This set is allocated by the initial connection attempt; each subsequent connection occupying a single license point and returning it when the connection is closed.The initial connection sets the SYSV semaphore to a large value (10000) in order for the driver to be able to use the semaphore as a counter instead of a locking point. The above error is returned by the semctl system call when the kernel value for SEMVMX is lower than 10000.For example, on Sun Solaris, the /etc/system file may include the following entry, which would be too low: set semsys:seminfo_semvmx=4096 Resolution Increase the SEMVMX kernel configuration value to at least 10000. Methods to accomplish this will vary by Unix flavor. Some examples include:1. Solaris: Use the /etc/system file2. HP/UX: Use the "sam" administrative utility3. Linux: Use the "/sbin/sysctl" function. (This allows you to configure kernel parameters at runtime, instead of recompiling and relinking the kernel.)Evidence Creating an ODBC Trace on a Mac Creating a Unix ODBC Trace
