使用 REXX 访问 Teradata 输出和 DB2 输出时出现问题

发布于 2024-08-05 03:52:57 字数 2102 浏览 6 评论 0原文

我有一个 REXX 作业,需要从 Teradata(使用 BTEQ)和 DB2 读取数据。目前,我可以让它从 Teradata 或 DB2 读取数据,但不能同时读取两者。当我尝试从两者中读取时,Teradata(首先运行)工作正常,但 DB2 读取在尝试打开游标时给出 RC(1) 错误。

从 Teradata 读取的代码(大体上复制自 http://www.teradataforum.com/teradata /20040928_131203.htm):

ADDRESS TSO "DELETE BLAH.TEMP"
"ALLOC FI(SYSPRINT) DA(BLAH.TEMP) NEW CATALOG SP(10 10) TR RELEASE",
   "UNIT(SYSDA) RECFM(F B A) LRECL(133) BLKSIZE(0) REUSE"
"ATTRIB FBATTR LRECL(220)"
"ALLOC F(SYSIN) UNIT(VIO) TRACKS SPACE(10,10) USING(FBATTR)"
/* Set up BTEQ script */
QUEUE ".RUN FILE=LOGON"
QUEUE "SELECT COLUMN1 FROM TABLE1;"
/* Run BTEQ script */
"EXECIO * DISKW SYSIN (FINIS"
"CALL 'SYS3.TDP.APPLOAD(BTQMAIN)'"; bteq_rc = rc
"FREE FI(SYSPRINT SYSIN)"
/* Read and parse BTEQ output */
"EXECIO * DISKR SYSPRINT (STEM BTEQOUT. FINIS"
DO I = 1 to BTEQOUT.0
   ...
END

从 DB2 读取的代码:

ADDRESS TSO "SUBCOM DSNREXX"
IF RC THEN rcDB2 = RXSUBCOM('ADD','DSNREXX','DSNREXX')
ADDRESS DSNREXX "CONNECT " subsys

sqlQuery = "SELECT COLUMN2 FROM TABLE2;"

ADDRESS DSNREXX "EXECSQL DECLARE C001 CURSOR FOR S001"
IF SQLCODE <> 0 THEN DO
   SAY 'DECLARE C001 SQLCODE = ' SQLCODE
   EXIT 12
END
ADDRESS DSNREXX "EXECSQL PREPARE S001 FROM :sqlQuery"
IF SQLCODE <> 0 THEN DO
   SAY 'PREPARE S001 SQLCODE = ' SQLCODE SQLERROR
      EXIT 12
END
ADDRESS DSNREXX "EXECSQL OPEN C001"
IF SQLCODE <> 0 THEN DO
   SAY 'OPEN C001 SQLCODE = ' SQLCODE
   EXIT 12
END

ADDRESS DSNREXX "EXECSQL FETCH C001 INTO :col2"
IF SQLCODE <> 0 THEN DO
   SAY 'FETCH C001 SQLCODE = ' SQLCODE
   EXIT 12
END

我怀疑这与我使用 SYSPRINT 和 SYSIN 有关。有人知道我怎样才能让它发挥作用吗?

谢谢。

所提出的问题实际上是错误的。很抱歉没有早点纠正这个问题。

我真正做的是这样的:

ADDRESS TSO "SUBCOM DSNREXX" 
IF RC THEN rcDB2 = RXSUBCOM('ADD','DSNREXX','DSNREXX') 
ADDRESS DSNREXX "CONNECT " subsys 

...然后是从 DB2 读取一小部分,然后是从 Teradata 读取的代码,然后是从 DB2 读取的更多代码。当将此更改为先从 Teradata 读取,然后再与 DB2 进行任何操作时,它就起作用了。

I have a REXX job that needs to read from both Teradata (using BTEQ) and DB2. At present, I can get it to either read from Teradata or DB2, but not both. When I try to read from both, the Teradata one (which runs first) works fine but the DB2 read gives an error of RC(1) upon attempting to open the cursor.

Code to read from Teradata (by and large copied from http://www.teradataforum.com/teradata/20040928_131203.htm):

ADDRESS TSO "DELETE BLAH.TEMP"
"ALLOC FI(SYSPRINT) DA(BLAH.TEMP) NEW CATALOG SP(10 10) TR RELEASE",
   "UNIT(SYSDA) RECFM(F B A) LRECL(133) BLKSIZE(0) REUSE"
"ATTRIB FBATTR LRECL(220)"
"ALLOC F(SYSIN) UNIT(VIO) TRACKS SPACE(10,10) USING(FBATTR)"
/* Set up BTEQ script */
QUEUE ".RUN FILE=LOGON"
QUEUE "SELECT COLUMN1 FROM TABLE1;"
/* Run BTEQ script */
"EXECIO * DISKW SYSIN (FINIS"
"CALL 'SYS3.TDP.APPLOAD(BTQMAIN)'"; bteq_rc = rc
"FREE FI(SYSPRINT SYSIN)"
/* Read and parse BTEQ output */
"EXECIO * DISKR SYSPRINT (STEM BTEQOUT. FINIS"
DO I = 1 to BTEQOUT.0
   ...
END

