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. For example:
1 2

cat /proc/sys/kernel/sem 250 32000 32 128
NOTE:

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
Take the SEMMNI parameter as an example. Run the ipcs -a | wc -l command:
1 2

ipcs -a | wc -l 144
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"
