Oracle Instant Client and SQL Plus on Snow Leopard or Lion

by Bruce on July 6, 2011

  • Download the 32 bit flavor of “basiclite”, sqlplus, the sdk, and jdbc (if you need it) from Note: as of 10.2, 64 bit works on snow leopard but not lion.
  • unzip the downloads and place them somewhere out of the way like /Applications/Develop/oracle  the files should be combined into a single folder.  In my case /Applications/Develop/oracle/instantclient_10_2
    this is a strange place, a personal quirk of mine, put it wherever you’d like, just make the appropriate adjustments below.

  • make links
    cd instantclient_10_2
    ln -s libclntsh.dylib.10.1 libclntsh.dylib
    ln -s libocci.dylib.10.1 libocci.dylib
  • setup some environment variables… edit your ~/.profile
    # oracle
    export DYLD_LIBRARY_PATH="/Applications/Develop/oracle/instantclient_10_2"
    export SQLPATH="/Applications/Develop/oracle/instantclient_10_2"
    export TNS_ADMIN="/Applications/Develop/oracle/network/admin"
  • setup a tnsnames.ora in /Applications/Develop/oracle/network (or elsewhere just fix TNS_ADMIN export line above)
  • populate it with something – you’re on your own here unless you happen to be using the ldstech oracle vm, then use this…
  • restart terminal and test a connection with something like sqlplus username@sid

The sdk component of the instant client download is needed for things like installing the ruby-oci8 gem. If you don’t you’ll get a message like…
Error Message: ‘/Applications/Develop/oracle/instantclient_10_2/sdk/include/oci.h’ does not exist. Install ‘Instant Client SDK’.

If you have no Oracle Database installed but using client services to connect to Amazon RDS,
how is that set up in the TNSNames.ora. My guess is:
SID = myinstance

Thanks, I just need a few more clues. The above seems helpful, I will try it. I have already connected with SQLDeveloper tool but I really do prefer working in SQL*Plus.
