-The database should be created in the appropriate project compartment at the DB layer, using the DB subnet and assign the NSGs to the database.

-Example for Prod database: 
-
-* **Compartment**-> cmp-landingzone-p:cmp-lzp-prod:cmp-lzp-p-projects:cmp-lzp-p-proj1:cmp-lzp-p-proj1-db
-* **Network**-> vnc:vcn-fra-lzp-p-projects; subnet:ssn-fra-lzp-p-db

-If the database was created previously, ensure it is placed in the correct CMP, assigned to the proper subnet, and configured with the appropriate NSG.

-Create the OPSI private endpoint. 
-
-* In a **global approach**, OPSI PEs will be placed in the monitoring subnet (sn-fra-lzp-hub-mon) in the hub and should be assigned to the PE NSGs (nsg-fra-lzp-hub-global-mon-pe). Example: pe_lz_global_opsi.
