System requirements

The recommended deployment consists of:

  • A host machine that will run the docker containers
  • PostgreSQL database running in an separate host

PostgreSQL

  • PostgreSQL 14
  • PostgreSQL 15

We always recommend using the latest available minor release.

It is recommended to dedicate the PostgreSQL environment to the Identity Analytics solution.

PostgreSQL RAM

A minimum of 8Gb is required. It is recommended to allocate between 16Gb and 32Gb (dynamic allocation is possible on a virtual machine) as the number of identities, accounts, permissions loaded have an impact on the final storage space of the database as well as the number of simultaneous connections expected. As a reminder, each client process has its own private memory area (work_mem).

PostgreSQL Hard Drive

Your choice of hard drive will determine the performance of your database. Prefer fast disks such as SAS 15K RPM, or SSD disks for example (with backup battery) for storing the WAL and statistics. This part is crucial so please consult your storage experts for a better expertise.

PostgreSQL CPU

The number of cores will help with parallel processing and determine the number of parallel client connections possible. The frequency is less important than the number of cores.

This is a configuration example that can be used in most cases for Linux:

  • Processor: Intel(R) Xeon(R) CPU E5-2660 v4 @ 2.00GHz (Number of cores / Threads: 14 / 28)
  • Memory: 16 Gb
  • Network Ethernet: 1Gb
  • Hard Drive: SAS 15K RPM + SSD

Docker Host

Docker Host RAM

32 GB of RAM is recommended

Docker Host CPU

The Suggestion is at least 4 cores

Docker Host Disk

A total of 512 GB of disk space is recommended.

Server mode

When installing the self-managed service in server mode. The following folder paths are used by the self-managed service. These paths cannot be changed. The following list will also provide you with information on what the folder are used for and provide an estimation of the minimum size requirements for each.

  • /etc/brainwave

Minimal Size 1GB. This is used to store among others the Brainwavefile configuration file, the keys used for the vault to encrypt secrets as well as the TLS certificates.

  • /var/lib/brainwave

Minimal size 100GB. This folder includes all Docker volumes. The different databases, encrypted secrets and in particular all source files and import files. If an internal database is use the data is stored in this folder. encrypted secrets and in particular:

  • /var/lib/docker

Minimal size 20GB. This folder contains all docker daemon data, including the images. As a rule, all images take around 5 to 6GB of disk space.

It is possible to customize the location of Docker's Daemon data directory. Please refer to Docker's official documentation for more information:

https://docs.docker.com/config/daemon/

  • /usr/local/brainwave

Minimal size 1GB. This folder contains all Docker compose configuration files and other configuration/environment files required by the application. It also contains the CLI logs.

  • /var/log/brainwave

Minimal size 10GB. This folder include the container and the batch logs. The occupied volume will depend on log retention policy.

  • /usr/local/bin

This folder will contain the 10MB Identity Analytics cli tool, named brainwave.

OS and Software

Debian 11 (stable) or Ubuntu Server 22.04 (LTS)

Docker Engine version 20.10 Please refer to the following documentation for more information :

Docker Compose plugin must be installed.


External Database Requirements

To prepare the environnement to use an external database, it is required to:

  • Create 3 users: igrc, activiti and auditlog
  • Create 1 schema by user. It should match the user name. Each user should own its corresponding schema
    • The igrc user should own the igrc schema
    • The activiti user should own the activiti schema
    • The auditlog user should own the auditlog schema

Visit the Configuration UI at <hostname>/config to finalize the configuration of the external database:

The standard requirements are to be followed when sizing the database:

Database best practices

Data base initialization

When using an external database it is possible configure the initialization of the schemas directly in the /config webpage.

To initialize the database manually, download the SQL scripts from this direct link (it is required to be authenticated for the following link to work):

https://repository.brainwavegrc.com/Brainwave/-/packages/generic/brainwave_database_scripts/1.2

  1. Initialize the igrc schema by connecting as the igrc user and execute the script in file 100-ledger.sql
  2. Initialize the activiti schema by connecting as the activiti user and execute these 3 scripts depending on the system:
  • 200-activiti.postgres.create.engine.sql or 200-activiti.sqlserver.create.engine.sql
  • 210-activiti.postgres.create.identity.sql or 210-activiti.sqlserver.create.identity.sql
  • 220-activiti.postgres.create.history.sql or 220-activiti.sqlserver.create.history.sql
  1. Initialize the auditlog schema by connecting as the auditlog user and execute the script in file 300-auditlog.sql

Postgres Example

An example of initializing a postgresql database using psql:

export PGPASSWORD="<igrc-password>"
psql -h dbhostname -d brainwave -U igrc -p 5432 -f 100-ledger.sql

export PGPASSWORD="<activiti-password>"
psql -h dbhostname -d brainwave -U activiti -p 5432 -f 200-activiti.postgres.create.engine.sql
psql -h dbhostname -d brainwave -U activiti -p 5432 -f 210-activiti.postgres.create.identity.sql
psql -h dbhostname -d brainwave -U activiti -p 5432 -f 220-activiti.postgres.create.history.sql

export PGPASSWORD="<auditlog-password>"
psql -h dbhostname -d brainwave -U auditlog -p 5432 -f 300-auditlog.sql

MS SQL Server Example

SQLCMD

You can run the scripts using sqlcmd, for example:

sqlcmd -H dbhostname -d brainwavedb -U igrc -P <igrc-password> -i 100-ledger.sql -o 100-result.rpt
sqlcmd -H dbhostname -d brainwavedb -U activiti -P <activiti-password> -i 200-activiti.sqlserver.create.engine.sql -o 200-result.rpt
sqlcmd -H dbhostname -d brainwavedb -U activiti -P <activiti-password> -i 210-activiti.sqlserver.create.identity.sql -o 210-result.rpt
sqlcmd -H dbhostname -d brainwavedb -U activiti -P <activiti-password> -i 220-activiti.sqlserver.create.history.sql -o 220-result.rpt
sqlcmd -H dbhostname -d brainwavedb -U auditlog -P <auditlog-password> -i 300-auditlog.sql -o 300-result.rpt
SQL Server Management Studio

Or you can add the following at the top of the SQL scripts to run them as the correct user in MS SQL Server:

EXECUTE AS USER = '<LOGIN>';
USE "<DATABASE>";

Where <DATABASE> is the name of your database, and <LOGIN> the login for the correct user:

  • For 100-ledger.sql, <LOGIN> is: igrc
  • For 200-activiti.*.sql, <LOGIN> is: activiti
  • For 300-auditlog.sql, <LOGIN> is: auditlog

You can also choose to directly connect with the correct user:
