# Apply-Resource-Bundle-Cache-Config_688983031
|
|
## Purpose
|
|
|
|
The RDS CPU usage rate for resource bundle exceeds 5%. It is recommended to execute the runbook when the total RDS CPU rate is high.
|
|
|
|
## Introduction
|
|
|
|
There are 3 configmap keys added for Resource Bundle Local Cache in SMAX 24.3 version, this doc is used to provide scripts to apply this change.
|
|
|
|
## Add Configmap Keys
|
|
|
|
Run following cmd:
|
|
|
|
```
|
|
kubectl patch configmap itom-xruntime-infra-config -n <itsma_namespace> --type merge -p '{"data":{"RESOURCE_BUNDLE_HEAVY_TENANT": "<tenant_ids>", "RESOURCE_BUNDLE_MAX_SLIGHT_TENANT_SIZE": "10", "RESOURCE_BUNDLE_MAX_LOCALE_SIZE": "2"}}'
|
|
```
|
|
|
|
Replace <itsma\_namespace> and <tenant\_ids> with corresponding values. If there are multi heavy tenants, split them with space.
|
|
|
|
Here is a example:
|
|
|
|
```
|
|
kubectl patch configmap itom-xruntime-infra-config -n itsma-byqde --type merge -p '{"data":{"RESOURCE_BUNDLE_HEAVY_TENANT": "555500000", "RESOURCE_BUNDLE_MAX_SLIGHT_TENANT_SIZE": "10", "RESOURCE_BUNDLE_MAX_LOCALE_SIZE": "2"}}'
|
|
```
|
|
|
|
## Add env to platform pods
|
|
|
|
a.Create a patched yaml file and add env
|
|
|
|
```
|
|
spec:
|
|
template:
|
|
spec:
|
|
containers:
|
|
- name: itom-xruntime-platform
|
|
env:
|
|
- name: RESOURCE_BUNDLE_HEAVY_TENANT
|
|
valueFrom:
|
|
configMapKeyRef:
|
|
name: itom-xruntime-infra-config
|
|
key: RESOURCE_BUNDLE_HEAVY_TENANT
|
|
- name: RESOURCE_BUNDLE_MAX_SLIGHT_TENANT_SIZE
|
|
valueFrom:
|
|
configMapKeyRef:
|
|
name: itom-xruntime-infra-config
|
|
key: RESOURCE_BUNDLE_MAX_SLIGHT_TENANT_SIZE
|
|
- name: RESOURCE_BUNDLE_MAX_LOCALE_SIZE
|
|
valueFrom:
|
|
configMapKeyRef:
|
|
name: itom-xruntime-infra-config
|
|
key: RESOURCE_BUNDLE_MAX_LOCALE_SIZE
|
|
```
|
|
|
|
b.Apply patch-platform.yaml file for all platform pods
|
|
|
|
```
|
|
kubectl patch deployment itom-xruntime-platform -n <itsma_namespace> --patch-file patch-platform.yaml
|
|
```
|
|
|
|
All the platform pods(itom-xruntime-platform,itom-xruntime-platform-offline,itom-xruntime-platform-offline-ng,itom-xruntime-platform-readonly) need to apply this change.
|
|
|
|
## Validation
|
|
|
|
Go into platform pod, print env
|
|
|
|
```
|
|
echo $RESOURCE_BUNDLE_HEAVY_TENANT
|
|
```
|
|
|
|
Check the result is not empty.
|
|
|
|
## Verification
|
|
|
|
The RDS CPU usage rate for the resource bundle decreases compared to the value before applying the resolution after 1 working day.
