Hello, dear!
This is a solution to fail to log in to the OMU portal.
Problem Description
When I log in to the OMU portal, the system prompt that "Login failed. The possible cause is that the connection to the OMU fails."
Solution
Check the database.
ps -ef|grep postgres
The normal output is as shown below:

If it is determined that the database is not started., enter following command:
/home/ivstool/bin/service.sh stop pgdb
mv /DB_DATA/data/global/pg_dataxlogchk /DB_DATA/data/global/pg_dataxlogchk_back
/home/ivstool/bin/service.sh start pgdb
Best wishes!
