Hi TSM-ers!
Today and last weekend we encounted a filled recovery log on two different 
servers. It looks like both of them were caused by a pinned recoverylog. TSM 
started one incremental after the other, but could not free up space. I had to 
bounce both servers.
I found two parameters to prevent the log from getting pinned 
(THROUGHPUTDATATHRESHOLD and THROUGHPUTTIMETHRESHOLD) but I found no 
recommended values...
Another document talks about limiting the size of files written to the 
diskpool. Large files written to a fragmented diskpool tend to pin the log too. 
I know my SQL clients are the only clients writing very large backup files. I 
cannot find a DP for SQL Server parameter to tune this. I know you can set the 
file size in the DP for Oracle and SAP client. Is this also somehow possible in 
the SQL Server client?
Thanks in advance for any reply!
Kind regards,
Eric van Loon
