使用32位InstantClient，PL/SQL Developer连接Oracle：
•1. 下载32位Oracle InstantClient，并展开到某目录，例如C:\instantclient-basic-nt-11.2.0.2.0；
•2. 将系统的tnsnames.ora拷贝到该目录下；
•3. 在PLSQL Developer中设置Oracle_Home和OCI Library：
ToolsPreferencesOracleConnection：
Oracle_Home： C:\instantclient-basic-nt-11.2.0.2.0
OCI Library： C:\instantclient-basic-nt-11.2.0.2.0\oci.dll
•4. 在PLSQL Developer目录下新建如下bat文件，替换其快捷方式，启动PLSQL Developer：
@echo off

ORA-1578 ORA-1578一般为Oracle检测到存在物理坏块问题，包括其检测数据块中的checksum不正确，或者tail_chk信息不正确等。 ORA-1578 is reported when a block is thought to be corrupt on read.

ORA-1410
ORA-1410错误常见于从INDEX或其他途径获得的ROWID,到数据表中查询发现没有对应的记录。
该错误可能因为数据表与其索引存在不一致，也可能是分区的数据表本身存在问题。
This error is raised when an operation refers to a ROWID in a table for which there is no such row.
The reference to a ROWID may be implicit from a WHERE CURRENT OF clause or directly from a WHERE ROWID=… clause.
ORA 1410 indicates the ROWID is for a BLOCK that is not part of this table.

OERR: ORA 1410 “invalid ROWID”
ORA-8103
该ORA-8103可能由多个BUG引起，例如LOB在10.2.0.4之前可能会由于BUG覆盖了另一张表的segment header，导致出现ORA-8103错误。
诊断该问题可以从数据表的segment header和data_object_id入手。
The object has been deleted by another user since the operation began.
If the error is reproducible, following may be the reasons:-
a.) The header block has an invalid block type.
b.) The data_object_id (seg/obj) stored in the block is different than the data_object_id stored in the segment header. See dba_objects.data_object_id and compare it to the decimal value stored in the block (field seg/obj).

ORA-8102 ORA-8102常见于索引键值与表上存的值不一致。 An ORA-08102 indicates that there is a mismatch between the key(s) stored in the index and the values stored in the table. What typically happens is the index is built and at some future time, some type of corruption occurs, either in the table or index, to cause the mismatch.

ORA-1499 对表和索引做交叉验证时发现问题 An error occurred when validating an index or a table using the ANALYZE command.
One or more entries does not point to the appropriate cross-reference.
Index
索引
ORA-1499. Table/Index row count mismatch
OERR: ORA-1499 table/Index Cross Reference Failure – see trace file
ORA-1498 Generally this is a result of an ANALYZE … VALIDATE … command.
This error generally manifests itself when there is inconsistency in the data/Index block. Some of the block check errors that may be found:-
a.) Row locked by a non-existent transaction
b.) The amount of space used is not equal to block size
c.) Transaction header lock count mismatch.
While support are processing the tracefile it may be worth the re-running the ANALYZE after restarting the database to help show if the corruption is consistent or if it ‘moves’.
Send the tracefile to support for analysis.
If the ANALYZE was against an index you should check the whole object. Eg: Find the tablename and execute:
ANALYZE TABLE xxx VALIDATE STRUCTURE CASCADE; Block
OERR: ORA 1498 “block check failure – see trace file”
ORA-26040 由于采用过nologging/unrecoverable选项的redo生成机制，且做过对应的recover，导致数据块中被填满了0XFF，导致报错ORA-26040。 Trying to access data in block that was loaded without redo generation using the NOLOGGING/UNRECOVERABLE option.

从索引获得的ROWID，对应到数据表时发现不存在数据行错误。
一把是一致性度consistent read问题
Oracle is trying to access a row using its ROWID, which has been obtained from an index.
A mismatch was found between the index rowid and the data block it is pointing to. The rowid points to a non-existent row in the data block. The corruption can be in data and/or index blocks.
ORA-600 [12700] can also be reported due to a consistent read (CR) problem.

ORA-600[4194] 主要是redo记录与回滚rollback/undo的记录不一致 A mismatch has been detected between Redo records and rollback (Undo) records.
We are validating the Undo record number relating to the change being applied against the maximum undo record number recorded in the undo block.
This error is reported when the validation fails. Undo

ORA-600[4137] transaction id不匹配，问题可能存在与回滚段中或者对象本身存在讹误 While backing out an undo record (i.e. at the time of rollback) we found a transaction id mis-match indicating either a corruption in the rollback segment or corruption in an object which the rollback segment is trying to apply undo records on.
This would indicate a corrupted rollback segment. Undo/Redo

ORA-600[2103] Oracle is attempting to read or update a generic entry in the control file.
If the entry number is invalid, ORA-600 [2130] is logged. Control File
ORA-600 [2130] “Attempt to access non-existant controlfile entry”
ORA-600[4512] Oracle is checking the status of transaction locks within a block.
If the lock number is greater than the number of lock entries, ORA-600 [4512] is reported followed by a stack trace, process state and block dump.
This error possibly indicates a block corruption. Block
ORA-600 [4512] “Lock count mismatch”
ORA-600[2662] 主要是发现一个数据块的SCN甚至超过了当前SCN，常规解决途径有调整SCN等，但11.2以后Oracle公司使较多调整SCN的方法失效了 A data block SCN is ahead of the current SCN.
The ORA-600 [2662] occurs when an SCN is compared to the dependent SCN stored in a UGA variable.
If the SCN is less than the dependent SCN then we signal the ORA-600 [2662] internal error. Block
ORA-600 [2662] “Block SCN is ahead of Current SCN”
ORA 600 [2662] DURING STARTUP
ORA-600[4097] 访问一个回滚段头以便确认事务是否已提交时，发现XID有问题 We are accessing a rollback segment header to see if a transaction has been committed.
However, the xid given is in the future of the transaction table.
This could be due to a rollback segment corruption issue OR you might be hitting the following known problem. Undo
“对于数据库而言，备份重于一切”是所有DBA心中谨记的格言，但现实环境千差万别，企业的数据库环境中数据备份空间不足，采购的存储设备短期内无法到货，甚至于虽然进行了备份但是却在数据恢复过程中发现备份实际不可用等问题均属常见的场景。
为了应对这些真实世界中常见的数据恢复困局，需要特殊的恢复手段才能恢复其ORACLE DB中的数据。可以应对在完全没有备份情况下的SYSTEM表空间丢失、误操作ORACLE数据字典表、由于断电引起的数据字典不一致等数据库无法顺利打开的场景，也可以挽回误截断(Truncate)/删除(Delete)/业务数据表等人为的误操作，并从容恢复数据。
甚至于仅仅接触过ORACLE数据库几天的非DBA 人员也可以轻松地使用PRM，这得益于PRM简单的安装、和全程图形化的人机交互界面；实施恢复的人员不需要专业的数据库知识，不需要学习任何命令，更无需了解数据库底层的存储结构。仅仅需要轻轻点击几下鼠标就能从容恢复数据。
对比传统恢复工具DUL，DUL是ORACLE原厂内部恢复工具，其使用需要通过ORACLE内部流程，一般仅有购买了ORACLE原厂的现场服务的用户能够在原厂工程师的协助下使用该工具。PRM打破了只有少数专业人士才能实施数据库恢复任务的限制，极大地缩短了从数据库故障到完整恢复数据的失败时间,降低了企业恢复数据的总成本。
