Error when trying to setTitle on new DB - xpages

Question

I'm working on an Archiving Application with this code in it:
var arcName:String = "Archives/" + aDBName + "-Backup-" + toDay + "-" + thisTime.slice(0,5);
var server:String = appDB.getServer();
var arcDB:NotesDatabase = appDB.createCopy(server, arcName);
arcDB.setTitle("This is a Test");
but it fails at the arcDB.setTitle - the new copy of the Database is created so there is no issue to that point.
This is from the IBM Knowledge base:
var db2:NotesDatabase = db.createCopy(null, "names2");
db2.setTitle("Copy of names");
I can't see the difference between these two pieces of code.
Am I missing something?

Answer 1

Usually when something doesn't work with XPages that relates to database or design objects the first thing I check is the Maximum Internet Name and password Access https://stackoverflow.com/a/23045860/1187943
Or change so I do the work using sessionAsSigner or sessionAsSignerWithFullAccess

Answer 2

If you don't care about the effectiveUser's access to the source database, their permissions to make a copy, and their access rights to create a NotesDatabase on the target Domino server, I'd absolutely second Fredrik's suggestion to use sessionAsSigner/WithFullAccess.
Additionally, I find it's best practice to use try/catches (helps with troubleshooting and errorHandling), object testing (.isOpen() when accessing a NotesDatabase), and returning an Object that can be read by the calling function.
Here's some example code that might help:
var copyNotesDatabase = function(dbName) {
var isSuccessful = true;
var responseMessage = "";
try {
//set appDB using dbName from function arguments
var appDB = session.getDatabase(session.getServerName(),dbName);
//var appDB = sessionAsSigner.getDatabase(session.getServerName(),"sourceDb.nsf");
//var appDB = sessionAsSignerWithFullAccess.getDatabase(session.getServerName(),"sourceDb.nsf");
if(appDB.isOpen()) {
var arcName:String = "Archives/" + aDBName + "-Backup-" + toDay + "-" + thisTime.slice(0,5);
var server:String = appDB.getServer();
//arcDB will be created based on appDB permissions, ie effectiveUser, or sessionAsSigner, etc.
var arcDB:NotesDatabase = appDB.createCopy(server, arcName);
if(arcDB.isOpen()) {
arcDB.setTitle("This is a Test");
responseMessage = "Successfully copied NotesDatabase!"
} else {
isSuccessful = false;
responseMessage = "Unable to open copied NotesDatabase.";
}
} else {
isSuccessful = false;
responseMessage = "Unable to open source NotesDatabase.";
}
} catch(e) {
print("Error from SSJS: " + e);
isSuccessful = false;
responseMessage = e;
}
return { status : isSuccessful, message : responseMessage };
}
With this function, you could do something like this:
function makeCopy(appName) {
var fObj = copyNotesDatabase(appName);
if(fObj.status) {
return "Successfully copied " + appName;
} else {
return fObj.message;
}
}
... at the very least, using a try/catch and returning your error will at least tell you why your current code isn't working. Hope this helps!
