Hi All,
i need a requirement i have a directory . inside i have lot of .dat files. i want to create a file using UTL_FILE concept. but before creating the file i have to check the directory
the file name already exists or not???
How to do that in UTL_FILE???
Can anyone suggest me in this??
Thanks in Advance
Cheers,
Shan

DECLARE
vInHandle utl_file.file_type;
BEGIN
vInHandle := utl_file.fopen('ORALOAD', 'test.txt', 'R');
IF utl_file.is_open(vInHandle) THEN
dbms_output.put_line('The File exists');
Else
dbms_output.put_line('The File dosen't exists');
END IF;
END fopen;Note that you must declare in database directory object called "ORALOAD":
CREATE OR REPLACE DIRECTORY ORALOAD AS '/usr/users/oracle/';

Open PDF's in new window in document library when using "Find a file" search

I need to be able to open PDF's in a new window from a document library when using the "Find a file" search built into the document library "All documents" view. I currently have the following javascript on the page:
_spBodyOnLoadFunctionNames.push("setTargetBlank()");
function setTargetBlank()
{ $("a[href$='.pdf']").removeAttr('onclick').attr("target", "_blank");
This works great when going to the document library and navigating through the folders then clicking on a link.
The problem is when someone goes to the document library then uses the "Find a file" search and then they click on a link. The "Find a file" search does not do a postback (reload) of the page, therefore my javascript to find the PDF links
and make them open in a new window does not run for the links on the page.
I have read the following article but this does not seem to offer a solution that will work in this situation for SharePoint 2013 (Office 365): http://social.technet.microsoft.com/Forums/sharepoint/en-US/7ad3224c-3165-47ae-95bc-4f3928e2f9a8/opening-document-library-pdf-in-a-new-window-sharepoint-2013?forum=sharepointgeneral
I suppose the idea solution would be to somehow tap into the event that is fired when using "Find a file" search to run my javascript and update the links for the search results.
Can anyone offer any solutions to this issue?

Hi,
According to your description, my understanding is that you want to open PDF files in a new window from a document library when using the "Find a file" search.
As you said, the "Find a file" search does not do a postback (reload) of the page, therefore JavaScript to find the PDF links and make them open in a new window does not run for the links on the page.
I recommend to use JS link to achieve the goal. Create a JavaScript override file and upload the JavaScript file to the Master Page Gallery, and then set the JS Link property of the document library web part to point to the JavaScript file.
Here are some links about the JS link in SharePoint 2013 for you to take a look:

How can i create excel sheet with multiple tabs using utl file?

how can i create excel sheet with multiple tabs using utl file?

Re: How to Generating Excel workbook with multiple worksheets

Is there a way on maxdb to force netbackup to use different initSID.utl fil

(This thread refers to a question that was posted to a blog and where the proper location to handle it is this forum)
Is there a way on maxdb to force netbackup to use different initSID.utl files ? I have try to do it with different bsi.env file . But if i start the backup it keep on asking for the default bsi.env file in /sapdb/data/wrk/SID directory . I have set the variable BSI.ENV to the new file but it looks like it ignore it. Its on a sun solaris operating system
Due to security reasons the DBM server process does no longer inherit environment variables from its caller, e.g. dbmcli.
see PTS 1155045, as especially in the area of external backup tools inheriting environment settings seem to be rather common.
Idea is to add BSI_ENV to the dbm.cfg file with a command like:
dbmcli -d ... -u ... dbm_configset BSI_ENV
For further information please refer to this documentation section
or for Backint also here
Best regards
Jörg

Hi Jörg,
hmmm. I'd guess there are some problem with for which user the environment variables have been defined...
Anyhow, usually it's easier not to use the environment variables but to provide the dbm-server it's own runtime variables via dbm_configset.
Check the old thread archive_stage and archive_stage_repeat to different NSR_POOLs for an example application of this.

Lars

Bug in Multi-File Search and Replace in RH6?

