DSPJRN command -Sequence number usage

Hi,                     

I'm a novice programmer in AS400 journaling concepts. I'm facing trouble while 
I try to use journal to get audit info using the DSPJRN command. Actually I'm 
getting many duplicate records in the audit file(audit file is updated 2 hrs 
once with the journal data). My audit program should run 2 hrs once and get the 
record from the journal and put them in the audit file.

To achieve this I've stored MAX( sequence number) in the journal retrieved in a 
dtaara and when the job runs next 2 hrs, it will get the journal entries from 
that sequence number. What will happen if CURCHIAN is used and the sequence 
number is reset? Will that be an issue if I try to use sequence number for 
retrieving the data from journal?



Below is my code snippet:

&FAUDSTRSEQ is available in a *DTAARA.

IF         COND(&FAUDSTRSEQ *EQ 0) THEN(DO)            
DSPJRN     JRN(&PJRNLIB/&FJOURNAL) +                   
             FILE((&PEMC2LIB/*ALL)) RCVRNG(*CURCHAIN) +
             FROMENT(*FIRST) JRNCDE((R)) ENTTYP(*RCD) +
             OUTPUT(*OUTFILE) OUTFILFMT(*TYPE3) +      
             OUTFILE(&PJRNLIB/AUJRNOUT) OUTMBR(*FIRST +
             *ADD) ENTDTALEN(*CALC)                    
MONMSG     MSGID(CPF7062 CPF7054)                      
ENDDO                                                  
                                                       
IF         COND(&FAUDSTRSEQ *NE 0) THEN(DO)            
DSPJRN     JRN(&PJRNLIB/&FJOURNAL) +                   
             FILE((&PEMC2LIB/*ALL)) +                  
             RCVRNG(*CURCHAIN) FROMENT(&FAUDSTRSEQ) +  
             JRNCDE((R)) ENTTYP(*RCD) OUTPUT(*OUTFILE) +
             OUTFILFMT(*TYPE3) +                       
             OUTFILE(&PJRNLIB/AUJRNOUT) OUTMBR(*FIRST +
              *ADD) ENTDTALEN(*CALC) 
 ENDDO                              

Thanks for your time. Pls. help me in getting away with duplicate records. 
Thanks in advance.
