Element	Purpose	Key Considerations
-v	Verifies a backup If verification is successful, you can restore the storage spaces safely.	Specify onbar -v to verify the backup. You can perform a point-in-time verification. You cannot verify the logical logs. You must specify the -b or -v parameter first. You can verify a whole-system or physical-only backup (IDS).
dbspace_list	Names a list of storage spaces to be backed up or verified	If you enter more than one storage-space name, use a space to separate the names. On XPS, if you enter a dbslice name, it verifies all the dbspaces in that dbslice.
-f filename	Verifies the storage spaces that are listed in the text file whose pathname filename provides Use this option to avoid entering a long list of storage spaces every time that you verify them.	You can use any valid UNIX or Windows pathname and filename. For the format of this file, see Figure 10. The file can list multiple storage spaces per line.
-L level	Specifies the level of backup to verify (XPS): `0` for a complete backup `1` for changes since the last level-0 backup `2` for changes since the last level-1 backup	The archecker utility fully verifies level-0 backups on all database servers and performs limited verification of level-1 and level-2 backups. If you do not specify a level, archecker verifies the level-0 backup.
-q session	Assigns a name to the verify session (XPS)	DBSERVERNAMErandom_number is the default session name. The session name must be unique and can be up to 126 characters. This name appears in the onstat utility so that you can follow the progress of the verify session.
-t time	Specifies the date and time to which dbspaces are verified	How you enter the time depends on your current GLS locale convention. If the GL_DATETIME environment variable is set, you must specify the date and time according to that variable. If the GLS locale is not set, use ANSI-style date format: YYYY-MM-DD HH:MM:SS.
-w	Verifies a whole-system backup	Available on IDS only.
