Performance on Schema based Xml and No Schema based XML
Hai,
We can insert two kind of xml like schema based xml document and non schema based xml document into XMLTYPE fields.I like to know which xml document will have good performance ( fast access ) compare to another.
Even if we have any other approach than schema.It will be great.
We do XPath query to get the values from xml document.Is there any way to get the fields faster than the XPath.I am using Oracle 10g R2.
I need to access much fast the xml element from the table.Please help me!.
Thanks,
Saravanan.P
HHave you read the FAQ or any of the XML DB whitepapers... If not I suggest that you do so before proceeding any further or asking any more questions. If you take the time to a do a little basic research you should be able to see that you have made the worst possible decision if performance is importantto you.
If you invested a little bit of effort before posting you would soon understand that in 10gR2 you will need to use schema based storage to get high performance, and that it doesn't matter whether you use XPath or XQuery, what matters is whether or not the XPath or XQuery operations get re-written correctly so the database can optimize them.

Impdp Performing a Schema-Mode Import Example
The Oracle docs ( http://docs.oracle.com/cd/B12037_01/server.101/b10825/dp_import.htm#i1006564) has an example of performing a schema-mode import as follows:
impdp hr/hr SCHEMAS=hr DIRECTORY=dpump_dir1 DUMPFILE=expschema.dmp
EXCLUDE=CONSTRAINT, REF_CONSTRAINT, INDEX TABLE_EXISTS_ACTION=REPLACE
Looking carefully at this example what does " INDEX TABLE_EXISTS_ACTION=REPLACE" mean, specifically with respect to "INDEX"?
Does it mean it will drop the table and associated index if it already exists and then re-create and load it using the dump file contents?Index is an argument to "EXCLUDE" and Table_Exists_Action is separate option. In this example, It is excluding Indexes during import. It has nothing to do with "TABLE_EXISTS_ACTION=REPLACE"

Lack of performance in SELECT-ing XML records
Hello Champs, I am new to XML world. But as a DBA now I'm into the situation to suggest better performance improvement in accessing XML records.
Problem:
There is a batch job from informatica, fetching records from XML tables(close to 400, one by one) stored in oracle database. All 400 tables just have two columns as described below:
Name Null? Type
RECID NOT NULL VARCHAR2(255)
XMLRECORD XMLTYPE
Each table has NORMAL index created for it only for VARCHAR2 column:
CREATE UNIQUE INDEX "username"."Indexname_PK" ON "username"."table_name" ("RECID") PCTFREE 10 INITRANS 2 MAXTRANS 255 NOLOGGING COMPUTE STATISTICS STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT) TABLESPACE "tbs_idx" ;
All the table has the CLOB index created for it with below description.
CHUNK PCTVERSION RETENTION FREEPOOLS CACHE IN_ROW FORMAT PAR
8192 14400 YES YES ENDIAN NEUTRAL NO
Informatica issues below query on all the table, where it could just fetch only 400rows/sec in average. This takes entire buisness day to complete the batch job for all 400 tables, which gives big problem in production environment.
SELECT <table_name>.<column_name>.getclobval() FROM <table_name>;

Many Thanks for your assistance,Not sure if you will like it, although it will improve your performance issues considerably, upgrade to Oracle 11.2.0.3 or 11.2.0.4 and be sure that all those XMLTYPE (CLOB) stored columns will be created/recreated with XMLTYPE (SECUREFILE BINARY XML).
One way of making sure that XMLTYPE will be stored via Binary XML Securefile LOB storage is by setting "db_securefile" on database level ( Using Oracle SecureFiles ) to value ALWAYS or FORCE. Binary XML Securefile XMLType content may only be created on ASSM enabled tablespaces... -
How to improve the query performance in to report level and designer level
How to improve the query performance in to report level and designer level......?
Plz let me know the detail view......first its all based on the design of the database, universe and the report.
at the universe Level, you have to check your Contexts very well to get the optimal performance of the universe and also your joins, keep your joins with key fields, will give you the best performance.
at the report level, try to make the reports dynamic as much as you can, (Parameters) and so on.
and when you create a paremeter try to get it match with the key fields in the database.
good luck

