Standalone Requirements

Before installing ASI in standalone mode, ensure the following prerequisites are verified.

---

Hardware (minimum per node)

Resource	Minimum	Recommended	Notes
CPU	4 vCPU	8+ vCPU	Higher core counts improve throughput and responsiveness.
Memory	8 GB	10–16 GB	Increase memory for larger deployments or high event volumes.

Resource requirements may vary based on the number of active users, integrations, and event processing throughput.
For production or busy environments, plan for additional CPU and memory capacity.

---

Filesystem (recommended separate mounts)

Component	Mount Point	Owner	Group	Permissions	Minimum Size
Application Files	/opt/ISS/asi	ppadmin	ppusers	0750	10 GB
Log Files	/opt/ISS/logs	ppadmin	ppusers	0750	20 GB

Separating application and log files helps improve performance and manageability.

Operating System

• RHEL, Rocky, or AlmaLinux 8+
• Ensure access to standard repositories for dependency installation.
• Review the supported OS and package versions in the
  Support Matrix.

---

Java

• ASI requires OpenJDK 17 or later.
• Java 17 must be configured as the default for both java and javac.

See the Java Setup reference page for installation and configuration instructions.

---

Database

• PostgreSQL 15+ with extensions:
  • pgcrypto
  • semver

For installation and configuration steps, refer to the
PostgreSQL Installation reference page.

---

Sudo Rules

The ppadmin user must have permissions to start, stop, restart, and check the status of ASI systemd units.

View the required entries on the
Sudo Rules reference page.

---

Networking

Ensure all required ports for standalone deployments are open and accessible.
Firewall rules must allow communication between ASI modules, external databases, and integrated systems.

See the
Standalone Networking reference for detailed port mappings and connectivity requirements.

Proceed once all prerequisites are verified and system resources are confirmed for your expected workload.
