UNIX File System?

I was able in the past to format a disk with UNIX File System and read and write to it using Disk Utility in OS X Tiger. Now, my new Leopard machine does not show that option. What happened to that? How do I get it back?
Thanks,
John

I'm pretty sure UFS support is totally gonzo in leopard. you certainly [can not install Leopard|http://docs.info.apple.com/article.html?artnum=306516] on UFS formatted drives.

Uploaded Files stored in Oracle 10G database or in Unix File system

Hey All,
I am trying to understand best practices on storing uploaded files. Should you store within the database itself (this is the current method we are using by leveraging BLOB storage) or use a BFILE locator to use the files system storage (we have our DB's on UNIX) . . .or is there another method I should be entertaining? I have read arguments on both sides of this question. I wanted to see what answers forum readers could provide!! I understand there are quite a few factors but the situation I am in is as follows:
1) Storing text and pdf documents.
2) File sizes range from a few Kb to up to 15MB in size
3) uploaded files can be deleted and updated / replaced quite frequently
Right now we have an Oracle stored procedure that is uploading the files binary data into a BLOB column on our table. We have no real "performance" problems with this method but are entertaining the idea of using the UNIX file system for storage instead of the database.
Thanks for the insight!!

Anthony,
First word you must learn here in this forum is RESPECT.
If you require any further explanation, just say so.
BLOB compared with BFILE
Security:
BFILEs are inherently insecure, as insecure as your operating system (OS).
Features:
BFILEs are not writable from typical database APIs whereas BLOBs are.
One of the most important features is that BLOBs can participate in transactions and are recoverable. Not so for BFILEs.
Performance:
Roughly the same.
Upping the size of your buffer cache can make a BIG improvement in BLOB performance.
BLOBs can be configured to exist in Oracle's cache which should make repeated/multiple reads faster.
Piece wise/non-sequential access of a BLOB is known to be faster than a that of a BFILE.
Manageability:
Only the BFILE locator is stored in an Oracle BACKUP. One needs to do a separate backup to save the OS file that the BFILE locator points to. The BLOB data is backed up along with the rest of the database data.
Storage:
The amount of table space required to store file data in a BLOB will be larger than that of the file itself due to LOB index which is the reason for better BLOB performance for piece wise random access of the BLOB value.

External Tables to Unix File System 10G R2

Can anyone help with setting up an external table that reads a flat file from a Unix File system.
I have sampled a file ok and created an external table and deployed it to the database ok but it can find the link through to the unix file system to read the file.
I created the location as an FTP type and have referenced the path to the relevant directory /oracle02/app/OWB_files when creating the location. I have placed the relevant named file in the directory but when i try to look at the table in TOAD i get the following errors
ORA-29913 error in executing ODCIEXTTABLEOPEN callout
ORA-29400 data cartridge error
KUP-04040 files 121123_PENS.txt in MLCC_FILES_LOCATION_0 not found
Does anyone have a step by step guide for creating these and am i doing some thing wrong. Is choosing the FTP type in the location correct and is the path specified correctly. I can see much information on thisin the manual!
Your assistance would be appreciated

HI,
You make sure that, the path should be shared one. We can do this using samba server.

IPod formatted to UNIX File System (UFS)

Hello all, I had an old 15G iPod (the generation with the 4 button above the wheel) and I decided to reformat it and use it as a firewire drive, it's not used for music anymore. Anyway, I was about half way through the format and I noticed I had accidently sellected UNIX File System (UFS) instead of Mac OS Extended. Well I let lt finish and thought I'd just reformat it again to Mac OS Extended, only now the iPods not even being recognized by OSX? I looked in Disk Utility and nothing there either. iPod restore does nothing either, just says connect an iPod. There's an Apple on the screen and that's it? What gives? Will I be able to get this thing running again?

Thanks but no thanks! I got it going using info at this link:
http://ipodlinux.org/Installation
Got it in Disk Mode!!!

