Oracle by Example brandingSetting Up Oracle Enterprise Manager 13.4 on Oracle Cloud Infrastructure

section 0Before You Begin

This tutorial guides you through the required steps for creating a stack on Oracle Cloud Infrastructure Resource Manager and using it to deploy either Single or Multiple node Enterprise Manager setup. The time to complete this setup is approximately 20 minutes for Single node and approximately 3 hours for a Multi-Node deployment.

Overview

Oracle Enterprise Manager Cloud Control is a complete, integrated, business-driven management solution for traditional and cloud environments. It takes advantage of the built-in management capabilities of the Oracle stack and enables monitoring and management of your entire infrastructure from a single console. This allows for unprecedented efficiency gains and a dramatic increase in service levels.

This version of Oracle Enterprise Manager 13.4 on Oracle Cloud Infrastructure can be deployed on both Single and Multi-Node configurations allowing you to tailor Oracle Enterprise Manager to your specific infrastructure needs. Features include:

  • Ability to create and define your own OCI resources.
  • Credentials for Enterprise Manager and Databases can be configured at spin up time.
  • OMR is on the latest version of 19c Pluggable database that is also TDE (Transparent Data Encryption) enabled, ensuring safety on the Cloud.
  • Scalability: OMS Nodes and Bastion can be scaled to fit your needs by re-running the stack and selecting a new shape for both. This applies for both Single and Multi-Node deployments.
  • Enterprise Manager 13.4 on Cloud Infrastructure uses the latest OCI linux image: OL 7.

    VM.Standard 2.16 VM.Standard 2.8, 2.16, 2.24 VM.Standard 2.16 >=1,000 >=10,000 >=25,<50

    Example: If you wanted to manage a deployment of up to 100 targets, choose the Small deployment. The supported shapes for Small deployments are: VM.Standard 2.4, 2.8, 2.16, VM.DenseIO2.8, 2.16; VM.Standard.E2.2, E2.4, E2.8 and the recommended shape is: VM.Standard2.4.
    For additional resources on Enterprise Manager sizing information, see Enterprise Manager Cloud Control Sizing in Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.

  2. Ensure that your Oracle Cloud Infrastructure account has the correct Service Limits for the shapes and block storage adequate for the Enterprise Manager sizing you wish to deploy. When you sign up for Oracle Cloud Infrastructure, a set of service limits are configured for your tenancy. The service limit is the quota or allowance set on a resource. For more information on Service Limits including: Viewing Your Service Limits, Quotas, and Usage; see: About Service Limits and Usage.
  3. Create Compute resources, the following is a comprehensive list of source requirements for Single node (Simple) and Multi-Node (Small, Medium & Large) configurations:
    OCI Resource Single Node (Simple)
    VCN 1 - for "Create new VCN" option
    For more information see DNS in Your Virtual Cloud Network.
    Compute 1 - for public subnet / 2 for private subnet
    OCI Resource Multi-Node (Small, Medium, Large)
    VCN 1 - for "Create new VCN" option
    For more information see DNS in Your Virtual Cloud Network.
    Compute 4 - for public subnet / 5 for private subnet
    Oracle Database VM.Standard2 OCPU Count : depends on the VM shape
    Example: Choosing a VM.Standard2.4 - would translate to 4 OCPUS (for Multi-node; as its 2-node RAC)
    Oracle Cloud Infrastructure Load Balancing service 1 for chosen shape
    Block Volume Storage 1 for each OMS node
    Shared File Storage (NFS) File System - 1 / Mount target - 1

    Note: If you have more than one VCN in your environment, choose a CIDR that does not overlap for peering purposes. Peering is not possible if VCN CIDR's match, for more information see: VCNs and Subnets.

  4. Oracle recommends the following storage disk space:
    • Single Node: 400GB boot volume storage
    • Multi-Node (all sizes): 100GB block volume storage (default)
    For more information, see Oracle Cloud Compute Services.

  2. Enterprise Manager is configured by default with secured out-of-box with default WLS demo certificates, you will need to update these Enterprise Manager/WLS Certificates to properly secure your environment. For further information see: EM 13c, 12c: How to Configure Enterprise Manager's WebLogic Server (WLS) for Secure Socket Layer Certificates (Doc ID 2220788.1).
  3. A boot volume backup must be taken immediately after deployment and at regular daily or weekly intervals, this is where Simple Enterprise Manager and Database (OMR) deployments are done. For more information see: Overview of Boot Volume Backups.

Note: If a private subnet is used for Enterprise Manager, access to the console URL will be using a tunnel running on the bastion host.


section 3Deploy Enterprise Manager in a Multi-Node Configuration

To deploy Oracle Enterprise Manager on a Multi Node setup, follow these steps. Prerequisites are outlined in Step 1.

