Tomcat 503 Service Unavailable

  

Hello everybody, I want to set up an IIS in front of my engine. I already executed the batch script as in the integration-guide described. Now if I want to access the engine I get the following message: 'Service Temporarily Unavailable! Tomcat - Service Unavailable I am running GW 7.0.2 with all agents on one server, Netware 6.5 sp7. Prior to updating the server to sp7 GW webaccess/java would crash after about 1.5 months, when the server began getting Cache memory errors.

  1. 503(Relatively rare) Definition. 503 service unavailable: indicates that the server is currently in a temporary unavailable state. Whether intentionally or unintentionally, the status code will be returned when the server is in a state that cannot be answered. Among them, it is intentional for the server to stop service due to maintenance needs.
  2. Try to use httpComponents instead of tomcat for the receiver. HttpComponents is better for high concurrency, but its less performant compared to tomcat for lower concurrency. But it may still be in your limits, its just relative observation. I am not sure if you are getting few 503 errors or all of them are getting errored out.

For more information about other potential causes and symptoms, see “503 Service unavailing “error on the vSphere Web Client when logging in or logging the vCenter Server.
The Purpose
when one or more services or endpoints are unavailable, an HTTP 503 error response code may be returned. For example, the vCenter Server service might not be running or Stopped while the vSphere Web Client service is running.
Resolution
to troubleshoot this problem:

    verify that the computer trying to access the vCenter Server using the vSphere Web Client with Telnet is connected by running the following command:
telnet vcenter_fqdn 9443
    runs the following command to check whether the partition on the VCSA has enough free space:
Df-h
* in version 6.7, the /storage/archive partition should be full, which is expected behavior. For details, see “File System /storage/ Archive is low on Storage Space “on the VCSA 6.7 VAMI Page
    use the following command to ensure that the vCenter Server service is running:

Service – control – the status – all
* If any of the services shut down unexpectedly, you can start all of them by running the following command:
Service – control – start – all
* If the PSC is external, you may also need to check the services on the PSC.
For more information on how to stop/start the service, see the following articles:
How to Stop, Start or Restart vCenter Server 6.x Services
Stopping, Starting or Restarting VMware vCenter Server Appliance 6.x services

    to ensure that VCSA has enough resources to handle requests, you may need to use the top command to check CPU/ memory usage on both the host and the VCSA. If all VC services are up and the Web Client is still not open, you can find more details on this issue in the virgo log at the following location:
