ORACLE: system. Data. oracleclient requires Oracle client software version 8.1.7 or greater.

Recently, Oracle has been used in projects. This problem often occurs in system. Data. oracleclient requires Oracle client software version 8.1.7 or greater. Let us share the solution to this problem:

Client Server: Oracle 9. You only need to grant the Authenticated Users group the permission to access the Oracle Home Directory.

Local server: Oracle 9i. According to the above statement, it is basically impossible to solve the problem. after a long time of exploration, we installed the Oracle for. Net driver.

At that time, Oracle for was installed without notice that the client server was Oracle 9.. Net driver. As a result, the entire Oracle service is deprecated. It can only be uninstalled and re-installed, and the directory permission is set. It is also possible that I have installed a 9i driver, the version is too high.

At the beginning, the local server was able to set permissions on the Internet and restart permissions without stopping them. The supervisor did not solve the problem. Later, I went to the Internet to get the driver and tried it. All right, it turns out to be a driver problem... It's really tough.
