​

Technote (troubleshooting)


Problem(Abstract)

DataStage clients cannot connect to the server after a reboot of the engine tier.

Symptom

DSEngine does not start automatically on RHEL7 even though ds.rc links have been set up under /etc/init.d and /etc/rc[2-5].d.

Cause

In Red Hat Enterprise Linux 7, systemd replaces upstart as the default init system.

Environment

RHEL 7

Resolving the problem

The following steps work around the issue. Root access is necessary.


For non-itag installs:---

Create a file "/usr/lib/systemd/system/ds.rc.service" with the following content.

[Unit]
Description=DataStage Engine
Requires=basic.target

[Service]
Type=forking
RemainAfterExit=yes
ExecStart=/etc/init.d/ds.rc start
ExecStop=/etc/init.d/ds.rc stop

[Install]
WantedBy=multi-user.target

Then execute the following commands to enable autostart of DataStage Server Engine.

# systemctl enable ds.rc.service
# systemctl start ds.rc.service

To disable autostart of DataStage Server Engine.

# systemctl disable ds.rc.service


For ITAG Install:--

Create a file "/usr/lib/systemd/system/{itag}ds.rc.service" with the following content.

[Unit]
Description=DataStage Engine
Requires=basic.target

[Service]
Type=forking
RemainAfterExit=yes
ExecStart=/etc/init.d/{itag}ds.rc start
ExecStop=/etc/init.d/{itag}ds.rc stop

[Install]
WantedBy=multi-user.target

Then execute the following commands to enable autostart of DataStage Server Engine.

# systemctl enable {itag}ds.rc.service
# systemctl start {itag}ds.rc.service

To disable autostart of DataStage Server Engine.

# systemctl disable {itag}ds.rc.service

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
