We have a situation where we need to fix a SAN disk issue on the target side of a Oracle 9.2.0.7 with Dataguard. The fix is to upgrade the kernel version from 2.6.42 to 2.6.55. However, we cannot get downtime right now to fix the source side. My feeling is that it is ok to update the target Linux server kernel for now, and they update the source side as time permits. The only thing I am advising is to relink Oracle. Any thoughts on this strategy?
