May I use transaction in an stand alone win server with node?

Gustavo_Castro · 2023-09-21T21:05:18.904Z

Hi there, It´s my first time here …
I use one lab to learn and I need to use transactions to insert data in 2 diferent collections, but since yesterday I´m trying and this error message pops in my screen … “Transaction numbers are only allowed on a replica set member or mongos”. I already tryed the node university video and copy the code with my data, and all others internet sources, but i have no success.
I am using an stand alone windows with node (all updated). Is it possible to use transactions in my environment? how ?
ps- I tryed to set up the replication in cfg file, but when I do it the mongo service does not run anymore. ( I also set up the security: authorization enable)

Post the Config File? I got some time to kill if you’d like me to look at it.

@Gustavo_Castro

So it looks like you’re trying to do this for a standalone instance, so do the following:

Stop the service.
Build a new config file like this (add more fields but this is the minimum you have to have):
systemLog:
destination: file
path: “mongod.log”
storage:
dbPath: “M:\data\db”
replication:
replSetName: “replicaSetName”
Start it with the config file.

mongod --config "M:\path\mongod.cfg"

Turn on the replica set

mongo
> rs.initiate()

Check Replica State

> rs.status()

Let me know if this works out for you.

EDIT

@Gustavo_Castro We want to build this with the bare minimum we need, so that way we can narrow down where the configuration is failing.

This is a bit surprising to me. I thought transactions are also available in a standalone node.
Just use a single node replica set for it.

Why replica set is mandatory for transactions in MongoDB? Ops and Admin

Hi Iván, Welcome to the community. You can convert a standalone to a single-node replica set to enable transactions. All you have to do is start mongod with --replset flag. The link posted by Pavel above goes into more detail.

Is it possible to run single replica set with client authentication?
