Impact on the system
This alert may affect the creation and performance of some projects.
Possible causes
The CPU utilization, memory usage, or disk usage is high.
The following table lists the limits of the CPU utilization, memory usage, and disk usage for the OceanBase Migration Service (OMS) server.
| Type | Description | Default value |
|---|---|---|
drcCfg.cpuUsedPercentThresHold |
The upper limit of the CPU utilization for the OMS server. When the CPU utilization exceeds the specified value, projects can no longer be created. | 0.85 |
drcCfg.memUsedPercentThresHold |
The upper limit of the memory usage for the OMS server, in percentage. When the memory usage exceeds the specified value, projects can no longer be created. | 0.80 |
drcCfg.diskUsedPercentThresHold |
The upper limit of the disk usage for the OMS server, in percentage. When the disk usage exceeds the specified value, projects can no longer be created. | 0.90 |
Troubleshooting procedure
Release unwanted data migration or synchronization projects to reduce the host load. You can also scale out the OMS cluster.
To modify the CPU utilization, memory usage, and disk usage thresholds, perform the following steps:
Log on to the OMS container.
docker exec -it ${CONTAINER_NAME} bashNotice
CONTAINER_NAMEspecifies the name of the container.In the
drc-cm.propertiesfile in the/home/admin/conf/cm/directory, add the parametersdrcCfg.cpuUsedPercentThresHold(default value: 0.85),drcCfg.memUsedPercentThresHold(default value: 0.80) anddrcCfg.diskUsedPercentThresHold(default value: 0.90) to specify thresholds.Restart the oms_drc_cm services of OMS.
supervisorctl restart oms_drc_cm
