    Install Python cx_Oracle on Solaris 11

    Jan Schreiber



      I really didn't expect this to be that hard:


      Just installing cx_Oracle on a fresh Solaris 11 box.


      root@zion11:~# python

      Python 2.6.8 (unknown, Feb 26 2014, 19:21:08) [C] on sunos5

      Type "help", "copyright", "credits" or "license" for more information.


      root@zion11:~# echo $ORACLE_HOME


      root@zion11:~# echo $LD_LIBRARY_PATH



      Okay, fine. Let's go to work:


      # which pip

      no pip in /usr/bin /usr/sbin /opt/csw/bin /bin /sbin

      # which easy_install

      no easy_install in /usr/bin /usr/sbin /opt/csw/bin /bin /bin


      Great. I am on Oracle hardware, using an Oracle OS and pre-installed python, and just want to connect to my Oracle database. Why isn't cx_Oracle pre-installed in the first place? Or am I just missing some pkg package I could use?


      But wait, luckily, there is OpenCSW.

      Well, okay, this is not at all the installed GCC version.

      Or, maybe something else:

      Any ideas?

        • 1. Re: Install Python cx_Oracle on Solaris 11

          I've prodded some Solaris folk to look at your post.


          cx_Oracle is 3rd party open source software so it's not totally

          surprising that it isn't pre-installed on Solaris.


          Regarding the DIY method at the end of your post, did you create the

          symbolic links mentioned in the Instant Client installation

          documentation? http://docs.oracle.com/database/121/LNOCI/oci01int.htm#LNOCI16174

          • 2. Re: Install Python cx_Oracle on Solaris 11

            I've built and installed cx_Oracle 5.1.1 for use on Solaris, but haven't put them into an IPS package - too many projects going on. Doing so is very much on my todo list (as is offering those changes upstream).


            In the meantime, here's what you need to know.


            Firstly - the pycc wrapper that we ship in Solaris is written assuming use of Solaris Studio compiler options. That's why you saw  "gcc: unrecognized option '-KPIC'" in the output above. To get past this, install the Solaris Studio compiler - it's available on pkg.oracle.com from the solarisstudio repository; please see Oracle Solaris Studio Downloads for details.


            Secondly - I had to create symlinks by hand in the extracted Oracle Instant Client directory after installing from the tarball. I'm not sure if you need to do that when installing pkg://solarisstudio/developer/solarisstudio-123/library/oic-libs and pkg://solarisstudio/developer/solarisstudio-123/oic. One thing the tarball option gives you is the opportunity to install the 64bit client libraries as well.


            Once I had the instant client bits installed, I ran the setup.py script like this:


            $ ORACLE_HOME=/opt/oracle/instant_client_11_2 LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2: python setup.py
