MODIFYING VSPHERE WEB CLIENT AND HTML5 CLIENT SESSION TIMEOUT –

VCSA 6.X

Posted on January 11, 2019

by RHari

vSphere and HTML clients comes with a 120 minutes timeout. For our Non-PROD infra we decided to set it to 24 hrs which is 1440 in

minutes.

below are the steps

1) SSH to VCSA

If SSH is not enabled, you may do it from Appliance Management Page Access it at VCSA-IP:5480 3) Below are the config file locations for vSphere 6.5 and 6.7 Web Client – /ETC/VMWARE/VSPHERE-CLIENT/ HTML5 Client – /ETC/VMWARE/VSPHERE-UI/ 4) Config file name is “_webclient.properties_“. You need to open this file and look for “_session.timeout_” and change  value to your desired time out value in minuted. For me it’s 1440, which is 24 Hrs like I mentioned. _vi /etc/vmware/vsphere-client/webclient.properties_ Do the same for  HTML5 client at _vi /etc/vmware/vsphere-ui/webclient.properties_ 5) Now it’s time to restart services for the change to take affect. service-control –stop vspherewebclientsvc service-control –stop vsphere-client service-control –start vspherewebclientsvc service-control –start vsphere-client

Done!

VCSA 6.0 TO 6.5 UPGRADE FAIL – MIGRATION ASSISTANT ON VUM SERVER Posted on June 20, 2018

by RHari

Upgrading PSC 6.0 appliance to 6.5 worked like a charm. Next step was vCenter appliance upgrade,which would now consolidate Windows based VUM server to the vCenter appliance. So this requires you to run VMware Migration Assistant on the Windows VUM server. Every time I start the Migration Assistant it failed with an below

error

ERROR: A PROBLEM OCCURRED DURING AUTHENTICATION TO THE LEGACY VCENTER SERVER USING THE PROVIDED CREDENTIALS. RESOLUTION MAKE SURE THE VCENTER SERVER IS UP AND RUNNING. VERIFY YOU HAVE ENTERED THE CORRECT

CREDENTIALS.

I was sure that the SSO password is correct.
