This package contains a set of tools for TRON, the followings are the documentation for each tool.

DB archive provides the ability to reformat the manifest according to the current database, parameters are compatible with the previous ArchiveManifest.

• -b | --batch-size: Specify the batch manifest size, default: 80000.
• -d | --database-directory: Specify the database directory to be processed, default: output-directory/database.
• -m | --manifest-size: Specify the minimum required manifest file size, unit: M, default: 0.
• -h | --help: Provide the help info.

# full command
  java -jar Toolkit.jar db archive [-h] [-b=<maxBatchSize>] [-d=<databaseDirectory>] [-m=<maxManifestSize>]
# examples
   java -jar Toolkit.jar db archive #1. use default settings
   java -jar Toolkit.jar db archive -d /tmp/db/database #2. specify the database directory as /tmp/db/database
   java -jar Toolkit.jar db archive -b 64000 #3. specify the batch size to 64000 when optimizing manifest
   java -jar Toolkit.jar db archive -m 128 #4. specify optimization only when Manifest exceeds 128M

DB convert provides a helper which can convert LevelDB data to RocksDB data, parameters are compatible with previous DBConvert.

• <src>: Input path for leveldb, default: output-directory/database.
• <dest>: Output path for rocksdb, default: output-directory-dst/database.
• -h | --help: Provide the help info.

# full command
  java -jar Toolkit.jar db convert [-h] <src> <dest>
# examples
  java -jar Toolkit.jar db convert  output-directory/database /tmp/database

DB copy provides a helper which can copy LevelDB or RocksDB data quickly on the same file systems by creating hard links.

• <src>: Source path for database. Default: output-directory/database
• <dest>: Output path for database. Default: output-directory-cp/database
• -h | --help: provide the help info

# full command
  java -jar Toolkit.jar db cp [-h] <src> <dest>
# examples
  java -jar Toolkit.jar db cp  output-directory/database /tmp/databse

DB lite provides lite database, parameters are compatible with previous LiteFullNodeTool.

• -o | --operate: [split,merge], default: split.
• -t | --type: Only used with operate=split: [snapshot,history], default: snapshot.
• -fn | --fn-data-path: The database path to be split or merged.
• -ds | --dataset-path: When operation is split,dataset-path is the path that store the snapshot or history, when operation is split, dataset-path is the history data path.
• -h | --help: Provide the help info.

# full command
  java -jar Toolkit.jar db lite [-h] -ds=<datasetPath> -fn=<fnDataPath> [-o=<operate>] [-t=<type>]
# examples
  #split and get a snapshot dataset
  java -jar Toolkit.jar db lite -o split -t snapshot --fn-data-path output-directory/database --dataset-path /tmp
  #split and get a history dataset
  java -jar Toolkit.jar db lite -o split -t history --fn-data-path output-directory/database --dataset-path /tmp
  #merge history dataset and snapshot dataset
  java -jar Toolkit.jar db lite -o merge --fn-data-path /tmp/snapshot --dataset-path /tmp/history

DB move provides a helper to move some dbs to a pre-set new path. For example move block, transactionRetStore or transactionHistoryStore to HDD for reducing storage expenses.

• -c | --config: config file. Default: config.conf.
• -d | --database-directory: database directory path. Default: output-directory.
• -h | --help: provide the help info

Take the example of moving block and trans.

Set path for block and trans.

storage {
 ......
  properties = [
    {
     name = "block",
     path = "/data1/tron",
    },
    {
     name = "trans",
     path = "/data1/tron",
   }
  ]
 ......
}

Execute move command.

# full command
  java -jar Toolkit.jar db mv [-h] [-c=<config>] [-d=<database>]
# examples
  java -jar Toolkit.jar db mv -c main_net_config.conf -d /data/tron/output-directory

DB root provides a helper which can compute merkle root for tiny db.

NOTE: large db may GC overhead limit exceeded.

• <src>: Source path for database. Default: output-directory/database
• --db: db name.
• -h | --help: provide the help info