I'm using the 6.0 trial, and one thing I want to be able to
do is to replace the variables I put in using JavaScript with the
new feature variables in 6.0. So, I went in to multi-file search
and replace, and searched for:
<script
language=JavaScript>document.write(varProduct)</script>
I copied this code directly from a topic, and pasted it into
the Search tool.
I don't even care whether I can successfully copy the code
from my new variable for use as the replacement text; I'd be happy
if the multi-file search would simply find all occurrences of my
original code so I don't miss any during conversion to 6.0.
It keeps coming up as not found, and this concerns me
greatly. Has anyone else experienced this? Is it a known bug? Does
anyone have a workaround?
Thanks!

Hi robowriter
I'm assuming you are using the wondrous little applet known
as Multi-File Find and Replace.
Unfortunately, this little beastie is like a cat. It
frequently has a fussy tummy and loves to hork up furballs. Well,
not exactly. Really what it does is fail to properly handle
anything with a line break. So you need a tool that does do this.
Fortunately, one exists! It is called FAR (Find And Replace). Oddly
enough, it was also written by a fellow Microsoft Help MVP named
Rob Chandler. (Rob lives in Australia)
You can download a trial version of FAR from the FAR page.

Utl file in report

hai all,
I have to develop a report using utl file.
Like when the report is given a parameter some four columns are displayed, at the same time i want to write the data in a text file in the server path /usr/tmp.
used formula column for utl file open , putline etc.
While running i am getting the error
REP-1401:'cf_1formula', Fatal PL/SQL error occured.
ORA-00600:internal error code , argument :[kghal02],[oxo],[],[],[],[],[]
can anyone suggest me a solution for this or there is any other solution for using utl file in oracle reports.
I am in urgent need of it.
Thamks and regards,
aaditya

Make sure that the directory you use with UTL_FILE is writable. For example, if you use /abc/xyz, then both directories (abc and xyz) should be writable.

Cretaion of UTL.File in Oracle 10G and directory entry in Ora.ini file

Hi,
Kindly advise me if:
(!) we can create a directory and log file in this directory on some other server instead of creating it in the file system of the server where the Oracle 10G database is residing?
Created directory in Oracle using create or replace directory command.
My package will be creating a log file using UTL.File in the above directory.
I want to create this directory on some other server to save my log file/s. Is this possible?
(2) Also, let me know in Oracle 10G, do we need to add the directory entry (mention above in #1) in the Ora.ini file on the Oracle 10G server?

Hi,
1) utl_dir are different from directory object
2) you cannot create directory on remote server and there is no need to write directory entry on oracle init file (not ini..)

Server 2008r2 and windows 7 pro slow to no networkshare file searching and file access (green progress bar)

we are running a windows server 2008r2 sp1 domain controller and a 3com gigabit switch to which 7 windows 7 pro computers are connected. We are only using the windows server to distribute a few printers and as a network share (z drive).
we are storing all files (word documents only) centrally on the server (z share), and files are accessed and written to the z share.
Problem is that file access from the z share on the windows 7 client computers is at best buggy. we are able to browse the z-share, but as soon as we want to search the z-share for files (f.i. use file explorer with "content: memorandum") the green
progress bar shows and no search is performed. something like alphabetically sorting a directory on map/file name on the z-share also shows a green bar with no sorting. manually going to the files works.
One thing i noticed, sometimes not all files that one user created and stored on the server is visible and can be found by another user. I prefer to disable all offline file caching setting, because that feature is not used. no files should be made accessible
offline. i don't know where to change that on the server side.
I am reluctant to experiment on the server end (2008r2 sp1), so i tried a few suggested solutions on the client end (windows 7 client)
I tried disabling offline file caching
i tried properties (z share) ==> advanced and map optimizing and several options there
i tried disabling the smbv2 protocol and disabling the smbv1 protocol (using
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi command etc. posted by microsoft)
i tried disabling windows defender
i tried accessing the z share via ip and server name (the share is mapped via its servername, e.g. dennis-dc1\share). still the same
file searching on the clients c drive ('own harddrive') works much better, file searching on the server also works.
any suggestions or solutions that i can test on the client side, as mentioned i am reluctant to change something on the server side. if a solutions works, i prefer to change it on the server side.

