>From DB2 Admin Guide: "DB2 can recall user page sets that have been migrated. Whether DFSMShsm recall occurs automatically is determined by the values of the RECALL DATABASE and RECALL DELAY fields of installation panel DSNTIPO. If the value of the RECALL DATABASE field is NO, automatic recall is not performed and the page set is considered an unavailable resource. It must be recalled explicitly before it can be used by DB2. If the value of the RECALL DATABASE field is YES, DFSMShsm is invoked to recall the page sets automatically. The program waits for the recall for the amount of time that is specified by the RECALL DELAY parameter. If the recall is not completed within that time, the program receives an error message indicating that the page set is unavailable but that recall was initiated." http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2z9.doc.admin%2Fsrc%2Ftpc%2Fdb2z_dfsmshsmeffectonrecovery.htm http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2z9.doc.inst%2Fsrc%2Ftpc%2Fdb2z_dsntipo.htm http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2z9.doc.admin%2Fsrc%2Ftpc%2Fdb2z_migratetohsm.htm Norbert Friemel ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
