Any assistance would be greatly appreciated.
My first response would be to isolate this application into its own region until the problem is solved. If the problem doesn't occur when this is in a separate region then the question arises as to whether it is a victim. The other thing that hits me is that the Web application may not be fully checking the data it sends and thus corrupting the process. This from a basically batch COBOL programmer who has done some CICS, IMS and DB2 and who was an MVS systems programmer. > >Regards > >Otto Schumacher >Technical Support, CICS > >EDS, an HP Company >Ahold Account >2000 Wade Hampton Blvd. >LC1-302 >Greenville, South Carolina, 29615 > >Tel: 864 987-1417 >Fax: 864 987-4500 >E-mail: otto.schumac...@eds.com > >We deliver on our commitments >so you can deliver on yours. > >---------------------------------------------------------------------- >For IBM-MAIN subscribe / signoff / archive access instructions, >send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO >Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
