Amazon EC2 memory configuration

dhuser · 2 September 2015 10:11

Hi

I registered for a free tier EC2 instance (t2.micro) on Amazon with Ubuntu 14.04 AMD64 I have set it up according to the DHIS2 implementation manual. I'm aware that this low hardware specifications are not ready for national use, I'd like to use it as prototyping resource. However, the server responds to pings but is not accessible through the browser. I suspect the memory configuration. Please find the relevant configurations / error messages in below. RAM: 1GB memory CPU: 1 CPU, spike balancing (t2.micro tier from amazon) Disk: 20GB Basically, I just divided the RAM specs from the implementation manual (2x 8GB) for each attribute by 16 (I have 1GB). after restarting tomcat:

Hi David,

1 GB is probably pushing it a bit, AFAIK. Possible, but not too easy…2 GB should be fine.

Are you sure that Tomcat actually shut down ?

Be sure Tomcat is dead by invoking ps -ef | grep tomcat and killing any processes(es) which may be running, and then start it again. If you get that memory leak error again, then something else is not right.

Having said that, I agree with Knut. 1GB will really be pushing it, but you might be able to get it to work.

Regards,

Jason

Hi David,

INFO: Pausing ProtocolHandler [“http-bio-8080”]

you are running on port 8080, this might be related to firewalls on aws. Try running on port 80 (conf/server.xml).

Alternatively check if firewalls are active and blocks 8080.

regards,

Lars

At BAO we’ve found we could only reliably support DHIS 2 with a minimum of 2GB.

Are you sure that Tomcat actually shut down ?

Be sure Tomcat is dead by invoking ps -ef | grep tomcat and killing any processes(es) which may be running, and then start it again. If you get that memory leak error again, then something else is not right.

Having said that, I agree with Knut. 1GB will really be pushing it, but you might be able to get it to work.

Hi David,

1 GB is probably pushing it a bit, AFAIK. Possible, but not too easy…2 GB should be fine.

Hi

I registered for a free tier EC2 instance (t2.micro) on Amazon with Ubuntu 14.04 AMD64 [http://aws.amazon.com/ec2/instance-types/](http://aws.amazon.com/ec2/instance-types/)

I have set it up according to the DHIS2 implementation manual.

I'm aware that this low hardware specifications are not ready for national use, I'd like to use it as prototyping resource. However, the server responds to pings but is not accessible through the browser. I suspect the memory configuration. Please find the relevant configurations / error messages in     red below.



**Hardware:**

RAM: 1GB memory

CPU: 1 CPU, spike balancing (t2.micro tier from amazon)

Disk: 20GB



Basically, I just divided the RAM specs from the implementation manual (2x 8GB) for each attribute by 16 (I have 1GB).

Hi David

The log file does seem to indicate that the startup was successful.
It does look like an orderly shutdown rather than any sign of
out-of-memory exceptions. Which happens about 1 minute after the
successful startup. Did you shut it down yourself or it just
collapsed without you doing anything?

if you started it then couldn't access it, so you shut it down, it
might well be related to a firewall issue as per Lars's suggestion.

Don't pay the SEVERE memory leak exceptions too much mind. These are
important if you are starting and stopping individual web applications
in a (continuous) running tomcat. They don't mean much at all if you
are bringing down the whole tomcat server.

Running in 1G is a challenge and you might be able to get dhis up and
running but barely functional. There are a few things to try:

1. Don't try to optimize postgres settings at all. Let it run in the
bare minimum out-of-the-box default. If I add up all your java and
postgres allocations you are already over 1G without even considering
kernel memory and the like.

2. You could (in server.xml) reduce the max size of tomcat threadpool
to maybe 4 or 5.

3. There are some dhis internal threadpool configs you can also
reduce but its a bit more fiddly (and I don't have the details at
hand)

The sensible thing (depending on what you are trying to achieve) is to
increase your available RAM to 2G or more. getting it to run in 1G is
an interesting challenge which I've achieved once or twice but really
not all that useful.

Hi David,

INFO: Pausing ProtocolHandler ["http-bio-8080"]

you are running on port 8080, this might be related to firewalls on aws. Try
running on port 80 (conf/server.xml).

Alternatively check if firewalls are active and blocks 8080.

Lars

Are you sure that Tomcat actually shut down ?

Be sure Tomcat is dead by invoking ps -ef | grep tomcat and killing any
processes(es) which may be running, and then start it again. If you get that
memory leak error again, then something else is not right.

Having said that, I agree with Knut. 1GB will really be pushing it, but
you might be able to get it to work.

Jason

Hi David,

1 GB is probably pushing it a bit, AFAIK. Possible, but not too easy....2
GB should be fine.

Hi

I registered for a free tier EC2 instance (t2.micro) on Amazon with
Ubuntu 14.04 AMD64 Compute – Amazon EC2 Instance Types – AWS
I have set it up according to the DHIS2 implementation manual.
I'm aware that this low hardware specifications are not ready for
national use, I'd like to use it as prototyping resource. However, the
server responds to pings but is not accessible through the browser. I
suspect the memory configuration. Please find the relevant configurations /

Hardware:

Thanks all for your suggestions. I got an instance from a simpler VPS service (DigitalOcean) with 2GB/2CPU and it’s running well without any complex configurations needed.

Initially I followed the Implementation Guides' minimal requirements from and suggest adding the mentioned implications to it, may help other implementers, too (or should I add it to myself?) Best David

You could (in server.xml) reduce the max size of tomcat threadpool to maybe 4 or 5. 3. There are some dhis internal threadpool configs you can also reduce but its a bit more fiddly (and I don't have the details at hand) The sensible thing (depending on what you are trying to achieve) is to increase your available RAM to 2G or more. getting it to run in 1G is an interesting challenge which I've achieved once or twice but really not all that useful.

Hi David, INFO: Pausing ProtocolHandler ["http-bio-8080"] you are running on port 8080, this might be related to firewalls on aws. Try running on port 80 (conf/server.xml). Alternatively check if firewalls are active and blocks 8080. regards, Lars On Wed, Sep 2, 2015 at 3:47 PM, Dan Cocos wrote:



At BAO we've found we could only reliably support DHIS 2 with a minimum of 2GB.

Be sure Tomcat is dead by invoking ps -ef | grep tomcat and killing any processes(es) which may be running, and then start it again. If you get that memory leak error again, then something else is not right. Having said that, I agree with Knut. 1GB will really be pushing it, but you might be able to get it to work.

Hi David, 1 GB is probably pushing it a bit, AFAIK. Possible, but not too easy....2 GB should be fine. Knut On Wed, Sep 2, 2015 at 12:11 PM, David Huser wrote:


Hi I registered for a free tier EC2 instance (t2.micro) on Amazon with Ubuntu 14.04 AMD64 I have set it up according to the DHIS2 implementation manual.
