[cx-oracle-users] Choosing client libraries

[<pw...@re...>]

How can I know, at runtime, with which version of Oracle libs my cx_Oracle is linked?  

>>> print cx_Oracle.version
HEAD
>>> print cx_oracle.apilevel
2.0
>>> print cx_oracle.buildtime

I am confused by your statement that cx_Oracle is linked to a specific Oracle client.  If I have Oracle 8.1 client in the PATH when I run my Python script using cx_Oracle I can access an Oracle 8.1.7 running on an AIX box.  If I have the Oracle XE directory in the PATH, I can access the Oracle 10g XE running on the local machine.

With respect to the suggestion that cx_Oracle have a set of redirection calls to connect with the Oracle libs, I do not think that the overhead of a function call will be significant.
