Minor Update to Maximo Log Analysis Tool

The Maximo Log Analysis Tool from a previous blog entry, has been updated.

It fixes some bugs:

  • Properly handles ordering a log files if they appear in a subdirectory within the zip file.
  • Always allow the user to specify the date format.  

It also adds new functionality:

  • Generates a graph of the total number of MboSets reported in Maximo against memory usage.  This is a cumulative report instead of the per-Mbo breakdown of the other graphs.
The Maximo Log Analysis Tool can be found at:

Database Error Authenticating a WebService Call

My Saturday turned out differently than I had planned.  

A customer was a database error trying to authenticate a webservice call.  The first error message and stack trace was:


BMXAA6714E - The data for the next record in the mboset could not be retrieved for the SQL query select * from maxuser  where loginid = :1. See the log file for more details about the error.

It was followed by this error message:

java.sql.SQLException: ORA-01008: not all variables bound

When using DB2, the stack trace looks like

BMXAA6714E - The data for the next record in the mboset could not be retrieved for the SQL query select * from maxuser  where loginid = :1 for read only. See the log file for more details about the error.

That's a lot of stack traces. I've included them to make this blog entry easier to find in the future. 

So what was the problem? mxe.useAppServerSecurity was 0, mxe.int.allowdefaultlogin was 0, and the webservice call was not passing a MAXAUTH header. This scenario resulted in a null username which triggered the database error. 

In our case, changing mxe.int.allowdefaultlogin was our solution. Changing mxe.useAppServerSecurity or passing a MAXAUTH header would have also worked.

Preventing User Logins

Still Around

I have not written in a long time.  Until early this year, I have been supporting a client still running a highly customized Maximo 7.5.  There were some interesting problems come up, especially as the browsers remove support for Java.  Maximo 7.5 uses Java for Workflow editing and Direct Print.  I didn't think I had much to share as the world moved on to later versions of Maximo.

My new position has me working with Maximo 7.6 and MAS8.  I should have more to write about.

Preventing User Logins

I have recently been working on a problem where I want to prevent users from logging into a Maximo node after startup while some complex initialization takes place within the Maximo JVM.  I want the same behaviour as placing Maximo into Admin Mode without actually doing that.   This snippet of code will do that.

// grab the SECURITY service.
SecurityService securityService = (SecurityService)MaximoHelper.getService("SECURITY");

// disable user logins
((TenantLevelObj)securityService.getAllowNewSessions()).set(Boolean.FALSE);

// do what you want to do without user logins

// enable user logins
((TenantLevelObj)securityService.getAllowNewSessions()).set(Boolean.TRUE);
This will prevent new users from logging in but will not log out users who are currently logged in.
