Re: Serial Attached SCSI (SAS) disk compared to Fibre Channel
Fred Schmidt pisze: Issued: Error! Unknown document property name. iii Our organisation is considering Serial Attached SCSI (SAS) disks in a Hitachi USP-VM for our mainframe environment instead of the usual Fibre Channel disk. Anyone using SAS disk in the mainframe world? Any comments regarding performance, throughput? Performance does not depend directly on the HDD interface. If you compare the same HDD family with different interfaces - it could make sense. In other cases you try to compare apples and oranges. DASD performance strongly depends on other factors like cache, controllers, external interfaces, etc. Generally I wouldn't expect problems with performance. Last but not least: your question likely comes from plan to cut the costs. In this case I would strongly consier other options, possibly much more cost effective. -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.

Something along this could be used as a way to minimize problems when deleting members. I have never had any problems with this approach. You're lucky. It will also shut the door on jobs that have the data set open, and have done BLDLs, and may subsequently use TTRs that point to trash. How ? The shut the door job is *waiting* for EXCL ENQ (OLD). As I read it, shut the door never completes its wait. So you don't know how many other jobs may have previously allocated the data set SHR, opened it, done BLDLs, and not yet closed it. They are holding TTRs which will point to unpredictable content once you compress (w DISP=SHR). (The STD job is cancelled by the compress job when it's finished.) Yes, a couple of other jobs has opened the pds and if they haven't finished their update it may theoretically cause local corruption in the pds. But I have never experienced that, maybe because of the 30 seconds wait I do before beginning the compress. And of course, this is in a test environment. BTW, the STD is not a problem in this case, the only potential problem is the compress (job). And if You are worried You can always wait until all jobs that may have opened the pds are finished before You start the compress. Then there is no problem anymore regarding the risk ds corruption.

If program A is reading /some/file and program B does a rm on it, what happens? From observed behavior, I think the file doesn't go away until A is done with it. I'm told that: A file's name is an entry in a directory. This name relates to an inode and is usually called a link. An inode is a separate structure on disk. A single inode can be pointed to by many names, even in separate directories, but all in the same filesystem. The inode contains a link count which indicates how many names the file has, in one or more directories. When the link count goes to zero due to an rm (or unlink() function) and the file is not open, then the kernel tells the vfs to delete/release the inode on disk. If the file is open and the link count is zero, then the kernel does not tell the vfs (filesystem) to release the inode until open count goes to zero. During this time (file open, but link count is zero), it is possible to create a new link (directory entry name) for the file and thus restore it. Unix uses shared memory and mutex locks to ensure that files are locked between processes. How was that implemented on z/OS? I don't know, but I'd __guess__ the same way. Perhaps someone in the know will speak up. Again, UNIX does not do this locking, the application does it. Unless you are talking about how the VFS/PFS does it.

Re: Unix systems and Serialization mechanism
I believe the advisory locking is very old hat (i.e. BSD 2, SYSV, etc...), and the more modern/proper way to get a file lock is to use: fcntl(fd, F_GETLK, ...); fcntl(fd, F_SETLK, ...); This is not an 'advisory lock' like flock(), but a lock in the operating/file system. fcntl() should be supported by the underlying file system and is supported across networking (NFSv3 and later, I believe and SMB.)

