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!

  1. Thanks! this worked for me

    I was installing Oracle 11gR2 on CentOS 7 and ran into the first problem listed here (ins_ctx)

    I ran the fix for both of them (my oracle home was a slightly different place) and then selected retry on my oracle installation and all good!

    Plus to note i had a bunch of pre-check failures which I ignored and continued.. 9 packages it couldn’t find I believe, which I had new versions of them or I couldn’t find them on yum

  2. I was installing Oracle 11gR2 on CentOS 7 like Mr Patrick, and your advice helped me well.
    Thank you very much.

  3. its not working for me. can anyone suggest any other workround. i am installing 11gR2 on RHEL 5. I got the below error.

    Error in invoking target ‘nmo’ of makefile ‘/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk’. See ‘/u01/app/oraInventory/logs/installActions2015-12-12_11-57-43AM.log’ for details.

    i have changed the below value in ins_emagent.mk

    $(MK_EMAGENT_NMECTL) -lnnz11

    but still issue persist. Plese suggest.

    1. Any updates for Ravi’s question above?

      1. The syntax is very important. Must have tabs instead of spaces for the changed lines.

  4. You might want to check all the pre-requisite checks that are done when installing. I know you can ignore them but sometimes that is bad 🙂 Also you can try using Centos6 or OEL6
