FYI: testing with 8 instances (was Re: [opencms-dev] Question about administrator rights)

[Sven Dittmar]

Hi there,

we had short testsession today with 8 different instances of opencms 
(oc-beta52, mysql 3.23,  jakarta-tomcat-4.1.12 and j2sdk1.4.1_01)

The result is was eerm interesting. :-)

Half of the people had crashes like

Unknown exception. Detailed Error: CmsException ID: 0. Caught Exception: 
 >java.lang.IllegalArgumentException: Packet is larger than 
max_allowed_packet from server configuration of 1047552 bytes<

and many locking errors.

The performance was getting quiet slow. You sometimes had to wait more 
than 5 seconds for a change in the browserwindow.

The system worked smoothly and quick in one instance before that test.

Result is: It's not a good idea to circumvent the oc-usermanagement with 
multiple oc-instances.

Did no one try something similiar before?

Regards,
Sven
