How to fix DB2 Tablespace OFFLINE state issue?

-

Sometimes we face an error where one (or more) of our db2 tablespaces goes offline caused by loads, DB crashes, abnormal db2 services/or server shutdown, etc. So in this blogpost let us see how can we check which tablespace is in OFFLINE state and bring back tablespace’s state to ONLINE.

 Finding TableSpace State

To check which tablespace is OFFLINE, execute the below command:

SYNTAX:

db2 connect to <database_name>

db2 list tablespaces |egrep -i "ID|Name|State"

db2 list tablespaces show detail

 

If u see Tablespace state with 0x4000, then that tablespace is in Offline state

There are 2 methods to resolve the tablespace from offline to online as below.

Method1:

We can execute below DB2 commands to take off tablespace's OFFLINE state.

 db2 terminate

db2 force application all

db2 connect to <database_name>

 

Method 2: 

Perform ALTER Tablespace command to bring the tablespace up while the rest of the database is still up and deployed.

db2 connect to <database_name> db2 "ALTER TABLESPACE <TablespaceName> SWITCH ONLINE"

Phases of a load operation

-
A complete load operation consists of five distinct phases; they are as follows: Analyze phase Load phase Build phase Delete phase Index copy phase Analyze phase:  This phase of the Load process is only utilized when a column-organized table is being loaded and the column compression dictionaries need to be built. This happens during a LOAD REPLACE operation, a LOAD REPLACE RESETDICTIONARY operation, a LOAD REPLACE RESETDICTIONARYONLY operation, or a LOAD INSERT operation (if the column-organized table is empty). For column-organized tables, this phase is followed by the load, build, and delete phases. The following diagram showcases the steps involved in the analyze phase. The analyze phase is invoked if you are loading data for the first time into a column-organized BLU acceleration table using LOAD INSERT, or running a LOAD REPLACE with RESETDICTIONARY or RESETDICTIONARYONLY clause. Load phase:  During this phase, data is loaded into the table, and index keys and table stat...
