Task to install OA package fails with error Cannot fetch FILE_NAME, for example
Task: Install service-logparser-2.86 (pkg_id = 12345) on SERVER_NAME (host_id = 11) Last execution output Destination host 'SERVER_NAME' (#12), IP '10.10.10.10' : Internal error: Cannot fetch 'service-RHES-4-i386-logparser-2.86.tgz': 'file:///root/51.26/os/RHES/4/packages/service-RHES-4-i386-logparser-2.86.tgz: Couldn't open file /root/51.26/os/RHES/4/packages/service-RHES-4-i386-logparser-2.86.tgz ftp://******:*****@184.108.40.206:16384/service-RHES-4-i386-logparser-2.86.tgz: http://220.127.116.11/tarballs/service-RHES-4-i386-logparser-2.86.tgz:'.
In this example 10.10.10.10 is IP address of the serve where package is being installed, and 18.104.22.168 is IP address of OA management node (OA core).
OA package consists of package manifest (XML based configuration file that describes package requirements and other properties) and package body (.tgz archive that contains files that should be copied to managed server during package installation). .tgz files with package bodies are stored on management node and should be accessible via HTTP at address like
Cannot fetch FILE_NAME indicates that the managed server cannot retrieve package body from OA core via http.
Make sure Apache service is running on OA core and file can be retrieved locally from OA core itself:
service httpd status wget http://11.11.1111/tarballs/service-RHES-4-i386-logparser-2.86.tgz
Make sure that from managed server you can open connection to port 80 of the management node:
telnet 22.214.171.124 80 wget http://126.96.36.199/tarballs/service-RHES-4-i386-logparser-2.86.tgz
If there is firewall or network problem preventing connection - it should be fixed by network administrator.