[8i] Performance difference between a view and an in-line view?
I have a query with a few 'UNION ALL' statements... each chunk of the query that is joined by the 'UNION ALL' references the same in-line view, but in each chunk it is joined to different tables. If I actually create the view and reference it in each chunk, will it still run the query behind the view for each chunk, or will it only do it once? I just want to know if it will improve the performance of my query. And, I'm not talking about creating a materialized view, just a regular one.
Because of the complexity of my query, I tried out a simple (really simple) example instead...
First, I created my simple view
Then, I ran a query with a UNION ALL in it against that view
Next, I ran the same UNION ALL query, but using in-line views instead of the one I created, and these are the results I got:

But, based on these results, I don't know that I can extrapolate to my complex query... or can I? I'm thinking I'm going to have to actually go through and make my views for the complex query and test it out.... -
Performance management with ONLY ESS and NO MSS??
Hello Gurus,
I have a very peculiar scenario regarding and ESS/MSS.
Let me first post our requirments:
We have implemented all modules of HR along with OM and now in the process of implementing Performance Management along with ESS only . I am stressing on ESS only here with NO MSS functionality.
Now my question is..is it really possible in the first place to have a performance management functionality without MSS and just with standalone ESS? If yes, what are the options that I have to configure the performance management system and the ESS system so that the workflows for Planning, Rating an employee, and Approvals regarding appraisals can be achieved??
Is it possible to assign an ESS role to the manager and then when the manager logs in ESS, he/she can go ahead with the performance management process and can check employees just like the way it happens in MSS?
Thanks a lot for your time.
Best Regards.
Karan.Dear Karan,
Firstly, it is not mandatory to implement MSS for approvals/notifications...
Manager in MSS term is used to refer Head of Unit (in general) and not the immediate supervisor, i.e, relation ship (012).
UWL - Universal Work List is the place where all work items for approval is listed and this can be activated in ESS with out using MSS functionality also.
Comming to Performance Managment: Yes it can be acheived. NO MSS is required for Appraisals.
if you are using BSP applications, there are different pages available for employee view, and manager view..\
all that u need to do is, use the appropriate pages in the links that you gonna provide in ESS>Performance Management.
SAP has given provision to create your own notifications (workflow) in configurations. Create a Z Event and ask your ABAPer to send a notification based on that Z Event. This all is standard.
Regards

Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
Hello,
I just want to reiterate that we are very committed to working on
this issue, and that our goal is to find out the root of the problem. But
first I'd like to narrow down the avenues by process of elimination.
Open Cursor is something that is commonly used in today's RDBMS. I
know that you must test your query in ISQL using some kind of execute
immediate, but Sybase should be able to handle an open cursor. I was
wondering if your Sybase expert commented on the fact that the server is
not responding to commonly used command like 'open cursor'. According to
our developer, we are merely following the API from Sybase, and open cursor
is not something that particularly slows down a query for several minutes
(except maybe the very first time). The logs show that Forte is waiting for
a status from the DB server. Actually, using prepared statements and open
cursor ends up being more efficient in the long run.
Some questions:
1) Have you tried to do a prepared statement with open cursor in your ISQL
session? If so, did it have the same slowness?
2) How big is the table you are querying? How many rows are there? How many
are returned?
3) When there is a hang in Forte, is there disk-spinning or CPU usage in
the database server side? On the Forte side? Absolutely no activity at all?
We actually have a Sybase set-up here, and if you wish, we could test out
your database and Forte PEX here. Since your queries seems to be running
off of only one table, this might be the best option, as we could look at
everything here, in house. To do this:
a) BCP out the data into a flat file. (character format to make it portable)
b) we need a script to create the table and indexes.
c) the Forte PEX file of the app to test this out.
d) the SQL staement that you issue in ISQL for comparison.
If the situation warrants, we can give a concrete example of
possible errors/bugs to a developer. Dial-in is still an option, but to be
able to look at the TOOL code, database setup, etc. without the limitations
of dial-up may be faster and more efficient. Please let me know if you can
provide this, as well as the answers to the above questions, or if you have
any questions.
Regards,

We did that trick already.
When it is hanging, I can see what is doing.
It is doing OPEN CURSOR. But not clear the exact statement of the cursor
it is trying to open.
When we run the query directly to Sybase, not using Forte, it is clearly
not opening any cursor.
And running it directly to Sybase many times, the response is always
consistently fast.
It is just when the query runs from Forte to Sybase, it opens a cursor.
But again, in the Forte code, Alex is not using any cursor.
In trying to capture the query,we even tried to audit any statementcoming
to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

