Try to register NG server in OA. Task Deploying webserver X.X.X.X fails with the following output:

Destination host 'your_hostname' (#1), IP 'IP_ADDRESS_OF_MN' : truepath /var/lib/pgsql/9.1/data/pg_hba.conf: No such file or directory (errno 2).

Indeed, there is no such file on MN, because OA DB is located on standalone host.


Program issue POA-88380: "NG node registration fails if OA DB is on another host".


Please contact your Technical Account Manager or Pooled Technical Associates team ( to trace the status of the issue. Please use the following workaround in order to fix the issue:

  1. Create appropriate files and directory on MN:

    [root@osscore ~]# mkdir -p /var/lib/pgsql/9.1/data/
    [root@osscore ~]# touch /var/lib/pgsql/9.1/data/pg_hba.conf
    [root@osscore ~]# echo -e '#!/bin/sh\n exit 0' > /etc/init.d/postgresql-9.1
    [root@osscore ~]# chmod +x /etc/init.d/postgresql-9.1
  2. Run the task again. It should be completed successfully.

  3. Other tasks in the same queue can fail with the following output:

    IP address X.X.X.X is already configured for host XXX.

    In this case go to PCP > Infrastructure > Hardware Nodes > unnecessary_node > Summary and click Delete button.