Multi-Node deployments can be setup with Small, Medium or Large Enterprise Manager deployments on a new or existing VCN.

Recommended Setups for Multi-Node Deployments

Multi-node deployments can be set up for High Availability; the following configurations are required within the network topology to achieve this:

  • Oracle Cloud Infrastructure Load Balancing service: The Load Balancer nodes will be on different Availability-Domains for High Availability.
  • Oracle Management Service: Choose different Availability-Domains for each OMS node if you require High Availability.
  • OMR: The OCI Database System provides an option to have nodes on different Fault domains but will be on the same Availability-Domains.

  • Oracle Cloud Infrastructure Load Balancing service can be placed either in public or private subnet.
  • The bastion host (subnet-3) is required and always deployed since both Enterprise Manager and Database are deployed in a private subnet.

The following diagrams capture High Availability deployments in Level-3 mode of Enterprise Manager. All OMS and OMR Database nodes are active in this configuration:

Port List and Multi-Node Post Deployment Steps

  1. Review and make a note of the following ports that Enterprise Manager on OCI will use:
    Component Service Source Port Range Destination Port for Multi-node Description
    Bastion SSH "0.0.0.0/0" TCP/22 Connecting to EM Console via Bastion SSH tunnel (Not needed if Load Balancer is public):
    ssh [-i private_key] -L localhost:5443:LBaaS_Private_IP:443 opc@bastion_public_ip
    Connecting to OMS/DB nodes:
    ssh -i private_key opc@oms/db privateip -o "proxycommand ssh -W %h:%p -i private_key opc@bastionhost"
    Load Balancer Console Public Load Balancer: "0.0.0.0/0"
    Private Load Balancer: VCN CIDR
    TCP/443
    Load Balancer Agent Upload Public Load Balancer: "0.0.0.0/0"

    Private Load Balancer: VCN CIDR
    TCP/5443
    Enterprise Manager SSH Bastion & EMDB subnet CIDR TCP/22
    Enterprise Manager Console VCN CIDR TCP/7799 EMCLI will also be routed via Load Balancer.
    Enterprise Manager Admin Server EMDB subnet CIDR TCP/7101 WebLogic Administration should happen using OMS nodes
    Enterprise Manager Node Manager EMDB subnet CIDR TCP/7401
    Enterprise Manager Managed Server / JVMD Load Balancer and EMDB subnet CIDR TCP/7301
    Enterprise Manager Agent Upload VCN CIDR TCP/4900
    Enterprise Manager Agent Listen (OMS and Database Nodes) EMDB subnet CIDR TCP/3872
    Database DB Listener EMDB subnet CIDR TCP/1521
    Database DB Nodes Bastion and EMDB subnet CIDR TCP/22
    Database DB Nodes (ONS/FanManager) EMDB subnet CIDR TCP/6200
    NFS NFS Service EMDB subnet CIDR UDP/111
    UDP/2048
    TCP/111
    TCP/2048-2050
  2. Enterprise Manager is configured by default with secured out-of-box with default WLS demo certificates, you will need to update these Enterprise Manager/WLS Certificates to properly secure your environment. For more information and detailed instructions see: EM 13c, 12c: How to Configure Enterprise Manager's WebLogic Server (WLS) for Secure Socket Layer Certificates (Doc ID 2220788.1).
  3. A Backup must be taken immediately after installation and at regular daily or weekly intervals. Enterprise Manager deployments are done on a block volume, and OMR is deployed on an OCI Database. For more information and detailed instructions see: Overview of Block Volume Backups and Backing Up a Database.
    Shared storage for the software library and BI Publisher are handled via NFS, this allows for storage that is inherently redundant with resilient data protection from OCI and can be excluded from the backups.

Note:

  • If the SSH keys for logging into the bastion, OMS or Database system needs to be rotated, DO NOT overwrite other public keys in the authorized_keys file that is used by stack. If these keys are flashed these keys OMR will loose access, only rotate public keys owned by end user.
  • If a private subnet is used for Load balancers, access to the console URL will be using a tunnel running on the bastion host.
  • The CIDR of the new regional private subnet to create the Enterprise Manager and Database instances should not overlap with 192.168.16.16/28. Also the netmask should be at least 28 or larger. Example: 10.0.1.0/28. For more information see: Network Setup for DB Systems.

Steps to Manually Enable Data Guard

This is an optional step, if your Multi-Node deployment requires Data Guard or you are deploying a High Availability deployment follow these steps:

  • Enable dataguard on the OMR database within the same Region, VCN, Subnet with Network Security Group (NSG); but on a different availability domain from the primary database. For detailed instructions see: Using Oracle Data Guard.
  • High Availability for Enterprise Manager on Cloud Infrastructure can be enabled by creating a Role Based Server and updating the connection URL in Enterprise Manager. For more information see: Connect Descriptor Considerations in Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide.
