E262: error reading cscope connection 0 - connection

I am using screens for coding using vim and cscope. when I leave the code for about 5 min (I mean go out for coffee etc) and start again. I can't use cscope again. I will get errors like:
E262: error reading cscope connection 0
E257: cstag: tag not found

Try this:
:cs kill 0
:cs add cscope.out
For more help information, use
:help cs

In order to set the changes permanently, you can add those two cs commands in ~/.vimrc text file provided the cscope's default editor is vim.
To set default cscope editor, add the following line in ~/.bashrc
export CSCOPE_EDITOR=vim

Sending IFS File to Outq Prints Line of "#" Symbols

I am attempting to send a file from IFS to an outq on our AS/400 system. Whenever I do, I get exactly what I send, as well as a line of "#" symbols of varying lengths appended to the end.
Here's the command I'm using:
qsh cmd('cat -c /path/test.txt | Rfile -wbQ -c "ovrprtf file(qprint)
outq(*LIBL/ABCD) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)"
qprint')
The contents of test.txt is just Hello World!
The output I get when I send the command is
Hello World!####################################################################
I have not found any posts online about a similar problem, and have tried changing values and looking for additional switches to get it to work. Nothing I'm doing seems to fix the issue.
Is there a command or switch that I am missing, or is something I have in there already causing this?
EDIT:
I found this documentation which is the first time I've seen this issue mentioned, but it's not very helpful:
“Messages for a Take Action command might consist of a long string of "at" symbols (#) in a pop-up message. (The Reflex automation Take Action command, which is configured in situations, does not have this problem.) A resolution for this problem is under construction. This problem might be resolved by the time of the product release. If you see this problem, contact IBM Software Support.”
The only differences are: 1) this is not a pop-up message, it's printed. 2) I don't believe we use Tivoli Monitoring, although I could be wrong.
Assuming we do use Tivoli Monitoring, what would the solution be? There's no additional documentation past that, and I am not a system administrator, so I can't really make the call to IBM Software Support myself. And assuming we DON'T use it, what else could cause this issue?
I get different results, yet similar. I created a test.txt with Windows Explorer, put in Hello, world!, saved it and tried the script. I got gibberish for the 'Hello, world!' and then the line of # symbols.
My system is 7.3 TR5, CCSID 37 (US English) and my IFS file is CCSID 1252 (Windows English). Results did not change if I used a stream file of CCSID 819 (US ASCII).
I didn't have any luck modifying Rfile switches.
I found that removing devtype(*userascii) produced printed output in plain English without the # symbols. Do you really need *USERASCII? I would think that would be more for a pre-formatted 'print-ready' file like Postscript or the like.
EDIT: some more things to try
I don't understand why *USERASCII is adding those # symbols; it looks like a translation issue.
I tried this and still got the extra ###... You might have to play with the TOCCSID() parameter. Although a failure, it did give me an idea: what if those # symbols are EBCDIC spaces being sent as-is to the *USERASCII print stream? All we'd need is a way to send only the number of bytes in the stream file, without any padding.
CRTPF FILE(QTEMP/PRTSTMF) RCDLEN(132)
CPY OBJ('/path/test.txt') TOOBJ('/qsys.lib/qtemp.lib/prtstmf.file/prtstmf.mbr') replace(*yes)
ovrprtf file(qprint) outq(*LIBL/prt3812) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)
cpyf prtstmf qprint
The data in QTEMP/PRTSTMF is in ASCII; DSPPFM shows that much. It also shows a bunch of spaces: after all, it is a fixed length file. My next step was to write an RPG program to read the stream file and print it, but Scott Klement already did that: http://www.scottklement.com/PrtStmf.zip
This works on my system:
ovrprtf file(qsysprt) outq(*LIBL/abcd) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)
prtstmf stmf('/path/test.txt') outq(abcd)

"** exception error: undefined function add:addfunc/0 in Erlang "

