Service Control and Status

Use the following commands to manually control the start-up and shutdown of the Gateway service and to query the running status:

RHEL/Rocky Linux 8 or RHEL/CentOS 7
systemctl start cloudgateway
systemctl stop cloudgateway
systemctl status cloudgateway

Java Runtime Parameters

The /etc/sysconfig/cloudgateway file contains the Java process memory settings and the maximum number of open file descriptors for Gateway.

Default Java Process Settings
HEAP_MIN=1024m
HEAP_MAX=1024m
MAX_OPEN_FDS=25000

Memory: While the default JVM heap memory settings work well for a small deployment, increase them for larger deployments handling a large transaction load for multiple tenants. The JVM heap memory is utilized for caching frequently used objects, authentication results, and other operational data.

Maximum File Descriptors: While the default maximum number of open file descriptors works well for a small deployment, increase the limit for larger deployments handling a large transaction load for multiple tenants. Network socket connections for the upstream clients plus the back-end connection pool comprises the majority of the open file descriptors during Gateway operations.

Server Firewall

The firewall rules from the default RHEL/Rocky Linux 8 or RHEL/CentOS 7 installation need to be changed to allow inbound client access to Gateway. Adjust the IPTABLES rules to allow inbound access for each front-end protocol or disable IPTABLES entirely. Execute the following commands to disable the operating system's firewall:

RHEL/Rocky Linux 8 or RHEL/CentOS 7
systemctl disable firewalld
systemctl stop firewalld

While it is valid to use IPTABLES in conjunction with Gateway, the service startup script issues a notice, if IPTABLES are enabled as a reminder since using them can be a source of confusion if inbound traffic to Gateway is blocked. Ignore this startup notice if the inbound rules to allow access are customized.
