HOST command in Forms9.0.4 versions with 10g

Hi,
We are currently running forms6i(character based) on a unix m/c . While trying to upgrade to forms9i (web based) , we find that the HOST command used to call shell script is not wrking and also it doen't shows any errors during compilation or runtime ..Pls suggest how to use HOST command in 9i web based to call a shell script.
Would appreciate an early response..
Thanks and regrds ,
Pooja

Hi Arun ,
Thanks for ur response . But when i use client_host , i m getting compile time error as Client_host must be declared . I m using the command as client_host('/ics/users/ics/test.sh') , where test.sh is the script i want to execute . In our developer suite , there is a forms folder which in turn contains webutil folder ..Am i suppose to put shell script there so that it can be called from there ?
Pls suggest me as how to go abt it..
Thanks n Regards ,
Pooja

SQLPLUS HOST Command Not Supported

Hi,
I am facing strange problem. I have lots of scripts where I have used the HOST command from within SQLPLUS.
Now, on Windows Server 3000 Standard Edition, Version 5.2, I find that both HOST and its equivalent $, both are not supported when used with SQLPLUS on Oracle 10g Enterprise Edition.
Please HELP, and suggest some alternative.
Prashant

There is no such thing as Windows Server 3000. The latest product appears to be Windows Server 2008.
I'm not sure what the version of the Oracle database has to do with it. This is about SQL*Plus and you still haven't told us what version of that you are using. For example:

SQL> host cd

SQL>This is sqlplus.exe (never sqlplusw.exe) version 11.1.0.6.0 on Windows XP Pro 2002 SP3. It's not the best example because SQL*Plus and the database are at the same version - they are often different. For example:
/Users/williamr: sqlplus william/x@//vm.starbase.local:1521/eleven

I'm also a bit puzzled by the error message "Command not success." That doesn't sound like an Oracle command - apart from being vague and ungrammatical it doesn't start with the standard "SP2-nnnn" prefix, for example:

HOST command malfunction

In a Forms 5.0 program I need to take the filenames of all files included in a folder having a specific extension. I choosed to use HOST command to create a text file with these files (dir *.xxx /b > filename.txt) and later read this file using TEXT_IO package. But propably HOST command can't create a new file in filesystem (command prompt window return "File creation error").
Is there a way to take the filenames alternatively? Is something wrong with command syndax and HOST can't create the file? (Have in mind that the same command operates perfectly when I run it manualy in Command prompt)

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by FAISAL SHEIKH ([email protected]):
My guess is that the string in the host command is not correct. Is the filename static or dynamic? <HR></BLOCKQUOTE>
I don't think so because the same command operates well when I give it in a command line window. The file is static.

Host command on linux with forms 10g

Dear Experts
i have one major problem as i have made a form in forms 10g to upload .dmp files copied in application server my problem is that when i excute host command like bellow
cmdln := './imp.sh'
host(cmdln)
to excute and run shell script saved on application server which runs an imp command to upload all files copied in specified location but nothing is happening when i click on button as these command are fired on when button click trigger plzzz help its urgent
were i can make mistake

Whoa...please don't use txt speak when posting here; it is very hard to read and right now it took me about 5 minutes to understand what you have written. Please write proper sentences; help us to help you ; )
It is a good idea to have exact the same verison of exp / imp then your database version; Forms 10.1.2.0.2 would be compatible with a 10.1 database. If your database is e.g. 10.2 you'd need to install the 10.2 client software on your application server anyway. You wouldn't need to care about this when using datapump.
And another thing regarding datapump: conventional export is deprecated in 11.2 so one day or another your customers will need to move to datapump; the sooner the better.
As said: try to run your script on the shell without forms and see if this works. You would see error messages generated by your shell script too.

WEBUTIL problems importing a file with the HOST command.

