Hi, I got this error using mysqlhotcopy: DBD::mysql::db do failed: Can't find file: './Tecnowind/tqgrppia.frm' (errno: 24) at /usr/local/mysql/bin/mysqlhotcopy line 375. Issuing rollback() for database handle being DESTROY'd without explicit disconnect(). and perror 24 says: Error code 24: Too many open files Ok, the point is that the database has 865 tables: # ls -al /home3/Oasi/files/Tecnowind/*.MYI | wc -l 865 The mysqlhotcopy script at line 375 try to lock all tables at once. $dbh->do("LOCK TABLES $hc_locks"); I got this error with 3.23.34a and 3.23.36 mysql versions. Could someone give me a solution ? I think that some parameter should be tuned (open tables limit ???) Thanks in advance PS: Yesterday, I have completed an installation with 120 concurrent users, with OASI, our ERP based on mysql (OF COURSE) and it runs very very well ! The hardware is a bi-processor XEON 733 MHZ with 2GB of RAM and 60 gb HD (SCSI). There are 4 databases that shares some common tables ! marcello --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
