Install TOra with Teradata on Ubuntu11/30/2010
In my previous post, I wrote about compiling TOra with Teradata . Unfortunately, there are a couple additional steps to take on newer Linux distributions, like Ubuntu.
I am still using the 13.10 libraries. You can download the RPMs from
Teradata . Convert them to deb files using alien (simply
sudo alien [rpm]) and install them using
dpkg -i [deb file].
Configure and compile TOra. Add the --with-teradata flag to enable Teradata support.
Try logging in with TOra. If you get an error like "CLI2: ICULOADLIBERR(527): Error loading ICU libraries," make sure that the Teradata libraries have all of their dependencies met.
At the time of writing, the Teradata libraries still depend on libstc++5. This is an old library that is no longer distributed with Ubuntu. But you can grab a copy from the Debian archive . When a library is missing, it appears in ldd output like this:
$ ldd /opt/teradata/client/13.10/tdicu/lib/libicuuctd.so.36.0 linux-gate.so.1 => (0x0076d000) libicudatatd.so.36 => /usr/lib/libicudatatd.so.36 (0x00d41000) libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0x0023c000) libstdc++.so.5 => not found libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0x00255000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00adf000) libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x0027b000) /lib/ld-linux.so.2 (0x00d24000)
Also confirm that the rpm scripts successfully added a few lines to
/etc/profile. They should look like the following. Double-check the paths
before using, then run
TD_ICU_DATA=/opt/teradata/client/13.10/tdicu/lib; export TD_ICU_DATA # Added by tdicu 13.0 package COPLIB=/opt/teradata/client/13.10/lib; export COPLIB # Added by cliv2 13.0 package COPERR=/opt/teradata/client/13.10/lib; export COPERR # Added by cliv2 13.0 package
On the next login attempt, you may now get an error like
MTDP: EM_GSSINITFAIL(235): call to gss_init failed.
I had to run TOra with strace to figure out that it was trying to load something from /usr/teragss, which was empty. This might be an error from the rpm conversion, but it is quickly fixed with:
sudo mkdir -p /usr/teragss/redhatlinux-i386 sudo ln -s /opt/teradata/teragss/redhatlinux-i386/13.10.00.04/ /usr/teragss/redhatlinux-i386/client
Lastly (with any luck), you'll need a tdgssconfig.bin file. This appears to be a binary version of an xml file shipped with tdgss, but I am unable to run the tdgssconfig executable myself. There are even more incompatibilities with libstc++. Instead, I simply copied this file from the vmware Teradata Express image. You can use this file too, or your DBA might be able to provide a more suitable version.
Copy it to
Despite the hacking it takes to get it running, TOra actually works really well with Teradata. This process would be much easier on a Teradata-supported OS, but I like my Ubuntu. I'm sure they've got additional instructions somewhere, but this is how I managed to get it working as an outsider with no support.
