Change number of data file
I need to copy the data files to a SAN and want to change the number of data files form 4 to 1. This is only a small database (22Gb). I don't know how to delete the data files and re create them.
Regards
Hans
Hi Hans,
no, you can also do it using DBMGUI. The process is really the same as when you're doing a homogenous system copy, the only difference is the target itself is the same db instance.
You'd have to make sure you've backup up all (data+log) and no further data was created (for example by making a full data backup in ADMIN mode and saving the log). Then you'd need to initialize the DB and specify the desired number of (data) volumes and make sure you select the radio button labelled 'Create instance for recovery' during the initialization process, so the instance will only be put into ADMIN, after which you can then recover (using the backups made in the beginning).
I'd recommend to test this out yourself on a small (non production) db instance.
In comparison, from MaxDB version 7.6.00 Build 22 onwards, you would just have deleted the unwanted volumes (taking into respect that the left over volume can hold all data).

Roland

How to increase number of data files parameter
Dear All,
I am facing problem in increasing number of data files associated with the DB. I have DB_FILES = 200 and want to set it to 300. DB was started with SPFILE.
Tell me how to increase this parameter. I dont want to stop DB also. I will be thankful if anyone guide me in both ways to stop DB and without stopping it.
Regards
Aqeel NawazMadrid,
Please don't take it as nit-picking.Just wanted to point an enhancement in 10g regarding recreating control file for increasing number of datafiles.I am sure you must be aware about it.
Please see this link and this note,
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/dfiles.htm#sthref1340
When you issue CREATE DATABASE or CREATE CONTROLFILE statements, the MAXDATAFILES parameter specifies an initial size of the datafile portion of the control file. However, if you attempt to add a new file whose number is greater than MAXDATAFILES, but less than or equal to DB_FILES, the control file will expand automatically so that the datafiles section can accommodate more files.
From 10g onwards,the requirement to recreate teh control file is lifted.
Please correct me if I interpreted the note in a wrong way.

Database files
Maximum per tablespace Operating system dependent; usually 1022
Maximum per database 65533
May be less on some operating systems
Limited also by size of database blocks and by the DB_FILES initialization parameter for a particular instance

I understand the DB_FILES part but how come number of files per database be limited by the database block size?
The maximum number of datafiles per database is 65533 as per above quote.
Could someone please explain this?

Change delimiter "download data" file
Hi,
i want to change the delimiter for the download data option from a report. How can i do this? I( thought it would take it from the reginal settings from your system, but it's not.
regards,
OsmanI don't have a full OBIEE installation to test but in 10.1.3.3.2, you have tabulation.
May be in the last version, they have change the format and give it a more standard.
http://en.wikipedia.org/wiki/Comma-separated_values#Basic_rules
The delimiter can change depending of the country from a comma to a semi-colon.
I can check the language file parameter. They don't give me an access but you can test the parameter in this file
OracleBI/web/config/localedefinitions.xml
I see this node by language.

How can I return to a previous version that did not have problem? On Safari on my lap top Mac, I do not have this problem. We tried this on another Windows computer with a 3.5 or 3.6 Firefox version and there was no problem.
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site. Note: this is likely to log you out, so finish up whatever you are working on first.
1. Clear Firefox's Cache
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Offline Storage : "Clear Now"
2. If needed, delete the site's cookies here
While viewing a page on the site, right-click and choose View Page Info > Security > "View Cookies"
Then try reloading the page. Does that help?
Some sites appear to be incompatible with Firefox 5. The difficulty is tracking down the problem. To see whether it is caused by the new stricter HTML parser in Firefox 4+, you can turn that off. Please save any unfinished work first.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''html5''' and pause while the list is filtered
(3) Double-click '''html5.parser.enable''' to toggle it to false (it should turn bold).
Then return to the problem page, reload and try again. Does that make any difference?
Here's the process to roll back if needed:
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 5.
You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.
Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details. -
Palm Desktop datebook data file
I've been a Palm user for 13 years.
A year ago, my trusty Z-22's battery died. So I bought a M500 online from one of Amazon's 3rd party vendors. It worked adequately, but with a number of glitches that I learned to live with. By July or so of this year, I noticed appointments randomly disappearing from my desktop Palm app. No rhyme or reason, past, future, etc. I kept many data backups and just kept putting those files back into the desktop.
Then Oct 1st, everything on the calendar disappeared. 13+ years of data, gone. Fearing it was the funky M500 (fortunately I did not sync after the data loss, so had the entire calendar on the handheld), I bought a refurbished Z-22 from an Amazon 3P. Uninstalled desktop software (saved all data files), downloaded the latest Palm desktop software I could find (v. 6.2.2), loaded all data files, back in business. Everything worked like a charm. For one month (I sync several times a day).
Nov 1st, entire calendar gone. So I looked a little closer. MS Office Access apparently installed a .dat file in the datebook folder with 108kb worth oaf data (the legitimate datebook.dat file is 1,308kb). Everytime I open Palm Desktop, that's the file that's altered. Erase it, it reappears everytime I re-open Palm DT,
I don't use MS Office Access, so I removed it. Open Palm DT, now a new 1kb UiPrefs.dat is created, even if I open DT by double clicking the real datebook.dat file. HELP! I must note that throughout this whole ordeal, the address book, memo, todo list were totally unaffected.
Vista Home Premium 32 bit. MS Office 2007.
Thank you!
Post relates to: Palm m500I haven't been able to hot sync with my handheld since I upgraded to Vista, so there is no backup on the handheld of any data. Grrrrrrr! I don't believe it. I thought I'd read posts about other people backing up their data.
Is there any "cheaters method" to create a backup copy by changing where the data file is saved, then changing it back, or something similar, so there are always two copies? I don't want this happening again, and I won't be able to upgrade my handheld for several months still. -
What are the data files in the Proxies folder?
In the iMovie Projects folder tree there are folders called Proxies. In that folder there is a folder called the name of the projects events folder, twice, with %20 for spaces and such. In that folder there are a large number of data files like 2010.data and such. What are these data files? In one case there are 861 of them and they take up 5.1 MB. Thanks.

