Principal Propagation in cloud foundry

Thu, 06 Nov 2025 10:24:00 +0100

In Cloud Foundry, how to make a request from an application running on a subaccount, to an endpoint handled by another application running on a different subaccount and protected with Roles

official documentation at https://help.sap.com/docs/connectivity/sap-btp-connectivity-cf/user-propagation-between-cloud-foundry-applications

We first need to establish a SAML trust between account 2 and account 1, and then configure a destination that can propagate the user login from account 1 to account 2

Prepare the IdP Metadata for establishing trust

Download the certificate of subaccount 1 by clicking Export in Connectivity -> Destination Trust

it could be required to generate the trust first

In #SAP #Datasphere, you have the need to write to a table created in the OPENSQL schema equivalent of the space By default, datasphere operations like Data flow have Read only access to the table defined in the OPENSQL schema

see https://help.sap.com/docs/SAP_DATASPHERE/be5967d099974c69b77f4549425ca4c0/7eaa370fe4624dea9f182ee9c9ab645f.html?locale=en-US

In order to GRANT Write access, a procedure GRANT_PRIVILEGE_TO_SPACE must be run by the OPENSQL user

running it with the Console user does not return an error, but it does nothing

Kubernetes on Ubuntu22.04

https://www.learnlinux.tv/how-to-build-an-awesome-kubernetes-cluster-using-proxmox-virtual-environment/

System configuration

Using #Ubuntu sever 22.04

Create the initial configuration:

sudo mkdir /etc/containerd
containerd config default | sudo tee /etc/containerd/config.toml

For this #kubernetes cluster to work properly, we’ll need to enable SystemdCgroup within the configuration. To do that, we’ll need to edit the config we’ve just created:

sudo nano /etc/containerd/config.toml

Within that file, find the following line of text:

[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
SystemdCgroup = true

Disable swap

sudo swapoff -a

Enable bridging

To enable bridging, we only need to edit one config file:

Calcolo KPI riferiti ad una risorsa

Qui di seguito le formule per calcolare gli indicatori Availability, Perfomance e Qualità in un turno per una determinata risorsa. Le formule sono comunque generalizzabili per intervalli di tempo diversi ( ad esempio l’ora ). E’ solito usare il turno come campione per analisi storiche, mentre unità più piccole solo per analisi puntali come il turno in corso.

Availability

L’indicatore Availability è determinato dal rapporto della disponibilità effettiva di una risorsa a produrre rispetto al tempo previsto Abbiamo quindi a numeratore la durata del turno ridotta di tutti i fermi ( ossia tutto il tempo in cui la macchina era disponibile ), mentre a denominatore la durata del turno ridotta dei fermi pianificati
