Error E021
Message
[DBC-E021] No AWR or Statspack detected for %s (try --license-ok)
Explanation
DBCollect could not detect prior AWR usage and no statspack configuration for this instance.
Solution:
(Only if you have Diagnostics Pack license for the host!): Run dbcollect with --license-ok
Solution 2:
Setup Statspack, wait for at least a week to generate data and rerun (if you do not have the Diagnostics license)
Solution 3:
Run dbcollect with --ignore to skip performance data for all databases completely. Beware that this may lead to incomplete workload assessment results.