I'm trying to execute a simple erlang program of adding two numbers.
I'm trying to do this in Eclipse on Ubuntu 10.04 LTS.
When i execute this program, I'm getting the error as shown below:
** exception error: undefined function add:addfunc/0
How do i go about solving this error? Thanks in advance.
This program when executed in the erlang shell is working fine. But when it comes to eclipse it's giving me this error. Not this, any program for that matter is giving me the similar error. Guess I would be missing something about the eclipse configuration.
EDIT:
Anyways, This is the sample add program,
-module(add).
-export([addfunc/0]).
addfunc() ->
5 + 6.
This message tells you that module add doesn't have an exported function addfunc/0.
Ensure the function you want to be called has exactly that name, doesn't expect any
parameters, is
exported, the module is
compiled, the search path includes the compiled beam file and that there is no module clashes using code:clash()
Update
It's not clear how erlide (eclipse erlang plug-in you seem to use) compiles and runs a program. Try to compile source using erlc or inside erl shell. That way you'll have much easier controllable environment and you'll better understand what's going on.
I got exactly the same problem -for a tail recursive fibonacci function- below:
-module(math2).
-export([fibonacci/1]).
fibonacci(0) -> 0;
fibonacci(1) -> 1;
fibonacci(M) -> fibonacci(M-1) + fibonacci(M-2).
In the end, had realized that this is a compile-time exception. Then, have opened a new tab on my shell and tried with erlc, instead of erl.
$ erlc math2.erl
Now I am also able to see math2.beam file created.
Called fibonacci with 10:
4> math2:fibonacci(10).
55
and it worked!
I think you have not compiled the code and you are trying to run the program.
In eclipse, using the "Run" icon, trigger the run; which will get you to the erl shell in the console window.
There you do -
cd("C:\Learning_ERL\src").
And you should see output like-
(Learning-ERL#DALAKSHM-MNFSM)7> cd("C:\Learning_ERL\src").
c:/Learning_ERL/src
ok
Then compile the code -
c(add)
you should see something like this on the erl shell-
(Learning-ERL#DALAKSHM-MNFSM)10> c(add).
{ok,add}
Now you should be seeing a new file called - add.beam in the same directory as that of your erl source file - add.erl
add.beam is a bytecode file
Now you should be able to run the program without any error
How do you try to execute your code?
In your editor, right-click and choose "Run as"->"Erlang application". The VM that is launched will have your project loaded automatically and when editing/saving a file it will get reloaded. When launching, a console appears and you can call your code from there.
If it still doesn't work, what message do you get for m(add).?

