[anikettstiwari]

I am trying to upgrade the rails version from 5.1.4 to 5.2.6

When I have remove self.cache_columns = true line from the oracle.rb file. As per the Documentation I ran rails db:schema:cache:dump and it generated a file for me db/schema_cache.yml.

My oracle.rb

ActiveSupport.on_load(:active_record) do
  ActiveRecord::ConnectionAdapters::OracleEnhancedAdapter.class_eval do
    # true and false will be stored as 'Y' and 'N'
    #self.emulate_booleans_from_strings = true

    # start primary key sequences from 1 (and not 10000) and take just one next value in each session
    #self.default_sequence_start_value = "1 NOCACHE INCREMENT BY 1"

    # Use old visitor for Oracle 12c database
    self.use_old_oracle_visitor = true
  end
end

Now when I try to run rspec spec/ it shows me to run rails db:migrate RAILS_ENV=test

And when I run rails db:migrate RAILS_ENV=test It gives me the following error.

Note: My specs were earlier running but while upgrading it is failing. Also, when i see the below error it is trying to run the first migration not sure why
