Error description
New Function - Allow CHECK with SHRLEVEL CHANGE to use FASTREPLICATION(REQUIRED) when invoking dssCopy
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 9 for z/OS and * * DB2 10 for z/OS users of * * CHECK utilities * **************************************************************** * PROBLEM DESCRIPTION: Add a zparm to control * * FASTREPLICATION keyword on DSSCOPY * * command of CHECK utilities. * **************************************************************** * RECOMMENDATION: * **************************************************************** CHECK utilities using SHRLEVEL CHANGE invoke DSSCOPY to copy shadow data sets on which the CHECK is performed. The copy command uses the FASTREPLICATION keyword. The options FASTREPLICATION(REQUIRED) and FASTREPLICATION(PREFERRED) are allowed. This APAR adds a new DB2 subsystem parameter called CHECK_FASTREPLICATION in DSN6SPRM for specifying the FASTREPLICATION setting for the CHECK utility. CHECK_FASTREPLICATION can be set to either PREFERRED or REQUIRED: * If you specify REQUIRED, the CHECK utilities force DSSCOPY to use fast replication, ensuring that object copies occur as quickly as possible, thus reducing the opportunity for resource contention and unavailability. This option will cause CHECK to fail if Flash Copy cannot be used. ==> This is the default setting in DB2 V10. * If you specify PREFERRED, the CHECK utilities direct DSSCOPY to use fast replication only if Flash Copy support is available. ==> This is the default setting in DB2 V9.
Problem conclusion
Temporary fix
Comments
Add zparm to control FASTREPLICATION keyword for CHECK utilities with SHRELEVEL CHANGE. Please note that although this is a V9/V10 APAR, it does include a small V8 change. The APAR updates DSNADMIZ, the external module for the SYSPROC.ADMIN_INFO_SYSPARM stored procedure in DB2 V8, V9, and V10 so that it can report the setting for the new CHECK_FASTREPLICATION subsystem parameter. In DB2 data sharing, a SYSPROC.ADMIN_INFO_SYSPARM connection on any member of the group can query the subsystem, DECP and certain IRLM parameter settings of any other member of that group. In order to support V9 and V10 data sharing coexistence modes, the V8 SYSPROC.ADMIN_INFO_SYSPARM must recognize the new CHECK_FASTREPLICATION subsystem parameter.
