LKM step Load huge data very slow

Hi ALL,
when you try to load 4 million data from flat file to my oracle database.
it took me around 2.5 hours to finish the step 3 "LOAD DATA" which i thought odi will load data from flat file to C$ table.
it is anyway to speed it up?
I just chose the simple LKM FILE TO SQL option.
thanks
I Z

this is only the step 3 create temp table. it is nothing about the sql load yet.
create table <%=odiRef.getObjectName("T"+odiRef.getTableName("COLL_SHORT_NAME"),"W")%>
<%=odiRef.getSrcColList("","[COL_NAME] [DEST_CRE_DT]","[COL_NAME] [DEST_CRE_DT]",",\n","")%>
<%=odiRef.getUserExit("WORK_TABLE_OPTIONS")%>
this one will auto-generate the sqll like
create table ESBUSER.TC$_0TEST
ROW CODE VARCHAR2(1), --> this one is auto-generated by the above code. i have not way to change ROW CODE TO ROW_CODE.
B VARCHAR2(20),
C VARCHAR2(20),
D VARCHAR2(40)
i dont know why it will generate the ROW CODE......without the "_"...
please help
thanks

SQL loader load data very slow...

Hi,
On my production server have issue of insert. Regular SQL loder load file, it take more time for insert the data in database.
First 2 and 3 hours one file take 8 to 10 seconds after that it take 5 minutes.
As per my understanding OS I/O is very slow, First 3 hours DB buffer is free and insert data in buffer normal.
But when buffer is fill then going for buffer waits and then insert is slow on. If it rite please tell me how to increase I/O.
Some analysis share here of My server...................

4G LTE data very slow or nonexistent in San Diego inland North County area?

Over the past few weeks I've noticed my phone being a bit slower than usual with data speeds in terms of loading a web page, various, apps, etc. Phone is a HTC Thunderbolt.
However this week since 1/6/2014 and usually in the morning when I'm at work (Poway, CA 92064) my data is VERY slow and goes all over the place from 4G LTE to 3G to 1X and even spends periods of time with no data connection whatsoever even though I have several bars of service. Was just out to lunch in San Diego/Scripps Ranch 92131 and still had 1X or no data service at all. This is becoming downright unacceptable as I am paying for this service and it's nonexistent for large periods of time.
I'm not sure this is limited to a local problem though. My partner is in the Bay Area hundreds of miles away from here and he said his phone (HTC Rezound) the other day also spent a lot of time on 1X and wore his battery down unusually early searching for a data signal.
Verizon...what the heck? What's up?

It may be that there working on the system in your area or are they having any special events in your when they do that can tax the system some what and it cause what your seeing.. You might want to give Customer Service a call and ask for a Tech Rep.. see if there having any issues in your area and while your on the phone with them, have them check your PRL code.. it may need updating and the rep may have to push it to your phone.. b33

SudhirOne method is to use SQL Loader (sqlldr)
Another method is to define an external table in Oracle which is allowing you to view your big file as a table in database.
You may want to have a look at this guide: Choosing the Right Export/Import Utility and this Managing External Tables.

Stepping through table is very slow

LV 7.0 on Win 2K
I use a table to display records of information. The table is filled once at entry to a user interface subprogram and the user has the possiblity to select certain records by clicking or stepping through with the cursor buttons.
I have also written subprograms to sort the table by the various columns. The active row is used to provide more information e.g. displaying it in an image.
Usually you would click on a line with the mouse, but somtimes it is more convenient to step through subsequent lines with the cursor buttons.
As it turned out the latter is sometimes very slow.
I tried to trace that behaviour in my program, but it seems that the problem is within labview. I reduced the vi to a simple loop
where nothing is done with the table except to display the value. If you click on a line the value will follow instantaniously. If you click on a line at the top of the table and then step down with the cursor buttons the value will also follow very quickly. But when you do the same while beeing at the bottom this will take several seconds.
I read several entries in the forum that describe similar problems when updating the table. Please note that this is a very static table here. The only thing that is happening, is a user interacting with it with the keyboard.
The answers I saw so far, suggesting to keep the table small, or switching to other indicators etc. seem to overlook the reason why to use the table; that is tp have a compact display of a lot of ordered information. If the reason is really within LV runtime. Than NI has a nice task to improve LV next time :-(