Re: Unix systems and Serialization mechanism
paulgboul...@aim.com (Paul Gilmartin) writes:
Is there a shell interface to flock()?
Is the lock automatically freed when the requesting process terminates,
for whatever cause?
from flock man page:
NAME
flock - Manage locks from shell scripts
SYNOPSIS
flock [-sxon] [-w timeout] lockfile [-c] command...
flock [-sxon] [-w timeout] lockdir [-c] command...
flock [-sxun] [-w timeout] fd
DESCRIPTION
This utility manages flock(2) locks from within shell scripts or the
command line.
The first and second forms wraps the lock around the executing a
command, in a man-
ner similar to su(1) or newgrp(1). It locks a specified file or
directory, which
is created (assuming appropriate permissions), if it does not already
exist.
The third form is convenient inside shell scripts, and is usually used
the follow-
ing manner:
(
flock -s 200
# ... commands executed under lock ...
) 200/var/lock/mylockfile
The mode used to open the file doesn’t matter to flock; using or
allows the
lockfile to be created if it does not already exist, however, write
permission is
required; using requires that the file already exists but only read
permission is
required.
By default, if the lock cannot be immediately acquired, flock waits
until the lock
is available.
... snip ...
lock is freed when command (or subshell) completes.
possible more than you ever wanted to know ... I have shell script for
morning news reading:
function sqlhq {
# block everybody else until file of previously seen URLs is created
(
flock -x 200
sqllite extraction from browser history file and url reformating
uses exclusive lock
) 200sqlhq.lock
}
# end extracting previous URLs from browser sqlite history file
#-
# wget retrieve and convert news page URL
function wgethq {
... calls wget to fetch news url web page, then extracts reformats
news item urls in the web page ... news web page processing
done asynchronously
(
flock -s 200
waits until sqlite browser history extraction has finished before
eliminating news item URLs already seen, uses shared lock
once exclusive lock has been released
) 200sqlhq.lock
(
flock -x 300
... does some serialized global processing, one news URL page at a
time; sends active browser each unseen news item URL to be
be opened in separate background tabs (in aggregate can be several
hundred tabs/urls). uses exclusive lock.
) 300x1.lock
}
# end processing of each wget file
#-
... start main shell ... asynchronously start browser history URL extraction
sqlhq
# ansyncronously fetch/proces each news URL page
fn=0
while read url ; do
wgethq f$fn $url
let fn=$fn+1
donehq.list
# wait until everything has completed
wait
... snip ...
hq.list contains a list of 70 or so news webpage URLs from around the
internet.
there is very tiny possibility of race condition ... that sqlhq
asynchronous function doesn't set exclusive lock until after the first
wgethq asynchronous function obtains the shared lock (however,
realistically even if the asynchronous sqlhq function was stalled for
unknown reasons, the ansynchronous wgethq functions do quite a bit of
web operation before attempting to obtain the shared lock).
wgethq function eliminates previously seen news item URL (already in
browser history file) from being sent to the browser for loading. The
global serialization (in wgethq) is for the case where multiple
different news sites might refer to the same news item URL ... so that
it is only sent to the browser for loading once.

ENQ question
At month end a job of ours that nornally runs a few minutes took several hours by lpar saturation. Our job reads a JCL PDS used by the DBAs. They complained because their job and subsequent jobs were held up by hours. And once their job ran it took an hour instead of a minute (no exaggeration!). We have been asked to change our job which would require changing it on at least 6 plexes. Our solution is for them to change their job. They are using a construct that has the followed DD //OUTPUT DD DISP=OLD, DSN=IMS.DBA.JCLLIB(MEMBER) The question I have is: Is the DISP=OLD needed or does the QSAM interface to BPAM handle collisions? I vaguely remember that the MIM product had a feature added to it to handle member collisions in the middle to late 1980's by Ed Legowski so collisions were an issue back then.

