Installing the Grid DataBlade

The instructions here could apply to many DataBlades.

Create a new database

We'll need a database to work with (DataBlades are installed on a per-database basis). To do this, run

dbaccess - - <<!
drop database grdtest;
create database grdtest with buffered log;
!

Install the Grid DataBlade

On our system, this was simply a matter of extracting the Grid1010.tar.gz file into $INFORMIXDIR/extend, which created a directory called $INFORMIXDIR/extend/Grid.1.0.1.0. (with permissions 755)

Fix problems with blademgr

If running Red Hat 9.0, the supplied blade manager does not work. To fix this, use the following instructions (taken from https://www.metnet.navy.mil/~hofschnr/Informix/9.4UC2-and-9.0.html):

1. Download old versions of some shared libraries from here.
2. Make a new directory $INFORMIXDIR/lib/blademgr.
3. Extract the downloaded shared libraries into this directory.
4. Create symbolic links: ln -s ld-2.2.5.so ld-linux.so.2, ln -s libc-2.2.5.so libc.so.6, ln -s libnss_files-2.2.5.so libnss_files.so.2
5. Move the original blademgr executable $INFORMIXDIR/bin/blademgr into $INFORMIXDIR/lib/blademgr.
6. Create a shell script called blademgr (with permissions 755) in $INFORMIXDIR/bin to load the shared libraries and run the original executable:

#!/bin/sh
LD_LIBRARY_PATH=/opt/informix/lib/blademgr /opt/informix/lib/blademgr/blademgr

Register Grid DataBlade for the database

In order to use the Grid DataBlade, you will need to register both the Grid and the Spatial DataBlades with the database (the Spatial DataBlade can be installed straight off the rpm on the CD - see InstallingInformixSpatial). To register a datablade, run blademgr, then type register <blade name> <database name> (e.g. register spatial.8.20.UC1 grdtest, then register Grid.1.0.1.0 grdtest. The name of the DataBlade is the name of the directory in $INFORMIXDIR/extend).
