I think it's but best if you follow Oracle's Note ID 880936.1 from metalink (Requirements for isntalling 11gR2 RDBMS on RHEL (and OEL) 5 on 32-bit x86") for example . I installed 11.2 onto RHEL5.5 without problems following the note. I don't saw in the note any reference to EL4 libs though, only to RHEL5 Regards, --Alvaro ________________________________ De: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] En nombre de Howard Latham Enviado el: martes, 21 de septiembre de 2010 12:24 Para: ORACLE-L Asunto: Install Enterprise on Redhat and oracle 11.2 g I am trying to install oracle 11.2 on rehdat 2.6.18-194 The packages I need don't seem to be available on Redhat specifically gcc-4.1.2.el4 anybody managed to install? -- Howard A.
