+
+## Security updates, alerts and bulletins
+
+Security updates will be released on a regular cadence. Many of our projects
+will typically release security fixes in conjunction with the
+[Oracle Critical Patch Update][3] program. Additional
+information, including past advisories, is available on our [security alerts][4]
+page.
+
+## Security-related information
+
+We will provide security related information such as a threat model, considerations

+# Enable automatic data optimization
+
+## Introduction
+
+The massive growth in data volume experienced by enterprises introduces significant challenges. Companies must quickly adapt to the changing business landscape without influencing the bottom line. IT managers need to manage their existing infrastructure to control costs efficiently yet deliver extraordinary application performance. Advanced Compression and Oracle Database together provide a robust set of compression, performance, and data storage optimization capabilities that enable IT managers to succeed in this complex environment. Using Advanced Compression, enterprises can efficiently manage their increasing data requirements throughout all components of their data center – minimizing CapEx and OpEx costs while continuing to achieve the highest levels of application performance.
+
+Estimated Time: 20 minutes
+
+### About automatic data optimization
+
+Automatic data optimization allows organizations to create policies that implement data compression and storage tiering automatically. ADO policies define conditions and corresponding actions to be applied to specific objects. Utilizing the information maintained by Heat Map, Oracle Database executes the registered ADO actions, for the requested objects, to move them to the desired state transparently and automatically.
+
+### Key Features 
+
+Exponential data growth has put severe pressure from a cost, performance, scalability and management perspective. It has become imperative to employ more efficient ways of storing and managing data to meet the growing demands on IT systems. The rapid growth in data volumes and associated costs are of significant concern for many companies. The companies have started a global initiative to identify and drive a reduction in storage costs. 
+
+*	ADO policies can be specified at the segment level or the row level for tables and partitions. 
+*	Segment and row-level ADO policies are evaluated and executed automatically in the background during maintenance windows or executed on demand. 
+*	Storage tiering is specified at the segment level and triggered by space pressure in the tablespace where the segment resides. 
+
+This Lab will teach you how to enable Automatic Data Optimization. 
+
+### Objectives
+
+In this lab, you will:
+* Enable automatic data optimization
+
+### Prerequisites 
+This lab assumes you have:
+
+* A LiveLabs Cloud account and assigned compartment
+* The IP address and instance name for your DB19c Compute instance
+* Successfully logged into your LiveLabs account
+* A Valid SSH Key Pair
+
+## Task 1: Enable automatic data optimization
+
+1.  Create table students 
+
+    ```
+    <copy>
+    CREATE TABLE students (
+        student_id NUMBER , first_name VARCHAR2(128) , last_name VARCHAR2(128) 
+        ); 
+    </copy>
+    ```  
+
+2.  A segment-level ADO policy is created to automatically compress the entire table after there have been no modifications for at least 30 days, using Advanced Row Compression.
+
+    ```
+    <copy> 
+    ALTER TABLE students ILM ADD POLICY ROW STORE COMPRESS ADVANCED SEGMENT AFTER 30 DAYS OF NO MODIFICATION;
+    </copy>
+    ```
+
+3. A row-level ADO policy is created to automatically compress blocks in the table, after no rows in the block have been modified for at least 3 days, using Advanced Row Compression..
+
+    ```
+    <copy>
+    ALTER TABLE students ILM ADD POLICY ROW STORE COMPRESS ADVANCED ROW AFTER 3 DAYS OF NO MODIFICATION;
+    </copy>
+    ```
+
+4. View user\_ilmpolicies table    
+
+    ```
+    <copy>
+    select * from user_ilmpolicies;
+    </copy>
+    ```
+
+    ![User ILM Policies](images/user-ilmpolicies.png "User ILM Policies")
+
+ 
+## Task 2: Cleanup
+
+1. When you are finished testing the example, you can clean up the environment by dropping the tables
+ 
+    ```
+    <copy>
+    drop table students purge; 
+    </copy>
+    ```
+  
+    You successfully made it to the end of this lab.

+# Enable advanced index compression 
+
+## Introduction
+
+Indexes are used extensively inside OLTP databases since they can efficiently support a wide variety of access paths to the data stored in relational tables. It is prevalent to find many indexes created on a single table to support many access paths for OLTP applications. This can cause indexes to contribute a more significant share to the overall storage of a database when compared to the size of the base tables alone. Advanced Index Compression is a form of index block compression. Creating an index using Advanced Index Compression reduces the size of all supported unique and non-unique indexes while still providing efficient access to the indexes. 
+
+Estimated Time: 20 minutes
+
+### About Advanced index compression
+
+Advanced index compression LOW works well on all supported indexes, including those indexes that are not good candidates (indexes with no duplicate values or few duplicate values for a given number of leading columns of the index) with the existing Prefix Compression feature. Advanced Index Compression HIGH works at the block level to provide the best compression for each block. This means that users do not need knowledge of data characteristics – Advanced Index Compression HIGH automatically chooses the right compression per block.The HIGH level of Advanced Index Compression provides significant space savings while also improving performance for queries that are executed using indexes. Advanced Index Compression LOW and HIGH both provide significant space savings while also improving performance for queries that are executed using indexes.
+
+### Key Features
+
+* Gives higher compression ratios.
+* Employs more complex compression algorithms than advanced index compression LOW.
+* Stores data in a compression unit, which is a special on-disk format.
+
+### Expectations from adapting a compression technique 
+
+*	Storage costs to drop as the result of any compression deployments, and 
+*	No query performance degradation and only minimal Data Manipulation Language (DML) performance impact from compression.
+
+This Lab will teach you how to enable advanced index compression. 
+
+### Objectives
+
+In this lab, you will:
+* Enable Advanced Index Compression
