postgresql - Error connection pgadmin 4 -


i add server , there error image

i use pgadmin4

how can fix this?

firstly, check if server listening. use following command on server: 

netstat -nlt|grep :5432

if it's ok, ssh (or whatever method use access server) server , view file:

/etc/postgresql/9.1/main/postgresql.conf

find line start with:

listen_addresses=

if value after "=" 'localhost', means cannot connect outside. able so, change to:

listen_addresses='*'

now able connect anywhere, outside server itself. and, don't forget restart dbms , check if works.

ah. 1 more thing, may need give user access rights database well.

open file:

/etc/postgresql/9.1/main/pg_hba.conf

and add:

host all * md5

you need restart dbms fire changes.

p/s: should enable ssl.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
