Hello everybody,
I am going to setup a failover solution, that is 2 db
server (InnoDB as storage engine)with the second
starting when the first crashes, using Red Hat Cluster
Suite and a SAN to store the data files.
I would like to know if I must enable external-locking
option on my.cnf file. I am doubtful about it, maybe
it is not necessary, Red Hat Cluster Suite should
handle everything and InnoDB locks anyway the data
files, right?
Thanks for any help.
Stefano
OK, it works properly, at least it seems so!
For this forum's friends, a brief summary.
Do not use external-locking, only a server writes.
Binlog file is in the shared storage, too.
In case of crash of the active node, there is a switch to the stand-by node. The autorecovery starts, rollbacks the uncommitted transactions and InnoDB is started too.
