Concurrent Operations

Most VRC operations can occur simultaneously by different users within the VRC server. However, there are certain operations that cannot run concurrently.

VRC concurrent operations constraints include:

The following VRC operations cannot occur simultaneously:

Because the following operations require serialized access to staging tables, they are semi-concurrent with the Commit operation:

If you receive an error message that an operation cannot be executed because it cannot be initialized, wait a few moments and try again. VRC might be waiting for an operation to complete, or that operation must be in the initialized state before you can execute another operation.

If you are executing an operation for a scope that overlaps with another user, your operation request fails. If there is no scope overlap, your operation request is queued and executed when server resources become available.

Note: If you are using a Cisco IE2100 device for automating the deployment and management of network devices, your concurrent operation issues might be different.
