Problems Checking Out Files After Upgrade

Products

• CA Harvest Software Change Manager - OpenMake Meister

Issue/Introduction

After upgrading Harvest, we are seeing random errors and problems when performing checkout operations.  Example errors include:

E02020053 Cannot open signature record for <filename>
E03020566 Cannot write signature record for <filename>
E03020175 Server cannot communicate with the agent on machine <servername>

We also find that when checking out in "synchronize" mode, at times, Harvest will check out all files in the folder, even if there were only one or two files in the package being checked out.

What causes this and how can we resolve the problem?

Environment

CA Harvest SCM all versions

Cause

These types of problems can happen

• If a signature file has become corrupted, 
• If the format of the signature file for the new version of Harvest has changed

Resolution

The difficulty is that no utility or tool exists that can "repair" or "refresh" a signature file.  In such cases, the best solution is to delete the "harvest.sig" file causing the problem and do a fresh checkout.  In this process, Harvest will create a new signature file.
