In the second part of this article, i will show how delphix masking can help ensure referential integrity consistency across different targets even when using different masking engines (5.2 an up).
In my demonstration case i will be using the (oracle) employees table and a copy of the same table on (mysql).
Scenario I : using the same engine
Check the content of both tables before masking.
[oracle@linuxsource ~]$ . oraenv
ORACLE_SID = [demovdb] ?
The Oracle base remains unchanged with value /u01/app/oracle
[oracle@linuxsource ~]$ sqlplus / as sysdba

Let's mask both tables using the same masking algorithms with those rules:
- Firstname column using firstname sl algorithm
- Lastname column using lastname sl algorithm
- City column using city with null replacement algorithm
The result after masking both tables is as follows.
[oracle@linuxsource ~]$ . oraenv
ORACLE_SID = [demovdb] ?
The Oracle base remains unchanged with value /u01/app/oracle

As you can see we ended up with the same masked values for both tables even the data is located in different databases
Scenario II : using different engines
To ensure the masking consistency in case of multi-engines deployment we have to use the same key.
Let's sync the masking key between our engines.
- exporting the key from the first engine
[root@linuxtarget masking_v2_api]# sh key_sync.sh

We ended up with the same values even using different masking engines because of key sync and same algorithm usage.