Hi,
The issue could be due to windows indexing service taking long time in sorting and searching in mapped drives. Please try the steps belwo to disable windows indexing service or search service on the windows 7 client to resolve the issue.
You can click on Start and select Control Panel, click on
Programs and Features, go into the Turn Windows Features on or off section Scroll down the list and uncheck the box next to Indexing Service or Windows Search.

Mandy

Getting INVALID_OPERATION while using UTL file

Hi,
I have a procedure which makes different UTL files i.e data file, error file and log file for a Purchase order. These 3 sets of files are made for every purchase order.
So suppose in a cursor i find that there are 10 Purchase orders to process, then it should create 30 UTL files 10 sets of 3 files.
But when i run this procedure, after processing 3 PO's i.e after creating 9 files i get INVALID_OPERATION error.
So lets say i have 10 PO's 1 to 10 , i run for first time PO 1,2 and 3 utl files are created and then i get error. Then when i run it again processes PO number 4 to 6 and then again error...
So i want to know is there any restriction on number of UTL files you can create in a single procedure. i want urgent help, appreciate ur quick replies on this matter.
thanks,
Dipin

Hi,
There could be several reasons for this...
1. In inti ora file, what utl file directory was specified? is it 'C:\PLXML\DBDOM'? if not check.
2. Do u have C:\PLXML\DBDOM\Testfile.txt in your directory?
3. If you have above file in that directory and you have opened that file for writing purpose, close that.
Ur program looks ok. Also, dbms_output.put_line will display 255 charcters only(at least in 7.3).

Problem with UTL FILE COPY

Hi,
I am facing one small problem in UTL FILE COPY package. We have an automated scheduled batch process. As a daily batch process it moves the files from one folder to other. During movement, it first copies the file from source folder to destination folder using FILE COPY package and then removes the file using FILE REMOVE package from the source folder.
Few cases are found that the file when files are copied they are copied as 0 bytes in destination folder but the source file had 1 MB file size. The interesting part is I am unable to replicate the issue. Means when i try to run once again the package its working properly and files are copied with correct size. This kind is issue is occuring very rarely though as once in month but the question is why FILE_COPY package is not working properly sometimes.. I am unable to understand.
Thanks a lot for going through this. Any suggestions.
Regards,
Ashish

Anyhow make sure that the copy will start after the full generation of files.
You can think like a spool file generation with huge data. In that case initially spool file available with 0 byte only. After finish of query only it shows its actual size.

Problem with utl file

Hi to all,

I dont understand the UTL_FILE package is granted to PUBLIC role by default.
In sys user the handler is throwing the error perfectly that invalid file operation. then why this is not occuring with other users.
Please let me know why this is happening
Thanks and Regards,
Vijay

Hi Vijay,
There are two problems here...
The first is that your user doesn't appear to have execute privs on the procedure. As you say, it is usually granted to public, but it doesn't look like it is for you. Check the privileges with:
select *
from dba_tab_privs
where table_name like 'UTL_FILE'
This will list who has permissions on the package. If you get nothing, grant execute to either public or to your user:
grant execute on sys.utl_file to <user/public>;
The second problem is a syntax error on line 5 of your procedure. Remove the ',256' bit - it shouldn't be there.
F1 := UTL_FILE.FOPEN('READ_FLAT_FILE','HMI PO','R');

Issue with utl file

Hi,
I am using UTL file to export records from table with fixed delimiter to a text file.
It works fine except that I see an additional character @ at the end of the file in the last line.
Can anyone let me know why are we getting this and how can we delete it..
Thaks in advance..

