IBM DS4800存储一套
P560小机HA架构一套
两个数据库资源组平时run在HA架构中的任意一台中，资源组全部使用共享存储由于存储在数据库运行过程中发生了异常宕机，导致两个库存在不同程度的坏块数据库A：

数据库恢复
db2 restore db wcelhisp use tsm taken at 20160408043017
这时数据库处于rollforward-pending state的状态，需要做roll forward 操作：
WSRHISDB:istclhis:/istclhis/cfg >db2 "rollforward db wcelhisp to end of logs and stop overflow log path(/istclhis/arclog/WCELHISP/NODE0000)"
SQL4970N Roll-forward recovery on database "WCELHISP" cannot reach the
specified stop point (end-of-log or point-in-time) because of missing log
file(s) on node(s) "0".

4、ppanledb表数据导出
18912.61 expppanedb.ixf
WSRCELDB:root:/test/20160415 >more exp.sh
#/bin/sh
db2 connect to wcelpptp
db2 "export to /test/20160415/expppanedb.ixf of ixf messages /test/20160415/expppaneldb.log select * from w2.ppaneldb"
WSRCELDB:istclppt:/test/20160415 >tail -f expppaneldb.log
SQL3104N The Export utility is beginning to export data to file
"/test/20160415/expppanedb.ixf".
SQL3105N The Export utility has finished exporting "5381266" rows.
5、数据验证
select count (* ) from W2.PPANELDB
6、空间确认
此次将ppaneldb从tbs8k04迁移至tbs8k05
查看tbs8k05表空间使用情况
空间足够迁移
7、建立新表
SET SCHEMA = 'ISTCLPPT' ;
CREATE TABLE "W2"."PPANELDB160501" (
"CHIPID" CHARACTER(14) NOT NULL ,
......
)
IN "TBS8K05"
INDEX IN "INX8K04" ;
ALTER TABLE "W2"."PPANELDB160501 "
DATA CAPTURE NONE
LOCKSIZE ROW
APPEND OFF
NOT VOLATILE ;
ALTER TABLE "W2"."PPANELDB160501 "
ADD PRIMARY KEY
("CHIPID") ;
GRANT SELECT , INSERT , UPDATE , DELETE ON TABLE "W2"."PPANELDB160501 " TO USER "WC1USR";
GRANT SELECT , INSERT , UPDATE , DELETE ON TABLE "W2"."PPANELDB160501 " TO USER "WC2USR";
8、import数据至新表
WSRCELDB:istclppt:/test/20160415 >more imp.sh
#/bin/sh
db2 connect to wcelpptp
db2 "import from /test/20160415/expppanedb.ixf of ixf commitcount 10000 messages /test/20160415/imp.log replace into w2.PPANELDB160501"
nohup ./imp.sh&
导入过程中实时查看archivelog空间使用率，如满了则进行tsm归档
WSRCELDB:root:/test/20160415 >df -g |grep istclppt
/dev/istclppt 0.75 0.04 95% 679 7% /istclppt

导入完成
SQL3110N The utility has completed processing. "5381266" rows were read from
the input file.
SQL3221W ...Begin COMMIT WORK. Input Record Count = "5381266".
SQL3222W ...COMMIT of any database changes was successful.
SQL3149N "5381266" rows were processed from the input file. "5381266" rows
were successfully inserted into the table. "0" rows were rejected.
9、新表创建index
SET SCHEMA = 'ISTCLPPT' ;
CREATE INDEX "W2"."160501_INDEX1"
ON "W2"."PPANELDB160501"
( "CASETID" ASC )
DISALLOW REVERSE SCANS ;
......
10、删除view，rename原表，rename index
DROP VIEW W2.VPPANELDB;
DROP VIEW W2.VPPANELDB2;
RENAME TABLE W2.PPANELDB TO PPANELDBOLD;
rename indexes
RENAME INDEX W2.PPANELDB_INDEX1 TO OLD_INDEX1;
......
11、新表rename，index rename
RENAME TABLE W2.PPANELDB160501 TO PPANELDB;
rename indexes
RENAME INDEX "W2"."160501_INDEX1" TO PPANELDB_INDEX1 ;
......
12、重建view的DDL
SET SCHEMA = W2;
SET CURRENT PATH = "SYSIBM","SYSFUN","SYSPROC","WC1USR" ;
CREATE VIEW W2.VPPANELDB AS
SELECT ...) ;
SET SCHEMA = 'ISTCLPPT' ;
GRANT CONTROL ON TABLE "W2"."VPPANELDB" TO USER "ISTCLPPT" ;
GRANT SELECT , INSERT , UPDATE , DELETE ON TABLE "W2"."VPPANELDB" TO USER "ISTCLPPT" WITH GRANT OPTION ;
SET SCHEMA = ISTCLPPT;
SET CURRENT PATH = "SYSIBM","SYSFUN","SYSPROC","ISTCLPPT" ;
create view w2.vppaneldb2 as
select a.lt_outboxid, b.DPNGRP_ID, b.dpartno, dec(a.pnl_chpbod) pnl_chpbod
from w2.ppaneldb a, w2.ppngrp_dpn_ary b, w2.ppngrp c
where c.MASK_FLG = 'Y' and b.DPNGRP_ID = c.DPNGRP_ID and b.dpartno = a.stb_partno;
SET SCHEMA = 'ISTCLPPT' ;
13、runstat新表
db2 runstats on table w2.PPANELDB and indexes all
WSRCELDB:istclppt:/istclppt >db2 "reorGChk update statistics on table w2.PPANELDB"
Doing RUNSTATS ....
Table statistics:

CLUSTERRATIO or normalized CLUSTERFACTOR (F4) will indicate REORG is necessary
for indexes that are not in the same sequence as the base table. When multiple
indexes are defined on a table, one or more indexes may be flagged as needing
REORG. Specify the most important index for REORG sequencing.
Tables defined using the ORGANIZE BY clause and the corresponding dimension
indexes have a '*' suffix to their names. The cardinality of a dimension index
is equal to the Active blocks statistic of the table.--结束END--
