Maxl iferror usage

I think I am going crazy. This maxl statement works fine on unix.
iferror 'errhandler';
When recreated to run on windows I get
ERROR - 1242021 - (1) Syntax error near 'iferror'. (square brackets removed due to message formatting thing)
The remaining maxl statements run.
I have checked the format of the file and I have tried the following combinations.
iferror errhandler; (no quotes)
iferror 'errhandler'; (single quotes)
iferror "'errhandler'"; (single quote, double quote)
iferror \"errhandler\"; (backslash double quote)
iferror "errhandler"; (double quote)
All producing the same error. Can anyone help with this issue?

Hmm, should work.
Look at my code here.
The script is for Windows.
Could you have some crazy Unix-to-DOS CR/LF issue with the script? Have you tried writing a new one in Notepad?
You should be able to run it from your Windows client if you have the Essbase client installed locally.

Maxl iferror goto does not work

Hi,
I have a vbscript which updates substitution variables in essbase.
But if there is an error, for example, if the variable name is different in essbase than what is defined in the script, the script continues to run.
the only time is actually catches an error is when it encounters the error in the last statement that is executed. i tried to put iferror goto, but it does not work either.
Please help.
Below is a portion of my script.
Thanks.
objOutputStream.writeline("login " & Username & " identified by " & password & " on " & Server &";")
objOutputStream.writeline("spool on to "& logfile &";")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable abcd " & strabcd &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable xyz" & strxyz &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable mnop" & strmnop &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.writeline("spool off;")
objOutputStream.writeline("logout;")
objOutputStream.WriteLine (":Exit")
objOutputStream.writeline("exit;")
objOutputStream.close

Hi,
we work with the exit label as follows:
alter database ...
iferror getmeout;
alter database ...
iferror getmeout...
define label "getmeout";
spool off;
logout;
EXIT;
the spool off and logout command should be part of the defined lable (in your case, too), otherwise you wouldnt logout your session if an error occurs.
Kind regards
André

MaxL error 1241114 - There were errors, look in...

I am running the following MaxL in a batch script on one of our Essbase cubes, which passes the MaxL to ESSMSH.
MaxL:
login admin identified by ******* on *******;
iferror "errorhandler";
spool stdout on to "\\*******\\*******\\Logs\\*******BefLoad.log";
iferror "errorhandler";
spool stderr on to "\\*******\\*******\\Logs\\*******BefLoad.err";
iferror "errorhandler";
set timestamp on;
execute calculation "'FIX(\"*******\",@ICHILDREN(\"*******\")) CLEARDATA \"*******\"; ENDFIX'" on *******.*******;
iferror "errorhandler";
import database *******.******* dimensions from data_file "\\\\*******\\FDMDATA\\*******\\Outbox\\*******.Dat" using server rules_file "L_Data" preserve input data on error append to "\\\\*******\\*******\\Logs\\*******BefLoad.err";
iferror "errorhandler";
logout;
exit 0;
define label "errorhandler";
exit 10;
However, every time the MaxL executes, I have the following single line generated in the "\\*******\*******\Logs\*******BefLoad.err" file:
WARNING - 1241114 - There were errors, look in \\*******\*******\Logs\*******BefLoad.err.
This error is actually pointing to itself (the .err file), however this is the only line with no further information, and is generated every time the batch script is run, even though the build appears to have worked fine. I have double-checked and there are no errors (or even warnings) in the Essbase application log to suggest anything has gone wrong!
Does anyone please have a suggestion as to why it is being generated? Can we just ignore this error? I have read the following, which points out that data load errors will not be trapped by the MaxL "iferror" statement. However, it would be useful to know why this error is occurring and specifically what is going wrong.
MaxL Error Codes

Hi James -
Your dataload errors are getting spooled to the same file as Essbase is trying to spool the message saying that there were dataload errors. I wouldn't count on that working the way you expect it to, and it's not an approach I have ever used - I'd think keeping the stderr spool separate (i.e. separate files) from the dataload errors makes sense.
My bet is that if you point the two error streams to different files you'll see that there are in fact load errors, they're just getting messed up by the fact that stderr and dataload errors are pointing at the same file.
BTW, I appreciate that you're anonymizing for client confidentiality (amazing how many folks post info that obviously identifies their company and give out server / user names...), but any chance you could use e.g. 'appname', 'dbname' etc rather than *******? Asterisks make my eyes hurt, but more importantly they make the different tokens impossible to distinguish. Cheers!

