Your standalone enqueue is configured with two I/O threads (parameter "enque/server/threadcount = 2"). THIO: I/O thread n (no specified: all I/O threads)ģ: Set/get trace status information on/from the enque serverĤ: Reload Enqueue Server ACL file (simple request)ħ: Get information about all enqueue server threadsĮxample: increasing the trace level of the I/O thread 1 only
