Depending on the virtual machine, the actual memory required may be higher.
This setting is persistent and affects all connections as there is only one cache per database.
Using a very small value (specially 0) will reduce performance a lot.
This setting only affects the database engine (the server in a client/server environment).
It has no effect for in-memory databases.

<ul><li>When a domain (user defined data type) contained a user defined function, the database could not be opened.
</li><li>CAST('011' AS INT) will no longer use decode the value as an octal number (using Integer.decode) but now use Integer.parseInt.
The same logic applied to byte, short, and long. This also means that trying to convert hex numbers (0x...) with CAST now fails.
