"If you set the environment variable AFDEBUG before you initialize Informix, the engine will suspend processing-rather than crash-during many errors. This is useful because it allows you to run certain diagnostic commands like oncheck and onstat before bringing the engine down. Here is an example of how to do this when initializing Informix:

AFDEBUG=1; export AFDEBUG
oninit

Note:
Because of the improvements for assertion failure handling in 7.3x, setting AFDEBUG is not really necessary; Informix will continue running and capture errors anyway. In the rare cases when an assertion failure crashes Informix, however, AFDEBUG will still work to suspend Informix processing. This allows you to capture error information before bringing down the Informix engine. "
