Hi,
In an attempt to take older data off line and allow database refreshes to be faster, tablespaces associated with partitioned table data for a given time period was taken off line, leaving only tablespaces that relate to the current time period online. In effect, tablespaces related to 2010 and earlier were taken offline from a table.
There are two issues we face.
1. Without giving a filter on the partition key (the business date) to scan for data greater than the dates in the off lined tablespace partition, we get a ORA-376/ORA-1110 error (data file cannot be read at this time).
2. Materialized views using fast refresh or refresh on commit, will also not work because of the partitions being off line.
Queries directly querying the tables are manageable from an application point of view.
But the materialized views failing to aggregate is a bigger problem.
Any ideas on how we can manage this situation? I know that I can move the partitions to a different table in a tablespace to be taken off line. But if possible, we wanted to solve this without doing a move partition.
Regards,
