Extreme database

Would you guide me where to download the free extreme database for learning Crystal Report Designer?
Thanks

Hi,
Xtreme database is sample database which comes with Crystal report designer.
Try to find it from the directory where you have installed Crystal Report designer.
Like: c:\Programfiles\Business Objects\Common\3.5\Samples\..\databases...
If you dont have xtreme database at this location then i would suggest you to download trail version of crystal reports from [here|http://www.businessobjects.com/product/freetrials.asp]

Need to Extract Image from Database for Report

Greetings,
I have two databases that I could work with; both are for card access users. One is an old Access 98 database, the other is a SQL database,
In the tables I can "see" references to employee_photo and badge_picture_path respectively, but when I run the Report, the Image is not retrieved.
Any ideas how I can overcome this ?
I am trying to create a hard copy in a binder, so that new guards can thumb through the binder and familiarize themselves with employees.
Thanks
Peter

Hi Peter,
What format are the pcitures saved in. I believe they have to be either BMP or JPEG. Any other formats will not work in Crystal.
Have a look with the sample Extreme database. The Employee table has a picture field, very similar to what you are using. If you create a simple report with it, can you see the pictures?
Thanks,
Brian

Architecture of database heavy application

A program I'm currently designing is extremely database heavy, almost anything the user does will alter the database, or read from it. Now I have one interface which defines all these operations, and one database class which implements this.
The result is that that class is huge, it contains logic for creating users, editing them, creating events, showing events to the user, editing, adding friends, adding items to a product, ....
On the one hand I can argue this does not violate SRP, because the whole use is database communication. On the other hand, this is a lot of code for one class.
Are there any design patterns that solve this, or is this acceptable?

Connecting to Xtreme db

Hi All,
I have a sample db extreme database.
I need to create a universe with this db
So I am creating relational connection .But getting some error.
dont know how to select the db.
Please help

Hi Divya,
First you have to create the ODBC for xtreame MS Access. Please refer below link.
Setting Up an ODBC Data Source For MS Access
In above link the datasource name is TestChannel . So after creating this TestChannel data source will appear in data source dropdown box .Please select that and test the connection. It will work very fine.
Thanks

CR XI & XI R2 - PutLocation() Extremely Slow on Oracle Database

Hello,
I have an issue very similar to others posted in this forum, but was asked to start a new thread.
I'm using Crystal XI and XI R2,updated with SP6.
I develop using C++ on VS2008 using the crystal COM object.
I have common database tables, in which I have views on these tables. The views depict a collection, and when the report is to run on a different collection I need to change the views on all of the tables (including those in subreports), as well as provide the credentials for connection.
I'm using Oracle 10g, and changing a couple of properties using the following sequence for each table to change the login information and the table's current view (each view is a portion of the overall table):
IDatabaseTablePtr table = tables->GetItem(tableN);
table->SetLogOnInfo(TheApp.GetDataSource(), TheApp.GetDatabase(), userID, pwd);
char tableLocation[201];
char tempTable[201], newTable[201];
strcpy(tableLocation, table->GetLocation());
// make new table name, put into newTable
table->PutLocation(newTable);
if (!table->TestConnectivity())
ShowCrystalRE_Error(job);
Stepping through in my debugger, the SetLogOnInfo seems very quick, it's the PutLocation( ) that seems to be taking alot of time, several seconds per call, whereas the other calls are as quick as I can step through my code.
Any help would be greatly appreciated.
This is extremely fast on SQL Server, only noticeably slow on Oracle.
My database connections for the report utilize ODBC (The ORACLE installed driver, not the MS driver), which is how our application talks to the database, and provides a connection to crystal.
I can have upwards of 20 tables/views in a report, and this can take 1/2 to a full minute to accomplish.
In addition, I optionally provide a user the ability to add criteria and sorting to the report; and perform a table/column collection to show them to the user for seleciton. This same process is used on all views (including those in subreports), so proper data lists can be provided from the correct views.
Does anyone have a solution for this?

