Any 10.2.0.3 ASM experience for dwh?

We want to test and use ASM on a single instance 10.2.0.3 database with solaris 10 and emc storage for our datawarehouse environment. So please if you have any experience can you advice on below questions;
1. any kind of bugs you might have experienced on this release?
2. any kind of test experience which you might advice to check for both performance and availability of ASM?
3. Some init.ora parameter which may be critical for a dwh ASM?
4. how ASM instance can be backup up, no export or rman seems to be available?
5. what is the best method to migrate xxTB of data on tru64 filesystem emc source to solaris emc asm target environment?
Thank you.

1) We had bugs but with the DB and not with ASM. Others may have experienced bugs specific to ASM but I have not.
2) I think you would want to look at your waits. See what your disk seek time is. Again, that goes back to doing what you would normally do whether it was asm or not. The difference is with ASM you need to run queries and even use Grid Control to see how it is performing. If you really want to do ASM, buy the new Oracle ASM book from Oracle Press.
3) It's in the documentation. ASM has it's on init.ora file.
4) ASM is basically disk groups of disks. You want your DB to be backed up. Obviously there are things you can do if you lose a disk, but that's just as if a disk went bad. Worse case scenario you recreate your ASM instance and readd your disks and then restore your DB.
5) With 5 you may want to look at Transportable Tablespaces and RMAN. GC gives you a GUI but I don't think it will give you all the detail you need.
I would recommend you read through the docs and buy that ASM book.

ASM module for kernel 2.4.21-27EL

Does anybody know from where I can download ASM module (RPM or source) for kernel 2.4.21-27EL . I managed to install ocfs module with that kernel using ENBD - project for network shared storage, but the ASM module for kernels 2.4.21x is compiled for 2.4.21-19
the source supports only 2.4.19...
Any idea anybody?

Better user experience for slow reports (loading in background, progressbar

Hi
In our application, some reports take a long time till they are displayed. Therefore it would be nice, if i could provide the user with some feedback (example: progressbar). Is it possible to have this? Upon print, when a pdf file is being constructed (in web) we already have such functionality in place, is it possible to have it generally?
Mayb,e it would also be possible to have the report load the first page quickly, so the user has already something to look at, and load all the other needed data in a background thread. (i dont think it is possible, however, somebody may have an idea)
Does anybody have an idea how we could achieve a better user experience for our reports. Any help is appreciated. Thanks.
Greetings
I am using:
Crystal Reports 2008 (in Asp.net, Windows Forms)
Version .NET 3.5 (SP1)
PS: of course a very fast report would be the finest solution. However, i guess this will not be possible with our reports and the volume of data they access

Hi Daniel,
Crystal Report 2008 we have a inbuilt functionality of progress bar .If you are not getting progress bar for every report that means those reports are not taking to much time.
For more info regarding progressbar this check this link:
[https://boc.sdn.sap.com/node/8035]
Look for processingIndicatorDelay and processingIndicatorText.
If you want to improve performance of report then we need to keep in mind few thing while creating report in Crystal report designer:
Here are a few points related to performance issue .
The performance of a report is related to:
External factors:
1. The amount of time the database server takes to process the SQL query.
( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
2. Network traffics.
3. Local computer processor speed.
( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
4. The number of records returned
( If a SQL query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
Report design:
1. Where is the Record Selection evaluated?
Ensure your Record Selection Formula can be translated in SQL, so the data can be filter down on the server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated
in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to
SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
2. How many subreports the report contains and in section section they are located.
Minimise the number of subreports used, or avoid using subreports if possible because
subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100
records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest
factor why a report takes a long time to preview.
3. How many records will be returned to the report.
Large number of records will slow down the preview of the reports. Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report off a Stored Procedure, or a Command Object that only returns the desired data set.
4. Do you use the special field "Page N of M", or "TotalPageCount"
When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page
of the report before it displays the first page, therfore it will take more time to display the first page of the report.
If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't use when you view a report it only format the page requested. It won't format the whole report.
5. Link tables on indexed fields whenever possible.
6. Remove unused tables, unused formulas, unused running totals from the report.
7. Suppress unnecessary sections.
8. For summaries, use conditional formulas instead of running totals when possible.
9. Whenever possible, limit records through selection, not suppression.
10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports.
SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
11. Using one command as the datasource can be faster if you returns only the desired data set. It can be faster if the SQL query written only return the desired data.
12. Perform grouping on server
This is only relevant if you only need to return the summary to your report but not the details. It will be faster as less data will be returned to the reports.
Hope this helps!!

