Creating a Customized Version of DataLoader/MX

DataLoader/MX Reference Manual—543544-001

Example

DataLoader/MX installation directory can be specified by setting the environment

variable DL_INSTALL_DIR to point to the installation directory. For example:

$ export DL_INSTALL_DIR="/usr/opt/dataloader"

You can set the environment variable DL_COMP_OPTION to specify options that

need to be passed to the c89 or ecobol language compiler during source

compilation. For example:

$ export DL_COMP_OPTION="-Wsql=CHAR_AS_ARRAY"

If you have multiple source files containing various exit routines, you must

language compile them individually, link them together into a library, and give the

library file as input to build.sh.

Example

To create your own version of DataLoader/MX:

1. Create the source code for the user exits you want to replace.

Make a copy of the source for the default exits, remove the code for the exits you

do not need to replace, and modify the code for the ones you want to change. The

source files that contain the default user exits are included with the DataLoader/MX

package:

•

sexits.c for C code

•

sexitscb.cob for COBOL code

2. Run the build script. For example:

$ /usr/tandem/dataloader/build.sh mysource.c mydataload MX

In this example:

/usr/tandem/dataloader

is the directory in which DataLoader/MX was installed.

mysource.c

is the name of the modified source file.

mydataload

is the name of the new object file to be created.

specifies that there is embedded sql in the input source file, and SQL/MX SQL

compilation is required.
