UCMDB in HA shwoing wrong status

Hi,

 

We have  2 UCMDB server 10.10+1 DFP configured in High Availability. Windows 2k8 OS

 

Load balancer configuration had been done as per doc. Steps are mentioned as below.

 

1. create two server pool for physical server  1.1.1.1 and 1.1.1.2

2. created two virtual IPs for both server pool  i.e. 

writer vip  =1.1.1.5

reader VIP=1.1.1.6

 

 

writer vip is monitored by =       /ping/?restrictToWrite=True 

reader vip is monitored by = /ping/

 

 

Now the issue is as below

if writer server=1.1.1.1 & reader server= 1.1.1.2

 

 

1. if   I check the status  of writer and reader component from writer server(1.1.1.1) i get below response which is correct

http://1.1.1.1:8080/ping/?restictToWrite= true   =UP

http://1.1.1.2:8080/ping/?restrictToWrite=true = down

 

2. if i check the status from reader server(1.1.1.2), the response is strange which is showing wrong status.

 

http://1.1.1.1:8080/ping/?restictToWrite= true   =UP

http://1.1.1.2:8080/ping/?restrictToWrite=true = UP

 

 

Please let me know how to resolve this issue??? Unable to figure out where is wrong as same was working fine 3/4 days back.

 

with regards,

Nick

Hi Nick,

 

In the new HA method for 10.x both all systems in the HA cluster are readers and only 1 server in the cluster can be writer. Therefore, the output obtained is correct.

Re: UCMDB in HA shwoing wrong status

Hi,

 

 

Thanks for the reply.But carefully read below details .  I agree that, there is one writer and rest servers are reader .In  present setup, one is writer and other one is reader as below

 

 

But response from "restrict to write" URL is strange from reader server which is UP for reader and writer IP

and as per my understanding it should be UP for writer server IP and DOWN for reader server IP. Whereas response is UP and down which is correct   if  I check the URL from writer server itself.

 

 

SO my query is why "restrict TOWrite"  URL for both server IP is UP  from reader server and DEsktop as well. It should be UP for writer IP and DOWN for reader IP.

 

 

if writer server=1.1.1.1 & reader server= 1.1.1.2

 

 

1. if   I check the status  of writer and reader component from writer server(1.1.1.1) i get below response which is correct

http://1.1.1.1:8080/ping/?restictToWrite= true   =UP

http://1.1.1.2:8080/ping/?restrictToWrite=true = down

 

2. if i check the status from reader server(1.1.1.2), the response is strange which is showing wrong status. and from desktop too

 

http://1.1.1.1:8080/ping/?restictToWrite= true   =UP

http://1.1.1.2:8080/ping/?restrictToWrite=true = UP

 

 

with regards,

Nick

Re: UCMDB in HA shwoing wrong status

Probe could only communcate with writer, that's why  ?restrictToWrite=true was introduced

If your observation is correct, the support case needs to be open.