Shweta

Does anyone have experience for disk damage and loss?

Does anyone have experience for disk damage and
loss for B1? What's the procedure to get new one?
Any cost involved.
Regards,
Kenneth

Hi Kenneth
Usualy we take the strongest measures to avoid that and never let it come to that. You should of had back up's running on and off site. How bad is your problem?? I'm assuming you are talking abou a hard drive that is faulty. Have you tried restarting in Safe Mode??
You get experts that can retrieve data from a hard drive depending how bad the problem is. It usualy cost more than the Hard drive......but if you are desperate and value your data you'll do it.
Hope this helps

Can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

Hi ,
Hardware Requirements
Physical memory (at least 1.5 gigabyte (GB) of RAM)
An amount of swap space equal to the amount of RAM
Temporary space (at least 1 GB) available in /tmp
A processor type (CPU) that is certified with the release of the Oracle software being installed
A minimum of 1024 x 786 display resolution, so that Oracle Universal Installer (OUI) displays correctly
All servers that are used in the cluster must have the same chip architecture, for example, all 32-bit processors or all 64-bit processors
Adequate disk space in the software installation locations to store the Oracle software
You need at least 5.5 GB of available disk space for the Grid home directory, which includes both the binary files for Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM) and their associated log files, and at least 4 GB of available disk space for the Oracle Database home directory, or Oracle home directory.
About Shared Storage
These Oracle Clusterware components require the following disk space on a shared file system:
Three Oracle Clusterware Registry (OCR) files, 300 MB each, or 900 MB total disk space
Three voting disk files, 300 MB each, or 900 MB total disk space
If you are not using Oracle ASM for storing Oracle Clusterware files, then for best performance and protection, you should use multiple disks, each using a different disk controller for voting disk file placement. Ensure that each voting disk is configured so that it does not have share any hardware device or have a single point of failure.
Network Hardware Requirements
When you configure the network for Oracle RAC and Oracle Clusterware, each node in the cluster must meet the following requirements:
Each node must have at least two network interface cards (NIC), or network adapters. One adapter is for the public network interface and the other adapter is for the private network interface (the interconnect). Install additional network adapters on a node if that node meets either of the following conditions:
Does not have at least two network adapters
Has two network interface cards but is using network attached storage (NAS). You should have a separate network adapter for NAS.
Has two network cards, but you want to use redundant interconnectsIn previous releases, to make use of redundant networks for the interconnect, bonding, trunking, teaming, or similar technology was required. Oracle Grid Infrastructure for a cluster and Oracle RAC can now make use of redundant network interconnects, without the use of other network technology, to enhance optimal communication in the cluster. This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2).Redundant Interconnect Usage enables load-balancing and high availability across multiple (up to 4) private networks (also known as interconnects).
However, When you install Oracle software, Oracle Universal Installer (OUI) automatically performs hardware prerequisite checks and notifies you if they are not met.

Is there going to be any more online training courses released soon for BC? Anywhere?

Is there going to be any more online training courses released soon for BC? Anywhere? I'm seriously baffled by the lack of educational meterial out there. ALL of the adobe tutorials are out of date and the subjects are on small fragments of the whole platform. No complete training packages but one out there. I don't mind paying for it but I need a full and complete online training process, experience that isn't all over the place. I can't even find any books that are on the current version of BC.
Why is there a serious lack of traning out there for BC? I just can't figure it out.

Have you not checked out any of this?

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

Is there any downside mixing Objective-C with C++ for iOS apps?

I'd like to use C++ since it's fast and more dynamically in memory reference.
Is there any downside mixing Objective-C with C++ for iOS apps?
When googled for info, I only found tutorials about how to let xcode compile Objective-C with C++.
Thanks for help.

