Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /u01/EP1/apps/tech_st/10.1.2/oui/lib/linux/liboraInstaller.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
