ASMCMD copy command fails with file open error
I'm trying to copy an external datafile into an ASM storage, with the 'cp' command. The operanting system is Windows, the sorce file is on a network share. The current logged on operating system user has access to the network file. Running the ASMCMD cp command causes error, because the source file on the network can not be opened.
On the file server security event log there is an error with an attempted login with NULL SID. The ASMCMD does not use the current logged on user credentials, but something else (probably SYSTEM).
How can this problem solved, without copying the large source file to the local filesystem? How can we define network credentials for the ASMCMD utility?
