diagnostic analysis
===================
- below error is received in an 12.2 upgraded database from 11.2.0.4
  ora-600: internal error code, arguments: [kdlrci_get_inline_data], [30],
[3], [], [], [], [], [], [], [], [], []
- the cdb env is in use
- the error is seen when select on cdb_feature_usage_statistics
with
pdbs  as (select con_id, name
from v$containers where con_id != 2)
select p.name, dbid, c.name, version, detected_usages,
total_samples, currently_used,
to_char(first_usage_date,'yyyy-mm-dd hh24:mi:ss') first_usage,
to_char(last_usage_date,'yyyy-mm-dd hh24:mi:ss') last_usage,
aux_count,
to_char(last_sample_date,'yyyy-mm-dd hh24:mi:ss') last_sample,
last_sample_period,
replace((nvl(to_char(regexp_replace(substr(feature_info,0,4000),'[^!@/\.,;:<>#
$%&()_=[:alnum:][:blank:]]')),'')),'|','#') feature_detail
from cdb_feature_usage_statistics c, pdbs p
where version in
( select max(version) from cdb_feature_usage_statistics
where con_id = p.con_id  )
and c.con_id = p.con_id
and detected_usages > 0
and rownum < 9000
- if the pdbs are stopped samestatement is not trigering any error
- we managed to have the error reproduced in house with a copy of customer db
- i have creted the undo again but the error is still present
- same explain plan is seen when pds are closed and open and error still
present. when pdbs are opened and failing statement is executed px is in use
but disable it at session level and still error is present
- no additional details in the 10046 trace
