Hello
I created a perl script that might help. Because I like to have a full backup
of my databases and table backups (I know I can split the full backup, but
I'm too lazy ;), I created a perl script that queries MySQL for the table
names in the database and then creates a shell script with individual
mysqldump commands for each table, after it creates the script it executes
it. I think this will help in this case because it is only asking MySQL to
dump one table at a time. With 10,000 tables the script will run for a long
time, but at least it will be automated. Contact me off the list and I will
be glad to send it to you.
Have a great day...
John
Someone please correct me if my idea of how mysqldump runs (i.e. it will
still attempt to open all files) is incorrect.
