• bin/check-oracle-alive.rb
• bin/check-oracle-query.rb

-- check a single connection
check-oracle-alive.rb -u scott -p tiger -d hr

-- check a single connection with timeout
check-oracle-alive.rb -u scott -p tiger -d hr -T 30

-- check multiple connections as defined in a file, use 5 worker threads (-W 5) and verbose output (-v)
check-oracle-alive.rb -f connections.csv -W 5 -v

> cat connections.csv
  # production connection
  example_connection_1,scott/tiger@hr

  # test connection
  example_connection_2,scott/tiger@hr_test

-- check for invalid objects in a schema, shows type and name if there are invalid objects (-s), define a ciritical boundary only (-c)
check-oracle-query.rb -u scott -p tiger -d hr -t -s -query "select object_type, object_name from user_objects where status = 'INVALID'" -c "value > 0"

-- same as above but check for all connections in a file, use 5 worker threads
check-oracle-query.rb -f connections.csv -t -s -query "select object_type, object_name from user_objects where status = 'INVALID'" -c "value > 0" -W 5
