Trouble starting Primary confserv after Failover

[phil]

hi,

i think i messed up my cfg- files again. both 'confserv' and 'confserv_HA'  start up properly. but when the confserv_HA becomes primary due to a failover confserv can't initialize again, afterwards. If I switch off confserv_HA primary, then  confserv is able to initialize again. I'm not sure about the naming convention in the Cfg- file concerning Backup Config Server. Following Message is put out in Log:

Std 04502 Cannot connect to ConfigurationServer '' at host 'test1.domain.de', port 2020, reason 'CFGServerNotFound' on dbsync_violated executed when server is not fully loaded

provide log files from you promary conf. server immediately after it restart.

Hi Phil,

Message in your log is clear - there is another Configuration Server in primary mode running using the same database thus Configuration Server cannot initialize properly.

It seems to me that your primary Configuration Server is unable to connect to backup CS (by meaning of deployment) so it tries to start in primary mode. Please check that you have configured correctly backup server in CME (application "confserv", tab "Server Info") and there is no firewall blocking communication between primary and backup Configuration Servers.

R.

[phil]

hi rené,

thanks for your feedback.

the backup for the primary is properly configured. the proper failover is confirming this. afaik, the primary has not to be configured as backup for the backup CS.
Firewall is a good hint. Indeed, both hosts are configured in the same subnet, but a telnet shows the port 2020 is blocked. im gonna figure that out. must be kinda local firewall.

Cheers

Phil

[phil]

everything#s fine now...

i couldnt find any firewall. after restarting confserv_HA while confserv was running the port could be reached. im not really sure what this is supposed to mean, but at least it's working 100 % proper

thanks for your effort, folks

cheers
