We’re slowly migrating our DB servers to Oracle Linux 7 and at the same time we’ll upgrade ArcServe 16/16.5 backup software to version 17.5. Unfortunately, the information that we found on the web regarding support for Oracle Linux 7.x is not consistent with the readme document that comes with the media.
Here is what official ArcServe Backup compatibility matrix is saying about OEL7 support:

And below, you’ll see what we got during agent installation. We believe that this inconsistency is due to the poor installation script maintenance (apparently updated in 2015). The installation of the agent 17.5 (+ mandatory patch 802!) on Oracle Linux 7.4 was a breeze .

$ lsb_release -d
Description:    Oracle Linux Server release 7.4

$ su - root
# mkdir /media/arcserve
# mount -t iso9660 /dev/cdrom /media/arcserve
# cd /media/arcserve/Arcserve_Backup/DataMoverandAgent/Linux

./install

That’s it. We can start or stop the agent with the usual commands:

Start and stop the agent:
 
sudo  /etc/init.d/bab_agent stop
sudo /etc/init.d/bab_agent start

or simply:

caagent stop
caagent start

You should also download and apply patch P00000802.zip before putting agent in production:

Download patch P00000802.zip from ArcServe support.

# cd /home/alesk/Downloads/ArcServe-Patch/
# unzip P00000802.zip
# caagent stop
Shutting down Arcserve Backup Universal Agent process...Down.

-- backup original file
# cp -p /opt/Arcserve/ABuagent/uagentd /opt/Arcserve/ABuagent/uagentd.BkpP00000802

# cp uagentd /opt/Arcserve/ABuagent
# caagent start

If you have firewall enabled, then you’ll have to add port 6051 to the exception list:

sudo firewall-cmd --permanent --zone=public --add-port=6051/udp
sudo firewall-cmd --permanent --zone=public --add-port=6051/tcp
sudo firewall-cmd --reload
