This entry is part of the Java MBO performance optimization golden rules series. Sometimes you have to perform some complex logic or you have to join several tables to retrieve a piece of data. In other cases there is a piece of code where performance is critical. In such cases it may be hard to […]
This entry is part of the Java MBO performance optimization golden rules series. It is important to know the difference between close(), cleanup(), and clear() methods and use them to free up resources as soon as possible. close(): Close the cursor, release the database resources (result set), SQL statement, and connection key. Does not release […]
This entry is part of the Java MBO performance optimization golden rules series. This tip regards the correct handling of transactions in TPAE. The important concept to understand is that MBOs obtained via relationship are included in the same transaction as the parent MBO set. When any MboSet in the transaction is saved, all MboSets […]
This entry is part of the Java MBO performance optimization golden rules series. The initValue() method is the first method executed after the MBO constructor. It is typically used to initialize attributes on new records and to set default values.The init() method is called after initValue(). It is typically used to set current attribute as […]
This entry is part of the Java MBO performance optimization golden rules series. If an MboSet is used for traversing forward only and not to be saved make it discardable by setting the DISCARDABLE flag.The following snippet shows how to do it. MboSetRemote mboSet = getMboSet(“ASSET”);mboSet.setFlag(MboConstants.DISCARDABLE, true);MboRemote mbo=null;for(int i=0; (mbo=mboSet.getMbo(i))!=null; i++){ …} Using a discardable […]
This entry is part of the Maximo Java Development series. In this post I have collected the most important Maximo Business Objects (MBO) development performance tips and suggestions that I have learned during my job as a Maximo Consultant.These suggestions are partly distilled from the IBM Maximo wiki page trying to organize and simplify the […]
This entry is part of the Maximo Java Development series. In this article I will describe how to call Maximo business objects methods remotely using a Java RMI connection. This technique can be useful to integrate Maximo in custom applications written in Java or to perform a particular processing of data stored in Maximo database […]
In some cases you need a JDBC connection to directly access Maximo database in order to perform some job. This is not common since all Maximo data can be accessed through standard MboSets. However, you may need to access non-Maximo tables, perform specific SQL statements or bypass Mbos for performance reasons. The two main approaches […]
On almost every application Maximo provides a useful entry in the action menu to duplicate the selected record. When this action is performed, some of the field are intentionally wiped from Maximo. For example if you try to dupicate an Asset you will notice that Maximo resets some fields like ASSETNUM, LOCATION and SERIALNUM.It may […]
This entry is part of the Maximo Java Development series. Sometimes you have to implement some complex logic in workflows or escalation and you feel limited by the out-of-the-box Maximo actions. In these cases you can unleash the Java power and code your algorithm in a custom action class.In order to create a custom action class, you […]
