The next query depends on the usage of an NAS filer. When you are using such an NAS filer and so answer y to this question you have to input the information described in section “Configuring
BACKUP_COMPRESS=true false gzip bzip2
Compression of the database files is controlled via the BACKUP_COMPRESS parameter. It may take the following values:
true
Selecting true for BACKUP_COMPRESS causes the default compression mode
false
No compression is used.
gzip
The GZIP mode is used for compression. In addition a compression level may be selected by setting the (hidden) COMPRESS_LEVEL parameter (see below).
bzip2
The BZIP2 mode is used for compression. In addition a compression level may be selected by setting the (hidden) COMPRESS_LEVEL para- meter (see below).
Now configure_nsrora asks you whether you want to perofrm parallel backups of the tablespaces. Answering y an additional parameter has to be set.
AMON Parameters
Now the amon parameters are queried:
AMON_MAX_LOGS
This parameter defines a threshold value for the maximum number of offline redolog files in the archive directory. When this value is reached, the next poll (see AMON_INTERVALL parameter below) will initiate a backup of these redolog files. When the offline redolog files have been backed up success- fully on external media they are deleted from the archive directory.
AMON_MIN_LOGS
You use this parameter to specify how many offline redolog files should not be backed up but should remain in the archive directory when the threshold value AMON_MAX_LOGS is reached. It is always the newest redolog files that remain in the archive directory without being backed up.
