- set variable RDBBDR HOME in .rdbbdr_env.sh
- soruce environment file .rdbbdr_env.sh
- installing TCapture logical decoding library under /usr/pgsql-10/lib

examples.
1- echo "export RDBBDR=/var/lib/pgsql/scripts/mycode/rdbbdr" > .rdbbdr_env.sh
2-. .rdbbdr_env.sh
3-echo $RDBBDR
4-/var/lib/pgsql/scripts/mycode/rdbbdr
5-cd $RDBBDR
6-cp ./rdbbdr/lib/rdb_decoder/rdblogdec.so /usr/pgsql-10/lib/

Configuring a primary database node

check out the Adding a Primary node in TCapture section. !

PostgreSQL hba Configuration

By default, PostgreSQL is not configured to allow incoming connections from remote hosts. To enable incoming connections, first set the following line in postgresql.conf:

listen_addresses = '*'

And in pg_hba.conf, add a line such as the following to allow incoming connections:

host    all             all             <ip address>/<subnet>            md5

For example, to allow incoming connections from any host:

host    all             all             0.0.0.0/0            md5

Running PostgreSQL

To run the PostgreSQL server in the background, use the pg_ctl driver and point it to your newly initialized data directory:

pg_ctl -D <data directory> -l postgresql.log start

Now you’re ready to start using TCapture check out the Adding a Primary node in TCapture section. !
