在 GGSCI 环境下,执行类似如下语句查看特定进程的状态。
b.启用 FORCE LOGGING 归档模式(可选)当需要同步 NOLOGGING 模式的对象时,需要启用 FORCE LOGGING 归档模式。启用步骤如下语句。(1).检查 FORCE LOGGING 模式状态SQL> SELECT FORCE_LOGGING_MODE FROM V$DATABASE;(2),启用 FORCE LOGGING 模式SQL> ALTER DATABASE FORCE LOGGING;ALTER SYSTEM SWITCH LOGFILE;c.启用附加日志在 GGSCI 环境下,通过以下命令添加表级的附加日志GGSCI> ADD TRANDATA <schema.table_name>对于 schema 级的附加日志,可以通过以下命令添加。GGSCI> ADD SCHEMATRANDATA <schema_name>d.配置流池(stream pool)大小在抽取进程启用的数据库(抽取源库或 downstream 库)上,需配置流池大小,以应用于 logmining Server。SQL> ALTER SYSTEM SET streams_pool_size=<pool_size> scope=both sid=‘*‘;注意:流池大小由集成抽取参数 MAX_SGA_SIZE 及 PARALLELISM 决定,推荐公式为 (MAX_SGA_SIZE * PARALLELISM) * 1.25
a.备份软件目录
Back up the current Oracle GoldenGate working directories.b.修改抽取进程参数大多数情况下,传统抽取模式下的抽取进程参数同样适用于集成抽取模式下的抽取进程,此时需按需修改抽取进程参数。例如:设置集成抽取进程单个 logminner 进程使用 SGA 大小为 100M,logminner 进程数为 1。TRANLOGOPTIONS INTEGRATEDPARAMS (MAX_SGA_SIZE 100, PARALLELISM 1)c.GGSCI 环境下登陆源端数据库使用类似如下语句,在 GGSCI 环境下登陆源端数据库。GGSCI> dblogin userid goldengate, password Goldengate_2015d.注册抽取进程以挖掘数据库GGSCI> REGISTER EXTRACT <group> DATABASEe.停止抽取进程GGSCI> STOP EXTRACT <group>f.检查进程是否允许升级为集成抽取模式Issue the following command to determine whether the upgrade command can be issued. Transactions that started before the registration command must be written to the trail before you can proceed with the upgrade. You may have to issue this command more than once until it returns a message stating that Extract can be upgraded.GGSCI> INFO EXTRACT <group> UPGRADEg.升级抽取进程至集成抽取模式GGSCI> ALTER EXTRACT <group> UPGRADE INTEGRATED TRANLOGh.重启抽取进程GGSCI> START EXTRACT <group>
