Tar and zip at same time - for hot backup

[diwakar]

Hi all,

I have a requirement like this :

Iam creating a tar file and append files to the tar file for backup.

I need to zip the file at the same time.

I can do something like this :
------------------------------------------------------------------------
(AG8)/data/oracle/AG8: tar cvEf /data/export/temp_ag8/ag8.tar control01.dbf
a control01.dbf 2072K

Iam adding one more file to this tar file:

(AG8)/data/oracle/AG8: tar uvEf /data/export/temp_ag8/ag8.tar control02.dbf
a control02.dbf 2072K

-----------------------------------------------------------------------

but when I try to do this - not possible:

(AG8)/data/oracle/AG8: tar cvEf - /data/oracle/AG8/usersAG801.dbf|gzip>/data/export/temp_ag8/ag8.tar.gz
a /data/oracle/AG8/usersAG801.dbf 10248K

Iam adding one more file to this tar file:

(AG8)/data/oracle/AG8: tar uvEf - /data/oracle/AG8/users2AG801.dbf|gzip>/data/export/temp_ag8/ag8.tar.gz
tar: can only create standard output archives.
(AG8)/data/oracle/AG8:



----------------------------------------------------------------------

But I need to append files to a TAR file and zip at the same time, for hot backup, for datafiles in every tablespace one by one .
Iam executing the backup from a procedure and putting all the datafiles in a tablespace into a cursor and tar'ing the files.

Kindly share your ideas for this issue.
