User CPU by all Engines Utilization.

Engine cpu sybase. To be successful in this demanding area Sybase focused heavily to optimize and streamline all the layers of our database engine for transaction processing workloads. When running sp_sysmon CPU usage is in the 80- 90 range on a few of the engines while the rest of the engines are showing CPU usage below 20. Sybase ASE Databases Space Statistics.

The utilization varies but at all times the two CPUs are roughly equal. To analyse pressure on CPU you can check how many processes are in running or runnable state. Sybase ASE Performance Statistics.

By default Sybase ASE configures one engine for use. Why when I run mpstat does it show both CPUs being used equally. On occassions during periods of high load one of the engines shuts down and this causes Sybase to freeze.

Sybase Engine CPU Time. If these processes counts are consistently higher than online engine that means there are load on cpu. It is a 2-CPU machine dedicated to ASE.

The number of connections handled by the engine. Using sp_sysmon to determine if high cpu is due to spinlocks. The real problem were having is that they are about 40 others Windows servers running Sybase 125 I believe.

If you have a server machine with multiple CPUs you can enable more engines to take advantage of the machines additional processing ability. Is there any rule such as no of Sybase engines vs Physical CPU. There is one ASE engine running.

Secondss The total time in seconds the engine has been running. We are running ASE 1252 on linux. Thanks--- Posted via the PFCGuide Web Newsreader ---.

Check CPU Busy or User Busy in 157 Threaded Mode. There is high engine thread utilization as per this sysmon output. You need a subscription to comment.

I would like to know if there is any configuration parameter or procedure from which I could know how many CPUs or cores is used by ASE. I would like to have you feedback about the usage of sybase threads engines vs solaris chipcputhreads if there are any settings that must be prevented. As far as I understand the sybase engines are now threaded if configuration parameter kernel mode is set to threaded which is my case meaning that at the system level we see only one process.

We then have to recycle the server to get it up again. Is this normal behavior for Sybase. The ASE server does IO to the raw devices or files these are represented internally as virtual devices.

The number of active locks. Showserver shows just one process. We can expand on the example above with this statement.

Top 10 Engines by User CPU Utilization. For example 99 of cpu crunching might be attributable to the ASEs user time while Sybase and everything else on the machine is totaling up to 22 of system cpu. Sybase Software Asset Management SySAM.

This is ASE 1192 on Solaris 7. Sybase is getting 22 cpu and of that 22 99 is being used by Sybase to process user requests. The DBAs reduced the number of engines to 7 therefor 7 cores are fully used and 1 is kinda free.

The product must process and filter the entire database log at all times even if the majority of the log contains out-of-scope. Theyve got a process copying data from all the 125 sybase servers to the hpux sybase 15. Check Total Cache Hits in the Data Cache Management section.

The Engine section shows how active the server really is regardless of the CPU usage shown on OS level. Sybase ASE Engines Statistics. CPU resources are consumed by different processes on the source and target systems.

Sometimes because of high spinlock ratio also cpu utilization goes high. Is there a limit of Sybase engine CPU. Recently migrated to Sybase 125 and we have 12 Sybase Engines and we have 8 12 GHz Cpus.

CDC Replication Engine for Sybase databases. There are no log entries when this occurs. Capturing decoding and staging the changed data stored in the database log files.

System CPU by all Engines Utilization. Number of CPUs or cores used by Sybase. Top 10 Engines by System CPU Utilization.

Does a single ASE engine get assigned permanently to one physical CPU. The first consideration would be to check for spinlock contention in the sp_sysmon output as shown here in the default data cache subsection under Data Cache Management. I am using Sybase ASE 160 157.

The CPU are running at 90 and Sybase Engines are running at 75. If engines are not showing high busy then spinlocks are not a big issue. Cpu usage MDA mon tables monitor tables engine usage KBA BC-SYB-ASE Sybase ASE Database Platform non Business Suite BC-SYB-ASE-CE.

The Engines tab of the IO Detail view displays information with respect to how each engine. A database can reside on one or spread out on many of these virtual. While this focus turned out to be the asset that catapulted Sybase to a dominant position in highend OLTP.

We are running 3 engines on Sybase. High threadsengine CPU usage and Spinlock contention - SAP ASE.
