SCL License 服务采用的是“服务器——客户端”的网络模型，客户端和服务器可以是同一台机器。实际检查时，需要逐一确认：

• SCL 服务器主机正常运行；
• SCL 服务正常启动；
• SCL 可以正常分发 license；
• 图形界面或计算客户端与服务器保持网络连接。

确认 SCL 安装的服务器正常运行，使用终端软件登录服务器，在 SCL 启动的账号或 root 账号中，使用命令：

ps -ef | grep lmgrd

正确的输出应包含 lmgrd 和 snpslmd 两个进程：

$ ps -ef | grep lmgrd
dong    97994  87598  0 15:21 pts/8    00:00:00 grep --color=auto lmgrd
dong   454718      1  0 09:14 ?        00:00:00 ./synopsys/scl/2023.09/linux64/bin/lmgrd -c ./synopsys.txt -l synopsys.log
dong   454720 454718  0 09:14 ?        00:00:03 snpslmd -T mgt 11.16 7 -c :./synopsys.txt: -srv ati5aWK1CcwO9XOUvTc45oUVgDdbmUygwQ3fZh2xHDT0xYNJUmFBPOp6sSSyKAG -daemon_port 6d60 --lmgrd_start 60ac4f85 -vdrestart 0

如果 lmgrd 或 snpslmd 未能正常运行，应尝试重新启动（详见：SCL服务的启动和重启），启动不成功时，检查log文件错误信息。

登录 SCL 服务主机，执行命令：

lmstat -a -c 27020@[my_scl_server] # 注释：[my_scl_server] 应替换为实际的服务器主机名或IP地址

license服务状态和使用情况结果如下：

打开 lmtools 工具，点击 Server Status，点击 Perform Status Enquiry，稍等片刻，下面应该显示 license 状态。

当 SCL 启动不成功或者启动成功但不能获取license时，应该按照具体错误信息排查。参见：SCL服务运行与License获取时的常见错误。

以下是使用 lmstat 检查 license 使用情况的典型输出（中文部分为添加的说明）
