Caching LAM

In our HA architecture, Caching LAM 1 and 2 run in an active / passive HA pair. The LAM components are installed on servers 6 ,7, 9 and 10:

  • Core 1: Server 6

  • Core 2: Server 7

  • Caching LAM 1: Server 6

  • Caching LAM 2: Server 7

  • Local RabbitMQ Node 1 on LAM 1: Server 9

  • Local RabbitMQ Node 2 on LAM 2: Server 10

Install Caching LAM 1 and LAM 2

  1. Make a copy of the corresponding Config LAM file and rename it accordingly. The default config file is $MOOGSOFT_HOME/config/mooms_cache_lam.conf.

  2. Edit the config file to populate the brokers and virtual_host properties:

    brokers:
[
    { host : "<server 9 hostname>", port : 5672 },
    { host : "<server 10 hostname>", port : 5672 }
    }
],
virtual_host : "<local RabbitMQ ZONE name>",

  3. Configure the ha section of the same file according to the type of LAM and its corresponding HA setup.

  4. Create the service script pointing to the file.
