Oracle 9205 RAC RHEL3ES We have; 2.4.21-4.ELsmp and want/need to upgrade to 2.4.21-15; "15". OK Metalink says; Requirements for Installing Oracle 9iR2 on RHEL3 ... * Linux kernel version would be 2.4.21-4.EL But no mention of "maximum" (minimum is implied). I have looked in my own notes/docs, more on Metalink and further on OTN, but nothing on "maximum kernel for Oracle 9iR2". (I do not have the original installation guide...looking for it now). Also I run OCFS and appears under the current OCFS version we max out on/for kernel "2.4.21-15"...so we will not go higher (right now). Finally, what makes the "Hugmem kernel" different than "SMP kernel" and should I care? Only ever run "Uniprocessor" and "SMP" kernels. Thanks, Chris Marquez Oracle DBA PS <OTN COMPLAINT> Anyone notice how OTN is full off 10g help/docs but seems to have left all 9i DBA's in the cold! Would be nice to be able to reference without upgrading. http://www.oracle.com/technology/tech/linux/install/index.html The Oracle-on-Linux Installation Menu <OTN COMPLAINT>
