README for the HP Neoview ODBC Drivers for UNIX (R2.4)

Using a Third Party Driver Manager

• If you are using an external driver manager, you must point to libhpodbc_drvr and not to

libhpodbc. (Use libhpodbc_drvr64 if you are using 64-bit versions of external driver

managers.)

• The driver (libhpodbc_drvr.so) has been verified with iODBC and unixODBC driver

managers.

• These driver managers, as well as documentation, can be found at these Web sites:

http://www.iodbc.org/

http://www.unixodbc.org/

• The three environment variables that control tracing are:

— HPODBC_TRACE_LEVEL — sets trace level (ERROR, WARNING, CONFIG, INFO,

or DEBUG)

— HPODBC_TRACEFILE_NAME — specifies the name of the log file

— HPODBC_TRACEFILE_SIZE — specifies the maximum files size of the log files

• For information on the necessary data source configuration options, you will need to add

to the respective configuration files (for example, to odbc.ini). For more information, see the

Neoview ODBC Drivers Manual at http://www.hp.com/go/neoviewdocs.

Running the Sample Program

NOTE: The examples after each step assume that you have default installation directories.

If you have a previous version of the hpodbc driver installed, you need to re-link your existing

application to ensure that you pick up the correct version of the driver. If you are unsure of the

version, check the version of your application with this command:

ldd <object file>

1. Move to the directory where you installed the sample program:

cd /etc/hpodbc/sample

2. Compile the sample program.

All drivers, other than the 64-bit driver for HP-UX(IA-64), x86_64 Linux driver, and IA-64

Linux are 32-bit drivers; therefore, applications need to be compiled accordingly.

Compile CommandClient OS

g++ connect_test.cpp -L/usr/lib -I/usr/include/hpodbc -lhpodbc \

-o connect_test

NOTE: This Linux driver is a 32-bit driver. If you are using an x86-64 machine, you need to

explicitly compile your application as a 32-bit application. For example:

g++ connect_test.cpp -m32 -L/usr/lib \

-I/usr/include/hpodbc -lhpodbc -o connect_test

x86 Linux

g++ connect_test.cpp -L/usr/lib -I/usr/include/hpodbc \

-lhpodbc64 -o connect_test

x86_64 Linux
