Want to be able to mount file systems in my computers at home

Hi,
I have 2 apple computers , a mac pro and an ibook and I want to be able to mount the file system from one to the other to transfer files. What software do I need to do this?
I suppose I could use an FTP server just to transfer files is there one for free?
Or if I actually want to mount the file system , what do I need?
thanks

As sig said, firewire is a really good way to do this. It is one of the easiest and fastest and most painless ways to do this.
If it is not so convenient for you to tether up one computer to the other via firewire, if the computers are on the same home network, enable personal file sharing (Sys Prefs > Sharing > Services) in at least one of them. Then you should see it on the other computer when you do ⇧⌘k in the Finder. Double-click on it and its icon should mount on your desktop. Open it, then drag and drop the files. If on the same home network and you enable ftp or remote login (Sys Prefs > Sharing > Services again), you can do it from the command line, no extra software required.
If they are not on the same network, e.g., one is at work and the other is at home, this can still be done fairly easily and fairly painlessly in a hack-proof manner by tunneling your file sharing port through secure shell. If you want to do it that way, that's a bit more involved to initially set up, but really not difficult to do. Post back if you want help doing that.

RMAN to Disk (shared mounted file system) then secure backup to Tape

Hi
This is a little away from the norm and I am new to Oracle secure Backup.
We have several databases on physically separate servers, all backup to a central disk (a ZFS shared file-system).
We have a media server also with the same mounted file-system so it can see all of the RMAN backups there.
Secure backup is installed on the media server and is configured as such.
The question I have is I need to backup the file system to tape where all the RMAN backups live, I have configured the data set but I get file permission errors for each of the RMAN backup files in the directory.
I have tried to change these permissions but to no avail (assuming it is just a read write access change that is needed - but this may be a problem in the long run). What is the general process for backup of already created RMAN backups sat in a shared area? I know its not the norm to do to disk then to tape backups but can this be done? I would have installed Secure backup client on each server and managed the whole backup through secure backup but this is not possible I must do the to tape from the file system, any advise and guidance on this would be much appreciated.
Kind regards
Vicky

You can easily accomplish a very streamlined D2D2T strategy! RMAN backup to disk...then backup that disk to tape via RMAN and OSB. Upon restore, RMAN will restore from best media disk or tape based on where files are located.

I want to be able to totally block the FaceTime functionality in my home network. I would like to do this at the router level. Does anyone know the hostname or IP address that the FaceTime application uses? Or which port it connects to?

I want to be able to totally block the FaceTime functionality in my home network so my 4 kids aren't using the Facetime feature- It was easy for Skype just had to enter the work Skype on my Router Security list- and it denies access. I would like to do this at the router level for FaceTime? Only site I find in init.ess.apple.com - is this the startup site for Facetime? Does anyone know a site I can block, hostname or IP address that the FaceTime application uses? Or which port it connects to?

I would presume so, but it might be worth your while to experiment and play around with different combinations to see if you can block FaceTime while keeping Game Center open. Good luck!

ARD won't be as smooth as you think over the Internet and be a security risk for your daughter.
Your best bet would be to install nannyware, then when she's asleep you can review the logs.

Limitations: Mounting File systems

Hi,
We have a requirement to communicate 30 odd application system through XI.
Mostly they are File to SAP or viceversa scenario.
Instead of using FTP Transport protocol, we are planning to use NFS as FTP goes heavy on performance.
Is there any limitation on mounting maximun file systems on XI(on unix) server.
Also suggest the best practice(NFS or FTP) for these kind of scenarios where volume of data and number of interfaces are very high.
Best Regards,
Satish

..."I understand the use of /etc/fstab is now deprecated."...
This is true - but they have been saying that since at least 10.3. Well, "/private/etc/fstab" still working fine in 10.5.1 so I don't imagine there will be a problem continuing to use it for the time being.
In Leopard, it looks like the information is automatically imported into "DirectoryService" under "/mounts" so it might also be possible to configure the mountpoints from there...

Cannot mount file system

Hi,
I have had great advice on this board, and thought maybe someone could help me out. I am following the instructions on installing Enterprise Linux on VMServer. I have just about completed the install, but have ran into the following error message at this step of the instructions:
Format the file system. Before proceeding with formatting and mounting the file system, verify that O2CB is online on both nodes; O2CB heartbeat is currently inactive because the file system is not mounted.

