This topic describes how to perform a pre-upgrade check for OBServer nodes by using obshell-sdk-python.
Note
We recommend that you read Quick start for a better understanding of how to use obshell-sdk-python.
Considerations
Make sure that OceanBase Shell (obshell) runs normally.
Make sure that the node corresponding to the client instance that you use belongs to the cluster to be upgraded.
Sample code
Synchronous task execution
Asynchronous task execution
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("****"))
# Perform a pre-upgrade check for OBServer nodes in the cluster.
client.v1.upgrade_ob_check_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("****"))
# Perform a pre-upgrade check for OBServer nodes in the cluster.
client.v1.upgrade_ob_check("4.2.2.0", "xxx.el7")
# Wait for the task to complete.
client.v1.wait_dag_succeed(dag.generic_id)
