Wich file system is recomended for an usb key? [SOLVED]

Hi. I have an 8Gb USB Stick (USB key or pendrive).
I will use it to store my backups and ocassionaly to move some files between PCs. I don't use windows so i don't need niether want compatibility, so i don't want to use FAT32.
So, wich file system is recomended to use on an usb key??
Should i use ext3, reiserfs, xfs, jfs??? or maybe ext4???
Has any of them any implication with the lifetime of the usb?
Thanks

I use it for backups, so i wont need it. i have another one much smaller for that cases

I was afraid of something like that... thanks for the advice
so, ext2 would be the best option, wouldn't it?
Thanks to all for your help

Format Error : mkfs.ocfs2 1.2.7 file system too small for a journal

Hi All,
I am trying to implement Oracle 10g RAC on my laptop using vmware and openfiler software . But while executing the command
#mkfs.ocfs2 -b 4K -C 32K -N 4 -L oracrsfiles /dev/iscsi/crs11/part1
I am getting the error
Format Error : mkfs.ocfs2 1.2.7 file system too small for a journal
Please anybody can help me to resolve this problem.
Thanks in Advance.

How large is the device that you are formatting?
The default journal size depends on the type specified. If none specified,
then it assumes "mail" which sets the default journal per slot to 256M.
If database type, default is 64M.
Use "-T database" to specify database type, etc.
BTW, one can always override the defaults. Say "-J size=16M" to make
a smaller journal.
man mkfs.ocfs2 and the user's guide has more.

Unix shell: Environment variable works for file system but not for ASM path

We would like to switch from file system to ASM for data files of Oracle tablespaces. For the path of the data files, we have so far used environment variables, e.g.,
CREATE TABLESPACE BMA DATAFILE '${ORACLE_DB_DATA}/bma.dbf' SIZE 2M AUTOEXTEND ON;
This works just fine (from shell scripts, PL/SQL packages, etc.) if ORACLE_DB_DATA denotes a file system path, such as "/home/oracle", but doesn’t work if the environment variable denotes an ASM path like "\+DATA/rac/datafile". I assume that it has something to do with "+" being a special character in the shell. However, escaping "\+" didn’t work. I tried with both bash and ksh.
Oracle managed files (e.g., set DB_CREATE_FILE_DEST to +DATA/rac/datafile) would be an option. However, this would require changing quite a few scripts and programs. Therefore, I am looking for a solution with the environment variable. Any suggestions?
The example below is on a RAC Attack system (http://en.wikibooks.org/wiki/RAC_Attack_-OracleCluster_Database_at_Home). I get the same issues on Solaris/AIX/HP-UX on 11.2.0.3 also.
Thanks,
Martin

My revised understanding is that it is not a shell issue with replacing +, but an Oracle problem. It appears that Oracle first checks whether the path starts with a "+" or not. If it does not (file system), it performs the normal environment variable resolution. If it does start with a "+" (ASM case), Oracle does not perform environment variable resolution. Escaping, such as "\+" instead of "+" doesn't work either.
To be more specific regarding my use case: I need the substitution to work from SQL*Plus scripts started with @script, PL/SQL packages with execute immediate, and optionally entered interactively in SQL*Plus.
Thanks,
Martin

How to read some images from file system with webdynpro for abap?

Hi,experts,
I want to finish webdynpro for abap program to read some photos from file system. I may make MIMES in the webdynpro component and create photos in the MIMES, but my boss doesn't agree with me using this way. He wish me read these photos from file system.
How to read some images from file system with webdynpro for abap?
Thanks a lot!

Hello Tao,
The parameter
icm/HTTP/file_access_<xx>
may help you to access the pictures without any db-access.
The following two links may help you to understand the other possibilities as well.
The threads are covering BSP, but it should be useful for WebDynpro as well.

Question about a file system storage option for RAC on 10g

Hello everyone,
I am in the beginning of connecting our storage and switches, and building RAC on them but there is a little argument between our specialists.
We have two database servers(10g with OEL 5) to be clustered and two visible disk groups to each of those nodes. So question is can we choose only one disk group as a shared storage leaving the rest one as the redundant copy during database a creation window while installing the database. Because some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data.
Thank you for your help.

"some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data".
That statement is not true. Oracle has optional multiplexing for control files, redo logs, and archive logs but this is not enabled by default and Oracle will not automatically enable it. If you want redundancy of tables, indexes, temp, and undo you must provide this because Oracle does not offer it standard or as an option. You can achieve redundancy with RAID at the array level, or host based mirroring (like ASM redundancy groups or Linux mdadm). This can also depend on your file system because, I think, OCFS2 does not support host based mirroring (so you cannot use mdadm or lvm to mirror the storage if you are using OCFS2).
Redundancy is not required, but it is recommended if you are using hard disks because they are prone to failures. You can configure RAID 10 across all disks in the array and present this as one big LUN to the database server. If you have two storage arrays and you want to mirror the data across the two arrays, then present all of the devices as JBOD and use Linux mdadm to create your RAID group.
RAC requires shared storage. Maybe you have a NAS or SAN device, and you will present LUNs to the Oracle database servers. That is no problem. The problem is making those LUNs usable by Oracle RAC. When I used Oracle 10g RAC, I used the Linux raw device facility to manage these LUNs and make them ready for Oracle RAC. However, raw has been desupported. Today I would use either ASM or OCFS2. This has nothing to do with redundancy, this is just because you are using RAC.