GR/IR Clearing When to perform F.13/F.19 and MR11
Dear,
Can you pls explain GR/IR Clearing and its grouping, whats the process for GR/IR
adjustments done?
What is Grouping and Regroping?
When to perform F.13/F.19 and MR11?
I have read the threads discussed here on this topic, still I do not understand.
Thanks All
KrishnaHi
When we execute SAP124 (F.13) with the flag "only documents which can be cleared" it will display in detailed list only those documents that can be cleared.
If dont check this field it will generate a list even of documents that cannot be cleared.
In this case in OB74 you have given ASSIGNMENT and INVOICE REFERENCE as the criteria.
But what is probably happening is that the ASSIGNMENT is not matching in these documents and thus the system does not find
the item suitable or rather eligible for clearing.
If you check the documentation relative to the "Special processing of GR/IR clearing accounts" in SE38 -> SAPF124, you will find the following information:
"If you set the GR/IR accounts special processing indicator: The program then automatically uses the EBELN and EBELP fields as well a as the XREF3 reference field as grouping criteria.
This means that documents with the most recent posting date are initially ignored."
So the system is checking these three fields for grouping the documents.
For clearing GR/IR account it is not obligatory to set indicator GR/IR Account Special Processing. As described in note 546410 it can be more effective not use this indicator.
Also read note 546410 and 574482 thoroughly. -
5th generation ipod not detected by my windows xp. works fine on other pc. performed necessary steps to remove and reinstall itunes but having same issue. is there a driver i can download to pc then direct to that specific location when installing?
I have a similar issue - my iPod nano connects and is visible in Device Manager yet invisible in My Computer and iTunes. I've tried everything I can possibly think of to try and solve this myself, all in vain.
Mine is a nano 4G. I've been using it for quite some time without the slightest problem. I have been using WINAMP instead of iTunes to manage my darling nano.
Then, one fine day I bought a new computer and the nano would not show up in My Computer, though the nano display shows "Do not disconnect". On my old computer it worked (and still works) absolutely fine with win XP as well as with win7 (the later I currently use on my new/problematic computer, which I bought last summer and that's how long I've had this problem).
Of course, after several first attempts I gave up and installed iTunes. I've tried using the Apple support article "iPod not recognized in 'My Computer' and in iTunes for Windows":
- reset
- fully charged,
- cable works fine on two other computers
- in normal or disk mode makes no difference
- tried to find anything useful in the diagnostics mode
- reinstalled iTunes several different times since then to the latest version
- I've unplugged every other USB device except for my mouse and keyboard and tried several different USB ports on my motherboard (USB 3.0 and conventional), as well as trying different USB- related options in my BIOS.
- I've never used any Mac with this ipod
- I've tried fiddling with the win7 Services by stopping and restarting them and of course
- uninstalling the iPod drivers in Device Manager. After such an uninstall the ipod would automatically be recognised and "ready for use", i.e. being invisible in My Computer.
- Attempted to find any possible third-party conflict with msconfig or the possibility that my ipod is being confused for a network drive (for which I've disconnected my HDD, leaving only my SSD with the OS).
Sometimes, iTunes would note that iPod service (or something, can't remember exactly) failed to install properly and asked to try and repair it. I would click YES! and voila - no change! The ipod would rarely show up in iTunes on my problematic computer like this:
iTunes would warn me that the nano would need restoring so I would try and do it on my haunted machine upon which iTunes would freeze like you seen in the picture.
Despite this, I've updated and restored the nano on my father's computer to the latest version without any problems. This though, did not solve my problem in any way.
I can load music to my nano through my old computer (which for me is a real pain and hassle) and the gadget works normally in terms of its disconnected functionality.
I've taken my nano to the local service for repair and they said it was fine. Mercifully, they didn't charge for the diagnostics service (gee, thanks for not ripping me off!).
Here are two screengrabs from my Device Manager
and Devices and Printers screens on my comp:
That is my sad story as far as I can remember. It's most likely something with the drivers or something along those lines though I'm out of ideas at this point.
If you think you have any idea PLEASR HELP, I'M DESPERATE! -
My problem started when I found a trojan (win32/skeeyah.B!plock) in my computer. Both Windows Defender and Malwarebytes detected it and claimed to remove it, but to be sure it was gone (I read online that it's hard to get rid of that one) I decided to perform a reset. I chose the deep reset option, it took about 5 hours to reach 92%, and then I got a message that the reset had failed. It gave me some options, and I chose to repair windows so I could keep using my machine. I had to set it all up again, like windows was really installed again. It seems to be working fine but it's a bit sluggish, and it bothers me that the reset failure might have left some broken files.
After testing it for a while, my only problem other than sluggishness was that I couldn't install google chrome ("Clickonce_bootstrap.exe - system error" was the message I got when the installation failed) but it bothered me enough to want to perform a refresh, to fix anything that might have been left broken. When I tried to do this, I got a message asking me if I trusted the source of the files that were attempting to perform changes on my computer, and listed my own hard drive as the source. I chose to trust it, and then I got a message telling me that the files needed to perform the refresh weren't in my computer, so I was prompted to insert the install disks. They didn't come with my laptop (Dell Inspiron), but I saved the installation files into a usb stick before doing the reset (Using Dell Recovery and Back Up), so I inserted the usb, and it told me that these weren't the right files. After that, my only option was "Cancel". Same thing happened for both refresh and reset.
Like I said, the computer seems to be functional, but I'm afraid the system might be unstable and crash on me randomly. Is there anything I can do?Do not reinstall Windows 8, it is obsolete. Instead make installation media for Windows 8.1 with Update 1:
http://dellwindowsreinstallationguide.com/download-microsoft-windows-and-office/download-microsoft-windows/download-windows-8-1-retail-and-oem-iso/
The only problem is selecting the correct edition likely Windows 8.1 or Windows 8.1 Single Language.
Use DISKPART → CLEAN ALL:
http://dellwindowsreinstallationguide.com/cleaning-up-a-drive-format-vs-secure-wipe-ssd-and-hdd/
Then install Windows 8.1 with update 1 directly:
http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/a-clean-install-of-windows-8-1/windows-8-1-installation/
You can install with a local account, then install the system drivers in the correct order:
http://dellwindowsreinstallationguide.com/downloading-drivers-checking-hardware-ids-and-downloading-and-installing-dell-system-drivers-in-the-correct-order/driver-installation/
If you need help identifying variants provide hardware IDs:
http://dellwindowsreinstallationguide.com/downloading-drivers-checking-hardware-ids-and-downloading-and-installing-dell-system-drivers-in-the-correct-order/checking-hardware-ids-in-the-device-manager/
After installation of the drivers you may then install Dell Backup and Recovery the latest version is here:
http://downloads.dell.com/FOLDER02909509M/1/Backup-and-Recovery_Application_64M9D_WN32_1.8.1.71_A00.EXE
This will create a new recovery partition on your system that is Windows 8.1 with Update 1. You may then switch for a Microsoft Account. -

