Avaya recommends using a specific memory usage configuration for local installations of Oracle. The default configuration that is generated by the installation process causes Oracle to consume too much system memory.
The Avaya-provided /vs/data/init.ora file contains the recommended configuration for running Oracle on the Avaya IR system. Use this file in place of the default init.ora file (usually located in the $ORACLE_HOME/dbs directory) or modify the file using the following values as guidelines:
#db_cache_size=67108864
db_block_buffers=500
hash_area_size=262144
#dispatchers= - disable MTS
#java_pool_size=67108864
#large_pool_size=1048576
shared_pool_size=5000000
