Got the error while testing the first datasource connection in DM mode :
"XQE-CON-0007 XQE error encountered:
DPR-ERR-2002 Unable to execute the request because there were no connections to the process available within the configured time limit"
Cogserver.log shows that Query Service first faulted during start up :
"ueryService failed to start with the following command-line arguments: [/opt/ibm/JAVA7.0/jre/bin/java, -Xms1024m, -Xmx1024m, -Xmnx512m, -Xmns512m, -server, -Xscmx100m, -Xshareclasses:cachedir=../data,name=cognos10%u,nonfatal, -Xmso512K, -Xcompressedrefs, "
But in Cognos Connection Query service shows started.
Linux machine not able to resolve the machine name due to incorrect IP in the hosts file.
Resolving the problem
