I have a query which intermittently returns the following error: @all_resolved_calls siebel.W_ENTLMNT_D T7967, * ERROR at line 153: ORA-01410: invalid ROWID My first suspicion was that I had a corrupted index. When I ran "analyze table .. validate structure cascade" to verify that all entries in the table's indexes point to valid rowids I got no errors. My environment is Oracle 8.1.7.4 running on SunOS 5.9. Where else should I be looking, or should I just blindly rebuild all four indexes on the table.
