Issue/Introduction

XCOM trace files on the Tandem are created as Format 1 files. A Format 1 file cannot exceed the 2GB minus 1MB size, whereas a Format 2

 

can exceed the 2GB minus 1MB size limit. How do we create a Format 2 trace file?

Environment

XCOM r11.0 for Non-Stop(Tandem)

Resolution

Here are several ways to address the problem:

 

1. Purge all current XCOM logs and traces

2. Set the following XCOMCNF parameters:

 

       RTRACEFILE=$vol.subvol.XCOMTRC

       TRACE=9

       XLOG_FILE_TYPE=ENTRYSEQ

 

   Create a Format 2 Entrysequence trace file.

 

   Example on how to do that:

 

     FUP /IN MKXCTRC/

 

      MKXCTRC:

      set type e

      set code 0

      set format 2

      set ext (50,20)

      set rec 256

      set block 4096

      show

 

      create xcomtrc
