Hi all,  

when startup my BD i have ora-27123 unable to attach to chared memory segment, so i run the HCVE to check for config failures ( Doc ID 250262.1).

in the output i get:

--RDA Results --

Failure Summary

Rule Description Result Action

A00125 This rule checks that the soft limit for the size of the stack segment is set to 10240 or higher and the hard limit for the size of the stack segment is set to at least 10240 and not greater than 32768. For details about configuring this parameter, see the Oracle Database Installation Guide 11g Release 2 (11.2) for Linux. HardHigh Decrease the hard limit for stacksize to 32768 or lower, but not less than 10240.

Howdy, Stranger!
