女生说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图的颜色有些变成白色的呢？望谁能和我说下

proe转换IGS后，面的颜色是默认的颜色，你需要把哪些面改成白色你就先在ASM里改好就成。PROE这方面功能不如UG，UG可以选择转或者不转换颜色、图层。我经常是2个软件合起来用，比较方便。

二、汇编初学者的问题就是怎么查看变量的值知道这个我就可以自己学了。

用MASM32的调试程序我感觉还是比较方便的

比如有PrintDec 等函数（准确的说应该是宏）可以直接在调试面板中显示你想知道的寄存器值和指定内存地址的值

加上

include include\debug.inc

includelib lib\debug.lib

不过这是win32汇编

三、Oracle数据库使用asm存储，asm diskgroup mount不起来，说是报错ora-1

某用户增加LUN到ASM DISKGROUP发现某个ASM Disk header KFBTYP_DISKHEAD被意外清除掉，导致该Diskgroup无法mount的问题，后续DBA采用kfed merge等手法修复了KFBTYP_DISKHEAD block，但仍无法mount diskgroup，ALERT.log中出现如下的日志：

这里可以看到Diskgroup mount到了recovering COD for group 1/0x3a2c35d6 (DG)阶段时，发现了一个逻辑坏块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，并因为该坏块引起了ORA-15196: invalid ASM block header [kfc.c:8281] [endian_kfbh] [2147483648] [2817] [173 != 1]。

这里2817是出错的ASM metadata的block number，173是实际从endian_kfbh位置读出的值，173!=1 这里的1是该位置理论上该有的值，由于读取到block中错误的字节序endian_kfbh信息，所以这里出现了ASM ORA-600错误。

这里recovering COD for group 1/0x3a2c35d6 (DG) 里的COD 指asm metadata file number 4 COD, Continuing Operation Directory (COD) 该metadata file 4 中记录的是在单个metadata block中无法完成的操作记录到COD中，这样当ASM instance crash时可以恢复这些操作。例如创建删除和resize文件，这其中file number 4 blkn=1为KFBTYP_COD_RB 即回滚rollback数据，后面的数据为KFBTYP_COD_DATA。

可回滚的操作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
