Issue/Introduction

Got following message during the CA PC upgrade from 3.7.5 to 3.7.9

Invalid Database Password (root)

--------------------------------

The provided database password is invalid for the root user, please try again.

I stopped mysql process before the upgrade. Please advice what action need to take to correct this issue.

Environment

CAPM 3.x

Cause

mysql was down

Resolution

Make sure mysql is running when you run the upgrade

For RHEL 7:

systemctl stop mysql 
systemctl start mysql 
systemctl status mysql 


Foe RHEL 6:

/etc/init.d/mysql stop 
/etc/init.d/mysql start 
/etc/init.d/mysql status 

Mysql needs to be running for the upgrade to run and complete successfully
