DBlink problem from Oracle to Postgres: ERROR current transaction is aborted

in Database Networking (MOSC)

Hello everyone,

I'm having the same problem with this discussion https://community.oracle.com/mosc/discussion/4549492/problem-with-database-link-from-oracle-to-postgres but seem like from this we don't have the final solution yet.

I have 2 DBs from different machines:

  • Postgres DB running on a docker:
    • OS: Debian GNU/Linux 11 (bullseye).
    • psql (PostgreSQL) 15.2 (Debian 15.2-1.pgdg110+1)
    • From this docker I already public the port 5432
    • From Oracle machine, I can do "telnet <postgres-db-ip> 5432"
  • Oracle DB machine
    • OS: This is an old machine running CentOS6
    • I manually installed
      • postgresql-odbc: version 08.04.0200-1.el6
      • postgresql12-server-12.18-1PGDG.rhel6.x86_64.rpm + postgresql12-libs-12.18-1PGDG.rhel6.x86_64.rpm --> all the needed libraries are installed in /usr/pgsql-12/lib/

Howdy, Stranger!
