I'm trying to create an initial snapshot on my oracle 11g database and I encounter the following error during the snapshot process.

I think the issue is MGMT_DELTA_SUMMARY_ERRORS is a nested table in Oracle and the nested table is created by the following sql
CREATE TABLE SYSMAN.MGMT_DELTA_COMP_SUMMARIES
(
DELTA_COMP_GUID RAW(16),
COLLECTION_TYPE VARCHAR2(64 BYTE),
DIFFERENT_COUNT INTEGER,
LEFT_COUNT INTEGER,
RIGHT_COUNT INTEGER,
ERRORS SYSMAN.VARCHAR2_TABLE,
CONSTRAINT COMP_SUMMARY_PK
PRIMARY KEY
(DELTA_COMP_GUID, COLLECTION_TYPE)
USING INDEX
TABLESPACE SYSAUX
ENABLE VALIDATE
, CONSTRAINT COMP_DELTA_SUM_FK
FOREIGN KEY (DELTA_COMP_GUID)
REFERENCES SYSMAN.MGMT_DELTA_SAVED_COMPARISON (DELTA_COMP_GUID)
ON DELETE CASCADE
ENABLE VALIDATE
)
NESTED TABLE ERRORS STORE AS MGMT_DELTA_SUMMARY_ERRORS
TABLESPACE SYSAUX
LOGGING
NOCOMPRESS
NOCACHE;
-- There is no statement for index SYSMAN.SYS_C006479.
-- The object is created when the parent object is created.
I tried to add the oracle schema SYSMAN in the exclude.schema.list in the connector configuration but the capturing table step still tries to read the table. I need to rollback to 1.8.1 to workaround the issue.
What Debezium connector do you use and what version?
1.9.5
What is the connector configuration?
Oracle Connector Debezium
What is the captured database version and mode of depoyment?
(E.g. on-premises, with a specific cloud provider, etc.)
Oracle 11.2.0.4 on premise
What behaviour do you expect?
<Your answer>
What behaviour do you see?
<Your answer>
Do you see the same behaviour using the latest relesead Debezium version?
(Ideally, also verify with latest Alpha/Beta/CR version)
I tried to use 1.9.6 but i got a different error not related to this.
Do you have the connector logs, ideally from start till finish?
(You might be asked later to provide DEBUG/TRACE level log)
