please provide the command used to backup the source. You will need to correct the backup script and take another backup which includes all files.
did you have insufficient space when unzip ?
Most likely the database was up when the tar ball was created.
Run checksum on both source and target to confirm.
Always keep log of tar and untar. It will help
I do not know how to run check sum
Kindly give sample docs.
I do cold backup the apps and dbtier when instance is shutdown, using
tar -zcf app.tar.gz /u01/applmgr
tar -zcf db.tar.gz /u01/oracle
There is large space when I unzip it at target server. I unzip it using:
tar -zxf app.tar.gz
tar -zxf db.tar.gz
I also unzip it from source and the files are complete, but unzip at target have missing files.
I downloaded md5sum.exe . Is it for linux or windows?
The sample doc show sample command as > md5sum app.tar.gz
But linux will not run it without the .exe I understand .sh is for linux?
Install pigz for parallel gzip and backup like below:
rpm -Uhv pigz-2.2.5-1.el6.x86_64.rpm
tar -cvPf - /u01/oracle | pigz > /backup/db.tar.gz
tar -cvPf - /u01/applmgr | pigz > /backup/app.tar.gz
I can backup Vision 12.2.0 in 12 minutes with this method.
md5sum comes with linux OS. Just run md5sum db.tar.gz and md5sum app.tar.gz on source and target.
Thanks Michael and all
Does md5sum will have the same output in OL vs RHEL linux? as well as in Windows?
Because I can also winscp the db.tar.gz in to my windows laptop, then run md5sum.exe.
