Knowledge Base

How do I resolve the 'skipping appserver start - HA passive' error on Linux?

Symptoms

On a Linux machine, using High Availability mode on the primary Controller or the single Controller on which service scripts are installed in non-High Availability mode, the command service appdcontroller start does not start the App Server. 

 

Error message:

Skipping appserver start - HA passive 
Watchdog disabled

 

Diagnosis

The MySQL database root user password is not obfuscated and stored.

Solution

In the computer terminal use the following commands to prompt for the MySQL root password.

 

cd <controller_home>/HA
./save_mysql_passwd.sh

Enter the root password, then try the service appdcontroller start command again.

 

If unsure of the root password, enter the command <controller_home>/bin/controller.sh login-db and then enter the root password. If the password allows you to log in, it is correct.



Stop services:

 

service appdcontroller stop
service appdcontroller-db stop

 

Start services:

 

service appdcontroller start
