mongodb - Minimum Privileges required for Mongo lock and unlock -


we need have user minimal privileges able lock mongo instance, using db.fsynclock() , db.unlock(), ensure can take consistent snapshots of disk images. have following role created:

{     "role" : "local_lock",     "db" : "admin",     "isbuiltin" : false,     "roles" : [ ],     "inheritedroles" : [ ],     "privileges" : [         {             "resource" : {                 "cluster" : true             },             "actions" : [                 "logrotate",                 "resync",                 "unlock"             ]         }     ],     "inheritedprivileges" : [         {             "resource" : {                 "cluster" : true             },             "actions" : [                 "logrotate",                 "resync",                 "unlock"             ]         }     ] }

but when use user attempt lock receive following:

> db.fsynclock() {     "ok" : 0,     "errmsg" : "not authorized on admin execute command { fsync: 1.0, lock: true }",     "code" : 13,     "codename" : "unauthorized" } >

what other permissions required? mongo versions follows:

mongodb shell version v3.4.7 mongodb server version: 3.4.7

well, limiting user tight may not idea , potentially he/she may not perform action @ all.

however, try granting fsync , unlock permissions account. see fsync , unlock actions in documentation.

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 <...