Both Objective-C and C++ are (more or less) extensions of C.
C supports manipulation of pointers and casting of pointers, this implies that both Objective-C and C++ will be able to manipulate C data like arrays, structs ...
Objective-C has classes like NSData to read/write blocks of bytes from/to file and to access ranges of bytes when the data is loaded into memory.
C++ probably has similar classes (I'm not well versed in C++ so I don't know).
If you want to look into using C++ you will probably want to look at Objective-C++, the link below has links to docs on how to use C++ with Objective-C:
http://stackoverflow.com/questions/3684112/what-is-objective-c
Thanks for the info, NSData does what I need.
A replied in the link also mentioned that he's using C++ in his application too. As long as I'm aware of memory management (prevent memory leaks, etc) as @disguise said, it should be fine.
@etresoft indeed, but C is the base language of ObjC, there are ways to deal with.

You should remove his AppleID and restore it as new.

I can't change my apple id password because my security answers don't match. It won't give me any other options and just keeps asking for the answers. What do I do?

My family shares one apple id. Is there any way to make an apple id for each member of my family and have it all connected to the same credit card and have the same previous downloads open to download by signing in to each members personal apple id?

Hi cindy,
If you all have individual Apple IDs, then you would be able to dowload music from a shared iTunes library on a computer, but you would not be able to sign on each individual ID on an iOS device in order to download music purchased under the original Apple ID without a 90-day waiting period between sign-ons.
Here's what I mean:
If you were to sign on a new Apple ID on, say, an iPhone, and then were to purchase and download some music from iTunes, then you would have to wait 90 days before you could sign on the old Apple ID to that iPhone in order to download previously purchased material (and vice versa).
However, if all of the music purchased by that origjnal Apple ID is in an iTunes library on a shared computer, then you can hook up the device and selectively sync any music in that library to the device. You can also sign on any of the Apple IDs to that shared iTunes library and purchase music to be added to the library.
You would need to authorize the computer for each of the new Apple IDs.
Each of the Apple IDs would also be able to download that music purchased either by syncing to the iTunes library on the computer or by downloading it OTA on the device.
So, each Apple ID can download music, movies, etc. purchased with that Apple ID OTA to the device. Also each Apple ID can sync any music, movies, etc. that are in the iTunes library on the computer regardless of who purchased them.
The only other thing you would need to remember is that if an App needed to be updated, then the original Apple ID that was used to purchase that App would come up, and the password that goes with that Apple ID would be required to do the update.
Hope that helps,

Is there any way to create admin role only for one resource.

Hi all,
I am trying to create an admin role with 'update user' capability. But I want to restrict the user(with the admin role) to be able to update a user's attribute only for one resource, The user(with the admin role) should not be able to update the attributes of the other resources which a user have.
Is there any way to create admin role only for one resource?
I customized the tabbed user form to show only one resource attribute (deleting the missing fields and adding my tab for the resource) and then assigned this new User Form to the user(with the admin role) in security tab.
It works fine. But the problem is that if any user(with the admin role) is also admin of some other resource then he/she will not be able to view the other resource attributes.
Please suggest,
thanks

Hi,
As you may remember there used to be a Messages pane to the Preferences where the Font and colour of the Balloons or background and the Font text colour could be changed.
And there was a Format Menu for character, word and Sentence changes in the current IM or iMessage.
Those have gone in Yosemite's version of Messages (Despite it retaining the designation of Messages 8 the same as Mavericks' version).
All that can be done now is set the size of the font and this has been moved to the General Section of the Preferences.
The Yosemite version has also been fixed to using the Balloons style of send and receiving any type of messages as well.
Changing the Font would involved editing the Balloon.transcript file.

Options for when an iOS device gets locked because of forgotten passcode:
Restore (and reset passcode) on your device by connecting it to the last computer to which it was connected:
iTunes: Backing up, updating, and restoring iOS software - http://support.apple.com/kb/HT1414
If you cannot connect it to the computer to which the device was last connected (or the device was never connected to a computer) you will have to use recovery mode to completely reset the device, losing all data:
iOS: Unable to update or restore - http://support.apple.com/kb/HT1808 - recovery mode (e.g., cannot connect to computer last used to sync device, iTunes still asks for a password)
