SQLDOBJTABINSERTRID, PROBE:1152 - DATABASE MARKED BAD OCCUR AFTER ATTACHING DATA PARTITIONS ON PARTITIONED TABLE. |

DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
As of v9.7, creating partitioned index on a target partitioned
table followed the ATTACHING DATA PARTITIONS/SET INTEGRITY tasks
may cause a logical corruption of object table (SQLD_BADPAGE)
which can incur the DB marked Bad.
The sample of reproducible steps would be like those:
db2 "create regular tablespace ts_data"
db2 "create regular tablespace ts_index"
db2 "create table t1 ( i1 int, i2 int ) partition by range
(i1)"\
"(part part0 starting(1) ending(1) in ts_data index in
ts_index)"
db2 "create index i1_t1 on t1 (i1) not partitioned"
db2 "create table t2 ( i1 int, i2 int ) in ts_data index in
ts_index"
db2 "create index i1_t2 on t2 (i1)"
db2 "alter table t1 attach partition part1 starting 2 ending 2
from t2"
db2 "set integrity for t1 immediate checked"
db2 "create index i2_t1 on t1 (i2) partitioned"
Below info will returned to the command line while creating the
partitioned index, which indicated the DB is marked Bad.
DB21034E The command was processed as an SQL statement because
it was not a
valid Command Line Processor command. During SQL processing it
returned:
SQL1034C The database is damaged. All applications processing
the database
have been stopped. SQLSTATE=58031
A bunch of error messages like below will be found in the
db2diag.log:

The problem happens because creating partitioned index is trying
to use an object ID that is already marked as used on that
related tablespace after attaching a source data partition to it
with set integrity.
Because when attaching a partition to a partitioned table, DB2
will drop any indexes on the source table that are not required
once the table is attached. Under such condition, if DB2 drop
all indexes on the source table, DB2 need to reset the index
object ID in the partition's packed descriptor to zero, however
DB2 were not doing this (So it come to light this new APAR). A
non-zero index object ID in the packed descriptor means that an
index object exists and one of DB2 internal function will use it
later when creating the table's first non-partitioned index. The
code in DB2 internal compontent sees that the index object does
not exist and goes to create the index object with this object
ID and when inserting into the tablespace's object table, this
causes an error and the database is brought down. |

1. If recreating target partitioned table is acceptable:
Export all the data from the target partitioned table, drop the
table and recreate the table, then import the data that was
previously exported.
Then use one of these two workaround to keep from continually
hitting the problem once the table is recreated.
a. Drop all indexes on source table that correspond to "NOT
PARTITIONED" indexes on target table prior to the ATTACH
operation. These indexes will be drop anyway by the ATTACH
operation.
b. Create at least one partitioned index on target table before
the attach.
2. If recreating target partitioned table is not acceptable:
It's required to detach all of the problematic partitions into
standalone tables.
To determine which partitions have the problem below diagnsotic
data is needed as following:
a. db2cat output from the table, which can be gather using the
following command:
db2cat -d BCSSDB -s 'SCHEMA_NAME' -n 'TABLE_NAME' -o
db2cat.out
b. output from the following query:
db2 "select DATAPARTITIONID, DATAPARTITIONNAME from
SYSCAT.DATAPARTITIONS where TABSCHEMA='SCHEMA_NAME' and
TABNAME='TABLE_NAME'"
Then contact the IBM Support Service. |
