Azure Expressrout-connect azure network with onpromise

 

Extend an on-premises network using VPN

Bastion
Azure Stack
Virtual Machines
Virtual Network
VPN Gateway

This reference architecture shows how to extend a network from on premises or from Azure Stack into an Azure virtual network, using a site-to-site virtual private network (VPN). Traffic flows between the on-premises network and Azure through an IPSec VPN tunnel or through the Azure Stack multitenant VPN gateway.

Hybrid network spanning on-premises and Azure infrastructures

A diagram of the VPN gateway architecture. An on-premises network connects to an Azure virtual network through a VPN gateway. A virtual network in Azure Stack also connects to the VPN gateway through public VIPs.

Download a Visio file of this architecture.

Reference deployment

This deployment creates two resource groups; the first holds a mock on-premises network, the second a set of hub and spoke networks. The mock on-premises network and the hub network are connected using Azure Virtual Network gateways to form a site-to-site connection. This configuration is very similar to how you would connect your on-premises datacenter to Azure.

This deployment can take up to 45 minutes to complete. The recommended deployment method is using the portal option found below.

Use the following button to deploy the reference using the Azure portal.

Deploy to Azure

Once the deployment has been completed, verify site-to-site connectivity by looking at the newly created connection resources. While in the Azure portal, search for 'connections' and note that the status of each connection.

Screenshot showing the status of connections.

The IIS instance found in the spoke network can be accessed from the virtual machine located in the mock on-prem network. Create a connection to the virtual machine using the included Azure Bastion host, open a web browser, and navigate to the address of the application's network load balancer.

For detailed information and additional deployment options, see the ARM Templates used to deploy this solution.

Architecture

The architecture consists of the following components.

  • On-premises network. A private local-area network running within an organization.

  • Azure Stack. A network environment on an Azure Stack tenant subscription, running within an organization. The Azure Stack VPN gateway sends encrypted traffic across a public connection to virtual IP (VIP) addresses and includes the following components:

    • Gateway subnet. A special subnet required to deploy the VPN Gateway on Azure Stack.
    • Local network gateway. Indicates the target IP of the VPN gateway in Azure, as well as the address space of the Azure virtual network.
    • Site-to-site VPN tunnel. The connection type (IPSec) and the key shared with the Azure VPN Gateway to encrypt traffic.
  • VPN appliance. A device or service that provides external connectivity to the on-premises network. The VPN appliance may be a hardware device, or it can be a software solution such as the Routing and Remote Access Service (RRAS) in Windows Server 2012. For a list of supported VPN appliances and information on configuring them to connect to an Azure VPN gateway, see the instructions for the selected device in the article About VPN devices for Site-to-Site VPN Gateway connections.

  • Virtual network. The cloud application and the components for the Azure VPN gateway reside in the same virtual network.

  • Azure VPN gateway. The VPN gateway service enables you to connect the virtual network to the on-premises network through a VPN appliance or to connect to Azure Stack through a site-to-site VPN tunnel.. The VPN gateway includes the following elements:

    • Virtual network gateway. A resource that provides a virtual VPN appliance for the virtual network. It is responsible for routing traffic from the on-premises network to the virtual network.
    • Local network gateway. An abstraction of the on-premises VPN appliance. Network traffic from the cloud application to the on-premises network is routed through this gateway.
    • Connection. The connection has properties that specify the connection type (IPSec) and the key shared with the on-premises VPN appliance to encrypt traffic.
    • Gateway subnet. The virtual network gateway is held in its own subnet, which is subject to various requirements, described in the Recommendations section below.
  • Cloud application. The application hosted in Azure. It might include multiple tiers, with multiple subnets connected through Azure load balancers. For more information about the application infrastructure, see Running Windows VM workloads and Running Linux VM workloads.

  • Internal load balancer. Network traffic from the VPN gateway is routed to the cloud application through an internal load balancer. The load balancer is located in the front-end subnet of the application.

  • BastionAzure Bastion allows you to log into VMs in the virtual network through SSH or remote desktop protocol (RDP) without exposing the VMs directly to the internet. If you lose connectivity through the VPN, you can still use Bastion to manage the VMs in the virtual network.

Rollback conflict patch and apply PSU Patch in Oracle 12C RAC Environment Step by Step


In this document, In Two Node RAC enviroment while applying PSU patch on RAC Database Home, we encounter with conflict patch, we follow below steps

A) rollback conflict patch manually

B) Apply PSU using opatchauto on oracle home

C) apply overlay patch manually


Patch Overview

Types of Oracle Patches

Oracle regularly makes patches available to upgrade features, enhance security, or fix problems with supported software. The major types of patches are:

·         Interim patches - contain a single bug fix or a collection of bug fixes provided as required

·         Interim patches for security bug fixes - contain customer-specific security bug fixes

·         Diagnostic patches - intended to help diagnose or verify a fix or a collection of bug fixes

·         Bundle Patch Updates (BPUs) - a cumulative collection of fixes for a specific product or component

·         Patch Set Updates (PSUs) - a cumulative collection of high impact, low risk, and proven fixes for a specific product or component and Security Patch Updates

·         Security Patch Updates (SPU) - a cumulative collection of security bug fixes. SPUs were formerly known as Critical Patch Updates (CPU).

·         System Patch - contains several sub-patches in a format that can be used by OPatchAuto.

·         Merge Label Request (MLR) - a merge of two or more fixes. MLR creation requires a label for the new set of merged code and a Patch Set 

OPatch consists of patching utilities that help ensure your Oracle software stays current and secure. The utilities are:

·         OPatch: A Java-based utility that enables the application and rollback of patches to Oracle software.

·         OPatchauto: A patch orchestration tool that generates patching instructions specific to your target configuration and then uses OPatch to perform the patching operations without user intervention. Specifically, OPatchAuto can:

1.  Perform pre-patch checks.

2.  Apply the patch

3.  Start and stop the running servers.

4.  Perform post-patch checks.

5.  Roll back patches when patch deinstallation is required.

 

·         OPatchAuto automates patch application to the Grid Infrastructure (GI) cluster, by applying patches to both the GI and the managed Oracle Real Application Cluster (RAC) homes.

 

Prerequisite
============


1) Download Patch  From Oracle Support
2) Check Free Space in Clusterware Home file system (approx free space 15-22 GB and /tmp file system
¨ Check ACFS File Systems  if  it is available on node ,Please unmount it before starting patching clusterware or stopping clusterware
3) Check clusterware and database component status
 ps -ef|grep pmon
 ps -ef|grep tns
 crsctl check crs
crsctl status resource -t
 crsctl query crs activeversion
 crsctl query crs releaseversion
 crsctl query crs softwareversion
./crsctl check crs
 ps -ef|grep d.bin

4) Check opatch version and recommended to have latest  opatch and download it from oracle support (6880880) and unzip it in Grid Home after renaming Old Opatch folder
  We must use the OPatch utility version 12.2.0.1.17 or later to apply this patch for all platforms
5) run opatch lsinventory from grid home to check consistency and corruption of inventory
6) unzip downloaded patch from Grid user
7) run analyze command using opatchauto from root user after setting proper path, we must carefully give grid home path

9) apply patch from  opatchauto on grid home from Root user
10)verify patch details on Grid Home
11)
OPatch maintains logs for apply, rollback, and lsinventory operations.

OPatch Log files are located in

ORACLE_HOME/cfgtoollogs/opatch.

Each log file is tagged with the time stamp of the operation.

Each time you run OPatch, a new log file is created.

OPatch maintains an index of processed commands-and log files in the opatch_history.txt file