Mount the file system. To mount the file system, execute the command below on both nodes.
# mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs
On rac1, the command to mount the file system works great, no errors. But on rac2, I get the following error:

Does anyone have an idea, I have followed the instructions to the letter, and this is the first error that has me stopped.
Thanks,

Won't mount, file system not recognised

I'm trying to download firmware from Netgear's website but when I try to mount the files they say the file system is not recognised.
I'm trying to get hold of Netgear as well but I thought someone here might have some suggestions too while I wait for a response from Netgear.
The two files I've tried so far are:
http://kbserver.netgear.com/release_notes/D102713.asp
ftp://downloads.netgear.com/files/dg834v2_1022.zip
http://kbserver.netgear.com/release_notes/D103044.asp
ftp://downloads.netgear.com/files/dg8343_0132.zip

My mistake. The file I was trying to mount isn't intended to be mounted. You're actually meant to upload this .img file directly to the modem.

Creation of oracle directory structure on mounted file system in linux

Hi,
I need to use datapump utility for which directory structure would be required. since my dump files are stored another system i usually mount the file system, can i create oracle directory structure on mounted filesystem in linux? do suggest urgently. thanks in advance.

Yes you can why not

Zfs destroy DOES NOT CHECK NFS mount file-systems

I asked this question twitter once and the answer was a good one, but I did some checking today and was surprised!!
# zfs destroy mypool/home/andrew
The above command will destroy this file-system no questioned asked but if the file-system is mounted you will get back the Device busy and if you have snapshot then they will be protected as well
server# zfs destroy mypool/home/andrew
cannot unmount 'tank/home/andrew
server# zfs destroy dpool/staff/margaret
cannot destroy 'dpool/staff/margaret': filesystem has children
use '-r' to destroy the following datasets:
dpool/staff/margaret@Wed18
dpool/staff/margaret@Wed22
BUT?
server# zfs destroy dpool/staff/margaret@Wed18
server# zfs destroy dpool/staff/margaret@Wed22

GONE!!!
I will file a bug report to see what Oracle say!
Comments?
I think there should be a hold/protect of file-systems
# zfs hold dpool/staff/margaret
Andrew

The CR is already filed:
6947584 zfs destroy should be recoverable or prevented
The zfs.1m man page, which covers the mounted case and the ZFS admin guide are pretty clear
about the current zfs destroy behavior.
http://docs.oracle.com/cd/E23824_01/html/821-1448/gamnq.html#gammq
Caution - No confirmation prompt appears with the destroy subcommand. Use it with extreme caution.
zfs destroy [-rRf] filesystem|volume
Destroys the given dataset. By default, the command
unshares any file systems that are currently shared,
unmounts any file systems that are currently mounted,
and refuses to destroy a dataset that has active depen-
dents (children or clones).
I'm sorry that you were surprised.
Accidents happen too, like destroying the wrong file system, so always have good backups.
Thanks, Cindy

AirPort Express vs Extreme. Is this a solution? My wife wants to be able to access files on her hard drive for our Mac by way of a laptop from anywhere in the house. For example, she would like access her $ software from any computer in house.

Will one of these work to use software from iMac on any laptop wirelessly around the house? Which would be better Express or Extreme?

I've had much better luck with Express rather than the Extreme.
She can use "Sharing"

HT3819 Permanently keep files on iPod & other computers via Home Share?

I just got the new iPod Touch iOS6 and I need it to synch with 2 computers (iMac and PC) and my old iPod touch.
I have my a home share set up on my iMac (iTunes 9.2) which has all my purchases over the last 6 years and its synched with my iPod Touch iOS4.
My iMac music library shows up on my Windows iTunes (10.5) via Home Share, but not the movies or TV shows. How do I get all the files (music, movies, tv shows) permanently over to the PC?
What's the easiest way?

