DB2 - Problem description

Problem IC66773 Status: Closed

DB2 ON LINUX: SQLOKADETERMINEKERNELINTEGRITY "INDETERMINABLE
OPERATING SYSTEM" MESSAGE IN DB2DIAG.LOG

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
DB2 on Linux (Redhat or Suse) uses the /etc/issue file during 
db2start to determine the operating system. This file typically 
contains a string like: 
 
"SUSE Linux Enterprise Server 11 (x86_64)" 
 
Some system admistrators may change the /etc/issue file due to 
security concerns and remove that default string. 
 
db2start will then cause the following message in db2diag.log: 
 
2010-02-18-11.18.17.579021+060 E3493E313           LEVEL: Info 
PID     : 27765                TID  : 47311355225152 PROC : 
db2star2 
INSTANCE: db2i07               NODE : 000 
FUNCTION: DB2 UDB, oper system services, 
sqloKADetermineKernelIntegrity, probe:30 
DATA #1 : <preformatted> 
Indeterminable operating system. 
 
Note: This message is informational only and will not effect any 
DB2 server functionality. Nevertheless this APAR was opened 
to implement an alternative way to safely determine the 
operating system.
