This example demonstrates how to crack the DB2 file system when it is full.

This article mainly describes the correct method of cracking when the DB2 file system is full. If you are interested in the actual operations related to the correct method of cracking when the DB2 file system is full, you can view the correct Cracking Method for the DB2 file system that is full. The following describes the specific solution and hope it will help you in your future studies.

Case study:

Create a 20 GB tablespace In the DB2 database of the AIX system. The specific SQL statement is as follows:

 
 

  
  
CREATE REGULAR TABLESPACE HTDC_DATA PAGESIZE 8 K MANAGED BY DATABASE  
  
  
USING ( FILE ’/db2_tag/TABLE_SPACES/HTDC_DATA/HTDC_DATA.dat’ 20G)  
  
  
EXTENTSIZE 16 OVERHEAD 10.67 PREFETCHSIZE 16 TRANSFERRATE 0.04  
  
  
BUFFERPOOL BPHTDC  
  
  
DROPPED TABLE RECOVERY OFF  
 
 

Error code: SQLCODE 0968C

Error message: File System is full. (The File System is full)

Cause: the maximum file size allowed by the current user identity is exceeded.

Solution:

Log on to the AIX Terminal

Telnet IPAddress

Enter System

 
 

  
  
root  
  
  
PassWord  
 
 

Switch user to db2admin

 
 

  
  
su - db2admin  
  
  
PassWord  
 
 

Change the fsize to 100 GB (209715100 bytes)

 
 

  
  
chuser fsize=209715100 db2admin 
 
 

Restart the computer

 
 

  
  
shutdown -Fr 
 
 

Log on to the system again and switch the user to db2admin.

 
 

  
  
su - db2admin  
  
  
PassWord  
  
  
db2start  
  
  
db2  
  
  
connect to HTDC user db2admin using ******  
  
  
CREATE REGULAR TABLESPACE HTDC_DATA PAGESIZE 8 K MANAGED BY DATABASE  
  
  
USING ( FILE ’/db2_tag/TABLE_SPACES/HTDC_DATA/HTDC_DATA.dat’ 20G)  
  
  
EXTENTSIZE 16 OVERHEAD 10.67 PREFETCHSIZE 16 TRANSFERRATE 0.04  
  
  
BUFFERPOOL BPHTDC  
  
  
DROPPED TABLE RECOVERY OFF