Re: ENQ question
There will be others that will provide a more indepth explanation. However, to serialize a dataset DISP=OLD needs to be used. Otherwise you can have multiple users/jobs updating/reading concurrently with the SHR Disposition. If your process uses ISPF Services, then it is less likely because ISPF does the enq. Not knowing specifically the program that is reading this dataset, I am not sure what else might be going on or if MIM/GRS might be helpful. If you have a product like THRUPUT Manager, it can help in isolating file usage through resources. If you have a scheduling product like CA_ESP you can also create the dataset as a resource and serialize it. I am guessing that your process is Lots of jobs are submitted from various groups that will update your IMS.DBA.JCLLIB dataset. Then at some point, you might be closing off the updates so you can run your production batch. Is that close to your process? If so, then I might look to setting up an ISPF process that lets the DBAs indicate which dataset and member needs to be update (the FROM function). It builds a job or table that is then read say once an hour to do the actual update to IMS.DBA.JCLLIB. That way you could reduce the number of random jobs running to a consistant run proces. But that is just a thought. Lizette At month end a job of ours that nornally runs a few minutes took several hours by lpar saturation. Our job reads a JCL PDS used by the DBAs. They complained because their job and subsequent jobs were held up by hours. And once their job ran it took an hour instead of a minute (no exaggeration!). We have been asked to change our job which would require changing it on at least 6 plexes. Our solution is for them to change their job. They are using a construct that has the followed DD //OUTPUT DD DISP=OLD, DSN=IMS.DBA.JCLLIB(MEMBER) The question I have is: Is the DISP=OLD needed or does the QSAM interface to BPAM handle collisions? I vaguely remember that the MIM product had a feature added to it to handle member collisions in the middle to late 1980's by Ed Legowski so collisions were an issue back then.

I know RMM only, so my further comments regard RMM, not CA-1. Will CA-1 let me create handles or aliases in the TMC without actual data sets on the tapes? (My only problem is that testers scan the tapes and complain about undocumented data sets that I use as handles.) If I understand correctly a volume ownership would be sufficient for you. YOUR volumes in RMM are YOURS. You can narrow your searches in various ways. BTW: don't mess user volumes with master volumes Most of my tapes are for testing; they expire in a week or a month and CA-1 nicely scratches them and removes them from the VSAM catalog. If I catalog a handle in the VSAM catalog, would CA-1 be aware of it and uncatalog it when it scratches the tape? I fear not. RMM can scratch the volume because dataset is uncataloged or uncatalog dataset, because the volume goes to scratch. At least one of the options should satisfy your request ;-) Unfortunately, I understand the VSAM catalog is not indexed by volser, so there's no simple way to uncatalog every data set on a specified volume, especially if it's impossible to read their VTOC entries. VSAM catalog??? Do you mean ICF ? VSAM catalogs are dead for approx. 10 years. BTW: you can easily list datasets by the volume in RMM.

I want to thank all of the respondents to this question. I was tied up and could not respond yesterday. It seems certain that IBM changed the call to ENQ in 1.10 so my old SVC filter won't work.

One is unlikely in view of the economic situation that we and most shops face. The other will be political with many unhappy developers who will lose easy access to production data.

IBM has written a utility - ISPF/PDF.The thing is, this has never been documented in the ISPF manuals nor ISPF help that I know of. If you attempt rename a data set that is ENQed / in use from an ISPF 3.4 volser list (not a catalog list) and have the proper RACF authority, you see this message: DATA SET NAME IS IN USE BUT YOU HAVE AUTHORITY TO OVERRIDE THIS TEST *** Then when you hit enter, you get confirmation panel like this: Rename Data Set In Use Command === Data Set Name . : some_data_set_name Volume . . . . : vv The system detected that a data set with the above name is in use (possibly on another system) but it cannot determine whether it is the data set you wish to rename. If it is the same data set and any program has it open, renaming it could cause serious system and data integrity problems. You have the extra security authority to rename the data set even though its name is in use. Refer to the DFSMS documentation on the RENAME macro for further information.

Re: Unix systems and Serialization mechanism
I don't want to provide exact definition of programming language, but JCL hardly fulfills such one. I'll take the word of my programming professors from the mid-1970's. According to them, it is a programming language. Scripting, iteration, and such things as function/subroutine calling are not required. Variable substitution, and the ability to alter control flow (if/then/else, and skipping steps - COND -as weak as it is) is enough to justify it as a programming language.

