PRVF-7543 : OS Kernel parameter "maxuproc" does not have proper value on node

PRVF-7543 : OS Kernel parameter "maxuproc" does not have proper value on node

Met an error PRVF-7543 during Oracle database 19c software installation on AIX 7.2 like this:

PRVF-7543 : OS Kernel parameter "maxuproc" does not have proper value on node "NodeName" [Expected = "16384" ; Found = "128"].

Looks like that an OS kernel parameter maxuproc does not meet the minimum requirement of Oracle database software installation. Let's check the current settings.

# lsattr -El sys0 -a maxuproc
maxuproc 128 Maximum number of PROCESSES allowed per user True

The current value of maxuproc is 128.

Solution

The solution is to increase maxuproc to 16384.
