New Background Process in 11G


This articles will describe the new background processes that has been introduced in oracle 11GR1.The background process in oracle 11.1g  are

ora_pmon_11G
ora_vktm_11G
ora_diag_11G
ora_dbrm_11G
ora_psp0_11G
ora_dia0_11G
ora_mman_11G
ora_dbw0_11G
ora_lgwr_11G
ora_ckpt_11G
ora_smon_11G
ora_reco_11G
ora_mmon_11G
ora_mmnl_11G
ora_d000_11G
ora_s000_11G
ora_smco_11G
ora_fbda_11G
ora_qmnc_11G
ora_q000_11G
ora_q001_11G
ora_cjq0_11G
ora_w000_11G
ora_j000_11G

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_11G         DB resource manager
ora_dia0_11G          Diagnosability process 0
ora_fbda_11G          Flashback data archiver process
ora_vktm_11G         Virtual Timekeeper
ora_w000_11G        Space Management Co-ordination process
ora_smc0_11G         Space Manager process

However while googling the net, I found that (212-157+1=) 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
