You cannot properly use the IPv4 version of the license server if you have enabled IPv6 on the license server host.
When starting the SySAM license server, this error may be reported:
lmgrd is not running: Cannot connect to license server
system. (-15,570:10035 "WinSock: Operation would
block")
This version of Adaptive Server includes IPv4 and IPv6 versions of the SySAM license server software. Use the
sysam configure command to choose the version of the license server appropriate to your environment. By default, the IPv4 version of the license server is configured for use. You cannot properly use the IPv4 version of the license server if you have enabled IPv6 on the license server host. If this is the case:
- Disable the IPv6 TCP/IP protocol on the license server host.
- Use another Windows host that does not have IPv6 enabled.
- Use a Unix host for the license server. You can use the IPv4 version of the license even if both IPv4 and IPv6 are enabled on Unix
If you are using the IPv6 version of the license server on a Windows host, you can access the license only through the IPv6 protocol. Any host with an IPv4-only network stack cannot obtain licenses from this IPv6 license server. To work around this issue, perform one of the following:
- Use a Unix host for the license server. License servers on Unix can serve licenses to both IPv4 and IPv6 client hosts.
- To use a Windows host for the license server, if you have both IPv4 and IPv6 clients to the license server, set up two license servers: one serving the IPv4 network and the other serving the IPv6 network.
Note: Support for Internet Protocol version 6 (IPv6) is built into the latest
versions of Microsoft Windows, and is available as part of service pack updates
for earlier Windows releases. See Microsoft Internet Protocol Version 6 (IPv6) at
