Commands for generating tracing information

XBM includes tracing features to help with problem diagnosis and resolution.

BMC Customer Support might ask you to run these traces if you encounter an issue and need assistance.

These commands include:

  • PRINT DTRACE

  • PRINT ETRACE

  • SET PRINTTRACE

  • SET SHUTDOWNTRACE

  • SET ABENDTRACE

Warning

These commands can cause excessive output that can impact system performance. Use these commands only when directed by BMC Support to diagnose a problem.

The basic syntax for these options is as follows.

ssid commandName keyword
