Good Morning,

I’d appreciate any input/suggestion that you have.

We have license for Sybase IQ of 32 cores. On the hardware side we have Oracle T5-4 server running on SPARC Solaris 10 O/S with 1TB memory, 8 physical CPUs, each CPU has 256 virtual cores.

If we install the Sybase IQ on this hardware, beside it seems that we will waste a large portion of the available resource, is there any “cons” that we don’t know?

If it’s Okay to install Sybase IQ 16 on this H/W what can we do to take advantage of the extra resource for the performance?

I guess we can run ASE on the same physical T5-4 without affecting the performance of the IQ server, is that correct?

Does SAP support Sybase IQ in Solaris containers/zones?

Thank You all in advance,

HongVarley

If IQ smells more than 32 cores on that host in whichever mode you run. IQ won't start!!

Hello,
can you not just limit it to 32 cores by using -iqnumbercpus on start up.

Cas

Thank You Carlos and CAS !

We have the parm -iqnumbercpus 32 in our current server CFG file on a Unix host of 256 virtual cores (which is existed in long before my time )

Carlos, in our case, the license is for 32 cores, "the IQ won't start if it smells more than 32 cores on the host" , is that because the IQ's -iqnumbercpus links with the license's number of cores? if this is the case, it explains presence of the -iqnumbercpus 32 in our CFG file

Thanks to you both.

Regards,

-Lan V.

You are licensed by what cpuinfo core value is stated ( under Sysam / bin ) regardless of your startup params -iqnumbercpus !
