Dear specalist and customers, I need some help for the TDP 2.2 Product of our Exchange Servers. We backed up our Information-Stores over a GB/Ethernet tcp/ip connection with very bad performance and long durations. After some tunings we got an "unknown API-Error" Code 425.
But first some Hardwareinformations: We use Compaq-Server with four 450 MHz prozzessors, 4 GB Ram, GB/Eth.-card, Exhange 5.5 incl. SP4, Win NT 4.0 incl. SP 6a, TSM B/A Client 4.2.1.16, TDP 2.2 and in the Backend a Comparex Tetragon Disk-Subsystem. To tune the performance we opened a problemrecord with IBM and changed some parameters (Buffersize from 1024 to 8192 and Buffers from 3 to 8). After this tunings we got the first time the "code 425" and we doesn 't got out of this Problem yet by the way of uesing GB/Ethernet. Does anyone have also bad Experiance with this Error ? IBM told us, that this problem is based on the Microsoft API-Interface. There should be an HRBACKUPREAD-Problem with filling up the Buffers with Datas as fast as it should be done. The time is probably too long and than it becomes a timeout followed by the unknown API-Error. Is there someone who can help us? May a lot of TDP users have the same, unexplained problem. It would be nice to here of you soon. kindley regards Wolf-Christian Lücke K-DOI-44 Volkswagen AG Wolfsburg Storage Management Windows Platform Tel.: 05361/9-22124 E-Fax: 05361/9-57-22124 E-Mail: mailto:[EMAIL PROTECTED]