Root File system is reporting that it's full [SOLVED]

My root file system is reporting as full, and I'd like some ideas on how to track the problem. I've tried a number of things like searching for the largest directory, searching for the largest file, and all that jazz. I'm obviously missing something. /dev/sda3 should be at 50%.
One note. The computer started what seemed like normal today. I converted my second hard drive to ext4, rebooted, and started to notice that things that needed the /tmp directory couldn't start. I made some quick space to get operational by removing 56M of stuff from pacman's cache, but that's a quick hack. I don't know if this is related or not. I am running testin

Thanks for the kind words MoonSwan.
This happened because of the way my system is set up. I have rsync making backups of /home and /etc to /backup on close. It turns out that rsync created the /backup directory instead of using the existing one. Why? Because /dev/sdb1 wasn't mounted when I restarted after the conversion. Doh!
no shame in that. i totally freaked out once when i was still in school because i couldn't find a paper that was due. turned out i had /home unmounted when i saved the file, but had /home mounted when i went looking for it.
it was hiding under the mounted filesystem the whole time!

Workflow for 16G Usb key flash backup?

I put all my data on a 16G usb flash drive. It has something like 10,000 files on it, organized neatly in a directory with about 10 folders at the root. I use this regularly on both a PC and a Mac. About 8GB contains data. I want to back it up weekly, but how? Ideally I would back it up to another USB key on occasion as well as a hard disk.
* A file copy just takes too long and invariably stops in the middle with an arcane message.
* The external drive I use to back up the Mac is a Time Machine, which uses an incremental approach not suited to the USB key.
* I am willing to do something simpleminded, like copy the USB contents to a folder on the Mac, archive it, then let Time Machine back it up. That seems inelegant.
* I would be happy to delete the files on the duplicate USB key and recopy the primary to it. But...
* A related problem is that just deleting files on the duplicate USB key doesn't actually reclaim the disk space. Emptying trash does not seem to work either.
What's the best way to keep the USB key backed up?
Thanks!

This probably is not a job for software like Time Machine that is designed to back up whole machines.
You can try using regular old file sync software between any two drives. On the Mac such utilities include ChronoSync, FoldersSynchronizer, ExecutiveSync, File Synchronization,etc. You will find a wide selection of them at versiontracker.com or macupdate.com. Typically you can load any two locations into one of these programs and tell it to just sync 'em up. I use one to sync between a project folder on my Mac and the same project folder on a USB drive or another Mac over the network.
I guess you'll want to pick a utility that preserves both Mac and PC file formats.

Shared file system recomended for OCR and voting Disk in 10g R2

Dear Friends,
For Oracle 10g R2 (10.2.0.5) 64 bit which shared file system is recomended for OCR and voting Disk (NFS / raw devices / OCFS2)
For Datafiles and FRA i planned to use ASM
Regards,

Hi,
If your using standard edition then you got no choice but raw devices

for ocfs2 you need to take extra care

File System Task - using a wildcard in variable

Hi,When using the "delete file" operation in the file system task I get an error stating that I have an incorrect path when using the wildcard symbol. Is there a way around this or do I have to spell out the whole name for each file in the
directiory. I cannot not use the "delete directory contents" operation because I have two sub directiories in my directory. I'm trying to use the following when I get the error
\\devbox\df\*.csv when I spell out whole name of the file it works. Any suggestions?
LISA86

this cant be done like this. Only possible if you put file system task in for each loop container and perform deletion one at at time.
http://technet.microsoft.com/en-us/library/ms140185.aspx
The File System task operates on a single file or directory. Therefore, this task does not support the use of wildcard characters to perform the same operation on multiple files. To have the File System task repeat an operation on multiple files or directories,
put the File System task in a Foreach Loop container, as described in the following steps:
Configure the Foreach Loop container On the Collection page of the Foreach Loop Editor, set the enumerator to
Foreach File Enumerator and enter the wildcard expression as the enumerator configuration for
Files. On the Variable Mappings page of the Foreach Loop Editor, map a variable that you want to use to pass the file names one at a time to the File System task.
Add and configure a File System task Add a File System task to the Foreach Loop container. On the
General page of the File System Task Editor, set the SourceVariable or
DestinationVariable property to the variable that you defined in the Foreach Loop container.

What is the minimum file system access needed to run ODI 10.1.3.4.0 client?

