Unable to deploy server configuration using server configuration tool while setting up IBM Mobilefirst 7.1

Question

I am trying to setup IBM Mobilefirst v7.1 on Ubantu 14.04. I have java version "1.8.0_131" trying to configure it with tomcat7.
Application Center is working fine.

when I am trying to deploy server configuration using server configuration tool I am getting an error log is as follows.

Buildfile: /root/.mobilefirst_platform_server/server-configuration-tool/Configuration_SALESDEMO/SALESDEMO.xml

adminstall:

Thank you in advance.

Answer 1

The problem was with Tomcat base dir(/var/lib/tomcat7) which doesn't have bin dir and worklight was searching for that. once we repaired tomcat7 installation it worked.

thanks for the support.

Answer 2

From the logs, I see that the install job is failing at getBackupFileNextId.

getBackupFileNextId generates a backup file before attempting to alter an application server configuration file.

In a normal scenario, a backup file is created in the conf directory of tomcat.

• Check if you have write permissions to the conf folder

• Please try to deploy MFP through the ANT tasks, below links has more details on the same -
