Observation of very long startup

[Thomas]

Hi,
I made a test install of the new wcs4 (version 4.0.1082).
After starting webcallserver daemon the new wcs-manager is starting but it took more than 50 minutes that it started the actual wcs server. Actually there was not much process activity within those 50 mins.
Additiionally I observed quite a lot of errors during the initialisation of the database.
Attached is a snapshot of the manager log file.
Nevertheless, after that first tests seem to be successful.
BR, Thomas

Thomas,
Thanks for the observation.

First of all try to uninstall any previous WCS4 version if it was installed.
Then install the new version from scratch.

50 minutes is too long time. And it looks like an error.
In our tests the running process takes about 50-60 seconds on VPS server or about 30 seconds on dedicated quad core server.

Some questions related to your system:

1. What is your OS version?

uname -a

2. What is your java version?

java -version

2. What is your hardware (VPS, Amazon instance, etc) ?

Regards,
Max

Actually, I had already once uninstalled and reinstalled - very similar result.

We tested it with own hardware servers Core i7, Xeon E5410. We also tested it with didgitalocean cloud servers, i.e. Xeon E5-2630L. And it worked well. Only difference I see is the CPU. In our tests we used Intel CPU. Your testing platform is based on AMD Opteron. Try to install WCS to another server: hardware server, Amazon EC2 or digitalocean cloud server.

Another option, please provide access to your testing server and we will try to check it.
Send email to logs@flashphoner.com with access details.

WCS4 requires a lot of CPU resources on startup because it is deploying internal services while starting (REST, Database, Web container, Internal component scans, etc). Maybe your server-instance is too slow in CPU terms.

Max

Hi Max,
I installed it meanwhile on Amazon EC2 successfully. Seems that you are right with the assumption concerning AMD Opteron.
Is there some Java stack incompatibility? I remember from colleague that a test WCS3 worked on a similarv platform (same IAAS provider) quite smoothly.
BR, Thomas

Thomas,
WCS3 is a lightweight box comparing with WCS4.
WCS4 has a set of integration and management add-ons such as embedded web-server for REST API, interactive command line interface (CLI) working over SSH, built-in database for applications etc. Some of these add-ons can use particular CPU instructions or hardware accelerations (for example for encryption, SSH, AES). It seems AMD platform does not support such capabilities. Currently we do not have a lot of request regarding AMD, so we suggest to use Intel platform. However if AMD deployment is critical requirement, please contact our support or sales team. We will try to find a solution.
