I have small method to get connection to Lotus Domino database:
Session session = NotesFactory.createSession(host, user, password);
Database db = session.getDatabase(serverName, dbName);
So now I need to get some info from db with search() method. And as I know I need to use some "search formula". For example form="formUnit" & #IsUnavailable($Conflict)
What type of script is this, where I can find inforamtion about this?
It's Notes/Domino Formula language. More info here:
http://publib.boulder.ibm.com/infocenter/domhelp/v8r0/index.jsp?topic=%2Fcom.ibm.designer.domino.main.doc%2FH_NOTES_FORMULA_LANGUAGE.html
You cannot use #Commands in db.search() and also not all #Formulas. Check also db.FTSearch() which is much faster in big databases but the db needs to be full text indexed.

I need to write to a non-VSAM dataset in the mainframe. I know that we need to use the ZFile library to do it and I found how to do it here
I am running my Java batch job in the WebSphere Liberty on zOS. How do I specify the dataset? Can I directly give the DataSet a name like this?
dsnFile = new ZFile("X.Y.Z", "wb,type=record,noseek");
I am able to write it to a text file on the server itself using Java's File Writers but I don't know how to access a mvs dataset.
I am relatively new to the world of zOS and mainframe.
It sounds like you might be asking more generally how to use the ZFile API on WebSphere Liberty on z/OS.
Have you tried something like:
String pdsName = ZFile.getSlashSlashQuotedDSN("X.Y.Z");
ZFile zfile = new ZFile(pdsName , ...options...)
As far as batch-specific use cases, you might obviously have to differentiate between writing to a new file that's created for the first time on an original execution, as opposed to appending to an already-existing one on a restart.
You also might find some useful snipopets in this doctorbatch.io repo, along with the original link you posted.
For reference, I'll copy/paste from the ZFile Javadoc:
ZFile dd = new ZFile("//DD:MYDD", "r");
Opens the DD namee MYDD for reading
ZFile dsn = new ZFile("//'SYS1.HELP(ACCOUNT)'", "rt");
Opens the member ACCOUNT from the PDS SYS1.HELP for reading text records
ZFile dsn = new ZFile("//SEQ", "wb,type=record,recfm=fb,lrecl=80,noseek");
Opens the data set {MVS_USER}.SEQ for sequential binary writing. Note that ",noseek" should be specified with "type=record" if access is sequential, since performance is greatly improved.
One final note, another couple useful ZFile helper methods are: bpxwdyn() and getFullyQualifiedDSN().
I'm working in a legacy app for the moment, upgrading Access 2003 to link to SQL Server tables (2008 R2 or later). With tables linked by code, I can insert, but not update or delete. I've tried everything on the web, no dice. Details below.
Being terse so not tl;dr.
Tables first created using upsizing wizard. In use, app has to connect to different ones in same schema, so can't just set and forget. Can't do local DSN's, many installs, though DSN file is possible. But problems there too, DSN not found. Details later.
Before the rest: Soon I'm further updating this app to Access 2016 or so. If this is different enough / easier there, I'll wait a few days. Maybe someone could suggest the best refsite for that.
* problem details follow *
Using a DSN and the UI to link a table, I get an editable table. Hurray.
But when I use the code below (found on every refsite), link is made but only selecting and inserting work. Everything else fails fails fails, no matter what.
Public Function LinkToSqlTable(sqlInstance As String, sqlDb As String,
sqlTableName As String, localTableName As String)
Dim linked As New TableDef
' ***factored-out functionality, known to work: reader can ignore*** '
DeleteTable localTableName
' connection-string steps, placeholders replaced by args '
Dim sCnx As String
sCnx = "ODBC;Driver=SQL Server;Server=_instance_;" & _
"Database=_db_;Integrated Security=SSPI"
sCnx = Replace(sCnx, "_instance_", sqlInstance)
sCnx = Replace(sCnx, "_db_", sqlDb)
' linked-table steps '
Set linked = CurrentDb.CreateTableDef(localTableName)
linked.Connect = sCnx
linked.SourceTableName = sqlTableName
CurrentDb.TableDefs.Append linked
' ui '
RefreshDatabaseWindow
End Function
* ID column or permissions? *
I thought the problem was lack of identity column originally, I added one, but no change. At least now I have a PK field like I should. ;-)
When I manually link table, UI demands to know the ID column. So could it still be it? Fine, but how do I set that in code? Searches revealed nothing.
I assume then it's permissions as sites etc. say. I also took all the steps I could think of to fix that. No dice.
* things I've tried *
Aside from the ID-column stuff I said before, these things (not in order):
Since DSN saved as a file, tried using it as exampled, in cnx string. Fail.
Used DSN contents, carefully winnowed & translated, in cnx string. Fail.
Used connection string from the table that I had connected manually with DSN. Fail.
Changed driver in cnx string across all major options, even omitted it. Fail.
Changed security in cnx to Integrated Security=SSPI and other options, and omitted entirely. Fail.
I added my actual local user as exampled, with and without password. Fail.
(Previous few options tried across earlier options, though not 100% coverage.)
In SQL Server, using SSMS, I tried security power:
Added SQS-authentication login to the instance
Matching user to the default db seen here
Gave that login-user read and write permissions in db here (plus others, sometimes)
Added matching id & pw to the cnx string. Fail.
I tried setting up this db in SQS to have let-everyone-do-everything "security" temporarily. Fail.
This, that, and the other thing. Everything fail!!
So a permissions issue? Some way to use DSN file after all? Mismatched permission settings in my cnx string? Boneheaded oversight? Something else that I've missed? I'm pretty good at both SQL Server and Access, but only at a basic level in their security stuff and connection strings are the devil.
* retrieved table properties *
Just in case they help, I retrieved these (after objects added to TableDefs collection).
** This one, done in UI and with DSN and this-is-ID-field, worked with editing: **