Open API App (Windows based) fails to open FMB on Unix file system

My Open API, Windows based app, can successfully open and 'get' properties of FMBs stored in the Windows file system. However, it fails to load the FMB when the FMB resides on a networked Unix server. The same FMBs on Unix can be opened by the Windows based FormBuilder (over the network). I can copy the FMB down to Windows and without re-compiling the FMB, my Open API app can 'load' the FMB and 'get' all the properties. What suggestions can you give for debugging / resolving this? I need to be able to 'Load' the FMBs (through the Open API), that reside in the Unix file system, from Windows.

Generally, this is why we will tell you that accessing net shares is not supported and in places where it might even be supported, we would still suggest that it is not recommended. Accessing via net shares (especially through Windows) is often problematic. There are various performance and connectivity issues that, unfortunately fool you into believing that the product you are using is flawed when the problem is really a connection issue with the share.
In your case, because you are not exactly using an Oracle product (initially), Oracle can't offer much anyway, but I would recommend against using shares whenever possible. If you need to access a file, copy it locally first, perform whatever task on it, then return the updated file to its origin. This method protects you from things like net failure and instability as well as the performance issues associated with accessing files remotely.

Download PDF spool to unix file system

Does anyone know how to programatically download a PDF document spool to the unix file system?
I am trying to find a method to send PDF documents that have gone to spool to a unix file system. If anyone had any ideas on how to do this, please let me know.
Thanks.

Hi,
For this define a logical file while using transaction FILE.
In your code you will get the complete path of the file while using FM FILE_GET_NAME.
Then download your PDF while using instruction
OPEN DATASET...
TRANSFERT ...
Hope this help you .

Java script in HTMLDB to check if file exists in Unix file system

How do I use javascript to check if file is exists in Unix file system. I would like to dispaly the columns only if file is exists.

Hello,
This is one of those features that the manuals do not cover.
How to use and build AJAX features could be a whole book all by itself, and it's not really HTML DB specific feature even though we have built some hooks in application and javascript to make it easier.
Take a look at this thread
Netflix: Nice UI ideas
and I've built some examples here

Or just search the forums for AJAX or XMLHTTP

Essbase unix file system best practice

Is there such thing in essbase as storing files in different file system to avoid i/o contention? Like for example in Oracle, it is best practice to store index files and data files indifferent location to avoid i/o contention. If everything in essbase server is stored under one file directory structure as it is now, then the unix team is afraid that there may run into performance issue. Can you please share your thought?
Thanks

In an environment with many users (200+) or those with planning apps where users can run large long-running rules I would recommend you separate the application on separate volume groups if possible, each volume group having multiple spindles available.
The alternative to planning for load up front would be to analyze the load during peak times -- although I've had mixed results in getting the server/disk SME's to assist in these kind of efforts.
Some more advanced things to worry about is on journaling filesystems where they share a common cache for all disks within a VG.

How to read XML from UNIX file system

Hi,
I have this code with read a xml file from windows:
Document doc = builder.build(new File(C:\\mywork\\src\\Contacts.xml));
But how can I read the same file from UNIX? (The file is located in "\tmp\Contacts.xml")
Thanks
Kenny

Hi,

Document doc = builder.build(new
File(C:\\mywork\\src\\Contacts.xml));
But how can I read the same file from UNIX? (The file

Thanks
KennyNo, the file is really located in "/tmp/Contacts.xml". You would writeDocument doc = builder.build(new File("/tmp/Contacts.xml"));Also, your original code would need quotes around the filename too.

Displaying pdf from file system in OA framework pages

Hi,
If anyone could help me with this I would be very grateful.
We have a number of pdfs containing sensitive information, held on our Unix file system in directories not publicly available.
I want to create an OA framework page which takes the name of a pdf as a parameter and displays the content of that pdf on the user's browser. I cannot simply do a redirect because the pdfs are not publicly available.
I've found some sample java code that allows you to set InputStream and OutputStream and read the content of the file. However, I cannot see how to redirect the output stream to the browser. Of course, this may be entirely the wrong approach.
Can anyone suggest anything or point me to some documentation that might help?
Many thanks,
Mike Thorn.

