Audit Suggestion

Dear Friends,

Our company have been audited by Ernest & Young company.

EY suggested us to perform below things on our Oracle 9.2:

1) Change OUTLN and SYS password.

2) Enabling audit_trail

3) Enabling RESOURCE_LIMIT

I need your confirmation based on EY's audit result if we perform those

changes on our system,

Do we have any impact on our system? What are the impacts?

1) based on OSS notes 562863, we can change SYS and OUTLN password

without affecting R/3 system. However, if i ask my supervisor, he told me

that changing SYS password is not recommended

2) Enabling audit_trail will drop database performance, my supervisor

told me that it is not recommended to enable audit_trail.

3) Enabling RESOURCE_LIMIT, by enabling this password complexity configuration for Oracle will be configured. But, what password will be complex? Is it, for example, OPS$JS1ADM and OPS$ORAJS1 or ora<sid> and <sid>adm?

Need your confirmation on this issue.

Your helps are highly appreciated.

regards,

Ronald
