SAPMMC 丢失Instance的找回办法

在使用SCC4复制Client800的时候，磁盘空间不足，导致安装停顿，在我强制关机之后，重启虚拟机下的MMC，结果却丢失了ER1这个服务器。

查找资料时找到了“Layout of SAP Systems Manager Snap-In”其中建议查看Note142100

"Profile parameter mismatch. SAPSYSTEMNAME or SAPSYSTEM doesn't match ...":
The connect to the Web service or DCOM interface was successful, but the used SAP system name or system number used by the SAP MMC snap-in does not match the profile parameters of the connected SAP instance.
Verify the snap-in parameters and the profile parameters of the connected SAP instance.

之后又从Note544533查找到了相应信息，

[2] Question: After stopping the R/3 system, I cannot restart it.What can I do?

Answer:Have you made changes to the profile files?You may have made these changes some time ago but they are only activated when the system is restarted.Proceed as follows:

- Check the following profile files:
Default, start and instance profile,

for incorrect values/entries, for example, incorrect host name, incorrect values for buffer sizes and so on.
- Were the last lines in the files confirmed with 'Return'?
- In addition, check the 'services' file.The last line in this file must also end with 'Return'.

It may be necessary to only retain the most important parameters (see below) in the instance profile and to remove all other values.Try restarting the system with this profile.If the system restarts, you must then analyze which of the parameters/values has caused the problem.

You should also refer to note 129813.

The minimum configuration of the instance profile of a central instance is:

SAPSYSTEMNAME =
INSTANCE_NAME = DVEBMGS
SAPSYSTEM =
SAPGLOBALHOST =

rdisp/wp_no_dia = 2
rdisp/wp_no_vb = 1
rdisp/wp_no_vb2 = 1
rdisp/wp_no_enq = 1
rdisp/wp_no_btc = 1
rdisp/wp_no_spo = 1


在SAP NOTE142100中，找到了思路，根据Note142100的提示，查看usr\sap\ER1\SYS\profile路径下，三个文件的参数是否一致。
1、Default
2、instance
3、start
之后使用备份文件ER1_DVEBMGS01_EXXEPT01.BAK替换了ER1_DVEBMGS01_EXXEPT01。

For some of its functions, the SAP service requires correct profileparameters to which the parameters of the application server shouldcorrespond. Since the service and the dispatcher read differentprofiles, the values may no longer correspond after you change valuesin the instance profile. In this case, you must set the values in thestart profile to the same value or implement the change in the defaultprofile. You can use use "sappfpar pf=" or "sappfparpf=" to compare the parameters. Among others, thisaffects the following parameters:

a) For the dispatcher status: rdisp/myname, rdisp/mshost,rdisp/elem_per_queue, PHYS_MEMSIZE

b) For "Queue Statistic" and "WP Table": rdisp/elem_per_queue,PHYS_MEMSIZE

c) For "Syslog": rslg/local/file, rslg/max_diskspace/local. Inaddition, in Release 6.10, check whether sapservX uses the currentsapevents.dll.

在找回Instance的过程中，关键一步为找到两个合适的sapstartsrv.exe文件，路径分别为：
1、C:\usr\sap\ER1\DVEBMGS01\exe
2、C:\usr\sap\ER1\SYS\exe\uc\NTI386

在运行sapstartsrv.exe的时候，需要勾选“No COM Interface，use only Webservice Interface”，否则会提示“Profile parameter mismatch. SAPSYSTEMNAME or SAPSYSTEM doesn't match ”。
