1.GoldenGate 19.1 新特性概覽
a.支持Oracle數據庫19.1
長期支持發布版本。集成Oracle GoldenGate 12.3版的最終補丁集更新。
b.微服務的安全性和可管理性增強
與密鑰管理系統集成，支持DMZ環境。Defaults changed to TLS1.2, Digest Auth, Strong Password Verifier
Managed profiles for AutoStart, AutoRestart, and Key Management.
c.性能和可伸縮性的改進
並行復制性能和可伸縮性上的改進。
遠程集成捕獲性能可承受高延遲網絡
d.易用性
更為簡便的軟件版本升級. 增強的 heartbeats 以簡化復制恢復. 遠程cross-endian 集成捕獲簡化了中間機和雲部署.更好的智能默認設置，使您無需為常見用例設置參數。
無需安裝客戶端遷移到雲端– OCI Marketplace 方案
Cross endian遠程集成捕獲允許遠程抓取本地部署數據庫，從而更容易遷移到雲。
2.MySQL –雙向SSL支持
Supply the full paths of the following:
certificate authority (ca.pem)
client certificate (client-cert.pem)
client key (client-key.pem)
Use SETENV in Extract/Replicat:
SETENV (MYSQL_OPT_SSL_CA='/var/lib/mysql.pem')
SETENV (MYSQL_OPT_SSL_CERT='/var/lib/mysql/client-cert.pem')
SETENV (MYSQL_OPT_SSL_KEY='/var/lib/mysql/client-key.pem')
3.SQL Server – Automatic TLS 1.2 Detection/Support
Support added for TLS 1.2 with GoldenGate 12.3.
Required Extract parameter: DBOPTIONS DRIVER SQLNCLI11
Automatically supported by Replicat: No extra parameter
GoldenGate 19.1 Automatically supports w/o DBOPTIONS.
Extract no longer requires DBOPTIONS DRIVER SQLNCLI11 parameter.
a.SQL Server –TRANLOGOPTIONS TRANCOUNT.
通過參數可控制通過Extract / procedure調用獲取的事務數
默認值為10;增加該值可以提高捕獲率； 取決於workload類型
SQL Server – 改進的 Extract內存管理.
large transactions的內存消耗減少
b.SQL Server –部署更為靈活
GoldenGate Installs on Linux.
GoldenGate for Windows SQL Server 介質可安裝在Linux
支持 OEL/RHEL 6 and 7
Perfect solution for GoldenGate application hub or cloud based deployments
Read-Only Routing to Always On Secondary.
GoldenGate capture routes to Always On Secondary, reducing overhead on Primary database
Requires Availability Group to be properly configured for read-only routing
Listener must be configured for the Availability Group
Extract’s DSN connection set to Listener\Instance
4.GoldenGate 19.1 新特性-DB2 iSeries
GoldenGate 安全特性
Master Key encryption via WALLET Method.
Supports AES encryption:
o ENCRYPTTRAIL | DECRYPTRAIL {AES128 | AES192 | AES256}
o RMTHOST ENCRYPT {AES128 | AES192 | AES256}
通過 CREDENTIALSTORE 加密用戶名密碼.
通過創建USERIDALIAS 來代替在參數文件中明文顯示用戶名密碼。
Db2 for iSeries –TRANLOGOPTIONS BUFSIZE
控制捕獲進程緩存從transaction log讀取的數據
較高的值可以提高捕獲性能，但會增加內存消耗
•Online Schema Change Tracking.
Support for online TABLE CREATE, DROP and ADD, ALTER, DROP COLUMN commands in the Extract without stopping and restarting the Extract to get the new table metadata for the Extract. Will port this to other supported DBMS’s in the future.
•增強的時間戳支持
All DB2 Platforms (LUW, iSeries, zSeries) – 支持 12 位精度Timestamp 數據
•Manage Long Running Transactions
All DB2 Platforms (LUW, iSeries, zSeries) – SHOWTRANS, SKIPTRANS, FORCETRANS
•支持DECFLOAT 數據類型
All DB2 Platforms (LUW, iSeries,zSeries)
