Hello ,

Oracle 9i (9.0.1.0.0) on HP-UX 11.11
Physical RAM : 2GB

Oracle init.ora parameters :

DB_BLOCK_SIZE=4096
DB_CACHE_SZIE=314572800
LOG_BUFFER 10M
JAVA_POOL 30M
LARGE_POOL 1M
SHARED_POOL 250M With these parameters constant , I set

WORKAREA_SIZE_POLICY=AUTO
PGA_AGGREGATE_TARGET=157286400 (Calculation is (RAM*0.8)*0.2 for OLTP Systems from Oracle Manuals )

Woth these settings I get memory errors ORA-04030

If I set
WORKAREA_SIZE_POLICY=MANUAL & set SORT_AREA_SIZE=10M , obviously I do not Memory errors.

My question ,

What should be reasonable value for PGA_AGGREGATE_TARGET to avoid memory errors ?

Also I would like to know if there is any heavy load if I turn on Multimaster Replication ?

Thanks & Regards,
