Yet you hesitate to be the first on your block to take the XPLunge. Do like Ricky does with Lucy and get some XPLaining first. You may have an XPLeasant alternative. >> CLICK for the full tip: http://www.search390.com/tip/1,289483,sid10_gci800450,00.html If you like this tip, why not drop us an email to let us know.

If you've heard this before, Jim Keohane offers a suggestion: trade off performance vs. maintainability while weighing the cpu improvement as a percentage of the total. Check out his code examples for making performance better than 1/100 cpu second. >> CLICK for the Full Tip... http://search390.techtarget.com/tip/1,289483,sid10_gci765019,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= HOW MANY LPARS PER CPU? | Mark Zelden Dear Ask the Expert: I remember having read (I think in an IBM manual) that the practical limit ratio of LPARS to physical CPUs in a CEC is about two LPARS per CPU. Have you seen this before? >> CLICK to read Mark's response... http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid413925_tax287555,00.html ____________________________________________________________________ :::::::::: DON'T MISS THESE IMPORTANT MESSAGES AND LINKS ::::::::: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= DISCUSSION FORUMS | Developer Search390 member ndbaguley posted the following in the Developer forum and needs your help: I am trying to find out how to test for member level (in this case COBOL) initiation in an LE enclave. I need to do this in order to use IGZCXCC. The enclave is actually a child enclave created by the issuing of a link SVC. The LE child enclave is created by an assembler conforming LE module. At a later stage I issue a call to IGZCXCC which expects LE and COBOL to be active. COBOL is active in the parent enclave but not the child enclave. I get an RC=4 and IGZ0099 msg. Can I check entry 5 of the member entries chained of the CAA for a dummy event handler? Any help much appreciated! Think you can answer ndbaguley's question?
