Diagnostics data was not saved to the credential store

在启动IAM的的时候出现了如下的错误
Info: Data source is: opss-DBDS

WLS ManagedService is not up running. Fall back to use system properties for configuration.
Error: Diagnostics data was not saved to the credential store.
Error: Validate operation has failed.
Need to do the security configuration first!
解决方案:
进行配置：
<MW_HOME>/oracle_common/common/bin/wlst.sh <IAM_HOME>/common/tools/configureSecurityStore.py -d <domaindir> -c IAM -p <opss_schema_password> -m create

[oracle@training bin]$ /u01/iam/oracle_common/common/bin/wlst.sh /u01/iam/Oracle_IAM1/common/tools/configureSecurityStore.py -d /u01/iam/user_projects/domains/iam_domain -c IAM -p welcome1
-m create

让配置生效：
<MW_HOME>/oracle_common/common/bin/wlst.sh <IAM_HOME>/common/tools/configureSecurityStore.py -d <domaindir> -m validate

[root@training bin]# /u01/iam/oracle_common/common/bin/wlst.sh /u01/iam/Oracle_IAM1/common/tools/configureSecurityStore.py -d /u01/iam/user_projects/domains/iam_domain -c IAM -p welcome1 -m
