Review stack resources

After the stack creation completes, take a moment to review the resources that were created.

Review VCN details

Use the following steps to review the network resources created for Oracle GoldenGate Maximum Availability Hub.

To review network resources created:

1. Use the Oracle Cloud console navigation menu to navigate to Networking, and then Virtual Cloud Networks.
2. In the Virtual Cloud Networks list, select <cluster-prefix> VCN.
3. On the VCN details page, click Subnets to view the private and public subnet that were created.
4. In the VCN Information section of the VCN detail page, click DNS resolver.
5. On the Private resolver details page, click Associated private views to review the private view. Click goldengate_dns_view.
6. In the Private zones list, click goldengate.com.
7. In the Records section of the goldengate.com zone page, both the primary and standby dns records were added. Take note of the RDATA value for the primary cluster.

Review Compute Instances

Use the following steps to review the Compute Instances (nodes) created for Oracle GoldenGate Maximum Availability Hub.

To review the Compute Instances created:

1. Use the Oracle Cloud console navigation menu to navigate to Compute, and then Instances.
2. In the list of Instances, you can select a primary or standby node to view its details.

   Note:

   Depending on the cluster configuration chosen, a total of four nodes is created for primary and standby clusters, while two are created for primary only cluster configurations, and two created for the standby only cluster configurations. The naming conventions are as follows:

   • Primary cluster nodes:
     • <cluster-prefix>1-<node-prefix>1
     • <cluster-prefix>1-<node-prefix>2
   • Standby cluster cluster nodes:
     • <cluster-prefix>2-<node-prefix>1
     • <cluster-prefix>2-<node-prefix>2
3. Each node has public and private network interfaces. On the Instance's details page, click Networking. Review the information under Attached VNICs.

   Note:

   The IP address that was shown in the DNS record for the primary cluster is the same as shown in the list of IPv4 Addresses of the primary VNIC for <cluster-prefix>1-<node-prefix>1.
4. Each node also has attached block volumes. On the Instance's details page, click Storage to view the Attached Block Volumes:
   • cluster-gidisk: Storage volume for the Grid Infrastructure. This is shared between the two nodes in the cluster.
   • cluster-oggdisk: Storage volume for Oracle GoldenGate. This is shared between the two nodes in the cluster.

     Note:

     Automatic storage management cluster file system (ACFS) replication of this storage volume occurs between the primary and standby clusters.
   • <instance-name>-swap: This is dedicated to the node and not shared.

Review Block Volumes

Use the following steps to review Block Volumes created for Oracle GoldenGate Maximum Availability Hub.

To review Block Volumes created:

Note:

You can also view Attached Block Volumes for each Compute Instance (node) on the Storage page of the Compute Instance's details page.

1. Use the Oracle Cloud console navigation menu to navigate to Storage, and then Block Volumes.
2. On the Block Volumes page, all block volumes created as part of the stack job is listed here. Available block volume details depends on the cluster configuration created (primary only, secondary only, or both):
   • <cluster-prefix>1-oggdisk
   • <cluster-prefix>1-gidisk
   • <cluster-prefix>1-<node-prefix>1-swap
   • <cluster-prefix>1-<node-prefix>2-swap
   • <cluster-prefix>2-oggdisk
   • <cluster-prefix>2-gidisk
   • <cluster-prefix>2-<node-prefix>1-swap
   • <cluster-prefix>2-<node-prefix>2-swap

Next, monitor installation and startup.
