I have created cube in PSW and published it over BI server. Using this cube I have created jPivot view (slice & dice).
When I try to expand the view it gives me "Resultset overflow occured" message. Logs are not showing any error.
I am using PSW CE -8.1 and Pentaho Server CE 8.1
Total records in fact table is 25 million
Below is done to optimise the performance:
Indexes are added in dimensions and fact tables
Pentaho query time out increased
file name - pentahoobjects.spring.xml
Tomcat time out increased
server.xml -> change connectiontimeout to 0
Below mondrian.properties are changed (mondrian/mondrian.properties)
mondrian.result.limit=0
mondrian.olap.case.sensitive=false
mondrian.native.crossjoin.enable=true
mondrian.native.ExpandNonNative=false
Please suggest what is wrong or any other property needs to be optimised.
Thanks,

Ok, I got an weird problem: I got two server-side api, one is to select data from A table; the Other one is to Insert new record to B table with part of the data and PK from first one. They should not have any problem to each other with the Usual actions.
Somehow, I detected someone which called my select and insert function at less than 0.005 sec on my SQL monitor, which caused S-IX deadlock. So I searched the Internet and found an solution that told me to enable the Snapshot isolation. But I tried it on my test DB(which its total size is about 223MB), that Alter Database command does not show any sight of finishing after 1 hour execution, so this is intolerable to execute it on the Production DB with such long Downtime(Which its data size is bigger than the Test one).
So my question is: Does anyone know the Other way to solve the S-IX deadlock?(Without lower the Throughput.)
P.S.: My DB is SQL Server 2008
I'm simply doing a select * from one of my tables. It is a daily table containing yesterday's data and was working fine yesterday and earlier today. It is suddenly returning "Error: Unexpected. Please try again."
Are there any production issues currently? The job id for one of these failed queries is job_Tj_vZhAqfZH9jpW52M8IUld4XKE
A configuration change this morning caused a problem querying from tables that had been written to via streaming. The issue should be fixed now. Please ping this thread if you continue to see problems.
I'm working with a moderately sized database of about 60,000 records. I am working on building a mobile application which will be able to check out a single table into a compact .sdf on for viewing and altering on the device, then allow the user to sync their changes back up with the main server and receive any new information.
I have set it up with the Sync Framework using a WCF Service Library. When setting up the connection for some reason the database won't let me check "Use SQL Server Change Tracking" and throws up the error:
"'Unable to initialize the client database, because the schema for table 'Inventory' could >not be retrieved by the GetSchema() method of DbServerSyncProvider. Make sure that you can >establish a connection to the client database and that either the >SelectIncrementalInsertsCommand property or the SelectIncrementalUpdatesCommand property of >the SyncAdapter is specified correctly."
So I leave it unchecked and set it to use some already created columns "AddDateTime" and "LastEditTime" it seems to work okay, and after a massive amount of tweaking I have it partially working. The changes on the device sync up perfectly with the database, updates, deletes, all get applied. However, changes on the server side...never get updated. I've made sure everything is set up right with the bidirectional setup so that shouldn't be the problem. And, I let it sit overnight so the database received ~500 new records, this morning it actually synced the latest 24 entries to the database...out of 500 new. So that should be further proof that it's able to receive information from the server, but for all useful purposes, it's not.
I've tried pretty much everything and I'm honestly getting close to losing it. If anyone has any ideas they can throw out I can chase after I would be most grateful.
I'm not sure if I just need to go back and figure out why I can't do it with the "SQL Server Change Tracking". Or if there is a simple explanation for why it's not actually syncing 99% of the changes on the server back to the client.
Also, the server database table schema can't be altered as a lot of other services use it. But the compact database can be whatever the heck in needs to be to just store the table and sync properly in both directions.
Thank you!!
Quick Overview:
Using WCF and syncing without SQL Server Change Tracking (Fully enabled on server and database)
Syncing changes from client to server works perfectly
Syncing from server back to the client not so much: out of 500 new entries overnight, on a sync it downloaded 24.
