Server Administration :: Taking Partitions Offline In Tables
Feb 4, 2012In 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.
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.
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.

Backup & Recovery :: 2 Separate RMAN Backup One Backup Is Of Only Datafile
Jan 24, 2011I have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time
it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)

SQL & PL/SQL :: CLOB Parameters Taking More Time
Mar 3, 2012We are on a GRID DB and using Oracle 11g.
A external reporting application ( SQL SERVER REPORT SERVICES) sends in some comma separated parameter values, which has to be queried against a table with 6-10 million records.
Length of the comma separated value can go upto 5000-6000 in length based on user input in the front end application. This application sends this value in comma separated. i.e., like
'AA1-11101,AA2-34346,AA4-534399,.....' like this at a time the application can send upto 500 values each of length 10. i.e, maximum length can be upto 5000. I used CLOB to handle this because since the length can be 5000 and varchar2 can handle only 4000 long literals.
But the time taken by the CLOB to verify against the table using INSTR is more compared to VARCHAR2.
I found that VARCHAR2 does'nt take much time. Is it a good idea to have VARCHAR2 in the PLSQL procedure as parameter instead of CLOB, since PLSQL VARCHAR2 can handle upto 32000 long values.
