############################################################################

############################################################################
# This is a common funtion library that can be included in a script
# via . dg_common.ksh this will allow access to the functions
# db_conn - this provides the connectivity to the database
############################################################################

############################################################
# DataGuard Functions
# Use the following functions to install and maintain dataguard
############################################################

############################################################
# dg_init             - Initialize variables or other functions
# dg_dbrd             - Shows a dashboard
# dg_inst_order       - Displays order of install of scripts
# dg_asm_dgs          - Shows the ASM diskgroups to show the space avail and diskgroups that exist
# dg_cr_log           - create dbfs install log
# dg_pre_inst         - Check for OS params
# dg_srv_stat         - Status of all services configured on the DB
# dg_stop_allsvc      - Stop all services configured on the DB
# dg_start_allsvc     - Start all services configured on the DB
#

# dbfs_chk_db_usr     -
# dbfs_cr_tblspc      - Create DBFS tablespace
# dbfs_drp_tblspc     - Drop DBFS tablespace
# dbfs_cr_usr         - Create DBFS user
# dbfs_drp_usr        - Drop DBFS user
# dbfs_cr_objs        - Create DBFS objects
# dbfs_cr_mnt_pnt     - Create the DBFS mountpoint
# dbfs_test_access    - Test access to the DBFS directories
# dbfs_inst_qa        - QA the install
