Re: Insufficient heap memory
Dear Avinash, Hope this SAP Note gives you some hints on the"Heap Memory" 1968888 - How to monitor 'heap memory' usage in ASE ? Do let me know if it helps ? RegardsKiran K Adharapuram
View ArticleRe: Insufficient heap memory
Thanks Kiran Before creating this discussion, I had run the queries mentioned in the SAP note to check how heap memory is being used. Of course that was the starting point any way. Per SPID figures...

Could anyone explain in more detail what 478 trace flag does ? Apparently it turns off early placement for a subquery reformatting which seems to be similar to the"store index" optimisation. Does this...

Re: Trace flag 478
HI Mike, I think this traceflag mainly deals with the worktables that are placed in the parsing of the query tree for the subqueries reformatting as per my knowledge Lets see if some one has any other...

View ArticleRe: Bcp tuning
I suspect the decrease in performance is due to the way ASE allocates new extents to objects when doing fast bcp or creating indexes. The allocation process uses the Global Allocation Map (GAM)...
View ArticleRe: Bcp tuning
Hm. That's an interesting note. There are a couple of things that puzzle me in it. If the first extent in each allocation unit it "short" as you labelled it and as such "invisible" to the...

It's shot in the dark, (and you are using process mode, not kernel mode), but a long time ago, when putting ECC on ASE, we found similar 712 errors (see the Best Practices 1.4b doc attached to SAPNote...

HiThis looks like something we are experiencing. But running 9 bcp-in commands and while cpu is almost 100% all the time, I find only two instances of the function calls you mention. See attached...

Chris Thanks for the link. Increasing number of connections is one of the options by which we will get bigger heap memory pool at the reboot of ASE server. And apart from increasing per process memory...
View ArticleRe: Insufficient heap memory
Rather than increasing the number of connections, I would suggest increasing the config 'heap memory per user'. The default is 4K in ASE 16sp02 - I generally recommend 16KB. If performing XQUERY...

Thanks for your feedback. I have done that (i.e. increase heap per process to 32 KB). Will watch this for some time.Increasing number of connections is next possible option if need be. Both lead to...

Hi We see perhaps a small decrease in speed when creating indexes. But not at all the same decrease as bcp-in.Also, if we never create the clustered indexes, speed is fine all the way with all...

sp_dbcc_deletedb can remove the data from these 2 tables for the particular db, can I just do the truncate table on these 2 tables. thanks.
