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?
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