Hi Shiv,
Thanks for responding. I'm not sure whether I've explained my problem properly, so I've included a code snipet below.
I've got my head around how to stream the contents of a file to an output string but cannot see how to bolt this into the controller region for an OA framework page. In the code below, you'll see I have a dofile which reads from my D: drive and streams to the System.out. I'm calling this from the processRequest for the page controller but do not understand how to get the output stream into the OAHTMLWebBean (my inclusion of Google works just fine).
All this Java is rather new to me I'm afraid.
public static void dofile()
try{
OutputStream outStream = System.out;
String fileName= (String)"index.htm";
String filePath = "D:\\Jdeveloper\\jdevdoc\\";
File f = new File(filePath, fileName);
String fileType = fileName.substring(fileName.indexOf(".")+1,fileName.length());
byte[] buf = new byte[8192];
FileInputStream inStream = new FileInputStream(f);
int sizeRead = 0;
while ((sizeRead = inStream.read(buf, 0, buf.length)) > 0) {
outStream.write(buf, 0, sizeRead);
inStream.close();
outStream.close();
     catch (Exception e) {
          System.err.println(e);
          System.err.println("dofile error");
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
dofile(); //but how do I egt the output to the OAHTMLWebBean?
// the following works fine to include Google
OAHTMLWebBean outRegion = (OAHTMLWebBean)createWebBean(pageContext, HTML_WEB_BEAN, null, "IFRAME");
outRegion.setHTMLAttributeValue("src","http://www.google.co.uk");
outRegion.setHTMLAttributeValue("width", "100%");
outRegion.setHTMLAttributeValue("height", "60%");
outRegion.setHTMLAttributeValue("title","My title");
outRegion.setHTMLAttributeValue("name", "My name");
pageContext.getPageLayoutBean().addIndexedChild(outRegion);
Many thanks again for any help you can offer this Java virgin,

File System repository manager

Hi All,
I am working on configuring a File System Repository Manager. I followed the documentation at
http://help.sap.com/saphelp_nw70/helpdata/EN/e3/92322ab24e11d5993800508b6b8b11/content.htm
and
https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/284
I made all the configurations and also restarted the portal still do not see the repository in the KM content under root. We are on Netweaver Portal 7.0 on AIX 5.3/DB6, Shared drive is on Win 2003 OS.
Here are the some details on the configurations I made:
Network Path:
jCIFS Protocol: Active
Description: Documents on Shared Drive
Network path:
<IP Address>\public\temporary
password: ***********
USer: Domain\User
File System Repository:
Description: Documents on Shared Drive
Prefix: /abcdef
Root Directory: //<IP Address>/public/temporary/FileShare
Security Manager:AclSecurityManager
ACL Manager Cache: ca_rsrc_acl
Read Only: Not Active
Please advice - thanks -sm
Edited by: sm on Oct 24, 2008 4:34 PM
Note: EP and Share Drive are on the same domain.

Hello sm,
You can monotor your repository manager cofiguration, whther it has been activated or not.
It should show in green symbol if it has been correctly configured and active.
Goto system Admin>monitoring>KM>Component monitor>Repository managers-->Check ur repository.... Green color indicate is working fine...
Red color indicate error...
you can check your configuration for the repository.
Example configuration of a UNIX file system repository manager:
Name                = fs_rep_unix
Localroot           = /usr/company/share
Prefix              = /company-share-unix
Read Only           = deactivated
Send Events         = activated
Repository Services = properties, rating
ACL Manager Cache   = ca_rsrc_acl
Security Manager    = AclSecurityManager
You can check your Local root i.e. your Root directory. The format should be correct as given in the example.
Don't foget to appreciate, if helpful!!!

