Before you upgrade the SARA Server software, run the Doctor Report. Refer to the 
DBDS Utilities Version 6.1 Installation Instructions and DNCS Utilities User Guide for 
detailed instructions.  

The Doctor Report provides key system configuration data. 

On a typical system, the Doctor Report takes about 10 minutes to run. 

Follow the procedures in the DBDS Utilities Version 6.1 Installation Instructions and 
DNCS Utilities User Guide to run the Doctor Report. 

Refer to the DBDS Utilities Version 6.1 Installation Instructions and DNCS Utilities User 
Guide for help in interpreting the data generated by the Doctor Report. If you need 
help resolving any issues reported by the Doctor Report, call Cisco Services. 

After you have run and analyzed the Doctor Report, and have corrected any 
problems it may indicate, go to Verify Key Parameters in the Informix Configuration 
File (on page 4). 

Important: Do not proceed with the other procedures necessary to install the 
software until you have run and analyzed the Doctor Report, and you have 
corrected any problems it may indicate. 

 

Before you upgrade the SARA Server software, verify that the TAPEDEV and 
LTAPEDEV parameters are set correctly in the Informix Configuration file onconfig. 
If these parameters are set incorrectly, you may encounter difficulties during the 
installation. 

On a typical system, it takes about 1 minute to determine the current settings of the 
key parameters TAPEDEV and LTAPEDEV. It takes about 5 minutes to change the 
settings.
