Error description
Optimize memory usage in Merge and Object Compare
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of Db2 Administration Tool for z/OS * * who use Db2 Object Comparison Tool to * * compare large numbers of objects * **************************************************************** * PROBLEM DESCRIPTION: When a large number of objects are * * compared with Object Compare, * * ONCODE condition 451 might occur. * **************************************************************** When comparing a large number of objects, especially tables, table spaces, and views, modules ADBCCMM and ADB2CM* allocate a lot of memory to process those objects. Additionally, when a summary report is requested, it needs a lot of resources to display the large number of objects. This behavior might cause any of the following ONCODE 451 conditions: IBM0451S ONCODE=451 The STORAGE condition was raised. From entry point ADBCCMM at statement >statement< at compile unit offset >offset< at entry offset >offset< at address >address<. IBM0451S ONCODE=451 The STORAGE condition was raised. From entry point PRINT_SUMMARY_REPORT at statement >statement< at compile unit offset >offset< at entry offset >offset< at address >address<. Keywords: ONCODE451
Problem conclusion
This APAR reduces the possibility of receiving ONCODE 451. The storage allocation is optimized, and the internal program object limit is increased. Receiving ONCODE condition 451 is still possible depending on the objects being compared and the system environment.
