Few days back we had an issue where DASD went up to 97% and even higher... Due to a user who have created a large file: Library . . . . . . : ABC Object Type Attribute Text XYZ *FILE ********** "Object with size has grown extremely High" We took a service dump and the system IPLed. Could nay one tell me a process or a program to keep an eye(generate a report) on fast growing objects or atleast objects that are of large size ?

Thanks. We'll let you know when a new response is added.

There are various ways; Some proactive and some reactive.

ProActive, you can limit the size of objects owned by a user bu using the MAXSTG parm on the USRPRF.

You can limit the size of PFs by not using SIZE(*NOMAX)

ReActive, you can run RTVDSKINF and PRTDSKINF to find the size of large objects on your system.

    Library . . . . . . : ABC Object Type Attribute TextXYZ *FILE ********** “Object with size has grown extremely High”   What is that? It appears to be copy/pasted from somewhere, but from what?   Tom

    So is there any call program which we can have to generate a report of objects with big size? The RTVDSKINF retrieves information about objects in libraries, and PRTDSKINF prints reports about those objects. There are also RTVDIRINF and PRTDIRINF for information about directories. Usually they don't help much unless you run the commands regularly so you can compare sizes against previous values.   But again, where did the data in your question come from? It might help in finding an appropriate answer.   Tom
