Configuration

To run replication in a Docker container or directly via TimeBase Shell CLI, refer to the following instructions:

Replication Between Two TimeBase Instances​

This instruction describes how to live replicate data from one TimeBase instance to another via TimeBase Shell in Docker.

For this example we will use three components which are started one by one in the following order:

  1. TimeBase Master - source instance
  2. TimeBase Slave - target instance
  3. Replication - data replication script

Docker Compose​

Run Docker Compose with the configurations for each of the components. Mounted volumes of each component override common configurations in case other than common values are supplied.

TimeBase Master Configurations​

Custom admin.properties parameters:

# TimeBase Master host name
TimeBase.host=timebase-master

TimeBase Slave Configurations​

Custom admin.properties parameters:

# TimeBase Slave host name
TimeBase.host=timebase-slave

Replication Configurations​

  1. Create and mount start-replication.sh script to start using TimeBase Shell. See Guide for your reference.

    # Example
    #!/bin/sh
    /timebase-server/bin/tickdb.sh -exec exec /replication/replication.script

  2. Create and mount replication.script script to run live replication via TimeBase Shell. See Guide for your reference. See docker-compose.yaml example earlier in this section. 

    # Example
    set db dxtick://username:password@timebase-slave:8011 # Username and password from UAC settings
    open
    set srcdb dxtick://username:password@timebase-master:8011 # Username and password from UAC settings
    set cpmode live
    set reload prohibit
    set srcstream <stream_name>
    replicate <stream_name>
info

Refer to Replication for more information about TimeBase replication options.

User Access Control​

In admin.properties configuration file specify the following parameters to enable UAC: 

QuantServer.security.rulesConfig=uac-access-rules.xml //users authorization information
QuantServer.security.userDirectoryConfig=uac-file-security.xml //users authentication information
QuantServer.security=FILE
info

Refer to UAC Rules for more information.
