TP system log can't be opened

Hi,

I can't open the tp sysetm log file in production server. It displayed the error "
SID\sapmnt\trans\log\slog0829.prd could not open.

The same error occured in Development box also.

File slog0829.prd is not found in that directory.

how to solve it and how to see the tp log.

Regards

Somu
