* README for C++ Samples on Linux
*
* The <install_path>/sqllib/samples/cpp directory contains this README file
* where <install_path> is the location of DB2 9.7 on your hard drive.
* The default location for <install_path> is $HOME.
* This README describes how to build and run cpp sample code for DB2 9.7.
*
* The DB2 9.7 sample code for C++ is located in the following directory:
* <install_path>/sqllib/samples/cpp
*
* It is recommended that you copy the files from this directory to your
* working directory prior to building the sample programs. The sample
* programs directory is typically read-only on most platforms and some
* samples generate temporary files.
*
* WARNING: Some of these samples may change your database or database manager
* configuration. Execute the samples against a 'test' database only,
* such as the DB2 SAMPLE database.
*
* NOTE: These samples are tested on sample database created using db2sampl.
*
******************************************************************************
*
* Prepare your DB2 sample development environment
*
* 1) Copy the files from sqllib/samples/cpp to your working directory and
* ensure that directory has write permission.
*
* 2) Start the Database Manager with the following command:
* db2start
*
* 3) Create the sample database with the following command:
* db2sampl
*
* 4) Connect to the database with the following command:
* db2 connect to sample
*
* 5) To build Stored Procedures and User Defined Functions, ensure
* that you have write permission on the <install_path>/sqllib/function
* directory.
*
* 6) cd to the directory containing the files copied in Step 1.
*
******************************************************************************
*
* Building DB2 Samples
*
* There are two ways to build DB2 samples: using a make utility or using the
* build files that are included with the DB2 sample programs.
* o To build samples using the make utility see 'BUILDING SAMPLES USING
* make UTILITY'.
* o To build samples using the build files or when you do not have a
* compatible make utility see 'BUILDING SAMPLES USING BUILD FILES'.
*
******************************************************************************
*
* *** BUILDING SAMPLES USING nmake UTILITY ***
*
* If you have a compatible make utility on your system, you can use the
* makefile provided. Such a make utility may be provided by another language
* compiler. Modify the PATH variable to include the directory containing the
* make utility.
*
* Depending on your environment, the makefile might have to be modified.
* For more details refer to the 'VARIABLES' section in the makefile.
*
* Execute the appropriate 'make' command in your working directory:
* o make <program name> - builds the sample identified by <program
* name>. Do not include the file extension for
* the program name. E.g. make DbAuth
* For any dependencies refer to the individual
* sample.
* o make srv - builds only samples that can be run on the
* server, including routines (stored procedures
* and User Defined Functions).
* o make rtn - builds only routines.
* o make call_rtn - builds only client programs that call
* routines.
* o make client_run - builds only programs that run completely on
* the client (not ones that call routines).
* o make all_client - builds all client samples (all programs in
* the 'call_rtn' and 'client_run' categories).
* o make all - builds all supplied sample programs
*
* NOTE: Create a database with name SAMPLE2 before running 'make all' as
* some of the samples require two databases. Create second database
* with the following commands:
* db2 connect reset -- To disconnect from sample database.
* db2 create database sample2 -- Create second database.
* db2 connect to sample -- Reconnect to sample database.
*
******************************************************************************
*
* *** BUILDING SAMPLES USING BUILD FILES ***
*
* As an alternative to the makefile, the build files included with the DB2
* samples can be used to build the CPP sample programs.
*
* Building Standalone Samples:
* o bldapp <prog_name>
* <prog_name> - the name of the sample program without
* any extension.
* For any additional dependencies refer to the individual sample.
*
* Building and Executing Stored Procedures:
* o Build stored procedure server and copy the resulting binary file to
* the sqllib/function directory with the following command:
* bldrtn <prog_name>
* <prog_name> - Name of the sample program without any
* extension.
* o Catalog stored procedures with the following command:
* spcat
* o Build stored procedure client with the following command:
* bldapp <prog_name>
* <prog_name> - Name of the sample program without any
* extension.
*
* Building and Executing User Defined Functions:
* o Build UDF server and copy the resulting binary file to the
* sqllib/function directory with the following command:
* bldrtn <prog_name>
* <prog_name> - Name of the sample program without any
* extension.
* o Catalog User Defined Functions with the following command:
* udfcat
* o Build UDF client with the following command:
* bldapp <prog_name>
* <prog_name> - Name of the sample program without any
* extension.
*

* The following are the common files for C++ samples. For more
* information on these files, refer to the program source files.

******************************************************************************
*
* Samples Design
*
* Most of the C++ sample programs are organized to reflect an object-based
* design of the distinct levels of DB2. A sample's level is indicated by a
* two character identifier at the beginning of the sample name. These levels
* show a hierarchical structure: an application can access different
* instances, an instance can have different databases, etc. Here are the DB2
* levels demonstated by the C++ samples:
*
* Identifier DB2 Level
*
* cl Client Level.
* in Instance Level.
* db Database Level.
* ts Tablespace Level.
* tb Table Level.
* dt Data Type Level.
*
******************************************************************************
*
* Other Samples
*
* Besides the samples organized in the DB2 Level design, other samples show
* specific kinds of application methods:
*
* Identifier Application Method
*
* fn SQL functions.
* sp Stored Procedures.
* ud User Defined Functions.