Unfortunately, I can confirm that LabVIEW 7.1 shows the same slow behavior. Actually pressing "down arrow" on my rig is so slow, it seems to lock up the PC. (W2k)
Interestingly, if you capture the "up" and "down" arrows with a filter event, there is no slowdown! Maybe you can used the attached rough draft (LabVIEW 7.0) to improve the UI experience to the user until NI fixes the issue.
Enjoy!

Yahoo Finance Portfolios - add/remove page and update data very slow to load

The Add/Remove symbols page only partially loads then stops dead. Can take a minute or more to complete loading. And when I try to update quantities or price I get a whirling color gif which only sometimes reaches the point of letting me load data. Firefox, no problem.
Thanks!

Mobile LTE data very slow - 80026

I have been experiencing a massive drop off in data of up and down data speeds in Lafayette, Colorado (80026).
Speedtest is giving me anywhere from 47ms to 457ms pings and data speeds up/down of as low as .54/.28 respectively. This is becoming more and more frequent with the tests trending slower and slower.
I've reset the device and network setting on the phone (iPhone 5s) to no avail. It shows 2 or 3 bars and "LTE" when these tests are run.
Not quite sure what the next steps are for troubleshooting or reporting this as the Support sections oddly make no mention of connectivity or data speed issues as topics. Or if they do, they are buried deep or in a category I am not identifying. Something that would presumably be near the top of users' support issues, I would have thought would warrant higher level visibility. Perhaps room for improvement for customer support there?
Anyway, any thoughts? Is this a temporary issue? Where should I be reporting this? What remedies, if any, should I be seeking? Are there prescribed troubleshooting steps?
Also also, the "tags" field in this forum software doesn't seem to support ZIP codes as a standalone tag as it won't let me enter more than two digits (Mac 10.9.5, Chrome 39.0.2171.99).

Hi Sarah, thank you too... I'll likewise try to answer as best I can, as well as add a bit more data:
I haven't been able to identify a pattern as to when the slowdowns happen except that it is happening far more often than it used to. I'll try and log it.
I am using the Ookla Speedtest tool (as it is installed and convenient on the device) to ping a variety of networks and test up/down speeds with sample packets. If I am feeling very fancy or annoyed I sometimes even tether my computer and run more advanced network tests from the terminal so I can see if there is a routing issue. But as of yet, the slowdowns appear to be entirely in Verizon IPs.
The bit more data: my wife and neighbors who are on Verizon are also telling me that they are seeing significant data slowdowns regularly from Lafayette (80026) as well as in south Longmont (80501). None of them have reported it to Verizon as they "don't know how", not that I blame them as "data speeds" or something of that ilk is not a service category under the predefined "Topics" for some reason... and my wife leaves these sort of things up to me anyway.

Duplicate records found while loading master data(very urgent)

Hi all,
One infopackage in the process chain failed while laoding the master data(full update).Its showing the following error-->duplicate record found ..1 record used in /BI0/PTCTQUERY and the same record occured in /BI0/PTCTQUERY tables.
can anyone give me the solution...its very urgent...
Thanks & Regards,
Manjula

Hi
You can see the check box in the Processing tab page. Make a tick mark for the check box Ignore Duplicate Data Records indicator . When multiple data records that have the same key are transferred, the last data record in the request is updated to BI. Any other data records in the request with the same key are ignored.
Help says that:
To maintain consistency, ignoring duplicate data records is only possible if the data is updated serially. A serial update is when data is first updated into the PSA then, after it has been successfully written to the PSA, it is updated into the master data or text tables of the InfoObject.
If a DataSource transfers potentially duplicate data records or if you manually set the Ignore Duplicate Data Records indicator, the PSA Only update type is automatically selected in the scheduler.
hope it clears ur doubt, otherwise let me know.
Regards
Kiran

Since a week or 2 Firefox has been loading web pages very slow. Or it does load them but it takes a good 3 seconds before i can scroll or enter anything.

This morning also it froze up for a good 10 seconds and then it loaded the web pages again. Especially when i am browsing on a forum and return to main page or something. It just takes ages before i can select anything. It loads somewhat slower also but the part of it that i cannot select anything or scroll down before it stops thinking.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.
*http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox
*https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file
You can also try to repair the places database with this extension:
*https://addons.mozilla.org/firefox/addon/places-maintenance/
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Photoshop loading photo files very slow (not printer)

For the past several weeks Photoshop C3 has been loading even the smallest of photo files very, very slowly -- about 10-15 seconds for one.
I read an earlier post to this affect, that said it might be a networked printer, but the printer on this computer is NOT networked.
I'm running Windows XP, latest update, with 3 gig of RAM. And we have deleted and reloaded the Photoshop program and updated it to make sure it's not a file goober in the program.
Anyone else experiencing this trend and/or have any solutions.

John:
Thanks for the effort, but alas it didnt make any difference.
Our IT support crew tried a variety of generic drivers in the default mode, but a 56k photo still took 15 seconds to load.
However, I still had a version of "Photoshop CS" on my machine. So, out of curiosity I fired up CS and grabbed the same test photos, and bam the photo popped right up. So it is definitely a CS3 issue
Any other solutions that you know of?

Huge data on slow network

Hi All!!!
I have a client which connect to the database through slow network (2Mbit/s) with slow response time:
PING (10.6.0.5) from 10.1.9.24 : 56(84) bytes of data.
64 bytes from (10.6.0.5): icmp_seq=1 ttl=124 time=115 ms

SSIS Moving data very Slow

We have a large table roughly 200 GB that we are attempting to migrate from one server to another. We are attempting to use SSIS and the table has an image type and a text data type. I’ve tried to tune my ssis package by altering the BufferTempStoragePath, BLOBTempStoragePath, DefaultBufferSize, and DefaultBufferMaxRows properties but the transfer still takes extremely long (Up to 15 hours). The table is 15 million rows. I’ve also attempted to run my ssis in chunks as high as 1 million per data flow task and as low as 500000 per data flow task. If I attempt to transfer 250000 records at a time it starts out transferring pretty fast then it slows down drastically once it gets to about 800000 records. I’m using SQL Server 2005 x64 bit on Windows Server 2003 R2 with SP2. I have 16gb of memory on the target server on the and 8 GB on the source. Are there any other changes I should consider?

Matt,
Is that behavior with swapping of BLOB/CLOB columns out of to disk documented? I don't remember reading about it.
Yep, it sure is. What Matt M refers to is the fact that a BLOB cannot fit into the data flow buffer. When this happens, the BLOB data gets written to the directory (optionally) specified in the Data Flow parameter, BlobTempStoragePath, or the directory stored in the "TEMP" environment variable.
It is in the description of that property where you will see the confirmation of Matt's statement, "When the data flow task processes a column containing BLOB data that is larger than the available memory on the system it temporarily writes data from the BLOB to the file system."

That description is a bit misleading, as I suspect the phrase "...larger than the available memory on the system" also includes being able to fit into the data flow buffer, which ever is smaller.

Why first time loading ReportViewer object very slow

I am interested to know why the first time .net applaction loading the ReportViewer object so slow. It might take over 60s. Is this a performance issue or we need preload the object?

Hello Steve,
if you view a report for the first time the report viewer needs to load all dlls needed to connect to the database and to render and display the report. These dlls stay in memory a certain time afterwards.
That is why the report takes much longer to display the first time.