ZFS file system mount in solaris 11

Create a ZFS file system for the package repository in the root pool:
# zfs create rpool/export/repoSolaris11
# zfs list
The atime property controls whether the access time for files is updated when the files are read.
Turning this property off avoids producing write traffic when reading files.
# zfs set atime=off rpool/export/repoSolaris11
Create the required pkg repository infrastructure so that you can copy the repository
# pkgrepo create /export/repoSolaris11
# cat sol-11-1111-repo-full.iso-a sol-11-1111-repo-full.iso-b > \
sol-11-1111-repo-full.iso
# mount -F hsfs /export/repoSolaris11/sol-11-1111-repo-full.iso /mnt
# ls /mnt
# df -k /mnt
Using the tar command as shown in the following example can be a faster way to move the
repository from the mounted file system to the repository ZFS file system.
# cd /mnt/repo; tar cf - . | (cd /export/repoSolaris11; tar xfp -)
# cd /export/repoSolaris11
# ls /export/repoSolaris11
pkg5.repository README
publisher sol-11-1111-repo-full.iso
# df -k /export/repoSolaris11
# umount /mnt
# pkgrepo -s /export/repoSolaris11 refresh
=============================================
# zfs create -o mountpoint=/export/repoSolaris11 rpool/repoSolaris11
==============================================I am trying to reconfigure the package repository with above steps. when reached the below step
# zfs create -o mountpoint=/export/repoSolaris11 rpool/repoSolaris11
created the mount point but not mounted giving the error message
cannot mount ,directory not empty When restarted the box, threw service adm screen with error message
not able to mount all pointsPlease advise and Thanks in advance.

Hi.
Don't mix content of directory as mountpoint and what you see after FS was mounted.
On othet ZFS - mount point also clear. You see contetn of ZFS file system.
For check you can unmount any other ZFS and see that mountpoint also clear.

Backup RAC with RMAN..(on diff file system)..URGENT..HELP NEEDED

hello all,
I have not work a lot on SAN storages. One of my client has implementated 9i RAC. Now he wants to Add two more disk in SAN storage (Implemented RAID). So sun engineers will do this but before this i have to take full database backup(80GB database) throught RMAN. The problem or confussion from my side is that the database is on Sun SAN storage and i have to put the Full database backup taken by RMAN on local hard disk on the node (node 1 of rac). Is the possible since the SAN storage is RAW file system (as i guess) and i am putting the backup on local system.
Please help me out ...i have do this in couple of days..
Please tell me prosedure too to how to change the path of backup in RMAN if above is possible..
Its urgent
Thanks and Regards!!
Pankaj Rawat

You best bet is to get your san folks to give you some disk space for a mount point on the last node in the cluster. Once they assign the lun (not raw) have your SAs make it a mounted file system such as /dbbackup.
Run all of your rman backups on your last node on the cluster. The only draw back is, if that node dies, then you will not be able to run backups. but your backups would be safe as they are on the san.
Only way to have a mounted file system on all nodes in your cluser is to have some sort of third party file system cluster ware .. such as veritas or OCFS2 - then all nodes could see it.
I feel the first node in the cluster (the primary node) is the most busy out of the rest .. so thats why the suggestion of running rman on the last node in the cluster.

SC 3.0 file system failover for Oracle 8i/9i

I'm a Oracle DBA for our company. And we have been using shared NFS mounts successfully for the archivelog space on our production 8i 2-node OPS Oracle databases. From each node, both archivelog areas are always available. This is the setup recommended by Oracle for OPS and RAC.
Our SA team is now wanting to change this to a file system failover configuration instead. And I do not find any information from Oracle about it.
The SA request states:
"The current global filesystem configuration on (the OPS production databases) provides poor performance, especially when writing files over 100MB. To prevent an impact to performance on the production servers, we would like to change the configuration ... to use failover filesystems as opposed to the globally available filesystems we are currently using. ... The failover filesystems would be available on only one node at a time, arca on the "A" node and arcb on the "B" node. in the event of a node failure, the remaining node would host both filesystems."
My question is, does anyone have experience with this kind of configuration with 8iOPS or 9iRAC? Are there any issues with the auto-moving of the archivelog space from the failed node over to the remaining node, in particular when the failure occurs during a transaction?
Thanks for your help ...

