Set user and group privileges on the Permissions tab. Enable or disable server-side tracing on the Tracing tab. Specify a user name and password for scheduling jobs on the Schedule tab. Specify parallel job defaults on the Parallel tab. Specify Job Sequencer defaults on the Sequence tab. 1.1. What are the ways to execute datastage jobs? A * * * * job can be run using a few different methods: from Datastage Director (menu Job -> Run now...) from command line using a dsjob command Datastage routine can run a job (DsRunJob command) by a job sequencer
1.2. How to invoke a Datastage shell command? Datastage shell commands can be invoked from : * Datastage administrator (projects tab -> Command) * Telnet client connected to the datastage server 1.3. How to stop a job when its status is running? To stop a running job go to DataStage Director and click the stop button (or Job -> Stop from menu). If it doesn't help go to Job -> Cleanup Resources, select a process with holds a lock and click Logout If it still doesn't help go to the datastage shell and invoke the following comm and: ds.tools.It will open an administration panel. Go to 4.Administer processes /locks , then try invoking one of the clear locks commands (options 7-10). 1.4. How to run and schedule a job from command line? To run a job from command line use a dsjob command Command Syntax: dsjob [-file | [-server ][-user ][-password ]] [] The command can be placed in a batch file and run in a system scheduler. 1.5.

The role privileges are: * DataStage Developer - user with full access to all areas of a DataStage projec
t * DataStage Operator - has privileges to run and manage deployed DataStage jobs * -none- - no permission to log on to DataStage 1.8. Is it possible to run two versions of datastage on the same pc? Yes, even though different versions of Datastage use different system dll librar ies. To dynamically switch between Datastage versions install and run DataStage Multi -Client Manager. That application can unregister and register system libraries u sed by Datastage. 2.18. Use and examples of ICONV and OCONV functions? ICONV and OCONV functions are quite often used to handle data in Datastage. ICONV converts a string to an internal storage format and OCONV converts an expr ession to an output format. Syntax: Iconv (string, conversion code) Oconv(expression, conversion ) Some useful iconv and oconv examples: Iconv("10/14/06", "D2/") = 14167 Oconv(14167, "D-E") = "14-10-2006"
