After fixing PXC-3918, explicit addition of socket.ssl option is not needed.


To avoid entering the options each time you start ``garbd``, edit the options in the configuration file. To configure *Galera Arbitrator* on *Ubuntu/Debian*, edit the :file:`/etc/default/garb` file. On RedHat or derivative distributions, the configuration can be found in :file:`/etc/sysconfig/garb` file.

* Node 1: ``update i = i + 10;``
* Node 2: ``update i = i + 100;``

Let's associate transaction ID (``trx-id``) for an update transaction
Let's associate transaction ID (``trx_id``) for an update transaction
that is executed on Node 1 and Node 2 in parallel.
Although the real algorithm is more involved (with ``uuid`` + ``seqno``),
it is conceptually the same, so we are using ``trx_id``.

* Node 1: ``update action: trx-id=n1x``
* Node 2: ``update action: trx-id=n2x``
* Node 1: ``update action: trx_id=n1x``
* Node 2: ``update action: trx_id=n2x``

Both node packets are added to the channel,
but the transactions are conflicting.
