java.lang.IllegalStateException: Imbalanced frame stack! (exit() called too many times) !

If you started using SpringSource Insight,It's highly recommended to increase the memory of the tc Runtime Instance to more than what your application requires on its own . The following is the exception you might see in case there is not enough memory.
type Exception report
message

descriptionThe server encountered an internal error () that prevented it from fulfilling this request.
exception
java.lang.IllegalStateException: Imbalanced frame stack! (exit() called too many times)
com.springsource.insight.intercept.trace.ThreadLocalFrameBuilder.exit(ThreadLocalFrameBuilder.java:61)
com.springsource.insight.collection.DefaultOperationCollector.exit(DefaultOperationCollector.java:111)

note The full stack trace of the root cause is available in the VMware vFabric tc Runtime 2.6.2.RELEASE/7.0.22.A.RELEASE logs.

There are few options to resolve this issue.
  1. Increase the max heap
    For example: -Xmx512m
  2. or max PermGen size JVM option.
    For example: -XX:MaxPermSize=256m
  3. Increase the Spring insight max frame
    For example: -Dinsight-max-frames=6000
OR you can have all of the above JVM parameters.

Get the the difference between two dates in MS SQL

The DATEDIFF() function returns the difference between two dates
Syntax: DATEDIFF ( datepart , startdate , enddate )

Following is an example for the DateDiff()
DECLARE @startdate datetime ='2011-11-14 02:00:06.957';
DECLARE @enddate datetime = '2011-11-16 05:00:15.490';
SELECT DATEDIFF(day, @startdate, @enddate) as dayDifference,DATEDIFF(HOUR, @startdate, @enddate)as hourDifference
Output

dayDifference hourDifference
2 51


Similarly the following are the available datepart Options on the DateDiff() Function.

year(or yy or yyyy)
quarter(or qq or q)
month (or mm or m )
dayofyear(or dy or y )
day (or dd, d )
week(or wk or ww)

hour(or hh)
minute(or mi or n)
second(or ss or s )
millisecond(or ms)
microsecond(or mcs)
nanosecond(or ns)

Get the Row Numbers as a separate column on MS SQL Query

I was trying to execute a new query where I need the Row number as a new column on the result itself. I used the SQL Function ROW_NUMBER() to get the row number.
Following query gives the Report Path with the HitCount along with the added Row Number.

select ROW_NUMBER() OVER(ORDER BY count(ReportPath) DESC) AS 'Row Number', ReportPath,count(ReportPath) as HitCount
FROM [ReportServer].[dbo].[ExecutionLog2]
Group by ReportPath
Order by HitCount desc


Cheers !

How to parse multi value parameter from SSRS Report !

While writing an SSRS Report, I had to parse a multivalued parameter and stored it on a temp table. After some googling i came up with the following solution. @id is the multi valued parameter that need to be parsed. Following is the sample code that you can used to parse and put the values on a temp table.


-- @uid is the parameter. Lets define the parameter for testing.

declare @uid as nvarchar(200)
set @uid='u01052901,u01052789,u01052897,u0105345,u08023432,u0234324,u23479879'

create table #TempIDTable (
slice varchar(50))
declare @index1 int
declare @u_id nvarchar(4000)
set @index1 = 1
if @uid is null
set @index1 = 0
while @index1 !=0
begin
set @index1 = charindex(',',@uid)
if @index1 !=0
set @u_id = left(@uid,@index1 - 1)
else
set @u_id = @uid
insert into #TempIDTable select @u_id
set @uid= right(@uid,len(@uid) - @index1)
if len(@uid) = 0
break
end

Select * from #TempIDTable
--drop table #TempIDTable

Schema Spy, A Graphical Database Schema Metadata Browser.

Schemaspy is a java based tool that analyzes the metadata of a schema in a database and generated the visual representation of it. The output is highly user friendly. You can browse through table via child and parent table relationship.

Schema Spy uses the dot executable from graphviz to generate the graphical representation of the schema and its relationship. Graphviz is the graphics visualization software that takes descriptions of graphs in a simple text language, and make diagrams in several useful formats such as images and SVG for web pages, Postscript for inclusion in PDF or other documents; or display in an interactive graph browser.

Following is the steps to execute the SchemaSpy tool (for a sample MYSQL database.)
1. Download and install Graphviz from http://www.graphviz.org/Download..php
2. Download the Schema spay jar file, Schemaspy_x_y_z.jar from http://sourceforge.net/projects/schemaspy/files/
3. Download the corresponding JDBC Connector and have it on the same source folder where the schemaspy_x_y_z.jar resides. For example for a mysql database, I would simply download mysql-connector-java-5.1.5.jar or any other latest version of mysql connector.
4. Now from the source location of your Schemaspy_x_y_z.jar file, execute schemaspy to generate the graphical representation of the schema of your database, as shown on the following syntax

java -jar schemaSpy_x.y.z.jar -t database_type -dp mysql jdbcdatabase_connector -hq -o output_Directory -db databaseName -u username -p password
for example : java -jar schemaSpy_4.1.1.jar -t mysql -dp mysql-connector-java-5.1.5.jar -hq -o out -db bisudatabae -u bishow -p north
