When installing SHRINE from scratch, we generally recommend these minimum requirements for best performance, as these are the conditions that we test the software in:
| Minimum | Recommended | |
| Operating System | RPM-based Linux | CentOS 7 Core |
Web Browser | Google Chrome 111 | Google Chrome 111.0.5563.147 or better |
| Processor | 2 cores | 4 or more cores |
| Memory | 4GB | 8GB |
| Hard Drive Space | 30GB | 100GB |
| Java JDK | Any JDK version "17.0.5" 2022-10-18 LTS | OpenJDK 64-Bit Server VM Zulu17.38+21-CA |
| Apache Tomcat | 9.0 | 9.0.73 |
| MariaDB | 5.5 | Ver 15.1 Distrib 5.5.68-MariaDB |
| i2b2 Version | 1.7.13 | 1.7.13 |
| Kafka (Optional) | 3.3.1 | kafka_2.13-3.3.1 |
| Apache Proxy (Optional) | 2.4.54 | 2.4.54 |
Do not install SHRINE and i2b2 on the same operating system or physical hardware. Both SHRINE's Tomcat and i2b2's Wildfly servers are optimized to make maximum use of a system's resources. Either can starve the other for processing time or memory to the point of stalling both of them.