Ludek, thanks for the response.
I think it might be best if I cite your response and comment on it.
1) Only CR 10.5 and CR 2008 (12.x) are supported in .NET 2008.
I'm using VS2008 with C, not .Net.   Everything works fine, including all of the API calls, it is only the performance of this particular call to PutLocation( ) that is slow using Crystal engine XI.
2) You actually appear to be using the RDC (craxdrt.dll) in .NET, which is also not supported in .NET - any version of .NET. See this article for details and also see this blog.
See #1 above, not using .NET.
3) You are using SetLogOnInfo. This method was deprecated in version 9 of Crystal Reports and you now must use the connection properties bag. See this article for more details.
     I'm previewing the article you cited above, iew the Connection Property to see if this will work for me.
If you somehow manage to overcome the above issues, you will have to also resolve the issue of how and which CR runtime to distribute. RDC? CR for .NET? Both?
      For distribution, I copied the 4 MSM files from the installation to my Installshield Redistributables, select all four to be included in my package, the license is the only one requiring a keycode, which I took as the product code used to do my install (as instructed by Macrovision/Business Objects support several years ago when we first upgraded to Crystal XI and I did our interface rewrite to use the COM object.
CrystalReports11_RDC_Designtime.msm
CrystalReports11_RDC_License.msm
CrystalReports11_RDC_Reportengine.msm
CrystalReports11_RDC_Runtime.msm
With the recent upgrade to SP4 (which made Crystal XI into XI R2) and then SP6, I found the following which I've started using since March 2nd in an attempt to resolve the Performance issue outlined in this thread.
CrystalReports11_5_RDC_Designtime.msm
CrystalReports11_5_RDC_License.msm
CrystalReports11_5_RDC_Reportengine.msm
CrystalReports11_5_RDC_Runtime.msm
Do you have any further insight while I preview the "Report Designer Component 9" PDF you cited?
Thanks again in advance,
Bob

Changing database location per Table at runtime is extremely slow in viewer

We are using the Crystal Reports 2008sp2 Viewer in windows forms .NET
application to display various reports based on a Pervasive database. The
C# code dynamically changes the database table locations at run time. The
location needs to be set for each table since the location may be different
for each table in the report.
We have tried to methods to change the location.
1) Set the Table.Location property in the ReportDocument.Database.Tables
collection.
foreach (Table table in rd.Database.Tables)
Table.Location = "New Path";
2) Set the TableLogOnInfo properties.
      TableLogOnInfo logonInfo = new TableLogOnInfo();
      logonInfo = table.LogOnInfo;
      logonInfo.ConnectionInfo.ServerName = dataPath;
      logonInfo.ConnectionInfo.LogonProperties[0] = new NameValuePair2("Data
File", dataPath);
      logonInfo.ConnectionInfo.LogonProperties[0] = new NameValuePair2("Data
File Search Path", path);
      table.ApplyLogOnInfo(logonInfo);
Both of these methods work, but have extremely slow performance. Both
methods take between 2 and 3 seconds to execute per table. Since many of
our reports have 20 - 30 table references ( sometimes more ), this can add
an additional 1-2 minutes to the display of a report.
It seems that the Crystal viewer object is doing some sort of verification
every time the database location is changed. We have noted that as the
location is changed, the database is being accessed by the viewer. Please
advise as to how to stop this behavior. Is there a way to set the location
without the viewer verifying the change?
This problem is turning reports that run in the 2008 Report Designer in 3 seconds into reports that take
many minutes to run. We will hear nothing but screaming from our 300 customers.
Thanks for any help.

