Following instructions are for stopping:

• Autonomous Databases
• Compute VMs
• DBCS VMs
• OAC native

Step 1: Install and configure OCI CLI on a Compute Intance (Linux VM with one CPU would be ok) in your tenancy. https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliinstall.htm It takes about 10min

This version uses Instance Principals for Authenticaion: create a Dynamic Group and add a rule for the OCID of the compute instance where the scripts will run create a policy in the root compartment as follows: Allow dynamic-group <group_name> to use all-resources in tenancy

Step 2: Save the delivered shell scripts on the VM, e.g. in /home/opc/ocicli/autostopping/ Create a sub-directory named log: i.e. /home/opc/ocicli/autostopping/log/

Step 3: Change the WHITELIST_FILE path in the .sh scripts accordingly. See Step 7. e.g.: WHITELIST_FILE="/home/opc/ocicli/autostopping/whitelist.txt"

Step 4: Make the shell scripts executable chmod +x /home/opc/ocicli/autostopping/*.sh

Step 5: As we are using Instance Principals for Authentication, there is no config file contaning the Tenancy ID: Change the value of TENANCY_OCID to your tenancy ID in all scripts

Step 6: Create an automation using corntab. In the following example shutting down the resources every day at 6p.m. and keeping the log files for 7 days. 0 18 * * * /home/opc/ocicli/autostopping/stop_adbs.sh > /home/opc/ocicli/autostopping/log/stop_adbs_date '+\%Y\%m\%d_\%H\%M\%S'.log 0 18 * * * /home/opc/ocicli/autostopping/stop_dbsystem_nodes.sh > /home/opc/ocicli/autostopping/log/stop_dbsystem_nodes_date '+\%Y\%m\%d_\%H\%M\%S'.log 0 18 * * * /home/opc/ocicli/autostopping/stop_computes.sh > /home/opc/ocicli/autostopping/log/stop_computes_date '+\%Y\%m\%d_\%H\%M\%S'.log 0 18 * * * /home/opc/ocicli/autostopping/stop_oac.sh > /home/opc/ocicli/autostopping/log/stop_oac_date '+\%Y\%m\%d_\%H\%M\%S'.log 0 3 * * * find /home/opc/ocicli/autostopping/log/ -type f -mtime +7 -name '*.log' -execdir rm -- '{}' ;

make sure your environment is sourced in cron by add following line to crontab (change the path to your .profile file): SHELL=/bin/bash BASH_ENV=/home/opc/.bash_profile

IMPORTANT: the scripts do not start the resources in the next morning: Option 1: every one in the team starts only the resources needed manually. Option 2: duplicate the scripts and replace "stop" by "start" and create crontab roles to run them

Step 7: If you are using a compute VM in OCI to run the scripts, don't forget to tag this instance with a TAG named "AutoStopping" and value "NO" to prevent the scripts from stopping the instance where they are running ;-)

Step 8 (Optional): To prevent specific instances from auto stop, add a TAG named "AutoStopping" with the value "NO" to the resource

Step 9 (Optional): To prevent all ADBs, Compute, and DB Systems of a specific Compartment to be stopped, add the TAG to the Compartment itself. Some Compartments like ManagedCompartmentForPaaS cannot be edited. In this case add the Compartment OCID ot the whitelist.txt file.
