Hi,

When in run my perl script i am getting the follwing error:
ORA-1019: unable to allocate memory in the user side (probably a symptom
of a deeper problem)

In one of the solutions it said: You are using the OCI8 driver in an
Oracle7 client installation. Use the OCI7 driver.

How do I change OCI8 driver to OCI7 driver? I having 9.2.0.5 on my
machine.Is it available with this database or should I download.

Thanks,
Nayana
