IOC Description
IOC Deployment
In this section, we provide IOC deployment details such as the App hosting the PLL IOCs, as well as the IOC names and the assigned CPUs in both Dev and Production.
IOC Repository
The IOC is housed by the masterSource App. The intended released tag in Production is R2.2.3.
| IOC App Name | App Version |
|---|---|
| masterSource | R2.2.3 |
Deployment In Production
The configuration used in Production is seen below.
| IOC Name | CPU Name |
|---|---|
| sioc-sys0-ms12 | cpu-li20-ms01 |
Deployment In Dev
The configuration used in Dev is seen below. As of now, there is no designated test stand in Dev.
| IOC Name | CPU Name (Intended) |
|---|---|
| sioc-b084-ms12 | cpu-b084-sp12 |
