Dell Avamar for Oracle 19.10 User Guide

A backup or restore fails with one of the following error messages:

avoracle Error <6629>: INTERNAL: Unable to send CTL message
(n=-1, retcode=1, errno=0)
avoracle Error <6629>: INTERNAL: Unable to send CTL message
(n=-1, retcode=3, errno=0)

These errors can occur when you allocate too many channels for a backup or restore from Avamar Administrator.

To resolve this issue, it is recommended to set the number of channels to no more than two times the number of processors. If the problem still persists, reduce the number of channels.

The Number of RMAN Channels option is available from the Backup Command Line Options, Restore Command Line Options, and New Dataset dialog boxes.

This problem does not apply to backups or restores started by an RMAN script.
