女生說asm是什么意思啊

一、PROE里面怎么把ASM格式改成IGS格式。里面3D圖的顏色有些變成白色的呢？望誰能和我說下

proe轉換IGS后，面的顏色是默認的顏色，你需要把哪些面改成白色你就先在ASM里改好就成。PROE這方面功能不如UG，UG可以選擇轉或者不轉換顏色、圖層。我經常是2個軟件合起來用，比較方便。

二、匯編初學者的問題就是怎么查看變量的值知道這個我就可以自己學了。

用MASM32的調試程序我感覺還是比較方便的

比如有PrintDec 等函數(shù)（準確的說應該是宏）可以直接在調試面板中顯示你想知道的寄存器值和指定內存地址的值

加上

include include\debug.inc

includelib lib\debug.lib

不過這是win32匯編

三、Oracle數(shù)據庫使用asm存儲，asm diskgroup mount不起來，說是報錯ora-1

某用戶增加LUN到ASM DISKGROUP發(fā)現(xiàn)某個ASM Disk header KFBTYP_DISKHEAD被意外清除掉，導致該Diskgroup無法mount的問題，后續(xù)DBA采用kfed merge等手法修復了KFBTYP_DISKHEAD block，但仍無法mount diskgroup，ALERT.log中出現(xiàn)如下的日志：

這里可以看到Diskgroup mount到了recovering COD for group 1/0x3a2c35d6 (DG)階段時，發(fā)現(xiàn)了一個邏輯壞塊WARNING: cache read a corrupted block gn=1 dsk=0 blk=2817 from disk 0 NOTE: a corrupted block was dumped to the trace file ERROR: cache failed to read dsk=0 blk=2817 from disk(s): 0，并因為該壞塊引起了ORA-15196: invalid ASM block header [kfc.c:8281] [endian_kfbh] [2147483648] [2817] [173 != 1]。

這里2817是出錯的ASM metadata的block number，173是實際從endian_kfbh位置讀出的值，173!=1 這里的1是該位置理論上該有的值，由于讀取到block中錯誤的字節(jié)序endian_kfbh信息，所以這里出現(xiàn)了ASM ORA-600錯誤。

這里recovering COD for group 1/0x3a2c35d6 (DG) 里的COD 指asm metadata file number 4 COD, Continuing Operation Directory (COD) 該metadata file 4 中記錄的是在單個metadata block中無法完成的操作記錄到COD中，這樣當ASM instance crash時可以恢復這些操作。例如創(chuàng)建刪除和resize文件，這其中file number 4 blkn=1為KFBTYP_COD_RB 即回滾rollback數(shù)據，后面的數(shù)據為KFBTYP_COD_DATA。

可回滾的操作opcodes包括：

1 - Create a file

2 - Delete a file

3 - Resize a file

4 - Drop alias entry

5 - Rename alias entry

6 - Rebalance space COD

7 - Drop disks force

8 - Attribute drop

9 - Disk Resync

10 - Disk Repair Time

11 - Volume create
