is service available on host of OBIEE cluster?

Question

Hi all

We have 2 node OBIEE cluster. And we have roundrobin balancer

One day we notice that:

1. all services on node's up and running. I get status.sh and see all service RUNNING

2. I get report from user's that they cannot login into OBIEE

3. I have direct link to every node by http..so i go directly to Node1 & Node2  and notice - I can NOT get logon page to one node. NO HTTP connect!

4. I restart problem node  and now it's OK

Balancer fellow's ask me:

"Can you give us url which balancer can use for solution: is service up or not?"

Indeed.. which url i can use for monitor by HTTP OBIEE ? Is url can give me information about service healthy?

Seems to be I cannot use any url which return any static content.

Have you looked through the script? As of line 326 the check_analytics() does precisely that:

For HTTPS it's a couple of lines below and it depends on which port it is running on.

Hi Christian!

It's very usefull link, thanks!

But we have to monitor  time to time (about 1 minute .. for example ) OBIEE nodes from balancer-node by http(s)

And we solved this problem for a while:

- Balancer node ask Node1 about http://my_node1:1111/analytics/saw.dll?BIEEHome&startPage=1

If get 200 - node is alive

If not - balancer make decision DON'T direct HTTP(s) flow to Node1 and move to healthy node (Node2?)

- Balancer node ask Node2 about http://my_node2:1111/analytics/saw.dll?BIEEHome&startPage=1

If get 200 - node is alive

If not - balancer make decision DON'T direct HTTP(s) flow to node Node2 and move to healthy node (Node1?)

Our balancer is good enough to make decision

I think  there is some more special  url for diagnose problem on each node.
