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 . 

Creating a polyline map for mapping shipments out of OTM

 

We had a requirement once to map the shipments out of OTM, but on a different system

Below is how I did it.. It might be of help..

 

 

Retrieve Shipment Stop Related Lat/Lan from OTM

SELECT SS.STOP_NUM,LAT,LON FROM SHIPMENT_STOP SS,
LOCATION LC WHERE SHIPMENT_GID='XXX.1002413'
AND SS.LOCATION_GID=LC.LOCATION_GID ORDER BY SS.STOP_NUM

 

Here’s the Javascript for rendering the Map

 

<script type="text/javascript" src="http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2"></script>

<script type="text/javascript">
var map = null;
function RenderMap()
{
map = new VEMap('MapDiv');
map.SetDashboardSize(VEDashboardSize.Normal);
map.LoadMap(new VELatLong(39.828180,-98.57955),4,'r',false,VEMapMode.Mode2D);
var RouteLayer= new VEShapeLayer();

var shipment1 = new VEShape(VEShapeType.Polyline,
[

new VELatLong(41.8672,-103.6575 ),
new VELatLong(41.8672,-103.6575 ),
new VELatLong(42.8419,-106.2818 )

 
]);
var shipment2 = new VEShape(VEShapeType.Polyline,
[
new VELatLong(33.776864,-84.437599), 
new VELatLong(36.223227,-86.977615) 

]);

shipment1.HideIcon();
shipment1.SetLineColor(new VEColor(0,225,0,1));
shipment1.SetLineWidth(3);

shipment2.HideIcon();
shipment2.SetLineColor(new VEColor(225,0,0,1));
shipment2.SetLineWidth(3);

RouteLayer.AddShape(shipment1);
RouteLayer.AddShape(shipment2);

map.AddShapeLayer(RouteLayer);
}
</script>

Error when unassigning orders from a shipment with a stop level data

 

If we have a multi stop shipment and each stop has refnums or remarks or involved parties, and when you try to unassign the  orders related to one of the stops in between, otm throws error . This will be fixed in Otm 6.2.7

        ** Update, there was data consistency issues after the fix in 6.2.7 (Patch is available), Ask oracle for a Patch

Workaround -

 

1. Manually delete the refnums and other stop level data from shipment before unassigning orders related to the stop

2.change the process to populate the stop level remarks before Tendering the shipment

 

Planning Shipments with Dynamic Pools in OTM

Here’s how Dynamic Pooling works in OTM.

Scenario

 

A Region serviced by Multiple Pools

 

With out Dynamic Pool Option (Default), OTM would select one of Pool A or  Pool B in Selection Order and Try to Build a Shipment From the Pool.

OTM Would not evaluate all the Pool Options .

To handle these scnearios, we can use Dynamic Pool where OTM would evaluate all the matched Pools for a Region

 

To enable Dynamic Pool , set parameters  as below

 

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

Tool to update and add Rate Factors

At one of client implementation, users had a large number of updates to rate factors every week and have a large number of rate factor sources

Here’s a a simple way to update rate factors.   Comment in this post if you need a copy of this ..

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

Sender System Name in OTM Outbound transmissions

 

When OTM sends any outbound communication, it includes the Source System URL. Sometimes this is long and clumsy depending on the installation. (Network and Internal DNS)

In order to change the URL and add a Logical System ID (Like ABC_OTMPROD) , make below changes in glog.properties (custom Section)

 

!remove glog.integration.senderSystemId = $glog.webserver.URL$

glog.integration.senderSystemId=ABC_OTMPROD

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)

Fixing Duplicate MAC Address error on VMWARE

Troubleshooting Error - “MAC Address --- of adapter Ethernet0 is within the reserved address range or Adapter Ethernet0 many not have network connectivity”

 

This error will appear when copy of a VM Image is running in parallel with the original VM and  you chose ‘I Moved it’ when prompted by VMware.

 

Solution

1. Shutdown the VM which has the error.

2. Go to the VM’s (The VM which is generating error) Folder and change the Folder Name .,. (change to any thing)

3. Launch the VMX File and VMware generates the same prompt,  choose “I Copied it”

This will fix the problem
