using onlog with onbar

Hi, Using onlog either reads the contents of the logs from disk if the logs = have not been backed up yet or from tape using the -d option. However = this option only works using ontape. Since I use onbar to save data and logs, I want to know if anyone was = able to read the logs saved by onbar and how exactly. Is there a particular hidden option when we use onlog? Is there a hidden option not documented when using onbar? Thanks in advance for your responses. KB

Hi, onlog -n (#log) | more -n : a specific log I use onbar too and I am able to read the logs either on disk or tape.

This procedure was given to me a while ago by an IBM/Informix support engineer. It makes use of some undocumented switches, but it works. It is particularly useful if you use onbar to backup to files instead of to tape device, in which case the onlog -d tape_dev will not work. Be sure to use export BAR_LOGCHECK=1 if you do not use CSH. Also, be sure to delete files /tmp/onlog* before running the onbar command.