Maxl - can you use variables in iferror statements

hi guys,
A quick one:
Can you use variables when doing error handling? I assume the answer is yes, but just wanted to make sure.
example:
set app1 = Test;
set app1_db1 = Test;
alter database $app1.$app1_db1 force archive to file "C:\\EssbaseBackup\\$app1\\$app1_db1\\$app1_db1.arc";
iferror 'Bk_$app1.$app1_db1_Error';
define label 'Bk_$app1.$app1_db1_Error';
exit 10;
I am putting error handling into my script and want to double check before I go about making the alterations.
Many thanks,
Russell

You don't need to split the files. Create a Maxl with parameters and then call it in a bat file.
In the bat you can then check for Error.
essmsh -D "%HYP_MONTH_SCRIPTS_DIR%\Maxl_Files\HYP_ESS_Archive.msh" %DECRYPTKEY% Appname1 Dbname1
call :archiveerrcheck
essmsh -D "%HYP_MONTH_SCRIPTS_DIR%\Maxl_Files\HYP_ESS_Archive.msh" %DECRYPTKEY% Appname2 Dbname2
call :archiveerrcheck
archiveerrcheck:
     SET FILE=%MAXLLOG_DIR%\Archive.log

MaxL provisioning to native directory group intermittent

I am running the following MaxL in a batch script. The problem is with the twelfth line ("grant read..."):
login ******* identified by ******* on *******;
iferror "errorhandler";
spool stdout on to '*******\Logs\*******.log';
iferror "errorhandler";
spool stderr on to '*******\Logs\*******.err';
iferror "errorhandler";
set timestamp on;
create or replace application ******* as *******;
iferror "errorhandler";
alter database *******.******* rename to *******;
iferror "errorhandler";
grant read on database *******.******* to Group1;
iferror "errorhandler";
spool off;
define label "errorhandler";
logout;
exit;
Sometimes it works, sometimes it gives the following error:
ERROR - 1051013 - User/group Group1 does not exist.
I can confirm that the group deinitely exists in the Native Directory of Hyperion Shared Services, and I have to log in to HSS after it fails and provision the cube manually instead. The strange thing is that the problem is so intermittent.
Should I be running an additional command here? Such as "alter application enable connects" or something similar? Can anyone please suggest why this is occasionally failing? We are using Essbase 11.1.2.1

Does anyone please have any thoughts on this?
Another strange point on this - once the script fails, if I try to run the same MaxL "grant" command in the EAS Console MaxL Script Editor several minutes later, the same error can be seen here too.
I will open an SR with Oracle.

Using MaxL in batch script to get Essbase database size before proceeding

I have a batch script which dynamically generates some MaxL before passing it to ESSMSH. I would like to insert a command at the beginning of the MaxL script, to get and assess the size of the database before proceeding. If the database is empty I would like the script to quit. This is to prevent the script from exporting data and overwriting the previous export file if the database is empty.
The generated MaxL (modified) is currently as follows. What logic can I add to the MaxL script, to assess the database size and go to the "errorhandler" label if it is empty? Is this even possible?
login %USER% identified by %PASS% on %SERVER%;
iferror "errorhandler";
/* log file */
spool stdout on to '<directory>.log';
iferror "errorhandler";
/* error file */
spool stderr on to '<directory>.err';
iferror "errorhandler";
/* export data */
set timestamp on;
execute calculation %APP%.%DB%.C_Export;
iferror "errorhandler";
/* reset database */
alter database %APP%.%DB% reset data;
iferror "errorhandler";
/* import data */
import database %APP%.%DB% data from server data_file "<filename>.txt" on error abort;
iferror "errorhandler";
/* calculate database */
execute calculation default on %APP%.%DB%;
iferror "errorhandler";
/* error handler */
spool off;
define label "errorhandler";
logout;
exit;

Hi Stuart,
Yes I was aware of display database "app"."db"; however this will output a table rather than a specific value. And what logic can I then add to the MaxL script to assess the specific value of "Db Status" and go to the "errorhandler" label if it is empty?
It would seem this needs to be done via a VBScript, to loop through the file rows to find the value before proceeding accordingly. But I was hoping there might be a way to do this within MaxL.

MaxL Error Codes

Hi,
We have many MaxL scripts to load, calculate, export databases etc.... The client wants more precise error messages in the emails the scripts send out to help them decipher what the problem may be in case of a WARNING or ERROR. Is there a list of all possible error codes MaxL would create in the .log? Here's an example of one that is created by changing a member name in source file to make it fail.
WARNING - 1241114 - There were errors, look in C:\Automation\Dev\Logs\Revenue\revload.err.
I'm trying to avoid having to think of every possible type of failure and making it fail on purpose to capture these errors. Was hoping there is a list of all that I could reference?

