cttctx cttctx is a multi-threaded c-tree client test for comprehensive testing of c-tree server operations. This utility was designed specifically for profiling c-tree performance. Use this utility to simulate high load conditions against the c-tree server for verifying application performance. Usage cttctx <uid> <upw> <svn> [create [-t<trnmod>] | <nThrds> [-c<concurrency>] [-d<dist>] [-e] [-h] [-j] [-o<op>] [-p] [-r<msec>] [-n<niter>] ] Arguments • <uid> User name • <upw> User password • <svn> c-tree Server name • create Create new test data/index files • -t<trnmod> Transaction mode to use when creating the files • trnmod is one of the following o t ctTRNLOG o p ctPREIMG o n no tran • <nThrds> Number of c-tree threads to spawn • -c<concurrency> Change thread concurrency to <concurrency> • -e Use the embedded c-treeSQL interface (otherwise use the ISAM interface) • -h Hard exit, abrupt termination without thread cleanup • -j Add to vlength files • -o<op> Operation to apply • <op> is one of the following: o a Add o r Read o d Delete • -p track performance stats such as latency of operations • -r<msec> Number of milliseconds between performi Refer to c-tree Server Administrator's Guide for additional information on this utility.
