Hi everybody.
Relatively new with SAP so please bear with me :-)
SAP ECC 6.0.0 Enhancement Package 5 running on RedHat Linux ES 6.0 64bit.
A colleague of mine created a very long list spool request; there are approx 17.000 pages with 346MB reported in the TemSE attributes.
If I try to SP01 - > Spool Request -> Forward -> Export as Text, the procedure completes in more than 20 minutes and it produces an approx 130MB text file.
Backend systems are located in out corporate network which the SAP GUI accesses via Gigabit Ethernet connection.
I've tried with both the SAP GUI Java for Mac and the native one for Windows but times are the same.
As soon as I select the "Export as Text" option, the file starts to get written locally at approx 1MB every 10 seconds; again, network performances between the GUI and the application server are good (100MB/sec) and the same goes for the AS -> DB Server (which is Oracle 11.1).
From SM51 I see the work process devoted to this operation; I see several direct read from table TST03 (TemSE data) but it seems to me there are a number of separately "runs" (namely, SAPLSPRR and SAPLSPOOL_SP01R) as to extract small chunks of data every time (approx every 10 seconds).
If I browse table TST03, I see approx 44.000 entries with TemSe Object Name = <name of the spool request> so I suspect the whole jobs is being splitted into much smaller elements (approx 10.000 bytes each) which have to be retrieved one by one from the database and then assembled before getting to the presentation layer.
According to "top" executed on the application server, the CPU assigned to the "spool" work process is approx 70/80% busy CPU mode (the app server is a physical one with 2x8 core Intel(R) Xeon(R) CPU E5-2680 at 2.7Ghz.
From the DB server side, the system is quite idle (approx 92%) with little I/O (approx 7/8%).
Given the amount of pages to be retrieved from the DB, are 20+ minutes kind of expected?
Where I can start investigating from as to find out if there are issue with the application servers/DB?
Thanks,
Rob
