OTRS cluster not possible/problematic?

[zbigniew]

Hi,

is it possible to do active-active OTRS cluster? (2 otrs work together and share everything)

made a OTRS cluster with 2 nodes:
app1
app2
db1
db2

app1/2 have otrs 4.0.6 app - they are loadbalanced and share common dns name. /opt/otrs/var directory is shared using NFS.
db1/2 is mysql galera cluster

app server have script which checks if db servers are alive every minute and switches them in Config.pm if not plus httpd reload to reload changed Config.pm. Do you know any better option to do this? Can otrs do this without using my script? E.g. can I provide to otrs both db addresses and otrs can use second one if first fails connection?

Because of sharing app servers in otrs logs see error: "Process could not be found in the process table!" because list of linux processes is shared between both app servers it is obvious that processes have different numbers and are found on one server but not other one. Can I hide/turn off this error message?

Hi,

this is hardcore stuff, not possible with standard OTRS and no knowledge of perl, caching, webserverclustering, Unix Mailserver, DNS, Unix Shell, security and so on...