Airport Extreme & Remote Access for database application

Hi There,
I have spent an entire week of my time between apple, apple consultants and networking experts trying to get a access remotely to a simple database program inside an wireless network. I have read the discussions on remote access thru the AEBS and port mapping.
I'm hoping an user here can help me with a foolproof solution that the 'apple experts' can seem to design?
All that is required to get this program up and running remotely is the ip address of my computer inside my wireless network. I have set that this computer to a static address but since my dsl provider uses dynamic IP's this doesn't seem to work (or it does for about 12 hours until the IP address of my AEBS is changed). Will port mapping work for me or is my only solution an up-charged static IP?
Thanks in advance for any suggestions......the thought of spending another week on this is frightening!

If your ISP is refreshing the dynamic host configuration of the public ip address assigned to the ISP provided router you will need to request a static ip address from your service provider.
The addresses that are used "inside of your network" are private ip addresses. If you are using the (1) public address for your router (APE)(Apple airport extreme) from the ISP what you are trying to do will not work very well since your router (APE) will use the Public IP address to provide access to the public internet for your private network using the private ip addresses you have used to create your subnet and told your router (APE) about. Three private IP address schemes can be used for a private internet. One for each class. Class A 10.x.x.x/8, Class B 172.16.0.0/12 and Class C 192.168.0.0/24. Translated using dynamic NAT (network address translation with overload) making your LAN hosts using private IP addresses to seem as if they are using a public ip address allowing access to the public internet where only public ip addresses can be used.
PAT (port address translation) is what you are trying to accomplish. For PAT you must have a valid public ip address from your ISP and a private address from your network assigned to interesting host. Use the private ip assigned to the interesting host in the port mapping panel of airport admin that you wish to allow access to via the global internet as well as the tcp or udp port number for the traffic to be directed. For example port 5003 for FileMakerPro or port 20 and 21 for ftp. You should also implement security policies to protect your network and hosts.
Since you said that it works for 12 hours you must have the basics set up correctly. All you need now is to get a static ip address assigned to you from your ISP or use a service such as http://www.dyndns.com/
Hope I didn't ramble on too much

Webfolder access to XML stored in database is extremly slow (XP)

Hello,
I made a webfolder to access my XML-documents stored in the database over explorer. My OS is XP. But the access is extremly slow. When I access the documents from a Windows2000 computer the access is fast. Has anybody an idea what could be the reason for this??
Any help appreciated.
Anna

None of them go throug the proxy server. Oracle suggests to install some XP-Patches what I have done. Now the webfolder access is normal. It is an XP ServicePack1 - problem.
Thanks.

Database is extremely slow and alert_log is not updateing

Please HELP!!!
Our database is experience a big performance issue. It extremely slow.
At the same time our alert_log is not updating. Last entry was made on 11/15/05.
Can this be related? The alert_log size is 10.6MB. Is there a limit to size of alert_log?
What are the appropriate steps for renaming alert_log?
Does anyone experiences the same issues before?
Thank you in advance,
Sonya

on Windows
Select the alert log and press right mouse buttong, select rename and change the name.
From dos prompt, go the directory/location where alert log exists, use the following command:
ren alert_ORCL.log alert_ORCL..log.old
on UNIX
go the location of alert log, use the following command.
mv alert_ORCL.log alert_ORCL.log.old
(give alert file name as exists at your place)
Important: No need to shutdown the database. Once you rename the file, connect as sysdba and switch the logfile and see whether oracle has create the new alert log or not.
alter system switch log file;

Loading time is extremely long - Any way to create a database?

I'm cutting a feature using Premiere CC. There are over 6,000 files in the project including video (ProRes Proxy) and audio files (wavs). The project currently takes over ten minutes to load, then once loaded my system is extremely slow. I am running a 2.2 i7, Radeon HD 6750M 1024mb, w/ 8 gigs of ram on a macbook pro. Is there anyway to create a database of some sort so the file loading time doesn't take so long? Or is there anything I can do to speed up the loading time in general?
Thank you.

