How can I query TestStand Database quickly?
Hello everybody
I have a performance issue with default TestStand database what puzzled me for long time.
In default database TestStand organize the different test item to different table, if I want to query a test record according to a special Serial Number, the query will look into UUT_RESULT at first to find a GUID then forward to the other table to find a series of GUID bound with this SN which will be used to go into different tables like a numeric values table or pass_fail table to find out the result of each test step.
Half a year ago, we have a small tool embeded with customized TestStand Interface to access this SQL Server 2005 Express database to fetch a SN and all its test results details for faulty analysis. Recently I found it will cost me more than 2 minutes to fetch all related test results of one SN, I tried to write some query in SQL SERVER management studio to get the same thing, the case is still there. And also I check the tables, all tables are already indexed, so I'm quite confused.
Did someone meet similar thing with me? Can you provide some suggestion on this?

What exactly is the query that you are using? Depending on how many records you are attempting to retrieve, two minutes may not be unreasonable. If the database is on a network share, if others are attempting to do similar, large queries, can also affect performance. Making your query into a stored procedure could save some time.

How can i query oracle database data to xml file with c++?
I want query data to xml file directly in my c++ application .
I know the oracle XSU provide interferce for query data to xml
file directly.
But XSU for oracle8i does not support c++.
I do not know if XSU for oracle9i support c++.
can you tell me?
If i do not use XSU to finish my applicayion.
what interface that oracle provide can help me do my work?
thank you !BTW why do you want to migrate oracle database data to db2 database? Any specific project requirement like Parallel run with Oracle database (e.g data replication)? Or any other issues - Cost? Manageability? Availability? Business requirements?
Do you need to do a day-to-day data transfer or it is for permanent migration? -
How can I convert a Database Handle from TestStand to LabVIEW?
I want to use a Database Handle (already created in TestStand by an Open Database step) in a LabVIEW-VI (called from TestStand) to connect it with the "Connection Reference" input of the "Easy SQL.vi"? If I use a directly connection via the "TestStand - Get Property Value (Number).vi" I get back the error message 4101 in LabVIEW. How can I convert the Database Handle?

www.digades.comThe TestStand database step types use the CVI SQL Toolkit to talk to databases. The handle that you are referencing is an internal memory location and not a actual handle that you can directly use. Currently as implemented the handle that is stored in a numeric TestStand property for the connection and the SQL statement are the handle values returned from the CVI SQL Toolkit. So for the connection handle, you could call the CVI SQL Toolkit function
DBGetConnectionAttribute (
int Connection_Handle,
tDBConnectionAttr Attribute,
void *Value);
and get the CVI CAObjHandle reference. With this you could then call the CVI ActiveX function
CA_GetInterfaceFromObjHandle(
CAObjHandle Object_Handle,
const IID *Interface_Id,
int Force_AddRef,
void *Inte
rface_Ptr,
int *Did_AddRef);
to get the actual ActiveX interface reference. This would have to be converted into a LabVIEW reference.
You may want to consider just using LabVIEW to open a new parallel reference only using the toolkit.

How can I use two database in Dataset in SSRS?
Hi,
I am using one query to generate my SSRS report. In that query I am using subquery. Now I am pulling data from multiple tales.
DB used in sub query is different than the rest of the tables DB.(So total I am using 2 DB(Database))
So I see that in SSRS, I can connect query(In DataSet Properties) to one DATA_SOURCE only, how can I use other database which is I used in sub-query?
I have to move this SSRS into PROD and I can't hard code that sub-query's DB name in my query.
Please give me suggestion. Thanks!!
VickyIn SSRS 2008 R2 you can use the Lookup function (http://technet.microsoft.com/en-us/library/ee210531.aspx ) and LookupSet function (http://technet.microsoft.com/en-us/library/ee240819.aspx
Depending on your security set up, you can reference a table in a second database on the same server using a three part name: database.schema.table. This is more likely to work for you if you wrap your SQL command in a stored procedure.

How can we position 5 Database Server for a centralized Database ?
1) We are providing a e governance solution for an organization,where we are providing a centralized database,Client have provided 5 Database server for the same.how can we position the Database Server? there are 5000 Concurrent users and 25000 users,SAN
Storage for approx. 60 TB,Database size of 2 TB and growth of 1 TB every year
2) How many instance can we have for above said Case?
3) How much RAM Required ?Thanks for sharing information!!
DB size is going to be too huge, you need to check for data archival option along with proper compression option.
As per requirement, you need good server setup like; CPU: 4 cpu, 12 cores and RAM will be good to start with 256 GB.
When you say 5 db server, is that it means 5 physical server not db instances rt?
If that is the case then you can go for SQL Server 2014 to use that in memory options along with so many good support for temppdb, query optimization due to cardinality changes, SSD support etc.
Intances will be:
INS1, 2 : main instance and archival instance, using first two servers out of 5 servers.
INS3: DR server, if it will not be active all the time and then we can easily check for 1/4 load on DR server so you can configure AlwaysOn to check INS1 and DR instance to get all HA DR part too.
In case of INS4, INS5 can be used for reporting purpose being configured as other replication to act as local DR too.
Hopefully I have covered all the available objects you have.

