lmflex problem

[staleks]

Hi all,

I am new to Your product and I am following Your documentation FLEXnet Licensing (v11.6.1.0 build 66138 i86_n3).

I have problems with part when I need to start lmflex.exe file from Command line.

I've completed everything without a problem till that moment. I've started Server, and when I enquiry from LMTOOLS I got:

--------
Status
--------
Flexible License Manager status on Mon 7/20/2009 17:38

[Detecting lmgrd processes...]
License server status: 27000@astoisavljevic
License file(s) on astoisavljevic: D:\FLEXnet LM\i86_n3\counted.lic:

astoisavljevic: license server UP (MASTER) v11.6

Vendor daemon status (on astoisavljevic):

demo: UP v11.6
Feature usage info:

Users of f1: (Total of 4 licenses issued; Total of 0 licenses in use)

but when I try to start lmflex.exe in command line
I am getting:

D:\FLEXnet LM\i86_n3>lmflex
lc_flexinit failed: 20

Do You have any idea what is the reason ?

[RobertDickau]

The return value 20 from lc_flexinit means that the FLEXnet Licensing service hasn't been installed. There are a few ways to install it, the easiest (for testing) probably being to run:

installanchorservice.exe Sample lmflex

The C function reference and the trusted storage programming and reference guide have more information.

Hi,

thank You for Your quick answer but i found solution for previous problem.
I didn't have admin privileges on my local WinXP machine so I delivered
FlexNet to Linux OpenSUSE machine where at tje end my web application should run. There I managed to go through Starting and Stoping FlexNET LM and tried lmflex app supplied as example. It works.

Now I want to add demo license to my application. I am using Java implementation.

So what I accomplished till now ?

Step 1) Installed FLEXnet Licensing Toolkit for Java 11.6.1.0

Step 2) Created lmpubkey.h using lmnewgen -pubkey

Step 3) Copied machind\lm_code.h, i86_n3\lmpubkey.h and i86_n3\lmseeds.h to java folder in FLEXnet Licensing Toolkit for Java 11.6.1.0

Step 4) Started vendorInfo.bat that produced demoInfo.java

Step 5) Created Java project, added BasicExample.java, ConnDataExample.java and demoInfo.java.

And when I try to start application at getVendorInfo() method on

Invalid FLEXlm key data supplied (-44,7004)

What I am doing wrong ???

Can some help me about this ?

[RobertDickau]

Hmmm... The fact that getVendorKeys and getCroKeys in demoInfo.java both return zeroes is a problem. Do your demo keys in lm_code.h have nonzero VENDOR_KEY and TRL_KEY values? You will need TRL keys to use the FLEXnet Java API...

[staleks]

I just copied lm_code.h from i86_n3 as suggested in demo.

Here is lm_code.h that demoInfo.java is generated upon:

I believe you'll need to contact Acresso sales to get demo (evaluation) VENDOR_KEY and TRL_KEY values for lm_code.h. There are evaluation and contact links on the FLEXnet Publisher page here: http://www.acresso.com/products/fnp/flexnet-publisher-overview.htm.