If I may be so bold as to offer workflow advice? When working with an underpowered computer, there are ways to work around the RAM issues and the slow processor.
Break up the project into various sections. Work on the intro and the credits in one project, work on indoor scenes in another, outdoor in another, or some other manner that allows you to use multiple projects. When you are done with a section, or a scene, or whatever, you can nest the main sequence and import that new sequence into the "main" project where you can then assemble all of the parts.
If you really need to go back and make adjustments, just reopen the original project for that sequence and do what you need to do. Then delete the sequence in the "main" project and import it again. Or, instead of doing that, just export each project's main sequence and combine the clips into one new project. You would not use this method for the final export, but it will save you the hassle of importing sequences over and over if you are changing things a lot. When it all looks good, then import all of the projects into one project and combine the sequences into your movie.
Keep in mind that a Premiere Pro project is just an XML file and all of the text has to be read into the program, basically one line at a time. So keep the number of lines to a minimum. Even in CC, it is still XML, just zipped up.

Database export/exports are extremely slow

We run PeopleSoft (PeopleTools version 8.46) applications on Oracle 10g (10.1.0.3). database exports/imports were extremely slow, so when we contact PeopleSoft customer connection, we were advised to modify the init.ora file with the "_optimizer_cost_based_transformation=off". After we set the init.ora file, exports/imports are very fast.
What is optimizercost_based_transformation? will database performance have any effect by setting this parameter? Does anybody has issues with 10g export/import issues?
any help?
Thanks,

Here is the extract from PeopleSoft customer connection -
. Required INIT.ORA Parameters for Oracle 10g
. Change #1 - optimizercost_based_transformation=off
According to Oracle support: "This parameter controls whether query transformations (sub-query unnesting, complex view merging and push join predicate ) are performed using an algorithm that relies only on optimizer cost (new in 10g) or an algorithm that uses a combination of optimizer cost and heuristics (pre-10g). "
Can anbody tell me how extaclty this parameter will affect the performance of the system? Althoght we didn't see any performance issues right now (We are just in the process of implimentaion) Going forward, i am worried to have this im my init.ora file.
Any thoughts/suggestions related to this topic is helpful.
THanks,

Backup for SQL 2008R2 database taking extremely long!

Runnig DPM SP1 on hostserver backing up over to a different network. Only failing for SQL 2008 r2, where it takes a very very long time. It takes so many hours, that the job even laps its own self. Is there any other factors that can influence
this, leaving network, disk I/O and size of database on the side? Anyone with same problem? any solutions? Pretty desperate here. Thanks in advance!

Hello Samir,
Volume does not have any encryption or dedup. The actual first backup took over 20 hours. This is with dpm creating the allocated the volume for the backup. And then every backup sycronisation took about 7-8 hours. SQL database is about 1.3 TB. I understand
this big, but still they has to be another reason to why it would take way long.
thanks in advance!

Making https: connection from java code loaded into Oracle 8i database

A bit of a blast from the past, really, as 8i provides a JVM at 1.2.2.
I need to provide an PL/SQL function which accesses a RESTful web service requiring https connection. Got the call working under 1.2 locally without much trouble using:
static {
        System.setProperty("java.protocol.handler.pkgs",
                "com.sun.net.ssl.internal.www.protocol");
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
    }The trick is to get the Oracle database to run the code internally. What libraries do I need where? I get an extremely unhelpful NoClassDefFoundError, without mention of the offending class.
By doing loadjava with jcert.jar,. jnet.jar and jsse.jar (the libraries I'm using with the test program) I can get loadjava to accept and allegedly resolve the class.

