Hello,

My database is running in ARCHIVELOG mode. I have set parameter log_archive_start to TRUE for automatic archiving of redolog files. It works fine

But sometimes I get error in my ALERT log file saying

ARC0: Failed to archive log# 1 seq# nNumber

or

ARC1: Failed to archive log# 1 seq# nNumber

But I also get

ARC0: Beginning to archive log# 2 seq# 386
Mon Jul 29 16:55:53 2002
Thread 1 advanced to log sequence 388
Current log# 1 seq# 388 mem# 0: D:\ORACLE\ORADATA\ORCL\REDO01.LOG
Mon Jul 29 16:55:53 2002
ARC0: Completed archiving log# 2 seq# 386

and same for ARC1 also

Will anybody let me know ... why my ARCH process fails in between?

1. How do I findout how many ARCH processes are running?
2. How to start multiple ARCH process?


Thanks

Sameer
