创建代理时，报缓存管理器不能生成端口范围

BIP7175E: The cache manager could not generate a port range.  A list of free ports could not be determined.  The broker configuration has not been changed.
Investigate the port range settings for the cache manager on all other brokers on the system.  
Specify the ports manually by using the '-r' parameter on the mqsicreatebroker or mqsichangebroker command. Alternatively, complete the following steps:  
1. Determine whether one or more brokers are configured to use more ports than necessary.  
2. Adjust those brokers to use a smaller port range, if possible, so that this broker can use them instead.

BIP8081E: An error occurred while processing the command.
An error occurred while the command was running; the command has cleaned up and ended.
Use messages prior to this one to determine the cause of the error.  
Check for some common problems:  
Does the user id have the correct authorities (for example a member of the mqbrkrs group)?  
Is any operating system limit set too low to allow the command to run?  
Is the environment correctly set up?  
Correct the problem and retry the command, otherwise, contact your IBM support center.