Hi ODI discussion folks,
I have a couple of questions from an Oracle partner that I'm trying to find a definitive answer for if possible. The partner is setting up ODI 10.1.3.4.0 for a customer who insists that the absolute minimum amount of access to the file system is granted due to corporate security policies.
I have checked the bundled ODI documentation but couldn't really find anything about file system permissions needed to run the ODI client. I was pointed towards the "Setting Up Security for an Integration Project — What to Consider" document but this does not mention a great deal about how much access to the file system is needed for the ODI client to function.
What the partner is asking is the following:
"1. What are the minimum file/folder permissions needed for the ODI client installation? I'm installing at xxxxx
and their machines have to be locked down as much as possible.
2. Say you have 3 users all wanting to run integrations etc and the Master and Work
repositories have been set up. An admin installs the ODI client but doesn't
create the connection to the Master repository. What are the minimum
file/folder permissions required on the client machine to:
a) create the connection to the repository
b) run any subsequent integrations?"
If anyone can advise on this then that would be much appreciated.
Regards

Hi Craig,
How are you?
Let me try to contribute a little....
1) The minimum requirement is for its own installation directory, there is no reason to have access to other directories unless if it is necessary to read files from some other directory at the client
2) Again only to its own install directory. The connection setting is recorded at \bin install directory. After that, all information are recorded at repository, there is no client work.
Be free to contact me by email or phone if you have any new doubt. You can get my email from my profile.
Does it respond your doubts?

Opinion on non-clustered file system to offload backups

3 node 11.2 rac using ASM on SAN.
All of the RMAN backups go to +FRA. Any node can initiate RMAN and create backups.
I want to offload the backups from +FRA to a filesystem. Our current backup system can only read cooked file systems.
This LUN also comes from the same SAN. It will have a file system, ext4. It will be visible to all 3 nodes and will be mounted to ONLY the first node. First node will be the one to copy from asm to this filesystem.
If first node is out of commission, I can mount the backup lun to one of the other remaining nodes.
Does this sound like a decent plan or should I go with a clustered file system?
Thanks for you opinions!

Have you looked at using ACFS? Create a very big diskgroup, then create an ACFS volume and finally an ACFS filesystem. create a path on all nodes on which the ACFS filesystem will be mounted.
Example: Using asmca do the following
mkdir /d01/FRA on all systems
DGFRA (4disks at 500G)
Create ACFS volume 1.8T
Create ACFS filesystem mount point of /d01/FRA
set your db_recovery_file_dest=/d01/FRA scope=both sid='*'
Now any node can backup to this FRA location AND any node can copy files to tape or where ever...
This is "supported" as of 11.2.0.3 ( I have used it on 11.2.0.1 and 11.2.0.2 for testing)

Database storage vs. File system

Hi,
We'll be setting up a new Oracle UCM 10g* environment in a production scenario - we have access to high-speed SAN for file storage, but we can also use an Oracle 11g database for file storage (using the File Store Provider) - the database's tablespace files will anyway be stored on the SAN. We're not quite sure which way to go - assuming we have complete ha/dr for both SAN and database solutions, which way is the best?
I'm also aware that if we don't select the webless option we'll anyway need a similar amount of storage on the file-system as the weblayout will contain a copy (or a web-rendition) of the checked in file - we could create a webless ucm, with inbound refinery only creating files in weblayout.
Any input on the matter would be appreciated.
*11g not chosen due to WebLogic licencing requirements for our client - anyone know if 11g will ever be released standalone?
EDIT - re: 11g licensing - sorry about that i misunderstood the licensing issue of our client.
Edited by: Etienne Azzopardi on 04-Feb-2011 13:44

Sorry, but I will start my reaction from the last point:
*11g not chosen due to WebLogic licencing requirements for our client - anyone know if 11g will ever be released standalone?What do you mean? UCM license contains a restricted license of Weblogic EE for the purpose of hosting UCM. In other words, WLS is there for free (only it cannot host anything else). 11g will never be standalone - it will only support other application servers, namely, Websphere and JBoss (it follows the logic for other non-Oracle middleware products).
File system vs. database - there's been a couple of posts on this topic.
In a nutshell:
- with regard to the speed: unless you have really a lot of items (millions a month at least, maybe even millions a day), file system will be slightly faster or equal
- in Oracle DB 11.2 or higher you can use SecureFiles, which can effectively work with unstructured content. It can squeeze the disk space needed for storage, speed up operations (checkins, but also e.g. backups)
- with DB you will effectively have one system to manage - well, UCM still requires file system (shared storage for clusters), because some operations like conversions cannot run on the content in the database
- DB gives you further options like partitioning, hierarchical storage management, advanced security, etc. Your SAN storage can have some of these too.

How to restore file system of the previous backup from OSB using webtool?

Dear all,
I have some problem regarding to the file system restoration.
For example, I have backed up some files yesterday and today those files have been made change.
So tomorrow I am planning to restore the files from the yesterday backup (the original files before made changes) to other host for testing the data.
Is it possible to do that, since when i restore i can see only the latest ones and search options during restoration are not working well (as date, date range,.....) ?
Your reply to me is very important.
Thanks and regards,
Rasmey

There is no recovery partition on drives which haven't had 10.7 or 10.8 installed. You need to use a Mac OS X install DVD to restore the backup.
