The GoldenGate Veridata Agents execute the database related requests to compare source and target database rows on behalf of the Veridata Server.
At a minimum we need to install two agents – one to retrieve source rows and one to retrieve target rows from the database.
There are two types of agents – one is the Java based agent and the other is the C-Agent.
The Java Agent connects to the database using JDBC and permits data comparisons in heterogeneous environments. A Java environment JRE/JSDK is required to support this agent and a minimum java version is 1.5
We have copied the V19618-01.zip file from the Metalink E-Deilvery site and unzipped it as shown below.
dba1:/u01/ofsad2> mkdir veriagent
dba1:/u01/ofsad2> mv V19618-01.zip ./veriagentdba1:/u01/ofsad2> cd veriagent

We then need to copy the agents.properties.sample file and create a file called agents.properties as shown below. Here we are providing the port where the agent will run as well as database connection information like the listener port and SID of the database.
dba1:/u01/ofsad2/veriagent/agent> cp agent.properties.sample agent.properties
# The server.port property is the port where the Veridata agent listens
# for connection requests.
server.port=4000
# Oracle sample database connection URL^M
database.url=jdbc:oracle:thin:@redhat346:1522:gavin
server.driversLocation = drivers
server.jdbcDriver=ojdbc5.jar
database.transaction.isolation=READ_COMMITTED
[oracle@redhat346 agent]$ export JRE_HOME=/u01/oracle/jre1.6.0_18
[oracle@redhat346 agent]$ ./agent.sh start
Installing the C Agent
We first download the file V18202-01.zip from the E-Delivery web site and unpack as shown below. We then will launch the GoldenGate Command Interpretor (GGSCI) from the Veridata Agent directory location. We create the sub directories for the agent and configure a manager process for the Veridata Agent – not to be confused with the Manager process that we configured at the very beginning of the GoldenGate installation.
dba1:/u01/ofsad2/veriagent> unzip V18202-01.zip
