Code:
awk '{ split($0, arr, "=" ); if ( match($0, "Host") ) { host[i++]=substr(arr[2], 2, length(arr[2]) - 2) } else if ( match($0, "SID") ) { db[j++]=substr(arr[3], 2, length(arr[3]) - 2); } }' filename

Code:
awk '{ split($0, arr, "=" ); if ( match($0, "Host") ) { host[i++]=substr(arr[2], 2, length(arr[2]) - 2) } else if ( match($0, "SID") ) { db[j++]=substr(arr[3], 2, length(arr[3]) - 2); } }END{ for ( x=0; x<i; x++ ) { print host[x] } for ( x=0; x<j; x++ ) { print db[x] } }' filename
