Infrastructure at your Service
We all know that security becomes…sorry, is one of the hottest topic when setting up IT environment. One basis for that is to be compliant with regulations or standards such as GDPR or CIS. What is not so well known, is that ODA already integrates some tool to support you for that.
To do some application and performances tests, I had to copy a database from a third party Linux server to an ODA X7-2M. Looks pretty simple on the paper, but 2 small challenges came into the game. The first was that of course the source database was in Non-OMF while ODA works fully in OMF. The second was that the source database is running 11.2.0.3 which is not supported and cannot be installed on the…
While supporting since several years ODAs of different generations and versions, we faced time to time some hardware alerts sent back by the ILOM. However all of them are not related to real hardware issues and are false positive. To get rid of them the solution is to reset them manually.
While deploying an ODA based on the DCS stack (odacli), it is mandatory to provide a “master” password at appliance creation. The web GUI provides for that a small tooltip which describes the rules applied on password management. However it looks like there is some flexibility with those rules. Lets try to check this out with some basics tests.
While playing with a brand new ODA X7-2M, I faced a strange behaviour after re-imaging the ODA with the latest version 12.2.1.2.0. Basically after re-imaging and doing the configure-firstnet the next step is to import the GI clone in the repository before creating the appliance. Unfortunately this command fails with an error DCS-10001:Internal error encountered: Fail to start hand shake to localhost:7070. Why not having a look on how to fix it…
Virtual Local Area Network (VLAN) have become since several years a standard in enterprise class networks. Most enterprises are now segregating their network, especially for security reasons, between server and user or prod and test or applications and backup and aso. In the new release of ODA we finally get the support for VLAN on the bare metal platform. This article will briefly demonstrate how these are managed using ODAADMCLI.
I got an interesting question today from a customer which created a database on ODA. He selected the template odb-04 which shows 32GB Memory but got a database with a 16GB SGA… Is it due to the PGA size, a limitation in the system, the huge pages usage which is reached or even a bug?
When working with resources on the Oracle public cloud, whatever it is IaaS or PaaS, the principle access method is based on SSH keys exchange. Once our instance is created this is going to be the first and only way accessing it. Of course afterward additional ports/services can be opened. However the question is how to manage these keys and how important are they?
I had to perform a duplicate database between 2 ODAs and was always facing an ORA-65500 at the begin of the RMAN operation. Looking a bit deeper in the log outputs pointed me out that it was due to some changes in the way RMAN makes the duplicate in 12c and cluster resources management.
As you know it is possible to install the ODA in a virtualized mode and to take avantages from all cores not licensed with Enterprise Edition for additional VMs. The question is what could we do with it and which performances could we expect… The answer to the first question is indeed pretty simple….almost everything. If you have and ODA X5-2 with the version 12.1.2.3.0 implemented in virtualized mode then you are running an OVM…
