11g background processes

My 11g instance shows the following processes:

ora_pmon_eleveng
ora_vktm_eleveng
ora_diag_eleveng
ora_dbrm_eleveng
ora_psp0_eleveng
ora_dia0_eleveng
ora_mman_eleveng
ora_dbw0_eleveng
ora_lgwr_eleveng
ora_ckpt_eleveng
ora_smon_eleveng
ora_reco_eleveng
ora_mmon_eleveng
ora_mmnl_eleveng
ora_d000_eleveng
ora_s000_eleveng
ora_smco_eleveng
ora_fbda_eleveng
ora_qmnc_eleveng
ora_q000_eleveng
ora_q001_eleveng
ora_cjq0_eleveng
ora_w000_eleveng
ora_j000_eleveng

I compared the 11g processes above with a 10g instance and found that 6 new background processes had been introduced in 11g which are:

ora_dbrm_eleveng DB resource manager
ora_dia0_eleveng Diagnosability process 0
ora_fbda_eleveng Flashback data archiver process
ora_vktm_eleveng Virtual Timekeeper
ora_w000_eleveng Space Management Co-ordination process
ora_smc0_eleveng Space Manager process

However while googling the net, I found that 56 new processes were added. I am pasting those here for reference, just in case the original link disappears:

In Oracle 10.2 there were 157 background parameters; in Oracle 11.1 there are 212 background processes

The following table shows the 56 background processess that were added in Oracle 11.1

Hi Arun,

Great to hear from you. I was wondering how to get in touch with you since my laptop got formatted by IT helpdesk guys (which is their standard solution for every problem). I had lost your personal email id because of the resulting data loss.

Your blog is very impressive. I just went through it. Apps Health Check post was very good. Will keep checking it. I am adding your blog to my site's blogroll.

Do keep in touch.
