The instructions for enabling security created by my colleague included in the blog entry link below describe the steps necessary to enable application server security including modifications to web.xml files for the associated war modules, updates to system properties,  rebuild/redeployment of the maximo.ear, enabling global security within the WebSphere Administrative Console, and restarting the application servers.   ...

On Oracle database, the default optimizer_mode is ALL_ROWS.  This optimizer_mode is inefficient for Maximo SQL queries, especially users screen response.   Here is an explanation of Oracle optimizer_mode from oracle documentation -- http://docs.oracle.com/database/121/TGSQL/tgsql_influence.htm Relevant information extracted from the above link Best throughput (default) When you set the OPTIMIZER_MODE value to ALL_ROWS , the database uses the least amount of resources necessary to process all rows that the statement accessed. For batch... [More]

A day doesn't go by where I'm not dealing with some LDAP related issue or configuration, whether it be simple file modification, general configuration or complex filtering.  When dealing with these issues I try to document my findings and procedures with as much detail as possible.  Recently I've been working on methods for filtering user records from Tivoli Directory Server and the options we have available.  Looking online there is very little information around this topic, so hopefully this blog will help enlighten...

For testing purpose, you can setup Maximo 7.6 with SSO configuration. There are 3 parts to configure SSO. -  Part 1 : Install DNS (Domain Name System)   Server and AD (Active Directory) Service -  Part 2 : Install Maximo with Middleware -  Part 3 : Configure SSO using SPNEGO     Part 1 :  Install DNS Server and Active Directory. 1. Prepare two physical machines (  you can use 2 VM instances )  having 2012 OS. One for the DNS Server where AD and Maximo will be installed. The other for client... [More]

Every issue investigation requires specific loggers and some related loggers.  This depends on the issue on hand.  I will not go into all the situations in this blog, but I would like to describe what the default logging should be or what should be log level at a steady state.  Too much logging is not useful and difficult to sift through.  When a Maximo production environment is working in an ideal state without any issues then here is the logging settings I recommend. Set all loggers to ERROR level except the maximo root... [More]

Maximo environments using BIRT reporting engine as part of the reporting solution could experience this performance problem.  Maximo adhoc reports (QBR reports) can be saved for future use.  This saving instructs the Maximo reporting engine to refresh the report library cache on the application server (JVM).  The report library cache is cached on all application server for improving the performance.  The report library cache which is a sub-cache of Maximo presentation cache causes the Maximo presentation cache to reload...

Many of you are familiar with the recommendation to deploy the RMI registry file, rmireg.war and have probably seen these two great tech notes below: http://www-01.ibm.com/support/docview.wss?uid=swg21262022 http://www-01.ibm.com/support/docview.wss?uid=swg21598724 However, I understand a lot of you may be wondering how many, where and why for a clustered environment? This blog will look at elaborating on the fundamental concepts explored in the above tech notes and be geared more specifically to how we can achieve the deployment of the RMI in... [More]

Customers from time to time have noticed that the Maximo system stops responding. When the environment is reviewed, the database has locks on SIB related tables.  This is a case where the issue is not primarily because of SIB tables but due to the fact that the SIB tables are the victim of Maximo system freezing and holding locks on the SIB tables. If Maximo integration components are writing to JMS Queues using the database storage, then SIB tables are created and used in the database.  Whenever Maximo writes data or reads data from... [More]

In Maximo, reorder quantity is calculated by this formula:   Order Quantity = [(ROP + 1) –Quantity on Order –Available Balance] Y = Order Quantity / Economic Order Quantity (EOQ) X = Next whole number integer of Y Reorder Quantity = X * EOQ     Let me give an example how it works: 1. Create an testing item and set the Reorder parameters 1.1. Create ITEM1000 in ITEM Master application 1.2. Add ITEM1000 to Storeroom CENTRAL 1.3. Set current balance as 10 1.4. Activate the item in Organization and tick Roll New Status to... [More]
