Minhaas · 8 July 2019 17:43

These are the warnings I am getting when I shutdown tomcat, I am on tomcat7, PostgreSQL 9.5, PostGIS -2.2, DHIS 2.3.1, localist:8080/Root also shows that it doesn’t exist. Please help.

This is the installation methodology I used

Hi @Minhaas,

at first glance I see two things:

You are using Postgres 9.5, the minimum version now is 9.6. But this is not your immediate problem it seems.
Your logs complain about not having access to directories. This is an indication that your read and write permission for these folders is not correct. Make sure the user running tomcat has correct access to these directories.

Thank you so much for the assistance, the deeper problem was associated with

Postgres 9.5
Out of shared memory error, both of which were solved with the help of other community posts.

dhis2 works like a charm.

For thr second error, I had to navigate to the postgres.conf file and change max_locks_per_transaction to 1024, this made my PostgreSQL work.
