Stopping Information Server (1) KM5021.0 Notes: Before you stop DataStage, you may want to check that no one is using it. There are a number of commands you can use to determine whether DataStage processes are running. The ps –ef command displays process statuses. The grep command searches for a pattern in the output from the grep command. Processes labeled “phantom,” “dsapi,” and “dscs” are DataStage-related processes that indicated either that DataStage jobs are running or that DataStage users are logged into DataStage. The netstat –a | grep dsrpc command displays DataStage network connections. © Copyright IBM Corporation 2007, 2012 Log into the each Engine computer Log in as root, unless IS agents have been configured for non-root administration Check that no one is using DataStage Check if there are any DataStage processes running ps –ef | grep phantom Phantom processes occur when DataStage jobs are running ps –ef | grep dsapi ps –ef | grep dscs Each client connection initiates both a dsapi process and a dscs process Check DSRPC has no established connections If DSRCP is running, it will return a status of LISTEN If connections are established, it will return a status of ESTABLISHED netstat –a | grep dsrpc Each DataStage client connection will show an ESTABLISHED connection Stopping Information Server (1)
