Before you upgrade the xOD client software, you must update the SAM URL for 

each xOD service to reflect the new software version. This process ensures that your 

DHCTs always have the latest version of the xOD client software. 
Note: You must complete this procedure at least 30 minutes before you begin to 

upgrade the xOD client. 
When a subscriber tunes to an xOD channel, SARA checks the xOD client version 

number that is installed on the DHCT against the xOD client version number that is 

recorded in the SAM. If these version numbers do not match exactly, the DHCT 

attempts to reload the xOD application. 
Important: When you update the SAM URL, make sure you update the version 

number for each xOD service, including those services on TIG channels. 
Complete these steps to update the version number in the SAM URL. 
1  Open an xterm window on the DNCS. 
2  Type doctor –g and press Enter to run the Doctor Report. The Doctor Report is 

generated. 

3  In the Unused SAM URL Check section of the Doctor Report, look to see whether 

your system is at risk of exceeding the allowable bulk.tbl file size. A warning 

message appears if the bulk.tbl file size is greater than 45 KB, and an error 

message appears if the bulk.tbl file size is greater than 55 KB. 
Notes: 

 

The bulk.tbl file is typically less than 45 KB. Therefore, these warning and 

error thresholds have been established to provide you with ample warning 

before a problem with this file is encountered. 

 

For more information about the bulk.tbl file size, refer to Preventing 

Unexpected SAM Server File Errors (part number 4004155). 

Example:  bulk.tbl File Size Threshold Exceeded