On 07/02/2010 10:14 AM, Kirk Talman wrote: At month end a job of ours that nornally runs a few minutes took several hours by lpar saturation. Our job reads a JCL PDS used by the DBAs. They complained because their job and subsequent jobs were held up by hours. And once their job ran it took an hour instead of a minute (no exaggeration!). We have been asked to change our job which would require changing it on at least 6 plexes. Our solution is for them to change their job. They are using a construct that has the followed DD //OUTPUT DD DISP=OLD, DSN=IMS.DBA.JCLLIB(MEMBER) The question I have is: Is the DISP=OLD needed or does the QSAM interface to BPAM handle collisions? I vaguely remember that the MIM product had a feature added to it to handle member collisions in the middle to late 1980's by Ed Legowski so collisions were an issue back then. (EDIF maybe) So what is current state of the art? We are 1.10 with 1.11 rolling out this year (it's on 5-10 lpars already). ... If the DBA jobs are the only ones writing to the PDS, and if there is some other mechanism in place that would keep two of their update jobs running in parallel, and if there is a low likelihood of any online updates to the PDS while their jobs are running, then their jobs probably can get by with DISP=SHR. A PDS is protected from damage by concurrent update attempts, but the protection mechanism is to ABEND an attempt to open for OUTPUT if the PDS is already OPEN for output, and the DBA's would probably also be unhappy if that happened and their job blew out of the water. When we've had cases where concurrency with DISP=SHR couldn't be avoided and possible ABEND failure were not acceptable, we have avoided problems by first staging the PDS data to another dataset and then using a follow-on job step to copy the data into the PDS with a utility that uses ISPF SPFEDIT enqueue conventions internally before opening the PDS for OUTPUT. As long as all batch jobs play by the SPFEDIT enqueue rules before opening the PDS for OUTPUT, DISP=SHR is reliable. If either of the above is not possible, then your best bet may be to shorten the window of possible interference by adding an initial job step to your job to copy the needed member(s) to another dataset with an efficient utility that uses minimal resources, so that your enqueue on the PDS can be released as quickly as possible before your actual processing steps begin. -- Joel C.

Re: Is Commuication ECB valid for subtask
:In other words Can the communication ECB be posted in the subtasks as well I wouldn't think so a it is in key0 storage, but as there is bypass code for wait perhaps there is also bypass code for post. The communications ECB is indeed in key 0 storage, but the system recognizes attempts to wait on that specific ECB and treats it as a special case. It allows any task in the address space to wait on the stop/modify ECB. The stop/modify function would not be terribly useful otherwise. Only one task can wait on it.

Re: Unix systems and Serialization mechanism
Mike's definition is certainly close to the concept most I know would associate with a programming language. JCL can control sequencing of program executions, but it is incapable of expressing much in the way of useful computation directly via JCL alone. One could argue that JCL is indeed a programming language, just with very limited capabilities. Since variable manipulation is very constrained and looping capability is totally absent, the subset of functions JCL can compute is a pretty small subset of what is computable. I can visualize approaches one might take to program a Universal Turing Machine in languages like COBOL, Fortran, PL/I, C, Assembly, etc., which suggests by Turing's Thesis that if one had an idealized runtime platform that wasn't constrained by memory or time that in theory these programming languages could compute any computable function. I think is is equally obvious that without a looping construct, implementing a Turing Machine purely in JCL would be totally out of the question. So clearly JCL belongs in a lesser category than those programming languages typically used to implement business algorithms. I may be wrong, but I don't think HTML without embedded java or javascript even has the limited computational capabilities of JCL. If one allows that HTML includes the notion of HTML with java and javascript, then it obviously qualifies as a programming language. If you exclude java/javascript as being part of HTML, then I think one would have to say HTML's capability is to define/describe a structure, not a computation, which would rule it out.

Re: What is a programming language? (WAS Re: Unix systems and Serialization mechanism)
FWIW, it never occurred to me that it *wasn't* a programming language. But when I referred to it as such a few years ago, I got lambasted by some (only some!) of my then-cow-orkers.
