GAUSS-52000 - GAUSS-52999
GAUSS-52000 - GAUSS-52099
GAUSS-52000: "Failed to obtain time zone information about the cluster node."
SQLSTATE: None
Description: Failed to obtain the time zone of the cluster node.
Solution: Check whether the time zone can successfully obtain command date -R.
GAUSS-52001: "Time zone information is different among cluster nodes."
SQLSTATE: None
Description: Nodes in the cluster use different time zones.
Solution: Use the date command to unify time zones of different nodes.
GAUSS-52100 - GAUSS-52199
GAUSS-52100: "Failed to obtain cluster node character sets."
SQLSTATE: None
Description:Internal system error.
Solution:Contact technical support.
GAUSS-52101: "Character sets are different among cluster nodes."
SQLSTATE: None
Description: Character sets are different among cluster nodes.
Solution: Manually write the required character set forcibly on each node to the /etc/profile file.
GAUSS-52102: "The parameter [%s] value is not equal to the expected value."
SQLSTATE: None
Description: The parameter value is not equal to the expected value.
Solution: Set the parameter value to the expected value.
GAUSS-52103: "Failed to forcibly make the character sets to take effect."
SQLSTATE: None
Description: Failed to force the character set to take effect.
Solution: Reinstall the character set.
GAUSS-52200 - GAUSS-52299
GAUSS-52200: "Unable to import module: %s."
SQLSTATE: None
Description: Using the default Python execution tool of the system results in imported package errors because the database that Python depends on is lacked.
Solution: Use the Python execution tool of the installation package and go to the directory after the decompression using **./**Tool name to run the command.
Take the pre-processing script as an example:
Go to the directory for storing tool scripts:
cd /opt/software/mogdb/script
Run the ./gs_preinstall script:
./gs_preinstall -U omm -G dbgrp -X /opt/software/mogdb/clusterconfig.xml --alarm-type=5 --root-passwd=Gauss_234
GAUSS-52201: "The current python version %s is not supported."
SQLSTATE: None
Description: The default Python OS is not 2.6.X or 2.7.X.
Solution: Use the default Python compiler in the OS.
GAUSS-52300 - GAUSS-52399
GAUSS-52300: "Failed to set OS parameters."
SQLSTATE: None
Description: Failed to configure OS parameters.
Solution:Contact technical support.
GAUSS-52301: "Failed to check OS parameters."
SQLSTATE: None
Description: Failed to check OS parameters.
Solution: Check whether the uname -r 2>/dev/null command is available. Check whether the grep -Er '' /etc/keepalived/keepalived.conf command is executable. Check whether Python and the multiprocessing module have been installed.
GAUSS-52400 - GAUSS-52499
GAUSS-52400: "Installation environment does not meet the desired result."
SQLSTATE: None
Description: The installation environment does not meet the requirements.
Solution: Use gs_checkos to check OS configurations and ensure that it meets the requirements.
GAUSS-52401: "On systemwide basis, the maximum number of %s is not correct. the current %s value is:"
SQLSTATE: None
Description: The maximum amount of semaphore in a semaphore set, the maximum number of semaphore sets, or the maximum amount of semaphore is incorrect. The current %s value is:
Solution: View the semaphore obtained from cat /proc/sys/kernel/sem and check whether SEMMSL, SEMMNI, or SEMMNS meet the requirements.
GAUSS-52402: "IP [%s] is not matched with hostname [%s]. \n"
SQLSTATE: None
Description: The IP address does not match the host name.
Solution: Check whether the IP address matches the host name. If they are not matched, modify the /etc/profile file.
GAUSS-52403: "Command "%s" does not exist or the user has no execute permission on %s."
SQLSTATE: None
Description: The command does not exist or you do not have the execution permission.
Solution: Check whether the command exists. Ensure that you have the execution permission.
GAUSS-52500 - GAUSS-52599
GAUSS-52500: "Failed to delete regular tasks."
SQLSTATE: None
Description: Failed to delete regular tasks.
Solution:Contact technical support.
GAUSS-52501: "Run %s script before executing this script."
SQLSTATE: None
Description: Another script needs to be run before you execute this script.
Solution: Check the execution sequence of the scripts.
GAUSS-52502: "Another OM process is being executed. To avoid conflicts, this process ends in advance."
SQLSTATE: None
Description:Internal system error.
Solution:Contact technical support.
GAUSS-52503: "Failed to execute checkRunStatus.py. Error: %s"
SQLSTATE: None
Description:Internal system error.
Solution:Contact technical support.
GAUSS-52600 - GAUSS-52699
GAUSS-52600: "Can not obtain any cluster ring."
SQLSTATE: None
Description: Failed to obtain a ring from the cluster.
Solution: Check whether the node information in the XML file is correctly configured.
GAUSS-52601: "Redistribution failed due to user request."
SQLSTATE: None
Description: Redistribution failed due to user requests.
Solution: Check whether users have performed invalid operations during the scale-in or scale-out process.
GAUSS-52602: "There is no CN in old nodes. "
SQLSTATE: None
Description: No CN is available on old nodes.
Solution: Check whether the CN is configured in the XML file and whether the cluster status is normal.
GAUSS-52603: "There is no CN on the contraction of the remaining nodes."
SQLSTATE: None
Description: No CN exists on the remaining nodes after the scale-in.
Solution: Check whether a normal CN is available on the remaining nodes after the scale-in.
GAUSS-52604: " Parameter '-r'[%s] can not be more than the numbers of cluster ring[%s]."
SQLSTATE: None
Description: The number of the -r parameters cannot exceed that of the cluster rings.
Solution: Check whether the number of the -r parameters in the gs_shrink command exceeds that of cluster rings configured in the XML file.
GAUSS-52605: "Can not contract local node(%s). "
SQLSTATE: None
Description: The local node cannot be scaled in.
Solution: Ensure that the node where the scale-in command is executed has been configured in the XML.
GAUSS-52606: " Contract too many nodes. It should left three nodes to format a cluster at least."
SQLSTATE: None