How can I know the database is using Cost Based or Rule Based?
Hi all expertise,
How can I know the database is using Cost Based or Rule Based?
If cost based it is using, what methods are need to use to minimize the cost when database is running? And which tables I can see the performance of the database?
Thanks
Amyhow to see database setting ?
use this
SQL> sho parameter optimizer
NAME TYPE VALUE
optimizer_dynamic_sampling integer 1
optimizer_features_enable string 9.2.0
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_max_permutations integer 2000
optimizer_mode string CHOOSE
choose means if table statistics is available then it will use cost
else
use rule based optimizer
for seeing performnace of table use
set autotrace on
and run your query
if it doen't show cost.it means it use rule based
for using cost based
u will calculate table statistics
9i
dbms_stats.gather_table_stats('owner','table');
8i
analyze table <table_name> compute statistics;
hope it will help you

Over 10 years I have built several databases with Appleworks. Now I have a macbook pro. How can I translate these databases to a 10.6.8 program?
Thanks Joe, but that won't work. I've finally found a site that answers the question: http://www.wilmut.webspace.virginmedia.com/notes/aw/page1.html
I can only say that by Apple I have been royally screwed. I'll never buy another mac -- everything I do would simply disappear into cyberspace. -
How can I query all the members of a group using querbuilder? I cannot find any related properties

Hi,
FieldPoint Explorer is no longer used to configure FieldPoint systems. However, I do not think that the configuring your system in FieldPoint Explorer is causing the error.
FieldPoint systems are now setup in Measurement and Automation Explorer (MAX). Information on setting up FieldPoint systems in MAX can be found in the MAX help under: Installed Products>> FieldPoint. Also, I recommend upgrading to the latest FieldPoint driver and version of MAX. The FieldPoint VI's will be slightly different when you upgrade, so there is a good chance that this will eliminate the error.

TomasHello,
many thanks for the reply. Your examples are very usefull for me.
To answer your questions.
An XML structure:
/etd
/header - repeat in each row in output
/account_group/account
/invoice
/da - repeat for each details under "selected "invoice
/detaildc/dc - the lowest level
/detaildn/dn - the lowest level
/dt - repeat for each details under "selected "invoice
/footer - repeat in each row in outputI would like to to have a 1 row for each "record" in /detaildc section and include related nodes at higher levels.
Please see below XML file, which is simplified file of example in first post, but includes a complete xml structure which needs to be queried in db.

Pakistan.now i don't have any archive file. is there any chance to recover the database ?If no archive log files are available you can't recover the datafile.You need to have all the archives from the time of offline backup was taken till the system datafile is lost.

How can i use Unix database in java?
How can i use Unix database in Java?
Message was edited by:
JProI have not a clue about FoxPro, but the db then is FoxPro and not Unix. The better question would be "How do I connect to FoxPro DB running on Unix with JDBC?".
My answer to that would be, search the Internet for a JDBC driver. -
How can I combine two databases, from two computers, to have one combined database of messages?
My old XP computer recently died and I had to build a new Windows 8.1 machine. While I was down I used a laptop as a temporary replacement. Now my new machine is running fine and receiving e-mail, but I now have two databases--one on the new machine and one on the laptop. Both are based on a recent backup, so they are lengthy--except that the new machine's database has a hole in it for the period I was on the laptop and the laptop's database also has gaps. How can I combine two databases into one that includes the messages from both machines?
Thanks in advance,
profsimonieThanks for your reply. My profile folder did not contain any MBOX files. I found them in another folder on another drive. The Import-Export tools simply transferred each folder to the current one as a sub-folder. Then I had to use ctrl-a to select everything in the folder and move them manually to the current folder (such as inbox). Then I could use the other utility you mentioned to remove the duplicates. This had to be done, one folder at a time, to combine each folder. It worked, but I had about thirty-five folders to deal with. The whole process took most of two days to complete. I wish there was a simple way to blend everything together in one action, but I could not find an add-on that would do this.

How can I get Connection(Database Connection)on my backing bean
hello guys!
How can I get the Database Connection on my managed bean?
I want to use this connection for my reports.
thanks a lot!
alvinAlvin,
You can access the data provider through ADF the binding. The data provider represents the business service you use. Once you have a handle to this you can get the connection.
You don't mention the business service, so I cannot help you more than this. If it is ADF BC, have a look at http://download.oracle.com/docs/html/B25947_01/toc.htm and the stored procedure section. Steve Muench explains a trick to access the "real" JDBC connect used by ADF BC

How can this query avoid full table scans?
It is difficult to avoid full table scans in the following query because the values of column STATUS reiterant numbers. There are only 10 numbers values for the STATUS column (1..10)
But the table is very large. there are more than 1 million rows in it. A full table scanning consumes too much time.
How can this query avoid full table scans?
Thank you
SELECT SYNC,CUS_ID INTO V_SYNC,V_CUS_ID FROM CONSUMER_MSG_IDX
WHERE CUS_ID = V_TYPE_CUS_HEADER.CUS_ID AND
ADDRESS_ID = V_TYPE_CUS_HEADER.ADDRESS_ID AND
STATUS =! 8;Edited by: junez on Jul 23, 2009 7:30 PMYour code had an extra AND. I also replaced the "not equal" operator, which has display problems with the forum software
SELECT SYNC,CUS_ID
INTO V_SYNC,V_CUS_ID
FROM CONSUMER_MSG_IDX
WHERE CUS_ID = V_TYPE_CUS_HEADER.CUS_ID AND
ADDRESS_ID = V_TYPE_CUS_HEADER.ADDRESS_ID AND
STATUS != 8;Are you sure this query is doing a table scan? Is there an index on CUS_ID, ADDRESS_ID? I would think that would be mostly unique. So I'm not sure why you think the STATUS column is causing problems. It would seem to just be a non-selective additional filter.
