A script to gather information in the unlikely event that Informix Dynamic Server is hung has been available on UNIX for some time. The tbsupport.ksh script can be downloaded here: What to collect if Informix Dynamic Server gets hung.
Not long ago an equivalent Windows version called tbsupport.bat was published. The Windows version was updated at the end of 2006 to incorporate some additional Windows diagnostic commands such as msinfo32. The new Windows version can be found here: What to collect if Informix Dynamic Server gets hung on the Windows platform. Comments and suggestions for these scripts are always welcome.