An iMovie project is a bundle?
Yes. What appears in the Finder as a singel file is really a bundle of files.
But what are they?
I can't tell you exactly - but I'm sure there's data there that allows iMovie to undo things you've already done, references the event clips used in the movie, thumbnails, backups, transitions you've used - that kind of thing.
I deleted them on a junk project and so no ill effect, though I didn't check all the things you can do with a project.
Even so, I'd restrict that kind of experimentation to junk projects.
Regardless of whether it's safe to delete them, I'd like to know what they are.
Fair question. I wish I could tell you more.

Hi All,
We are working on the redistribution process of data files in SQL level. We knew that by doing the empty files options through shrink we could achieve it. But I would like to know, Is there any things which I need to consider in terms of number of data files(Any Formula to arrive a total number of data files for the better performance in SQL database level).
In my environment, the current database size is 420GB and its running with 24 data files, SAP advised us to minimize the data files because the data files are not in order (Like 1 data file having GB and some having 40GB and few having 90GB) - So, SAP recommended us to maintain the data file size as common and distribute the data equally among the files.
So, wondering the data file size and also number according to our environment (It would be kind if you suggest on it)
Database size :420GB
Database version : SQL 2005
CPU core : 4 cores running and its a Xeon processor

i am receiving the data through the rs232 in labview and i have to store the data in to the word or text file only if there is a change in the data. I have to scan the data continuasly. how can i do that. I was able to store the data into the text or word file but could not be able to do it. I am gettting the data from rs232 interms of 0 or 1. and i have to print it only if thereis a change in data from 0 to 1. if i use if-loop , each as much time there is 0 or 1 is there that much time the data gets printed. i dont know how to do this program please help me if anybody knows the answer
I have attatched the vi. Here in this it receives the data from rs232 as string and converted into binery. and indicated in led also normally if the data 1 comes then the led's will be off. suppose if 0 comes the corresponding data status is wrtten into the text file. But here the problem is the same data will be printed many number of times. so i have to make it like if there is a transition from 1 to o then only print it once. how to do it. I am doing this from few weeks please reply if you know the answer immediatly

Is there a way to change the Digitised Date for Mov files in Lightroom?
I am scanning some old photos. Unfortunately Programs such as Dropbox and OneDrive display Mov files by their digitised Date.
Consequently, My scanned photos are shown by the date that I scanned them. I can not seem to find anyway in LightRoom to change the Digitised Date so that they are shown on OneDrive/Dropbox in the correct order on my iPad.
Any help would be appreciated.Your subject line says "Mov files" (which are video files), but your message talks about scanning old photos. I'll address the old photos issue.
Because there are so many dates/times associated with photos, and because every program feels free to use its own names, it's critical to be pedantically precise about terminology. The date/time a photo was originally taken (when the shutter was pressed) is called Date/Time Original or Capture Date. The date/time a photo was transferred to digital media is called Date/Time Digitized (when the analog file was scanned or when the digital-camera shutter was pressed).
A good rule of hygiene is to ensure every photo has a Date/Time Original (capture date). Typically only digital archivists care about maintaining Date/Time Digitized. If you ensure that every photo has a Date/Time Original, then pretty much any modern app and Web site will order your photos correctly.
In LR, you set Date/Time Original using the Metadata > Edit Capture Time command. By default, LR won't write the capture time back to the file's metadata, so depending on how you are transferring photos to other programs, the capture time won't necessarily get transferred. So you either need to do Metadata > Save Metadata To File, or better, set the option Catalog Settings > Metadata > Automatically Write Changes Into XMP.
Unfortunately, LR's Edit Capture Time isn't very flexible with dealing with scanned photos in which the precise date/time is not known. So some people like to set an entire batch to, say, 1963/10/01 00:00:00, while others like to have each photo set in increasing increments of 1 second, so that programs will at least maintain the known relative ordering (which comes from the film or slide ordering). To do that, you'll need a third-party plugin, e.g. ExifMeta or CaptureTime To EXIF. -
How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?
Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.
