4326.0. "DAP error: Linear buffer size integrity check failed" by HLRG02::SYSTEM (Opel Manta GSI) Mon Jan 04 1993 11:57

Hi,


		FIRST I WISH ALL THE MCC-FOLKS A HAPPY 1993.



I wanted to install the AIRCO DEMO AM but while 'Building containment tree file'
I got the following error message:
	Linear buffer size integrity check failed

I have already installed the AIRCO DEMO AM on another system (microvax 3600) and 
there I had no problems at all.


My system is:
VS 4000 - 60
40 MB
DECmcc T1.3.0


Are there known problems with the DAP, is there a work around, do I have to 
place a QAR.

Any suggestion is appreciated.


Kindest regards,


/-/	Henk.

	Hi Jerry, > o Is this problem reproducible? I think not, because installing the AIRCO DEMO AM on the microvax was succesfull. But installing this on the VS4000-60 is got the error, when I did after this a man/tool the AIRCO entitie was there?? I did a man/tool delete class AIRCO and after that I did again a install. Now the install was succesfull. So I have no really a problem, but maybe I encountered a bug somewhere. > o Also, please send me all DAP command files that the AIRCO DEMO > loads into the dictionary. The dap command files you can find at: HLRG02::MCC_AIRCO_AM_MGMT_IF.COM HLRG02::MCC_AIRCO_AM_SRVC_IF.COM Thanks for your reply. /-/ Henk.

	Henk: This was a tough problem to solve. I ended up finding and fixing two problems: o First, I was able to reproduce the symptom you described on any dictionary (big or small), by executing two REBUILD commands in succession. This problem was easy to fix (initialization problem) and the fix has been put into the V1.3 FT Update kit (class t1.3.1). o However, I was not convinced that this was the same reason why you experienced the problem with the AIRCO DEMO installation. So, I tried to reproduce the problem on many different dictionaries of many different sizes. I was unsuccessful and was beginning to give up when a co-worker gave me a 67MB ULTRIX dictionary (70 MIBS loaded) that exhibited this same problem! This dictionary turned out to be corrupt. A couple of records had child pointers for records that weren't in the dictionary. This caused some data loss in the CTM build algorithm that caused the error message that you saw. I have changed the CTM build algorithm to ignore these corrupt records and to continue to build the CTM file. These changes are also included in the V1.3 FT Update kit (class t1.3.1). I am not sure why your dictionary got corrupted. One way that this can happen is if a LOAD, UPDATE, DELETE, AUGMENT or MERGE operation was interrupted during processing. In fact, the building of the 67MB dictionary I used was indeed interrupted during a MERGE operation. Unfortunately there is no easy way to confirm the integrity of your dictionary. However, the fixes that I've made in the FT Update kit should alleviate the effects of any small corruption in your dictionary. That's all I can do for now... - Jerry
