Upgrade CPU and RAM

Upgrade CPU and RAM

 

  

Dear All,

The current hardware configuration of our DB2 Database
Server contains 2 CPU's and 3GB RAM. Now we planning to upgrade to 3
CPU's and 5GB RAM.

Could you please inform what necessary configuration changes should be
done on DB2 database configuration to take up this hardware changes?



Some of the DBM configurations are:



Database monitor heap size (4KB) (MON_HEAP_SZ) = 560

UDF shared memory set size (4KB) (UDF_MEM_SZ) = 256

Java Virtual Machine heap size (4KB) (JAVA_HEAP_SZ) = 2048

Audit buffer size (4KB) (AUDIT_BUF_SZ) = 0

Backup buffer default size (4KB) (BACKBUFSZ) = 1024

Restore buffer default size (4KB) (RESTBUFSZ) = 1024

Sort heap threshold (4KB) (SHEAPTHRES) = 20000



Some of the DB Configuration:



Database heap (4KB) (DBHEAP) = 2048

Catalog cache size (4KB) (CATALOGCACHE_SZ) = 64

Log buffer size (4KB) (LOGBUFSZ) = 512

Utilities heap size (4KB) (UTIL_HEAP_SZ) = 5000

Buffer pool size (pages) (BUFFPAGE) = 4000

Max storage for lock list (4KB) (LOCKLIST) = 100

Lock timeout (sec) (LOCKTIMEOUT) = 15

Sort list heap (4KB) (SORTHEAP) = 512

SQL statement heap (4KB) (STMTHEAP) = 2048

Default application heap (4KB) (APPLHEAPSZ) = 1024

Log file size (4KB) (LOGFILSIZ) = 8192

Number of primary log files (LOGPRIMARY) = 6

Number of secondary log files (LOGSECOND) = 3
