GAUSS-52400 : "Installation environment does not meet the desired result."

SQLSTATE: None

Description: The installation environment does not meet the requirements.

Solution: Configure the installation environment to ensure 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:

1. View the semaphore obtained from cat /proc/sys/kernel/sem and check whether SEMMSL, SEMMNI, or SEMMNS meet the requirements. For example:

   1 2	cat /proc/sys/kernel/sem 250 32000 32 128

   

   250 SEMMSL max semaphores per array Maximum number of semaphores in a semaphore set

   32000 SEMMNS max semaphores system wide Maximum number of total semaphores

   32 SEMOPM max ops per semop call Maximum number of semaphores that can be called in a semaphore set

   128 SEMMNI max number of arrays Maximum value of a semaphore set

2. Take the SEMMNI parameter as an example. Run the ipcs -a | wc -l command:

   1 2	ipcs -a | wc -l 144

3. 144 is greater than 128. The parameter value is out of range. Run the following command to modify the parameter:

   1	echo "500 641280 500 500" > /proc/sys/kernel/sem

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.
