| 20 : | =head1 NMPDR Emergency Switch | ||
| 21 : | |||
| 22 : | This method will rename files in the HTML root of the NMPDR website in order | ||
| 23 : | to bring the NMPDR up or down. While it is down, the main page will redirect | ||
| 24 : | users to the backup copy of NMPDR (the "mirror site"). The single | ||
| 25 : | command-line parameter should be C<off> to turn the NMPDR off (redirecting | ||
| 26 : | users to the backup web site) or C<on> to turn it back on. | ||
| 27 : | |||
| 28 : | The currently-supported command-line options are as follows. | ||
| 29 : | |||
| 30 : | =over 4 | ||
| 31 : | |||
| 32 : | =item user | ||
| 33 : | |||
| 34 : | Name suffix to be used for log files. If omitted, the PID is used. | ||
| 35 : | |||
| 36 : | =item trace | ||
| 37 : | |||
| 38 : | Numeric trace level. A higher trace level causes more messages to appear. The | ||
| 39 : | default trace level is 2. Tracing will be directly to the standard output | ||
| 40 : | as well as to a C<trace>I<User>C<.log> file in the FIG temporary directory, | ||
| 41 : | where I<User> is the value of the B<user> option above. | ||
| 42 : | |||
| 43 : | =item sql | ||
| 44 : | |||
| 45 : | If specified, turns on tracing of SQL activity. | ||
| 46 : | |||
| 47 : | =item background | ||
| 48 : | |||
| 49 : | Save the standard and error output to files. The files will be created | ||
| 50 : | in the FIG temporary directory and will be named C<err>I<User>C<.log> and | ||
| 51 : | C<out>I<User>C<.log>, respectively, where I<User> is the value of the | ||
| 52 : | B<user> option above. | ||
| 53 : | |||
| 54 : | =item h | ||
| 55 : | |||
| 56 : | Display this command's parameters and options. | ||
| 57 : | |||
| 58 : | =item phone | ||
| 59 : | |||
| 60 : | Phone number to message when the script is complete. | ||
