In the previous blog post PCA X9-2 – Console Connection – How To – martinberger.com, I wrote how to connect to PCA running virtual machine by VNC viewer. If you have no VNC viewer available, the virtual machine is Linux based and only network connection to the management node is available, here is another way go get a console connection . In this case, no active Console Connection is required. Information Gathering Virtual Machine From the virtual machine you want to connect, get the Fault Domain and the OCID in the Service Enclave User Interface. In this example the virtual machine is running on FAULT-DOMAIN-1, in our case this is Compute Node 1. Compute Node IP Address On the active…

PCA X9-2 – Which Storage Type do you own?
Available Storage Types For the PCA X9-2, you can order two different storage types. High Capacity or High Performance. They are different in size and speed as described in this table. High Capacity – DE3-24C High Performance – DE3-24P – 20x 18 TB, SAS-3, 3.5-inch, 7200 RPM HDDs– 2x read SSD accelerator– 2x write SSD accelerator – 20x 7.68TB SAS-3 2.5-inch SSDs– 2x write SSD accelerator The question this week was, which type do we use in our PCA X9-2 setup. In a PCA X9-2, there is as ZFS Storage Appliance running as we already know for example from ZS7-2. Oracle uses the same architecture and the software, the main difference is, that the ZFSSA is completely integrated into the…
Read MorePCA X9-2 – Console Connection – How To
In a customer project, we have two Oracle Private Cloud Appliance X9-2 up and running. The management of a PCA X9-2 is almost like in Oracle Cloud Infrastructure. Even when the style of the user interface is not so cool. This week after a change on a virtual machine, the machine was not able to boot again. As in OCI, then Console Connection is the best way to troubleshoot the situation and gather more information. In this blog post I show you how to connect to a virtual machine from a Windows platform. See here for the virsh connection when no VCN viewer is available: PCA X9-2 – Console Connection – virsh Version Architecture Prerequisites Documentation – PCA 3.0.2 https://docs.oracle.com/en/engineered-systems/private-cloud-appliance/3.0/user-3.0.2/user-usr-compute.html#usr-instance-consoledisplay…
Read MoreOracle ZFSSA Storage Appliance – disabling SNMP service kills the Hybrid Comlumnar Compression functionality
In a customer project, we are running several ZS7-2 Oracle ZFS Storage Appliances ZFSSA in bundled with Private Cloud Appliances PCA. The ZFSSA is a very powerful storage solution with a lot of functionality like OISP (Oracle Intelligent Storage Protocol), or – when an ADVANCED COMPRESSION license is yours – Hybrid Columnar Compression HCC. But once in a day when I tried to create a Hybrid Columnar Compression enabled tablespace in a 19c pluggable database in our test system, I got this error: ORA-64307: Exadata Hybrid Columnar Compression is not supported for tablespaces on this storage type SQL> CREATE BIGFILE TABLESPACE ts_data_hcc_01 2 DATAFILE SIZE 200m AUTOEXTEND ON NEXT 10m MAXSIZE 100G 3 LOGGING ONLINE PERMANENT BLOCKSIZE 8192 EXTENT MANAGEMENT…
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…