I assume, as you are saying you can see the file ok in notepad/wordpad that you are creating a text file.
So a) what are you using to view the file in unix and b) how did you transfer the file to unix?
When you transfer files from Windows/DOS based operating systems to unix based operating systems you have to be aware that Windows uses a CR/LF pair of characters to terminate a line (a 'newline') and unix just uses a single LF character (character 10 in the ascii table) to terminate a line. So when you transfer the files you need to convert the CR/LF pairs into just LF characters.
Typically this is done if you transfer the files using FTP and specify the 'mode' to be ASCII rather than BINARY.
c:\>ftp testserver
Connected to testserver.mycompany.com.
220 sunny2 FTP server ready.
User (testserver.mycompany.com:(none)): myuser
331 Password required for myuser.
Password:
230 User myuser logged in.
ftp> ascii
200 Type set to A.
ftp>
This tells the FTP software that you are transferring text files and that it needs to convert newline characters, if necessary, when transferring between Windows and Unix operating systems.
And for reference, if it's not a text file, then you must transfer in BINARY mode to ensure the files remain byte for byte the same...
ftp> bin
200 Type set to I.
ftp>
If you don't transfer text files, between different operating systems, in ASCII mode, then those files will either be missing characters or have additional characters that aren't wanted.

File search problems in Leopard

I MUCH preferred the older (pre-leopard) finder file search application(NOT spotlight). I was able to type what I was looking for and manually select the drives and servers I wanted searched in the finder window. The results came in, broken down by kind (image, document, pdf, folder) in icon driven sub-categories. Spotlight and the clumsy new search application are a MAJOR setback for me. This is the first bad move I have had to call Apple on.

You can only select the whole computer, or ONE and only one specific location to search (this is a reduction in functionality from the implementation of Spotlight in Tiger). Thus if I wanted to search my Data drive only, not my startup or backup drive, I would navigate in the Finder to the Data drive, then hit Command-F, then click on "Data" rather than the default "This Mac" (which is always selected, which is ridiculous--when you bring up search with a Command-F you want to search in that place, if you wanted to search everywhere you would use the Spotlight menu bar function). The nearest you can come to grouping things is to put the results window into List view (Command-2 or select from List from the View option in the Finder window's toolbar), then click the Kind column. You might find my little essay on Leopard's Spotlight helpful:
http://www.pinkmutant.com/articles/Leopard/leospot.html
You might also wish to tell Apple about how you feel:

The more complaints they receive, the more likely things will improve.

How to write generic procedure of utl exception handling ?
please advise.
create or replace procedure sp_utl_exception
begin
when utl_file.invalid_path then
raise_application_error(-20001,
'INVALID_PATH: File location or filename was invalid.');
when utl_file.invalid_mode then
raise_application_error(-20002,
'INVALID_MODE: The open_mode parameter in FOPEN was invalid.');
when utl_file.invalid_filehandle then
raise_application_error(-20002,
'INVALID_FILEHANDLE: The file handle was invalid.');
when utl_file.invalid_operation then
raise_application_error(-20003,
'INVALID_OPERATION: The file could not be opened or operated on as requested.');
when utl_file.read_error then
raise_application_error(-20004,
'READ_ERROR: An operating system error occurred during the read operation.');
when utl_file.write_error then
raise_application_error(-20005,
'WRITE_ERROR: An operating system error occurred during the write operation.');
when utl_file.internal_error then
raise_application_error(-20006,
'INTERNAL_ERROR: An unspecified error in PL/SQL.');
when utl_file.invalid_filename then
raise_application_error(-20010, 'The filename parameter is invalid.');
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(fileHandler ) THEN
UTL_FILE.FCLOSE (fileHandler );
END IF;

end;

Very poor implementation.
a) Absolutely no need for that exception handler in there. It should be removed.
b) As it's a procedure for logging exceptions relating to UTL_FILE, it would seem error prone to be logging the errors with UTL_FILE. For example, what is it supposed to do if the exception is raised because of lack of disk space in those file locations? How is it going to write out the exception with the disk full? Also, if the exception handler is used by multiple processes, then only 1 process at a time can access the log file to write it's exceptions, so it doesn't scale well. Better logging is done by having an autonomous transaction procedure that writes log/trace messages to dedicated table(s). That also means that the logs etc. can be viewed, as appropriate, from any client using SQL (either manually or through a application written to view logs etc.), rather than requiring physical/remote access to the server o/s to go and view the contents of the file, which in itself could lock the file and prevent any process from writing further logs whilst it's being used.
