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(zhuǎn)換IGS后，面的顏色是默認(rèn)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(zhuǎn)或者不轉(zhuǎn)換顏色、圖層。我經(jīng)常是2個軟件合起來用，比較方便。

二、匯編初學(xué)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(xué)了。

用MASM32的調(diào)試程序我感覺還是比較方便的

比如有PrintDec 等函數(shù)（準(zhǔn)確的說應(yīng)該是宏）可以直接在調(diào)試面板中顯示你想知道的寄存器值和指定內(nèi)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(jù)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(dǎo)致該Diskgroup無法mount的問題，后續(xù)DBA采用kfed merge等手法修復(fù)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?yàn)樵搲膲K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(shí)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(dāng)ASM instance crash時可以恢復(fù)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(jù)，后面的數(shù)據(jù)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
