+# IFS Deployment Steps Guide
+
+This guide details the steps for installing a new delivery package in IFS, covering environment setup, database preparation, installation, and final cleanup.
+
+-----
+
+### **I. Preparation and Access**
+
+1.  **Log in to VPN:**
+      * Log in to the **IPL - VPN**.
+2.  **Log in to Management Server:**
+      * Log in to the **Management Server** (e.g., `ifsapp`).
+3.  **Check Current Delivery Level:**
+      * Check the current delivery level from the application, specifically using the **Delivery Registry**.
+4.  **Identify Target Delivery:**
+      * The delivery you need to install is the **next available delivery**.
+5.  **Download Delivery Package:**
+      * **Download the delivery** from the **build place**.
+6.  **Copy Delivery Package:**
+      * **Copy the delivery package** to the designated **delivery installation directory**.
+
+-----
+
+### **II. Environment Configuration (Kube & Middle-Tier)**
+
+7.  **Source the Environment with Kube Configuration:**
+      * Run the following commands to configure `kube`:
+        ```bash
+        .\main.ps1 -resource 'GETKUBECONFIG'
+        copy .\config\kube\config $HOME\.kube\
+        ```
+8.  **Verify Namespace and Pods:**
+      * The correct namespace is **"IPLUPG"**.
+      * Get all namespaces:
+        ```bash
+        kubectl.exe get ns
+        ```
+      * Verify running Pods in the target namespace:
+        ```bash
+        kubectl.exe get pods -n IPLUPG
+        ```
+9.  **Stop the Middle-Tier:**
+      * Stop the Middle-Tier. The namespace is **"IPLUPG"**.
+      * **Command Example:**
+        ```bash
+        <path to delivery installation folder>\mtctl.cmd stop -n IPLUPG
+        ```
+
+-----
+
+### **III. Database Preparation**
+
+10. **Log in to Oracle Server:**
+      * Log in to the **Oracle Linux server** with the username **"oracle"**.
+      * Connect to the database:
+        ```bash
+        sqlplus / as sysdba
+        ```
+11. **Source the Instance:**
+      * Set the Oracle environment ID:
+        ```bash
+        . oraenv
+        # OR
+        set oracle_sid=<SID>
+        ```
+12. **Verify Instance and PDB Status:**
+      * Check the status of Pluggable Databases (PDBs):
+        ```sql
+        show PDB
+        ```
+13. **Check Archive Log Mode:**
+      * Determine if the DB is running in `archive log` or `no archive log` mode:
+        ```sql
+        archive log list
+        ```
+14. **Check DB Recovery Destination:**
+      * Check the recovery file destination and size parameters:
+        ```sql
+        show parameter db_recovery_file_dest_size
+        show parameter db_recovery_file_dest
+        ```
+15. **Create Temporary Directory:**
+      * Create a directory named **"TEST"** in the `/u02` partition:
+        ```bash
+        mkdir /u02/TEST
+        ```
+16. **Configure Recovery Destination (If No Archive Log):**
+      * If the database is in `no archive log` mode, configure the destination:
+        ```sql
+        db_recovery_file_dest_size=100G
+        db_recovery_file_dest=/u02/TEST
+        ```
+17. **Set Database to Archive Log Mode:**
+      * **Change DB to Archivelog:**
+        ```sql
+        shutdown immediate
+        startup mount
+        alter database archivelog;
+        alter database open;
+        ```
+      * *(The "No Archivelog" commands are provided here for later reference.)*
+          * *Change DB to No Archivelog:*
+        ```sql
+        *shutdown immediate*
+        *startup mount*
+        *alter database noarchivelog;*
+        *alter database open;*
+        ```
+18. **Verify Instance and PDB Status (Post-change):**
+      * Re-verify the status of PDBs:
+        ```sql
+        show PDB
+        ```
+19. **Configure Restore Point:**
+      * Create a guaranteed restore point before deployment:
+        ```sql
+        create restore point delivery guarantee flashback database;
+        ```
+      * *(To drop the restore point later, use:* `drop restore point delivery;`*)*
+

+
+### **IV. Delivery Installation and Verification**
+
+20. **Run the Delivery Database Part:**
+      * Execute the database installer part of the delivery:
+        ```bash
+        .\installer.cmd --set action=dbinstaller --values <Path>\ifscloud-values.yaml --values <Path>\solutionset.yaml --set dbInstaller.sysPassword=<DBPassword>
+        ```
+21. **Verify the Logs:**
+      * Check for errors and successful completion in the logs located at:
+        ```bash
+        ifsroot\logs\ifscloudinstaller\
+        ```
+22. **Run the Delivery Middle-Tier Part:**
+      * Execute the middle-tier installer part:
+        ```bash
+        .\installer.cmd --set action=mtinstaller --values <Path>\ifscloud-values.yaml
+        ```
+23. **Verify the PODs Status:**
+      * Check the status of the pods to ensure the middle-tier has started successfully:
+        ```bash
+        kubectl.exe get pods -n IPLUPG
+        ```
+24. **Login and Verify Delivery Level:**
+      * **Log in to the application** and verify that the new **delivery level** is correctly displayed.
+
+-----
+
+### **V. Post-Installation Cleanup**
+
+25. **Drop Restore Point (If Successful):**
+      * If the delivery is successful, remove the restore point:
+        ```sql
+        drop restore point delivery;
+        ```
+26. **Stop Application:**
+      * Stop the application (if necessary).
+27. **Change Database to No Archivelog:**
+      * Revert the database to **No Archivelog** mode:
+        ```sql
+        shutdown immediate
+        startup mount
+        alter database noarchivelog;
+        alter database open;
+        ```
+28. **Start Application:**
+      * Start the application to bring the system online.
