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

Then press the Retry button and it should install correctly!
