Again on the Tronscan Map..

And.. we are again back on the map! (14.09.2019 – 9 AM GMT+2)

How come we’ve disapeared?
Sadly.. in Romania, it seems that we are the only server (tron nodes) operators. There were some folks who ran the nodes but now ours are the only one. Once we dropped back to 10.. puf, the country was removed from the map.

Screenshot (before)

10 nodes before 14.09.2019

10 nodes before 14.09.2019 that were run by our SR Candidate

 

 

 

 

 

 

 

 

In order to address the issue I’ve deployed the 11th node. Now, all 11 that are shown on the maps belong to this SR Candidate (TronLabs Romania)

This is how it looks now

[How-to] Convert Block level DB to ROCKS DB

This guide is intended for those who wish to convert from one DB format to another. The benefits are:
– You can use RocksDB as storage engine when you want to back up the database without the node application stopped,
– The Rocksdb engine has more tuning parameters for faster-synchronizing block and takes up less disk space when compared with the Block LevelDB.

Note:
You must only use one db engine (leveldb or rocksdb) throughout the life cycle of node because rocksdb’s data structure is incompatible with the leveldb’s. A convert tool is provided within Java-Tron to convert the leveldb data to rocksdb data and the usage of tool is described below. Please be aware that the conversion take time and the node is not syncing any blocks while this operation is ongoing.

1. First we need to clone the git and build it

git clone https://github.com/tronprotocol/java-tron
cd java-tron/
./gradlew build

Just wait until it’s built and tested. Go grab a cup of tee or a coffee.

2. Then we need to stop the node
3. Now we need to use this Java converter package (DBConvert.jar) to perform the conversion. It is located here: /java-tron/build/libs/

Sample syntax looks like this

java -jar build/libs/DBConvert.jar  your_database_dir/database  output-directory-dst/database

Example syntax looks like this

java -jar /home/userdir/java-tron/build/libs/DBConvert.jar /home/userdir/FullNode/output-directory/database /home/userdir/FullNode/output-directory2/database

According to tron documentation it should take about 10 hours to finish the conversion. Well on my node it took about 67800 seconds. This translates to 18.8 hours. The process is not CPU or Memory bound, both my CPU and Memory usage never exceeded 10% or the allocated resources.

Romania – 10 Nodes online

Hello fellow Tron enthusiasts,

We did it ! As of this morning we have 10 Tron nodes online who are part of the Tron Main Net. This does translate to about 1% of the network. I am very proud to have put “Romania” officially on the Tronscan Nodes ranking map. This shows that we as a community SR, are all in !

Here are the screenshots:

Tronscan Node Ranking shows 11 Nodes online. From this total number, 10 are ours (TronLabs Romania) and one belongs to another tron enthusiast.
