Would very much appreciate your input on this matter, as our VA environment has been down since friday - has been runnning fine for long ;-(

Public LASR Analytic Server – sasvasmp (RUNNING)

Error: Can't start LASR (public can start)

@GertNissen ,

That message about createClob can be ignored. It feels like the SAS session cannot reach the LASR authorization service. On your compute server create D:\http_logger.xml (I hope you have access to write files to D:\) with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<log4sas:configuration xmlns:log4sas="http://www.sas.com/rnd/Log4SAS/" debug="true">
   <appender class="FileAppender" name="File">
      <param name="File" value="D:\out.log" />
      <param name="Append" value="false" />
      <param name="ImmediateFlush" value="true" />
      <layout>
         <param name="ConversionPattern" value="%d %-5p %c [%t] %X{Client.ID}:%u - %m" />
      </layout>
   </appender>
   <logger name="App.tk.HTTPC">
      <level value="TRACE" />
   </logger>
   <logger name="HTTP">
      <level value="TRACE" />
   </logger>
   <logger name="Perf">
      <level value="Error" />
   </logger>
   <logger name="App">
      <level value="Debug" />
   </logger>
   <logger name="App.Program">
      <level value="Debug" />
   </logger>
   <logger name="Audit.Authentication">
      <level value="Error" />
   </logger>
   <root>
      <level value="error" />
      <appender-ref ref="File" />
   </root>
</log4sas:configuration>

Start the workspace server using a command shown below:

D:\SAS\Config\Lev1\SASApp\WorkspaceServer\WorkspaceServer.sh -logconfigloc D:\http_logger.xml -nodms

Try to start the LASR server and show me SAS log from a console as well as D:\out.log:

libname ml sasiola startserver=( PATH="D:\SAS\Config\Lev1\AppData\SASVisualAnalytics\VisualAnalyticsAdministrator\sigfiles" LOGGING ) host="sasvasmp.XXXX.net" port=10010 signer="http://sasvasmp.XXXX.net:80/SASLASRAuthorization";

Thanks @alexal

Not sure if I'm following your steps correctly?

I don't have write access to 😧 but changed to K: in XML code

Submitted the start Workspace server on CMD (pointing to k:\)

D:\SAS\Config\Lev1\SASApp\WorkspaceServer\WorkspaceServer.bat -logconfigloc K:\http_logger.xml -nodms

Submitted the LASR start code from EG (connected to sasvasmp)

But I dont think I'm hitting the 'new' Workspaceserver ??

No output (or file) in k:\out.log ?

Still struggling with understanding the problem and finding a solution

Found these, perhaps it would help investigation...

Like Public LASR can start, also Env Lasr can start - only 'LASR' that can't start

D:\SAS\Config\Lev1\AppData\SASVisualAnalytics\VisualAnalyticsAdministrator\sigfiles\

ERROR: The LASR Analytic Server image does not contain any tables.

oouupps ;-( sorry

We found the error, and it was actually visible in my first screen shot - well hidden behind the grey overlay.

Somehow we managed to get a third (unknown origin) LASR server using the same port as our existing LASR server.

Not 100% sure where it came from, but bravely (aka desperate) deleted the new unknow LASR server and now our "old" LASR starts again, autoload works again and the users have confirmed everything is working 🙂

That might explain why Public LASR, EnvMan LASR was working, while only LASR LASR was not.
