This article is being written to bring a few points to everyone's attention related to the FlexNet Libraries complied with PIC( position-independent code) In computing, position-independent code (PIC) or position-independent executable (PIE) is a body of machine code that, being placed somewhere in the primary memory, executes properly regardless of its absolute address. PIC is commonly used for shared libraries, so that the same library code can be loaded in a location in each program address space where it will not overlap any other uses of memory (for example, other shared libraries). Linux Platform Makefile in Linux provided kits already have support for compiling with PIC. There is dedicated section written in the Makefile under element shared_object. The Makefile will build shared object with the command make shared_object. By default, shared object is linked with FNP provided PIC libraries inside the kit.     Windows Platform In the windows platform the dynamic library can be built with command as nmake DLL=1. ...

 GetFulfillmentsQueryRequest/GetFulfillmentPropertiesRequest takes in EntitlementID and returns any FNP licenses on the fulfillment The fulfillmentType parameter in the response can be used to differentiate between CERTIFICATE and TRUSTED STORAGE license. There is no straight forward way to differentiate between a Floating vs Nodelocked, except that the floating licenses will return a license text (if enabled in ResponseConfig) whereas a Nodelocked license does not have a license text. The licenseHost parameter in the response will have the host id details. ... View more

Error Can't make directory /usr/tmp/.flexlm, errno: 2(No such file or directory) Description 1.The certificate codebase is littered with explicit references to temporary file locations ( under "/tmp", "/usr/tmp" & "/var/tmp" ). 2.There is a particular reliance on the existence of "/usr/tmp" which is a bug. 3.The error will be seen only when  /usr/tmp directory is not available in the system. 4.This error can be encountered while starting the lmgrd.

Background 11.17 onwards a new functionality of Message Diagnostic was introduced .These messages are intended used to diagnose technical problems that occur During the debugging process, the diagnostic text is usually communicated among several organizations. Therefore, for consistency and accuracy of support,the text in these messages is in English, as is customary in other software applications. Issue “DPLT: waiting for logger to connect” message overloads the sever log, by logging multiple times and consumes machine space as part of these messages. Workaround To Disable these diagnostic messages if required ,set the below parameters ls_diagnostics_enabled=0 at server side and LM_A_DIAGS_ENABLED=0 at client side   Fix The issue has been fixed in 11.17.1(2020 R3),hence if 11.17 is being used then go ahead and upgrade to 11.17.1     ...

With MAX_CONNECTIONS value set(A), license administrator can set the limit on number of connections(of any type) which can be established with vendor daemon. In case, MAX_CONNECTIONS value set(B), is greater than soft limit(A) on the machine then soft limit value supersedes the MAX_CONNECTIONS value(B). Following code snippet provides the value to vendor daemon on the soft limit : - getrlimit(RLIMIT_NOFILE, &openFdLimit); fdLimit = ( int ) openFdLimit.rlim_cur; Vendor daemon reserves(RU) 30 connections for important FNP utilities(lmreread, lmstat etc.) so to avoid outage while using them. It means if value of A is 100 then number of client connections which can be established with vendor daemon is B(70) = A(100) - 30(RU). In case point 2) is valid then another 30 connections vendor daemon reserves(RV) for itself. In that case, B(40) = A(100) -30(RU) - 30(RV) Value of A cannot be less than 31. Utilities can also use buffer (B) until it is not exhausted. Buffer(RU) will only be used once (B) is exhausted. Vendor daemon functionality keeps increment the counter on every socket connection. Once number of connections exceeding 80% of the threshold limit(B), vendor daemon starts displaying warning messages on every successive socket connection. Once number of connection established with vendor daemon reached to threshold limit(B), further all connection request will be dropped(exception utilities), until some the established connections are dropped. ...
