Hi,

In our ODWek REST api we are getting the following response: No availble connections to pool <poolname>

Request
HTTP request to /cmod-rest/v1/ping
Header includes key / pair

• Authorization = CMODSharedKey <connection_poolname-connection_poolkey>

Response
HTTP Code = 408
Reponse body = No availble connections to pool <poolname>

I have tried to increase the max poolsize in odwek-rest.war even. Any idea what is going on here?
This happends in our test environment - production is fine.

Do the logs in the web server software give any indication as to where the problem might be?  There should be other error messages around the time of your request that might shine some light on the issue.  :)

-JD.

My guess is the pool is not starting correctly. Stop and start the REST application and then look at the arsrestapi.log. It will give you the information you need to verify this.

 Hi, thanks for reply

Our problem was firewall related. ODWek REST not able to connect to CMOD Library Server.
Solved by opening in firewall

Hi Everyone,

I may not original forum owner, but I was founded same issue. (Error 408: No availble connections to pool odpool)
Unfortunely, I have no issue on firewall/connectivity. (WAS/CMODREST/CMODSERVER on same server!)
