Frequently used DB2 commands (2)

Catalog Database:
Catalog INDIRECT:DB2 Catalog Database On/db2sys[dir_name]
Catalog REMOTE:DB2 catalog Database as at node    Case:        DB2 catalog TCPIP node Nodesun remote 192.168.1.1 server 50000 ostype Aix        DB2 Catalog db sundb as SUN at node Nodesun
Uncatalog Database:
DB2 Uncatalog Database

The best way to view your local database:
DB2 List DB directory On/db2sys[dir_name]

To change the DB2 archive path:
DB2 Update DB CFG for CMSDB using LOGARCHMETH1 disk:/home/db2inst1/archlog

query DB2 under schema:
DB2 "SELECT * FROM Sysibm.sysschemata"

DB2 table Space Extension (Join container):
DB2 "Alter tablespace USERSPACE1 Add (file '/db2data/db2inst1/cmsdb/db2data/userspacefs01/c00000006. LRG ' 114688) "



db2 when doing a migration recovery, from 32-bit to 64-bit instances.

Need to do the following:
1, the source-side instance needs to be upgraded to 64-bit by using the DB2IUPDT command
root>./db2iupdt-w db2inst1
2, the source-side database is cold prepared
3, Change the source-side DB instance to 32-bit
Root>./db2iupdt-w db2inst1
4, transfer the backup to the target
5, restore on the target side, and upgrade the database
DB2 Migrade DB sundb

After the migration of the database, a large number of I/O waits occurred, and the analysis was caused by a small buffer pool setting in the DB2 database. Here's a case for querying and changing the buffer pool:
DB2 connect to SUNDB
DB2 "select Bpname,npages from Sysibm.sysbufferpools"
DB2 "Alter Bufferpool IBMDEFAULTBP immediate size 10000"

set up a federated database query (similar to Oracle Dblink): DB2 update dbm CFG using Federated Yesdb2stopdb2start
