Files structure change based on the instance

bruceedgar — Wed, 02 May 2007 11:49:05 GMT

Hi Experts ,

I need a favour from you , I have a dump of a instace which contain lots of directories and files , I would like to extract that dump for another instance , The dump will have the strucetue of the old instance Iw ould like to change it to new instance structure .

How to find what are the changes has to be made to get the new instance structure.

Searching and repalcing the strings in a houge file structure is not an easy thing so please suggest me to get optimised.

Thanks & Regards

Bruce.

Hi Bruce,

your request is highly missing specific information:
- what dump you are talking about, what dump program was used, what are your basic data the dump was created from?
- what is the relation of (directory) structure to dump?
- do you want to change the structure or its contents or both?
- what do you search and what is the replacement you want to make? Examples?

MfG Peter

Do a "man dircmp" and see if that suggest anything useful though I doubt it will.

My approach (based upon your limited description of the problem) would be to sort the two files into two new files. The good news is that "/" collates before any alphanumerics so directories should sort together. I would then feed these two files to "sdiff -s" and that should at least be a starting point.

Thanks Peter and Clay,

Actually Iam installatin the software ematrix and rmi for one instance , I would like to take the dump of it after installation and resue it in feature , so taht i can minimize the installation time , but it will differ for each instance , Thats why i wolud like to find the difference in path level and file level , If i find it i can replace them based on the new instance.

Ok, my approach would be to get one system just like I like it and back it up using tar, cpio, pax, fbackup, whatever --- pax might be a good choice if you need to do filename substitution but that really shouldn't be necessary. The key is to not do an absolute path backup but rather a relative path backup. Your copies would then be a restore starting from the top-level directory of your choice.
