What Do I Do If the Message "transfer containerList_DB.json failed." Is Displayed?

Failed to transfer the "containerList_DB.json" file from the client login/northbound IP node to the inter-node communication node. Check the network connection of the client login/northbound IP node.

What Do I Do If the Message "check database login failed!" Is Displayed?

The database password for initial NCE installation is a random password. Ensure that you have logged in to the management plane to reset the password during commissioning. For details, see "User Security Management > Password Management > Database User > Changing Database User Passwords" in "iMaster NCE Administrator Guide".

Check whether the database of the failed node can be logged in to using the planned parameters.

Note: {python}，{dbPwd} and {port} are variables. Replace them with the planned or obtained values.

On the U2000 node, run the following command: su - dbuser -c 'isql -Udbuser -P{dbPwd} -SDBSVR'

If NCE is deployed in centralized mode, log in to the NMS_Server node.

Obtain the "port" parameter by running the following command: cd /opt/oss/NCE/apps/ISService/etc/sysconf; cat *.json | grep "readPort"

Obtain the "Host" parameter by running the following command: cd /opt/oss/NCE/apps/ISService/etc/sysconf; cat *.json | grep "accessHost"

Obtain the "DBuser" parameter by running the following command: cd /opt/oss/NCE/apps/ISService/etc/sysconf; cat *.json | grep "\"user\""

Then, run the following command: export LD_LIBRARY_PATH=/opt/zenith/app/lib/:/opt/zenith/app/add-ons/; export GSDB_HOME=/opt/zenith/app/; cd /opt/zenith/app/bin; ./zsql {DBUser}/{DBpwd}@{Host}:{port}

If NCE is deployed in distributed mode, log in to the NMS node and switch to user root.

Obtain the "python" parameter by running the following command: ls /opt/oss/rtsp/python*/bin/python | head -n 1

Obtain the "port" parameter by running the following command: {python} {/opt/migrate If the migration root directory has been modified, replace it with the new directory.}/cbb/checkdb/domain_db_check.py 'DB' /opt/migrate/containerList_DB.json | awk '{print $1}'

Obtain the "Host" parameter by running the following command: {python} {/opt/migrate If the migration root directory has been modified, replace it with the new directory.}/cbb/checkdb/domain_db_check.py 'DB' /opt/migrate/containerList_DB.json | awk '{print $2}'

Obtain the "DBuser" parameter by running the following command: {python} {/opt/migrate If the migration root directory has been modified, replace it with the new directory.}/cbb/checkdb/domain_db_check.py 'DB' /opt/migrate/containerList_DB.json | awk '{print $3}'

Then, log in to the DB node and run the following command: export LD_LIBRARY_PATH=/opt/zenith/app/lib/:/opt/zenith/app/add-ons/; export GSDB_HOME=/opt/zenith/app/; cd /opt/zenith/app/bin; ./zsql {DBUser}/{DBpwd}@{Host}:{port}
