Technote (troubleshooting)

Error occurred when deleting temporary VFP files: ODBC Error (2)


There are other potential causes of this (or similar) errors.

  • TIP: See separate IBM Technote #1365329 for more examples.

This Technote specifically relates to the scenario where the small 32-bit portion of the Controller server (the FoxPro components) cannot locate a 32-bit Oracle database client.


Both of the following are true:

  • Customer using 64-bit version of Controller server software (i.e. Controller 10.2 or later)
  • Controller application server only has 64-bit version of Oracle client installed on Controller application server.

Resolving the problem

Install 32-bit version of the same Oracle client on the Controller application server.


Assuming that the customer has installed the Oracle 11G rel2 64-bit client already, then now install the Oracle 11G rel2 32-bit client.

  • TIP: For full details of how to do this, see separate IBM Technote #1656559.
