# PFA Naming guidelines

As PFA should be a "flexible" architecture we provide only guidelines and best practices concerning the naming convention of the several database components.

## PGOME directories

| Directory                     | Purpose                                               |
| ----------------------------- | ----------------------------------------------------- |
| /u01/app/postgres/product/94/ | PostgreSQL software sub tree for release 9.4 products |

## Mount points

It is important to consider that each mount point represents a separate filesystem. In some cases, it should even be a filesystem stored of different disks (i.e filesystems for different redo log members). Below a list of components which should be separated over different physical disks:

**Strongly advised:**

* PostgreSQL software / PostgreSQL databases
* PostgreSQL admin files / PostgreSQL databases
* WAL files
* PostgreSQL database backup files
