ExternalDrive Bulkplan Performance Issues in OTM

OTM  Version 6.2.*  has a bug that causes tremendous  increase in Bulkplan Runtime when Rate Offerings use ExternalDrive for Transittimes (Like PCMILER).

There is a patch available in metalink . 

Increasing OTM DB Pool size

 

Login to OTM using DBA.Admin

Search for Primary_JTS in Data sources

 

Edit the Pool section of the Source

 

 

You can change the Maximum Capacity as required. 

Note ** : Before changing this value, make sure you have enough capacity and processes limits on Oracle DB

Creating custom queues and Reassigning Topic groups for Performance

 

When you have a huge list of tasks running on the default queues, you might have some backlog / performance problems. In the example  below, we have Allocations running on shipments and is backlog on the default AgentPlanning queue. It will cause other tasks triggered on queue in backlog and has to wait..

 

 

to eliminate these issues, you can create custom queues and reassign the topic workflows to the custom Queue

Here are the property settings to redirect the topic group to custom Queue

 

 

Also remember to set the threads for the new queue

Performance Tuning Options for OTM

 

Typeahead or Autocomplete option in OTM generates lot of sql queries on DB server.

For Example :  in Location Field , if you start typing the first 3 characters, OTM would return list of  matches.

 

What actually happens in the background is OTM generates a query something like this : “ Select location_Xid from location where location_xid like ‘ABC%’ “

Imagine lot of users on the screens trying to fill the fields and OTM generating lot of autocomplete queries wil add lot of queries and load on db server.

Depending on DB Server capacity and connection Pools, this may or may not be an issue..

 

Adjust these glog.properies to manage this option

 

glog.ui.autocomplete=false (To turn off autocomplete )

glog.ui.autocomplete.start=3  ( change this  to a higher value to see performance and adjust as needed)
