How consume data replicated through Goldengate in parallel mode ?

user11934310 Member Posts: 3 Red Ribbon


Today we use Goldengate in coordinated mode to replicate data on our data hub.

Our consumers programs read data from low CSN to max CSN.

Consumers programs use the Goldengate checkpoint table to obtain the CSN used to define the max CSN until where the data are usable.

For that we get CSN from LOG_CMPLT_CSN column.

Now we want use the last Goldengate version in parallel mode.

To consume data like coordinated mode, we want to use the lwm_csn column to get the max window until where the data are usable.

The questions are:

Is it the good column to do that ?

If yes, Is the CSN of the consumed transactions less than or equal to the CSN value of the lwm_csn column?

Checkpoint table generated by Goldengate in parallel mode:

create table CHECKPOINT


 applier_id       NUMBER(2) not null,

 lwm_csn        VARCHAR2(128 BYTE),

 seqno         NUMBER(10),

 rba          NUMBER(19),

 log_bsn        VARCHAR2(128 BYTE),

 trail_name       VARCHAR2(250 BYTE),

 trail_id        NUMBER not null,

 key          NUMBER not null,

 version        NUMBER,

 transaction_table_0_id VARCHAR2(10 BYTE),

 transaction_table_1_id VARCHAR2(10 BYTE)


Thanks a lots for your answers.
