ECC 5.0 Two Errors .....

Hi,

I have installed system ECC 5.0 as sandbox.

With Win 2003 Oracle 9.2.0.6 with 2 GB RAM. HDD 320GB 160+160 Two HDD's (one partiion on each HDD of 160GB)

First Question :

When i am trying to execute DB02 its giving me a pop up called "will take some time to collect from db monitors " when i said yes.

The process is ending with TIME_OUT Error ? How to overcome this.

I suppose 600sec is not enough for collecting stats.

I tried to increase max runtime for dia process to 1000 but after restarting msg sever is not starting...

Question Two :

When i am tring to change any parameter in rz10. like changing no of wp, changing size of PHY_MEM etc.

After restarting the server for changes to apply i am not getting any instance in MMC console. so that i can't start my sap.

After i overwrite profiles from backup. then its working fine?

What may be the cause ?

Thanks in Advance.
