Opentext Documentum 16.7 PostgreSQL Developer Edition

This is a step-by-step guide to install Documentum 16.7 in a Linux environment with PostgreSQL 11.


Windows 10 x64 8GB RAM
VMware Workstation Player 15

CentOS 7.7 x64 25GB HD 4GB RAM 2 cores
PostgreSQL 11
Documentum 16.7

VM Creation

Mount the CentOS 7 DVD image, boot the machine and follow the steps. You can choose to let EasyInstall do the work for you. I used minimal package install to save resources, named the machine dctm167, configured the network and set the root password as well as a “dmadmin” user.

OS Configuration

  • Install required packages:

[dmadmin@dctm167 ~]$ sudo yum -y install bash-completion kernel-devel rng-tools.x86_64
[dmadmin@dctm167 ~]$ sudo yum -y install bash-completion kernel-devel rng-tools.x86_64 policycoreutils policycoreutils-python selinux-policy selinux-policy-targeted libselinux-utils setroubleshoot-server setools setools-console mcstrans expect tcl
[dmadmin@dctm167 ~]$ sudo yum -y group install X\ Window\ System “Development Tools”
[dmadmin@dctm167 ~]$ sudo yum -y install open-vm-tools.x86_64

  • Stop and disable the firewalld service:

[dmadmin@dctm167 ~]$ sudo systemctl disable firewalld
Removed symlink /etc/systemd/system/
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[dmadmin@dctm167 ~]$ sudo systemctl stop firewalld

  • Configure entropy and allow http connections through selinux:

[dmadmin@dctm167 ~]$ sudo /sbin/rngd -b -r /dev/urandom -p /dev/random
[dmadmin@dctm167 ~]$ sudo setsebool -P httpd_can_network_connect_db 1
[dmadmin@dctm167 ~]$ sudo chkconfig rngd on

PostgreSQL Configuration

  • Install required packages:

[dmadmin@dctm167 ~]$ sudo yum -y install
[dmadmin@dctm167 ~]$ sudo yum -y install postgresql11 postgresql11-server

  • Init the DB:

[dmadmin@dctm167 ~]$ sudo /usr/pgsql-11/bin/postgresql-11-setup initdb

  • Enable and start the PostgreSQL service:

[dmadmin@dctm167 ~]$ sudo systemctl enable postgresql-11
Created symlink from /etc/systemd/system/ to /usr/lib/systemd/system/postgresql-11.service.
[dmadmin@dctm167 ~]$ sudo systemctl start postgresql-11

  • Configure the postgres user:

[dmadmin@dctm167 ~]$ sudo passwd postgres
Changing password for user postgres.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.

[dmadmin@dctm167 ~]$ su – postgres
-bash-4.2$ psql
psql (11.5)
Type “help” for help.

postgres=# \password postgres
Enter new password:
Enter it again:
postgres=# \q
-bash-4.2$ exit

  • Configure PostgreSQL:

[root@dctm167 ~]# vi /var/lib/pgsql/11/data/postgresql.conf
listen_addresses = ‘*’
port = 5432

[root@dctm167 ~]# vi /var/lib/pgsql/11/data/pg_hba.conf
host    all             all               md5
host all all ::/128 md5
host    all             all             dctm167              md5

  • Restart PostgreSQL service to apply the changes:

[dmadmin@dctm167 ~]$ sudo systemctl restart postgresql-11

phpPgAdmin Configuration

  • Install required packages:

[dmadmin@dctm167 ~]$ sudo yum -y install phpPgAdmin httpd

  • Configure phpPgAdmin:

[dmadmin@dctm167 ~]$ sudo vi /etc/httpd/conf.d/phpPgAdmin.conf

Alias /phpPgAdmin /usr/share/phpPgAdmin

# Apache 2.4
Require all granted
#Require host

# Apache 2.2
Order deny,allow
Allow from all
#Allow from
#Allow from ::1
# Allow from

[dmadmin@dctm167 ~]$ sudo vi /etc/phpPgAdmin/

$conf[‘servers’][0][‘host’] = ‘dctm167’;
$conf[‘extra_login_security’] = false;
$conf[‘owned_only’] = true;

[dmadmin@dctm167 ~]$ sudo cp /etc/phpPgAdmin/ /etc/phpPgAdmin/

  • Restart httpd service to apply the changes:

[dmadmin@dctm167 ~]$ sudo systemctl restart httpd

Now you should be able to login to the console from http://dctm167/phpPgAdmin/

ODBC Configuration

  • Install required packages:

[dmadmin@dctm167 ~]$ sudo yum -y install postgresql11-odbc.x86_64 unixODBC.x86_64

