Have you always attached an OCI Block Volume to a Compute Instance? If yes, I assume by console or OCI CLI and then executed manually the iSCSI commands to attach the device on OS level. But wait, here is a magic way to attach the Block Volume – by the Oracle Cloud Agent. Prerequisites Attached Service Gateway in VCN Oracle Cloud Agent software installed on the instance Enable the Block Volume Management plugin Verify Compute Instance disk status Create a Block Volume and attach Block Volume to Compute Instance OCI Tool oci-iscsi-config The OCI CLI method – the expressway If you want to auto-attach a high-performance block volume (multipath enabled) or a block volume where auto-tune is enabled, these two…

Oracle Cloud Infrastructure – Identity Service Vulnerability – Verify your Accounts NOW!
Today I was called by an allied sales from Oracle Switzerland (thanks Andreas). The main contact of the OCI tenant got an email in case of an identity service vulnerability in the past days. As I am not the main contact but the technical admin, I asked the tenant contact. An indeed, there was a mail arrived at 14th of June which was not forwarded to me. Oracle Security Notification for Oracle Cloud Infrastructure (OCI) Identity Service vulnerability CVE-2022-21503 (Doc ID 2861245.1) As a result of this vulnerability, administrators and their designees with read-access to the OCI audit-records in your tenancy could have viewed some credentials in clear text. These administrators and their designees could have used such credentials to…
Read MoreOracle Cloud Infrastructure OS Management – A small Update Script
This happens when not reading the docs until the end. I was searching for an automated OS Management patch job to patch my Oracle Cloud Infrastructure compute instances. Thanks on Twitter to @svilmune, @dhoogfr and @patrickjoss, who show me the menu in the OCI GUI and yes, there is a scheduler. In the meantime, I wrote a small bash script based on the OCI-CLI and instance principals. Credits to Iterating OCI CLI list data in bash (apextips.blogspot.com). Script #!/bin/bash set -e # set compartment comp=ocid1.compartment.oc1..aaaaaaaaoqti273775l2ye4xv4yqi35bcon3o4qb64yqfaxyj2jdagnvtsja # start check echo “” echo “———————————————————————————” echo “OCI OS Management Update Check $(date)” echo “———————————————————————————” #list OSMS registered instances managedinstanceList=$(oci os-management managed-instance list -c $comp –auth instance_principal) for i in $(echo “$managedinstanceList” | jq…
Read MoreOracle Cloud Infrastructure Quick Tip – Use the Bastion Service with MobaXterm
Mobatek’s MobaXterm is my favorite terminal for the daily work. It supports a lot of protocols like SSH, RDP, VNC, integrates X11 and SFTP and many more. And, MobaXterm can be used to connect to your OCI compute instance by the Oracle Cloud Infrastructure Bastion Service and the Managed SSH Session feature. Prerequisites OCI Compute Instance running in a private subnet OCI Bastion plugin enabled on Compute Instance – be patient when you enable it for the first time and fulfill the requirements for the agent The VCN has a Service Gateway attached The Subnet allows network connection from the Bastion Service private endpoint IP address – See Allowing Network Access From the Bastion (oracle.com) Link: Oracle Cloud Infrastructure Documentation…
Read MoreOracle Database Appliance – let’s backup to the Oracle Cloud Infrastructure Object Storage
This blog post describes the setup for an Oracle Database Appliance ODA database backup by RMAN to the Oracle Cloud Infrastructure. Basically there are three destinations for backup and recovery possible: • Oracle Fast Recovery Area (FRA) disk – the Internal FRA • Network File System (NFS) location – external FRA • Oracle Cloud Infrastructure Object Storage – Oracle Object Storage When using backup to the Oracle Cloud Infrastructure Object Storage, the Oracle Database Backup Cloud Service module (opc_installer.jar) is configured in the background. A configuration can be created by the ODA browser interface or by command line tool odacli – what I prefer. When you have already worked with the Oracle Database Backup Service and the OPC module, the…
