Hello friends, i am new to openVMS, i want to know that how to run any script automatically at 30 minute time interval. that means i want to run my script only ones and it automatically work at 30 minute interval

irst possibility: get one of CRON or KRONOS packages from the freeware archives. This gives You a Unix "cron"-like interface to schedule tasks. Second possibility: resubmitting batch job: Put this at the beginning of the command-file: $ this = f$environment("PROCEDURE") $ this = this - f$parse(this,,,"VERSION") $ qname = f$getqui("DISPLAY_QUEUE", "QUEUE_NAME","*","THIS_JOB") $ submit 'this'/que='qname'/after=("''f$time()'+00:30") And submit it once to start the sequence.

Hello joseph, thanks for reply But i have got one error in this. i simply first testing this with printing system time at 1 minute interwal as below $ THIS=F$ENVIRONMENT("PROCEDURE") $ THIS=THIS-F$PARSE(THIS,,,"VERSION") $ QNAME=F$GETQUI("DISPLAY_QUEUE","QUEUE_NAME","*","THIS_JOB") $ SHOW SYM QNAME $ SUBMIT 'THIS'/QUE='QNAME'/AFTER=("F$TIME()'+00:01") $ NEXT_NOW=F$CVTIME("","ABSOLUTE") $ SHOW SYMBOL NEXT_NOW but Output which i got is with error of missing qualifier, QNAME = "" %DCL-W-VALREQ, missing qualifier or keyword value - supply all required values NEXT_NOW = "29-JAN-2009 10:10:57.78" Please give me guidance thank you..

You have executed interactively (@test) the file, I have clearly told a resubmitting BATCH job, You have to SUBMIT it. Joseph Huber, http://www.huber-joseph.de

Of course one can write the script in a more general way: first look if we are in interactive or batch mode (see HELP LEXICAL F$MODE), and the decide to first submit, and execute in batch. Since You say to be "new to VMS", before starting programming, I suggest at least to read the VMS user's manual and the DCL dictionary manual (available online from the HP VMS site: http://h71000.www7.hp.com/doc/os83_... Learn the difference between executing a command-file in interactive (@) mode and batch (submit). Joseph Huber, http://www.huber-joseph.de

And one more tip: since in this forum usually only 2 people are answering :-), get used to go into the HP OpenVMS forum at http://forums11.itrc.hp.com/service... You get much quicker answers than here. And You can find most answers to "newbie" questions already in the searchable archive. Joseph Huber, http://www.huber-joseph.de
