast enough and much more maintainable, easily reconfigured etc. etc. and CV++ :)
My guess is that most of your work is in decoding your XML data or somewhere you don't expect.
If you want it to go faster I would suggest getting a profiler e.g. JProfiler on demo license and do some performance tests. You will probilbly find there a few simple things you can do to improve performance.
I would not concider the kind of migration you suggest until you know expectly what the problem is. You can waste alot of time optimising code which was not a problem in the first place. (: from experience :)

Can I use JMS instead of a shared database.

          I need to share data between mutiple weblogic instances and I would like to use
          JMS instead of a shared database.
          Senario:
          Weblogic instance 1 recevies message withy parameters 1,2
          Calcualate 1,2
          Weblogic instance 2 recevies message withy parameters 1,2
          Do not calculate 1,2 until Weblogic 1 is finish.
          I know I can persiste in a shared table the work currently being done but this
          alot on this table.
          I would like to use JMS to tell the other servers that I am working on a process
          so the other servers don't.
          My goal is to share data with multiple weblogic servers without going to the database.
          Is it possible?
          Any ideas?
          Tommy Lapierre


One way to accomplish this with queing is to partition
          related work to a single destination that has a single
          consumer.