We are investigating a problem where the users are trying to import a file in from the webserver to be used by the application. The users have successfully moved the file from their local PC to the application server. But, when we perform a HOST command to have the form moved to the UNIX directory, the form hangs. The very last statement of the .BAT file used in the HOST command does the move of the file. And, we can see the entire file in the UNIX directory, we just don't get return back to the form.
I added displays before and after the HOST command in the form. I see the display before the command but don't receive anything after. The weird thing is this is only happening in our development server. The same issue is not happening in production. Also, if I run the form in client server mode, it works fine also. So, it has to be something on the development application server.
If anyone has any advice, I would appreciate their help.
Thanks.

On the server (assuming Windows since you mention a batch file), locate the Oracle Process Manager Service (for mid tier) on the MS Services Console. Open the properties for this service and click on the "Log on" tab. Check the box labeled "Allow service to interact with desktop".
That said, if you are executing a batch file on the Windows server to transfer another file to a Unix machine, the above likely won't work either. This is because Windows will not allow a service permission to access network resources (for security purposes). In this case, rather than the above, you will need to change the same setting so a real domain user and not the "Local System" account.

Printing with host command

Let me explain my situation.
I have a txt file which I want to print out. I usually do this with host command which looks something like this:
command:='print /D:\\print_server\printer file.txt';
The problem is how to print this file in landscape.
If this iAS would be installed on Unix platform I guess my host command would look something like this:
command:='lp -d printer -olandscape file.txt';
the problem is, my iAS is installed on WIN2000 server.
any ideas........

OK I managed to solve this problem with some dosprint.exe program (40$) which can accept various other parameters as well and one of them is also landscape.
oh, that windows again .....

Creating folder dynamically with host command or any solution?

I am working on storing BFILES against thier record. I need to know that how can i perform following tasks if i use host command or any other way if i can do this.
1. As there can be many categories agaist which i need to store files, first i need a separate folder for each category, I am looking for some solution that whenever any user creats new category then against that categoy a folder must be auto created.
2. when i insert records against any category then files should be stored in their specific directory.
I hope It will clear to readers that whta i am looking for.
I am using forms 10.1.2.3, on XP SP-3, WEBUTIL CONFIGURED.
Regards
Naveed

I already made the changes in webutil file, but if you can please tell that does it Support UNC path,
I changed webutil.cfg as follow
transfer.appsrv.write.1=c:\temp,\\sermachine\test
transfer.appsrv.read.1=c:\temp,\\sermachine\test
but when i run the form i got following error,
WUC-8: Server side logging was requested but no log file was specified - logging is disables
Now i don't know that what should I change to work it with on UNC path.
Thanks in Advance.

Trouble with Host command and Plink

Hi all, the sentece
HOST('path -pw 111111 root@ip pwd', NO_SCREEN);
works fine from the command line but it hangs from the Forms Builder
¿what's wrong?
Thank you

yes paul it is possible,
presently we are using same logic by passing form's session ID to the script.
as we already have that session ID available as long as form is active. but,
it would benefit me more for my application,if that happens in reverse fashion.
reason being, we wanted to imitate the same logic once used in our old 2.5 application. but i don't think it is same with 10g, as database server is different from applicaiton server.
thanks

Issues with host command

Hi All
We are running Forms 10gR2 under linux. We are having issues with the host command. We use host command to call ProC* modules in the appsvr. It used to work in Forms 6i. Host commnd no longer works in forms10g. Do we need to any setup to run commands using host.
We need to resolve this issue immediately.
any help is appreciated.
Rgds
Arvind Balaraman

Arvind has said the command needs to run on the app server so HOST is correct, not CLIENT_HOST.
I noticed when I installed 10g (on solaris) that the default.env file has a setting for PATH which does not include /usr/bin so HOST would not be able to find standard unix commands, so I added it in:
PATH=/usr/bin:/home/oracle/product/AS101202/bin
Alternatively you could include the full path on any unix commands run by HOST.
Surpisingly I have not seen this documented anywhere. Could this be the problem ?
I have a related problem I have not solved yet. I have one particular HOST command which works OK until after I run reports from forms, then it just stops working without producing any error.

