SQLBase 7.5.1 - Dual Processor

SQLBase 7.5.1 - Dual Processor

SQLBase 7.5.1 - Dual Processor


  We are currently running Visual Manufacturing 6.13 on SQLBase 7.5.1, every once in a while we have to re-boot our server as someone is running reports on the database that spikes the CPU.

Q1:  Would dual processors help this?
Q2:  Does SQLbase 7.5.1 support dual CPU?  Does Visual need to?
Q3:  Does the server need to be shut down at all when this type of problem comes up?  Or can SQLbase just be restarted.

Thanks in advance!

RE: SQLBase 7.5.1 - Dual Processor

Q1 : No
Q2 : No
Q3 : (a) Just restart SQLBase
     (b) While waiting, fix query - high CPU isn't necessarily bad, but with a long execution time generally is.  The implied lack of IO combined with long execution time might suggest a poor query design.

RE: SQLBase 7.5.1 - Dual Processor

SQLBase will clearly run on a multi-processor system (as evidenced by our quad 2.8 GHz machine with 4GB of RAM) but that doesn't necessarily mean that it's taking advantage of the full system resources.

SQLBase is a very low-end RDBMS and I am attempting to leverage its limitations to sell my GM on an upgrade to Oracle (which we're probably going to do anyway when/if we implement Lilly's DCMS). I really hate the lack of support for several features I consider invaluable:

-outer joins to multiple tables (which aren't an option until SQLBase 8.5)
-sub-SELECT statements in the FROM clause
-multiple attribute sub-SELECT statements (e.g. if I want the sub to look for specific combinations of more than one field: WHERE (attribute1, attribute2) IN (SELECT...) )

If anyone is aware of a work-around for any of these limitations, please let me know.
