RE: For IFMX GURU : ONTAPE RESTORE Q

Sanjeev, There is one way that I can think of restoring this backup and that is to use gzip to write to a pipe and then direct into ontape. The reason you can't break the file into 2 gig files is that the end of each file is not in the format that ontape expects. A better way to take the backups would be to do the following: - set the tape size to 2 gig - start the ontape -s -L 0 - when you get the tape change message move the tape file eg: mv ontape.out ontape.partX - touch the tape file (to recreate empty) - hit return to continue the backup - remember to move the last file as well To restore: - rename the first file back to ontape.out - start the ontape -r - when you reach the end of the file, rename the next part to ontape.out Regards David Ashby ______________________________ Reply Separator _________________________________ Subject: For IFMX GURU : ONTAPE RESTORE Q Author: sanjeev sagar [SMTP:sanjeevsagar@rocketmail.com] at WC-KEN Date: 17/7/98 8:57 AM O/S : Sun/Solaris 2.5.1 IDS : IDS 7.30 My database size is 6.5GB. Becuase of some reson i am forced to use "ontape -s -L 0" on DISK. Since my Solaris version deoes not support file size more than 2GB, i used pipe to archive my database as following TAPEDEV pipename [onconfig parameter] I made a small script which in fact use gzip in asynchronous mode and use ontape command like gzip -<pipename>destinationfile.gz ontape -s -L o<<EOF EOF It worked for me. I was able to archive my database in just 399mb[gzip worked great]. Now my problem is to test restore from this zip file. i did following 1. decompress the file into multiple files of 2GB each. So i have total 4 files, last file less than 2GB, total size 6.5GB 2. i set TAPEDEV pipename and on other screen i use dd command or cat command. it gave me error AIRTHMATIC EXPRESSION! Error no 4 My problems are following 1. Since i cannot have file size more than 2GB in unix files sytem[Solaris 2.5.1 does not sipport], i can not concatenate all the files into one file and specify TAPEDEV parameter to that file and start restore. SOMEONE HELP ME THAT HOW CAN I DO RESTORE FROM 4 FILES OF 2GB EACH. Thanks a ton!!!!!!! Sanjeev _________________________________________________________ DO YOU YAHOO!?