* my plea *
So..... Please someone help me out. I don't like feeling stupid like this, and regrettably I need to do this instead of replacing it with .NET code or similar.
Thanks, anyone who can...

Alas, I am able to answer my own question.
edited a little since first posted in reply to HansUp's comments
I had added an identity column to the table that I couldn't edit. However, I had not set it up as a primary key. It turns out that using identity doesn't make something a primary key automatically.
But the latter, making it primary key using either of the 2 possible DDL syntaxes, is crucial. Since I thought I had dealt with the no edits without unique key problem, I focused on permissions.
All of the permissions things here, then, are just a sideshow.
The upshot of this is to be sure to add an identity column and make it a primary key if for some reason your original table schema didn't have that.
If I have the time, I will be trimming the question to reflect what I've discovered.
I'm creating an in-house application and have always hardcoded the database connection string. However, this time I want to do something different and give the users the ability to enter the information from the application.
I figured out that I can store the variables in the Application Settings and call them from code, but I can't figure out how to call them within the connection string.
Here's the code:
Dim dbConn As New MySqlConnection
dbConn.ConnectionString = "Server=172.43.96.271;Port=3306;Uid=someone;
Password=theirpassword;Database=thedb"
Hope I explained myself well?
You can simply concatenate the string together, or better yet, use the String.Format method:
dbConn.ConnectionString = String.Format("Server={0};Port={1};Uid={2};Password={3};Database={4}", My.Settings.Server, My.Settings.Port, My.Settings.Uid, My.Settings.Database)
If you were using MS SQL, I'd recommend using the SqlConnectionStringBuilder class to do it, but since you're using MySql, it doesn't really apply. You may be able to use it anyway, though.
You would have to use User Settings for this.
And, if you want the users to input the separate parts of the connection string (Server, Post, Username, Password and DB), you would have to create a settings entry for each of those, and then construct the connection string from those values.
Here's a good article for this: User Settings Applied
I'm using an application called Logi info. it requires a connection string to my oracle database. the connection works fine but in order to configure the connection to recive ref cursors from the database, I apparently need to add PLSQLRSet=1 to the end of the string. when I do that I recieve an error "invalid connection string"
Here is my connection string without plsqlrset=1
Data Source=SID; User Id=username; Password=password;
My concern is that PLSQLRSet=1 might be .NET paramater only. Can anyone shed some light on the issue.
Thanks
It appears that the PLSQLRset option is a feature of the OraOLEDB provider (per http://download.oracle.com/docs/cd/B10501_01/win.920/a95498/using.htm).
Therefore I would guess that you have to add Provider=OraOLEDB.Oracle to the connect string -- as shown in the screenshot on the page you linked to -- in order to use this option.
we've got a real confusing problem. We're trying to test an SQL Bulk Load using a little app we've written that passes in the datafile XML, the schema, and the SQL database connection string.
It's a very straight-forward app, here's the main part of the code:
SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class objBL = new SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class();
objBL.ConnectionString = "provider=sqloledb;Data Source=SERVER\\SERVER; Database=Main;User Id=Username;Password=password;";
objBL.BulkLoad = true;
objBL.CheckConstraints = true;
objBL.ErrorLogFile = "error.xml";
objBL.KeepIdentity = false;
objBL.Execute("schema.xml", "data.xml");
As you can see, it's very simple but we're getting the following error from the library we're passing this stuff to: Interop.SQLXMLBULKLOADLib.dll.
The message reads:
Failure: Attempted to read or write protected memory. This is often an indication that other memory has been corrupted
We have no idea what's causing it or what it even means.
Before this we first had an error because SQLXML4.0 wasn't installed, so that was easy to fix. Then there was an error because it couldn't connect to the database (wrong connection string) - fixed. Now there's this and we are just baffled.
Thanks for any help. We're really scratching our heads!
I am not familiar with this particular utility (Interop.SQLXMLBULKLOADLib.dll), but have you checked that your XML validates to its schema .xsd file? Perhaps the dll could have issues with loading the xml data file into memory structures if it is invalid?
I try to understand your problem ,but i have more doubt in that,
If u have time try access the below link ,i think it will definitely useful for you

I know I did something that raised this error message once, but (as often happens) the problem ended up having nothing to do with the error message. Not much help, alas.
Some troubleshooting ideas: try to determine the actual SQL command being generated and submitted by the application to SQL Server (SQL Profiler should help here), and run it as "close" to the database as possible--from within SSMS, using SQLCMD, direct BCP call, whatever is appropriate. Detailing all tests you make and the results you get may help.
