RMAN archive backup takes more than 1 hour.

Question

Hello,
We execute the following command from HP Data Protector 5.50 in order to backup archives from an Oracle 8.1.7 database running in HP-UX 11.00:
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=inf,OB2BARLIST=Oracle_Archivers_Inf)';
allocate channel 'dev_1' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=inf,OB2BARLIST=Oracle_Archivers_Inf)';
allocate channel 'dev_2' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=inf,OB2BARLIST=Oracle_Archivers_Inf)';
sql 'alter system switch logfile'
sql 'alter system archive log current'
backup
filesperset 1
format 'Oracle_Archivers_Inf<inf_%s:%t:%p>.dbf'
archivelog until time 'SYSDATE-2'
delete input;
backup
filesperset 1
format 'Oracle_Archivers_Inf<inf_%s:%t:%p>.dbf'
archivelog all;
This process takes more than 2 hours for just 3 GB and we don't think this is network issue.
Is our RMAN command doing more thinks than just archives backup?
Almost at the end of backup we get following message:
Default exp binary /INF/oracle/app/product/8.1.7/bin/exp/ is used for catalog export.
Does this message mean an export is done at the end of archive backup?
Note that message belongs it is more than 2 hours later.
Thanks in advance for your help.
Regards,
Carles

Yes, it appears one of your utilities is doing an export backup, check HP Data Protector settings.
