Re: Viewing kernels, semaphore sets and shared memory

[rob@xxxxxxxxx]

To dump shared memory and semaphores use the following command: 

CALL PGM(QP0ZIPCS) PARM('-Emsa') 

As far as I can tell the tool to clean them up manually is not documented 
for customers.  Sorry!  I would stick to iSeries Navigator for that or the 
attached tool. 




Steps to load the dltdomsmem tool on your system: 

1.  Detach the file below to c: 
2. FTP in Binary mode the above file from your PC to the iSeries (to the 
save file created above) by entering the following commands at a Windows 
command prompt: 
        cd c:\ 
        ftp  iSeriesSystem 
        Log in with iSeries user id and password 
        cd / 
        cd  qsys.lib/qgpl.lib 
        bin 
        put  dltdomsmem.savf 
3.  Restore the DLTDOMSMEM library by entering the following command at an 
i5/OS command line: 
        RSTLIB DLTDOMSMEM *SAVF SAVF(QGPL/DLTDOMSMEM) 


When the server is down, do the following: 
1.   ADDLIBLE DLTDOMSMEM 

2.  Verify if there are any orphaned memory segments by entering the 
command: 
        DLTDOMSMEM ServerName FRC(*NO) DLT(*NO) 

3.  You should now have a spooled file with contents similar to the 
example below.  If you have an IDs in the list, you have orphaned memory 
due to the crash. 

 Partition number is:   02                                            The 
partition number associated with the server specified 
 Force value is:  N FRC parameter value 
 Do the delete is:  N DLT parameter value 
 Library is:  QTEMP                                                    Lib 
where the output of the QP0ZIPCS is copied to so it can be processed 
 File is:  DOMSTUFF 
 Mbr is:   DOMSHMEM 
 Per partition value is: X'0800'                                  The 
range values per partition 
 Range of Keys that could be deleted:  0XF8001000 - 0XF80017FF  Based on 
above info, and partition number, the shared memory key range to be 
deleted

Finished finding shared memory, but no deletion for partnumb: 02 


4.   If you had an orphaned memory, remove it now with the command: 
        DLTDOMSMEM ServerName FRC(*NO) DLT(*YES)
