• Article Type: General
• Product: Aleph
• Product Version: 20

Problem Symptoms:
*

In running the AIK, the following message occurs after I select AIK: step 3:5 "Check connection to the database via listener":

The connection to the database aleph20 via listener hasn't been established yet... ...
Press Enter to continue

Cause:
See Resolution below.

Resolution:
In one case: An old Oracle account (plain "oracle"; with no "20") was causing the problem. Removing this oracle account and all oracle users, and then reinstalling worked.

In a second case: "The problem was resolved by uninstall and reinstall with a correct value in the host field."

In a third case: Defined a different database name; added the network name at the appropriate place.

In a fourth case: The configuration had some values set for RAC. (The first time through, the listener step had a choice between remote and RAC database setups. It seems that our choice (RAC) was incorrect.

In a fifth case: An old (pre-March 13, 2012) of the AIK was being used. Using the current version corrected the problem.

A sixth case: KB 16384-62721 ("After making corrections described in KB 16384-61809, AIK step 3.4 still fails") because the customer did not wait for the database to be registered with the listener.
