The repository contains two plugins to store the data in MongoDB database.
This chapter describes the process of installation with not too much details and not necessarily contain all how-to to resolve possible problems that might appear.
- Install boost (compile or with package manager)
- Install jsoncpp
- Install/build mongoc library http://mongoc.org/libmongoc/current/installing.html
- Install/build mongo-cxx lib https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/
- Download Ortanc sources or install orthanc-devel package

ORTHANC_ROOT
- the Orthanc server sources root to include theorthanc/OrthancCPlugin.h
BUILD_TESTS
- option to build tests, default offBUILD_WITH_GCOV
- option to include coverage default off
Add plugins in the Ortahc json configuration file:
...
"Plugins" : [
"libOrthancMongoDBIndex.dylib",
"libOrthancMongoDBStorage.dylib"
],
// MongoDB plugin confihuration section:
"MongoDB" : {
"EnableIndex" : true, // false to use default SQLite
"EnableStorage" : true, // false to use default SQLite
"ConnectionUri" : "mongodb://localhost:27017/orthanc_db",
"ChunkSize" : 261120
},
...
Also it's possible to configure the plugin with separate config options:
"Plugins" : [
"libOrthancMongoDBIndex.dylib",
"libOrthancMongoDBStorage.dylib"
],
"MongoDB" : {
"host" : "customhost",
"port" : 27001,
"user" : "user",
"database" : "database",
"password" : "password",
"authenticationDatabase" : "admin",
"ChunkSize" : 261120
}
NOTE: Setting up the ConnectionUri overrides the host, port, database params. So if the ConnectionUri is set, the other parameters except the ChunkSize will be ignored.
Testing is described with more details in here
- ConnectionUri must contain the database name due to the bug in the mongocxx driver CXX-1187
- The Orthanc server should be compiled in Release or RelWithDebInfo mode to turn off assertions. There are asserts like that `./OrthancServer/ServerIndex.cpp: assert(index_.currentStorageSize_ == index_.db_.GetTotalCompressedSize());``` it involves full collection scan to aggregate the total AttachedFiles significantly slows the performance down.
