TREX 7.0 TREXISAPIEXT.dll high availability problem.

EP6.0.11/14

TREX7.0

Trying to configure EP with a Distributed TREX. Got 2 TREX 7.0 servers each with http (application pool). If I have both application pools up, trex monitor in EP will drop indexserver and queueserver and indexing/searching is not possible. However, if only one of the application pool is up TREX monitors shows healthy queueserver and indexserver.

TREX administrator doesn't have any issues though.

Any help would be appreciated.

Hi,

how are the nameservers in your TREX Java client (in EP System configuration) configured? Do you have the backup nameserver configured? (On TREX side too?)

Hi!

On the TREX side, no backup nameserver is configured, but there are 2 nameservers.

As far as in the visual administrator, I plugged in one of the servers as backup nameserver.

Thanks,

Rey

Hi Rey,

it's OK, on the TREX side there could be maximum 3 master nameserver, and you don't have to have slave nameservers. The 1st nameserver will be used until the connection is lost towards it. In that case the 2nd one will be used.

regards,

Miklos
