SAP ASE 16 installation very very slow on a laptop

[Former Member]

I have two laptops. One is UEFI boot. One is MBR boot. They both have Linux 7.5 installed: CentOS, Oracle Linux 7.5. They are the same as Red Hat Linux 7.5.

Installation of SAP ASE 16 on Dell E6510 MBR boot takes less than one hour.

Installation of SAP ASE 16 on Dell Inspiron 5720 UEFI boot has been running for 20 hours, very slowly go through installation of /app/sap/charsets. I watch it goes from 36 to 44 for one hour. By comparison with MBR laptop, there 88 of them under /app/sap/charsets directory. This will take two one more day to finish.

Why is it running such slow?

Hi David,

ASE is not really certified for derived kernels like CentOS (you may refer to the Certification Report mentioned on SAP Note 1941500 - Certification information for Linux and other Operating Systems - SAP ASE). But anyway strange situation since the OS version is the same on both machines, and no problem in one of them, it seems to be linked more likely to the hardware than the ASE itself. Some suggestion: monitor from OS side resources usage like CPU, memory, disk I/Os ; try with another ASE 16 package level to discard ASE issue (not sure which is the one you are trying to install).

About your last comment: ASE installation logs are located at $SYBASE/log. You may check the installation guide here.

Best regards,

Victoria.

I do not know what the problem was. What I did was to get around the problem.

Originally, I used PuTTY to login, and sent the display of installation back to my Windows' PC. It was hung somehow.

So I tried a different way. I installed TigerVNC server on CentOS 7.5. Then I used to use TigerVNC client connect to it. It worked.

The installation speed of SAP ASE was normal, quickly finished in 20 minutes.

When I used Oracle Linux 7.5 on a different installation, there was no such problem.

So I guess there was some package come with CentOS 7.5 maybe the cause of such problem.

If somebody can help me by point out where to look at the installation log, it would be great.

This Dell Inspiron 5720 is more powerful than Dell E6510. Both of them have 4 cores. After running for more than one day, the installation is stalled at 4%, maybe waiting for something.
