Prepare the Installer for OHF DMA Install

-	Prepare the Installer
	Extract the contents of the OHF media pack to any VM instance (which can connect to ADW).
	Make a new directory OHF installation home <OHF_INSTALL_HOME> .
	Copy the OHF media pack to <OHF_INSTALL_HOME>/.
	Unzip the OHF_822_Linux-x64.zip file where you want to launch the installer using the following command: unzip -a OHF_822_Linux-x64.zip
	Open the Disk1/stage/Components/oracle.hsgbu.hc.dma.infa/8.2.2.0.0/1/DataFiles/Expanded/filegroup1 folder. There is a zip file in the folder: dma_infa_master_install.zip
	Copy the dma_infa_master_install.zip file to OHF installation home. cp dma_infa_master_install.zip <OHF_INSTALL_HOME>/dma_infa_master_install
	Unzip dma_infa_master_install.zip in the <OHF_INSTALL_HOME>/dma_infa_master_install folder. unzip -a dma_infa_master_install.zip
	Change the protection on files as follows: chmod 755 *
	Update user parameters with the OHF pre-created schema in the <OHF_INSTALL_HOME>/dma_infa_master_install/ADW_INFA_SETENV_CREATE.ksh script. Table 10-1 Parameters Parameter Description ORAHOME Oracle home directory BASEDIR Installation home directory OHFCRDFILE OHF ADW wallet credential file location OHFDBSRVNM OHF data model ADW service name HDIUSR HDI schema name HDMUSR HDM schema name HCDUSR HCD schema name CDMUSR CDM schema name ENTUSR ENT schema name WILHMCUSR WIL_HMC schema name ATHMCUSR AT_HMC schema name or HCD_HMC schema name. Both are the same. The remaining parameters have fixed values and Oracle recommends that you do not change these values. Schema passwords are prompted while running the script.
	Before running the installer, make sure that the ORACLE_HOME, PATH and LD_LIBRARY_PATH environment variables are setup in your session. For example: export ORACLE_HOME=/u01/oracle/instantclient_19_9 export LD_LIBRARY_PATH=$ORACLE_HOME/lib export PATH=$PATH:$ORACLE_HOME/bin
