Validators

Ripple Labs is now running five validators. You can use this template for your validators.txt file (or place this in your config file):

[validators]
n9KPnVLn7ewVzHvn218DcEYsnWLzKerTDwhpofhk4Ym1RUq4TeGw    RIP1
n9LFzWuhKNvXStHAuemfRKFVECLApowncMAM5chSCL9R5ECHGN4V    RIP2

n9KF6RpvktjNs2MDBkmxpJbup4BKrKeMKDXPhaXkq7cKTwLmWkFr    RIP5

You should also raise your quorum to at least three by putting the following in your rippled.cfg file:

[validation_quorum]
3

If you are a validator, you should set your quorum to at least four.

IPs

A list of Ripple Labs server IP addresses can be found by resolving r.ripple.com. You can also add this to your rippled.cfg file to ensure you always have several peer connections to Ripple Labs servers:

[ips]
54.225.112.220 51235
54.225.123.13  51235
54.227.239.106 51235
107.21.251.218 51235
184.73.226.101 51235
23.23.201.55   51235

New RocksDB back end

RocksDB is based on LevelDB with improvements from Facebook and the community. Preliminary tests show that it stall less often than HyperLevelDB.

If you are switching over from an existing back end, you have two choices. You can remove your old database or you can import it.

To remove your old database, make sure the server is shutdown. Remove the db/ledger.db and db/transaction.db files. Remove all the files in your back end store directory, db/hashnode by default. Then you can change your configuration file to use the RocksDB back end and restart.

To import your old database, start by shutting the server down. Then modify the configuration file by renaming your [node_db] portion to [import_db]. Create a new [node_db] section specify a RocksDB back end and a different directory. Start the server with rippled --import. When the import finishes, stop the server (it can take several minutes to shut down after an import), remove the old database, put the new database into place, remove the [import_db] section, change the [node_db] section to refer to the final location, and restart the server.

The recommended RocksDB configuration is:

[node_db]
type=RocksDB
path=db/hashnode
open_files=1200
filter_bits=12
cache_mb=256
file_size_mb=8
file_size_mult=2

Configuring your Node DB

You need to configure the NodeBackEnd that you want the server to use. See above for an example RocksDB configuration.

  • Note: HyperLevelDB and RocksDB are not available on Windows platform.

rippled Version 0.12

rippled version 0.12 has now been released. This release is currently the tip of the master branch and can be found on GitHub. The tag is v0.12.0.

Prior to building, please confirm you have the correct source tree with the git log command. The first log entry should be the change setting the version:

commit d0a9da6f16f4083993e4b6c5728777ffebf80f3a
Author: JoelKatz <[email protected]>
Date:   Mon Aug 26 12:08:05 2013 -0700

    Set version to v0.12.0

Major Partner Issues Fixed

  • Server Showing "Offline"

This issue was caused by LevelDB periodically compacting its internal data structure. While compacting, rippled's processing would stall causing the node to lose sync with the rest of the network. This issue was solved by switching from LevelDB to HyperLevelDB. rippled operators will need to change their ripple.cfg file. See below for configuration details.

  • Premature Validation of Transactions

On rare occasions, a transaction would show as locally validated before the full network consensus was confirmed. This issue was resolved by changing the way transactions are saved.

  • Missing Ledgers

Occasionally, some rippled servers would fail to fetch all ledgers. This left gaps in the local history and caused some API calls to report incomplete results. The ledger fetch code was rewritten to both prevent this and to repair any existing gaps.

Significant Changes

  • The way transactions are saved has been changed. This fixes a number of ways transactions can incorrectly be reported as fully-validated.
  • doTransactionEntry now works against open ledgers.
  • doLedgerEntry now supports a binary option.
  • A bug in getBookPage that caused it to skip offers is fixed.
  • getNodeFat now returns deeper chains, reducing ledger acquire latency.
  • Catching up if the (published ledger stream falls behind the network) is now more aggressive.
  • I/O stalls are drastically reduced by using the HyperLevelDB node back end.
  • Persistent ledger gaps should no longer occur.
  • Clusters now exchange load information.

Update April 2014 - Due to a vulnerability in OpenSSL the validator keys above have been cycled out, the five validators by RippleLabs use the following keys now:

You should also raise your quorum to at least three by putting the following in your rippled.cfg file:

[validation_quorum]
3

If you are a validator, you should set your quorum to at least four.

IPs

A list of Ripple Labs server IP addresses can be found by resolving r.ripple.com. You can also add this to your rippled.cfg file to ensure you always have several peer connections to Ripple Labs servers:

[ips]
54.225.112.220 51235

Node DB

You need to configure the NodeBackEnd that you want the server to use. In most cases, that will mean adding this to your configuration file:

[node_db]
type=HyperLevelDB
path=db/hashnode
  • NOTE HyperLevelDB is not available on Windows platforms.

Release Candidates

RC1 was the first release candidate.

RC2 fixed a bug that could cause ledger acquires to stall.

RC3 fixed compilation under OSX.

RC4 includes performance improvements in countAccountTx and numerous small fixes to ledger acquisition.

RC5 changed the peer low water mark from 4 to 10 to acquire more server connections.

RC6 fixed some possible load issues with the network state timer and cluster reporting timers.

Issues

Fetching of historical ledgers is slower in this build than in previous builds. This is being investigated.
