Readtrace Error aborts import of .trc files

Jul 23, 2011 at 12:12 AM


I ran a replay of a trace captured from production using ostress on a QA box while simultaneously running Perfstats 2008 script SD_Detailed. When I try to import the .trc files using SQLNexus, the process fails at 11th file with error:


A serious error condition (1 == cColHeader.fNullable) has been encountered.
    Input Error: Column bitmap indicates NULL but column metadata indicates the column is not NULLABLE.
    File: .\rpcbinary.cpp
    Line: 992
    Return Address: 0x000000013FB939F5
    Function: CBinaryRPC::Initialize
For input errors validate the input with another qualified utility such as Profiler, Explorer, ...


The trace file opens up fine in profiler. Please advice.

What version of RML Utilities are you using? The latest public version of RML Utilities is available @ If you are not on this version, please try importing the trace file using this version. If it fails, then could you send the ReadTrace.log to
