Upgrade agents

This topic describes how to upgrade the agents for OceanBase Shell (obshell) nodes in an OceanBase cluster by using obshell-sdk-python.

Considerations

• Make sure that obshell runs normally.

• Make sure that the node corresponding to the client instance that you use belongs to the cluster to be stopped.

Sample code

from obshell import ClientSet
from obshell.auth import PasswordAuth

# Create a client instance, with the IP address of "10.10.10.1" and the port number of 2886.
# Enter the root@sys password "****" for the cluster.
client = ClientSet("10.10.10.1", 2886, PasswordAuth("****"))

# Upgrade the agents.
client.v1.upgrade_agent_sync("4.2.2.0", "xxx.el7")

from obshell import ClientSet
from obshell.auth import PasswordAuth

# Create a client instance, with the IP address of "10.10.10.1" and the port number of 2886.
# Enter the root@sys password "****" for the cluster.
client = ClientSet("10.10.10.1", 2886, PasswordAuth("****"))

# Upgrade the agents.
client.v1.upgrade_agent("4.2.2.0", "xxx.el7")
# Wait for the task to complete.
client.v1.wait_dag_succeed(dag.generic_id)
