Automating your Essbase Cube [ 310 ] Clear application log A good practice for an Essbase administrator would be to clear the application log as often as possible. If the application log le is allowed to get too large users, a marked decrease in system performance is seen. The good news for the Essbase administrator is that there is no need to log on to the Essbase server through EAS to clear the log le. The system administrator can write a MaxL script and use it to clear the log le on a weekly basis. Be sure to back up the log le for audit trails according to your company's standards. Syntax: alter application <App-Name> clear logfile; Enable/Disable start up/auto startup In an application's properties you can set the application to start whenever the Essbase server is started or you can start an application at the rst user request to log on. These properties can be set by the administrator with a MaxL command. startup /* Allow user to start Application */ If startup is enabled, the users can start the application upon log on. If startup is set to disabled, the users will not be able to log on, if the application is not already started. Syntax: alter application <App-Name> enable startup; alter application <App-Name> disbale startup; autostartup /* Start Application when Essbase Analytical Server starts */ If autostartup is enabled, the application will start as soon as the Essbase analytic server is started. If autostartup is disabled, the application will not start when the Essbase analytic server is started. Syntax: alter application <App-Name> enable autostartup; alter application <App-Name> disable autostartup; This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Chapter 8 [ 311 ] The MaxL alter statements are some of the more commonly used MaxL statements. Do not let this give you any indication as to the usefulness of every single available MaxL command. You may go for years and never use a command that someone else uses every day. As an Essbase administrator it is upto you to decide what works best in your individual situation. Display application This statement displays all of the information about all of the applications on the server or you can specify a specic application. Syntax: display application all; display application <app-name>; Drop application The drop application command will drop an empty application. To remove an application that has databases in it, use the cascade option and if some of the objects are locked, then you can use the force option. Syntax: drop application <App-Name> cascade; drop application <App-Name>cascade force; Working with an Essbase database from MaxL In the Database MaxL object, you can use the same verbs like Alter, Create, Display, and Drop as you have used in the alter application statements, but these are at the database level. Just like the MaxL statements that are used for altering an Essbase application, there are many MaxL commands that are used to alter an Essbase database as well. And, just like the application level MaxL commands, the database level commands directly correspond to the settings available to you through the EAS tool.

Let's see how each of these MaxL verbs will be used in the Essbase database object. Creating or replacing a database Using a MaxL statement you can create a new standard database or a new currency database. With the create statement you can also make a copy of an existing database. Syntax: This statement is for a standard Essbase database: create database <app-name.db-name>; This statement is for a currency Essbase database: create currency database <app-name.db-name>; This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Chapter 8 [ 313 ] Code Sample: create database 'ESSCAR'.'ESSNEW'; replace database 'ESSCAR'.'ESSBKP' as 'ESSCAR'.'ESSCAR'; or create database 'ESSCAR'.'ESSBKP' as 'ESSCAR'.'ESSCAR'; Altering a database Just like the application alter command there is an alter command for the databases. How about we walk through some of the more commonly used ALTER commands? Enable/Disable commands These MaxL commands are used to enable or disable some of the more commonly updated Essbase database properties. This syntax shows how to enable/disable Essbase database properties: alter database <Dbs-name> enable | disable two_pass_calc | aggregate_missing | startup | autostartup | compression >; Code Sample: alter database 'ESSCAR'.'ESSCAR' enable autostartup; alter database 'ESSCAR'.'ESSCAR' enable two_pass_calc; alter database 'ESSCAR'.'ESSCAR' disable startup; alter database 'ESSCAR'.'ESSCAR' disable aggregate_missing; alter database 'ESSCAR'.'ESSCAR' enable autostartup; Archive commands An Essbase database can be archived to a le. These MaxL commands are used for archiving a database. Use the begin archive to file to begin the archive export and end archive to end the archive export of the database. We will talk more about archiving in the next chapter. Syntax: alter database <db-name> begin archive to file <File-name>; alter database end archive; This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Automating your Essbase Cube [ 314 ] Set commands In MaxL, you can also use the set commands. Some of the most widely used set commands are retrieve_buffer_size, data_cache_size, index_cache_size, currency_conversion minimum permission, compression, lock_timeout, implicit_commit_after n blocks, and many more. Some syntax and code samples are listed below for the set commands. Syntax: alter database <Db-name> set <SET-COMMAND>; Code Sample: alter database 'ESSCAR'.'ESSCAR' set data_cache_size 4096; alter database 'ESSCAR'.'ESSCAR' set retrieve_buffer_size 15360; alter database 'ESSCAR'.'ESSCAR' set currency_database 'ESSCAR'.'ESSCURR'; /* This links a Standard database to its currency database */ alter database 'ESSCAR'.'ESSCAR' set compression zlib; alter database 'ESSCAR'.'ESSCAR' set note 'DATA IS UPATED on 02/08/2009'; Reset database In MaxL, you can clear the data, LRO objects, and the entire outline in one single statement. Use extreme caution while using this command as there is no undo function to save you. Syntax: alter database <Db-Name> reset <all | data>; Code Sample: alter database 'ESSCAR'.'ESSCAR' reset all; alter database 'ESSCAR'.'ESSCAR' reset data; Rename database Using the alter statement, you can also rename the database to a new name. Syntax: alter database <Db-name> rename to <new Db-name>; This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com . licensed for the sole use by Paul Corcorran on 5th July 20 09 8601 ave. p #1, , lubbock, , 794 23 Download at Boykma.Com Automating your Essbase Cube [ 312 ] As you are reading through the examples. licensed for the sole use by Paul Corcorran on 5th July 20 09 8601 ave. p #1, , lubbock, , 794 23 Download at Boykma.Com Automating your Essbase Cube [ 314 ] Set commands In MaxL, you can also use. startup; autostartup /* Start Application when Essbase Analytical Server starts */ If autostartup is enabled, the application will start as soon as the Essbase analytic server is started.
