Bug report

For bug reports, provide this information, please:

What Debezium connector do you use and what version?

Debezium Oracle Connector 1.9.8

What is the connector configuration?

log.mining.archive.log.hours=120

log.mining.strategy=online_catalog

snapshot.fetch.size=30000

lob.enabled=true

#heartbeat.interval.ms=300000

producer.override.batch.size=8192000

producer.override.linger.ms=10

poll.interval.ms=1000

log.mining.batch.size.min=1000000

log.mining.batch.size.max=20000000

log.mining.batch.size.default=3000000

What is the captured database version and mode of depoyment?

(E.g. on-premises, with a specific cloud provider, etc.)

Oracle 19c, non CDB

What behaviour do you expect?

Alter script should add the columns on the target table

What behaviour do you see?

Failure.

Do you see the same behaviour using the latest relesead Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)

Did not verify as 1.9.8 is the Final version

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)

(
 OB_VIA_SERVICENOW_STATUS as (ONBOARDING_VIA_SERVICENOW_STATUS || ''),
 PAYROLL_WORKER_OB_VIA_SNOW as (PAYROLL_WORKER_ONBOARD_VIA_SNOW || '')
