In a separate window run the mongo.exe file to open mongo shell: "c:\Program Files\MongoDB\Server\3.4\bin\mongo.exe" Setting up MongoDB as a windows service "c:\Program Files\MongoDB\Server\3.4\bin\mongod.exe" -config "c:\mongo\mongod.cfg" The -config option need to specify the path to the mongod.cfg file. To start MongoDB we need to run the mongod.exe which is in the bin directory of the mongodb installation folder. systemLog:Īt this point we are ready to start MongoDB server on windows using the windows CMD. txt file extension) and add following configurations to the configuration file. Create a new file called 'mongod.cfg' at 'c:\mongo\' ( Look for the file extension, by default windows hide the. We need to create the Configuration file for the MongoDB Server. Mkdir c:\mongo\logs Create mongod.cfg configuration file MongoDB installer does not create these data directories, so we need to create them manually. We need to create the Data folder for the NoSQL database server as well as Logs folder. If you go with the default installation options, mongodb will be installed to the "C:\Program Files\MongoDB" folder.

However some of the lock modes could not exist simultaneously with other lock modes on a resource.įollowing table illustrates the combination of lock modes which are allowed and which are not.Once the download is finished, run.

When a read operation is triggered for a Document, the control must do the following series of locks : Whenever there is a read operation, Shared (S) lock mode must be applied on the resource.Īs Document is the resource in this scenario, Shared (S) lock mode must be applied on the Document.įor all outer levels : Database, Global, Collection Intent Shared (IS) must be applied. The Collection must be locked in Exclusive (X) lock mode, to apply write operation on the Collection.Įxample 2 – Locking a Document for Readingĭocument is granular level (or the resource) for this example.The Database must be locked in Intent Exclusive (IX) lock mode, with an intent to apply write operation in a granular level (Collection / Document).The MongoD instance must be locked in Intent Exclusive (IX) lock mode, with an intent to apply write operation in a granular level (Database / Collection / Document).When a write operation is triggered for a Collection, the control must do the following series of locks : Whenever there is a write operation, Exclusive (X) lock mode must be applied on the resource.Īs Collection is the resource in this scenario, Exclusive (X) lock mode must be applied on the Collection.įor all outer levels : Database, Global Intent Exclusive (IX) must be applied. For example, if IX is applied to a database, then it means that lock holder is willing to apply a Exclusive ( X) lock on Collection or Document level.Įxample 1 – Locking a Collection for WritingĬollection is granular level (or the resource) for this example. IX – Intent Exclusive – This lock mode indicates that the lock holder will modify the resource at a granular level.For example, if IS is applied to a database, then it means that lock holder is willing to apply a Shared ( S) lock on Collection or Document level. IS – Intent Shared – This lock mode indicates that the lock holder will read the resource at a granular level.Exclusive mode is used for write operations.

S – Shared – This lock mode allows concurrent readers to share the resource.
