zpool more than 80% but ZFS SAN storage is still lower than 80% will it affect performance?

984266Jun 13 2013 — edited Jun 14 2013

HI All,

As we know, in ZFS, it is recommended to keep the disk usage below 80% to ensure the performance.

However, the following is my scenario:

I have a ZFS storage, which share by multiple servers, and overall Usage is lower than 80%.

Server A has multiple  Lun (spool) from this storage, For example:

- LUNPOOL/A

- LUNPOOL/B

- LUNPOOL/C

Currently, LUNPOOL/B of server A is more than 80%, it reach 88%.

Since the overall storage there still lower than 80 %,  will the performance for this LUNPOOL/B be affected?

It is possible the breakpoints aren't on code lines - sometimes the apparent line numbers are wrong. Try bracketting a line with breakpoints on either side.

Following your suggestion, I put break point on 6 lines following the DBMS_DEBUG_JDWP.CONNECT_TCP call.
3 of those lines are code lines. I also have 2 break points on code lines in a procedure being called at one of those 6 lines.

I have no problem hitting those stops if I 'Run as Debug'... but they are ignored when doing the remote debug.
In the remote debug session I do see all the break points lists in the Breakpoints tab. I'm very confused.....
An experiment -

Tools > Preferences > Debugger

Start Debugging Option:
- Step Over


Try this. This allows you to start a debug session sans breakpoints. You can then step over or into your code once the debugger session 'attaches.' I believe this will work for remote...

Good suggestion, but I already had that debugger property set.

I got it working! What I didn't realize was that you need to be logged into the database with the same credentials in both the local and remote session. I was trying to debug as the package owner and executing the procedure using our 'web' runtime user id.......

I learned that the break points are userid specific.

Thanks for all your great suggestions!
