Symptoms

环境信息： 
Oracle Linux 7.4 running UEK 4.1.12-124.48.5
Oracle Database 19c with Clusterware 19.8.0.0
Avamar Client and Plugin version, 19.3.100-149

在备份开始失败之前，未对 RMAN 脚本进行任何更改。脚本均使用可选参数 --taskfile。

RMAN 错误消息堆栈显示如下消息。 
ORA-19559: error sending device command: "--prefix=19/orcl10/
ORA-19557: device error, device type: SBT_TAPE, device name:

在 sbtio.log 中看到一些指示问题的行。

Cause

检查 /etc/sysctl.conf 中的已配置值是否显示预期值。

kernel.sem="400 150000 400 500"


但是，修补后的 Oracle Linux 7.4 未观察到这一点。

Value post-patching - kernel.sem = 250 32000 100 128
Configured value not being observed - kernel.sem = 400 150000 400 500

Resolution

客户手动重置 kernel.sem 参数以匹配在 中配置的值 /etc/sysctl.conf。此更改解决了问题，在应用正确的值后，备份开始成功运行。
