+# C3 Hosting Service Provider - IAM Policies for Isolation
+
+The Hosting Service Provider (HSP) model on Compute Cloud@Customer (C3) allows
+hosting for multiple end customers, each isolated in a dedicated compartment
+with separate VCN(s) per customer. To ensure the end customer can only
+create resources in just their own compartment, a set of IAM policies are
+required.
+
+The HSP documentation suggests the following policies per end customer
+based on an example with two hosting customers, A & B. They assume that
+each end customer will have two roles for their
+staff: Customer Administrator and Customer End User. 
+
+## Example Policies for Customer Administrator
+```
+Allows the group specified to use all C3 services in the compartment
+listed:
+
+Allow group CustA-Admin-grp to manage all-resources in compartment
+path:to:CustA
+
+Allow group CustB-Admin-grp to manage all-resources in compartment
+path:to:CustB
+```
+Note that the above policy grants permissions in the CustA and CustB
+compartments of the C3 but **also in the same compartment in the OCI
+tenancy**! To prevent permissions being granted in the OCI tenancy
+append a condition such as:
+
+```Allow group CustA-Admin-grp to manage all-resources in compartment
+path:to:CustA where all {request.region != 'LHR',request.region !=
+'FRA'}
+
+Allow group CustB-Admin-grp to manage all-resources in compartment
+path:to:CustB where all {request.region != 'LHR',request.region !=
+'FRA'}
+```
+In the example above the condition prevents resource creation in London
+and Frankfurt regions. Adjust the list to include all regions the
+tenancy is subscribed to.
+
+The path to the end user compartment must be explicitly stated, using
+the comma format, relative to the compartment where the policy is
+created. 
+
+## Example Policies for Customer End User
+```
+Allow group CustA-Users-grp to manage instance-family in compartment
+path:to:CustA  
+Allow group CustA-Users-grp to use volume-family in compartment
+path:to:CustA  
+Allow group CustA-Users-grp to use virtual-network-family in compartment
+path:to:CustA  
+Allow group CustB-Users-grp to manage instance-family in compartment
+path:to:CustB  
+Allow group CustB-Users-grp to use volume-family in compartment
+path:to:CustB  
+Allow group CustB-Users-grp to use virtual-network-family in compartment
+path:to:CustB
+```
+As above append a condition to limit permissions to the C3 and prevent
+resource creation in OCI regions:
+```
+Allow group CustA-Users-grp to manage instance-family in compartment
+path:to:CustA where all {request.region != 'LHR',request.region !=
+'FRA'}  
+Allow group CustA-Users-grp to use volume-family in compartment
+path:to:CustA where all {request.region != 'LHR',request.region !=
+'FRA'}  
+Allow group CustA-Users-grp to use virtual-network-family in compartment
+path:to:CustA where all {request.region != 'LHR',request.region !=
+'FRA'}  
+Allow group CustB-Users-grp to manage instance-family in compartment
+path:to:CustB where all {request.region != 'LHR',request.region !=
+'FRA'}  
+Allow group CustB-Users-grp to use volume-family in compartment
+path:to:CustB where all {request.region != 'LHR',request.region !=
+'FRA'}  
+Allow group CustB-Users-grp to use virtual-network-family in compartment
+path:to:CustB where all {request.region != 'LHR',request.region !=
+'FRA'}
+```
+## Common Policy
+
+Currently any user of a C3 needs access to certain resources located at
+the tenancy level to use IaaS resources in the web UI.
+Backup policies, tag namespaces, platform images, all reside at the
+tenancy level and need a further policy to allow normal use of C3 IaaS
+services. Note that this is a subtle difference to the behaviour on OCI. 
+
+An extra policy as below is required (where CommonGroup contains **all**
+HSP users on the C3):
+```
+allow group CommonGroup to read all-resources in tenancy where
+target.compartment.name='root-compartment-name'
+```

+# Lock-Free Reservation
+
+A Lock-Free Reservation allows multiple concurrent updates on a numeric column value to proceed without being blocked by uncommitted updates when adding or subtracting from the column value.
+
+By avoiding the traditional locking mechanism during updates, this feature allows you to greatly improve on the user experience with reduced blocking in the presence of frequent concurrent updates to reservable columns. In previous releases, when a column value of a row is updated by adding or subtracting from it, all other updates to that row are blocked until the transaction is committed. With the introduction of the Lock-Free Reservation feature in Oracle Database 23ai, you can allow transactions 
+to concurrently add or subtract from the same row’s reservable column without blocking each other by specifying the conditions for which the updates may proceed.
+Especially online applications updating intensively and with huge concurrency, low cardinality tables can take advantage of this new feature.
