Issue/Introduction

On Domain Manager, the status of OS installation jobs (OSIM jobs) are updated very slowly. It takes time to be activated or changed to pending status

Environment

Client Automation 14.5

Cause

In TRC_CSMACT_*.log logs the qlen for U-CSMACT is high.

Example :

Here qlen is 180

ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiEndPoint::handleMspiMessage : 2aa3ce58 RxMsg from <ip_address>\$U-CSMSERVER SR 4 TR 0 SI 1A5C05FC TI 2CA418B9
ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiEndPoint::handleMspiMessage : Sent to <ip_address>\U-CSMACT
ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiEndPoint::handleMspiMessage : Payload size 1521
ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiEndPoint::handleMspiMessage : AP XX TR 2CA418B9 SR 1A5C05FC DF(0)
ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiMsgHdr::attachToSession : old 00000000 new 29DDD000
ccsmact |CFSMCAPI|CFSMCAPI |000000|DETAIL | SmiEndPoint::enqueueMessage : message 2AA3CE58 qlen 180

 

And in the logs we could see some DNS resolution problem :

ccsmact|cfOSServices|cfOSServices |000000|DETAIL | CCFOSGeneral::GetAddressFromNameEx: pszName: <fqdn_hostname>
ccsmact|cfOSServices|cfOSServices |000000|INFO   | CCFOSGeneral::GetAddressFromNameEx: GetAddrInfoW: 11001 for <fqdn_hostname>
ccsmact|cfOSServices|cfOSServices |000000|INFO   | CCFOSGeneral::GetAddressFromNameEx: GetAddrInfoW (IPv6): 11001 for <fqdn_hostname>

ccsmact|CFUtilities_Help|CFUtilities_Helper |000000|DETAIL | Lookup of <fqdn_hostname> was not found from short name using <hostname>

 

ccsmact plugin tries to resolve a server name to ipaddress using its fqdn or shortname format. But all are failing with error 11001

All these attempts could take about 5 or 6 seconds. During this time ccsmact does not process other incoming requests and the qlen for U-CSMACT is growing.

Resolution

There is a DNS resolution problem for some scalability servers. The solution is to update the DNS server configuration to resolve the DNS resolution problem.
