On each Appliance Backup Utility client, change directory to the destination storage path that you want to test.
If you write diagnostic data to the working directory it can fill up that file system.
To isolate performance problems with backup jobs, you can create files that test outgoing data paths. The test provides the transfer rate from the Appliance Backup Utility to the storage device and does not access any data from the Teradata Database.
-
At the command-line prompt, type:
arcmain
-
Log onto the Teradata Database using the logon user and password you established for the Appliance Backup Utility:
LOGON TDPID/user_name,password;
-
To generate data that will be written to the storage device, type the following:
DIAGNOSTIC ARCHIVE FOR 1 GB, FILE=test_file_name;The test_file_name is the name of the diagnostic output file and must be 8 characters or less. You can also choose a different value of dummy data to generate, for example 100 MB. -
Log off the Teradata Database:
LOGOFF;
The ARC output displays the data rate written per 500 megabytes. For example:
09/22/2010 07:17:18 DIAGNOSTIC DUMP: 500,038,300 BYTES (476.9 MB/sec) 09/22/2010 07:17:18 DIAGNOSTIC DUMP: 1,000,041,632 BYTES (953.7 MB/sec)
