Our HP support send me information about this Issue that is normally in SAP with HP-UX. The database is Oracle.

I don´t understand that I have more process in Blocked mode that in running mode.

How you see this system? I have one problem or is normally.

The information attached is with verly load in the system

Best reagrds.

maybe because your database is waiting for I/O?

Hi;

How I can check the i/o of my database? The i/o of database is related with the performance of disk?

Best regards
