Operating system your database runs on[edit]

You can use the dbms_utility.port_string function to determine on what hardware platform, operating system and TWO TASK PROTOCOL version your Oracle database is running on. The specification for this function follows:


Here are some examples:

SQL> SELECT dbms_utility.port_string FROM dual;
SQL> VAR portstr VARCHAR2(100)
SQL> EXEC :portstr := dbms_utility.port_string;
PL/SQL procedure successfully completed.
SQL> PRINT portstr

In the above example the platform is IBMPC, the OS is WIN_NT and the Two Task protocol version is 8.1.0.

Some of the other possible port string values:

  • VAX/VMS-
  • DEC Alpha OSF/1, r1.1-8.1.0
  • SVR4-be-64bit-8.1.0
