This is a simple procedure and basically the same as creating the first instance.

• A separate configuration file is needed. Either copy the default configuration file or copy or the existing eloqdb6.cfg The name of the configuration file is arbitrary.

  Copy the default configuration file:

  $ cd /etc/opt/eloquence6
  $ cp /opt/eloquence6/newconfig/config/eloqdb6.cfg eloqdb6_2.cfg
  

  When copying an existing eloqdb6.cfg file the existing volume entries (in the [Volumes] section at the end) need to be removed.

• Optional: In case the new eloqdb6 instance should run as a different user/group you should create them now. Otherwise use the same user/group as with the previous instance.

• Optional: It is recommended to add a (separate) service name for the new eloqdb6 instance in the /etc/services file and specify a port for it. This allows to use the service name instead of the port number and also documents port number usage.

  eloqdb2 8202/tcp    # Test server
  

  In this example, the service name is eloqdb2 and the port number 8202.

• Edit your new configuration file. The following changes are required/recommended.

  Title = test

  This allows to distinguish the servers in the process listing.

  Service = eloqdb2

  This specifies the service name the eloqdb6 instance should use (a port number, such as 8202 may be used as well )

  ServiceHttp = 8203

  In case the HTTP status is enabled, a different port number must be used for each instance.

  UID = eloqdb
  GID = eloqdb

  Specify the user/group to run this eloqdb6 instance.

  LogFile = /data/log/eloqdb6_2.log

  If a log file is used it is recommended to use a different log file for each eloqdb6 instance.

• Configure autostart for the second eloqdb6 instance. This is defined in config file /etc/rc.config.d/eloquence6

  An entry like below should be added at then end of this file:

  ELOQDB6_CFG[1]=eloqdb6_2.cfg
  ELOQDB6_ID[1]=test
  

  This specifies the configuration file for the second eloqdb6 instance (this assumes it resides in the /etc/opt/eloquence6 directory) and names the instance with the id "test".

• Create the volume files. This is the same procedure as with the first instance. However the configuration file needs to specified on the command line.

  $ dbvolcreate -c /etc/opt/eloquence6/eloqdb6_2.cfg db01.vol
  $ dbvolextend -c /etc/opt/eloquence6/eloqdb6_2.cfg -t log db02.vol
  ...
  

• Start the server.

  /sbin/init.d/eloq6 start test
  

  The id "test" was defined in /etc/rc.config.d/eloquence6 and may be used to specify this instance (also works for stop, etc).

To access the "other" instance the database name needs to specify the service/port number of the instance (eg. :eloqdb2/DB). An easier (recommended) alternative is to set the EQ_DBSERVER environment variable to specify the server.

export EQ_DBSERVER=:8202
