No, for CN BRM 12, you need to master the following as well:

Docker
Kubernetes
Helm
NoSQL
Grafana etc

There are 2 types of plugins in batch pipeline:

Data Plugins represented as DAT_XXX

Functional Plugins represented as FCT_XXX

Key BRM acronyms:

CM - Connection Manager
DM - Data Manager
FM - Facility Module
EM - External Manager
UEL - Universal Event Loader
REL - Rated Event Loader
etc.

To customise BRM, we customise Policy FMs.

To customise Batch Pipeline, we customise iScripts and/or iRules.

BRM is opcode driven whereas Pipeline is plug-in driven.

Testnap script example:

$ vi Khan.nap <enter>

r << Samiullah 1
0 PIN_FLD_POID POID [0] 0.0.0.1 /account 583917402 1
Samiullah
xop PCM_OP_READ_OBJ 0 1
<esc>:wq!

$ ./testnap Khan.nap <enter>

Output

0 PIN_FLD_POID POID [0] 0.0.0.1 /account 583917402 1

.
.
.

BRM opcode:

in C policy file is executed through:

PCM_OP (conn, opcode, flag, ifl, ofl, error_buffer)

in testnap, through:

xop PCM_OP_READ_OBJ 0 1

in Developer Center, through:

Opcode Workbench

BRM opcodes are of the following types:

Base opcode
Example:
PCM_OP_SEARCH

Standard/System opcode
Example:
PCM_OP_AR_REVERSE_WRITEOFF

Policy opcode
Example:

PCM_OP_AR_POL_REVERSE_WRITEOFF

BRM opcode is a C function implemented as a C macro.

PCM_OP_CREATE_OBJ

Output = Create_Obj (Input)

Here

Output = POID = 0.0.01 /account 12345 0

Input = POID = 0.0.0.1 /account -1 0

Create_Obj = PCM_OP_CREATE_OBJ

BRM Flist is a field-value pair.

Example:

PIN_FLD_NAME “Samiullah Khan”

Here field name is PIN_FLD_NAME, field type is string and the field value is “Samiullah Khan”.

Data flows in BRM in terms of flists only.

You name any big CSP/Telco Operator in the world they must be using BRM. Such is the Powerful Reach of BRM.

BRM is an opcode driven application.
