Integrated Replicat in Goldengate

Integrated Replicat or also known as Inetgrated Deliver has been introduced from 11.2.0.4 onwards that means it is also available in 12C, In integrated mode, the Replicat process leverages the apply processing functionality that is available within the Oracle database. In this mode, Replicat operates as follows:

# Reads the Oracle GoldenGate trail.

# Performs data filtering, mapping, and conversion.

# Constructs logical change records (LCR) that represent source database DML transactions (in committed order). DDL is applied directly by Replicat.

# Attaches to a background process in the target database known as a database inbound server by means of a lightweight streaming interface.

# Transmits the LCRs to the inbound server, which applies the data to the target database.


Below is an image which lists the example of an integrated apply with 2 Apply Servers

## This error message clearly specifies MAP command not finished with semi- colon, so below is how we fixed it :-

## Now you will see that semicolon is clearly mentioned :-

Errors in Goldengate Scenario 2

# Scenario 2

WARNING OGG-01223  TCP/IP error 111 (Connection refused), endpoint: node4.example.com:7907.

INFO    OGG-01971  The previous message, 'WARNING OGG-01223', repeated 2 times.


Whenever there is problem with extract always check whether it is able to capture the records or not, this will be done by stats extract command from GGSCI prompt

GGSCI (node4.example.com as ogguser@amer) 42> stats extract ext1

Sending STATS request to EXTRACT EXT1 ...

No active extraction maps.

## this means that extract is not able to capture the records as of now

We check the extract report file in location

/u01/app/oracle/product/ogg_src/dirrpt

and the report file name is EXT1.rpt

Below is the error details :-

2015-09-26 17:31:20  WARNING OGG-01223  TCP/IP error 111 (Connection refused), endpoint: node4.example.com:7907.

## After reading the above error message, we came to know that the MGR port number was not correct in extract parameter file, so after correcting it we are able to solve it, lets check how