I started getting a Timed Out error message on my iPhone 5 when trying to browse the internet tthat reads Page could not be loaded. Connection timed out. I performed a Reset Network Settings and am still getting the error message. What is the fix?
Thanks so much for more direction.
I realized that I bought this iPod T4 about a year ago, so decided to check the date and it is still under the 1 year ltd. warranty until 21 Dec. I contacted Apple via Chat and was informed that the problem may lie in the version of iTunes I was running 10.7. Today Apple released v. 11 of iTunes which I was instructed to download. It's TOTALLY different from iTunes 10.7 - drastically different in fact.
The Apple Chat Rep set up a phone call appointment forl 8:00 pm ET tonight where another Rep will call me to make sure the restore was accomplished OK. With v. 11 of iTunes I can't even find the restore option!!! The phone Rep will have to help me navigate v. 11 of iTunes. It doesn't seem intuitive at all. Maybe it's just me?!?!
Thank you for sending this new link for firmware. It's not clear to me right now whether I'll need it or not. The phone Rep will probably somehow be able to resolve the problem. If not, they'll probably send me to the nearest Apple store if the problem is hardware, as it would be covered under the warranty. I will give another update as to what transpires as a result of the phone call with the Apple Rep.
Again, thank you so much for helping me. -

Hi there,
You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.
Thanks, let me know if the update helps,
