Since v16.4, Opentext doesn’t provide a “preconfigured” Docker image for Documentum running on Oracle. If you want to use a docker image running PostgreSQL you can use the same procedure as described for Full docker CS7.3 PostgreSQL + D2 4.7 installation guide or DCTM 7.3 PostgreSQL with Docker install guide, and you should not have too many issues 😀

This guide will help you setup a VM running CentOS 7 where we will install Oracle (Express) and docker, and will be building a Documentum image. We will split the build in several images to avoid having to do a full rebuild if something goes wrong 😀

Environment

Host:
Windows 10 x64 8GB RAM
VMware Workstation Player 12

Guest:
CentOS 7 x64 25GB HD 4GB RAM 2 cores
Docker 1.13.1

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 vm-dctmdocker, configure the network and set the root password.

Oracle XE setup

• I copied every installer in $DOCUMENTUM/installers, so:

[dmadmin@vm-dctmdocker opt]$ sudo mkdir documentum
[dmadmin@vm-dctmdocker opt]$ sudo chown dmadmin.dmadmin documentum
[dmadmin@vm-dctmdocker documentum]$ mkdir installers
[dmadmin@dctmdocker installers]$ cp /mnt/hgfs/dctm72/oracle-xe-11.2.0-1.0.x86_64.rpm/Disk1/oracle-xe-11.2.0-1.0.x86_64.rpm .

• Install needed libraries, run installer, run configuration tool (remember to change the default 8080 port to something else to avoid conflicts with tomcat if you want to use an application server):

[dmadmin@vm-dctmdocker installers]$ sudo yum install libaio bc
[dmadmin@vm-dctmdocker installers]$ sudo rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
[dmadmin@vm-dctmdocker installers]$ sudo /etc/init.d/oracle-xe configure

• Launch sqlplus to enable remote access and remove the password expiration:

[dmadmin@vm-dctmdocker installers]$ . /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh

[dmadmin@vm-dctmdocker installers]$ /u01/app/oracle/product/11.2.0/xe/bin/sqlplus system
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
quit

Docker setup

We’ll just install docker, adding dmadmin user to the docker group so we don’t need to use sudo every time we want to run the “docker” command

[dmadmin@vm-dctmdocker installers]$ sudo yum install docker
[dmadmin@vm-dctmdocker installers]$ sudo usermod -a -G docker dmadmin
[dmadmin@vm-dctmdocker installers]$ systemctl restart docker.service

Centos docker image setup

This base image will just add required packages and minor configurations:

[dmadmin@vm-dctmdocker installers]$ docker pull centos
[dmadmin@vm-dctmdocker installers]$ docker build –no-cache -f ./customCentosDockerfile -t custom_centos .

customCentosDockerfile:

FROM centos

Documentum base image setup

This image will install Documentum binaries and Oracle client:

[dmadmin@vm-dctmdocker installers]$ docker build –no-cache -f ./dctmcentosDockerfile -t centos_dctm .

Additional information

Custom scripts created for the install:

• startup-dctm.sh: updates hostname, dfc.properties, runs dm_crypto_boot and starts the repository services.
• fix_tnsnames.sh: updates tnsnames with Oracle server public IP (which in this example is hardcoded)
• configProperties.properties: Standard silent install script

If something goes wrong at some point, remember you’ll need to:

• Delete docker dangling containers
• Delete user created on database by the installer
• Delete tablespaces created on database by the installer