The problem with your setup of NFS cross mounting a filesystem (which could have been a recommended solution in SC 2.x for instance versus in SC 3.x where you'd want to choose a global filesystem) is the inherent "instability" of using NFS for a portion of your database (whether it's redo or archivelog files).
Before this goes up in flames, let me speak from real world experience.
Having run HA-OPS clusters in the SC 2.x days, we used either private archive log space, or HA archive log space. If you use NFS to cross mount it (either hard, soft or auto), you can run into issues if the machine hosting the NFS share goes out to lunch (either from RPC errors or if the machine goes down unexpectedly due to a panic, etc). At that point, we had only two options : bring the original machine hosting the share back up if possible, or force a reboot of the remaining cluster node to clear the stale NFS mounts so it could resume DB activities. In either case any attempt at failover will fail because you're trying to mount an actual physical filesystem on a stale NFS mount on the surviving node.
We tried to work this out using many different NFS options, we tried to use automount, we tried to use local_mountpoints then automount to the correct home (e.g. /filesystem_local would be the phys, /filesystem would be the NFS mount where the activity occurred) and anytime the node hosting the NFS share went down unexpectedly, you'd have a temporary hang due to the conditions listed above.
If you're implementing SC 3.x, use hasp and global filesystems to accomplish this if you must use a single common archive log area. Isn't it possible to use local/private storage for archive logs or is there a sequence numbering issue if you run private archive logs on both sides - or is sequencing just an issue with redo logs? In either case, if you're using rman, you'd have to back up the redologs and archive log files on both nodes, if memory serves me correctly...

How increase external disk size used for an existing file system, Solaris10

Configuration:
Server: Sun T5220
S/O: Solaris 10 5/08 s10s_u5wos_10 SPARC
Storage: EMC AX4-5
EMC PowerPath: PowerPath Version 5.2
I have the following scenario:
In AX4-5 storage array, I created two LUNs into RAID Group 10, with Raid Type1/0:
LUN 101: 20Gb
LUN 102: 10Gb
Both LUNs were added to Storage Group (SG1) that includes two Servers (Server1 and Server2); both servers have Operating System Solaris 10 5/8 and Power Path.
The servers detect both LUNs across two paths. With Power Path were created a virtual path (emcpower0a, emcpower1a) to access to each LUNs respectively.
We have mounted two file system /home/tes1 over emcpower0a -> LUN101 and /home/tes2 over emcpower1a -> LUN102.
Filesystem size used avail capacity Mounted on
/dev/dsk/emcpower0a 20G 919M 19G 5% /home/test1
/dev/dsk/emcpower1a 10G 9G 1G 90% /home/test2
I want to increase the space in file system /home/test2, without lost the information that I have stored and using the same LUN, LUN 102. To do this I start with the following steps:
1- Create new LUN, LUN 103 with 15Gb into RAID Group 10. Result: OK, I have available space in RAID Group 10.
2- Add LUN 103 to LUN 102, using concatenation option. Result: OK. This action creates a new metaLUN with the same characteristics of LUN 102, but with new space of 25Gb.
After to do these actions, I want to know how Solaris recognize this new space. What I need to do, to increase the size of file system /home/test2 to 25 Gb. Is that possible?
I reviewed the description of each disk using format command, and the disks not have any change.
Could anyone help me? If you need more detail, please do not hesitate to contact me.
Thanks in advance.

Robert, thank a lot for your know how. You helped me to clarify some doubts. To complete your answer, I will add two more details, based on my experience.
After to execute, type -> auto configure and label, the disk was created with different partitions like root, swap, usr, like this:
Volume name = < >
ascii name = <DGC-RAID10-0223 cyl 49150 alt 2 hd 32 sec 12>
pcyl = 49152
ncyl = 49150
acyl = 2
nhead = 32
nsect = 12
Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 682 128.06MB (683/0/0) 262272
1 swap wu 683 - 1365 128.06MB (683/0/0) 262272
2 backup wu 0 - 49149 9.00GB (49150/0/0) 18873600
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 usr wm 1366 - 49149 8.75GB (47784/0/0) 18349056
7 unassigned wm 0 0 (0/0/0) 0
This was not convenient because all information stored appear in the first slice and growfs not work if appear root or swap slice into the disk, for that reason was necesary to recreate manually every slice with partition command. The final result was this:
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 - 49149 9.00GB (49150/0/0) 18873600
1 unassigned wu 0 0 (0/0/0) 0
2 backup wu 0 - 49149 9.00GB (49150/0/0) 18873600
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
Now, execute again the label command to save the new information.
Mount file system and execute:
growfs M file_system mount_point to expand the file system to 9Gb.
