I have rather generic question. I am exploring some Linux application (especially Oracle 9.0.1) on FreeBSD starting from early RELENG-5.0. During the time I have upgraded FreeBSD in order to 5.1->5.5->6.0->6.1->6.2 and my Oracle database successfully survived all this transitions. Now being inspired the great performance improvements on multiprocessors configurations I am trying to switch to FreeBSD 7.0 version, moreover on AMD64 architecture. Must I expect some regression in support old Linux application here? Are some theoretical obstacles exists that linux application which successfully worked on FreeBSD from 5.0 up to 6.2 can not be running on 7.0 AMD64? Of course I ask this questions because I was encountered some troubles already, when I am trying to start Oracle server I'm getting: ORA-27122: unable to protect memory Linux Error:13: Permission denied the hint from Oracle: oerr ORA 27122 27122, 00000, "unable to protect memory" // *Cause: mprotect() call failed Linux environment which I am using is the same from FreeBSD 5.0 days - rh7. Of course Oracle is a black box and in any way is not intended to run in emulation environment, and possibly it is silly to hope to accomplish this quest. Nevertheless my question is where can I find information about what was changed in linux emulation environment from 6.2 to 7.0 or from i386 to AMD64? What are known limitations(regressions) of linux emulations in 7.0 AMD64? Thank you. Valery.
