LOCKING
=======

This text file archives information about the locking mechanism in the
initial release of the PostgreSQL plugins. THIS INFORMATION IS NOT
VALID ANYMORE!


>>>>>>>>

The plugins implement a locking system to prevent other instances of Orthanc from using the same PostgreSQL database. If for some reason, Orthanc has not properly shutdown (for instance because of a power outage), you will have to manually unlock the database. This can be done by adding the `--unlock` flag at the command line:

{{{
# ./Orthanc Configuration.json --unlock
}}}

If you dislike the locking mechanism and wish to disable it, set the "`Lock`" option to `false` in the configuration:

<code language="json">
{
  "Name" : "MyOrthanc",
  [...]
  "PostgreSQL" : {
    "Lock" : false,
    "EnableIndex" : true,
    "EnableStorage" : true,
    "Host" : "localhost",
    "Port" : 5432,
    "Database" : "orthanc",
    "Username" : "orthanc",
    "Password" : "orthanc"    
  },
  "Plugins" : [
    "/home/user/OrthancPostgreSQL/Build/libOrthancPostgreSQLIndex.so",
    "/home/user/OrthancPostgreSQL/Build/libOrthancPostgreSQLStorage.so"
  ]
}
