do index rebuild in bussiness hours creates any problem.i had still half an hour time for business hours.
out of 10 indexes still 2 indexes are left.please let me know your suggestions thanks.
thanks in advance
cheers :-)

Respond to what, exactly?
Oracle indexes do not need to be rebuilt as a general rule. There are some exceedingly rare cases where an occasional index may need to be rebuilt. But to have 10 indexes in a database that all need to be rebuilt would be exceptional. And your description doesn't seem to indicate any logical reason that any of your indexes need to be rebuilt. That leads me to strongly suspect that you are pointlessly rebuilding the indexes in the first place.
If you are going to pointlessly rebuild indexes (which I don't recommend), you should do it during system downtime windows when no one else is using the system. It would be better not to do them in the first place, but if you're going to waste cycles, at least waste nonproductive cycles.

If I change the nation setting of my iTunes in order to buy a song from the American iTunes store, then change my setting back to the Korean store (where you cannot buy music) will that create any problems with my downloaded content?

If I change the nation setting of my iTunes in order to buy a song from the American iTunes store, then change my setting back to the Korean store (where you cannot buy music) will that create any problems with my downloaded content? I want to buy an album that I cannot get hold of in Korea, but it is available in the US iTunes store. However since most of my apps are downloaded from the Korean store I'll need to switch back in order to update them. Does anyone know if there are any issues in doing this. I'd rather find out before I spend money, change my store setting back to Korea, and then get told I can't listen to the music because I bought it from the US store and my iTunes is set to the Korean store.
Cheers.

You canot easily change your country settings. The iTunes Store in a country is intended only for use by that country's residents, and only while they are in the country. 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. You are also restricted to waiting 90 days between country changes.

Sounds like you need to ask your question in the developers forums.

Will installing X11 update create any problem to my iMac?

While trying to run the recent Gimp update (2.6.4), the X11 needed to be updated to latest version (2.3.2.1). Apple installed version shows 2.1.5 on my iMac & software update is not showing the latest version.
So, I am hesitant (scared?) to install latest X11 version & keen to know anyone installed it without any problems to their Macs & other applications etc. Thanks for any input.
Best.

it's ok to install the latest version

I haven't done it but many people on this forum have. It works fine. the only thing you should remember is that you'll have to reinstall it after every system update.

My hard disk on my macbook pro is full and most of the memory is from iMovies. I have a back up disk which is 1 terabyte and I was wondering if it is possible to move all my iMovies onto it without creating any problems. If possible how do I do this?

Hi there, I am a great fan of doing films. the big problem is I have filled up the hard drive on my Mac Pro. I have 1 Teribyte Time Capsul where everything is automatically backed up. I want to use this to transfer my iMovies file to the Time Capsul to create more sapace on my MacPro. If I do this will it create problems when I use iMovie?
Could someone advise me the best way of doing this? Thnx!

DOES IT CREATE ANY PROBLEM BY NOT SAFELY DISCONNECTING?

I DID NOT SAFELY DISCONNECT THE FIRST TIME I PINNED MY iPAD TO MY LAPTOP. AND NOW I CANT CONNECT IT TO ITUNES IN MY LAPTOP ANY MORE NOR CAN I CHARGE WITH THE CABLE ??? IS IT JUST A CABLE PHYSICAL PROBLEM...OR ANY SOFTWARE TWEAKS ARE NEEDED?? PLEASE HELP .I PULLED IT WHEN IT WAS SYNCING ?? I KNOW I SHOULDNT DO THAT...BT I DID HELP WILL BE APPRECIATED.

It can.......
Yanking out a drive while it's being written to could corrupt the data. However, even if the drive isn't actively being written to, you could still corrupt the data. By default, most operating systems use what's called write caching to get better performance out of your computer. When you write a file to another drive—like a flash drive—the OS waits to actually perform those actions until it has a number of requests to fulfill, and then it fulfills them all at once (this is more common when writing small files). When you hit that eject button, it tells your OS to flush the cache—that is, make sure all pending actions have been performed—so you can safely unplug the drive without any data corruption.

Index rebuild

Hi Team,
Please tell me any difference b/w alter index <index> rebuild or alter index <index> rebuild move.
Is there any difference that more space will be released if I move index to diffrenet tablespace and move move back to orginal tablespace.
I know that if we use move option we can move index to different tablespace,
Regards,
jit

Even if you would do lots of dml's, that's not certainly means that you need the rebuilding of the index. If your assertion is based on this that there would be some "holes" within the leaf blocks which wont be reused and would require a rebuild, it's wrong then since Oracle would take care of these things on its own. So again, what criteria, other than an OLTP db you used to conclude that you need rebuilding of indexes?
But I just wanted to know If I go for alter index rebuild or alter index rebuild move and move back the indexes, which option will be best for me mean by which option I can reclaim more space.Well, I am sorry to say but I think you really don't know very well both the commands. The commands don't differ in the space reclaim given by them but in the way they do the rebuild. Please read the documentation to know what both commands do and how? BTW, from where you picked the command alter index rebuild move since I am not sure that such command exists?

Any problems with RH10 demo on the same machine as RH9?

I need to install the RH10 demo with captivate on a machine with RH9. Will that create any problems?

Both will run OK but Rh10 will become the version that opens when you double click an XPJ file. If you later uninstall Rh10 it may not revert to Rh## but a quick reinstall should fix that.
If you try to open an earlier version project, you will get a warning and the option to back out without upgrading the project. There are some hacks for reverting to an earlier version but they are not recommended.
Use copies of your Rh## projects to work in 10 while you experiment.
Ideally, use another machine.

