DB2 - Problem description

Problem IC74846 Status: Closed

THE INSTANCE MAY CRASH WHEN TRYING TO ADD A TABLE SPACE CONTAINER THAT HAS
BEEN USED PREVIOUSLY BY THE SAME DATABASE

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
When attempting to add a table space using a file or path 
container, and the container has previously been used by the 
same database, the instance may crash a similar stack as below: 
 
 
0      sqlbDMSAddContainerRequest 
1      sqlbDMSCreatePool 
2      sqlbSetupPool 
3      sqlbCreatePool 
4      sqldPoolCreate 
5      sqlrlcts 
6      sqlnq_create_tablespace_end 
7      sqlnq_create_tablespace_stmt 
8      sqlnp_smactn 
9      sqlnp_parser 
10      sqlnp_main 
 
This happens when the user attempts to use either a path 
containing a stale container tag file (SQLNAM.TAG), or a file 
container that has previously been used by the database, but is 
not in use any longer (for example old tablespace container 
restored from a filesystem backup).

Local Fix:
For path containers, remove the old tag file (SQLTAG.NAM). For 
file containers, avoid using old container files containing a 
stale tag. Use a brand new file instead.
