Status: Closed |
"QUIESCE TABLESPACES FOR TABLE <TABLE_NAME> RESET" FAILS TO RESET TABLESPACE STATE |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
The problem occurs when using the QUIESCE TABLESPACES FOR TABLE
command to quiesce a tablespace that has already been quiesced
for a different table using a compatible mode. Once in the
state the "QUIESCE TABLESPACES FOR TABLE <TABLE_NAME> RESET", if
run in a certain order, may return successfully without actually
resetting the tablespace state. |

| Local Fix: |
1. Issue the "GET SNAPSHOT FOR TABLESPACES ON <databaseName>"
command and to determine the tablespace and object IDs of the
tables for which the tablespace is quiesced along with the
authorization ID used to quiesce the tablespace.
Example output from "GET SNAPSHOT FOR TABLESPACES ON
<databaseName>"
...
Tablespace name = TS1
Tablespace ID = 3
Tablespace Type = Database managed
space
...
Tablespace State = 0x'00000001'
Detailed explanation:
Quiesced: SHARE
...
Number of quiescers = 2
Quiescer authorization ID = ZTOTH
Quiescer agent ID = 7
Quiescer tablespace ID = 3
Quiescer object ID = 4
Quiesce state = 1
Quiescer authorization ID = ZTOTH
Quiescer agent ID = 7
Quiescer tablespace ID = 3
Quiescer object ID = 5
Quiesce state = 1
...
2. Query the SysCat.Tables catalogue table to determine the
table names from the tablespace and object IDs.
Examples:
SELECT TabSchema,TabName FROM SysCat.Tables WHERE TbSpaceID=3
AND TableID=4
and
SELECT TabSchema,TabName FROM SysCat.Tables WHERE TbSpaceID=3
AND TableID=5
Result: The tables are ZTOTH.T1 and ZTOTH.T2.
3. Using the authorization ID in the "GET SNAPSHOT FOR
TABLESPACES ON <databaseName>" output, connect to the database
and issue "QUIESCE TABLESPACES FOR TABLE <TableName> RESET" for
each of the tables.
4. Due to the bug this APAR is fixing, at least one of the
"QUIESCE TABLESPACES FOR TABLE <TableName> RESET" will work, but
possibly not all of them on the first try, so repeat steps 1 and
3 until the tablespace is no longer quiesced, or simply repeat
step 3 X times where X is the number of quiescers displayed in
the "GET SNAPSHOT FOR TABLESPACES ON <databaseName>" output. |