Forms HOST command no longer works after database upgrade from 10g to 11g

Hi,
After upgrading the database 10g to 11g the forms HOST command no longer works on Unix server. The form used to work fine prior the upgrade. I read all the threads I could find and did not see any solutions. Adding PATH and LD_LIBRARY_PATH does not work because it does not even run a basic shell script. (I saw this solution, adding PATH and LD_LIBRARY_PATH, in many questions / threads).
1. I wouldn't expect the database upgrade to be an issue, but it is the only change we had.
2. Note, 11g is Oracle Fusion Middleware which is quite a bit different than 10g.
I even tried the most basic commands like "echo" which is a build-in Unix command and there is no directory for it (ie. no /usr/bin - so variable PATH is irrelvent). i.e HOST('echo hi'); and HOST('echo "hi" '); and even HOST ('echo hi > /my_file.txt'); all returns FORMS_FAILURE (actually the if is IF FORM_SUCCESS THEN ... else ... and the else part always runs now - whereas it didn't before.).
Or basic commands like /usr/bin/ls as in HOST(/usr/bin/ls). At that point I was just testing the Unix command would return FORM_SUCCESS even though I could not see the results (because they weren't writing to a log file). Notice that I'm using the direct path /usr/bin so no Unix environment variables were needed.
The form does use webutil but that part works. For example, we have webutil_file_transfer( ....) The file shows up on the application server and in the expected directory.
Here's the main goal. Upload a file from clients local PC to the datebase server. The form uploads the file to the Application server, then we have a Unix script to scp (secure copy) the file from the application server to the database server. IF webutil, or any other Oracle functions could put the file on the database server that would be better. But, I don't know of any procedures that do that - or would have done it cleanly (i.e. storing to database and write back to server and then using a blob etc. )
Anyway, I was hoping someone would help with either of these.
1) Get the HOST command to work. - If we can get that to work then I wouldn't need any more help. We can just call the already existing Unix script to copy the file from the application server to the database.
2) OR be able to upload directly to the database server - wanted to do that originally
Any help would be appreciated

Solution for those interested and for anyone else searching this forum for a solution
I found this on My Oracle Support:
<h3>Host Command from Forms Not Working in 11g in Sun Solaris Sparc OS [ID 1157346.1]</h3>
Applies To: Oracle Forms - Version 11.1.1.1.0 and later
Sun SPARC Sun OS
Symptoms:
When trying to execute a Shell script or any OS command using the host() Built-in from Forms 11g, the host()command is not getting executed. The same functionality works on other operating systems and in previous versions like 10gR2.
Steps to be followed:
1) Take a backup and edit the $DOMAIN_HOME/config/fmwconfig/servers/WLS_FORMS/applications/formsapp_11.1.1/config/default.env or any custom environment file.
2) Locate the following environment variable:
LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
3) Comment out this variable. After the changes, it will look like the following:
#LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
3) a) Instead of LD_PRELOAD, kindly use LD_PRELOAD_64 as given below :
LD_PRELOAD_64=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
(This makes HOST AND RUN_REPORT_OBJECT work fine).
4) Save the file and execute your forms. The Host() built-in will work as expected
The LD_PRELOAD setting in default.env is only required for the working of signal chaining facility in JVM version 1.5 and later. If you are not using theSignal chaining facility, this variable is not required. For more information, refer to the following documentation
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14772/forms.htm#CJAJGAFF

HOST command and Forms 4.5

We were using HOST command(to start SQL Plus) in one of the form of our application (forms version 4.5) and this application was running fine on Win NT. Now this application is moved onto Windows 2000. Now we noticed that once the HOST command statement is executed, the application goes into hang and has to terminated. We fixed this problem temporarily by putting a message() and pause statement before and after HOST command statement and the application is running fine. I would like a better solution to this problem. If anyone has encountered this kind of problem or any idea, please reply.

