Hi Sam,

 

 

There was a post (Click here) from a user on 9.2.2 that noticed TMM restarted when merging in a class with ~200k lines.

 

 

Since then, there have been some improvements to external data group/class handling:

 

 

CR66389 - 9.4 external class handling improvements

 

 

Large class redefinition and the extremedb process (CR56743) (9.4.1)

 

In this version, if you create a data group with many members, and then later redefine the contents of the data group, you no longer receive an invalid cursor error. Instead, the redefinition process completes successfully.

 

 

b load with external IP class files (CR73983) (9.3.0)

 

Configurations with external IP class files no longer cause the system to reload the configuration file with each b load command if the file has not changed. Now, the system only reloads the configuration file when the file has changed.

 

 

I can't imagine it would be speedy to use findclass against a set of million(s) of records though. Have you tried testing it?
