Recommended Memory Allocation for Signer
What is the recommended memory allocation for Security Server's signer component with respect to the host's available memory?
The recommended memory allocation for signer depends on the amount of RAM available on the host. In addition, also the type of host (virtual, physical etc.) and usage patterns of the Security Server effect on the most optimal amount of memory. The table below shows general recommendations regarding the amount of memory allocated for the signer component.
RAM on host (GB) | SIGNER_PARAMS value |
---|---|
4 | -Xms50m -Xmx100m |
8 | -Xms50m -Xmx150m |
16 | -Xms50m -Xmx200m |
31 | -Xms50m -Xmx200m |
The default memory allocation for signer is -Xmx50m. In production environments the allocation should be increased.
Please note that the step-by-step guides differ between X-Road 6 and X-Road 7. Therefore, it's extremely important to choose the right guide.
More information about the differences is available here.
Step-by-step guide for X-Road 7
Memory allocation for signer can be customized modifying the /etc/xroad/services/local.properties
configuration file.
Signer's default configuration is stored in /etc/xroad/services/signer.conf
which is always overwritten on version updates. Therefore, /etc/xroad/services/local.properties
must be used for overriding default configuration as the file is not overwritten during version updates. By default, /etc/xroad/services/local.properties
file is empty.
Open
/etc/xroad/services/local.properties
file for editing and make your changes onXROAD_SIGNER_PARAMS
variable value. For example, configuration of dynamic memory allocation of 50 - 200 MB (heap, max memory 200 MB, min memory 50 MB):XROAD_SIGNER_PARAMS=-Xms50m -Xmx200m
The size of the metaspace can be adjusted changing the value of
MaxMetaspaceSize
parameter. The value can be increased to 80m (-XX:MaxMetaspaceSize=80m
), if needed.Save the
/etc/xroad/services/local.properties
file after making the required changes.Restart the
xroad-signer
service.systemctl restart xroad-signer

Memory allocation for signer can be customized modifying /etc/xroad/services/local.conf
configuration file
Open
/etc/xroad/services/local.conf
file for editing and make your changes onSIGNER_PARAMS
variable value. For example, configuration of dynamic memory allocation of 50 - 200 MB (heap, max memory 200 MB, min memory 50 MB):SIGNER_PARAMS="$SIGNER_PARAMS -Xms50m -Xmx200m "
The size of the metaspace can be adjusted changing the value of
MaxMetaspaceSize
parameter. The value can be increased to 80m (-XX:MaxMetaspaceSize=80m
), if needed.