EDIT: JuneT got me thinking about the time and their anchors. When I synced this morning it pulled 54 of about 300 new added records. I went in to the line (there are about 60 or so columns, so I removed them for readability, this is kind of a joke)
this.SelectIncrementalUpdatesCommand.CommandText = #"SELECT [Value], [Value], [Value] FROM >TABLE WHERE ([LastEditDate] > #sync_last_received_anchor AND [LastEditDate] <= >#sync_new_received_anchor AND [AddDateTime] <= #sync_last_received_anchor)";
And replaced #sync_last_received_anchor with two DIFFERENT times. Upon syncing it now returns the rows trapped between those two and took out the middle one giving me:
this.SelectIncrementalUpdatesCommand.CommandText = #"SELECT[Value], [Value], [Value] FROM >TABLE WHERE ([LastEditDate] > '2012-06-13 01:03:07.470' AND [AddDateTime] <= '2012-06-14 >08:54:27.727')"; (NOTE: The second date is just the current time now)
Though it returned a few hundred more rows than initially planned (set the date gap for 600, it returned just over 800). It does in fact sync the client up with the the new server changes.
Can anyone explain why I can't use #sync_last_received_anchor and what I should be looking for. I suppose I could always add box that allows the user to select the date to begin updating from? Or maybe add some sort of xml file to store the sync date that would be updated anytime a sync was -successfully- completed?
Thanks!
EDIT:
Ran the SQL profiler on it...the date (#sync_last_received_anchor) is getting set to 8 hours ahead of whatever time it really is. I have no idea how or why it's doing this, but that would definitely make sense.
Turns out the anchors are collected like this:
this.SelectNewAnchorCommand.CommandText = "Select #sync_new_received_anchor = GETUTCDATE()";
That UTC date is what was causing the 8 hours gap. To fix it either change it to GETDATE(), or convert your columns to UTC time in the WHERE clause of the commands.
After spending many hours with many cups of coffee, I've figured out how to solve this error of mine. While I was running the code on desktop testing area, everything seemed to be working perfectly; however the same code and webservice on target device gave this error repeatedly. Then, suddenly, the "dbo_" prefixes on compact database table names started looking interesting, like they were trying to tell me something really important. So, I've listened...
Configuration.SyncTables.Add("Products);
on ClientSyncAgent.cs should be changed to
Configuration.SyncTables.Add("dbo_Products");

I have some ssis packages & a cube to process in my job scheduled.
When I process the cube in visual studio, its working fine even I tried it manually in analysis services of sql, it works there too.
But my job fails saying the step of process cube.
Here is a part of the error message:
A duplicate attribute key has been found when processing: Table: 'dbo_Customer', Column: 'Updated_By', Value: '
Please help me.
I had done it at my own , One of my Excel templates have no value assigned in "updated by" column & so the database have no value in it. It coming as blank. so creating issue while processing cube.
you should read about the UnknowMember on the dimension. It is common to come across situations where
you have a Fact not related to a dimension.
Basically what it does is when facing this situation, instead of breaking the refresh it will substitute the missing value by whatever you have configured on the UnknowMemberName (N/A for example)
I started using the system with a pre-made file called DB2.SQL. I am using this because it is what the tutorial said to use. I then edited this file and replaced the contents with my own code:
CREATE DATABASE BANKDB13 BUFFERPOOL BP0;
When I try to execute a SQL it though, I get this error:
DSNE377A INPUT DATA SET RECFM MUST BE F OR FB WTIH LRECL 80
What does this error mean and how do I correct it on the file?
I am running it with Vista TN3270 on Windows 7 over TSO, in SPUFI mode.
What I've tried so far:
When I start editing the file, I have a screen to change the defualts, and I have changed the RECORD FORMAT to F and FB as well as setting the RECORD LENGTH to 80 with no success.
EDIT:
I resolved the problem by deleting the DB2.SQL file and recreating it, and also making sure that the sizes I gave for the files were consistent with each other.
What SQL are you trying to execute on it?
The error means that the Record Format in the input data set must be either "F IXED" or "F IXED B" LOCK with a logical record length of 80.
So this is what the error means, how to correct it depends on the SQL you're running and the desired outcome.
What Tutorial is it that you refer to, do you have a link? Is this a real world problem, homework or you expanding your knowledge into mainframe DB2?
Your SQL snippet above is creating a DB, what is the INPUT DATASET file format that you are subsequently running SQL on?
