Move AwareIm to a new server

lineamovil

Hello!

Im going to move AwareIM 5.8 from my server:
From:
MySQL Server,
Windows 2008,
4GB RAM
Core i3 CPU

to a new server:
AwareIM 5.8
MySQL Server
16 GB RAM
1TB HD
XEON procesor

I just want to know if someone has done similar before and maybe give me some tips in how to do it right. (have the least problems possible)

My application has been working fine for over 2 years, but now it is getting slow. Have some BOs with 150,000 records. Maybe around 15 users the the same time.

I assigned 256MB in RAM to Mysql server, and 1024MB RAM to AwareIM

Your comments make this blog great.

Hi,

I have moved my apps to a new server a couple of months ago.
there is a topic on this forum which I have also followed.

Note: You will need support from Vlad to un-register the old server and register the new one(license).

I think this is the topic: https://forum.awareim.com/d/4839/1&hilit=move+server#p18243

If you need more info, let me know.

Nice day,

lineamovil

Thank you George.

Also, how much memory do you have assigned to MySQL sever?

Hi,

My apps are still in development and I do not changed anything on this side, everything is default yet.
But, soon I will do some research/tests to setup these parameters and let you know about the results.

Thx.

What!!!!

Is that possible with AwareIm 5.8? I thought that it was only possible 1024, 512, 256
I have only 256MB for MySQL

I will try the same configuration for 5.8
Best regards...

Rennur,

When you installed the Mysql sever, how did you manage to assign that memory? Selection Dedicated server? or any tweaking in the My.cnf?

I really dont mess with memory, but will love to know you did that. I also have 16GB RAM in the new server.

Thanks!

I did not assign specific system memory (RAM) to MySql, Windows itself manages that separate of Aware IM.
How MySQL Uses Memory.

Assign as much memory as possible to Aware IM via the server settings. It doesn'tmean Aware requires or will use that much but the more memory it has to work with the better.

Are your system Aware IM components (JDK, Tomcat or MySQL) 64bit?

Rennur

Notice the memory resources used by my Aware IM server (my app is med->big in size with about 15 heavy and 30 light users):

Javaw.exe 2600mb+ RAM is the Server, the other 2 are Tomcat and Config Tool.
If I had the server set up as 1024MB RAM it wouldn't run or would have issues.

Rennur,
Just curious. If the MAX memory available for Java 64 is 4GB, why do you have a lot more than that? Is it possible i.e. does it work to assign more memory?

Thanks

Hi!

We, I have the standar Tomcat and Java that comes with AwareIm.

I havent changed anything about it. I will look in the blog, but if you have some info, it is greatly appreciated.

Thank you!

I have never heard of 4GB being max memory for a JVM 64, i think you must be confusing this with max memory of win 32 environment ? I have seen some configurations of JVM 64 at 6 GB

This has been discussed at length in the forum and I might be (and hope I am) mistaken. My impression from previous discussions is this:

If you use Java32 with Aware IM you can MAX allocate 2GB.
If you use Java64 with Aware IM you can MAX allocate 4GB.

If it´s possible to use more than 4GB (Java64) then that´s very welcome news and new to me. Is there a Java expert or if support could comment, is this correct?

Thanks

According to this FAQ it's only limited by memory and swap space on the local system:

On 64-bit VMs, you have 64 bits of addressability to work with resulting in a maximum Java heap size limited only by the amount of physical memory and swap space your system provides.
See also Why can't I get a larger heap with the 32-bit JVM?

Also keep in mind you need to set the max heap via command line. Without an -Xmx command. without it Java uses 64mb + 30% = 83.2mb as a default max heap on 64 bit machines according the same FAQ.

java -Xmx1000g myClass

Very nice and good news then 🙂.

Support, a tip is to write something about this (Java 32 VS 64 and memory usage etc. etc.) in the userguide or howto document because this is important and not apparent information.

Hello Rennur!

I have visited your great webiste: https://github.com/RennurApps/AwareIM-resources and really helpful, but I just find out that Java64 and Tomcat 8 work only for AwareIm 6 and above. I have AwareIm 5.8.

Im trying to make the most out of it, but it only allows me to place 1024MB for AwareIM server and 1024 for tomcat. Is there any way that I can double this settings? I have 16GB RAM.

Best regards,

Rennur

Not aware of any limitations to allocating more than 1024. I was able to do so in 5.8 i think.
Do you get an error message when you allocate more than 1024?

JDK 8 is fine for Tomcat 6, no issues there. You first must install JDK 8 on your system (download and run installer)

lineamovil

I made all the steps in here https://github.com/RennurApps/AwareIM-resources but I get this error:

"Could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg"

I have AwareIM 5.8 I also tryed installing another version of JAva. Im using this one right now.
Windows x86 175.98 MB jdk-8u45-windows-i586.exe
Windows x64 180.44 MB jdk-8u45-windows-x64.exe

In tomcat: version 8 64-bit Windows zip (pgp, md5, sha1)

Any suggestions?

I have been running 64 bit with high memory allocation on very old versions of AIM, so i don't believe there is any limitations
Have you done this: After a clean install of AIM do the following

1.After installing the latest JVM on your machine you need to copy and paste the JDK from the C:\Program Files\Java\ ...into your AIM directory , rename the existing JDK to JDK 32

Then copy the tools.jar file from C:\Program Files\Java... to the AwareIM\ tomcat\lib\
Also manually set the memory setting on the AwareIM\Bin\startAwareIM.bat file
Load AIM and check for 64 bit functionality (on a 64 bit windows machine you will note in the task manager the jvm process does not have a (32) in the process description.

This should get you to full 64 bit functionality

Proceed with the rest of the updates as per rennur recommendation

GREAT!

It works fine!

I was also updating the Tomcat. Maybe thats where the problem was. Thank you so much!

Great help all of you!!
