关于RACchec工具的问题
大家好,今天试着用RACcheck这个工具来检查Orcle 11.2.0.3 RAC环境,准备升级。但RACcheck这个工具发生了几个错误。
我用的版本是RACCHECK VERSION: 2.2.3_20131007
错误1:
OS参数net.core.rmem_default检查时发生误报。
本来已经设置好的参数无法检查到。
经常MOS,找到一篇相似的文档
RACcheck Known Issues (Doc ID 1509746.1)
RACcheck2.2.0以降のバージョンで、Linux環境で誤って不正情報を報告します。
7. RACcheck 2.2.0 Upgrade Readiness (pre) falsely reports incorrect semaphore
settings on Linux
Problem Symptoms:
PASS => Kernel parameter SEMMNI OK
Check:- FAIL => Kernel parameter SEMMNS is lower than the recommended value
Check:- FAIL => Kernel parameter SEMMSL is lower than the recommended value
Check:- FAIL => Kernel parameter SEMOPM is lower than the recommended value
Solution: Manually validate the proper semaphore settings as shown below and
ignore
the error. This issue is the result of internal Bug# 16104290 which only appers in
the Upgrade Readiness (pre check) feature. This bug is fixed in versions above
2.2.0 and does not exist in versions below 2.2.0.
错误2:
RAC环境中,一个节点的已经安装的RPM包可以正常检查到,
但另一个节点已经安装的RPM包无法正常检查到。发生下面的错误:
节点1
PASS => Package libaio-devel-0.3.106-3.2-x86_64 meets or exceeds recommendation
节点2
FAIL => Package libaio-devel-0.3.106-3.2-x86_64 is recommended but NOT installed
在MOS上找到下面的文档,有相似的地方
Bug 14612478 : RACCHECK SAYS PACKAGE GPFS.BASE-PPC_64 IS MISSING ON 1 NODE,BUT ARE NOT ON BOTH
错误3:
其实这个也不算是错误,应该说是一种现象。
在RACcheck所出的报告最后有一个自动跳过的检查。
这个跳过的的原理是什么?我在MOS上并没有找到。
请高手指点一下。为什么就不检查这些项目。在不同的机器做过检查,每个RAC环境跳过的东西还不一样。
例:
环境1:
Skipped Checks
skipping ACFS and ASM driver version comparison (checkid:-83BAB365727F7DD6E040E50A1EC043AD) because o_acfsutil_log_rac1.out not found

skipping GI shell limits soft nofile(checkid:-841D87785594F263E040E50A1EC020D6) because o_crs_user_limits_rac1.out not found
环境2:(RAC+DG环境))
skipping Standby Database Info(checkid:<略>) because audit check execution failed with exit code 2. https://support.oracle.com/epmos/faces/SearchDocDisplay?_adf.ctrl-state=pg80cnb2z_9&_afrLoop=5188867294108
这里有一篇讲raccheck的中文讲座 有可能可以帮到你
