10g enhancements and some more functionalities.

Version: Oracle Database 10.2.0.1 on Windows2003 Server
Oracle Database 9.2.0.4 on IBM pSeries AIX5L Server


Connecting to rman:

Host #> r man
Rman> connect t ar get /
Rman> connect t ar get dbuser as sysdba/ passwd@TNS
Rman> connect cat al og r man/ pass@TNS
Rman> connect auxi l i ar y dbuser / dbpass@TNS

### interactive mode
Host #> r man t ar get / cat al og r man/ pass@TNS
Host #> r man t ar get / nocat al og

### batch mode
Host #> r man t ar get / cat al og r man/ r man@d cmdf i l e <cmd_f i l e_name> l og
<l og_f i l e_name>

Host #> r man t ar get / @‘ dai l y. r cv’

Rman> r epor t schema

### creating rman catalog
1- Connect t o r man cat al og dat abase wi t h sysdba pr i vi l eges
2- Cr eat e cat al og user wi t h unl i mi t ed quot a and gr ant
r ecover y_cat al og_owner , connect , r esour ce
3- St ar t r man wi t h r ecover y cat al og opt i ons
4- r un “cr eat e cat al og” command i n r man
5- r egi st er t he t ar get dat abase wi t h “r egi st er dat abase” command

### creating pipe interface
Host #> r man pi pe r mpi pe t ar get sys/ <passwor d>@TNS_ALI AS