Database base storage stress test

Hi,
I have a ucm 11g instance up and running with SSO.
I need to test database storage against filesystem storage.
Does anyone have any suggestions on how to test this?
Also I'm sure I read somewhere (but I can't find it now) that once I go in one direction I can't go back, does anyone have any details about this?
Many thanks
James

First of all, take a look at File Store Provider (here: http://download.oracle.com/docs/cd/E14571_01/doc.1111/e10792/c02_settings005.htm#CSMSP445)
In general, filesystem storage is always used even if you store data in the database, in the end. It is, though, understood as a temporary storage. In theory, you can keep your files in both locations and I see no reason why you should not be able to go from FS to DB and back, BUT you have to consider consequences (you might have to rebuild indexes or even migrate data from one storage to the other).
As for stress tests, first you have to decide WHAT you want to test. Potential candidates are:
- checkin of a single item (wasted effort: since FS is always used as an intermediate storage it will always be a bit faster)
- mass checkin (e.g. from Batch Loader - especially if you use Fast Checkin settings, db can be a bit faster, but you will need a real lot of small files)
- search
- update (metadata - wasted effort: should be the same)
- backup
- migration of content
Then, you will have to setup two environments with more-or-less the same conditions (CPU power, memory, disk speed).
And finally, you will have to create and run you test cases. I'd suggest to automate stress tests via writing a program calling the same services with the same data. Use WebServices (if non-Java) or RIDC (if Java).
Alternatively, if your task is "to get results" rather than "perform stress tests", you could try to approach consulting services or project managers to provide some normalized results for you. Something can be obtained in this whitepaper: http://www.oracle.com/us/products/middleware/content-management/ecm-extreme-performance-wp-077977.pdf

Crystal Report Viewer Not Releasing Oracle Database Connections

I have a very simple vb.net 3.5 web application that uses the Crystal Report viewer 2008 to open a report. My requirements are as follows:
1. Reports are built by another company and provided to us and used in a web environment
2. All reports contain parameter fields
3. The web application must be generic enough that a report can be added to a list and the user simply selects the report and provides database login information. The Crystal report viewer with handle the request for parameter values and prompt the user for their values.
4. All reports connect to an Oracle 10g server.
The above requirements have been meet and we have an extremely simple web application that runs the reports. It is working very well other than the crystal report viewer is not releasing the database connections. This is bad because the credentials are on a per user basis and that same user must login to a different oracle application simultaneously. They are being denied access because the credentials are already in use. We do not have control nor influence over the policies in use on the Oracle server. Ideally we would like to control the Crystal Report viewer so that it closes connections after use.
The web application code is:
Private Sub viewReports_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Not IsPostBack Then
ConfigureCrystalReport()
End If
End Sub
Private Sub ConfigureCrystalReport()
'Load the Crystal Report viewer with a report.
Try
Dim reportPath As String = Server.MapPath(Session("reportname"))
crViewer.ReportSource = reportPath
Catch ex As Exception
Response.Write(Server.MapPath(Session("reportname")) & "
" & ex.Message.ToString & "
" & ex.StackTrace.ToString)
End Try
End Sub
Can anyone shed some light on this topic? Thank you

Hello, Timothy;
By default, having the report in session will hold it open for 20 minutes.
If you create the report as a ReportDocument object you can take it out of session and release it more efficiently. That will release the connection.
    Private Sub ConfigureCrystalReports()
        If (Session("hierarchicalGroupingReport") Is Nothing) Then
            hierarchicalGroupingReport = New ReportDocument()
            hierarchicalGroupingReport.Load(Server.MapPath("Hierarchical Grouping.rpt"))
            Session("hierarchicalGroupingReport") = hierarchicalGroupingReport
        Else
            hierarchicalGroupingReport = CType(Session("hierarchicalGroupingReport"), ReportDocument)
        End If
        myCrystalReportViewer.ReportSource = hierarchicalGroupingReport
    End Sub
In the Form Unload of the Viewer:
            'Take the report out of session
            Session("hierarchicalGroupingReport") = Nothing
            Session.Contents.Remove("hierarchicalGroupingReport")
            'Clean up the ReportDocument object
            hierarchicalGroupingReport.Close
            hierarchicalGroupingReport.Dispose()
            hierarchicalGroupingReport = Nothing
            GC.Collect()