There are two kinds of errors in MaxL -- command errors and errors that Essbase passes back.
The Essbase data load error you've identified is of the latter type and is not going to get trapped by MaxL's iferror. Unfortunately.
For errors that MaxL can trap (I bet you know the below, but there is something new in 11.1.2.x that's worth reviewing) there are now unique error codes which, I suppose, is what you don't want to do, but it's still an interesting function.
Check out this for a general overview of branching on error:
http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_tech_ref/maxl_commands_errs.html
And of course there's the new Exit function that allows you to pass an error code:
http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_tech_ref/frameset.htm?maxl_commands_exit.html
^^^That's pretty cool and I need to write up a blog post on it, to teach myself to use it if nothing else.

Error handling with Maxl

Could someone post an example of how they handle errors with a Maxl script. For instance, is there a something similar to the IFERROR in Esscmd? Thanks,Rob

If you run Maxl from within a perl script, use can test for errors and then, if you encounter one, decide what you need to next. This gives a lot more flexibility than an IFERROR or On Error statement.Jerry

Error handling from MAXL into a batch file

Hello all
I need to know how do we pass a value to a batch file from MAXL script if an error occurs.
I have used the following in my MAXL to catch an error.
========================
login username password on server01;
Iferror 'error';
Define Label 'error';
Exit;
=======================
In the batch file I used:
If %errorlevel% NEQ 0 goto catch
:catch
echo an error occurred during MAXL script
Exit
========================
This doesnt give me any error even the login info is wrong in the MAXL script
Please correct if this is wrong and provide any help if possible
Thanks in advance

Here's the error checking code I used in my last not-DOS-but-we-call-it-that script:
REM Call MaxL script with parameters
REM The 2>&1 at the end of the below line merges CMD's STDERR into STDOUT
%hyperion_home%\products\essbase\essbaseclient\bin\essmsh.exe %batAutomation%\%esbAppName%\MaxL\%mshScriptName%.msh %esbUsername% %esbPassword% %esbServer% %esbAppName% %mshScriptName% %batDrive% %batAutomation% >>%log% 2>&1
REM Test for MaxL execution errors
IF NOT %ERRORLEVEL% == 0 (SET errormsg=Error! - MaxL script %mshScriptName%.msh failed with ERRORLEVEL %ERRORLEVEL% & GOTO ERROR)The 2>&1 command at the end of the MaxL script line merges STDOUT and STDERR into an overall log file I used for other processes as well as MaxL. It's great for that purpose, but unfortunately logs the username and password -- this would be overcome by encrypting those values. It was acceptable for the solution so I didn't lose any sleep over it.

If you see the last line - it just halts - doesn't show any error or any other message. And the task in the windows task scheduler keeps showing the task as running - without any error there as well.
Any ideas on why it is just going to a limbo (no sessions also appear on EAS console)
Ankur

Yes the script can be manually executed. Also if I again put a mxl file starting from the step where it last stopped - it continues execution normally. (i.e. executes StepB2 as well and continues executing)
And today's execution result - I kept monitoring the server, it ran for 3hrs and then halts after around 80% of the steps with 20% were still remaining. I created a new Mxl to start from the last 20% and it ran successfully again.

Issue with MAXL resource_usage statement

Hi,
I am tring to use the resource usage command in MAXL and I am getting error.
MAXL> alter database SUNDDD.SUNDDD initialize load_buffer with buffer_id 1 resource_usage .5;
ERROR - 1242021 - (1) Syntax error near ['resource_usage'].
I am unable to find the description of the Error Message.
Can someone please guide me as to what the issue is. We are using ASO cube.
Thanks
S

I never used resource_usage with my ASO MAXL scripts. I looked at the documentation of Ver. 7.1.6 & System 9 but couldn't find the definition.
Now I am really interested to know what source you are using for this definition.

Maxl Backup Script

Verion 9.3.1
It seems that when using "export database" and the database in active use, the export fails. Is this correct?
In the beginning of the script, we use "alter system" to kill request, loggout sessions with force and disable disconnect. It seems that if the database is in active use, these commands fail and the essadmin user (system account) never gets logged off. So users can continue to do things.
This is problematic because if my data export fails, we later do a database restructure (clear data) and load the backup file back. Obviously if the export fails and the database is cleared, we are left with a database with no data. Ouch.
I doubt there is a way in Maxl to put a Planning app in maintenance mode so what are the best approaches? essadmin is the system admin which runs the maxl batch but as users are navigating form and such essadmin makes all the connections to Essbase.
It also seems we could use an iferror to just stop the script if it runs in to any errors.
Thanks,
Greg

Greg,
You need to push planning application into maintenance mode or stop planning server -- to stop users logging/entering data through forms
If you have single planning app or all apps can go down during nightly process then just stop planning server by calling stopplanning.cmd( not sure about file name)
after you nightly process is done call startplanning.cmd
If you have multiple applications and only a subset of them needs to be under maintenance mode
then you need to change few values in your application Relational repository ( its not recommended by Oracle)
LOGIN_LEVEL='0' - For all Users
LOGIN_LEVEL='2' - For Administrators
you need to change Login_level value to '2' to move app into maintenance mode..
this link will give you a better idea http://www.orahyplabs.com/2011/02/place-planning-under-maintenance-mode.html
just add above mentioned steps based on your requirement

Maxl command that differentiates ASO and BSO?

