Re: Value for CIPC regular message pool size
The intent of 'well-partitioned' is to minimize writing by more than one node to the log device (i.e. keep writes to one instance). You are still going to get shadow locks and cache page movement as...

You could have tried using the select lct_admin("abort",spid) command to kill the culprit spid. rather than booting the ASE server.Hope you this helps. Regards, Swapnil

Hi Dilip, Looks like your Sybase ASE sysconfigures table's data has been corrupted . That is the reason it is giving configuration number "652" value is invalid in error messages. use dbcc commands to...

I could and I will try next time but experience tells me you can't kill a process using lct_admin while it is not in log-suspend state. Besides, I'm using "abort tran on log full" so the process would...

If the SPID is not in log suspend mode lct_admin will NOT help. On test server open a session and try using lct_admin("abort", spid) and it will return error saying said spid in the database is not...

I'd start with running sybdiag + collecting all possible metrics on the SPID (all MDAs that have any reference to SPID), collect multiple stacktraces (dbcc stacktrace(spid)) and send all this stuff to...

View ArticleRe: ASE on Power8 / 16 Cpus + SMT8 ( 128 Vcpus)
The problem is that the engines are largely idle - check monThreads - especially with idle timeout set that high. I'd reduce idle timeout to 250 for a start. When the engines are idle (no task in...

Thanks Jeff I my case the threads User time reaches 60%/70% , so the engines are not excaclty idle. My main question how Can I evaluate the rate or % of the spinlock activity on overall Engine % Usage...
View ArticleRe: ASE on Power8 / 16 Cpus + SMT8 ( 128 Vcpus)
30-40% Idle is still quite a bit (with large engine counts and aggressive task stealing enabled) and is precisely what I was saying. But you really need to look at IdleTicks:BusyTicks and TotalTicks.

You've mentioned a 'new server' so I'm guessing your migration consisted of dumping from 12.5.4 and loading into 16.0 (ie, you did *not* do an in-place upgrade of the dataserver). In the case of...
