AIX

Hi expert,

I am using AIX 64bit version 5.3

I need to configure rsync on it so that we can switch files from one server to other automatically.

Please suggest some doc/way.

Thanks is ADV

Or something like this : Let me google that for you

Any ways, here is the command I use :

Code:

rsync --verbose --relative --recursive --update --delete --perms --owner --group --times --links  --safe-links --super --compress --one-file-system --devices $sourceDir $destDir

Install the following rpm's (These are for AIX 6.1 so if they are not the same for 5.3, then just try to install rsync. It will tell you the dependencies that your missing and just grab them and install them).

gcc
gcc-cplusplus
libgcc
libstdcplusplus
libstdcplusplus-devel
rsync

You can download them from:
IBM AIX Toolbox for Linux Applications - Alphabetical Listing

Then a simple rsync command would be:

Code:

rsync -avz --delete-after /home/* user@system:/home/

There are several other switches to rsync that you can use, so you can check out the help screen by typing

Code:

rsync -h

once you have it installed. But this one should work for a basic rsync. It will also clean up any files on the target system that are not on the source system when it is done syncing. If you dont want that to happen then just leave out the

Code:

--delete-after

If you set up ssh keys between the two systems you can cron it to run at certain times of the day and you will not have to enter a password to make the connection betwen the two systems, rather it will use the keys to authenticate.

To do that just switch user to the user you want to rsync as and:

Code:

ssh-keygen

It will copy your keys in the home directory of the user that you initiate the keygen command as, so something like this /home/user/.ssh/id_rsa.pub.

Take the public key from the source systems and copy it into the destination system under /home/user/.ssh/authorized_keys. If the authorized_keys file does not exist then create it and copy the public key there.

This should get you up and working with rsync. I just put this up off of memory so hopefully i did not miss anything, but this should get you going.

Thanks all for your prompted reply.

There is one thing which confused me.
wether I have already rsync installed or not ?

as oracle user I say:

which rsync
o/p:
/bin/rsync

what is it mean? I have rsync already installed and I can use above suggested commnads or do I need to install some rmp and then proceed further ???


please suggest !

Thanks all again

You can use the "which"-command as any user, not just as oracle. ;-))

"which" is correct and its output means that there is a command named "rsync" located at "/bin/rsync".

A small side remark: note, that "which" just searches through the contents of your PATH-variable. If it doesn't find a specific binary that doesn't mean it isn't there but that it is not found in any of the directories mentioned in the PATH-variable. This is why using "rpm -qa | grep <yourcommand>" is a somewhat more reliable method of finding out if it is installed or not.

I once used rsync in an AIX 5.1 environment and had troubles with it. (The rsync job would tear down the inetd and every other network daemon with it sometimes, resulting in an "autistic" system that could only be revived by a reboot.) Probably my experiences will not apply to the situation today, but a bit caution would be in order. Not that my problem only happened after some bigger amount of data had been transferred and not every time we started "rsync". We never found out what exactly the problem was and ultimately gave up "rsync" altogether.

I hope this helps.
