- 3. _F_L_E_X_l_m__L_i_c_e_n_s_i_n_g
-
- FLEXlm is perhaps the most popular license manager used in
- the software industry to control the use of software
- products. FLEXlm is best known for its ability to allow
- software licenses to be available (or float) anywhere on a
- network, instead of being tied to specific machines.
- Network licensing benefits both users and license
- administrators. Users can make more efficient use of fewer
- licenses by sharing them on the network. License
- administrators can control who uses the licensed
- application, and the node(s) where the licenses will be
- available. See the _F_L_E_X_l_m _E_n_d _U_s_e_r _M_a_n_u_a_l (in the
- _l_i_c_e_n_s_e__e_o_e._b_o_o_k_s._F_L_E_X_l_m__E_U_M subsystem) for more details
- about the different licensing models supported by FLEXlm.

-
- The FLEXlm licensing software is divided up between a number
- of subsystems. You may need to install different subsystems
- depending on your FLEXlm licensing needs.
-
- If you are using a product which uses FLEXlm node-locked
- software licensing (each license is specific to one node, or
- system), you should not have to install any license_eoe
- subsystems other than the default.
-
-
- 3.2 _F_L_E_X_l_m__N_e_t_w_o_r_k__L_i_c_e_n_s_i_n_g__S_e_r_v_e_r__S_o_f_t_w_a_r_e
-
- If you are using a product which uses FLEXlm network
- software licensing, you will need to install the FLEXlm 4.1
- Server Software (_l_i_c_e_n_s_e__e_o_e._s_w._f_l_e_x_l_m__s_e_r_v_e_r) subsystem.
- This subsystem includes all software for FLEXlm network
- licensing.
-
- The FLEXlm 4.1 Server Software subsystem must be installed
- on the server machine; the subsystem should not be installed
- on client (non-server) machines.
-
-
- 3.3 _C_o_n_f_i_g_u_r_i_n_g__t_h_e__F_L_E_X_l_m__N_e_t_w_o_r_k__L_i_c_e_n_s_e__S_e_r_v_e_r
-
- The license administrator should follow these instructions
- to configure the FLEXlm Network License Server on the chosen
- server machine.
-
- The FLEXlm 4.1 Server Software
- (_l_i_c_e_n_s_e__e_o_e._s_w._f_l_e_x_l_m__s_e_r_v_e_r) subsystem must be installed.

-
- 1. Open a shell window by choosing "Unix Shell" from the
- Desktop toolchest.
-
- 2. Log in as root by typing "su" at the shell prompt.
- Type in the root password if you have one.
-
- 3. Type "chkconfig flexlm on".
-
- 4. Create the server license file. Create a new license
- file in "/_v_a_r/_f_l_e_x_l_m/" and use a text editor (e.g.,
- _j_o_t) to add the network licenses to that file.
-
- Your server license file should include the name of
- the server machine in the name of the file. For
- example, if your server machine is named "control",
- you should create a license file with the name
- "/_v_a_r/_f_l_e_x_l_m/_l_i_c_e_n_s_e__c_o_n_t_r_o_l._d_a_t".
-
- Using the server machine name in the name of the
- license file allows the license file to be copied to
- all client machines without overwriting other license
- files on those machines.
-
- 5. Make sure the new license file is copied to the server
- system and to all client systems of that server. Copy
- your new license file to the "/_v_a_r/_f_l_e_x_l_m/" directory
- of all client systems that will use the license in
- your new file.
-
- 6. Configure the FLEXlm Network License Server daemon to
- use the new license file. Edit the configuration file
- "/_e_t_c/_c_o_n_f_i_g/_l_m_g_r_d._o_p_t_i_o_n_s", using a text editor (such
- as _j_o_t). Change the configuration file to indicate
- the name of your new license file. For example, if
- your new license file is named
- "/_v_a_r/_f_l_e_x_l_m/_l_i_c_e_n_s_e__c_o_n_t_r_o_l._d_a_t", edit
- "/_e_t_c/_c_o_n_f_i_g/_l_m_g_r_d._o_p_t_i_o_n_s" to contain the following:
-
- ----cccc ////vvvvaaaarrrr////fffflllleeeexxxxllllmmmm////lllliiiicccceeeennnnsssseeee____ccccoooonnnnttttrrrroooollll....ddddaaaatttt
-
- 7. Reboot your system.
-
- Alternatively, you can restart the server by hand. To
- stop the server, use the following command:
-
- ////eeeettttcccc////iiiinnnniiiitttt....dddd////fffflllleeeexxxxllllmmmm ssssttttoooopppp
-
- To restart the server, or to start it for the first
- time, use the following command:
-
- ////eeeettttcccc////iiiinnnniiiitttt....dddd////fffflllleeeexxxxllllmmmm ssssttttaaaarrrrtttt

- 8. If you still have problems running applications which
- use FLEXlm network licensing, you can configure the
- FLEXlm Network License Server daemon to write output
- to a log file. The contents of the log file may
- enable you to determine the cause of the problem.
-
- Edit the configuration file
- "/_e_t_c/_c_o_n_f_i_g/_l_m_g_r_d._o_p_t_i_o_n_s" to contain the following:
-
- ----cccc ////vvvvaaaarrrr////fffflllleeeexxxxllllmmmm////lllliiiicccceeeennnnsssseeee____ccccoooonnnnttttrrrroooollll....ddddaaaatttt ----llll ////vvvvaaaarrrr////aaaaddddmmmm////fffflllleeeexxxxllllmmmm....lllloooogggg
-
- Restart the server (as above). You will be able to
- monitor the behavior of the server by looking at the
- file "/_v_a_r/_a_d_m/_f_l_e_x_l_m._l_o_g".
