After the deployment in WebLogic server, we started observing the exceptions in server logs with the error message  "JBO-28102 - A Request was timed out while waiting for a Resource". This exception normally happens when there is no available resource to allocate new database connection.  To avoid such exceptions, there are options such as tuning connection pool configurations besides that, Below two other solutions that we have tried to resolve this issue, I believe any one of these will be useful for your us...