Code to read from DB2:

ADDRESS TSO "SUBCOM DSNREXX"
IF RC THEN rcDB2 = RXSUBCOM('ADD','DSNREXX','DSNREXX')
ADDRESS DSNREXX "CONNECT " subsys

sqlQuery = "SELECT COLUMN2 FROM TABLE2;"

ADDRESS DSNREXX "EXECSQL DECLARE C001 CURSOR FOR S001"
IF SQLCODE <> 0 THEN DO
   SAY 'DECLARE C001 SQLCODE = ' SQLCODE
   EXIT 12
END
ADDRESS DSNREXX "EXECSQL PREPARE S001 FROM :sqlQuery"
IF SQLCODE <> 0 THEN DO
   SAY 'PREPARE S001 SQLCODE = ' SQLCODE SQLERROR
      EXIT 12
END
ADDRESS DSNREXX "EXECSQL OPEN C001"
IF SQLCODE <> 0 THEN DO
   SAY 'OPEN C001 SQLCODE = ' SQLCODE
   EXIT 12
END

ADDRESS DSNREXX "EXECSQL FETCH C001 INTO :col2"
IF SQLCODE <> 0 THEN DO
   SAY 'FETCH C001 SQLCODE = ' SQLCODE
   EXIT 12
END

I suspect that this has something to do with my use of SYSPRINT and SYSIN. Anyone know how I can get this to work?

Thanks.

Edit

The question as stated was actually wrong. Apologies for not correcting this earlier.

What I had really done was have this:

ADDRESS TSO "SUBCOM DSNREXX" 
IF RC THEN rcDB2 = RXSUBCOM('ADD','DSNREXX','DSNREXX') 
ADDRESS DSNREXX "CONNECT " subsys 

...followed by a small read from DB2, then followed by the code to read from Teradata, followed by more code to read from DB2. When this was changed to reading from Teradata first before having anything to do with DB2 at all, it worked.

我认为这与 SYSPRINT 或 SYSIN 没有任何关系。

我认为您得到的是 TSO RC = 1,而不是 SQLCODE = 1(因为没有 1 的 SQLCODE。1

是警告,-1 是错误。您可以在 DB2 应用程序编程中查找此信息)
和 SQL Guide

打开 TRACE R 并运行它。

有一些变量(如下所示)显示有关错误/警告的信息。

22 *-* ADDRESS DSNREXX "EXECSQL OPEN C1"                                  
   >>>   "EXECSQL OPEN C1"                                                
   +++ RC(1) +++                                                          
23 *-* IF SQLCODE <> 0                                                    
28 *-* SAY 'SQLSTATE='sqlstate', SQLERRMC='sqlerrmc', SQLERRP='sqlerrp    

SQLSTATE=00000、SQLERRMC=、SQLERRP=DSN
29 - SAY 'SQLERRD='sqlerrd.1', 'sqlerrd.2', 'sqlerrd.3', 'sqlerrd.4',',
sqlerrd.5', 'sqlerrd.6
SQLERRD=0, 0, 0, -1, 0, 0
32 - SAY 'SQLWARN='sqlwarn.0', 'sqlwarn.1', 'sqlwarn.2', 'sqlwarn.3',',
sqlwarn.4'、'sqlwarn.5'、'sqlwarn.6'、'sqlwarn.7'、'、
sqlwarn.8'、'sqlwarn.9'、'sqlwarn.10
SQLWARN= , N, , , , 2, , , , ,

例如,当两者一起使用时,可能会出现内存不足的情况。

I don't think this has anything to do with SYSPRINT or SYSIN.

I think you are getting TSO RC = 1, not SQLCODE = 1 (because there is no SQLCODE of 1.

1 is a warning, -1 is an error. You can look this up in the DB2 Application Programming
and SQL Guide

Turn on TRACE R and run it.

There are variables (shown below) that display info about the error/warning.

22 *-* ADDRESS DSNREXX "EXECSQL OPEN C1"                                  
   >>>   "EXECSQL OPEN C1"                                                
   +++ RC(1) +++                                                          
23 *-* IF SQLCODE <> 0                                                    
28 *-* SAY 'SQLSTATE='sqlstate', SQLERRMC='sqlerrmc', SQLERRP='sqlerrp    

SQLSTATE=00000, SQLERRMC=, SQLERRP=DSN
29 - SAY 'SQLERRD='sqlerrd.1', 'sqlerrd.2', 'sqlerrd.3', 'sqlerrd.4',',
sqlerrd.5', 'sqlerrd.6
SQLERRD=0, 0, 0, -1, 0, 0
32 - SAY 'SQLWARN='sqlwarn.0', 'sqlwarn.1', 'sqlwarn.2', 'sqlwarn.3',',
sqlwarn.4', 'sqlwarn.5', 'sqlwarn.6', 'sqlwarn.7',',
sqlwarn.8', 'sqlwarn.9', 'sqlwarn.10
SQLWARN= , N, , , , 2, , , , ,

For example, it could be that when both are used together, there is not enough memory.