I want to differentiate between the ASO and BSO db in Essbase(9.3.1) using some MAXL command.
Do we have some MAXL command that shows the property of Databases?
I was hoping to use the command
execute aggregate selection on database ASOSamp.Sample
This command gives an error when run on a BSO.
Ex:
*[admin/localhost]execute aggregate selection on database Sample.Basic
Execution Message:
MaxL requires an aggregate storage application for this operation.*
I was wondering if Maxl generates a return code for this. If it does, how can I capture this return code?

To give a vague answer, you could run the command in your maxl script and use an iferror statement. It will not tell to the error number but that the command failed.

MaxL error tracking

Hi, could you advise me if there is a way to execute a oracle package from a Maxl.
We have a oracle procedure mxl_status(process_name, status, error_message). our theme is to embed this procedure in the batch/maxl script so that if the Essbase dimension build/data load process fails, the essbase error code with description will be stored in the table used by the procedure. Any way to capture the error message only to variables and pass this to the oracle procedures is appreciated.
Thanks
Subbu

RS,
When I say, you cannot capture error message in MAXL, it does not mean that you have no means of doing it. You can prestore the error codes and messages in a 2 column table and refer it while running the stored procedure.. Check for Message.txt file in $ARBORPATH/api/include, if you installed API with Essbase..The error code that MaxL returns is going to get reset by the next process. So you're probably going to need an iferror statement to branch to exit to trap the error code externally.
Also, there are different kinds of errors as far as OS trapping is concerned. A bad password on login will throw a 1051293 (which is the actual Essbase error code) to %ERRORLEVEL%, but bad data in a data load that results in rejected records -- not an error, and a 0 to %ERRORLEVEL%.
Personally, I would trap the existence of STDERR. That will capture all errors -- the big ones that show up in %ERRORLEVEL% and the minor but still important ones like data got rejected. You will get both the error code and the description from that.
Here's an example of myprocess.err:
ERROR - 103 - Unexpected Essbase error 1051293.
ERROR - 1051293 - Login fails due to invalid login credentials.
To your point -- execute the MaxL script in DOS/Bourne/Korn/VBScript/whatever, check for the existance of the error file and it's contents, have another non-MaxL process pick it up and write its contents to a table. And then of course do whatever you want based on the error.
I always enjoy this stuff -- I don't know why. Maybe because it's because I think once, do it, and never worry about it again.
Regards,
Cameron Lackpour
P.S. As I'm on the ODI bandwagon -- you could do all of the above in an ODI package and it would likely (once you got over the ODI learning curve) be far faster than coding it in a scripting language.

Maxl/esscmds on unix : hiccups

im kinda doubtful if the environment variables have to be set in the script if the path is already set in the .profile in essbase.should i set the server ,user and password for eg :server =xyzexport server etc i also feel i have a problem with setting the user as changes are not reflecting in the root.also what is the best way to create a maxl or an esscmd script in unix for scheduling.

This is an excerpt from a script to enable logins after a nightly archive process:############################################################# Backup the old enable log file and start a new log file. #############################################################mv ${LOG_PATH}/${DB_NAME}_enable.log ${LOG_PATH}/${DB_NAME}_enable.log.bak >${LOG_PATH}/${DB_NAME}_enable.logESSCMD << end_esscmdOUTPUT 1 "${LOG_PATH}/${DB_NAME}_enable.log"IFERROR "quit_scr";LOGIN "${SERVER}" "${USER_ID}" "${USER_PWD}";IFERROR "quit_scr";ENABLELOGIN "${APP_NAME}";:quit_screxit;end_esscmd################################################### Log a message if the script fails at any point ###################################################$COMMON_SCRIPT_PATH/chkstat.sh ${LOG_PATH}/${APP_NAME}_enable.logif [ $? != 0 ]then(and so on)##################################################many of the variables are set in the user's profile as part of the connection, others are set in other places of the script. Because it's Unix, the script doesn't have to have any specific extension, as long as it's been marked as an executable. The syntax here shows how the inline code allows the script to be interpreted and fed to the esscmd processor without creating a separate file.As for scheduling, chron works, other things may work better. That's between you and your support department to work out.Good Luck,-Doug
