      What Debezium connector do you use and what version?

      2.4.0.Alpha2: Oracle-source and jdbc-sink

      What is the connector configuration?

      What is the captured database version and mode of depoyment?

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

      source db: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

      target db:PostgreSQL 13.2 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5), 64-bit

      What behaviour do you expect?

      <Your answer>

      What behaviour do you see?

      I'm getting error when I add float column to source table (Oracle DB)

      Initial source table ddl:

      CREATE TABLE "DEBEZIUM"."GBC_TBL_SERVICECALL_NC27"    (	"ID" NUMBER(19,0) NOT NULL ENABLE, 	"CREATION_DATE" TIMESTAMP (6) NOT NULL ENABLE, 	"CLAIM_TRANSFERDATE" DATE, 	"TITLE" VARCHAR2(4000 CHAR), 	"CLIENT_EMAIL" VARCHAR2(255 CHAR), 	"CLAIM_SUMRETURN" FLOAT(126), 	 PRIMARY KEY ("ID")  USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS   STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)  TABLESPACE "USERS"  ENABLE   ) SEGMENT CREATION IMMEDIATE   PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255  NOCOMPRESS LOGGING  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)  TABLESPACE "USERS" ;  

      Source table has float column and source and sink connector work correct (I've checked insert and delete operations).

      But when I add a new float column, I'm getting an error in sink connector.

      Source db (Oracle):

       ALTER TABLE DEBEZIUM.GBC_TBL_SERVICECALL_NC27 ADD (NEW_FLOAT FLOAT);
 INSERT INTO DEBEZIUM.GBC_TBL_SERVICECALL_NC27 
  VALUES(3, SYSTIMESTAMP, SYSDATE, 'TITLE 1', 'EMAIL 1', 111.22, 222.33)

      New source table ddl (Oracle):

      CREATE TABLE "DEBEZIUM"."GBC_TBL_SERVICECALL_NC27"    (	"ID" NUMBER(19,0) NOT NULL ENABLE, 	"CREATION_DATE" TIMESTAMP (6) NOT NULL ENABLE, 	"CLAIM_TRANSFERDATE" DATE, 	"TITLE" VARCHAR2(4000 CHAR), 	"CLIENT_EMAIL" VARCHAR2(255 CHAR), 	"CLAIM_SUMRETURN" FLOAT(126), 	"NEW_FLOAT" FLOAT(126), 	 PRIMARY KEY ("ID")  USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS   STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)  TABLESPACE "USERS"  ENABLE   ) SEGMENT CREATION IMMEDIATE   PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255  NOCOMPRESS LOGGING  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)  TABLESPACE "USERS" ;

      In target db (Postgres) new column was not added.

       

      Maybe this issue has something to do with the problem DBZ-6686

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

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

      2.4.0.Alpha2

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

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

      yes
