Oracle 12c automatically renaming index with prefix IDX$$_

edited Nov 17, 2016 4:00AM in Database Administration (MOSC) 1 commentAnswered

Hello,

we have observed since some weeks ago a strange behavior with some indexes in a particular schema of one of our Oracle 12c databases.

Some indexes seem to be inexplicably and (apparently) randomly renamed without our DBAs intervention, with the new name starting with prefix "IDX$$_" followed by a random alphanumeric string.

The index is created with the original name "idx_messages_messageread", in the schema named "atacprotocollo".

The script definition remains the same after the new name is automatically assigned.

An example of the renamed index is in the following picture.

Any hints to the possible cause of such behavior?
