+
+
+Oracle Database In-Memory (Database In-Memory) is a product, first introduced in Oracle Database 12c, that improves the performance of analytic queries by orders of magnitude. It makes it possible to enable real-time analytics in mixed workload environments. Since it is fully integrated into Oracle Database and requires no application changes to use, it can be used in any Oracle Database environment where existing reporting or analytic workloads exist to provide orders of magnitude performance improvements.
+
+The In-Memory Column Store (IM column store) is a key feature of Database In-Memory. The In-Memory Column Store (IM column store) stores tables and partitions in memory using a columnar format optimized for rapid scans. Oracle Database uses a sophisticated architecture to manage data in columnar and row formats simultaneously. This lab will explore how Database In-Memory works and the newer features that have been added in Oracle Database 19c and 21c.

+# Initialize Environment
+
+## Introduction
+
+In this lab we will review and startup all components required to successfully run this workshop.
+
+*Estimated Lab Time:* 15 Minutes.
+
+### Video Preview
+Watch the video below to get an explanation of enabling the In-Memory column store.
+
+[Youtube video](youtube:dZ9cnIL6KKw)
+
+Watch the video below for a walk through of the lab.
+[Youtube video](youtube:7rbgF8Z6hc4)
+
+
+### Objectives
+- Initialize the workshop environment.
+
+### Prerequisites
+This lab assumes you have:
+- A Free Tier, Paid or LiveLabs Oracle Cloud account
+- You have completed:
+    - Lab: Prepare Setup (*Free-tier* and *Paid Tenants* only)
+    - Lab: Environment Setup
+
+**NOTE:** *When doing Copy/Paste using the convenient* **Copy** *function used throughout the guide, you must hit the* **ENTER** *key after pasting. Otherwise the last line will remain in the buffer until you hit* **ENTER!**
+
+## Task 1: Validate That Required Processes are Up and Running.
+
+1. Now with access to your remote desktop session, proceed as indicated below to validate your environment before you start executing the subsequent labs. The following Processes should be up and running:
+
+    - Database Listeners
+        - LISTENER (1521)
+        - LISTCDB2 (1522)
+    - Database Server Instances
+        - CDB1
+        - CDB2
+
+    ![In-Memory landing page](./images/remote-desktop-landing.png " ")
+
+2. Click the *Terminal* icon on the desktop to launch a session, then run the following to validate that expected processes are up.
+
+    ```
+    <copy>
+    ps -ef|grep LIST|grep -v grep
+    ps -ef|grep ora_|grep pmon|grep -v grep
+    systemctl status oracle-database oracle-db-listener
+    </copy>
+    ```
+
+    ![Check PMON Database process status](./images/check-pmon-up.png "check PMON Database process status")
+    ![Check database service status](./images/check-db-service-up.png "Check database service status")
+    ![Check DB listener service status](./images/check-dblistner-service-up.png "Check DB listener service status")
+
+    If all expected processes are shown in your output as seen above, then your environment is ready for the next task.  
+
+3. If you see questionable output(s), failure or down component(s), refer to the appendix section to restart the service accordingly
+
+4. Follow the (3) steps shown below to launch *SQL Developer*:
+
+    ![Launch SQL Developer](./images/launch-sqldeveloper.png "Launch SQL Developer")
+
+5. Test database connectivity by clicking on the *+* sign next to each CDB or PDB listed as shown below
+
+    ![Test Database Connections](./images/test-database-connections.png "Test Database Connections")
+
+
+## Task 2: Initialize Database for In-Memory Use Cases
+
+1. From your remote desktop session as user *oracle*, run the block below
+
+    ```
+    <copy>
+    clear
+    cd ~oracle/labs
+    rm -rf ~oracle/labs/*
+    wget -O novnc-inmemory-21c.zip https://c4u04.objectstorage.us-ashburn-1.oci.customer-oci.com/p/EcTjWk2IuZPZeNnD_fYMcgUhdNDIDA6rt9gaFj_WZMiL7VvxPBNMY60837hu5hga/n/c4u04/b/livelabsfiles/o/labfiles/novnc-inmemory-21c.zip
+    unzip -qo novnc-inmemory-21c.zip
+    rm -f novnc-inmemory-21c.zip
+    cd inmemory
+    ls -ltrh
+    </copy>
+    ```
+
+    ![query image](./images/init-inmemory.png " ")
+
+2. This workshop will use CDB1 exclusively. As a result, run the following to disable *CDB2* from auto-startup and shut it down.
+
+    ```
+    <copy>
+    sudo systemctl stop oracle-database
+    sudo sed -i -e 's|CDB2.*$|CDB2:/opt/oracle/product/21c/dbhome_1:N|g' /etc/oratab 
+    sudo systemctl start oracle-database
+    </copy>
+    ```
+
+3. Confirm that only **CDB1** database is running on the host.
+
+    ```
+    <copy>
+    ps -ef|grep ora_|grep pmon|grep -v grep
+    </copy>
+    ```
+
+## Task 3: Enable In-Memory
+
+1.  Set your oracle environment and connect to **CDB1** database using SQLcl.
+
+    Run the commands below
+
+    ```
+    <copy>. ~/.set-env-db.sh CDB1</copy>
+    ```
+
+    ```
+    <copy>
+    sql / as sysdba
+    </copy>
+    ```
+
+    Output:
+    ```
+    [CDB1:oracle@dbhol:~]$ . ~/.set-env-db.sh CDB1