Error "Invalid Locales set !!" when trying to install sqldemo on Informix

I am extremely new to Informix and am having some trouble trying to get sqldemo installed.
Set up so far:
openSuse 12.1 (32 bit)
Informix Growth Edition 11.70 UC6
Informix SQL Developer 7.50 UC6
Informix RDS 7.50 UC6
Informix ID 7.50 UC6
After struggling a few days and a lot of reading of http://publib.boulder.ibm.com/infocenter/idshelp/v117/index.jsp, I managed to get Informix installed and On-line.
I also opted to install the demo database instance that comes with the installation.
I now and attempting to get started with Informix 4GL by Example.
I am trying to get the sqldemo database up. I don't know if it will replace the previous instance installed with Informix, but that is a different problem.
Right now as per the document, running the following should set up the DB:
sqldemo stores2t -log
I however get an error: "Invalid Locales set !!".
I have tried looking up this error and also in the documentation.
I have tried setting the CLIENT_LOCALE and DB_LOCALE in my .profile file.
For example:
export CLIENT_LOCALE=en_US.CP1252 and
export DB_LOCALE=en_US.819
This has not helped.
A push in the right direction, or perhaps some other documentation I could read that would explain things better would really be appreciated.
If any other information is required from me, please do not hesitate to ask.
Update 1
Thanks so much for the response.
A couple of things firstly that I have tried since your post.
Changed the the CLIENT_LOCALE and DB_LOCALE as you specified - Same error - So i removed it as you said it should not be set.
Fixed a problem in my PATH and made sure it has /usr/informix/bin - Same Error
INFORMIXDIR is /usr/informix
INFORMIXSERVER is ol_informix1170 (This is from the database that was installed with the informix install, don't know if this must be changed? and if so to what?)
Ran the script you mentioned, result :
INFORMIXDIR=/usr/informix
INFORMIXSERVER=ol_informix1170
INFORMIXSQLHOSTS=/usr/informix/etc/sqlhosts
LANG=en_US.UTF-8
ONCONFIG=onconfig
I noticed I had set the language to UK, which made the Locales en_gb instead if en_us, so tried changing that in my .profile, which did not help, so also tried changing the language to US and the locales to en_us, but this made no difference.
As for what you said about the sqldemo script and the already installed db, It is fine if that db is removed as this is just a test VB box for me to learn on.
Could the $INFORMIXSERVER set as ol_informix1170 be the problem?
Thank you once again for the help.
Neill
Update 2
Thanks again for the response.
A few things to note.
The dbenv results I posted is all that shows which i assume/presume (uh-oh) means that the other environment variables are not set. Which of the environment variables you posted are absolutely necessary for it to work?
As above, Where would I find the terminfo file, or does this need to be created?
As above, the SQLEXEC variable... where would I find sqlrm? I can somewhat remember from the documents I have read I think it should be $INFORMIXDIR/lib? but I only have an esql directory. Is this correct.
Barring that something in the first 3 above is not causing more problems, when trying your suggestion of DEMOPATH=en_us/0333 sqldemo stores2t -log I receive the following error:
Sorry, cannot read the mkstores3 program required to build the demonstration database. Check the /etc subdirectory of INFORMIXDIR (/usr/informix).
Checking /usr/informix/etc shows indeed that there is no mkstores3 file.
Attempting your further note of isqldemo, I get the following error:
/usr/informix/bin/isqldemo: line 58: /usr/informix/demo/sql/en_us/e01c/isqldemo: No such file or directory.
I guess this makes perfect sense as there is no e01c directory, just the 0333 directory.
Right now anything you can tell me would indeed be a consolation because my newb-ness to generally Linux and definately Informix is a big factor. Interesting that this bug has been around for so long. I guess way more experienced folk than I figured out how solve it on their own, or just never bothered with the sqldemo.
I guess that will teach me to read this:
INFORMIX-4GL by Example
Version 4.1
July 1991
Going to check now if any updated text exists, but would still appreciated more help in solving this problem. Do you think reverting to a previous snapshot before Informix was installed and not opting for the ol_informix1170 database to be included could be a possible solution? I wouldn't really see that it would be, but what do I know.
Many many thanks for your continued time and effort.
Regards,
Neill
Update 3
So I see indeed the document I was reading is ancient. I have found an updated one (2002) which uses a different script (dbaccessdemo7).
I tried running that, have run into an error, but tomorrow is another day.
For now I am going to mark this as solved because of the bug detected and resolved. I am not going to put more time and effort into sqldemo.
Thank you so much, and if I struggle with dbaccessdemo 7, I will post a new question.
Regards,
Neill
The sqldemo script won't create a new server; it may clobber your existing database (a single server may house multiple databases; indeed, there are 4 sys* databases created when a server is initialized) but it won't harm your server otherwise.
Probable cause of the error
The normal problem with invalid locales is that you've not set $INFORMIXDIR. You need $INFORMIXDIR set unless /usr/informix is (a symlink to) the correct location. You also need $INFORMIXSERVER set, and you usually need $INFORMIXDIR/bin on $PATH. Strictly, $INFORMIXSERVER is the only mandatory variable; in practice, you worry about the other two too.
The $INFORMIXDIR setting is used to locate the locale information (which is found in $INFORMIXDIR/gls) and the message files (which are found in $INFORMIXDIR/msg).
Note that CP1252 is a Windows code page. Normally on Unix, you'd either not set CLIENT_LOCALE or DB_LOCALE, or you could set them to:
export CLIENT_LOCALE=en_us.8859-1
export DB_LOCALE=en_us.8859-1
or you can choose another more appropriate (to you) locale. The 8859-15 locale includes the Euro symbol, for example, or the utf-8 locale dictates UTF-8 in the database. But, for initial debugging, stick with the 8859-1 locale, aka 819 or 0333 (all based on the IBM CCSID). If it doesn't work with 8859-1, then we have one set of problems; if it works with 8859-1 but not some other codeset or locale, then we have a different set of problems.
Follow-up info if the solution above fails
If that isn't the trouble, then I'll ask for some more details — notably, your Informix environment as reported by the dbenv script below:
: "#(#)$Id: dbenv.sh,v 2.11 2007/09/02 00:18:58 jleffler Exp $"
#
# Printout INFORMIX database environment
informix1="DB[^=]|DELIMIDENT=|SQL|ONCONFIG|TBCONFIG|INFOR"
informix2="ARC_|CLIENT_LOCALE=|GL_|GLS8BITSYS|CC8BITLEVEL|ESQL|FET_BUF_SIZE="
informix3="INF_ROLE_SEP=|NODEFDAC=|ONCONFIG|OPTCOMPIND|PDQ|PSORT"
informix4="PLCONFIG|SERVER_LOCALE|FGL|C4GL|NE_"
informix5="TCL_LIBRARY|TK_LIBRARY"
informix="$informix1|$informix2|$informix3|$informix4|$informix5"
system="COLLCHAR=|LANG=|LC_|LD_LIBRARY_PATH(_64)?=|PATH=|SHLIB_PATH="
jlss="IXD(32|64)?="
env |
egrep "^($informix|$system|$jlss)" |
sort
It's an old script; that's why the shebang is missing.
Second set of diagnosis
I was hoping for the complete output of the dbenv script; it is surprising how often something shows up. However, given what you've said, it is likely to be OK.
The INFORMIXSERVER setting sounds fine.
I'm struck by the LANG=en_US.UTF-8 setting; Informix does pay attention to $LANG and the $LC_* variables (that's why dbenv prints those out). That may be a factor in the problem. However, I would have expected CLIENT_LOCALE and SERVER_LOCALE to deal with that if it was the problem. Also, on my Mac, I have LANG=en_US.UTF-8 and yet I can connect to (8859-1) databases OK.
This is beginning to look like an install problem...or sqldemo problem...
I transitioned from a Mac to a RHEL 5 (archaic) x86/64 machine, and tried running sqldemo over there:

