dnsmasq split dns trick!

check the content of the file /etc/sysconfig/network

Make sure you have in here what the external dns name is.

HOSTNAME=mail.johnson.com

This line SHOULD be in accordance of the /etc/hosts file. If your server has an ip address like 192.168.4.1 then your /etc/hosts file should look like

127.0.0.1 localhost.localdomain localhost
192.168.0.19 mail.johnson.com mail

Install DNSMASQ

yum -y install dnsmasq

modify the following line in /etc/dnsmasq.conf

mx-host=johnson.com,mail.johnson.com,50

modify the /etc/resolv.conf as follows:

nameserver 127.0.0.1
nameserver 8.8.8.8

 

restart dnsmasq

/etc/init.d/dnsmasq restart

check your work

dig johnson.com mx

Oracle Database 11g install on Centos 7

Problem encountered when installing Oracle 11g on Centos 7

Google suggested this was a fairly common problem with machines with a newer GLIBC. Most of the suggested solutions didn’t work for me (writing a glib memcpy shim etc). Instead I was able to statically link this executable against the glibc archive which didn’t have the problem with the missing [email protected] reference.

yum install glibc-static.x86_64

yum install glibc-static.i686

vi /u01/app/oracle/product/11.2.0/dbhome_2/ctx/lib/ins_ctx.mk

ctxhx: $(CTXHXOBJ)

-static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a

I additionally had to patch the the ins_emagent.mk to link to the libnnz11 library:

vi /u01/app/oracle/product/11.2.0/dbhome_2/sysman/lib/ins_emagent.mk

Search for the line

$(MK_EMAGENT_NMECTL)

Change it to:

$(MK_EMAGENT_NMECTL) -lnnz11

Then press the Retry button and it should install correctly!
