System Troubleshooting and Diagnostics
5.2 Product Fault Management and Symptom-Directed Diagnosis
To determine if any resources have been disabled, for example, if cache has
been disabled for the duration of the OpenVMS session, examine the flags for
the SYSTAT register in the packet header.
In Example 5–1, a translation buffer data parity error latched in the TBSTS
register caused a machine check exception error.
