Do NOT mean to bite the hand that feeds me.
I was a SysAdmin (large IBM and HP UNIX severs). The DBA wanted all the disk, all the I/O threads, and all the CPU. For HIS PIDs.
If the users could not get to HIS DB. HIS DB/SQL environment was NOT the problem!
During root cause analysis HE always made it a point to say:
It was the hardware, network or operating system that were having problems.
I'm now a newbie learning about DB servers and T-SQL, for my investment purposes and having fun doing it.
The DBA had an easy job! Just reading forums with great solutions!!!!
