新装了Cognos8.3，内容数据库使用oracle，并测试成功，启动cognos时报如下错误：
[Launching a JVM using 'Maximum memory in MB']
1. Successfully launched a test JVM with the memory setting of '768'. Note that this does not guarantee that Cognos 8 will start and run successfully.
To see which JVM options are based on this setting, view c8_location/bin/bootstrap_
.xml and see your JVM documentation for an explanation of those options.
[Archive Local File System Root]
1. Since the value is empty, the feature is disabled. There is nothing to test.
[Validate mail server properties.]
1. [ ERROR ] The mail server cannot be reached.
[Start Service]
1. [ ERROR ] CFG-ERR-0103 Unable to start Cognos 8 service.
Execution of the external process returns an error code value of '-1'.
请问有没有见过这个错误的，帮忙解决下！ 收起