Using COMPRESSION any Problem in Production ?

Hi All,
we are woking in SD application in BI7.0.
We plan to use the compression in SD application area for the Sales Cube (VBAK and VBAP), Delivery Cube(LIKP and LIPS ),Billing Cube (VBRK and VBRP ) and Shipping Cube ( VTTK and VTTS).
The infoproviders are used in the infoset.The below mentioned scenario occurs in the data loads of the infoproviders because of which decided to use the COMPRESSION:-
Sales Cube                                                                   Delivery Cube
Sales Doc        Sales Qty                                                Delivery Doc         Del Qty        Sales Doc
1                        11                                                        1                            11            1
1                        -10
1                        10
InfoSet ( Before Compression)
Sales Doc        Delivery Doc            Sales Qty            Del Qty
1                        1                            11                        11
1                        1                            -10                       11
1                        1                            10                        11
The report developed on the will show Sales Qty = 11, but Delivery Qty = 33. Which is incorrect.
To avoid the above incorrect data planned to use the COMPRESSION so that the infoset will get the data as mentioned below
Infoset(After Compression):-
Sales Doc        Delivery Doc            Sales Qty            Del Qty
1                        1                            11                        11
The report developed on the compressed infoproviders will show Sales Qty = 11 and Delivery Qty = 11. Which is correct.
Please give your suggestions that using the COMPRESSION do create any problems in the Production or is there any other way ?
Thanks in advance.

Hi ,
Thankyou for the above reply but as a precaution like to know that what are the scenarios where the COMPRESSION of the infoprovider creates a problem in Production System?
Thanks in advance.

My macbook seems to be going crazy. At certain points (and for hours) I get the oh snap page on chrome, safari doesnt work, macbook wont let me create any files or for example upload music to itunes. I restored my mac so im sure its not a malware problem.

My macbook seems to be going crazy. At certain points (and for hours) I get the oh snap page on chrome, safari doesnt work, macbook wont let me create any files or for example upload music to itunes. I restored my mac so im sure its not a malware problem. The only thing that solves it is switching off and on , but sometimes I have to do that for 6-7 times before its ok or wait for a few hours. Some help please

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

MV and index rebuild

Hi
Does rebuild (move to another tablespace) of indexes on a fact table in any way affect materialized views/logs created on that table? I know that it shouldn't but we have had some pretty strange things with our mviews, so i just have to ask :).
Thanks

It should not. What was the problem you had?

Goldengate Extracts reads slow during Table Data Archiving and Index Rebuilding Operations.

We have configured OGG on a near-DR server. The extracts are configured to work in ALO Mode.
During the day, extracts work as expected and are in sync. But during any dialy maintenance task, the extracts starts lagging, and read the same archives very slow.
This usually happens during Table Data Archiving (DELETE from prod tables, INSERT into history tables) and during Index Rebuilding on those tables.
Points to be noted:
1) The Tables on which Archiving is done and whose Indexes are rebuilt are not captured by GoldenGate Extract.
2) The extracts are configured to capture DML opeartions. Only INSERT and UPDATE operations are captured, DELETES are ignored by the extracts. Also DDL extraction is not configured.
3) There is no connection to PROD or DR Database
4) System functions normally all the time, but just during table data archiving and index rebuild it starts lagging.
Q 1. As mentioned above, even though the tables are not a part of capture, the extracts lags ? What are the possible reasons for the lag ?
Q 2. I understand that Index Rebuild is a DDL operation, then too it induces a lag into the system. how ?
Q 3. We have been trying to find a way to overcome the lag, which ideally shouldn't have arised. Is there any extract parameter or some work around for this situation ?

Hi Nick.W,
The amount of redo logs generated is huge. Approximately 200-250 GB in 45-60 minutes.
I agree that the extract has to parse the extra object-id's. During the day, there is a redo switch every 2-3 minutes. The source is a 3-Node RAC. So approximately, 80-90 archives generated in an hour.
The reason to mention this was, that while reading these archives also, the extract would be parsing extra Object ID's, as we are capturing data only for 3 tables. The effect of parsing extract object id's should have been seen during the day also. The reason being archive size is same, amount of data is same, the number of records to be scanned is same.
The extract slows down and read at half the speed. If normally it would take 45-50 secs to read an archive log of normal day functioning, then it would take approx 90-100 secs to read the archives of the mentioned activities.
Regarding the 3rd point,
a. The extract is a classic extract, the archived logs are on local file system. No ASM, NO SAN/NAS.
b. We have added "TRANLOGOPTIONS BUFSIZE" parameter in our extract. We'll update as soon as we see any kind of improvements.

Different b/w index rebuild and index rebuild online

hi..guys could u plz tel me difference between index rebuild and index rebuild online

There is no difference in both the commands. Both will rebuild the index structure from the scratch.But in the first case with only Rebuild, as long as the index, its temporary segment is not prepared and merged together, index is not available for the other users for use. The Online clause makes the index available for others even while being rebuild.
Rebuilding index online has the same concept of creating them online to some extent,

Amount of temporary tablespace size used for index rebuild

Hi All,
I want to know approximate amount of temporary tablespace size used for index rebuild. I need this information to avoid the insufficient temporary tablespace error during the huge index rebuild.
Is there a query or procedure to find it out.
Thank you.

Hi,
While creating the index, the temporary segment is created in the permanent tablespace. So permanent tablespace must have sufficient space.