Invalid Locales set !!
$
Oh yeah? No; my locales are fine, thank you!
Well, so be it...I can reproduce your problem! That's step 1. Step 2 is to look at the expletive deleted script.
PRODUCT=sql
DEMOFILE=sqldemo
DEFLANG=en_US.8859-1
INFORMIXDIR=${INFORMIXDIR:=/usr/informix}
INFENV=$INFORMIXDIR/bin/infenv
CONVLOC=$INFORMIXDIR/bin/convloc
if [ $# -gt 0 -a "X$1" = "X-e" ] ; then
LOCALE=$DEFLANG # -e means en_US.8859-1 required
shift
else
LOCALE=`$INFENV DBLANG` # get DBLANG value
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV CLIENT_LOCALE` # try CLIENT_LOCALE instead
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV DB_LOCALE` # finally default to DB_LOCALE
fi
fi
fi
if [ "x${LOCALE}" = "x" ]; then
LOCALE=$DEFLANG # finally default to DB_LOCALE
fi
export LOCALE
if [ "x${DEMOPATH}" = "x" ]; then
echo "Invalid Locales set !!"
else
exec $INFORMIXDIR/demo/$PRODUCT/$DEMOPATH/$DEMOFILE $*
fi
exit $?
Note that test for ${DEMOPATH}; note that DEMOPATH is not set in the script. So, we've got to get it set. What to? Well, ls $INFORMIXDIR/demo/sql shows that there are various locale-specific sub-directories (en_us,
ja_jp,
ko_kr,
th_th,
zh_cn,
zh_tw) and under the en_us directory there's 0333 (only).
Please run:
DEMOPATH=en_us/0333 sqldemo stores2t -log
This more or less worked for me — I believe it would work for you. I have a slightly unusual setup in that I have just I4GL (p-code and c-code) and ISQL in the $INFORMIXDIR; the server is run out of a different directory. This means I don't have server utility programs like dbload (specifically) in $INFORMIXDIR/bin. When the sqldemo script tried to load the data with dbload, therefore, it failed for me. It would work for you because you have all the Informix software in a single directory. To add insult to injury, it runs the dbload program by explicit path, so I can't futz my PATH to make it available.
This should get you going. I have a bug to report...it is CQ idsdb00244894.
I'm sorry that you ran into so much trouble. You shouldn't have done so.

Lua check if a file is open or not

I'm trying to script a lua file to check if a certain file is open. Then I want it to close that file if it is open. I know how to check if the file exist but I need to know how to check if the file is open, meaning the file is running.
Lua, like C, C++, and pretty much every other language, can only close files that it opens itself. You cannot close files open by other people (not with standard Lua calls); this would be incredibly rude.
So you can't test to see if a file is opened by someone else. Nor can you close their file. There may be system API calls you could make to do this, but you would have to give Lua scripts access to those APIs yourself. Lua's standard libraries can't do this.
Sounds like you want to check which if any programs have a given file open.
first thing that comes to mind is parsing the output of lsof on linux.
fd = io.popen("lsof path/to/my/file")
fileopened = (#fd:read("a*") > 0)
Kind of a hacky way to do it, but it works:
processname = "process_name_here.exe"
filedata = io.popen("tasklist /NH /FO CSV /FI \"IMAGENAME eq "..processname.."\"")
output = filedata:read()
filedata:close()
if output ~= "INFO: No tasks are running which match the specified criteria." then
-- Program is running. Close the program
os.execute("taskkill -im "..processname)
else
-- Program is not running
end
Just make sure to replace "process_name_here.exe" with the process name that shows up in task manager
Alternatively you can just use this to close it without checking if it was actually running:
os.execute("taskkill -im process_name_here.exe")

Using pfccomp or pint to run Pascal-FC programs

I'm using the Pascal FC implementation for Windows Vista found on http://www-users.cs.york.ac.uk/burns/pf.html
I'm trying to run the dining philophers problem found on the link but I don't get how to make the compiler work.
Screenshot
In the screen shot, the program appears to be waiting for you to enter the name of the file to use for the compiler output. Enter a file name.
Better yet, use the pfc.bat command and let it choose the output names for you. The batch file will also run the program automatically after it has been compiled. At the command prompt, run the command like this:
C:\pascalfc-vista> pfc philchan.pas
