About Connection.Ping method when Direct Mode

[ysyang99]

Hello,

I use ODAC 10.1.4 and Delphi 2009
Connection.Ping call procedure TOCIConnection.Ping of oraClasses.pas file.

if Direct mode, execute query "Begin Null; End;"
Can I do direct socket communication instead of query execution?
Can I provide the OCIPing method like OCI8.OCIPing when Direct mode?

Thanks

Please explain what exactly is the inconvenience of implementing the TOCIConnection.Ping method using execute query "Begin Null; End;" ?
