You're calling glob in scalar context (via <...>). glob acts as an iterator, returning undef once all the results have been returned. For example, 

$ perl -wle'print scalar <{a,b,c}> for 1..6'
a
b
c
Use of uninitialized value in print at -e line 1.

a
b

Or something closer to what you have, 

$ perl -wle'print scalar < $_ > for 1..6'
1
Use of uninitialized value in print at -e line 1.

3
Use of uninitialized value in print at -e line 1.

5
Use of uninitialized value in print at -e line 1.

What are you trying to do with <...>? I think you might simply want 

$dbLogLst{$dbName} = "$ENV{'DIAG'}/$dbName/log/alert_$dbName.log";
