Database Requirements

The supported versions are Oracle 12c, 18c and 19c - 64 bit

Warning: Oracle Real Application Clusters (RAC) is not supported, especially when configured for automatic load balancing between nodes where a write on one node will need to be replicated on the other nodes.

The character set of the database must be AL32UTF8 (UTF8).

In order to find out what exact Oracle edition/version is actually installed:
sqlplus.exe SYS@<DB-NAME> as SYSDBA
select banner from v$version where BANNER like '%Edition%';

In order to find out how much memory is actually available to the Oracle database, it is important to first understand how Oracle's memory is configuration and used:

§ The actual available System Global Area (SGA) memory can be found using:
sqlplus.exe SYS@<DB-NAME> as SYSDBA
show sga;
select * from v$sga;
select * from v$sgainfo;

§ The actual available Program Global Area (PGA) memory can be found using:
sqlplus.exe SYS@<DB-NAME> as SYSDBA
select * from v$pgastat;

In order to find out how much processing CPU/Cores is actually available to the Oracle database, query the table v$parameter for the value of cpu_count, or query the table v$license as follows:
sqlplus.exe SYS@<DB-NAME> as SYSDBA
select * from v$license;
