### This script prepares a secondary site for the DR setup
### This script should be executed in the SECONDARY Weblogic Administration server node. BEFORE executing this script
### the fmwadb_dr_rsync_only_prim.sh script should have been executed in the primary system so that a copy of the primary domain exists in the local
##  FSS mount
### Usage:
###
###      ./fmwadb_dr_stby.sh [WALLET_DIR] [WALLET_PASSWORD] [FSS_MOUNT]
### Where:
###	WALLET_DIR:
###					This is the directory for an unzipped ADB wallet.
###					This directory should contain at least a tnsnames.ora, keystore.jks and truststore.jks files. 
###	WALLET_PASSWORD:		
###					This is the password provided when the wallet was downloaded from the ADB OCI UI.
###					If the wallet is the initial one created by WLS/SOA/FMW during provisioning it can be obtained
###					with the following commands:
###					SOA	python /opt/scripts/atp_db_util.py generate-atp-wallet-password
###					WLS	python3 /opt/scripts/atp_db_util.py generate-atp-wallet-password
###					
###	FSS_MOUNT:
###					This is the OCI File Storage Mounted directory that will be used to stage the WLS domain configuration
