I am trying to set up Mongo DB as a service under Win XP sp3 (mongod says
sp2), version 2.0.6 pdfile version 4.5

To do this I have set up a config file -
  # mongodb.cfg

  # data directory
  dbpath = "C:\Documents and Settings\xxx\Ubiquiti UniFi\data\db"

  # log file directory
  logpath = "C:\logs\server.log"

  # append to log file
  logappend = true

  # port mongodb listens on
  port = 27117

My command line is -

 "C:\Documents and Settings\Robin StClair\Ubiquiti UniFi\bin\mongod.exe"
--config "C:\Documents and Settings\Robin StClair\Ubiquiti
UniFi\conf\mongodb.cfg" --install

as I wish to set up Mongo DB as a service.

Mongod.exe executes, finds and opens the config file and then an errno:22
is thrown and mongod.exe shuts down gracefully.

I believe this is a Visual C++ error (doesn't like long command strings,
hence my short path to log file (to see if that would get rid of the
problem)).

I would be grateful for some guidance

R+C

I have tried to reproduce your problem but did not encounter the errno 22
error directly but might have replicated your problem and found a solution.

I used similar parameters you listed in configuration file:

dbpath="C:\Documents and Settings\a\xxx\Ubiquiti UniFi\data"
logpath=c:\log\mongo2.log

and I was also not able to successfully install mongod.exe as a service.

When I used this parameter in configuration file:

dbpath=C:\Documents and Settings\a\xxx\Ubiquiti UniFi\data  (Note, without
the quotes)
logpath=c:\log\mongo2.log

I was able to successfully install mongod.exe as a service when I removed
the quotes.

Does this clarify the situation, or affect the error output?

Thanks,
andrew
