** SOURCE FILE NAME: admincmd_onlinebackup.c
**
** SAMPLE: How to perform online backup using ADMIN_CMD() routines.
**
** This sample should be run using the following steps:
**
** 1.Create and populate the "sample" database with the following command:
** db2sampl
**
** 2.Set the DB CFG parameter LOGARCHMETH1 LOGRETAIN
**
** 3.Set the DB CFG parameter LOGARCHMETH2 OFF
**
** 4.Do an offline BACKUP of SAMPLE database
**
** 5.Compile the program with the following command:
** bldapp admincmd_onlinebackup
**
** 6.Run this sample with the following command:
** admincmd_onlinebackup <path for backup>
** The path being given for backup should be an absolute path.
**
** Note: User needs either SYSADM, SYSCTRL or SYSMAINT authorization to set
** the DB CFG parameters & for backing up the database.
**
** CLI FUNCTIONS USED:
** SQLAllocHandle -- Allocate Handle
** SQLBindCol -- Bind a Column to an Application Variable or
** LOB locator
** SQLBindParameter -- Bind a Parameter Marker to a Buffer or
** LOB locator
** SQLExecute -- Execute a Statement
** SQLFetch -- Fetch Next Row
** SQLFreeHandle -- Free Handle Resources
** SQLPrepare -- Prepare a Statement
**
