Are lack of memory and disk space the culprits for a logon error?

Learn how to determine if lack of memory and disk space the culprits for a logon error in this expert Q and A with Basis expert Giovanni Davila.

We have SAP 6.20 installed in one of our systems. The system configuration is as follows: Intel Pentium III, 850 Mhz, 128 MB RAM, 40 GB hard disk. We are able to connect to the SAP server maintained by HCL. When we try to log in using SAP logon, the login screen appears. But when we try to log in, it displays a SAPGUI 620 sapdp00-error.
Analyze the developer traces (dev_*) files under "usrsap<SID>DVEBMGS00work.

The lack of memory in your system might be the culprit of the problem. Anything based on Web AS 6.20 needs much more than 128MB of RAM. Even 512MB of RAM is the bare bone minimum for a one-user test system. Also, you should consider adding more disk space and more than one disk. Performance with a single disk is terrible.