Hi, there,
I have the same problem with my program. Have you figured it out the solution? and if not, could you show me the code of your temporary fix? my email is: [email protected]

Calling SQL Loader from Forms 4.5 using HOST command in Win2000

One of my forms calls SQL Loader 7.3 using HOST command to load a csv file onto the database(Oracle 7.3) under Windows 2000 platform.
Only after sql loader finishes its operation the control should come to my form i.e. synchronous execution.
As of now its running asynchronously.
Is there any way to make it synchronous. If Not any other work arounds?
Environment Details
Forms [32 Bit] Version 4.5.10.6.0 (Production)
Windows 2000 Operating System
Oracle7 Release 7.3.2.3.2

Forms6i running on W2000, Rdbms 8.1.7
in Forms I added a button TEST,
Trigger when-button-pressed : host('test.bat') ;
in directory .......\frm I added file test.bat :
REM ===============
cd /d C:\........\ldr
pause
sqlldr parfile=test.par
pause
type test.log
pause
exit
REM ================
now, pressing TEST button opens DOS window, telling me what's going on, running sqlldr, finally going back to forms
Are you using NO_PROMPT or NO_SCREEN option of HOST command ?
Had a look at Forms 4.5 manuals, there is no mentioning of (a)synchronously operation in connection with HOST command.

Host command from sqlplus based on a condition

I am on an Oracle 10.2.0.3.0 database running on sun solaris.
Am using my sqlplusw on my windows xp professional to do the below :
SQL> select * from v$version;

CORE 10.2.0.3.0 Production
TNS for Solaris: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
I have 4 variables declared in sqlplus for which I get my values from anonymous pl/sql blocks :
print db1_status;
DB1_STATUS
3
print db2_status;
DB2_STATUS
0
print db3_status;
DB3_STATUS
1
print db4_status;
DB4_STATUS
0
I needed some help with doing this :
Based on the values of each these variables, I wanted to invoke the host command to run stuff like
if db1_status = 3 then
host ...something
if db2_status = 0 then
host ...something
I am looking for a way to do this without creating an external procedure or java stored programs. Are there any?
Thanks

Need to use a batch file (.bat) to utilize SQL Plus while generating the SQL statements within the .bat file.
Example:
Inside SQL Plus
SQL> create table testme (name varchar2(255), value number(5));
Table created.
SQL> insert into testme(name, value) values ('db1_status', 3);
1 row created.
SQL> insert into testme(name, value) values ('db2_status', 0);
1 row created.Create a .bat file (Using test.bat)
test.bat
@echo off
echo select value from testme where name = 'db1_status';>temp.sql
echo exit >> temp.sql
sqlplus -S %2/%3@%1 @temp.sql > result.dat
for /f %%x in ('more result.dat') do set RESULT=%%x
if "%RESULT%" == "3" goto :DB1_STATUS_3
if not "%RESULT%" == "3" goto :DB1_STATUS_NOT_3
goto :EOF
:DB1_STATUS_3
echo db1_status = 3
**ENTER SYS COMMANDS HERE**
goto :EOF
:DB1_STATUS_NOT_3
echo db1_status != 3
**ENTER SYS COMMANDS HERE**
goto :EOF
echo select value from testme where name = 'db2_status';>temp.sql
echo exit >> temp.sql
sqlplus -S %2/%3@%1 @temp.sql > result.dat
for /f %%x in ('more result.dat') do set RESULT=%%x
if "%RESULT%" == "0" goto :DB2_STATUS_0
if not "%RESULT%" == "0" goto :DB2_STATUS_NOT_0
goto :EOF
:DB2_STATUS_0
echo db2_status = 0
**ENTER SYS COMMANDS HERE**
goto :EOF
:DB2_STATUS_NOT_0
echo db2_status != 0
**ENTER SYS COMMANDS HERE**
goto :EOF
:EOF
del temp.sql
del result.dat
@echo onAs you can see, this is a simple if/then which takes the value from a dynamically created SQL file (temp.sql) and uses it do determine the next system commands to execute.
Hope this is what ya needed.

OK. You can try the following:
Login as the Unix user (e.g. oracle) on the pre-upgrade environment and run the following command.
echo $PATH
Repeat the above in the post-upgrade environment and compare the two outputs. Generally, PATH will be set using an environment script called from .profile of the user or it could be directly defined in .profile.
You can check this by examining the .profile after logging in as the OS user (e.g. oracle):
vi ~/.profile #i.e check the .profile in the user's home directory.
It's my best guess, as sometimes the PATH could be added later on (for. e.g by another script). Anyways, give it a try and tell what you find.
