I am using RHEL3 and RHEL4 in my production environment. Well, one of application need glibc-2.4 and later to run on it and I need to upgrade glibc-2.3 to glibc-2.4 or above.
Http (apache), vsftp, mysql, php, nfs, and some other 3rd party servers like tomcat are installed/configured on these machines. To be honest I dont have any down time but I will manage some downtime if it would be very necessary.
Can someone guide me the best and safest way to upgrade the glibc?
$ cat /etc/redhat-release
Red Hat Enterprise Linux ES release 3 (Taroon Update 9)
$ uname -r
$ rpm -qa | grep glibc
# cat /etc/redhat-release
Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
# uname -r
# rpm -qa | grep glibc
waiting for any help.
