Component : Adaptive Computing Controller 7.xx - Host Agent

Summary :
Unable to load the ITSAM ComputerSystem may result from non-functioning SAPHostagent processes: sapstartsrv or SAPOscol. For resolution, ensure sapstartsrv is active using the command /saphostctrl -function GetComputerSystem. If the error “Unable to load ITSAMComputerSystem” appears, confirm SAPOscol's functionality. Errors such as NIECONN_REFUSED suggest a non-running sapstartsrv; restarting the SAP Hostagent is advised. Additionally, verify SAPOscol execution and address potential issues from upgrades or mounts, referring to SAP notes 0001113545 and 1415488 for further guidance. Restart procedures and checks for shared memory and mounts are also recommended to rectify persistent issues.
