My name is Edgar Mengelberg and I have been working with the Maximo and TPAE product suite in various Support roles for over 15 years.
Scheduler (aka Graphical Scheduling or GS) is a great tool that was embedded into core Maximo from version 7502 (prior to this , it was an add-on)
Graphical Assignment (=GA) is also an option in core Maximo Asset Management (MAM) or TPAE that can be used for similar work management and scheduling.
The relationship between GS (Graphical Scheduling) and GA (Graphical Assignment) is that GS is used to find a Craft (Craft as it works at the Craft level, not individual Labor codes) feasible set of schedule dates using the scheduling tools we provide up to an including Optimization.
GA then takes that Craft feasible schedule and this is then used to make assignments to the individual Labor codes.
This can be done manually or with the Labor and Crew Assignment Optimization model.
As with all heavily used core MAM/ TPAE applications or added Industry Solutions, at any point this may well cause some performance issues and so also with the Maximo Scheduler application.
For example your Gantt View could take a long time to open, you may get blank screens ,your applet could take a long time loading or various other signs that Scheduler may not be performing as well as it could.
After a new IFix deployment, or on a new browser, 30 seconds to load the applet will be normal.
Here is my further Top 10 Tips and Tricks you could use 1 by 1 in order to further improve your Scheduler performance ,only if any issues of course, as follows ==>
(1) From Maximo 7508 Ifix007 ,there is APAR IV35491 that was created to assist in Scheduler performance issues. Make sure you have this APAR installed through an Ifix.
If not ,update your IFix level to the the most recent version that can be downloaded from Fix Central.
(2) Check you have a correct JRE version installed.
For example JRE 1.7_51 and 1.7_65 do have known slowness issues for Direct Print , Gantt View and Scheduler as a whole.
(3) )Enable the debug and trace logging as per this article:
This article is an article on how to enable the Java Console logging and how to enable maximum logging, which typically is something you would need when troubleshooting Java Plugin issues.
Please see also the Cache section of this document.
(4) In your System Properties application , check you have a property called mxe.
If not and only applicable when you run a SCCD environment, please add it using these directions:
a. Go To System Configuration -> Platform Configuration -> System
(5) Clear the Java cache.
To clear your Java cache in Windows:
Click Start > Control Panel.
(6) Change the security settings in the Java Control Panel.
In Java Control Panel under "Security" tab --> Try to change the security settings from High to Medium to see if that makes any difference, and possibly, add your server to the Exception site list.
(7) Check if the signed code certificate revocation is enabled.
In Java Control Panel under "Advanced" tab --> Please see if the "Perform signed code certificate revocation check" is set to "Do not check".
(8) Check if the Debugging Java Control options are checked.
Also in Java Control Panel under "Advanced" tab --> Under the "Debugging" option, ensure that ALL 3 of the Debugging section options are checked.
(9) Check if further Java caching is enabled.
In Java Control Panel under "General" tab --> Under the "Temporary Internet Files" option please verify that the Caching is NOT disabled.
(10) Check if any pack.gz files are present in your directory.
If you see any pack.gz files installed, those files should be removed.
