How do you break a Monolith into Microservices at Scale? This ebook shows strategies and techniques for building scalable and resilient microservices.

The process of changing work orders status in Maximo involves writing your code and packaging it in a WAR file and then placing that WAR file in the MAXIMO.ear and redeployment of Maximo Asset Management System on BEA Weblogic Server.

Writing Code and Creating a WAR File

Before writing the code, you will need to include the library BusinessObjects.jar  in your project. This jar file is available in Maximo installation folder. Now, we can import the required packages. 

List of the importrequired packages mentioned below:

import psdi.server.MXServer;
import psdi.security.UserInfo;
import psdi.app.workorder.WOSet;
import psdi.app.workorder.WO;


Get an instance of the MXServer class:

MXServer mxServer = MXServer.getMXServer();            
Get UserInfo of any authorized Maximo user
UserInfo userInfo = mxServer.getUserInfo("maxadmin");


Next, you will need to get the WOSet object by passing UserInfoas the parameter. If we pass the userInfo here, some of the users lacking required privileges that returned WOSet will be empty.

WOSet woSet = (WOSet)mxServer.getMboSet("WORKORDER", userInfo);                                                         
Set your where clause for filtering records in woSet
woSet.setUserWhere("WONUM = '1045' ");
Get first WO object from WOSet
WO wo = (WO)woSet.getMbo(0); 


Next, you will need to initialize the variable with the desired work order status

String desiredStatus = "COMP";


Now, you will need to initialize the memo variable, which can be used for adding comments, like the reasons or details of changing the status.

String memo = "";


This method changes the Work Oder status by updating rows in the MAXIMO tables WORKORDER , WOSTATUS , etc.

wo.changeMaxStatus(desiredStatus, mxServer.getDate(), memo);


Next, you will need to ask Maximo to persist your changes:

 woSet.save();


Now, close WOSet  so that memory resources are freed:

woSet.close();


Deploying Your WAR File

When deploying your WAR file, you must place it in the MAXIMO.ear file. To do that, you will extract the MAXIMO.ear file and copy your WAR file in the root directory. You also need to make changes in the application.xml file in the MAXIMO.ear located at MAXIMO.ear\META-INF .

Right above <!-- List of EJB modules --> line in the application.xml,  insert the description of your web module as the following:

<module id="WebModule_SomeUniqueNumbericID">
       <web>
                <web-uri>YourWar.war</web-uri>
                <context-root>/YourWebModuleName</context-root>
       </web>
</module>


After making these changes, you will recreate the MAXIMO.ear file and redeploy it on BEA Weblogic server. These are the methods that we can follow to change the status of the work orders in Maximo using MBOs. 

Conclusion

We can change the status of work orders in Maximo using MBOs by, firstly, writing the code and creating the war file in Maximo.ear. Then, we can employ the Maximo Asset Management System on the BEA Weblogic Server. This is the best solution to solving this problem.
