problme to connect to database maximum capacity of pool
In the AdminServer.log we found problem. ####<Jul 23, 2019 7:36:30,853 AM IDT> <Info> <Common> <hot-wizapi-prod-01> <AdminServer> <[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <e735bb14-df4c-44b2-9678-7218ca67d1cb-00000b0e> <1563856590853> <[severity-value: 64] [rid: 0] [partition-id: 0] [partition-name: DOMAIN] > <BEA-000627> <Reached maximum capacity of pool "WizardPool", making "0" new resource instances instead of "1".>
what does its means?
We also got problem to connect to database from WL application and after 2 minutes the connection was ok, any idea why?
it happened several times during day in our production server, also how can I monitor history events like the above problem to connect to the database? and how to verify that our WL configuration is fit with the operation?