  • Configure .ini files:

[dmadmin@dctm167 ~]$ sudo vi /etc/odbcinst.ini
Description = ODBC for PostgreSQL
#Driver = /usr/lib/
#Setup = /usr/lib/
#Driver64 = /usr/lib64/
#Setup64 = /usr/lib64/
Driver = /usr/pgsql-11/lib/
Driver64 = /usr/pgsql-11/lib/
Setup64 = /usr/lib64/
FileUsage = 1
[dmadmin@dctm167 ~]$ sudo vi /etc/odbc.ini

  • Test the connection:

[dmadmin@dctm167 ~]$ isql -v MyPostgres
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
SQL> quit

Documentum server

  • Create folders:

[dmadmin@dctm167 ~]$ sudo mkdir -p /opt/documentum && sudo chown dmadmin.dmadmin /opt/documentum && mkdir /opt/documentum/product && mkdir /opt/documentum/product/16.7 && mkdir -p /opt/documentum/sw/cs

  • Install openJDK 11 (remember to remove “anon” from the list of disabled algorithms or the installer will fail to connect to the repository)

[dmadmin@dctm167 cs]$ sudo yum -y install java-11-openjdk java-11-openjdk-devel
[dmadmin@dctm167 cs]$ echo $(dirname $(dirname $(readlink $(readlink $(which javac)))))

  • Set up environment variables:

[dmadmin@dctm167 ~]$ vi ~/.bash_profile

export DM_HOME


export JAVA_HOME

export PATH

export LC_ALL


  • Reserve ports for services:

[dmadmin@dctm167 ~]$ sudo vi /etc/services
dctm167 50000/tcp # dctm 16.7 repo
dctm167_s 50001/tcp # dctm 16.7 repo

  • Create symbolic link for later (configuration program):

[dmadmin@dctm167 ~]$ sudo ln -s /usr/lib64/ /usr/lib64/

  • Configure limits.conf:

[dmadmin@dctm167 ~]$ sudo vi /etc/security/limits.conf
dmadmin – core -1

  • Run the installer:

[dmadmin@dctm167 cs]$ tar -xvf content_server_16.7_linux64_postgres.tar
[dmadmin@dctm167 cs]$ chmod 777 serverSetup.bin
[dmadmin@dctm167 cs]$ ./serverSetup.bin


Docbroker and repository

  • Create the tablespace file for the repository (dctm167):

[dmadmin@dctm167 cs]$ su –
[root@dctm167 ~]# su – postgres
-bash-4.2$ mkdir /var/lib/pgsql/11/data/db_dctm167_dat.dat
-bash-4.2$ exit
[root@dctm167 ~]# exit

  • Run the configurator:

[dmadmin@dctm167 install]$ ./



Documentum Administrator

Nothing special about this, same procedure as always. I’ve used the latest tomcat 9 to deploy running on the same openJDK 11 used for the repository:


Some notes:

  • Java is not bundled anymore, you need to install a JDK before running the installer. (Be aware of the issues with Java >1.8u201, as the “anon” algorithm has been disabled and if you choose any secure configuration you’ll face some issues while installing)
  • No lockbox!

  1. Thanks for the guide. I tried installing this but in Windows Server 2016. Unfotunately i encountered some errors on the webapp part. Whenever I enter this in the Java options Tomcat won’t start,


    Is this still necessary in Tomcat 9?


  2. Thanks for the guide.
    This is the first time I used PostgreSQL in installing Documentum (I usually use MSSQL). but my environment is running in Windows Server 2016.

    One problem though I encountered was with Tomcat, when ever I add the usual script in Java options


    Tomcat won’t start. Is this still necessary in Tomcat 9?


  3. Hi there! I’ve been trying non-stop to get this running following this bit by bit, still haven’t been able to pull it out.

    I’ve basically copied over everything you’ve written in here in a CentOS virtualized environment running Docker containers within it and still no luck, i keep getting PostgreSQL connection issues. Any clues? I could elaborate on this even deeper if needed.


    • can you get the install logs? there should be some info on the error in the container. There are 2 main logs, one is (I may remember incorrectly the paths) /opt/dctm_install/logs and the other is the install log from documentum ($DOCUMENTUM/16.7/product/install/logs)

      Remember that if you have to restart/rebuild you have to remove/purge the volumes, as the data is still there and the image is not “refreshed”


      • Okay, to be trully honest, i don’t really know how but I finally managed to get it running.
        If i need to turn container off, when I re run it, will it reinstall the whole thing or maintain what it currently has?

        There are only dumbs who ask questions, no dumb questions whatsoever. 🙂

        Thanks in advance, been having it rough for at least two weeks on this one.
