This message generally means that the version of bgscollect installed on the machine is not compatible with the version of the Operating System running on that machine. This generally happens when the Operating System has been upgraded to a new release but the TSCO Agent product has not been reinstalled on the machine.
The 'ERROR: UDR request terminated - collection halted - Operating System mismatch' message means that the version of bgscollect installed on the machine is for a different Operating System than the one the machine is currently running. For several supported platforms such as, for example, Solaris and AIX, the bgscollect binary is specifically built to run on a particular OS version. What sometimes happens is that the TSCO Agent is installed and then the machine gets upgraded to a new OS release. Now the version of bgscollect installed on the machine isn't compatible with the currently running OS. The recommended method to resolve this issue is to reinstall the TSCO Agent package on this machine. The re-install will get the correct version of the bgscollect binary installed on the machine.
The $BEST1_HOME/bgs/log/[hostname]-bgscollect-noInstance.log file on the machine will have more information about the specific Operating System version and bit-width the collector is compatible with and what version of the OS is currently running on the machine.
For example, a Solaris 7 32-bit collector running on a Solaris 9 64-bit machine reports the following errors in the [hostname]-bgscollect-noInstance.log file:
bgscollect (3845) Checking for platform support
bgscollect (3845) Running on SunOS 5.9 (sun4u, 64 bits)
bgscollect (3845) Collector supports SunOS 5.7 (sun4u, 32 bits)
bgscollect (3845) Collector support check failed
bgscollect (3845) The collector does not match the OS Level and/or kernel size.
bgscollect (3845) You may need to upgrade your collector or your OS.
For AIX, the logs show this information:
