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 memcpy@GLIBC 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!
