Private Node Matcher

zener · June 16, 2019, 5:04pm

After some time I managed to get my private Waves Node and the Waves Explorer working. Everything works fine, except the node’s local matcher. I’ve done everything I think I need to get it working, but I can’t see it running on port 6886, and there is nothing related to the matcher in the node’s log files. See below the output of netstat on the node:

My matcher config:
“matcher”: {
“account”: “3FgzdSRQ9pyfda4v2xk5ax1AmwjFJYMaKWD”,
“bind-address”: “0.0.0.0”,
“enable”: “yes”,
“port”: 6886,
“price-assets”: [
“WAVES”,

“6pmDivReTLikwYqQtJTv6dTcE59knriaodB3AK8T9cF8”
]
},

Setting it to 127.0.0.1 does not enable it either.

Could someone please point me in the right direction here. Since there is no errors in the log file, I don’t know where to even start finding the reason the matcher won’t enable.

Thanks

my config contains additionally:

    # Minimum allowed order fee
    min-order-fee = 300000

    # Fee of order match transaction
    order-match-tx-fee = 10000

    # Matcher's directories
    matcher-directory = ${waves.directory}"/matcher"
    data-directory = ${waves.matcher.matcher-directory}"/data"
    journal-directory = ${waves.matcher.matcher-directory}"/journal"
    snapshots-directory = ${waves.matcher.matcher-directory}"/snapshots"

    # Snapshots creation interval
    snapshots-interval = 1d

    # Invalid/Expired orders cleanup interval
    order-cleanup-interval = 5m

    # Maximum allowed amount of open orders
    max-open-orders = 200

    # Maximum allowed amount of orders retrieved via REST
    rest-order-limit = 100

Feel free to try

Thanks brox,

Sadly no change.

I got the matcher working by downgrading node versions. It looks like every version after 0.17.1 does not start the macther (Maybe it needs a missing config entry or maybe it’s a bug). I now have it listening off port 6886.

The matcher doesn’t ship with the node after some version (maybe it is 0.17.1) and should be installed separately.

scudo.altervista.org · July 6, 2019, 2:03pm

With version 1.0.0 - 1.0.1 in the waves.conf file there is no longer a piece of code:

Matcher settings

matcher {
# Enable / disable matcher
enable = yes

 # Matcher's account address
 account = "YOUR ADDRESS WALLET"

 # Matcher REST API bind address
 bind-address = "YOUR IP DROPLET"

 # Matcher REST API port
 port = 6886

}

How to install matcher separately?

scudo.altervista.org · July 13, 2019, 9:42am

How to reactivate Matcher?

zener · July 13, 2019, 4:18pm

I would also like to know. Can any DEV perhaps share this with us?

brox · July 14, 2019, 6:58pm

Here https://github.com/wavesplatform/dex/releases are the binaries and the docs

sultana · September 18, 2019, 11:53am

Hi brox,

Can you say how to create own matcher?

brox · September 18, 2019, 1:45pm

I didn’t installed it myself, but I am sure it can be done the same way as installing node. Just use different binaries and config file. Have you tried the link above?

sultana · September 19, 2019, 4:47am

yeah but am getting errors. i don’t know how resolve that
