网站按照规模分为哪几类,wordpress的标签设置,seo网站优化培训怎么做,动画制作精灵现在需要在一个测试环境创建1个为AL32UTF8的PDB,2个ZHS16GBK的PDB
这种情况下,必须先创建的CDB为AL32UTF8,下面是具体步骤:
1.AL32UTF8的pdb在建实例的时候一起创建完成
2.创建第一个ZHS16GBK的PDB cdr,通过pdbseed来克隆:
SQL create pluggable database cdr admin us…现在需要在一个测试环境创建1个为AL32UTF8的PDB,2个ZHS16GBK的PDB
这种情况下,必须先创建的CDB为AL32UTF8,下面是具体步骤:
1.AL32UTF8的pdb在建实例的时候一起创建完成
2.创建第一个ZHS16GBK的PDB cdr,通过pdbseed来克隆:
SQL create pluggable database cdr admin user suq identified by suq file_name_convert(pdbseed,cdr);
SQL alter pluggable database cdr open;
SQL alter session set containercdr;
SQL alter system enable restricted session;
SQL alter pluggable database cdr character set internal_use zhs16gbk;
SQL shutdown immediate
SQL startup
3.创建第二个pdb cdrlog,通过克隆cdr来实现:
SQL create pluggable database cdrlog from cdr file_name_convert(cdr,cdrlog);
SQL alter pluggable database cdrlog open;
SQL alter pluggable database all save state;
4.检查每个pdb的字符集
SQL show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED
