ON-BAR

We are currently using ontape, and are planning to convert to ON-BAR. I am doing to RTFM work right now, but was wondering if there was anything else that any of you could add to make my experience less painful. We were going to use the ISM that comes for AIX, since we are using the single tape drive. We are looking to install another tape drive soon. We are working on our development box, which is very similar to our production machine IBM F50. AIX 4.3.3 IDS 7.31.UC5

Chris, one thing to check first is your BAR_XFER_BUF_SIZE in your onconfig file. I see you're running IDS on AIX which means your page size is 4K as opposed to 2K like other unix platforms (i.e. SCO, Solaris, etc.). The default setting in the onconfig file is 31 which is incorrect for 4K page size operating systems. You have to change it to 15. Another thing is to always make sure you have enough space for your bar_act.log file. Furthermore, while getting this thing up and running, you might wanna get the bar_dbug.log file to start logging for error reporting. Once again you have to make sure there's enough space or your instance will hang. The setting on the BAR_DEBUG_LOG parameter can range from not very verbose to very verbose and can quickly fill up your filesystem! Other than that, I don't use ISM so I can't help you out much there. Best of luck. chris_burton@blue-skies.net wrote: > We are currently using ontape, and are planning to convert to ON-BAR. > I am doing to RTFM work right now, but was wondering if there was > anything else that any of you could add to make my experience less > painful. > > We were going to use the ISM that comes for AIX, since we are using > the single tape drive.
