1) Open Command Prompt 2) Create directory for Database and Logs                    mkdir c:\data\db                     mkdir c:\data\log 3) Create a file at C:\mongodb\mongod.cfg and  specifies both systemLog Path and Storage database       path   Add following in mongod.cfg file : systemLog : destination : file path : c:\data\log\mongod.log storage : dbPath : c:\data\db 4) Create service named as "MongoDB" using following command sc.exe create MongoDB binPath= "C:\mongodb\bin\mongod.exe --service --config=\"C:\mongodb\mongod.cfg\"" DisplayName= "MongoDB" start= "auto" 5) To remove MongoDB service use following command sc . exe delete MongoDB  

These two collations are both for the UTF-8 character encoding. The differences are in how text is sorted and compared. Note: in new versions of MySQL use utf8mb4 , rather than utf8 , which is the same UTF-8 data format with same performance but previously only accepted the first 65,536 Unicode characters. Accuracy utf8mb4_unicode_ci is based on the Unicode standard for sorting and comparison, which sorts accurately in a very wide range of languages. utf8mb4_general_ci fails to implement all of the Unicode sorting rules, which will result in undesirable sorting in some situations, such as when using particular languages or characters. Performance utf8mb4_general_ci is faster at comparisons and sorting, because it takes a bunch of performance-related shortcuts. On modern servers, this performance boost will be all but negligible. It was devised in a time when servers had a tiny fraction of the CPU performance of today's computers. utf8mb4_unicode_c...

    How to show records in same order where IDs are put into the IN() clause?     1) SELECT id FROM table1 WHERE ... ORDER BY display_order , name 2) SELECT name , description , ... WHERE id IN ([ id ' s from first ])   The issue is that the second query does not return the results in the same order  that the IDs are put into the IN() clause.    Solution :-  SELECT name , description , ... FROM ... WHERE id IN ([ ids , any order ]) ORDER BY FIELD ( id , [ ids in order ])

Blob data used MySQL charset which is in my.ini default-character-set=latin1 Suppose I have a table with a BLOB field. The charset of the table is UTF-8. I connect to the DB and "SET CHARACTER SET utf8". Then I save binary data into the field. Then I retrieve the data, and it's not what I saved (corrupt). Because while retrieving data blob data used mysql default charset set. Ref : http://stackoverflow.com/questions/14734812/is-a-blob-converted-using-the-current-default-charset-in-mysql

After passing userid and password in URL and page load it ask for user and password, seems pentaho server does not recognize the parameters. check here for the workaround (it's on the comments):  http://jira.pentaho.com/browse/BISERVER-10708 Workaround is to edit the system/applicationContext-spring-security.xml file and change the parameters for the filterChainProxy. Lines 22 and 23 should be replaced by:         /api/**=securityContextHolderAwareRequestFilterForWS,httpSessionPentahoSessionContextIntegrationFilter,httpSessionContextIntegrationFilter,requestParameterProcessingFilter,basicProcessingFilter,anonymousProcessingFilter,exceptionTranslationFilterForWS,filterInvocationInterceptorForWS         /plugin/**=securityContextHolderAwareRequestFilterForWS,httpSessionPentahoSessionContextIntegrationFilter,httpSessionContextIntegrationFilter,requestParameterProcessingFilter,basicProcessingFilter,a...

Installed Pentaho Repository Synchronizer with branch Trunk This plugin copies a version of libpensol.*.jar to the server's WEB-INF/lib. It's possible that on Windows boxes there's an error upgrading the repositorySynchronizer. If that happens, stop the server and delete the WEB-INF/lib/libpensol.* jar file(s)

To hide the .CDA files, its no use to the end user to see the datasource in the treeview so edit: biserver-ce/pentaho-solutions/system/cda/ plugin.xml And comment the lines between: <!– <content-types> … </content-types> //–>

In order to generate reports from OpenERP v7 you need to have Pentaho Report Designer downloaded from Pentaho’s website and unzipped on your computer. The package is a binary package which doesn’t need installation on your computer and hence you can run it from the folder where you unzipped it. Here are the steps that you can follow to setup and run Pentaho Report Designer to Connect to OpenERP v7 and create reports: Pentaho Report Designer v3.9.1 is available from Sourceforge.net here . Download the package which is suitable to your computer architecture. For Windows Download  prd-ce-3.9.1-GA.zip You need Java JDK Version 1.6.0 and above. You can download java from www.java.com and install it on your computer. Once Java is fully installed run the file named “set-pentaho-env.bat” from Pentaho folder. This will setup your environment and then click on “report-designer.bat”. Pentaho Report Designer should run now. Close it now and move on to the next step. Report Desi...

Dynamic pivot tables (transform rows to columns)   in MySql there is no function of automatically table transformation. Surely we can use some program (tool), which is able to connect to MySql and execute data transformation. But in this case we want to do it manually, and we have one variant – to write a query which will execute the data rotation in the table   http://buysql.com/mysql/14-how-to-automate-pivot-tables.html   http://stackoverflow.com/questions/10925445/mysql-select-dynamic-row-values-as-column-names-another-column-as-value   http://stackoverflow.com/questions/10986031/sql-dynamic-view-with-column-names-based-on-column-values-in-source-table?rq=1

Caused by: java.sql.BatchUpdateException: Packet for query is too large (1434172 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable. The max_allowed_packet variable can be set globally by running a query. However, if you do not change it in the my.ini file (as dragon112 suggested), the value will reset when the server restarts, even if you set it globally. To change the setting for everyone until the server restarts: SET GLOBAL max_allowed_packet=1073741824;
