WIP

Table of Contents Previous Section Next Section IMS Info, Summary Overview of IMS Queues

You can look at lots of useful information about the IMS Message Queue, including the amount of free space, by going into ESMAC, choosing IMS in the combobox on the left hand side and then going to the Control page.

From there you can press a pushbutton that Displays the Summary Overview of IMS Queues. You will see the amount of free space in the Free Space Array. The following is an example.


Free space array:  2,048 (Block number: Maximum number of free segments if less than max) --------------------------------
     0:113     20:252     25:161     33: 89     34: 29     35: 26     36: 20     37:  1     38:  2     39:  0
    40:  3     41:  0     42:  3     43:  1     44:  1     45:  3     46: 16     47: 17     48:  1     49: 29
    50: 49     51: 18     52: 42     53: 25     54: 27     55: 41     56: 16     57: 17     58: 44     59: 81
    60: 35     61:190     62:133

This message queue has 2048 64K blocks allocated. Blocks 39 and 41 are full. Another 31 blocks are partially used. The rest of the message queue is unused and available.

Table of Contents Previous Section Next Section Housekeeping

During the initial stages of an application migration effort jobs may terminate abnormally or will be cancelled and leave files or processes in an incomplete status. This section will focus on the programs and procedures used to correct these conditions.

Table of Contents Previous Section Next Section Housekeeping, Orphaned Processes (Linux)

ES servers can sometimes be left running on machines with the shared memory and semaphores that they utilize when the mfds which they were started from has been shutdown. Four (4) scripts have been created to allow users to tidy up redundant CAS processes and memory allocation when these instances occur. The following tables provide a brief description of the scripts.

Script-Name Description
mfmemclean This can be passed the name of a Server, and will remove all shared memory, semaphore allocations, and message queues relating to it before killing the CAS processes. This should be used when mfds shows no servers started but CAS processes still exist from a previous mfds that has not been shutdown adequately, rather than killing the CAS processes from the command line.
  (e.g. mfmemclean ESDEMO)
mfmemlist This can be passed the name of a server and will list all shared memory, semaphores and message queue allocations relating to it. It can be used to monitor shared memory usage by servers and incorporated into tests.
  (e.g. mfmemlist ESDEMO)
  Table 01: Overview of Scripts to Manage Orphaned Processes

The following two scripts use a COBOL API to extract the id of the message queue to be removed and therefore requires an executable copy of mfmemqlist.int, mfmemqlist40.int and the environment configured to point to a valid COBOL product in order to execute fully. It is also recommended that CODIR is pointing to the same COBOL product used to start the mfds utility when running these scripts.

Script-Name Description
mfmempurge This script will remove semaphores and shared memory that no longer have a valid process attached. This script can be used to clear redundant shared memory and semaphores where the CAS processes have died. The script only removes allocations for the login currently set by the environment variable $LOGNAME. The purge will not affect any currently running servers that still have valid CAS processes running for each shared memory and semaphore allocation.
  (e.g. mfmempurge , then answer y to the warning question)
mfmemtrash Will remove all shared memory, semaphores and message queues relating to your login id. This is to be used when both mfds and the CAS processes relating to a server have been stopped and only the shared memory, semaphores and message queues remain.
  (e.g. mfmemtrash, then answer y to the warning question)
  Table 02: Overview of Scripts to Manage Orphaned Processes

WARNING! memtrash should only be used as a last resort to remove redundant memory segments as there is no recovery process!

Table of Contents Previous Section Next Section Diagnostic Procedures

This section will focus on the trace functions that are available within Enterprise Server and used during the Proof-of-Concept effort.

Table of Contents Previous Section Next Section Micro Focus, CORE_ON_ERROR

The CORE_ON_ERROR function provides "after-the-fact" dump information when a system ABEND (such as a S0C7 or RTS-163) occurs.

The following shows the content of the DIAGNOSE.cfg configuration file that may be used to enable or disable the CORE_ON_ERROR function for a Windows System.

set CORE_ON_ERROR=131
set CORE_FILENAME="core.%p@%t_%d"

The following shows the content of the DIAGNOSE.cfg configuration file that may be used to enable or disable the CORE_ON_ERROR function for a Linux System.

set CORE_ON_ERROR=3
set CORE_FILENAME="core.%p@%t_%d"

Note:  For the Linux environment the CORE_ON_ERROR=3 is not supported. Documentation is incorrect???

The location of the DIAGNOSE.cfg file is defined by using the COBCONFIG_ environment variable. The following is an example.

set COBCONFIG_=$ESROOT\ES\cfg\Diagnose.CFG

Note:  For the Linux environment the COBCONFIG_ is COBCONFIG without the trailing underscore. The following environment variables need to be set to enable CTF.

Table of Contents Previous Section Next Section Micro Focus, Consolidated Trace Facility (CTF)

The Consolidated Trace Facility (CTF) provides the ability to track program execution or program behavior at execution time.

set mftrace.emitter.textfile#location = D:\MFPOC\Sources\work\es\ctflogs

set MFTRACE_CONFIG=$ESROOT\ES\cfg\ctf.cfg

set MFTRACE_LOGS=$ESROOT\ES\ctflogs

For detailed information about the Content of the CTF Configuration File refer to the System Preparation document that is included in this suite of documents.

Table of Contents Previous Section Next Section Upper & Lower Case Dependencies

The chcase script will convert the member name to upper/lower case based on the first letter of the two-character parameter. It will convert the file extension to upper/lower case based on the second letter of the two-character parameter.

chcase UL

Table of Contents Previous Section Next Section Profiler, Run Time Performance of a COBOL Program

The COBOL Profiler is a facility that enables you to obtain detailed statistics on the run-time performance of a COBOL program. The program will need to be compiled with the PROFILE compiler option.

The performance statistics produced using the PROFILE Compiler directive for that run of the program are contained in a file called:

program-name.ipf

To run Profiler on UNIX or Linux, enter a command line of the form:

cobprof filenames directives

for example

cobprof programname.ipf +LIST

To run Profiler on Windows, enter a command line of the form:

profiler filenames directives

for example

profiler programname.ipf +LIST
