oracle 18c 安裝報ora-12754問題的解決

目前oracle發佈的18c,只能安裝在雲上,若是咱們安裝在本身機器上,使用dbca建立實例時,會報ora-12754的錯誤,有辦法解決沒有呢?
答案是確定的,有兩種辦法,一是上oracle 雲上拷貝libserver18.a文件來解決,二是,直接修改參數_exadata_feature_on=true,以後,也能夠啓動:

Instead of changing lib file one can get the database running as follows -
1. instead of creating database using dbca, use dbca to get the scripts.
2. there will be 3 init* files. Modify all of them just place _exadata_feature_on=true.
3. execute xxxx.sh script to run and build database.

後面應該很快應該就有本地的安裝介質出來,我選擇了後者來解決.

而後,開啓防火牆,就能夠訪問了.

[root@desktop0 ~]# firewall-cmd --permanent --add-port=5501/tcp
success
[root@desktop0 ~]# firewall-cmd --permanent --add-port=1521/tcp
success

以上測試在centos 7.4上經過.
