In Response To: Re: Faster Dbimport (GUSTAVO ECHENIQUE)

Gustavo:

The IIUG Software Repository is a library of software and scripts
contributed by Informix users. It resides on the IIUG web site at:
www.iiug.org/software. For managing the process, myexport & myimport use
dbaccess. However, for the actual data export/import it uses one of the
following:

- dbaccess for export/import using external tables (-E option available

only for Informix v11.50 and later).

- sqlunload/sqlreload from Jonathan Leffler's sqlcmd package for using

traditional UNLOAD and LOAD processing

- For export/import using the HPLoader they can use either:

- The Informix hpladmin utility (available first in v10.00 IB), or

- Ravi Krishna's myonpload utility.

For all of these methods myexport uses my dbschema replacement utility,
myschema, from my utils2_ak package. All of these packages, utils2_ak,
myonpload, and sqlcmd can be downloaded for free as source code from the
Repository. Yes, you have to build them. However, there are build
instructions included in the packages. Quick and dirty:

- For utils2_ak: Just decompress the package file (utils2_ak.gz) using

gunzip and execute the resulting shell archive file (utils2_ak) using the

bash shell: bash ./utils2_ak. It will unpack itself and offer to let you

read the README.1st and BUILDIT text files. Building utils2_ak on Linux is

trivial. Just run: ./make and it will build itself. The building

instructions are for making changes to the "makefile" to support other

operating systems, but I maintain it on Linux so the default makefile will

work out-of-the-box. If you want to edit the file Makefile and change the

entry for the tag INSTALLDIR from /usr/local/bin to wherever you want to

install the executables and run: make install

- For sqlcmd: Decompress the sqlcmd-88.00.tgz file using gunzip, it

will leave a file with the same name but with a .tar extension. Then you

unpack the tar file with: tar xvf ./sqlcmd-88.00.tar. Then cd into the

directory it will create and execute the "configure" script that is there.

It will configure the make files for you after detecting what versions of

tools and libraries you have installed. They just type "make" to build the

tool. If you want to install the executables type: make install and the

executables will be installed in $INFORMIXDIR/bin for you. The file

INSTALL has instructions for changing this location.

- For myonpload: Extract the myonpload.zip file with "unzip

myonpload". There is a file myonpload.README with build instructions but

it is simple (I haven't built this myself in many years). There is only

one source file myonpload.ec which you should be able to compile with:

gcc -o myonpload myonpload.ec and a single SQL script, which you have to

execute against the HPLoader database.
