SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: 7.2.000.100
* 3910567 (3892025) Some CP server operations cannot simultaneously handle writes
from multiple clients.


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: 7.2.000.100

* 3910567 (Tracking ID: 3892025)

SYMPTOM:
The CP Server logs errors about operation failures when multiple clients of CP
server run similar commands in parallel. These operation errors are flagged as
CRITICAL.

DESCRIPTION:
When clients of CP servers run multiple commands in parallel, sometimes, such
operations return the value SQLITE_BUSY to the client. The operation returns
SQLITE_BUSY, because another operation has locked the database. In such case
where operation fails due to database lock being busy the server does not retry
these commands.

RESOLUTION:
The VxCPS program is modified to handle a SQLITE_BUSY value and the program
retries the operation on the server.
