RE: switch logfile vs. archive log current

Switching archive logs will only switch redo logs and change the status of the file that was used to "need archiving". Archive log current, on the other hand, will switch logs and archive any logs that needs archiving.

In my hot backup script, should I be using "alter system archive log current;"
instead of "alter system switch logfile;"?

At present this is what I am doing:

For each tablespace:

sqlplus internal << EOF
alter tablespace ERGO_USR begin backup;
exit
EOF
#

cp $DIR3/ERGO_USR.dbf $BACKUP_DIR$DIR3
#

sqlplus internal << EOF
alter tablespace ERGO_USR end backup;
alter system switch logfile;
exit
EOF For the last tablespace:

sqlplus internal << EOF
alter tablespace USERS begin backup;
exit
EOF
#

cp $DIR1/users01.dbf $BACKUP_DIR$DIR1
#

sqlplus internal << EOF
alter tablespace USERS end backup;
alter database backup controlfile to '$BACKUP_DIR$DIR1/control01.bak'; alter system switch logfile;
exit
EOF
#

Thanks,
