DB2 FOR LUW / DB2FORLUW / A50 - DB2

On little-endian platforms (such as linux), 
the APPL_ID column value of the  CONNMEMUSE_<evmon> event 
monitor table will have an 1 extra garbage character at the end. 
 
This garbage character will usually not be visible if you look 
at the APPL_ID column values, but can be observed if you look at 
the length of the APPL_ID column values. 
 
For example, 
 
---if you create an arbitrary event monitor that includes the 
CONNMEMUSE: 
create event monitor MYEVMON1 for connections write to table 
        CONNHEADER      ( table SP.CONNHEADER_CONN_TO_TABLE in 
UTIL_TSP001 pctdeactivate 100 ), 
        CONN            ( table SP.CONN_CONN_TO_TABLE in 
UTIL_TSP001 pctdeactivate 100 ), 
        CONTROL         ( table SP.CONTROL_CONN_TO_TABLE in 
UTIL_TSP001 pctdeactivate 100 ), 
        CONNMEMUSE      ( table SP.CONNMEMUSE_CONN_TO_TABLE in 
UTIL_TSP001 pctdeactivate 100 ) 
        autostart 
; 
SET EVENT MONITOR CONN_TO_TABLE STATE 1; 
 
---and populate the various tables using some arbitrary 
workload: 
CREATE TABLE GARABGE1 (C1 INT); 
CREATE TABLE GARBAGE2 (C1 INT); 
DROP TABLE GARBAGE1; 
DROP TABLE GARBAGE2; 
FLUSH EVENT MONITOR MYEVMON1; 
 
--- If you try to join the APPL_ID value from CONNMEMUSE_ to the 
control table CONN_, this command incorrectly does not find any 
matches: 
select * from SP.CONNMEMUSE_MYEVMON1 where APPL_ID in 
                                         (select APPL_ID from 
SP.CONN_MYEVMON1) ; 
 
--- However, if you try the same join, but removing the last 
character from the APPL_ID value from CONNMEMUSE,  this command 
successfully returns matches: 
select * from SP.CONNMEMUSE_MYEVMON1 where substr(APPL_ID,1, 
length(APPL_ID)-1) in 
                                    (select APPL_ID from 
SP.CONN_MYEVMON1);

As a temporary work-around, you can subtract 1-byte from the 
APPL_ID, like so: 
 
select * from SP.CONNMEMUSE_MYEVMON1 where substr(APPL_ID,1, 
length(APPL_ID)-1) in 
                                    (select APPL_ID from 
SP.CONN_MYEVMON1); 
 
This work-around will break after the APAR fix has been applied.