Checking /Viewing Unix file permissions

Is there a way for me to check file permissions (In Java) under unix, without having to call a system dependent function. (ie Runtime.getRuntime(); run.exec(....))
Any help would be greatly appreicated.
Curtney

Thank you for replying.
You are correct, I can detect ile permissions by using these functions, more specifically whether the current running application is able to read/write to a particular file.
However, I am interest in knowing the file permissions /attributes
for user and group on the unix file system despite whether the current running application can read/write to a particular file.
ie,
-rw-rw--r-- 1 username groupname size date .... filename
I have searched and I believe, currently, there is not a class/member function that accomplishes the above.
Again, Thanks for responding.
Curtney

RAW DEVICE와 FILE SYSTEM 간에 오라클 데이터화일 이동하기

제품 : ORACLE SERVER
작성날짜 : 1999-11-30
RAW DEVICE와 FILE SYSTEM 간에 오라클 데이터화일 이동하기
======================================================
유닉스 명령이 dd를 이용하여 오라클 데이터화일을 Unix File System과 Raw
Device 간에 이동할 수 있으나, 플랫폼 별 Raw Device의 특성으로 인하여 주의할
점이 있다. 만일 잘못된 이동으로 인하여 데이터베이스가 기동하지 못하면,
ORA-7366 (sfifi: invalid file, file does not have valid header block.)
에러가 발생할 수 있다.
예를 들어 Digital unix의 경우는 raw device에 64k OS 헤더가 필요하므로 dd
명령어 옵션 중 iseek와 oseek를 활용하여야 한다.
다음은 예제를 통하여 데이터화일을 Raw Device에서 Unix File System으로
이동하는 절차이다.
(운영 현황)
- 현재의 위치: /dev/rdsk/c0t15d0s7
- 이동할 위치: /oracle/file/system.dbf
- 화일의 크기: 488636416 bytes <--- V$DATAFILE.BYTES column 값!
- DB_BLOCK_SIZE: 2048 bytes
(준비 단계)
1. Oracle 블럭 수 계산:
BYTES / DB_BLOCK_SIZE = 488636416 / 2048 = 238592 (블럭)
2. O/S file header 블럭 추가:
238592 + 1 = 238593 (블럭)
: "ls -l /oracle/file/system.dbf" 명령으로 확인 가능하며, O/S file
header는 1블럭으로 항상 일정함.
3. Raw Device OS header 블럭 계산:
64K / DB_BLOCK_SIZE = 65536 / 2048 = 32 (블럭)
: 사용할 dd 명령어 중 블럭의 크기를 DB_BLOCK_SIZE(2048바이트)로 할
예정이므로 2048로 나누어야 함.
(명령어 형식)
$ dd if=<raw device> of=<UFS file> bs=<oracle blocksize>
iseek=<blocks to skip> count=<total count>
(명령어 수행 절차)
(1) SVRMGR> STARTUP MOUNT
(2) SVRMGR> !dd if=/dev/rdsk/c0t15d0s7 of=/oracle/file/system.dbf
bs=2048 iseek=32 count=238593
(3) SVRMGR> ALTER DATABASE RENAME FILE '/dev/rdsk/c0t15d0s7' TO
'/oracle/file/system.dbf';
(4) SVRMGR> ALTER DATABASE OPEN;
========================================================================
반대로 Unix File System에서 Raw Device로 이동하는 명령어 형식은 아래와 같다.
(명령어 형식)
$ dd if=<UFS file> of=<raw device> bs=<oracle blocksize> \
oseek=<blocks to skip> count=<total count>
유사한 방식으로 데이타 화일 뿐 아니라 리두 로그 화일도 이동할 수 있다.
[주의] Raw Device의 블럭 헤더의 크기는 OS마다 다를 수 있으므로 플랫폼
벤더사에 미리 확인한 후 작업하여야 한다.
