timeout error checking

 [1/3] from: jblake::arsenaldigital::com at: 13-Mar-2007 16:07


I have a script that goes thru a list of ips and logs into the postgres db on those ip's to run a query. It runs well when th eip's are all up. I have to admit I didn't add error checking to deal with if the device doesn't respond. Currently, the script exits and doesn't try the rest of the IP's. Do any of yall have a quick way of dealing with something like this? I'm using; utilip: read/lines %/<filenamehere> foreach ip utilip [ result: read join pgsql: <query here> if find result "false"[ write %<errorfilehere> Do I need to another "if find result" but have the timeout response in there? ..reading the Rebol book and "Rebol for Dummies" for info.................. Thanks John

compleatly untested in anyway (including spell checking) but should give hints for new words to look up utilip: read/lines %/<filenamehere> foreach ip utilip [ if error? err: try [read join pgsql: <query here>][ write %<errorfilehere> probe disarm err ] ] -- ... nice weather eh

Thanks I went with this; foreach ip utilip [ if error? err: try < initial test queryinfo> ] [ err: disarm err either err/id = 'no-connect' [ ] [ result: read join pgsql:<actual queryinfo> The results of the query will either be "true" or "false". Granted, it could connect to the dbase twice if everythings ok. I couldn't figure out how to use 1 query and then test to see if it timed out or test the results. Thanks for the help John
