P-33
Considerations—PURGE
ALLOWERRORS [ ON | OFF | num ]
specifies the action if errors occur:
If you omit the ALLOWERRORS clause completely, the default is
ALLOWERRORS OFF. If you specify ALLOWERRORS but do not specify an
option, the default is ALLOWERRORS ON.
If a system error causes a user-defined TMF transaction containing the PURGE
command to be rolled back, execution of the PURGE is terminated regardless of the
ALLOWERRORS setting.
[ NO ] LISTALL
specifies whether you want PURGE to display the name of each dropped object in
the following form:
object-type $volume.subvol.name PURGED
object-type is COLLATION, FILE, INDEX, PROGRAM, SVIEW, PVIEW, or
TABLE.
LISTALL is the default. If you specify NO LISTALL, PURGE suppresses the
display of confirmations.
SHADOWSONLY
specifies that you want to purge shadow labels within qualified-fileset-
list, but not other objects or files. If you omit SHADOWSONLY, PURGE does
not purge shadow labels. SHADOWSONLY is not allowed within a user-defined
TMF transaction.
Considerations—PURGE
•
Authorization and accessibility requirements
PURGE requires authority to purge objects or files being purged and authority to
read and write to all catalogs that describe objects affected by the purge.
To purge an index, you also must be the generalized owner of the underlying table
and all partitions of that table must be available.
To purge a table, all partitions, and all indexes, views, and SQL program files that
depend on the table must be available. When you purge any partition of a table, SQL
also purges all other partitions of the table, all constraints defined on the table, all
indexes that depend on the table, and all views that depend on the table except
dependent shorthand views for which you lack purge authority. SQL invalidates the
latter.
ON Attempt to purge all specified files and objects regardless of how many errors
are encountered
OFF Stop the purge operation after the first error is encountered
num Purge all specified files and objects until the number of errors encountered
exceeds the value of num
